Abstract: An improved planar support structure for a planar of a personal computer system is comprised of an integral structure having a plurality of connector support frames. The planar support structure is interposed between the planar and a supporting structure and securely fastened to each. Each frame surrounds the perimeter of a corresponding connector of the expansion slots on the planar. Each frame supports a connector to prevent the connector from flexing the planar when an adapter board is inserted into the connector. Additional alignment pins associated with the planar support structure improve ease of assembly during construction of the system.

Abstract: An apparatus for electromagnetically shielding electronic equipment has a first and second spaced apart housing members having a gap between them. A rigid member having a plurality of openings is interposed between them. A spring member connected to the rigid member has a plurality of spring fingers extending through openings in the rigid member. A cover member has a cam which forces the first housing member against one side of the spring member to extend the spring finger into the second housing member in order to cause an electrical connection between the first and second housing members.

Abstract: A forms feed tractor belt includes drive members molded around a thin, flexible band at longitudinal intervals. To make the belt, slots are first punched at longitudinal intervals in at least one side of the flexible band. Drive members are then molded around the band at the slots except for at least one drive memberless interval at each end of the band. The ends of the band are overlapped so that the slots of the drive memberless intervals coincide. Final drive members are then molded around the slots of each pair of coincided drive memberless intervals to complete the endless tractor belt.
