  • Patent number: 10464244
    Abstract: An improved injection mold for forming an injection molded component. The injection mold includes a main cavity block and a main core block that are moveable with respect to one another. The main cavity block has a cavity block mating face that includes a first mold surface and the main core block has a core block mating face that includes a second mold surface. A plurality of induction heating coils extend within the main cavity block and a plurality of gas inlet channels extend through the main core block. The second mold surface includes a plurality ridges that cooperatively form a continuous gas flow path that is disposed in fluid communication with the plurality of as inlet channels. The continuous gas flow path follows a serpentine shape to provide even and uninterrupted gas flow across the second mold surface.

  • Patent number: 8627981
    Abstract: A container (210) for holding granular or powdered material and formed by a top wall (212), a bottom wall (214), a front wall (216), a rear wall (218), a first side wall (220), and a second side wall (222). A rotatably removable lid (D) is interiorly mounted with a scoop (32) and is pivotally hinged to a collar (300) that includes a sealing gasket (330). The collar (300) mounts to the walls of the container (210). A sealing wall 240 of the lid (D) cooperates with the gasket 300 to prevent the contents from spilling. The container (210) incorporates additional sealing features wherein the gasket (330) projects inwardly from the collar (300) into an interior space (H, I) of the container (210) to be biased against the sealing flange (284). The sealing wall includes modifications that funnel powder into the interior space (H,I) of the receptacle (280).

  • Patent number: 5364252
    Abstract: 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.

  • Patent number: 5346272
    Abstract: A method and apparatus of selectively applying a holding force to a vehicle door hinge, comprises the steps of (i) determining when a vehicle door is open and, when the vehicle door is open, thereafter (ii) sensing door movement to determine if the door has remained substantially stationary in an open position for a predetermined time period, (iii) if the door has remained stationary in an open position for a predetermined time period, activating a braking mechanism to provide a holding force for the door, (iv) if the braking mechanism is activated, determining if the door has moved a predetermined distance since activating the braking mechanism, (v) if the door has moved a predetermined distance since activating the braking mechanism, deactivating the braking mechanism, (vi) sensing whether the door is closed, and (vii) if the door is closed, deactivating the braking mechanism.

  • Patent number: 5138795
    Abstract: A sliding door in a van is mounted on tracks for sliding movement between open and closed positions. At the closed position a weather strip is compressed and a door latch is latched. A cable is attached to the door and routed through the vehicle body via pulleys so that pulling the first cable end opens the door and pulling the second cable end closes the door. A motorized drive mechanism includes first and second reels mounted concentrically and having the cable ends wrapped respectively about the reels in opposite directions. A motor drives in one direction rotating the first reel to open the door and is reversible to rotate the second reel to close the door.

  • Patent number: RE33758
    Abstract: 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.
