MATERIALS: The small spring applied brake series from Ogura (models MCNB 2, 5, and 10) have been redesigned and will now have a thinner profile. The brakes overall reduction in thickness is around 30 percent. Advances in friction material have allowed the brakes to maintain their same torque rating while eliminating the need for higher force springs and a correspondently higher wattage coil. The new thinner spring applied holding brakes are ideal for the servo motor and robotics industries where size and weight is always a concern. Since less steel is used in the coil shell and less copper in the windings, cost of the brakes are also lower than the current MCNB series. On some of the models, the outside diameter has been slightly reduced but all of the models have the same through whole mounting dimensions as the current MCNB brakes, so brake models will be interchangeable.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
