Title: Improvements relating to stiffened textile fabrics
IPC: D06M17/02
Filed: 1938-03-25
Abstract: 512,820. Treating textiles with liquids. BRITISH CELANESE, Ltd. (Celanese Corporation of America). March 25, 1938, No. 9203. [Classes 2 (ii) and 15 (ii)] [Also in Group VIII] A'single layer of fabric containing yarns of a thermoplastic cellulose derivative is stiffened, two or more such fabrics are united, or one or more such fabrics are united with one or more non-thermoplastic fabrics, by subjecting to heat and pressure in the presence of an assisting liquid which contains a substantial proportion of a true solvent for the cellulose derivative and which, while not a solvent for the cellulose derivative at ordinary temperatures, becomes one at elevated temperatures. All the ingredients of the assisting liquid, except small quantities of non-volatile substances such as plasticizers and pigments, are sufficiently volatile to be entirely removed at the treating temperature. The cellulose derivative fabric may be woven, knitted, or netted from cellulose derivative' and, if desired, non-thermoplastic yarns, e.g. cotton, linen, regenerated cellulose, or silk. The non-thermoplastic fabric may be silk, cotton, or linen. The assembly to be treated may comprise fabric layers woven together and interconnected by extra warp or weft threads. As true solvents for cellulose acetate, acetone, dioxane, methylene ethylene ether, methyl acetate, diacetone alcohol, and methyl glycol are suitable, with latent solvents, e.g. lower alcohols such as methanol, ethanol, and isopropanol as diluents and, if desired, small quantities of non-solvents such as water. A plasticizer may be added to the liquid or may be applied to the cellulose derivative or non- thermoplastic fabric, for example, ethylhydroxyethyl-, methyl-methoxyethyl-, methylethoxyethyl-, di-(methoxyethyl)-, dimethyl-, or diethyl-phthalate, triacetin, diglycerine acetate, acetophenone, benzophenone, dibutyl- or diamyltartrate, or triphenyl phosphate. The assisting liquid may consist of industrial alcohol or methanol, acetone or dioxane, and isopropyl formate, methyl or ethyl acetate, diacetone alcohol, or methyl glycol. The fabrics may be shaped or moulded during pressing. Cuffs, collars, brassieres, belts, gauntlets, shoe uppers, and hats may be made. Besides cellulose acetate, cellulose propionate, butyrate, nitrate, acetate-propionate, acetate-butyrate, acetatenitrate, ethyl or benzyl cellulose, or ethyl cellulose acetate may be used. The Provisional Specification describes also the use, instead of cellulose derivatives, of polyvinyl acetate or chloracetate, polyvinyl ethers, polyacrylic and alkylacrylic esters.

Title: An improvement in or relating to rolling mills
Inventor: WILSON ALEXANDER IAN
IPC: B21B31/02
Filed: 1964-03-06
Abstract: 1,075,701. Rolling. HILLE ENGINEERING CO. Ltd. Feb. 26, 1965 [March 6, 1964], No. 9576/64. Heading B3M. A rolling mill comprises two rolls 10, 12 mounted in chocks 14, 16, 18, 20, the pairs of chocks at each end being automatically moved bodily by half the amount by which one of each of the pairs of chocks may be adjusted to vary the roll gap.

Abstract: 1,101,742. Regulating fuel injection I. C. engines. MIRRLEES NATIONAL Ltd. March 5, 1965 [March 7, 1964], No. 9754/64. Heading F1B. In a fuel injection system pressurized fuel is admitted to both ends of a metering pump piston 21, Fig. 1 which is loaded towards an adjustable stop 36, a valve 12 whilst maintaining the fuel pressure at one end momentarily opens the delivery end to the injection nozzle passage 43 whilst closing it from the fuel supply and after each injection reopens it to the fuel supply whilst closing it off from the injection nozzle passage. Operation: Before each injection all parts are as in Fig. 1; the fuel pressure, via restrictor 35 is admitted via passages 34, 33, restrictor 31, valve 12 passage 29 and port 26 to both ends of piston 21. The piston is urged by spring 25 into engagement with tappet 36 which is controlled by the governor rack (not described). Valve 12 is moved in synchronization with the engine and in its initial upward movement closes passage 32 and cuts off fuel pressure to the delivery end of the cylinder. Further upward movement of the valve spans passage 29 to the injector passage 43 whereby the fuel pressure above the piston 21 causes injection of the metered piston displacement volume. The opening of port 17 admits pressure to port 40, Fig. 2, thereby causing piston valve 38 to move against the loading of spring 42 to open port 41 to drain 41a. Downward movement of piston 21 connects port 28 with port 27 and cuts off port 26. Fuel pressure to the injector collapses in passages 29 and 43 when the fuel can pass via passages 30 and 40 to the port 41 and drain 41a. Valve 38 closes port 41 when the pressure has dropped sufficiently. The further descent of the metering piston is arrested by the fuel trapped by the closing of port 26. The injection nozzle valve and valve 38 operate to hold pressure in passage 43. Return movement of valve 12 reopens port 15 so that fuel pressure, via passage 29 and an inlet valve 23, reaches the underside of piston 21. Spring 25 moves piston 21 to open port 26 and close ports 27 and 28, the system returning to the position shown.

Abstract: 351,554. Type-printing telegraphy. CREED & CO., Ltd., CREED, F. G., and SALMON, R. D., Telegraph Works, Croydon, March 28, 1930, No. 9926. Addition to 228,842, [Class 40 (iii), Telegraphs, Electric]. [Class 40 (iii).] The parent Specification described a start-stop telegraphic receiver wherein five interponents are successively set by a single "adjuster," capable of both longitudinal and lateral movements, in accordance with received impulses, so as to determine the character to be printed. According to the present invention this receiver is modified to effect tape-perforation. The armature 11 of a relay, which may comprise a mechanical relay such as that described in Specification 302,259, [Class 38 (v), Electric switches &c.], is set to right or left by the received signals in accordance with the polarity, releasing the friction-driven clutchmember 16a for half a revolution at each change of polarity. The rock shaft 18 is thereupon tilted through a small angle by linkwork 20 to one or other of two positions in accordance with the position of armature 11, and on receipt of the start impulse it is set in that position in which it effects (through a link 23) release of the catch 14, whereupon the cam shaft 1 is clutched to a driving shaft. The stop impulse, being of opposite polarity to the start impulse, restores the latch 21 and so stops the cam shaft 1 at the end of a revolution. The five punches 49, of which only one is shown, are adjacent to five cross-shaped rockable interponents 24, which can be set by an adjusting pin 32 so that their limbs 48 hit or miss their respective punches when the carriage 46 is driven forward, towards the end of a signal period, by the bell crank 44 which is pivoted at 45 and is actuated by the cam groove 2. A single adjusting pin 32 serves for adjusting successively all five of the interponents 24: it is carried in front of them in succession by the bar 33, in which it slides, and which moves longitudinally under the control of cam groove 3. At the middle of each of the five signal impulses cam groove 4 causes blade 34 to move towards pin 32 and to hit it or miss it according to the position of rock bar 18 (i.e. according to the polarity of the signal impulse), since blade 34 is guided by two guides 39 rigid with the rock shaft. The interponents 24 are subsequently restored by lever 57, which is operated by cam 5. During the setting of the interponents 24 the tape is fed forward by pawl 66, which is controlled through linkwork by cam 3. For starting and stopping the motor (not shown) the switch described in Specification 284,740 may be emploved, so that the motor is switched off when signals have ceased to arrive during a definite interval of time.
