Title: Improvements in yarn patterned fabrics
IPC: D06Q1/02
Filed: 1947-08-08
Abstract: Etched or burned out patterns are produced on fabrics consisting of nylon yarns and either rayon yarns or yarns of vegetable or animal origin by removing one kind of yarn by solvents or degrading agents, the other yarn being unattacked. The yarn woven with the nylon may be cotton, wool, silk, regenerated cellulose or a cellulose derivative. For the selective removal of portions of natural or regenerated cellulose yarns reagents such as calcium thiocyanate, cuprammonium hydroxide, certain quaternary ammonium compounds such as dibenzyl dimethyl ammonium hydroxide, zinc chloride, zinc-hydrochloric acid mixtures, sulphuric acid, hydrochloric acid, phosphoric acid, aluminium chloride, aluminium sulphate, magnesium chloride and other hydrochloric acid-liberating salts may be employed. Cellulose derivative yarns are removed by suitable solvents such as acetone for cellulose acetate.  Silk or wool may be removed with strong alkalis (NaOH, KOH).  Prolonged contact of the nylon with strong mineral acids and caustic alkalis should be avoided. Nylon may be removed by the action of phenol or concentrated formic or acetic acid.  The fibre-removing agent may be printed directly on to the fabric, or the fabric may be printed with a suitable resist and then impregnated with the reagent.  In examples: (a) a fabric of nylon yarns and cellulose yarns is printed with a paste of aluminium sulphate and dextrine, heated to 248 DEG  F. for 10-20 minutes and the carbonized portions removed by rubbing, brushing and/or soaping; (b) a fabric of nylon and cellulosic yarns is printed with a paste comprising thickened sulphuric acid, heated to 210 DEG  F. for 15-20 minutes and treated as in (a); (c) a fabric of nylon yarns and cellulosic yarns is printed with a phenol-dextrine paste, heated to 100 DEG  F. for 10-20 minutes to swell and dissolve the nylon in the printed areas, the solubilized yarn portions removed by suction and the fabric washed.

Title: Improvements relating to the internal coating or treatment of pipes
Inventor: FORSTER HENRY ATKINSON RONALD
IPC: B05C7/04
Filed: 1965-05-24
Abstract: 1,111,371. Coating apparatus. AULT & WIBORG PAINTS Ltd. 24 Aug., 1966 [24 May, 1965], No. 21973/65. Heading B2L. In coating the inside of a pipe the pipe and a spreading device situated for co-axial entry into the pipe are caused to move rotationally and longitudinally relative to one another to spread an appropriate quantity of coating medium previously deposited, along the pipe. A pipe 1 is supported on a series of plates 4 mounted on side rails 2 carried by trestles 3. A shaft 11 is mounted for longitudinal and rotational movement on a similar support structure consisting of carriers 8, 9, 10; side rails 6 and trestles 7, so as to be co-axial with the pipe 1. Rotational movement of the shaft 11 is effected by motor 19 through gearbox 20 and longitudinal movement is effected through motor 25 through a chain drive mechanism. Alternatively a single motor may be used by both movements. The carriers 8, 9, 10 can be rotated in unison to positions I, II or III to provide appropriate support positions to the shaft 11 during its longitudinal movements. In use a cannister 31 into which coating material has been poured through aside slot 31a (Fig. 17, not shown) is attached by a bayonet connection to the shaft 11 and the shaft is advanced until the cannister 31 is just inside the pipe 1. The shaft 11 is then rotated through 180‹ so as to bring the slot 31a to its lowest position. The shaft 11 is then moved longitudinally through the pipe 1. The cannister is slightly less in diameter than the pipe so that coating material is deposited from the cannister 31 on to the inside of pipe 1. As the cannister emerges from the other end of pipe 1 the shaft is again rotated 180‹ to bring the slot 31a to its uppermost position and the cannister is then removed from the shaft 11. A spreading device, Fig. 16, is then attached to the shaft 11, motor 19 is switched on to rotate the shaft 11 and motor 25 is switched on and gear box 27 or 29 operated to cause reverse longitudinal movement of the shaft 11. The spreading device is thus drawn back through the pipe and by the combined successive action of the spreading combs 36 and the brush heads 41 the coating material is spread uniformly on the inside of the pipe. The toothed edges of the combs 36 are biased radially outwards by two series of coil springs 39 and a tapered radial guide having vanes 35 is provided for facilitating entry of the spreading device into the pipe.

Title: Improvements in temperature controlling apparatus and in relays
IPC: H05B1/02
Filed: 1925-09-04
Abstract: 255,405. Etablissements Poulenc FrÞres, and Chagnaud, A. July 17, 1925, [Convention date]. Indicating.-An apparatus for controlling an electric or other furnace comprises a temperature indicator, the needle of which masks or unmasks a photo-electric cell which controls the heating device of the furnace. A luminous source 1 is placed in front of a condenser lens 2 which causes convergence of the light on a window 3 formed in the dial of a galvanometer actuated by a pyrometer in a furnace 6. The light may be obstructed by a plate carried by the galvanometer needle when the temperature reaches a certain point. The light is received on a selenium cell 9 connected with a relay 11 so that the movable plate 12 makes a contact 13 when the temperature of the furnace is too low. The relay controls a series of contacts 16 - - 20 by the aid of mercury interrupters moved by iron cores 21, 22, in solenoids 23, 24. Contacts 16, 17, energize the solenoids, contacts 18, 19 operate visible or audible signals, and contact 20 acts on the heating resistance or other controlling means of the furnace. If contacts 16, 18, 20 are closed and contact 13 is made, a resistance 26 in the heating circuit is short-circuited and the resistance 29 causes a rise in temperature. If contacts 17, 19 are closed and contact 13 is made, solenoid 23 is energized and contacts 16, 18, 20 are thereby closed, and contacts 17, 19 opened, the resistance 26 being again short-circuited. If the furnace becomes too hot, contact 14 is closed, solenoid 24 is energized, and contacts 17, 19 closed and 16. 18, 20 opened, so that the resistance 26 is placed in circuit and the temperature falls. The window in the galvanometer may be adjustable, or if fixed, a variable resistance 31 is inserted in the pyrometer circuit to enable the temperature control point to be adjusted. Fig. 3 illustrates the relay 11. An electromagnet 33, 34 is adjustable by a knob 35 with respect to an armature 12, pivoted at 38. Contacts 13, 14 are adjusted by knobs 39, 40. The plate 12 is balanced by a spring 43 attached to a member 44, which is movable in a slide 45 to give a coarse adjustment. Fine adjustment is effected by a micrometer screw 47. The apparatus may also be used for controlling a valve or by-pass for gas, steam, or the like.

Filed: 1946-07-26
Abstract: 614,760. Blasting-cartridges. TAYLOR, J., THOMSON, T., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 26, 1946, No. 22298. [Class 9 (1)] Relates to blasting devices in which a pressure-resisting container is separated from a perforated discharge head by a closure adapted to yield at a predetermined internal gas-pressure produced without detonation from a charge within the container, the gases evolved causing a blasting effect without flame, as described in Specifications 431,935 and 461,647. According to the invention, an assembly of such devices are electrically connected for simultaneous firing and successive blasting operation, some at least of the charges being associated in initiating relationship with non-detonating delay electric initiators having a predetermined delay time-interval. A tubular steel container 1 is separated from a discharge head 2 by a closure 3 yielding at an internal pressure of several tons per sq. in. Through a firing head 4 an insulated conductor 5 leads from a terminal socket 6 to a plug electrode 7 attached to a non-detonating delay initiator 9, situated in the gas-evolving charge 10, and comprising a paper cylinder 11, filled with a charge 17, Fig. 3. A leading wire 14 connects the electrode 7 to a delay electric powder fuze 13. The return wire from the fuze 13 is expanded to a terminal strip 15 soldered to a copper ring 16 between the plug 12 and container 1, thus completing the circuit to the terminal 8. The charge 17 is 200 grains of black powder and is the main initiating charge. The gas-evolving charge 10 is a powder mixture of sodium nitrite and ammonium chloride with anhydrous sodium carbonate in the proportions 55.25 : 43.25 : 1.50 by weight. The delay electric powder fuze 13 consists of a thin metal tube 19, Fig. 4, within which is a low-tension electric fuze-head 20. Below the fuze-head 20 is a metal delay sleeve 24 filled with a delay composition 25 to give the requisite delay to initiation of an igniting composition 26 after closing of the electrical circuit. Delays from ¢ to 5 secs. may be provided by varying their length and composition. The composition 26 ignites a charge of loose black powder 27 to initiate the charge 17 and hence charge 10. A number of containers 1 having different delays and placed in prepared bore holes are connected in series and fired simultaneously on closing a key in the circuit. Potassium or ammonium perchlorate may be used to shorten the period of decomposition of the charge 10.

Abstract: 866,125. Radio navigation. MINISTER OF AVIATION. Oct. 13, 1959 [July 16, 1958], No. 22803/58. Class 40(7) A lightweight transistorized supplementary warning device connected across the input to the glide path indicator of the instrument landing system (I.L.S.) of an aircraft provides an aural and/or visual warning signal when the aircraft is flying below the normal glide path. As shown the D.C. voltage across the input to the normal glide path pointer indicator is amplified by a pair of transistors 4, 5 and applied as a switching signal across one diagonal of a germanium diode bridge, the output from an audio frequency transistor multivibrator 16 being applied across the other diagonal such that when the amplitude of the switching voltage exceeds a value corresponding to the maximum safe displacement of the aircraft below the glide path, the bridge 11 becomes conductive and applies the output from the multivibrator 16 to a transistor audio amplifier 24 whose output is coupled by a transformer 27 to the aircraft inter-communication system to provide an aural warning. A visual warning is provided by applying an output from the amplifier 24 through a further transistor amplifier 28, 29 to energize a relay 30 thereby closing contacts 31 to light a lamp 34 which is connected in parallel with one coil 33 of two relays B and C which are so interconnected to cause the lamp 34 to flash on and off.

Filed: 1950-09-18
Abstract: 672,590. Projectile fuzes. ANSTALT FUR DIE ENTWICKLUNG VON ERFINDUNGEN UND GEWERBLICHEN ANWENDUNGEN ENERGA. Sept. 18, 1950. [Sept. 26, 1949] No. 22897/50. Class 9 (i). A safety device controlling the arming of a projectile fuze has a body 1 housing an obturator 2 which is retained by a keeper ring 3. The body 1 is crimped into a casing 5 which has a lower part 5a in which is inserted a sleeve 6 housing a detonator 7 covered by a perforated cap 8 over a wad 10, a plug 11 retaining the sleeve in the casing. Through the obturator 2 extends a passage 12 having an eccentric part 13. Extending through the base of the body 1 is an oblique passage 14, the passages 13, 14 being diametrically opposed relative to the axis of the projectile before arming. An annular inertia member 15 between the body 1 and the casing 5 is held by a spring 17 and is provided with a guide member 18 extending through an aperture 19 in the body 1. When the projectile is fired, the inertia member 15 recoils against the spring 17 and is guided in its translatory motion by the member 18 the end 20 of which moves along a groove 21 in the obturator 2, thereby rotating the obturator. When the obturator has turned through 180 degrees the passages 13, 14 are aligned so that flash from a nose fuze can pass to the detonator. The groove 21 has an undulating part 21a leading into a helicoidal part 21b beyond which is a blind part 21c, Fig. 2. Due to this form of the groove, the obturator is initially given a reciprocating movement before rotating through 180 degrees. When positive acceleration of the projectile ceases the end of the guide member 18 becomes locked in the blind part of the groove and the projectile is permanently armed. A waxed cardboard capsule 22 may be placed in the passage 13 to ensure gas tightness prior to arming.
