Abstract: A drive pulley for a continuous conveyor includes an inner drum and a traction drum disposed along an outer peripheral surface of the inner drum. The traction drum has a thickness in a radial direction relative to the axle that is subject to wear during driving contact between the traction drum and a conveyor belt. At least one sensor is embedded in the traction drum. The at least one sensor has an outer wear surface that coincides with an outer surface of the traction drum. The at least one sensor is configured to wear such that the outer wear surface of the at least one sensor is adapted to wear at a same rate as the outer surface of the traction drum. The at least one sensor is configured to generate a wear signal that is indicative of wear of the traction drum.

Abstract: A torque-limited fastener turnable in fastening and loosening directions for one-time use includes a fastener head with a base, a set of lugs extending from the base, and an optional set of ramps extending from the base. The lugs include abutment surfaces facing a fastening tool slot recess that receives a fastening tool. When the fastening tool is turned in the fastening direction it bears against the lug surfaces. The lugs shear off or plastically deform into recesses when the fastening tool applies a limiting fastening torque. The ramps have abutment surfaces facing a loosening tool slot recess that receives a loosening tool. The ramps cam the fastening tool over the ramp abutment surfaces if the fastening tool is in the fastening tool recess and is turned in the fastening direction after the lugs have sheared off or have plastically deformed in response to application of the limiting torque.

Abstract: An electronic connector latch system provides safety via an internally hidden latch that requires a correctly sized pin to open. The described system is positive, in that it provides a “deadbolt” style latching wherein the pull out force is perpendicular to direction of opening the latch, and latching occurs on both sides of the locking post. The system is still user friendly in that mating the two connectors together can be accomplished without any tools. Mating is achieved with a simple insertion of the mating connector. The latch is captured inside the plastic unit housing, and a stamped sheet metal spring provides high cycle life.
