Abstract: An improved window sash lock keeper is provided having a slot to provide clearance for a burr, which is typically found on a surface upon which such a sash lock keeper is mounted. The improved keeper is typically mounted flush to a surface of an extruded window component. The clearance slot allows the keeper to be mounted with improved precision and thereby reduces interferences caused by misaligned window hardware.

Abstract: A mechanical rotary seal that produces a positive drive force so that all components of the seal rotate in unison upon a rotating shaft. The mechanical rotating seal effects a tight fluid seal between a submersible pump housing and a rotating shaft when the mechanical rotary seal is engaged with a stationary seal or element within the submersible pump housing. The mechanical rotary seal comprises a seal housing, a retainer having a seal face for engaging with the stationery seal and a coil spring between the seal housing and the retainer.

Abstract: First pumping threads are formed on an inner circumferential surface of the seal lip portion of an elastomer lip member. The first pumping threads generate a pumping action in a leakage direction when a shaft rotates. A first resin lip member is arranged at a rear side of the elastomer lip member. Second pumping threads generate a pumping action in a direction opposite to the leakage direction when the shaft rotates. The second pumping threads are formed from an inner circumferential surface of a seal lip portion of the first resin lip member to a rear portion of a bent portion thereof. A second resin lip member is arranged at a rear side of the first resin lip member and has a surface sliding on the shaft, which is formed smoothly.

Abstract: A pressure regulator uses a pliable seal to segregate a pressure confinement volume from the remaining cylinder volume. The pliable seal has a cross section comprising a pair of apexes that are disposed into grooves incorporated into the piston and the cylinder internal wall. The radii of the pliable seal establish a rolling contact to ensure pressure seal in the presence of seal deformation. The seal promotes linear regulator response and minimizes hysteresis causes by frictional forces of prior art piston rings.

Abstract: A pressure balanced floating seal system positioned within a structure about a rotating shaft. The floating seal system has a cylindrical outer seal housing having a cylindrical internal recessed region formed in the outer seal housing with a retaining flange extending into said internal recessed region. A cylindrical inner seal housing is positioned within the internal recessed region. The inner seal housing has an annular internal surface for accommodating the rotating shaft. Two sealing member retaining grooves are formed in the inner seal housing annular internal surface and a lubricant recess is formed between the two grooves. An intermediate seal is retained on the forward side of the inner seal housing forward face between the inner seal housing and the outer seal housing at the retaining flange. Sealing members are positioned in the sealing member retaining grooves at substantially the same radius as the intermediate seal.

Abstract: A non-contacting seal which includes a stationary tooth that radially overlaps a tooth on a rotatable shaft, with the sealing action resulting from controlled clearance both radially between stationary tooth and the shaft, and axially between the stationary tooth and the shaft. The seal may also be in the form of a stationary tooth that is approximately in the same radial plane as a tooth on a rotatable shaft, with the sealing action resulting from both a controlled clearance gap between the two teeth and from the momentum of liquid traveling outward from the rotating tooth making it difficult for the liquid to turn to go axially through the gap between the rotating tooth and the stationary tooth. The seal may also comprise the combination of the two seals described above.

Abstract: A door truck which has a one piece frame and plastic wheels for operation in an overhead track for supporting a door in which the wheels are mounted to the frame with barrel nuts and a threaded stud. The frame has a door supporting portion through which a pendant nut can be extended with its head mounted upwardly or downwardly so as to support a door.

Abstract: A seal assembly to be inserted between two members in relative rotation, including a bushing that is fitted to the first member and is connected with a gasket, wherein both connections form fluid-tight seals. The gasket includes a rigid reinforcement that is fitted via a fluid-tight seal to the second member and a first sealing member, which is made of an elastomeric material and provided with a first annular lip. The first annular lip contacts the sleeve-type coupling portion of the bushing, which is mounted coaxially with the first lip. The portion of the reinforcement facing the bushing is provided with a seat in which a rigid ring made of an oxidation-resistant material is mounted. The rigid ring extends in front of the flange portion of the bushing, which carries a second sealing member made of an elastomeric material. The sealing member is provided with two axially extending lips which axially and radially contact portions of the ring.

Abstract: A vehicle hood hinge includes a hinge arm contacted with a bottom surface of hood at its top surface and provided with a fitting hole and first and second hinge holes, the fitting hole being fitted into the bottom surface of the hood by a bolt, and the first and second hinge holes being formed at front and rear portions of one side of the hinge arm; first and second links being respectively fitted into the first and second hinge holes by a shaft pin at their top portions; a hinge support provided with a hinge hole at one side portion and securing holes at front and rear portions, the hinge hole being rotatably fitted to a bottom portion of the second link by the shaft pin, and the securing holes being fitted into a top surface of the vehicle at its bottom surface by a bolt; a slot longitudinally pierced in a lengthwise direction to detach the hinge pin fitted into the bottom portion of the first link from a center shaft of the hinge during an external impact; and a hinge positioning means formed in the slot t
