Abstract: 790,874. Laminates. CLARK-CUTLERMcDERMOTT CO. Nov. 25,1955, No. 33860/55. Class 140. A vibration absorbing pad 1 having a laminated structure comprises layers 2 to 6 of highly compressed needled fabric which are impregnated with vinyl plastic composition, such layers being permanently bonded together by the vinyl plastic composition and some of said layers, e.g. 3 and 5, having a filling of ground cork. The pads may be provided on one or both sides with ribs 28 of vinyl plastic composition substantially free from fibrous material which may be formed in crossing relationship as shown. Layers of filled and unfilled fabric are preferably alternated throughout the laminate. The needled fabric is preferably composed of sisal fibres needled to a textile backing. The pads are impregnated for example by being passed through baths of polyvinylchloride or copolymers of polyvinyl chloride and polyvinyl acetate ground to a powder and dispersed in a plasticizing oil with or without the addition of clay filler. The ribs are formed when the vinyl plastic composition is cured by pressing and heating between grooved platens of a press when the excess of vinyl resin in the pads exudes into these grooves.

Patent GB-342727-A (GB)
Abstract: 342,727. Curling yarns. ROBERTS, J. and MICKLETHWAITE, W., Crosland, Moor Mills, Huddersfield. Nov. 6, 1929, No. 33707. [Classes 120 (ii) and 120 (iii).] In apparatus for curling yarns, a frame c, Fig. 1, rotatable about a longitudinal axis, carries a bobbin-driving drum g rotated on an axis transverse of the frame by a slip clutch and gears i, i2, i<4>, coupled with a gear i<5> fixed to a stationary shaft k aligned with the frame axis, the bobbin m being slidable along the frame and frictionally engaged with the surface of the drum by the pressure of springs o. The yarns pass from a bobbin p in a frame p<1> driven by friction discs p<2>, p<3>, preferably of adjustable ratio, through a tube u rotating with the frame p<1>, and provided with a bar to prevent twist running back to the yarn on the bobbin p, through a horizontal eye and between horizontal and vertical tension bars, and through a device as shown in Fig. 4, wherein the last vertical tension bar s<1> moves against the spring t<3> should the twist in the rope become excessive owing to slipping of the clutch of the friction drum g. The rope passes through a tube u journalled and slidable in a bearing b<1> of the frame c and having an eccentric part u<6> for traversing the rope along the bobbin m. The tube u is rotated from the bobbin shaft by gears u<1>, u<2>, a cam u<7> on the tube engaging a roller u<8> on the frame c so that the gear u<1> of the tube u moves relatively to the gear u<2> at the ends of traverse, thus accelerating the rotation of the tube. A stop motion operating on breakage of the rope may be provided. When the fibres to be curled are in the form of sliver the bobbin p may be replaced by a can, from which the sliver is withdrawn by rollers. The Provisional Specification describes also an arrangement wherein a slip clutch under the increasing compression of the springs applies an increasing braking effect on the winding- bobbin.

Abstract: 772,372. Electromechanical filters. COLLINS RADIO CO. Nov. 26, 1954, No. 34369/54. Class 40 (8). [Also in Group XL (c)] A repetitive signal, e.g. carrier wave of 455 kc/s., is separated from random interference by an averaging process in which two portions of the signal with relative delay are respectively applied to fixed electromagnet coils 49, 53 and an adjacent coil 26 mounted on a rotatable spring-controlled shaft 17, so that the angle of deflection # is dependent on the amplitude only of the repetitive signal, due to the multiplication involved and average integration arising from the mechanical inertia of the shaft. Also a delayed or otherwise portion of the signal is applied to a further pair 56, 59 of coils so that a further coil 27 adjacent the coils 56, 59 derives an output dependent on the amplitude of the signal. A damping ring 26 on the shaft coacting with adjacent permanent magnets 47, 48 damps out vibrations of the shaft. The delay means may be a mechanical filter as described in Specifications 722,664 and 723,198, [Group XXXVI]. To avoid at certain frequencies no rotation and output from the shaft, dependent on the delay, since the output is also dependent on the relative phase of the inputs to the fixed coils 49, 53 and rotatable coil 26, part of the delayed input to the coils 49, 53 may be passed through a 90 degrees phase shifter and fed to the stationary coils of a second mechanical unit whose output is additively combined with that of the first unit (Fig. 2).
