Title: Improvements in or relating to electric conductors connected to metallic thimbles
IPC: H01J5/40
Filed: 1938-09-15
Abstract: 519,117. Electron discharge devices &c. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 15, 1938, No. 26916. Convention date, Sept. 18, 1937. [Class 39 (i)] [Also in Group XXXVI] In apparatus. such as an electron discharge device, having a plurality of adjacent conductors connected to metallic thimbles, the thimbles are so shaped and arranged with respect to the magnetic field generated when alternating current flows in the conductors that substantially no line of magnetic force lies partly within and partly without the material of said thimbles, As shown, conductors 2, 3, are sealed to a vitreous envelope 1 by cylindrical metal thimbles 4, 5, eccentric to the conductors ; the latter may be continuous or in coaxial parts welded to the thimbles. Formulae are given for calculation of the eccentricity when the two conductors, and also the two thimbles, are of the same or different diameters. Where three or more conductors are used, resulting in non- circular lines of force, the thimbles are shaped accordingly.

Title: Improvements in and relating to pile fabrics and their treatment
IPC: D03D27/00
Filed: 1936-10-05
Abstract: 484,795. Pile fabrics. STEPHENS, A. J. (Collins & Aikman Corporation) Oct. 5, 1936, No. 27003. [Class 142 (iv)] Groups of pile warp threads say two, 3, 8, pass through each reed space whereby spaced groups, each comprising two rows of pile tuft 19, Fig. III, are formed. The fabric may be woven in a double plush loom, ground warp threads 2, 5, 7, 10 for the upper fabric and warp threads 1, 4, 6, 9 for the lower fabric, in addition to the pile warp threads 3, 8 passing through each reed space and interweaving as shown. At each side of each tuft, a ground warp thread passes over the weft which the tuft passes under and thus supports it whilst the legs of each pile loop are supported by sections of adjacent wefts having no pile thereon. The tufts are staggered and slightly inclined, but the pile face appears uniform. The backing of the fabric is impregnated through the back with an adhesive binder material which does not fill the interstices between the threads but is confined to the backing and adjacent parts of the tufts as shown in Fig. XI so that the ventilating properties of the fabric are not destroyed. The binder material may comprise latex, artificial dispersions of rubber or synthetic rubber. To remove or neutralize water repellent matter such as wax, grease, &c. the fabric before impregnation may be treated locally or generally with soap, ammonia, or oil solvents, such as ethylene dichloride trichlorethane, carbon tetrachloride or emulsified with water. Reference is also made to treatment with sodium oleate and trisodium phosphate solution. When it is undesirable to wet the fabric, for example if it contains predyed yarns it is treated with fuller's earth or other absorbent clay or chemically treated silicate. If diethylene glycol has been added to the fibres of the fabric during the spinning &c., it is removed by treatment with water. Apparatus for scouring the fabric &c. and then impregnating it is described. The fabric may have cotton wefts and backing warps, and pile warps of a mixture 50 per cent wool and 50 per cent mohair or a blend of 10 per cent cellulose acetate, 45 per cent wool and 45 per cent mohair. The fabric may be used for automobile upholstery. Specification 484,792 is referred to.

Title: Improvements in reciprocatory traverse mechanism for carding engine feed apparatus
Inventor: BIRD JACK
IPC: D01G15/36
Filed: 1953-10-05
Abstract: 748,097. Feeding-apparatus for carding engines. T.M.M. (RESEARCH), Ltd. Sept. 27, 1954 [Oct. 5, 1953], No. 27276/53. Class 120(1). In Scotch or like feed apparatus for carding engines a feed element is guided across a receiving surface by a member attached to an endless chain, belt or the like which is trained over sprockets, pulleys or the like so that it follows a path having substantially horizontal upper and lower courses with inclined end portions. This provides at the ends of each stroke, a slower traverse and hence a slight increase in the weight of material delivered per unit length of traverse. As shown, the lower ends of feed lattices 18, 19 of a Scotch feed apparatus are reciprocated along rollers 11, delivering on to a lattice conveyer 10, by means of a cross-head 27 on an endless chain 26 engaging a slot 28 in a carriage 16 slidable along rails 14, 15. The end portions of chain 26 are inclined to the horizontal as they pass between pairs of idler sprockets 33, 34 and the end sprockets 21 and 22, thus providing a reduced speed of horizontal traverse over these portions. Each end sprocket is mounted in a slidable block 24 and is connected to the corresponding idler sprockets by a pair of scissor links 35, 36; adjustment of the spacing of a pair of idler sprockets by means of a double-threaded lead screw 29 will thus vary the position of the end sprocket, enabling the length of traverse to be regulated. Sprocket 22 is connected to a sprocket 39 which is driven by a chain 38 from a sprocket 37.

Filed: 1946-09-13
Abstract: 654,933. Charging batteries. SHARP, J. R., and KAYE, E. Sept. 13, 1946, No. 27615. [Class 38 (iv)] [Also in Group XXXVII] In an electric motor and control installation for starting and driving a vehicle (see Group XXXVII), the driving motor 11 may be used to charge a battery 12-13 which supplies the motor during normal operation. An electromagnetically-operated switch 34, which is effective during motoring operation, is rendered ineffective when the motor is used regeneratively, or as a driven machine for charging the battery, by means of a polarizing winding 47. A charging current control relay has windings 50 and 51 and normally-closed vibratory contacts 52 and 53. It is adapted to place resistor 30 in series with shunt field winding 26 when the charging-current exceeds a given value. When a control rod 58 is moved to the left for charging operation, contacts 56, which short-circuit contacts 52 and 53 during motoring operation, are open, a clutch 38, which couples the motor 11 to the vehicle, is disengaged, and a squirrel cage motor 64 is placed in circuit. The motor 64 is started by the motor 11 when the main contacts 18 and 19 close, and thereafter drives the motor 11 to charge the battery. The A.C. mains motor may be used, as a slip clutch, its stator being capable of rotation. During charging operation the stator is held by braking the driving wheels of the vehicle to which it is coupled for motoring operation. Specification 654,951, [Group XXXVII], is referred to. Specification 597,919 is referred to in the Provisional Specification.
