Patent number: 5364252Abstract: A gas injector having a retractable nozzle with linear gas feed passage therethrough for a gas assist plastics injection molding machine. The injector interfaces with the injection molding tool and has a nozzle with a tip that, in a forward position, protrudes through a port therein leading into the tool cavity or a runner system leading into the cavity for gas injection during molding. The nozzle tip is connected by a nozzle body to a base that is operatively mounted in an actuator housing. The base is connected to an in-line gas routing extension of the nozzle that projects through the outer cover of the housing. The extension is coaxial with an internal spring that seats on the base and holds the nozzle tip in a gas injection position resisting the force of plastics injection pressure.Type: GrantFiled: August 26, 1992Date of Patent: November 15, 1994Assignee: General Motors CorporationInventors: David G.

Patent number: RE33758Abstract: A vehicle body compartment is selectively closed by a spring loaded closure panel movable between an open position and a closed position. A latch assembly is mounted on the panel and has a latch bolt spring biased to an unlatched position and normally maintained in the latched position by a key releasable detent lever. A pull down mechanism includes a housing mounted on a vehicle body and a striker mounted thereon by a motorized vertically reciprocating drive unit for moving the striker between extended position and a retracted position. When the panel is moved toward the closed position, the latch bolt engaes with the extended striker to interconnect the panel with the striker. The drive unit is energized and retracts the striker, thereby pulling the panel to its fully closed position. A cam acts between the detent lever of the latch assembly and the housing of the pull down mechanism.Type: GrantFiled: September 28, 1989Date of Patent: December 3, 1991Assignee: General Motors CorporationInventors: David E.
