Liquefiers Patents (Class 184/98)
  • Patent number: 6142258
    Abstract: A solid lubricant tool for applying solid lubricant to the surface of a component is produced by compressing a mixture of powdered solid components under a pressure of at least about 30 kg/mm.sup.2 without application of heat to form unitary conglomerated lubricating element. The powdered solid components and processing are chosen such that the lubricating element has hardness as measured according to the Brinell scale (HB) of less than about 20. Preferred compositions include between about 5% and about 10% powdered graphite, and at least about 10% powdered tin, by weight. The tools may be used interchangeably with machining tools in standard machining equipment.

  • Patent number: 6109394
    Abstract: An extendable boom for a material handling device includes a first boom section for connection to a support frame, the first boom section having a plurality of first structural members. A second boom section is slidable with respect to the first boom section, for supporting a load to be moved and carried. The second boom section has a plurality of second structural members. Wear pads are positioned between the first and second structural members, the wear pads being a cast polyamide material with oil impregnated therein and subjected to dynamic compressive loading condition characterized by a PV value between 26,400 and 32,000. A method to manufacture the extendable boom is also claimed.

  • Patent number: 5581048
    Abstract: A shielding gasket is disclosed which may be installed between a door panel and an enclosure containing electronic equipment therein, the shielding gasket providing excellent electromagnetic shielding effectiveness in the space between the door panel and the enclosure. The shielding gasket includes a retaining medium for holding a corrosion-inhibiting fluid, which is bled from the retaining medium onto the outer surface of the conductive gasket over an extended period of time to provide a protective film over the interfacing dissimilar metals of the shielding gasket and the enclosure. The shielding gasket may include an elastomeric gasket to provide a moisture-proof seal, or a rigid metallic strip to support the shielding gasket.
