  • Patent number: 6446697
    Abstract: Method of rapidly making casting, comprising: designing a computer graphic model of the casting; sectioning the graphic model into graphic members which are at least one of blocks and slabs; carving a solid member for each of the graphic members, the solid members being (i) constituted of a meltable or evaporative solid material (i.e. wax or polystyrene), (ii) proportional to and enveloping its corresponding graphic member, and the carving being carried out by accessing two or more sides of each solid member to at least essentially duplicate the corresponding graphic member; forming a mold around the pattern, and casting metal within the mold while removing the pattern from such mold either by evaporation during pouring of the molten metal thereinto or by melting prior thereto.

  • Patent number: 6316047
    Abstract: A method of applying a refractory coating to densified foundry sand cores having micropores between the sand grains having the steps of: (a) mixing a dry powder refractory material (anhydrous MmgOSiO2 talc) with a dry powder impacting media, the refractory material having a particle size in the range of 5-40 microns and the weight ratio between the refractory material and the impacting media; (b) fluidizing the mixture in a contained zone by introducing positive air pressure at one end of the zone and applying a negative pressure at the other end of the zone; and (c) quickly and entirely immersing the sand cores in the zone containing the fluidized mixture and substantially immediately thereafter withdrawing (without reciprocal movement) such sand cores without the need for added motion to be coated with essentially only the refractory material as impacted by the impacting media. The cores will be coated continuously with the refractory material, impacted with the micropores of the sand core.

  • Patent number: 6131341
    Abstract: A vehicle door sealing system includes a flexible weatherstrip containing magnetizable particulate material. Selected areas of the weatherstrip are magnetized to enhance the sealing action at hard-to-seal zones, such as curved corner areas along the door perimeter. The magnetic action is confined to the hard-to-seal areas so that the magnetic action will not make it excessively difficult for a person to open the vehicle door.

  • Patent number: 6129133
    Abstract: The isolator core cooperates with companion core elements in a casting operation to form a short coolant jacket surrounding the upper portion of each engine cylinder adjacent the air/fuel combustion chamber and an air pocket that surrounds the lower region of the cylinder. Drainback passage core elements may be formed integrally with the isolator core thereby reducing the total number of cores in the casting mold package during a casting operation, the finished casting thereby eliminating dividing walls between the isolator and the oil drain cores thus reducing the number of core elements and reducing the cost and complexity of the casting operation as well as reducing the weight of the finished casting. The isolator core may be used independently of cylinder liners during the casting operation.

  • Patent number: 6127629
    Abstract: A microelectronic device is hermetically sealed at the wafer level. A substrate is provided having associated electronics and at least one metal bonding pad. A dielectric layer, such as pyrex glass film, is sputter deposited atop the substrate to form a glass/metal seal. A glass film is thereafter planarized, preferably by chemical-mechanical polishing, to remove surface variations. A cover wafer is thereafter anodically bonded to the dielectric layer/glass film so as to define a sealed cavity for housing and protecting the substrate electronics. The resultant microelectronic device is packaged in its own hermetically sealed container at the wafer level.

  • Patent number: 6099048
    Abstract: An automotive door latching system can include a first latch for locking one vehicle door, a second latch for locking a second vehicle door, and an electric switch controlled by the first switch for supplying current to an electrically-operated latch release means associated with the second latch. The latching system requires that the first latch be in the door release state before the second latch can be moved to the door release state. Consequently the doors are openable only in a predetermined sequence.

  • Patent number: 6070921
    Abstract: A lift-gate dual latch mechanism utilizing both a primary spring and an auxiliary spring operates to provide the additional force needed to release a striker member from both stop positions of a dual latch. Without the auxiliary spring as mentioned above, the lift-gate, being a heavy member typically stays in the latching mechanism when the lift-gate key is actuated to the open position. This requires additional lift forces, such as added springs between the lift-gate and the back panel of the vehicle to open the lift-gate from the mandated second lock position. Gas cylinders are shown to assist the opening of the lift-gate when required.
