Unit Conversion Tool
Convert popular spring units such as force, or retaining ring thrust capacities, into metric units with Smalley's new engineering tool. A simple conversion tool allows for units to be converted such as mass and weight, angular measurements, velocities, temperatures, pressures and densities and more. Additional engineering tools allow engineers to design custom wave springs and Spirolox® retaining rings. Custom designs can be manufactured from .200" to 120".

Hot Wheels goes military!
Mechanical Mobile Platforms (MMPs), a family of simplified, man-portable robots from Machine Lab Inc., can perform a range of surveillance and bomb-disposal tasks at a price point low enough for wide deployment. The Machine Lab engineering team started out with one overarching design principle: Keep it simple. Powered by compact, economical, high-torque motors from MICROMO, these robots are making an important difference around the world.

Mike Likes: Bond metals and plastics in seconds
Ultra Light-Weld 3013 from Dymax is a resilient, low-viscosity, moisture-resistant adhesive designed for rapid bonding to a wide variety of plastic and metal substrates. This solvent-free, worker-friendly product forms high-strength, environmentally resistant bonds for appliance assembly, bond joint and sealing, plastic window bonding, and plastic assembly. It fluoresces blue under low-intensity "black" light, allowing for in-line quality control using optical scanners. Cures in seconds when exposed to ultraviolet and visible light – even through UV-blocked plastics.

Quick Look: Extreme high-temp accelerometers
The Endevco model 6240M10 is a hermetically sealed high-temperature piezoelectric charge output accelerometer with continuous operation to +649°C (+1,200°F) and intermittent operation to +760°C (+1400°F). The high reliability of this transducer within such extreme environments makes it ideally suited for aircraft and ground gas-turbine engine vibration monitoring, as well as for exhaust and compression systems and high-temp machinery and equipment.
