LONDON, UK - E4 is the name of the new ¡®Group Cooperation’ forming an alliance between four companies to help promote e-bikes in the UK. Electric Bike Corporation (EBC), Storck-Raddar, Hero Eco and Wisper have all come together with a common purpose to support electric bike sales in the UK.

Initially, E4’s focus will be targeted towards the trade, with plans for regional trade demo days, marketing support and the idea of greater cooperation for the major UK consumer shows.

Commenting on the group Ian Hughes of Storck-Raddar said: "The potential of the e-bike sector in the UK seems to be the subject of much industry debate. We look at the phenomenal growth in countries like Germany and the Netherlands and think, is this the way the UK market will go? E4 thinks yes, but there is some work to be done to get there. With four of the UK¡¯s e-bike distributors coming together we expect to make a significant impact in developing the sector far quicker than we would as single companies."

Paul Stanforth, EBC ’s managing director, said: "There are some very specific tasks that need to be undertaken, such as giving the trade an opportunity to see what is available and educating them in the latest technological developments. We have some very exciting plans and the first elements will be revealed in the coming weeks."

David Miall of Wisper said: "E4 has been in the making for several months now and I have to say, all the meetings have been some of the most positive I have attended. It really feels that we are all working together towards a common purpose, to promote e-bikes. Combined, we have decades of experience and there is a feeling that E4 will make a real difference to the sector."

Finally, Mark Loveridge of Hero Eco said: "The ebike market is potentially vast and E4 is ideally placed - with the right range of ebikes and a superb skill set of people - to reach a tipping point and deliver a sector that we all know is there."

Each of the four companies has a range of e-bikes that complement each other with little overlap when it comes to pricing, style and spec and E4 will work to promote all the group’s brands as well as the sector in general.

Vertical flow heat exchanger widely used as a heat exchanger. As the fluid flow in the shell longitudinally, the shell of the pressure drop lower than the baffle, integrated performance advantages of higher than the baffle, the heat exchanger has good development prospects. Existing bar gate bearing rod baffle heat exchanger are also some shortcomings, mainly in the following areas [1,2]: ¢Ù only at high Reynolds number in order to obtain high efficiency, low in the shell-Ray under low Reynolds number heat transfer efficiency, and sometimes even lower than the baffle heat exchanger; ¢Ú shell heat exchanger longitudinal flow of traffic fluctuations, especially in the case of flow dump pipe flow shortage, resulting in significant heat transfer coefficient reduced; ¢Û Rod Baffle arrangement for the convenience of the general rod baffle heat exchanger are used a large square or triangular spacing fabric tube, this structure will result in heat exchanger tube loose piping, heat exchanger diameter increases, the shell process flow to reduce, not conducive to improving the shell-side heat transfer coefficient.

In this paper, the aforementioned lack of heat exchangers, shell-side heat transfer coefficient to increase, increase the heat transfer area as a starting point, made a new holding structure reducer piping heat exchanger [3].

Carried out using cell flow and heat transfer in shell-side flow field of three-dimensional numerical simulation, and application of field synergy principle and field synergy on the shell side of the state were analyzed. The field synergy principle applied to evaluate the performance of the new holding structure among the complex structure of longitudinal flow heat exchanger shell velocity - temperature gradient vector angle between the proposed method of calculation.

2 The basic model and methods of field synergy

2.1 Reducing the heat exchanger piping clamp structure

The three main types of heat transfer through: improved heat transfer coefficient, heat transfer area to expand and increase the heat transfer temperature difference. Reducing new piping support structure is to increase heat transfer area, based on further improving the heat transfer coefficient. Reducing the vertical flow tubes clamp shell heat exchanger (Figure 1) the main features are: from the baffle gate baffle ring and connected to the baffle ring spaced groups of flat steel with a composition; flat with support large and small diameter tubes, welded baffle ring rod holes. By changing the structure of the new support, you can achieve the following objectives [4]: 30% increase in heat transfer area; get a good flow distribution, the formation of long-range longitudinal vortex, effectively thinning the tube boundary layer; shell-side fluid flow was vertical, local The holding structure with a jet, to change the shell flow field and temperature field synergy between the small increase in pressure drop the case, to improve the shell under low Reynolds number in fluid heat transfer efficiency, than the average longitudinal flow shell heat exchanger increased by 20%.Pipe Clamp

2.2 Convection heat transfer field synergy principle

"Field synergy" theory is over by Yuan [5] proposed a completely different with the traditional method of enhancement technology, namely, by improving the fluid velocity field and temperature field synergy degree of enhancement of heat transfer, the "field synergy" theory.

"Field synergy" theory of laminar convective heat transfer from the energy equation [5], the energy equation in the match as the internal convective heat flow in the boundary layer type analysis of the energy equation; by the heat equation points within the boundary layer is proposed to promote heat transfer enhancement of three ways: 1 increase the Reynolds number (Re);2 increased Prandtl number (Pr), change the physical properties of the flowing medium; 3 increasing the value of the dimensionless integral

Digital Lumens is using daylight to ratchet up the efficiency of its commercial LED light fixtures.
The company today is announcing a new product line that boosts the amount of light each fixture can give off and improves energy efficiency by up to 50 percent with an embedded daylight sensor.
Efficient LED lighting promises to bring significant energy savings to commercial and industrial customers because businesses tend to spend more money on lighting. But just like the consumer LED lightbulb market, the cost of LED fixtures is still higher than other lighting technologies.
Digital Lumens’ fixture, which is about the size of a desktop PC, combines an array of LED light sources with a networking chip. This connects fixtures to a centralized management application to schedule and control lights, thus improving efficiency. The product is designed for warehouse aisles and manufacturing spaces, and it pays back the initial higher cost within a year or two, according to the company.
The fixture’s daylight sensor enables it to gradually dim itself when there’s daylight available, leading to energy savings between 25 percent and 50 percent, according to the company.
Engineers decided to use digital sensors normally used for automatically dimming screens on cell phones, said Joseph Adiletta, senior product manager. Photo light sensors are normally added to an area after fixtures are put up, rather than being integrated into each fixture, he said.
Digital Lumens’ latest products also give off brighter light, between 10,000 and 26,000 lumens. That makes them suitable for a broader set of uses–and competitive with high-intensity discharge or fluorescent lamps–but by producing between 81 and 85 lumens per watt, they are more energy-efficient, said Michael Feinstein, vice president of sales and marketing.

Ryobi Die Casting will implement an IBM i-based ERP system from Solarsoft, the vendor announced recently. The manufacturer will implement iVP across its three plants in Indiana and one plant in Mexico.

Ryobi Die Casting Inc. (USA) manufactures a range of high pressure aluminum die castings for transmission cases and housings, cast engine blocks, steering housings, and structural parts for vehicles. The company, which is a tier-one supplier to the automotive OEMs, is based in Shelbyville, Indiana, where it operates a machining facility and two die casting plants. It also operates a die casting plant and a machining facility in Irapuato, Mexico. All told, the $350 million company employs about 950 people in North America.

Recently, Ryobi sought a replacement for its existing computer system. The company’s IT manager, Randy Burket, had used Solarsoft at a previous job and was familiar with the system, the company, and its employees. Solarsoft was one of several ERP packages in the running to win Ryobi’s business.

Burket says Ryobi eventually chose Solarsoft’s iVP system because of its functionality Excavator teeth. "It has everything we need so we don’t have to build our own features," he states in a press release. "Having previously dealt with other ERP packages and larger, more expensive pieces from SAP and [Oracle’s] JD Edwards, Solarsoft’s cost and value was the right fit for us."

The implementation of iVP will provide several immediate benefits for Ryobi, including the elimination of manual data entry and reporting. Burket says Ryobie is also looking forward to using Solarsoft’s EDI and shop floor reporting capabilities. Casting Machines "The ability to see what our machines are doing in real-time is another huge benefit," he says.

Solarsoft Business Systems was created following the April 2007 merger of two midmarket ERP software developers: CMS Manufacturing Systems of Richmond Hill, Ontario (near Toronto), and XKO Software of the U.K. The two companies were bought by the Los Angeles, California-based investment firm Marlin Equity Partners, which merged them into a single entity it named Solarsoft.

Most large centrifugal casting machine used to produce roll. In centrifugal casting, the mold (also called tube model) the speed is very important, particularly in roll production, the need for secondary cast (Tim core), in particular, speed and time and requires strict control of temperature. To meet the requirements of the roll casting process, we designed a large centrifugal casting machine control system, real-time control and dynamic tracking, precise control of centrifugal casting roll process. The last large-scale centrifuge control system, they use open-loop automatic / semi automatic control, electromagnetic speed control system, job stability is poor, many artificial factors. Through the improvement of hardware and software design, using Siemens AC drives (6SE70 series) or DC drive system (6RA70 series), the temperature sensor input, speed and vibration measurements host signal, programmable logic controller through real-time basis, as long as the interface to set the appropriate operating parameters, you can set automatic tracking technology curve; the entire production process to achieve a true closed-loop, automatic tracking control, eliminating manual intervention and more and other factors, improved product quality and production efficiency.
1 large centrifugal casting machine the main process parameters

(1) the initial growth rate of speed: the centrifuge began to rise still pouring from the requirements of speed;

(2) maintain the solidification rate: after casting to maintain the speed of the centrifuge;

(3) slow down the speed: slow down the speed that the shutdown speed.

2 System Hardware

By the industrial computer hardware, programmable logic controller PLC, analog input, output, DC converter or AC drive and peripheral equipment. Figure 1 is a block diagram of a large centrifuge control system.

IPC PLC completed major centrifugal casting machine through a remote real-time monitoring and management reporting of production, on-site centrifuge speed, cavity liquid metal temperature, bearing temperature, vibration centrifugal casting machine working status in real-time monitoring. Centrifugal casting process, the computer can automatically record continuously the temperature of liquid metal mold in the curve.

How it works: by the interface to set the main parameters centrifugal casting machine or out of the original product of process parameters, in line with the current product, the control curve displays the current products, according to the actual need to make sure, through the control buttons were issued for the start pouring, a casting, secondary casting and other signals; PLC based products, process parameters and analog input through on-site centrifugal casting machine to get the current actual speed, calculated by the actual needs of the analog output of a speed, while the centrifuge through the analog input vibration signals, temperature signals, real-time diagnosis of centrifugal casting machine working condition; centrifugal casting machine motor current signal real-time diagnosis of centrifuges load size, real-time display of their products work curve, confirm the quality of the product. Figure 2, Figure 3 for the Wuhan Iron and Steel Plant centrifuge parts used in large-scale electrical schematics.

3 Software Design

Purpose is to enable users to set up according to their own products, or call any of a variety of products, process parameters and process curve, that is, using the production formula in the form of time to refresh the program, according to the needs of users through the process parameters and on-site centrifuge working condition, motor working status real-time acquisition, real-time display in the form of animated figures and curves also showed an early warning to the user to solve practical problems in real-time program.

First, from the preservation of various process parameters on the interface can also be re-set various parameters to produce a new formula, the following table for the class roll casting process parameters. 】Beer Brewing

As the roll resulting in the secondary cast of time-critical, so timely, correct confirmation solidus temperature is the key to roll production. Observation of the past through artificial means to confirm the diagnosis solidus temperature, so the stability of product quality can not be guaranteed, and now through the software can automatically confirm the solidus temperature, automatic control downtime, thus ensuring the stability of roll quality , while the software itself by centrifugal casting machine vibration amplitude as well as automatic centrifuge bearing temperature measurement, timely forecasts of centrifuges working condition, there are issues can be tips, to ensure that the centrifuge work.

Temperature inflection point recognition software design based on the following two formulas:

Inflection point velocity Vi formula: Vi = V set-a (V-V actually set) (where A is a empirical coefficient);

Ki slope of the curve inflection point temperature is calculated:

Ki = ΣFj1-ΣFj/Ti

J1 which is (i-10 ~ i-6), j is (i-5 ~ i), the turning point of the top 10 values ​​in the top 5 after 5 value minus the value divided by the time that was the turning point temperature slope, see Fig. 4.

Pouring temperature of 1350 ℃, the solidus temperature of about 1100 ℃, centrifugal casting machine wheel speed 1400r/min (determined according to the casting diameter), braking time: large-scale pieces in 5min, gravity coefficient 100 ~ 110g.Eyelet Machine

Based on the above hardware configuration and software design principles, before the start of pre-production at the interface or process parameters set on the computer, check and correct your system running. First, control system design and calculation by the program will convert the initial growth rate of the analog output signal, the analog signal through DC converter or AC inverter drive motor within the centrifuge at the time of a uniformly accelerated from rest to the beginning the beginning of growth rate; centrifuge speed to reach the second step after the pouring temperature of molten iron, after pouring to maintain this speed for cooling coagulation; centrifuge at high speed cooling and solidification process for forming the mold cavity temperature measurement, When the mold cooling mold temperature down to a period of time solidus temperature (Figure 4, 1100 ℃), then the control system to control the centrifuge begins to decelerate, and must be within the time 3 2 centrifuge speed from the speed reduction to speed 3, that is shutdown; and then proceed to the next process is the second casting.

Breaker Brewing tastes success

EILEEN GODIN Times Leader Correspondent

PLAINS TOWNSHIP — After seven years of tinkering with recipes and per fecting their brew, the owners of the Breaker Brewing Company are ready to move out of a basement and set up shop in a former church.

Chris Miller of Plains Township and Mark Lehman of Hanover Township have poured much of their free time and effort to take a hobby of brewing beer first in Miller’s kitchen, then in his basement, to establishing a small business. The result is that the pair’s unique flavorful beers are now on tap at several area bars and restaurants and a growing demand for them to brew more.

That has led them to the next logical step, and it’s not Miller’s garage. They’re looking to expand their brewing capacity by buying and moving into a larger location with enough space not only brew more beer but also enough space so they can also open a restaurant and gift shop.

During their search for that optimum location, one spot has stood out to them: the former St. Joseph Church property at 783 E. Northampton St. in Wilkes-Barre Township. The property has two buildings on it, the former church and its school.

Sharing the same dream, Miller and Lehman said the former church will be renovated into a family oriented restaurant and gift shop whose atmosphere will be centered on the Wyoming Valley’s rich coal mining history.

“What I like to tell people is picture a fancy gift shop, like a museum gift shop, with a restaurant and brewery on site,” Miller said.

The former school will be used as the brewery giving them more room to meet their growing demands. The simple but sturdy structure of the buildings along with its central location and ample parking attracted them, Lehman said.

“We heard the property was going up for sale through some friends,” Lehman said.

The move to expand would give the two entrepreneurs the ability to meet requests for their product in two other eastern Pennsylvania markets.

“We had a lot of inquires from bars and restaurants in Allentown and Philadelphia,” Miller said. “But we need more space before committing ourselves.”

Looking around Miller’s small crowded basement, it is easy to understand the need for a larger space.

White bags of varieties of oats, wheat, and hops are stacked about 4-feet tall. A portion of the basement is divided into cooling and fermenting rooms, while a keg cleaner is on the opposite wall.

Their amber ales and darker malts are gaining popularity. Currently, they are providing their products to Elmer Suds in Wilkes-Barre and Grotto Pizza at Harveys Lake, to name a few.

The restaurant, they believe, is a natural transition and would be a welcomed amenity for the area. Lehman, a father of three, said the restaurant would be a family-oriented facility, which would offer creative foods as well as regular favorites for children.

The negotiations on purchasing the church building are ongoing, but Miller said it’s looking good. He said a closing could occur later this week.

Both Miller and Lehman are pleased with how their business, which started as a hobby, has grown. They attribute their recipe for success to hard work, thinking outside of the box, and determination. All, it should be noted, are traits of workers from the coal mining era.

The two longtime friends started their business in 2005 and took it to the commercial level in 2007, Miller said. It was not a simple move to make. Miller said filling out the necessary paper work with the Liquor Control Board combined with building a larger brewing system took about a year to complete.

Miller said their older system was a 55 gallon stainless steal drum system.

“We could not make enough with it,” he said. “Last summer we sold it and built this system.”

Building everything themselves from their brewing system to the wooden keg tab, Miller and Chris rolled up their sleeves and built a larger 120 gallon tank system.

“We could make more with this but we do not have enough fermentation room, not enough cooling capacity. We really need to go with 140 gallon tanks and go with double brew days. Kind of step things up a bit to catch up with all the bars.”

Although their recipes are stored safely away, the guys were willing to share their recipe for success. Miller said they built what they needed instead of buying it.

For example, he said, the coolers use Lehman’s grandmother’s old air conditioners. With a smile he said he tweaked it and changed the controls, but it works.

“We even built the keg cleaner controls,” he said.

Lehman said everything was done in a non-traditional way.

“Brewing in these plastic poly tanks is not traditional,” Lehman said. “Lots of wineries use them. We thought, ‘let’s try it’ and put in the valves and wheels, and they work.”

Though their methods are untraditional, the names of their beers overflow with the region’s coal mining tradition. Malty Maguire, Olde King Coal Stout, Lunch Pail Ale and Anthracite Ale are just a few of the aptly named brews.

The patch panel is a vital piece of equipment in many businesses; it allows network technicians to manage phone and internet connections easily. The purpose of the patch panel is to hold network connections; fundamentally it connects different components and outlets so that networks can operate effectively. In many cases patch panels are contained within a dedicated, air conditioned and temperature controlled room; this is because they produce a large amount of heat.

 Patch panel, Keystone jack , Face plate ,Network cabling, Wire management , Network cabling tool , DIP Switch , Clamp Module , Distribution box , Fiber coupler , 

The patch panel is used in many companies to control local area networks or LANs. That is not to say however that this is where the first patch panels were utilised. Many people will have seen this piece of equipment without really knowing it. Those archaic videos of phone operators plugging and unplugging phone connections were essentially carrying out the process of a patch panel. Today however the processes carried to by these operators have been automated.

Connections within the panels are made using patch cords. Cords are used extensively within the technology industries to connect computers to each other, to peripheral equipment and networks more generally. Understandably this massive use of cords can lead to a complete mess when it comes to networking. A patch panel enables the technician to order these cables effectively in a logical and simple manner. As connections are also made using sockets, the need for excessive soldering is removed.

In many instances patch panels are mounted on racks. At the front of the assembly are a number of short cables, each with a temporary connection within the front side. At the rear of the equipment there are typically longer wires that have permanent places to ensure the correct connections are made. Ultimately by utilising an array of patch panels the need for extremely expensive switching equipment is stymied.

Many industries utilise this form of equipment. Whilst it has already been stated that there use in the telecommunications industry is expansive, they are also used within recording and television studios, as well as in larger venues such as concert halls and cinemas. In this instance the panels do not control computer connections but are instead used to control electrical equipment such as microphones, speakers and video screens. In this instance they are often referred to as patch bays rather than the more general panel nomination. Even with this distinction they provide the user with similar benefits, that of ease of use and a more convenient connection process.
