Abstract: A method and system for restraining the top plate of ballistic cover systems used during a supercharged engine explosion is provided. The restraining system embodies bushing-pin attachment points along the periphery of the top plate for attaching the restraint straps. The attachment points may be set at an angle of incidence relative to the top plate. Each bushing-pin attachment point includes spaced apart bushings for retaining a retention pin. The retention pin is made of a material more malleable than that of the top plate and the bushings so as to absorb a predominance of the stress through the restraint straps during an explosion. Moreover, the retention pins are easily detachable from the bushings for installation and repair purposes.

Abstract: A micrometer holder is disclosed. A micrometer is a precise measuring instrument that should be protected against damage by impact and rough handling. The device disclosed herein has a pocket large enough to receive the measuring section of the micrometer and shoulders at the side of the protector extend out in front of the micrometer body. The outer sheet forming the micrometer holder is substantially longer than the inner sheet so that the holder is held in a shape to conform to the body of the wearer when the micrometer is worn on a belt so that the micrometer is held against inadvertent removal from the holder when the person leans over or the holder is jostled. The upper edge of the front of the holder is shaped to hold the rounded edge of the micrometer.
