Title: A new or improved flexible shaft coupling
IPC: F16D3/56
Filed: 1944-01-26
Abstract: 574,468. Flexible shaft couplings. STIEGER, H. J. Jan. 26, 1944, No. 1495. [Class 80 (ii)] [Also in Group XXXII] A flexible shaft coupling. comprises end fittings 11 on the shafts 12 to be coupled, connected by a number of circumferentially disposed spokes 10 secured at their ends to the fittings, the spokes being formed by a bundle of metal wires 13, the effective thickness of the spokes decreasing progressively from each end towards the centre to promote uniform stressing. Each individual wire 13 may itself be tapered and the spokes may have a spring winding 14 therearound. In the centre may be a stabilizing ring comprising transverse discs 15 bonded together by rubber 16 and having holes through which the spokes pass. The coupling may be used between an axle-end 18, Fig. 3, and a wheel hub 19. The wires 13 are welded in holes in end plates 17, and have an interleaving layer of rubber 21 bonded thereto. An internal bulbous stop 33 prevents excessive deflection. When applied to a vehicle axle the usual vehicle springs are omitted. In a modification, wires 23, Fig. 6, of different lengths are secured to or bent round rings 27, 28 and are encased in a rubber sheath 24 which has a spiral winding 29 of wire or a fabric covering. Within the rubber sheath is a tube 30 which may be inflated with air or liquid to tension the wires 'and provide additional support. In another construction, Fig. 4 (not shown), a plurality of metal stabilizing rings are used, some or all of the rings projecting exteriorly from the rubber to provide a cooling surface.

Abstract: 1299191 Non woven fabric TURNER BROS ASBESTOS Co Ltd 2 Jan 1970 [10 Jan 1969] 1579/69 Headings DIP and D1R An asbestos product e.g. cloth, sliver or yarn is rendered substantially less dusty by impregnating it with a dispersion, emulsion or solution of a film-forming polymeric material having an extension at break of at least 50% and removing the continuous phase of the dispersion or emulsion or the solvent of the solution to leave polymer particles amounting to 0.1-5% of the product which bond at least the majority of the fibres at their point of contact. Examples of such polymers are polyvinyl acetate plasticised with dibutyl phthalate, vinyl acetate with vinyl coprate, 2-ethylhexyl-acrylate or an acrylate, plasticised polyvinyl chloride copolymers of styrene, and an acrylate latexes of natural rubber, styrenebutadiene rubber or neoprene. As shown, cloth 1 passes into a bath 3 of the impregnating material and through rollers 4, 5 which squeeze out excess moisture and over roller 7 in drying oven 6. In another embodiment, asbestos slivers or yarns are impregnated by passage over a damping roller which dips into a bath of an aqueous dispersion or emulsion of the polymeric material.

Abstract: 661,199. Castings ; forging - machines. STEVENS, A. H. (Clearing Machine Corporation). Jan. 28, 1949, No. 2403/49. Classes 83 (i) and 83 (iv). A machine for isolating unsound metal of an ingot comprises a die block having a recess, means for charging an ingot longitudinally into this recess, means for isolating the unsound metal, e.g. as in U.S.A. Specification 2,021,227, means for upsetting the ingot around the isolated unsound metal and means for ejecting the ingot from the die-block. An ingot 21, Fig. 3, is inserted in the recess of a liner 20 of resistant material and the die block 12 is turned by a pinion 16, Fig. 1, rack 17 and hydraulic cylinder 19 to bring the bore 22 into line with the hollow driving-shaft 9 of the turn-table 4 which carries the block 12. A die 34 is moved along the guide 38 in the press head 33 to bring it into line with the ingot and then the head is brought down hydraulically to extrude the segregate to form a projection 41, Fig. 7. Second and third dies 35, 36, also carried in grooves in the press head, are then moved into line in place of the die 34 and down to operate on the end of the ingot successively to isolate further the segregate as in Figs. 8 and 9. The block is then rotated to bring the axis of the ingot again into horizontal position and the ingot is ejected by a hydraulically-operated rod 24 into a device 42. If desired, the ingot may then be placed by the device 42 and manipulator 40, only part shown, on the face 23 and forged by a flat-faced die, also carried by the head 33, to reduce it to substantially its original form. If desired, duplicate devices 42 and manipulators 40 may be arranged at 90 degrees and the table 4 be turned through this angle after an ingot has been ejected so that while it is being transferred a fresh ingot may be inserted. Scale &c. formed during the first operations can fall down the bore 22 and shaft 9 into the pit. Instead of being operated hydraulically the devices may be operated mechanically.
