  • Patent number: 5944364
    Abstract: Live swivel coupling device has a hollow first housing and a hollow second housing, each of which is open on opposing ends in a main axial direction. The first has a generally radially symmetrical inner surface, an indentation in the inner surface, and an internal, gasket-holding extension; the second has a generally radially symmetrical outer surface to relate with the inner surface of the first housing and an indentation in the outer surface. The indentations are for retaining the rotatable bearing set when the first and second housings are coupled. At least one rotatable bearing makes up a rotatable bearing set which also serves as a retaining device to hold the housings together in the main axial direction when the housings are coupled.

  • Patent number: 5941537
    Abstract: A static seal includes first and second spaced apart walls having a gap therebetween for channeling a pressurized fluid. The first wall includes a recessed seat facing the second wall defined by spaced apart first and second faces joined together at a base. A seal insert is loosely disposed in the seat and is trapped therein by the first and second faces. The first and second faces are shorter than the insert to project a top of the insert above the seat and below the second wall for initially promoting flow of the fluid over the insert top to deploy the insert in abutting contact with both the second face and the second wall to seal the gap.

  • Patent number: 5941654
    Abstract: A bus bar panel system utilizes a quick acting and simplified fastening system for making connections. The bus bar is preferably pre-perforated along the edges, although holes may be drilled at the time of fastening. The fastening system uses a stud having threads on one end for receiving the usual washers and nut. On the other end, usually away from the installer, the stud is provided with flats which engage an open slot or yoke on a keeper clip. The clip has a gauge flange to engage the edge of the bar or clamp through which the stud extends. The transverse dimensions of the open slot are related to the flats and the length of the slot to the distance of the perforations from the edge of the bar. The clip also includes a spring section which grabs the end of the stud holding the clip in place so that the installer has both hands free to secure the nut and washers.

  • Patent number: 5938207
    Abstract: A rod seal system having a pair of rod seals that form a buffer area between a high pressure area containing working gas and a low pressure area of a heat engine, such as a Stirling cycle engine. A pump that becomes passively charged with working gas at relatively low pressure and which releases working gas at relatively high pressure when actuated is used to force working gas from the buffer area to the high pressure area through a conduit. The working gas may be hydrogen gas and the pump may be a metal hydride pump that is thermally actuated. The low pressure area may contain air and lubricant at atmospheric pressure. A system for separating the lubricant collecting within the buffer area and reintroducing the lubricant into the low pressure area can also be incorporated into the rod seal system.

  • Patent number: 5938368
    Abstract: By providing a locking member having collapsible and bendable arm members which cooperate with a head-bearing fastening member, a unique fastening system is achieved which enables hardware products, such as handles, knobs, locks, brackets, and the like to be easily and quickly mounted to any desired furniture product. In the preferred embodiment, the head-bearing fastener and the locking member are constructed to be axially inserted through the mounting holes formed in the furniture product. Then, by mounting the fastening system to the hardware product and inserting the mounted fastening system through the mounting holes, the hardware product is quickly and easily securely affixed in position as the collapsible and foldable arm members of the locking member are forced outwardly into an overall width greater than the mounting holes during the threaded advance of the fastener with the hardware product.

  • Patent number: 5934818
    Abstract: A screen connector for engaging a cable, including an uncovered cable screen, positioned on a plate member is disclosed. The screen connector includes a clamp clip having at least two clamping legs which are spring-mounted relative to one another. The legs of the clamp clip encompass the plate member or busbar by lying opposite one another on the outside, whereby they engage the busbar from below, preferably by a coupling hook. The screen connector also includes a guide press piece having an outer and inner guide surface which slides along outer and inner guideways of the clamping legs when the guide press piece is moved to enclose the clamping legs. The guideways are shaped on the clamping legs in such a way that the clamping legs can be spring-mounted relative to one another when the guide press piece is in an upper initial position, and consequently can be locked onto the busbar in a perpendicular direction to the upper side of the busbar by means of their coupling hooks.

  • Patent number: 5934686
    Abstract: A seal arrangement provides a reliable and durable seal even around a protruding edge or corner of a rim of a first component that is connected to a second component, for example the rim of an oil pan that is connected to the rim of a crankcase and the rim of the housing of an equipment mount of an internal combustion engine. An angular edge is formed at the intersection of a first sealing surface between the oil pan and the crankcase and a second sealing surface between the oil pan and the equipment mount housing. First and second grooves extend in skew directions and offset from one another along the first and second sealing surfaces, and an offset recess extends along and in the direction of the intersection edge to interconnect the first and second grooves. A rubber-elastic seal member includes major portions received in the grooves and an offset portion received in the offset recess. The seal member is press-sealed against facing complementary surfaces.

  • Patent number: 5927727
    Abstract: A sealing element, particularly for shut-off and regulating valves, comprising a tabular, piston-shaped or spherical shut-off body of a ceramic material having a hard material layer containing carbon and silicon applied to a sealing surface of the shut-off body by plasma chemical vapor deposition or plasma polymerization, in a coating chamber. The hard material layer comprises a bonding layer component applied to the sealing surface of the shut-off body and a subsequent sliding layer component. The carbon-containing bonding layer component has a first silicon content favoring adhesion to the sealing surface of the shut-off body and the subsequent carbon-containing sliding layer component having a second silicon content lower than that of the bonding layer component to achieve low coefficients of sliding friction and static friction.
