Patent GB-348216-A (GB)
Title: Improvements in the manufacture of moulded articles
IPC: B29C37/00
Filed: 1930-02-15
Abstract: 348,216. Building materials. WEITZEL, R., 23, Avenue Duquesne, Paris. Feb. 15, 1930, No. 5093. Convention date, Feb. 22, 1929. Drawings to Specification. [Class 20 (ii).] Parts of telephone cabinets &c. are made by preparing a mould, coating it with a substance preventing adhesion and then with several coats of lacquer, paint, or sizing. These are then covered with a number of layers of cloth impregnated with a product adapted to harden in the air. For example, the inner surfaces of the mould are coated with lacquer and then with a size or a fatty substance, for example, linseed oil, a mixture of turpentine, gum resin, and a siccative. The surface of the mould is rubbed smooth and coated with silica jelly. Lacquer paint (largely acetate of cellulose dissolved in acetone) is sprayed on the mould, and there is then applied to the mould a layer of fine cloth prepared with cellulose varnish, or a coating of linseed oil, benzine, and gum. When this layer is dry, several layers of cloth are applied; these are previously coated with hardening-substances, such as plaster, cement, glue, &c. When the structure is dry, it is removed from the mould, and polished.

Title: Improvements relating to dynamos for use with lighting and starting devices upon motor vehicles
IPC: B60R16/023
Filed: 1920-02-19
Abstract: 144,997. Grimaud, J. R. P. E. F. M. June 13, 1919, [Convention date]. Turning-gear.-A dynamo 1 for starting, lighting, and ignition purposes is connected to a shaft by epicyclic or differential gearing controlled by an electro-magnetic clutch providing two independent engagements, one positive and one frictional, for the purpose of varying the gear ratio between the armature shaft and the engine shaft. In the form shown, the transmission gearing, the contact-breaker 14, and the distributor 11 are enclosed in the dynamo casing. A pinion 2 on the armature shaft engages a toothed casing 3 carrying pinions 4, 5 in engagement with pinions 7, 6 on a main shaft connected to the engine shaft. The pinion 7 is fixed on its shaft, and the pinion 6 is free, but is normally held in clutching engagement with the pinion 7 by a spring 20, so that the casing 3 and enclosed gearing turn as a whole when the engine is running. At starting, an electro-magnet 9 is energized and attracts a pole-piece 8 on the pinion 6, which is unclutched from the pinion 7 and locked, so that the engine is turned through the gearing 2, 3, 4, 7 at reduced speed. When the dynamo is being driven from the engine, its speed can be maintained constant by means of the electro-magnet 9, which has a number of coils, one or more of which are used to vary the braking action on the disk 8 of the pinion 6.

Abstract: 788,693. Explosives containing T.N.T. AKTIEBOLAGET BOFORS. Feb. 20, 1956 [March 16, 1955], No. 5163/56. Class 9(2) Granulated explosive compositions containing T.N.T. are manufactured by including the portion of T.N.T. that, together with the other components of the explosive has been found empirically to give homogeneous uniform sized, non-sticking granules, in a suspension of the other components in water, while stirring well at a temperature exceeding the melting point of T.N.T., cooling the suspension to below the melting point of T.N.T. to obtain primary granules, and adding the remaining amount of molten T.N.T. to be included in the explosive, to the primary granules in the same or another suspension medium, e.g. ethanol or glycerol, while stirring well at a temperature below the melting point of T.N.T., so that the added T.N.T. forms a coating on the granules. The examples relate to the continuous or batch production of RDX, T.N.T., wax compositions containing 40 per cent T.N.T.

Title: Improvements in or relating to tailstocks for lathes and like machine tools
IPC: B23Q1/28
Filed: 1951-03-05
Abstract: 682,572. Lathe details. HARBECK, M., HARBECK, M., STEFFEN, H. and STEFFEN, E. March 5, 1951 [March 4, 1950], No. 5207/51. Class 83 (iii). A clamping arrangement for the tailstock of a lathe &c. comprises two clamping jaws arranged underneath the centre sleeve and oppositely movable along a horizontal axis by means of an operating lever secured to a vertical spindle which lies behind the tailstock and the axis of which intersects that of the jaws. The centre sleeve 1 is engaged by a pair of clamping members 3, 4, the former of which is pinned to a transverse spindle 6, while the latter moves freely thereon. A bush 5 is pinned to the rear end of the spindle 6 leaving a space between the bush and clamping member 4 which communicates with a vertical bore 14. A clamping lever 11 serves when rotated to move a plunger 9 in the bore and this movement may transmit clamping pressure to the members 3, 4, by filling the space below the plunger with a heavy viscous material. In a modification a dished spring may be interposed between the bush 5 and the adjacent clamping member and the plunger bears on the upper convex face of the spring to effect clamping.

Title: Production of slub yarns
Inventor: EDWARDS JAMES LEROY
IPC: D02G1/16
Filed: 1963-02-08
Abstract: 982,351. Spinning and finishing yarns. E. I. DU PONT DE NEMOURS & CO. Feb. 8, 1963, No. 5320/63. Headings D1F and D1W. A twisted or untwisted, natural or synthetic, continuous or staple fibre yarn, or a sliver or roving of staple fibres, is textured e.g. bulked, looped, crimped or "interrupted" (broken ends), and converted to slub yarn by forwarding one or more ends of yarn &c. by means of a high velocity e.g. 400-1000 yards per minute, stream of gas or vapour e.g. air or steam which may be heated and/or contain plasticizing agent (which separates the individual filaments) first through a jet and then against a foraminous surface from which the yarn is withdrawn through a second jet at a reduced velocity and subjected to the action of a second high velocity stream of gas &c. moving through the second jet and against the surface in a counter-current direction to the yarn. The process conditions may be uniform or, preferably randomly, varied, but in each case stable slubs of random size and distribution result and may be consolidated by a torque-jet as the second or a third jet which twists protruding loops or ends about the yarn and/or plies the slubbed yarn with a twisted or untwisted unslubbed yarn of similar or different composition. Additional twist may be imparted to the slubbed yarn. The natural fibres may be cotton, wool, linen, silk or mixtures thereof; the synthetic fibres may be of polyamides, polyesters, regenerated cellulose, cellulose esters, acrylic, vinyl and vinylidene polymers or copolymers thereof. Both streams have at least onehalf sonic velocity. As shown, zero-twist multifilament yarn 1 is withdrawn from package 2, through guides 3 and 5 and tension gate 4 by feed rolls 6, 7, about which the yarn makes several turns, then passes through a compressed air jet 8 and impinges, at an oblique angle of 30-60 degrees, on a foraminous screen 10 through which the air stream passes. The yarn is withdrawn through a slubbing jet 11 from which a second air stream is directed to impinge on the screen 10 adjacent the first stream so that turbulence created between the streams causes the yarn to twist, loop and entangle on itself. The jet 11 consolidates the slubbed yarn by intermingling of the folds, loops and filaments of the slubs and the base yarn bundle, and the final yarn passes from take-up roll 14 to the package 16. Suitable jets are described in Specification 871,112 and U.S.A. Specifications 2,985,995 and 2,997,837. Specifications 732,929, 892, 587, Belgian Specification 573, 230 and U.S.A Specifications 2,783,609, 2,874,444 and 2,931,090 also are referred to.

Title: Improvements in and relating to safety devices for gas conduits
IPC: A62C4/02
Filed: 1936-02-28
Abstract: <PICT:0453747/III/1> In the manufacture of sulphur, the admixture of sulphur dioxide and carbon monoxide in dangerous proportions due to the back flow of reducing gases such as CO, COS, CS2 and sulphur dioxide over the glowing coke layer in a gas producer when a blower fails, is prevented by a safety cut-off valve 5 which shuts off a conduit 3 supplied by the blower 1 from a conduit 2 where a subatmospheric pressure normally prevails.  The conduit 2 is simultaneously vented to atmosphere or to a safe part of the system. The fall in pressure in the conduit 3 acts through a pipe 7 on a fluid pressure relay 8 which opens the circuit of a solenoid 9.  The valve 5 is released by the descent of the solenoid core and the switch of a siren or other warning device is simultaneously operated.
