Sticky PostingsHow do e-bikes work?
How e-bikes work is by assisting your pedaling. Electric bikes are everyday bicycles with an added battery-powered electric motor. Although capable of pushing you along without your help, electric bikes perform noticeably better when you pedal. The average "couch potato" who normally rides at 10 mph can ride at 15-20 mph using the same effort. He can also expect a range of 10 miles, with a recharge time of several hours. Do you remember that easy pedaling after you get your bike up to speed? Thats the cruising feeling you get all the time with an electric bike.
Power, when activated by a throttle on the handlebar (power-on-demand) or in response to your pedaling (ped-elec), gives you an immediate, nearly silent push. When you release the throttle (or stop pedaling), the motor coasts or "freewheels" - like when you stop pedaling a regular bike. Standard bicycle hand brakes and gearing round out the controls.
"Power-on-demand" means just that - no pedaling required! Although all electric (or "electric-assist") bikes are designed to work with your pedaling, power-on-demand allows you to break the rule. Most systems offer a variable speed control, although some are simply on/off (like the yellow switch pictured). A "ped-elec" wont deliver motor power unless it senses you are pedaling. And its "power output to pedal pressure" ratio is often adjustable. Most people find 400-watt motors adequate for their needs, although folks with steep hills may want more power. Some bikes offer through-the-gearing power assist - i.e. the force of the motor goes through the bikes gearing system - which provides better hill-climbing and top-end speed than direct drive systems with motors of the same wattage rating.
Electric bikes come in two basic designs - adaptive and purpose-built. The adaptive type starts with a bicycle and adds a drive system to it. A purpose-built e-bike is designed from the ground up. Adaptives are less expensive, less stylish, and may require installation (allow 3 hours if youre familiar with tools; otherwise your local bikeshop mechanic will charge about $75). Purpose-builts generate interesting designs and features (like brake-activated tail lights). Users of both types enjoy easy acceleration, hill climbing, and cutting through headwinds. Rechargeable batteries, usually sealed lead-acid, provide power for the electric drive motors. Charging costs less than 5¢ of electricity from common 110 VAC wall outlets. Charging times vary widely due to charger output and battery capacity, but you can expect to recharge in less than 8 hours with most stock chargers. Quick chargers are available.
Mopeds differ from e-bikes in that they generate more speed, risk, range, expense, pollution, and legal issues. Top speed of mopeds is limited by law to 30 mph. Often, a drivers license and registration is required. An electric bike, which by law is limited to a top speed of 20 mph, reduces the risk of serious injury. Its shorter range of 8-20 miles is plenty for errands and short commutes. E-bikes are the cleanest motorized vehicles - both in terms of air pollution and noise. If you own a bike, you can motorize it for as little as $500. Or buy a purpose-built e-bike for up to $3000. Either way, you can ride your e-bike without a drivers license, vehicle registration, or insurance.

Machine makers see year of recovery in ’10
What a difference a year makes.
For plastics machinery manufacturers, 2010 was a year of recovery, following the brutal recession that stretched from late 2008 through all of 2009.
Customers finally started to loosen their grip on their collective wallets. It all culminated with a solid K show in Germany — where some machinery executives fretted about long lead times and possible shortages of key components if the hot growth continues. Imagine that!
There weren’t many machinery deals and acquisitions this year. Two U.S. producers made news, for opposite reasons, as Milacron LLC finally turned a profit and HPM shut down.
After struggling to survive the recession, Gloucester Engineering Co. got new life thanks to a new private equity owner.
October was marked, sadly, by two deaths, of Hans-Jürgen Matthesius and Elmar Spohr.
Nov. and Dec. 2009
Several European injection press manufacturers — including Engel Holding GmbH, Netstal AG and Arburg GmbH + Co. KG — returned their workers to full-time status, ending short-time working schedules, as the global machinery market began to improve.
January
HPM, the struggling maker of injection presses, sheet lines and die-casting equipment, closed its doors in Mount Gilead, Ohio.
February
Japan Steel Works Ltd. bought a majority stake in another Japanese injection press company, Meiki Co. Ltd.
March
Gloucester Engineering Co. was forced into Chapter 7 bankruptcy by three disgruntled creditors of the film equipment maker. The case was converted to a Chapter 11 reorganization in June, and under a new owner, private equity firm Blue Wolf Capital Partners LLC, company officials expect Gloucester to emerge from bankruptcy by the end of 2010 or early in 2011.
Engel Machinery Inc.’s president and CEO, Stephan Braig, left the injection press company to take the top job at Trexel Inc., which sells the MuCell process of microcellular foaming.
April
A Plastics News cover story reported strengthening demand for screws and barrels, signaling new investment at plastics factories.
June
Small-press supplier Boy Machines Inc. welcomed a new vice president of sales and service, Marko Koorneef. Boy Machine’s president, Robert Koch, a machinery veteran, was reassigned to handle special projects and Midwest sales.
September
Officials of Husky Injection Molding Systems Ltd. said Husky would introduce its first-ever all-electric injection molding machines at K 2010. Toyo Machinery and Metal Co. Ltd. supplies major components and subassemblies for the presses.
Michael Urquhart became Husky’s vice president of sales for North America, replacing Carmen Lowe, who is retiring.
October
The plastics industry gathered in Düsseldorf, Germany, for an upbeat K 2010. The show was marked by reports of a broad global recovery by plastics machinery companies.
Davis-Standard LLC bought Harrel Inc., a maker of small tubing extruders for the medical and appliance markets.
Italian blow molding machinery maker Techne SpA filed for protection from creditors.
Two well-known plastics machinery executives died in October. Extrusion equipment veteran Hans-Jürgen Matthesius, 63, died in Florence, Ky., of cancer. Forty-year-old Elmar Spohr, president of Agawam, Mass.-based blow molding machine supplier W. Müller USA Inc., died unexpectedly in Germany on the first day of K 2010 in Düsseldorf.

Armada workers reject contract
LINDSAY -- Workers at Lindsay's Armada Toolworks plant could face a lockout as early as Dec. 30 after workers voted 68% in favour of rejecting the company's final offer.
The contract for 146 Armada workers represented by the Canadian Auto Workers Local 222 expired at the end of November.
Armada has filed for a no-board report which would put the company in a legal position to lock out workers as of Dec. 30, according to a news release from the union.
"It has always been the CAW's position to bargain a fair and equitable agreement without an interruption of work," CAW national representative Keith Osborne stated in the release. "We hope the company feels the same way and returns to the bargaining table."
The plant has been in Lindsay for about nine years and makes zinc and aluminum die castings, injection-molded plastics and mechanical assemblies for General Motors, Ford, Chrysler, Opel and Volkswagen. The workers joined the CAW in 2004.

Monday, September 13. 2010Vented DIN-rail enclosure
Camden’s new vented CNMB/12 snap fit DIN-rail enclosure is 210 mm long and features ventilation slots moulded into both sides of the body to provide improved heat dissipation compared with fully enclosed models. Having moulded vents saves users the difficulties associated with machining enclosures, increasing productivity and reducing assembly costs. The moulded vents also result in a stronger moulding compared to a similar enclosure with machined ventilation slots.
The enclosure is supplied complete with 12 terminal guards as standard, eight perforated on 5,08 mm pitch and four solid. Its features include snap-on terminal covers to IP20 finger protection with perforated screwdriver and wire entry holes and tabs as standard, as well as spring loaded DIN-rail clips that can be snapped open to allow chassis/surface mounting. Terminal covers and snap-in panels can also be provided to customer specifications for volume orders. Other optional features include EMC shielded metallic coated boxes.

Camden Electronics has introduced an exciting new range of UK-manufactured snap-fit DIN rail enclosures sporting a wide variety of enhancements and improvements over the company's existing boxes and competing products. The enhancements and improvements result in a highly versatile DIN rail enclosure that can be adapted by users to meet almost any conceivable requirement.
Unlike competitive products, Camden's new patent-pending DIN rail mounting enclosures are fully UL94V0 flame retardant as they are moulded in polycarbonate instead of Noryl and other lower grade materials. Seven versions are available offering lengths of 17.5, 36, 53, 71, 89, 106 and 160mm all 90mm wide.
Offering greater versatility, Camden's new design features a number of enhancements to make mounting of PCBs easier. These include PCB guides to ensure boards are held in place firmly and moulded screw holes in the base to facilitate mounting of PCBs with heavier components such as relays or transformers. Up to three PCBs can be mounted horizontally while there are four mounting positions for vertical boards.
A further enhancement is that the enclosure base is fully sealed with none of the holes that are found on competing products. This avoids the need for any insulating pads and reduces assembly costs for users. The design of the enclosure is such that all tabs on the body have been eliminated to avoid small lugs that might break off.
Standard colour is grey (RAL 7035) although Camden can supply mouldings in black, green, red or blue for volume orders. In addition, the company can incorporate ventilation slots in its tooling for volume customers to avoid the need for machining by the end user. Besides reducing costs for the end user this facility also results in a stronger moulding compared to a similar enclosure with machined ventilation slots.
A range of standard snap-in panel covers in grey, transparent red or clear is available with a new polarisation feature that ensures correct mounting. The enclosures can also be supplied with a moulded top panel that can be screen printed and also enables the transparent red or clear snap-in panels to be mounted with a label underneath for example.
Additional special features include snap-on terminal covers to IP20 finger protection with perforated screwdriver and wire entry holes and tabs as standard and spring loaded DIN rail clips that can be snapped open to allow chassis/surface mounting. Camden can also supply an optional adaptor for G-rail mounting. Terminal covers and snap-in panels can also be provided to customer specifications for volume orders. Other optional special features include alternative black higher rated RTI material and EMC shielded metallic coated boxes.
Pioneer Plastics tries to restructure debt
Conn.-based Panolam Industries International, parent to Auburn's Pioneer Plastics, a manufacturer of laminates, has reached a tentative agreement with shareholders to let the company shed $151 million in debt.
Panolam, which bought Pioneer Plastics in 1999, posted $121 million in net losses in 2008 and $10 million in losses for the first quarter of 2009, according to filings with the Securities and Exchange Commission as reported by the Sun Journal. Citing the downturn in the housing industry, Pioneer Plastics laid off 48 employees - about 16% of its local work force - at the Auburn plant in December.
Shareholders filed a default notice in February. If approved, the tentative agreement would allow the company to eliminate $16 million in annual credit payments, according to the paper

Goodyear to Make National Transition to Steel Wheel Weights
AKRON, OH - Goodyear Tire & Rubber will use BADA steel wheel weights at its company-owned and Just Tires outlets. BADA weights are sold by Hennessy Industries, according to Modern Tire Dealer.
"This is a big win-win for BADA and Goodyear," says Kevin Keefe, Hennessy's vice president of marketing. (Hennessy has partnered with Myers Tire Supply to distribute BADA weights to Goodyear stores.)
"When a company of Goodyear's size and stature chooses BADA steel as a preferred alternative to lead (weights), it reinforces the many technical and environmental benefits of BADA's unique and patented wheel weight designs."
Goodyear, which has more than 600 company stores, has already made the transition from lead weights to steel weights in California, and plans to begin its national transition to steel weights this month.
"Like many large companies, we believe that offering eco-friendly products is part of our responsibility to our customers," says Jerry Alessia, Goodyear Retail's director of store support, reports Modern Tire Dealer.
