Abstract: 1,056,689. Making hooked fasteners; finishing fabrics. J. BILLARANT. Nov. 17, 1964 [Nov. 29, 1963], No. 46817/64. Headings D1K and D1S. A fastener element of the interengaging- hooks type is made by corrugating nylon manofils over bars (not shown) and under bars 3, heat setting the manofils, applying and setting a layer of plastic 10, and cutting the loops. The cutters 71 rise between the bars 3, tilt into contact with the bars, and traverse along them to cut one limb of the loops. The bars 3 are carried by continuously moving chains with which the cutter mechanism is temporarily engaged so that the cutters accompany the moving bars. After a cutting stroke, the cutters resume their upright position, descend clear of the bars, and step backwards to operate on the next section of the fastener. At the stage shown, .the oppositely-facing hooks 11b have already been cut by another set of cutters mounted on the same carriage as the cutters 71 but longitudinally spaced from them. The carriage is mounted in a vertically-sliding carriage which, in turn, is mounted on a longitudinally-sliding carriage, all the movements (including tilting of the cutters) being effected by pneumatic jacks. The heads of the cutters (Fig. 5) have a flat surface 74a to slide against the bars 3, and a serrated cutting edge 74b.

Abstract: 1,171,119. Digital data storage. INTERNATIONAL BUSINESS MACHINES CORP. 21 Oct., 1966 [22 Oct., 1965], No. 47117/66. Heading G4C. [Also in Division H1] A microwave absorption element, primarily for use as a data-storage element, comprises a toroid of gyromagnetic material (e.g. ferrite) circularly magnetized in a selected direction and means for propagating microwave energy in the vicinity of the toroid whereby an amount of energy dependent upon the direction of magnetization is absorbed. As shown, an array of toroids 1a, 1b &c. is arranged adjacent a strip line 22, 38 from which microwave energy at the gyromagnetic resonance frequency of the toroids is distributed to a series of helical conductors 24, 26 &c. each arranged within one of the toroids. The helices set up circularly polarized (c.p.) waves within the toroids which are either absorbed or transmitted according to whether the direction of the remanent magnetization of the relevant toroid is the same as or opposite to the direction of rotation of the c.p. wave. The unabsorbed energy is coupled to detection circuits by means of directional couplers 32a, 32b, &c. The toroids are brought to desired states of remanence by means of axial conductors (not shown) through which currents are passed in the required directions. The pattern of remanent states of the toroids may represent one word in a memory store and the word may be read-out by a microwave interrogation pulse on line 22. The coils may be arranged on the outsides of the toroids and the latter may be axially elongated. The toroid of Fig. 8 consists of a dielectric member 100 having cylindrical ferrite inserts 104. A microwave helix 106 is printed on the outside surface of the toroid.

Inventor: CAUNT ALAN
IPC: F16F7/08
Filed: 1965-11-20
Abstract: 1,155,838. Universal movement dampers. METALASTIK Ltd. 4 Nov., 1966 [20 Nov., 1965], No. 49413/65. Heading F2S. In a universal movement damper a member 34 or 35, Fig. 2, made of rigid material, e.g. plastics, has its ball end 30, or 31 tightly fitted into a cylindrical rubber part 32 so as to form a bulge, such as 20 or 21, Fig. 1, in the wall of the part 32 the ball end 30 or 31 being universally movable and slidable to-and-fro in the cylindrical rubber part 32 so that damping work is done by sliding friction and internal hysteresis of the rubber. As shown in Fig. 1 the rubber parts 10, 11, which may differ in thickness of material and size with corresponding changes in the sizes of the ball ends 16, 17 of a dumbbell member 15, may be reinforced with woven, or braided, sleeves applied externally or, imbedded in the rubber. The ball ends 16, 17 may be corrugated or, provided with raised formations. The fitting for the cylindrical lower end of the rubber part 11 comprises a mushroom formation 24 with an air relief opening 27 and a spring clip 26, an end wall 22 of the upper part being secured by a rivet 14 having an air bore 18. As shown in Fig. 2 the ball end parts 30, 31 are mounted on relatively movable parts 13, 12 and co-operate with the single rubber sleeve 32. The ball ends may be corrugated &c., and fluted to prevent the build up of air pressure within the tube 32. The final approach of the members is cushioned by the compression of the meeting ends of the parts 10, 11, Fig. 1 and, in the embodiment of Fig. 2, by the compression of the ends of the sleeve 32, with the flange mountings of the members 34, 35. Lubrication of the rubber parts reduces the damping factor. Rubber buffering noses (40), Fig. 3 not shown, may be formed on the ball ends (16, 17) and buffering tips (41) reinforced with backing rings (42), limit the extension of the damper. In the arrangement of Fig. 1 buffering at the end of a contraction stroke may be attained by providing the parts 10, 11 with rubber end walls. In a modification of the embodiment of Fig. 2 extension of the damper is limited by part spherical ferrules on the ends of the cylindrical part 32. In a further modification a damper, as shown in Fig. 2, is mounted within a hollow, frustoconical, rubber spring and, in a still further arrangement, such a damper is incorporated in spring having two U-shaped metal members arranged one within the other with one inverted with respect to the other and having pads of rubber bonded between their overlapping vertical limbs.
