  • Patent number: 5002842
    Abstract: A support assembly, including an end plate, for use in metal gas cells. The support assembly inhibits a plate stack which is positioned within a pressure vessel from impinging the walls of the pressure vessel. The support assembly comprises a first and a second weld ring and a first and a second end plate, each of the end plates being attached to a different end of the plate stack. The first and second weld rings mate with the first and second end plates, respectively, and cooperate to support the plate stack. The end plate comprises two plates secured together. A raised portion on one of the plates forming the end plate has a radially extending embossment formed therein to increase the rigidity thereof. The pressure vessel is constructed of generally cylindrical container defining two circumferentially extending lips, each of which is secured to an end portion.

  • Patent number: 4926909
    Abstract: A fitting for installing on the terminus of large scale industrial hoses and method of making it and installing it, in which two annular steel rings are welded onto a cylinder formed of expanded metal, which subassembly is then mounted over an extruded rubber tube and is then wrapped with a friction layer of rubber, a braided textile reinforcement layer, steel cable reinforcement, and a wrapped or extruded rubber outer cover. A hump is built up over the annular ring welded on closest to the end of the expanded metal cylinder, and a flange is then butted up adjacent to this hump to effect installation of the end of the hose. During curing, rubber freely flows through the expanded metal cylinder, securely embedding the fitting within the hose.

  • Patent number: 4904551
    Abstract: A ceramic seal assembly for electrically insulating and hermetically securing a terminal to a housing through which the terminal extends. The housing contains a fluid at a high pressure and an electrical device to which the terminal is connected. An adapter is provided for hermetically securing the seal assembly to the housing. The adapter comprises a generally tubular member defining two end portions and a collar secured to one of the two end portions. The seal assembly and housing are hermetically secured to the tubular member at separate locations. The seal assembly contains at least one annular ceramic member and is oriented such that the high pressure fluid contained within the housing causes the annular ceramic member to be in compression and thereby maintain a seal between the terminal and the housing.
