Abstract: A tool container has a pair of housing members pivotally coupled with one another to provide an opened and closed position. At least one of the members defines a cavity to receive tools. The cavity is defined by a base and a wall extending from the base. A tool retaining insert is permanently secured in the cavity. The insert and wall include tenons and grooves to secure the insert in the housing member. Also, an arcuate locking mechanism is included to maintain the pair of housing members in a closed position.

Abstract: A weather resistant electrical disconnect junction box having a base member of molded insulating material with a back panel and side panels forming an internal volume with a front access opening and a cover member of molded insulating material dimensioned and contoured to removably cover the access opening with a weather resistant seal. Internal insulating terminal mounts are integrally molded with the back panel of the box and dimensioned and arranged for selectively receiving and retaining conductive terminal blocks, fuse clips and disconnect terminals in cooperative arrangement for thereby selectively providing a weather resistant fused or non-fused electrical disconnect junction box which permits easy manufacture and assembly.

Abstract: A rotary centrifuge seal consisting of a silicone rubber ring-shaped diaphragm secured to a phenolic ring member is manufactured by inserting the preformed phenolic compound element into a mold cavity of an injection compression mold with precise fit. The phenolic element is then covered with an overmold cavity and silicone rubber is injected into the overmold cavity by runnerless injection techniques in contact with exposed bonding surfaces of the phenolic compound element and the silicone rubber molding components and the phenolic compound element are compressed together to form a strong molecular bond with the application of heat and without the required use of primers, adhesives, bonding agents or mechanical bonding. The phenolic compound element is shaped in the form of a ring having external and internal peripheral surfaces whereby the exposed bonding surfaces include these internal and external peripheral surfaces to provide a more secure bond.

Abstract: A syringe plunger is manufactured by injecting polypropylene with filler into a mold for forming the hard core of the plunger, and immediately thereafter co-injecting a thermoplastic elastomer into a cover mold positioned at the forward end of the plunger mold cavity to thereby form a soft exterior cover over the forward end of the hard plunger core with a secure chemical bond.

Abstract: A tool container (20, 520, 620) has a pair of clamshell housing members (22, 24, 422, 424) hingedly coupled to be moved between opened and closed positions. At least one of the members (22, 24, 422, 424) defines a cavity defined by a base (42, 44, 442, 444) and a wall (58, 60, 62, 64, 458, 460, 462, 464) extending from the base (42, 44, 442, 444), and a two-retaining insert (32, 34, 36, 37, 431, 433) is provided in the cavity. The insert (32, 34, 36, 37, 431, 433) and wall (58, 60, 62, 64, 458, 460, 462, 464) include alternating complementary dovetail tenons (74, 132, 474, 532) and recesses (76, 134, 476, 534) secure a tool-retaining insert in the cavity of the housing member (22, 24, 422, 424).

Abstract: A syringe plunger is formed by a two-shot molding process. A hard plastic core is formed in a first mold, and the distal portion of the hard plastic core is subsequently overmolded with soft rubber. The result is a fully automated manufacturing process increasing quality and lowering costs, and a unique plunger having a hard plastic core and soft rubber exterior which are molecularly and permanently bonded together.
