Title: Improvements in roots blowers
Inventor: DUNLOP JOHN HENDERSON
IPC: F04C18/08
Filed: 1959-09-25
Abstract: 891,017. Roots blowers. WADE ENGINEERING Ltd. Dec. 28, 1960 [Sept. 25, 1959], No. 32735/59. Class 110 (2). In a Roots blower, the seal 23 between the rotors is formed by successive pairs of flanks 12, one flank of each pair being coated with fibres 22 perpendicular to the surface, and the other flank of each pair being uncoated. In the drawing, all the coated flanks are on rotor 2, though as an alternative, half the flanks on each rotor may be coated, so that only metal-tocoating contact occurs, that is, all the trailing flanks, or all the leading flanks of both rotors may be coated. In the embodiment, the tips 14 of one rotor do not touch the valleys 16 of the other rotor, and so coating is not needed there. The cylindrical surfaces 24, and end faces of the housing 18 may also be coated. The fibres which form the coating are preferably applied by electrostatic deposition. Specification 687,442 is referred to.

Title: Improvements in or relating to the production of stiffened fabrics and fabric articles
IPC: D06M17/02
Filed: 1935-11-27
Abstract: 466,562. Compound fabrics. BRITISH CELANESE, Ltd. Nov. 27, 1935, No. 32874. Convention date, Dec. 1, 1934. [Class 140] A stiffened compound fabric suitable for wearing-apparel, e.g. for collars, cuffs, fronts, &c. of shirts, hats, and parts thereof, and linings, is made by uniting under heat and pressure an assembly of two or more superposed fabrics comprising an outer layer containing filaments or fibres of a thermoplastic organic derivative of cellulose, and an adjacent layer containing a thermoplastic organic derivative of cellulose and a plasticizer therefor, the union being effected in the presence of water but in the absence of liquids (other than the plastizizer) having solvent properties for the organic derivative of cellulose. Alteration of the outer cellulose derivative fabric in texture or appearance is thus minimized. The outer fabric may be made solely from cellulose derivative yarns or may contain also non-thermoplastic yarns such as cotton. It may be knitted, netted, or a woven fabric e.g. a taffeta, satin, plush, or velvet. The layer containing the plasticizer may be formed wholly or partly of cellulose derivative yarns, or may be a non-thermoplastic fabric coated or impregnated with a solution or aqueous suspension of cellulose derivative. The plasticizer may be incorporated in the spinning solution from which the cellulose derivative filaments are formed, or the fabric may be treated with a solution of the plasticizer e.g. in benzol, and allowed to dry. The assembly to be hot-pressed may consist of a fabric containing cellulose acetate and a plasticizer and one or two outer fabrics containing cellulose acetate yarns, or an assembly of six or seven layers having a cellulose derivative and a plasticizer in at least each alternate layer, and one or both outer layers containing cellulose derivative yarns. For example, a woven taffeta fabric of cellulose acetate is padded with its own weight of dibutyl tartrate and is covered on both sides with fabric consisting wholly of acetone-soluble ce.lulose acetate. The assembly is cut to shape and sewn e.g. into a cuff or collar, wetted on both sides with water and hot-ironed or calendered to form a stiffened fabric. Water-soluble or water-insoluble plasticizers or high-boiling or non-volatile solvents may be used, dimethyl and dibutyl phthalate, diethyl and dibutyl tartrate, and triacetin being specified. Cellulose formate, acetate, propionate, and butyrate, and ethyl and benzyl cellulose are suitable cellulose derivatives. The assembly may be wetted with water' before hot-pressing, or steam may be injected during the pressing operation. Heat and pressure may be applied locally by devices having a pattern or design embossed thereon, or the plasticizer may be applied locally, to give local union of the fabrics. Specifications 460,232, 460,523, and 462,242 are referred to.

Abstract: 506,524. Stuffing - box substitutes. HURST, W. F. F. MARTIN-, and PACKLESS GLAND CO., Ltd. Nov. 29, 1937, No. 32958. [Class 122 (v)] The working parts are carried by a tubular guide member 4 fixed to the casing 3 by bolts 5. A sleeve 7 slides in the part 4 and has a head 8 which is a sliding fit therein. A pin 10 received in a slot 11 prevents relative rotation of tho sleeve. A carbon &c. block 12 is fixed to the head 8 and is pressed against a seating ring 2a on the part 2. A fluid-pressure operated cup-leather 14 is fixed to the part 4 and engages the sleeve. 7. Alternatively a synthetic rubber ring may be used. The spring engages a metal ring 15 supported by a flanged metal ring 16 which bears on the cup-leather 14. The diameter of the sleeve where it passes through the ring 14 may be so chosen in comparison with the diameter of the ring 12 that the fluid-pressure assists or opposes the spring pressure on the ring 12.

Title: Improvements in thrust bearings and like machine elements
IPC: F16C17/06
Filed: 1921-12-08
Abstract: 172,955. Michell Bearings, Ltd., (Assignees of Michell, A. G. M.). Dec. 15, 1920, [Convention date]. Thrust bearings.-To obtain pressure-film lubrication in thrust bearings, screw-and-nut gearing, &c., the coacting surfaces are made of slightly different curvatures so as to form tapering interspaces, one of said surfaces being generated by a line nearly but not exactly at right-angles to the axis of rotation. Fig. 1 shows the application to a simple thrust block. The thrust collar 1 is slightly convex and bears against stationary plane shoes 3 mounted on a block 5 seated spherically in a frame 4, the shoes being retained by a ring 6. The upper surface of the block 5 is slightly concave, corresponding to the surface of the collar 1. If motion is in one direction only, portions of the working surfaces of the blocks may be removed at the leaving ends. In a modification the shoes are supported on a circular rib formed on the block 5. Fig. 8 shows the invention applied to a screw-and-nut mechanism. The screw 10 has two threads 11, 12, the lines of intersection of the working surfaces of the threads with an axial plane being slightly inclined so that these surfaces have a slight convexity. The nut 13 has internal threads 15 having the same inclination as the threads 11, 12 and having similar helical surfaces, and is formed in valves. Blocks 3, supported on the threads 15, are cut from a helical strip 14, Fig. 10, which has a smaller inclination than the threads and a working surface 14<a> either square to the axis or having a smaller inclination thereto than the surface of the threads, so that the screw-thread and blocks have coacting surfaces of differing curvatures. The strip 14 may have a rib 14<c> on its lower surface. Pins 16, Fig. 11, are inserted in holes in the threads 15 to prevent motion of the blocks, and spacing-members 17, which may be integral with the blocks, are inserted between the blocks.

Title: Tapered spring reverberation delay line
IPC: G10K15/10
Filed: 1965-08-02
Abstract: 1,121,135. Reverberation systems. D. H. BALDWIN CO. 2 Aug., 1965 [18 Sept., 1964], No. 33019/65. Heading H4R. Delay device for a reverberation system comprises, Fig. 2, a spring 12 having tapered end sections mounted between input and output transducers 10 and 20, respectively. A signal applied to the coil of the input transducer imparts a torsional vibration to the annular permanent magnet 22 which vibration is coupled to the spring at 14. The torsional vibration. which is transmitted non-dispersively in the spring, is changed to a dispersive transverse vibration at a point in the tapered portion of the spring where the turn length of the spring is equal to a quarter wavelength of the torsional vibration of the spring. The transverse mode propagates to a corresponding point in the taper at the other end of the spring, where it is converted back to a torsional mode to be detected by the reproduce transducer 20, and also reflected by the mismatched termination to provide multiple delays. Due to the frequency dependent position of the mode change, and the dispersive transmission in the transverse mode, the delay produced by the device is dispersive, which is said to be desirable to avoid abrupt periodic reflections and severe flutter. The transducer hooks 18 and 19 are of low compliance, e.g. seamless tubing of cold drawn " Monel " (Registered Trade Mark), secured to the supports 30 and 32 by high compliance support wires 23, e.g. of small diameter beryllium copper or phosphor bronze, with vibration dampers 24 of butyl rubber. Fig. 7 shows the method of connecting the delay device 92 in the reproducing change of a source 85, e.g. an electronic musical instrument, phonograph, or tape recorder.
