Abstract: A sealing device primarily for sealing off a slit-shaped space between two radially extending surfaces arranged about a shaft and axially displaceable relative to each other along the shaft includes a first sleeve-shaped seal part and an elastically resilient sealing body. The first sleeve-shaped part forms together with the shaft an axially open space facing the cooperating surface. The elastically, resilient sealing body has in an uncompressed state a cross-sectional area and/or a shape deviating from the area and/or shape of the axially open space. The sealing body when subjected to axial forces causing the sealing body surface and the cooperating surface to abut each other is compressed sealingly between the axial space and the cooperating surface, thereby creating a sealing engagement against the entrance of the slit-shaped space and against the shaft.

Abstract: A mechanical end face seal includes one seal ring having two elements, a seal face extension portion immediately adjacent a sealing face and a seal ring body removed from the sealing face. Each of the ring elements has a radial outer diameter dimension and a radial inner dimension. The seal face extension portion is defined by an annular gap separating the seal ring body from the seal face extension portion. The annular gap opens out onto the high-pressure side of the seal. The axial thickness of the seal face extension portion is much smaller than the radial dimension of the sealing face. The seal face extension portion is connected to the thicker seal ring body by means of a thin connecting “neck”, which has a small radial dimension than the radial dimension of the sealing face. Preferably, the radial dimension of the neck has a ratio relative to the radial width of the ring sealing face between about 0.10 to about 0.70, more preferably about 0.25 to about 0.60, and most preferably about 0.

Abstract: A wall door stop includes a pin extending from the wall-facing surface. When installed on a wall exterior, the wall door stop may be attached by a regular or security screw to the wall. The pin engages a mating hole in the wall and inhibits unauthorized removal of the wall door stop through rotation and simultaneous pulling of the decorative ring. The pin engages the wall to prevent rotation of the decorative ring.

Abstract: A sealed, rotatable shaft assembly includes a housing that defines a bore that extends from an area exterior to the housing to an area interior to the housing. A shaft is rotatably disposed in the housing about an axis of the bore. The shaft extends through the bore between the interior area and the exterior area. An annular lip seal is disposed in the bore and is attached to one of the shaft and the housing. The lip seal extends from the one of the shaft and the housing to the other of the shaft and the housing in a contact seal so that rotation of the shaft with respect to the housing wears the lip seal to form a zero-clearance non-contacting seal. A labyrinth seal stage extends between the shaft and the housing. The labyrinth seal stage is disposed outward of the lip seal, with respect to the interior area and in communication with the lip seal.

Abstract: The present invention provides a piston ring structural body composed of an outer ring continuously formed of a resinous material, an inner ring continuously formed of a resinous material and a ring tensile force applying member for pressing the outer ring radially outwards via the inner ring. The piston ring structural body has a construction wherein the outer ring continuously formed of polyimide is pressed outwards in the radial direction of the piston by a coil expander via the inner ring continuously formed of PTFE. A sliding face of the outer ring, which slides on a cylinder wall, is divided into upper and lower sliding faces, whose respective upper edge portions are provided with chamfers. A contact portion of the inner ring that contacts the coil expander is provided with an upper inclined face extending inwards and upwards and a lower inclined face extending inwards and downwards. The angles of inclination of the upper and lower inclined faces range from 30° to 60°.

Abstract: The present invention provides an ambulatory assistance device such as a grab bar or the like which pivots between a non-in-use and an in-use position. The pivoting of the device is assisted by a torsion member acting between the base member and the body. The torsion device is selected so as to retain the body in its non-in-use position when placed in that position. The weight of the pivoting body of the present invention overcomes the force generated by the torsion member when the body is placed in the in-use position so as to retain that orientation. Moreover, the torsion member acts to assist the user of the device in counteracting the weight of the pivoting body member when the body member is moved between the non-in-used position and the in-use position.

Abstract: A refrigeration sealing system for a refrigeration unit includes a trap-process tube coupled with and in communication with a compressor of the refrigeration unit for receiving refrigerant from a refrigerant source. The trap-process tube defines a passageway through which refrigerant flows from the refrigerant source to the compressor. The refrigeration sealing system for a refrigeration unit further includes an annular plug disposed within the passageway. The annular plug defines a bore for facilitating the flow of refrigerant through the passageway. The annular plug is further deformable to seal the passageway of the trap process tube.

The leg regions are adapted to contact each other and to provide a restoring force when the sealing ring is compressed. A first bend connects one of said leg regions to the curved region, and a second bend connects the other of the leg regions to the curved region.

Abstract: A downhole packer in a well removably seals an annular space between an inner tube and an outer tube or well casing in a well bore. The packer provides a metal to metal tapered seal between a female sealing element having a tapered inner sealing surface and a male sealing element having a tapered outer sealing surface. Each sealing element has tubing welded to upper and lower faces as required to provide a resealable annular space that may be filled with corrosion resistant fluid under pressure. The pressure is then monitored to detect leaks. Repairs may be made by lifting out the tube, repairing the leak, and lowering the tube until the two sealing surfaces mate.
