Abstract: A improvement to a gasket that includes an elongated seamless tubular member formed from at least a plurality of interwoven glass fiber yarn ends and a plurality of spring clip fasteners spaced along the tubular member, each fastener including a base located within the tubular member and an engagement portion extending outwardly through the tubular member away from the base. The free ends of the tubular member are coupled together at a joint so that the elongated tubular member forms a closed loop. A second tubular member is positioned around the joint, concealing the joint. The second tubular member may include one or more fasteners each having a base located between the elongated tubular member and the second tubular member and an engagement portion extending outwardly through the second tubular member away from the elongated tubular member. The second tubular member may be composed of at least a second plurality of glass fiber yarns interwoven together or a corrugated metal tube.

Abstract: A leaf seal assembly is secured to the trailing edge of a shroud segment for sealing between the shroud segment and the leading edge side wall of a nozzle outer band. The leaf seal includes a circumferentially elongated seal plate biased by a pair of spring clips disposed in a groove along the trailing edge of the shroud segment to maintain the seal plate in engagement with the flange on the leading edge side wall of the nozzle outer band. The leaf seal plate and spring clips receive pins tack-welded to the shroud segment to secure the leaf seal assembly in place.

Abstract: The invention concerns a joint, the ends of which (330) comprise means (333) which can be removably fitted into one another so that they can be mutually attached to or detached.

Abstract: An adjustably sizable ring seal includes a monolithic ring having a first end portion and a second overlapping end portion. The first end portion has a first cross-section and the second end portion has an integrally formed reduced cross-section slidably receivable generally within the first cross-section and/or an integrally formed radially offset cross-section slidably receivable generally within the first cross-section so that the monolithic ring seal is circumferentially expandable and contractable in size.

Abstract: A gasket especially adapted for use as a speaker ring is provided. The gasket is formed of a plurality of segments, each having first and second ends defining first and second complementary mating surfaces respectively. The complimentary mating surfaces allow the segments to be placed end to end with the first mating surface of a segment abutting the second mating surface of an adjacent segment. All of the segments arranged together in this manner form closed gasketed ring. The first mating surface of each segment is made up of first and second relatively flat shoulders adjacent the inner and outer sides of each segment respectively, and a triangular projection extending between the first and second shoulders. Similarly, the second mating surface of each segment is made up of third and fourth relatively flat shoulders adjacent the inner and outer sides of each segment, and a triangular recess or notch extending between the third and fourth shoulders.

Abstract: An apparatus for manufacturing a large-diameter gasket in which a pair of holding presses have press members which selectively bears against an elongate band while a bending press pivots against a portion of the band. The drive press bears against a portion of the band, and with the holding presses released, moves longitudinally to move a next portion of the band into the bending press. A method of manufacturing the large-diameter gasket is disclosed, together with a jig for applying a patch of sealing material to a joint formed between opposing distal ends of the gasket.

Abstract: A seal includes a seal ring with a circumferential split defining a gap. An arcuate bridge extends across the gap and nests in the seal ring. The bridge includes an anchor end which engages the seal ring solely in friction to restrain differential circumferential movement therebetween. The bridge also includes a slip end engaging the seal ring on an opposite side of the gap with less friction than the anchor end to permit differential circumferential movement therebetween.

Abstract: A protective constant velocity (CV) joint boot having a tubular body with end openings and one longitudinal seam running from one end opening to the other enables rapid replacement of existing monolithic CV joint boots. Additionally, reinforcement of the tubular body of the protective boot against stresses caused by movement of the joint is accomplished through the use of a pair of sealing sleeves, also having seams, which are fitted under the tubular body of the protective boot. The edges of the seam of the tubular boot interlock with, as seen in cross section, an arrow head shaped male member on one edge of the seam which locks past a pair of nubs on a female retaining edge of the seam. The seams of the sleeves are off-set with the seam of the tubular body of the protective boot, thus accomplishing a more effective seal. Both sleeves have a flange that lends strength to the crests nearest the ends of the protective boot, which under most driving conditions receive more stress than the central portion.

Abstract: The low pressure seal arrangement for sealing a space defined by an inner diameter of a pipe and a rod slidably disposed with the pipe. The low pressure seal includes a sealing insert of reusable, noncorrosive, shape retentive, resilient, boron-resistant, flexible polymeric resin with an axial passage for receiving the tubular rod. The sealing insert combines the functions of a gasket and a stopper, the sealing insert having a hub end of a larger diameter than the pipe, preventing the sealing insert from slipping into the pipe. The sealing insert is installed by hand without tools and resists a pressure of at least 350 psi. The sealing insert may be removed and reused, reducing the amount of radioactive waste generated by the nuclear reactor.

Abstract: A replacement split boot assembly for a constant velocity joint on a vehicle is provided with slip-fit, non-threaded fasteners. The split boot body has pairs of opposing tabs across a longitudinal slit. Each of the tabs has a hole. The slip-fit, non-threaded fasteners have a head on one end and a radial projection spaced a distance from the head on the shaft. The fasteners are adapted to be urged through the opposing tab holes on the split boot body until the pair of tabs is located between the head of the fastener and the radial projection on the shaft. A retainer is used to lock the tabs between the head of the fastener and the retainer by urging the retainer over the radial projection of the fastener.

Abstract: A ceiling fan housing includes a cylindrical member having an upper and outer peripheral flange and a cover having a lower and outer peripheral flange. A disc includes an upper and a lower surfaces each having a peripheral groove for engaging with the peripheral flanges of the cylindrical member and the cover. The disc is made of shock absorbing material for absorbing shocks and vibrations that may be generated in the ceiling fan. The disc includes two or more curved members secured together by ribs and slots so as to form the disc.
