  • Patent number: 4339856
    Abstract: An apparatus for continuous untwisting and crimping of a cloth, including, in a treating chamber, a pair of endless net conveyers spaced vertically apart and forming a gap therebetween to serve as a cloth passage. A plurality of jet pipes, each having a series of nozzles, are arranged to jet a high pressure fluid into the cloth passage. The jet pipes are provided in a zigzag up and down arrangement on the outside of the gap with the net conveyers between them. As a long knitted or woven cloth is passed continuously through the cloth passage while it receives the force of a fluid jetted zigzag from both sides, the cloth adopts a snaky or undulating state, and is stretched, beat and crumpled strongly so that the cloth is untwisted and crimped effectively.

  • Patent number: 4337557
    Abstract: Thermoplastic yarn is texturized by the known method of forwarding it in a heated condition to a crimping zone at the entrance of a stuffer chamber (7) so as to form a plug (8) of crimped yarn within the chamber and withdrawing the yarn from the other end of the plug at a speed which is related to the input speed. The improvement comprises deriving signals from the speed of the yarn plug (8) in the stuffer chamber (7) by means of a sensing wheel (11) which drives a gapped monitoring disc (13). The disc (13) operates to intercept a beam of light from a source (14) which is directed on to a photo-sensor (15). The output of the photo-sensor is supplied to an electrical controller (36) which measures the time during which light is received for each gap in the disc (13) to provide a measure of the speed of the yarn plug.

  • Patent number: 4336965
    Abstract: A legrest for a dental chair has a telescopically nested section. A cable and pulley system automatically extends the nested section from the legrest as the legrest is moved from a generally vertical position to a generally horizontal position. Bias springs return the section to its nested position as the legrest moves back towards its near vertical position.

  • Patent number: 4336871
    Abstract: In a motor vehicle clutch cover assembly comprising a cover, a pressure plate rotatable with the cover but movable axially relative thereto, and axially-acting resilient means such as a diaphragm located between the cover and the pressure plate and operable to urge the pressure plate away from the cover, the invention provides one or more retaining shims adapted to limit the displacement of the pressure plate relative to the cover, and corresponding apertures in the cover which allow the retaining shims to be removed or inserted. The retaining shims are fitted either during removal of the cover assembly for servicing, or during replacement, and by restricting displacement of the pressure plate reduce the effective axial dimension of the cover assembly thereby facilitating removal or replacement of the assembly in a confined space.

  • Patent number: 4335838
    Abstract: A molded plastic hanger and a clip for use therewith or with other members. The hanger includes a body portion having a diverging pair of arms including slots therein and a crossbar for mounting garment holding clips. A plastic swivel hook is connected to the body portion at a stem. The stem includes a shaft having an annular locking recess in its periphery which is adapted to be received within a mating socket of the hook to connect the hook and body portion to each other while enabling them to be swiveled readily with respect to each other. The clip is arranged for securement to the crossbar of the hanger or to any other rod-like element and is formed of a three piece construction comprising a pair of plastic jaws and a resilient U-shaped member, also formed of plastic, but having a higher tensile strength and resiliency than the plastic of the jaws.

  • Patent number: 4334641
    Abstract: An adjustable garment hanger comprised of four (4) main wire members, which include a support member, two extensible angle members and a connecting rod. Each of the angle members is adjustably attached to both the support member and to the connecting rod by duplex sleeve connectors. The support member includes a suspension hook portion and has formed thereon a pair of downwardly diverging legs, which form an angle substantially the same as the angle of a neck and shoulder portion of a garment. Each duplex sleeve connector is identical in construction and is substantially "S" shaped so as to form two loop portions. Each end of the diverging legs and each end of the connecting rod have one loop portion of the sleeve connector securely attached thereto so as to not allow any movement thereon. Each of the angle members are substantially "V" shaped so as to have two arm portions.

  • Patent number: 4333590
    Abstract: A garment hanger is constructed so that its width adjacent to its hook is adjustable whereby coats or other garments on the hanger cannot be squashed together and the number of garments hanging on a rack can be ascertained without counting. The adjustability enables the same number of hangers to be on a rack regardless of the thickness of the material from which the garment is made. The adjustable member may be an integral part of a new hanger or may be a separate attachment to an existing hanger.

  • Patent number: 4330909
    Abstract: An elongated knit web is flattened and guided by an apparatus having a support frame which extends longitudinally in a plane and which has an upstream and a downstream end. A pivot supports this frame for pivoting about a pivot axis transverse to the plane at the upstream end. A pair of transversely extending and longitudinally spaced spreader rollers are provided on the frame adjacent the upstream end and each has a pair of screwthread formations of opposite hand, these spreader rollers being driven to spread out the web transversely. A pair of transversely extending and longitudinally spaced guide rollers are provided on the frame between the spreader rollers and the downstream end, these guide rollers being freely rotating and having surfaces which are made to adhere to the web to prevent its edges from curling up. A control system pivots the frame about its pivot axis to position the edges of the exiting web.
