Title: Improvements in the production of textile fabrics having a crinkled or puckered appearance
IPC: D06C23/04
Filed: 1945-07-02
Abstract: A process for the production of fabrics having a crinkled or puckered appearance comprises simultaneous treatment of a fabric composed of yarns of a thermoplastic material and yarns of a non-thermoplastic material with heat, moisture and tension in the direction of the associated yarns, drying the fabric whilst still under tension and releasing the tension when the fabric is dry. The tension can be applied to either warp or weft or both, provided that it is applied to the associated yarns.  The degree of tension may extend the fabric 1-10 per cent (in the case of taffeta weaves 2-5 per cent).  Suitable thermoplastic yarns are cellulose acetate and other organic derivatives of cellulose, e.g. cellulose propionate, cellulose butyrate and ethyl cellulose or synthetic linear polyamide condensation products.  The nonthermoplastic yarns may be regenerated cellulose, saponified cellulose esters, cotton, linen or wool.  If the non-thermoplastic component consists of staple fibre yarns the latter should be of sufficiently tight construction to produce the desired regain on releasing the tension.  The process can be carried out most suitably following a dyeing operation (e.g. jig dyeing) and drying on a tenter.  The fabric is held on the tenter till substantially "bone-dry," i.e., its water content is equal to or less than that held in the fabric in equilibrium with the atmosphere.  In an example a tightly woven taffeta of cellulose acetate warp and a weft of cellulose acetate (6 picks) and regenerated cellulose (2 picks) alternating is jig dyed and while still wet is run through a tenter adjusted to extend its width from 39 to 40 inches.  The fabric may be wetted out in any aqueous bath prior to tentering or it may be treated with steam whilst in the tenter.  The temperature of the tenter should be high enough to ensure that the thermoplastic material loses some of its regain on removing the tension, e.g. for cellulose acetate, 90-150 DEG  C.

Filed: 1960-05-13
Abstract: 953,061. Control of D.C. motors. SINGER CO. May 13, 1960 [May 20, 1959], No. 16949/60. Heading H2J. [Also in Division G3] The speed of a series motor, e.g. for a sewing machine, fed through a rectifier from an A.C. supply, is controlled by comparing its back E.M.F. with a D.C. reference voltage and using the result to control the continuity of the motor current. The reference voltage, derived from an adjustable potential divider 12, 15, is rectified by a crystal diode 21 and applied to the gate electrode of a silicon controlled rectifier 18 connected between the motor field 10 and its armature 11. The back E.M.F., applied to the cathode 17, compared with the reference voltage at 20 determines whether the rectifier will conduct. The motor current is thus alternately switched on and off by the rectifier 18 as the speed of the motor, and hence its back E.M.F., fluctuates about the desired valve as determined by the setting of potentiometer 15.

Abstract: 274,835. Whitney Machine Co., (Assignees of Wheeler, J. A., and Whitney, R. F.). July 26, 1926, [Convention date]. Rotating tool machines.-A machine for performing on hide and leather such operations as unhairing, fine hairing, scudding, &c., comprises a rotary bladed drum of a flexible hide-support of approximately the same radius. A safety device is provided for the protection of the operator. The work-roll or drum 2 carrying scraping and spreading or other working blades 2a is rotated from a pulley 50 through chain sprockets 52, 54, 56, 4. The flexible hide support 5 is clamped at its upper end to a clamping bar 9 carried by rocking arms 12 and at its lower end to a bar 19 carried by rocking levers 21. The bar 9 cooperates, in clamping the hide (not shown), with a clamping bar 30 carried by rocking levers 31. The bar 9 is raised, to clamp the hide and carry it to position near the drum, 2, by links 14 and a crank 15 on a gear 16<a>, and the clamping bar 30 is lowered by rolls 32 and a cam 33 on the gear 16<a>. The arms 12 also operate the rocking levers 21 through links 29, 26 and spring pressed blocks 24. Spring stops 35, 35<a> limit rearward movement of the levers 31. The safety device comprises a bar 36 carried by curved arms 38 which are guided by rolls 40 to move the bar 36 forwardly as the clamping bars 9, 30 are closing. The rolls 40 are mounted on a sprinkler pipe 41. The gear 16<a> is rotated from the pulley shaft 64 through gears 60, 62, 63. An expanding frictional, one-revolution clutch operated by a treadle 70, and a brake drum and band, are associated with the pulley 50 and gear 62. In use, the clamping bars 9, 30 are normally widely separated and the hide support 5 is far removed from the drum. A hide or skin having been placed on the support and over the bar 9, the treadle 70 is depressed, letting in the clutch and loosening the brake band. The clamping bars 9, 30 then come together to clamp the hide, and the bars 9, 19 carry the support 5 and hide into proximity to the drum. The latter makes one revolution, the clutch is thrown out, and the parts return to inoperative position.

Abstract: 170,297. Huth Ges., Dr. E. F., Rosenbaum, B., and Loewe, S. Sept. 15, 1915. [Convention date]. Void [Published under Sect. 91 of the Act]. Modulating systems; transmitting systems; wired wireless systems.-A system of telegraphy or telephony either without wires or along wires is characterized by the employment of a fundamental or carrying frequency of such a value that the monotonous note on which the signal is superposed is either inaudible or barely perceptible. This fundamental frequency may however be lowered to distinct audibility, and such audible discharges may be emitted simultaneously with " silent " frequencies. The energy radiated may approximate to continuous waves; or the wave length may be so short as to prevent successive groups from merging together. The radiations are apparently generated in the same manner as in known shock-excitation or quenched-spark systems.

Title: Improvements in electric switching mechanism suitable for transformer tap-changing
IPC: H01H9/00
Filed: 1943-10-18
Abstract: 583,365. Heavy-current switches; arc-rupturing in switches. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 18, 1943, No. 17064. Convention date, Oct. 22, 1942. [Class 38 (v)] A transformer tap - changing switch suitable for the circuit described in Specification 500,763, [Group XXXV], and comprising a pair of non-arcing tapselector switches and an arcing- duty switch, is operated by a cam co-operating with a pair of diametricallyopposed followers such that, in a single revolution of the cam, each selector, together with the arcing switch, is opened and then closed. Separate contacts 3, 4 of a ratio-adjuster 5 are connected through halves of a split reactor 7 to common contacts 1, 2 mounted on insulators 8, 9 on the transformer-tank. Selector contacts 10, 11, pivoted to the contacts 1, 2, and engaging fixed contacts 12, 13, connected to conductor 14, are operated by linkwork 20, 21 terminating in followers 18, 19 which engage a cam 16 having a groove with a part offset in the axial direction and rotatable by a shaft 17 interlocked with contacts 3, 4. The arcing contacts 22, 23 are interconnected by a lead 26 and carried on members 28, 29 which are joined by a bar 27 and loosely mounted on the respective cam-follower shafts. By means of normally-separated projections 32 on the members 28, 29 and linkwork 20, 21, the arcing-contacts can be opened by either selector against the action of springs 30, 31, which reclose the arcing-contacts prior to reclosure of the selector. Thus, in one complete revolution of shaft 17, cam 16 opens, say, selector 10 and contacts 22, 23, contact 4 is arclessly moved to the tap where 3 is, and the cam then recloses 22, 23 and 10. Selector 11 and contacts 22, 23 are then operated and contact 3 moved one tap to the left, whereupon 22, 23 and 11 reclose. The reactor 7 averages the voltage of taps 3, 4 and acts as a circulating-current limiter, but load-current effects therein cancel out. The contacts 1, 22 may be shunted by a resistor 33 with the effects described in Specification 17236/43 (as open to inspection under Sect. 91).

Title: Manufacture of a synthetic oestrogenic agent
Filed: 1941-02-04
Abstract: 549,200. Synthetic oestrogens. DAVIES, J. S. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 4, 1941, No. 17240/40. [Class 2 (iii)] Tri-p-anisyl-bromoethylene is prepared by reacting bromine with tri-p-anisyl ethylene in approximately equimolecular proportions in an inert organic solvent, the reaction and removal of solvent being carried out at ordinary or elevated temperatures, provided that if temperatures above 100‹C. are used, the hydrogen bromide which is formed is rapidly removed from contact with the reaction product. The preferred method is to carry out the reaction at room temperature and allow the reaction to proceed without external heating, the solvent being removed under diminished pressure. Alternatively a solvent such as pyridine may be used which absorbs the hydrogen bromide as it is formed, or the reaction mav be carried out in nitrobenzene in the presence of sodium carbonate. In examples, bromide is added to tri-p-anisylethylene at room temperature in chloroform solution, the solvent removed under low pressure. There is then obtained tri-p-anisylbromoethylene. Other examples are included in which ether, glacial acetic acid, pyridine, chlorbenzene and nitrobenzene are used as solvents.

Title: Improvements relating to plants comprising a plurality of fluid compressors or generators of hot products of combustion under pressure, and particularly free piston compressors or generators feeding at least one receiving element
Filed: 1940-12-05
Abstract: 561,536. Air compressors. PESCARA, R. P. Dec. 5, 1940, No. 17326. [Class 7 (i)] [Also in Groups XXVI and XXVIII] In a plant comprising two or more air compressors or gas generators (in which a compressor supplies air to charge the internal combustion motor element driving it and the motor exhaust gases together with excess compressed air supply a turbine &c.), pressure fluctuations in the common receiver or supply are minimized by maintaining a set phase relationship between the machines, the speeds of which are automatically varied to correct any departures of phase relationship from that of a periodically operating pilot element which may be one of the compressors &c., or a metronome synchronous motor. Fig. 1 shows apparatus in which the piston of master and slave free-piston gas generators A<1>, A<2> are connected to valves 14<1>, 14<2> periodically interrupting fluid supply through a pipe 11 to a cylinder having a piston actuating a valve which controls communication between the pressure accumulator 7<2> of the slave compressor and sources of high and low pressure. In another form, Fig. 3, the fluid circuits which control the accumulator valve pistons 9<2> are interrupted by valves t<2>, t<1>2 actuated respectively by the compressor pistons and by cams on a shaft 18 driven by an hydraulic motor 19, the supply to which is controlled by a valve 20 controlled by a servopiston 9<1> subject to pressure of fluid passing through' valves t1, t<1>1 actuated by the pilot compressor piston and a cam or shaft 18 ; the piston 9<1> also controls the fluid outlet area of a valve 23, through a lever 24. A further modification provides means for employing any selected compressor of a set as pilot. Moreover, the set. phase relationships may be altered by making the shaft 18 in sections, the angles between which can be varied by hand or automatically.
