Railway tamper re-engineering is impressive Geomagical feat
Here's the deal: Reverse engineer a railroad tamper casting based on 40-year-old drawings that don't come close to matching the physical casting. It will be impossible to capture all the surfaces with a scanner, and you'll need to invent a couple of new approaches to create your digital model and verify its accuracy. Your final product — a complete set of accurate digital patterns that can be used to make new castings, including cores and core boxes — must be delivered in two weeks. Read the full article
How black can be cool on hot days
Dark surfaces of building roofs and facades attract heat, but light surfaces remain distinctly cooler. Some innovative pigments from BASF now make it possible for surfaces to heat up much less in the sun despite their dark color: Paliogen Black, Lumogen Black, and Sicopal Black. In contrast to carbon black, the standard black pigments, the BASF offerings reflect most of the invisible near infrared (NIR) radiation that accounts for more than 50% of the total incident solar energy.

The performance of a lifetime The 35000 series (size 14) double stack hybrid linear actuators provide higher force, longer life and improved performance. The various patent pending designs deliver exceptional performance and new linear motion design opportunities. Three designs are available, captive, non-captive and external linear versions. The 35000 Series is available in a wide variety of resolutions - from 0.00012" (.003048 mm) per step to 0.00192" (.048768 mm) per step. The motors can also be microstepped for even finer resolutions. The Size 14 actuator delivers thrust of up to 50 lbs. (23 Kg). For more information visit Haydon Switch & Instrument online.
Scientists make ultra-strong magnets quickly, cost effectively
Northeastern University researchers have invented a rapid, high-volume, and cost-effective one-step method for producing pure Samarium Cobalt rare earth permanent magnet materials. Samarium Cobalt is a mainstay material for several industries that rely on high-performance motor and power generation applications, including the Department of Defense and the automotive industry.

Wheels: Off-highway Surprising benefits of hydraulic-to-electric actuator conversion
Many manufacturers of off-highway equipment have replaced hydraulic cylinders with electric actuators in order to eliminate pumps, hoses, and valves, and make vehicles smaller, lighter, and quieter. They have taken advantage of the flexibility in interfacing with control systems to provide a wide range of new features and capabilities. Read the full article
5-Star Product: Torque tool testing and documenting just got easier
The LTT torque analyzer from Mountz is designed for torque calibration, joint testing, auditing, or for force and load measurement or verification of load cells. Meeting the demands to test multiple torque ranges for various torque tools used in production, maintenance, and calibration labs, the LTT features the new EZ-Plug & Play technology, which is an auto-recognition system with Mountz torque sensors.
