Title: Improvements in the manufacture and production of artificial threads, filaments and the like
IPC: D01F4/00
Filed: 1941-05-27
Abstract: 549,642. Artificial silk etc.; proofing artificial threads. COURTAULDS, Ltd., WORMELL, R. L., and KNIGHT, C. L. May 27, 1941, No. 6778. [Class 2 (ii)] [Also in Group VIII] The resistance to attack by boiling water or hot dilute acid of artificial threads having a basis of casein, vegetable seed protein or other protein is improved by .treating the threads with a solution containing formaldehyde and an alkali metal bisulphate or an alkali metal sulphate and sufficient sulphuric acid to convert at least a large proportion of the sulphate into bisulphate. This treatment may be effected during or after one or more hardening treatments e.g. with aqueous solutions of formaldehyde or metallic salts such as aluminium. Bleaching agents such as sodium hydrosulphite may be added to the bisulphate-formaldehyde bath. During the treatment the threads may be placed in a heavy cage or wire frame or other sinking device in order to keep them immersed in the liquid which is of high specific gravity. In an example, freshly spun casein threads are hardened in a solution of aluminium sulphate, formaldehyde, and sodium carbonate. They are washed and then immersed in a solution prepared by dissolving sodium sulphate, sulphuric acid, formaldehyde, and aluminium sulphate in water. The threads are soaked in very dilute sulphuric acid and then placed in a solution of chromium sulphate and formaldehyde. They are subsequently washed with sodium carbonate solution and with water and then given a soft finish by treating with a solution containing Turkey Red oil and sodium bicarbonate. In another example, artificial filaments from a solution of soya bean protein are hardened with a solution of aluminium sulphate, common salt, sodium sulphate, and formaldehyde. They are washed and treated with a solution of sulphuric acid, sodium sulphate, aluminium sulphate, and formaldehyde, first at room temperature for several hours and then at a higher temperature. In another example, hardened casein fibres are treated with a solution of sodium sulphate and sodium carbonate, and then with a solution of sodium bisulphate and formaldehyde.

Abstract: 962,232. Capacitors. RADIO CORPORATION OF AMERICA. Feb. 24, 1961 [March 24, 1960], No. 6925/61. Heading H1M. A method of fabricating a solid electrolytic capacitor comprises the steps of pressing a powder of anodizable metal, such as tantalum, colombium, beryllium, tungsten, aluminium &c. into a porous pellet, vacuum sintering said pellet, electrolytically treating said pellet in an aqueous solution of a compound capable of pyrolytic conversion to a semi-conductive metal oxide so as to simultaneously anodize said pellet and impregnate the pores with the compound, heating to convert said compound into said semi-conductive metal oxide, repeating at least once the steps of anodizing and pyrolytically converting the compound, and finally depositing a conductive coating upon said pellet. Two embodiments are described by way of examples. The first employs powdered tantalum for the pellet, sintered at 1750‹ C., fitted with an anode lead and treated in successive baths of manganous nitrate solution. The first forming voltage is of the order of 60 volts followed by a second at 45 volts. A coating of graphite is then given, followed by a sprayed coating of silver-loaded epoxy resin to which a cathode lead of nickel ribbon is cemented with the same resin. In the second embodiment for the production of capacitors with a thicker dielectric, i.e. lower capacity ratings, powdered columbium is employed which after sintering at 1500‹ C. is placed in forming baths of nickel nitrate solution, and subject to a first anodization at 180 volts, followed by a second at 50 volts which is repeated four times. A coating of graphite is then given, a portion adjacent the anode lead is masked and the remainder sprayed with tinlead solder to a gold-plated nickel ribbon lead is soldered.

Abstract: 1,037,853. Hydraulic apparatus. H. TEVES, E. A. TEVES and M. TAUSEND [trading as ALFRED TEVES MASCHINEN-UND ARMATURENFABRIK KOMM-GES]. Feb. 20, 1964 [March 1, 1963], No. 7111/64. Heading F1P. [Also in Division F2] The piston of a ram 36, Fig. 3, is maintained in the position shown by fluid pressure from a pump 34 acting in ram chamber 38 via a line 3 and a pilot-actuated valve 40 in its position 40b. To extend the ram piston two electrically operated valves 41, 42 are placed into positions 41a and 42b, so that the pilot controls of valves 39, 40 are connected to a tank 35 and the pump 34, respectively; the valves 39, 40 then move into positions 39b and 40a. Ram chamber 38 is now open to the tank 35 so that another valve 33 opens and moves into a position 33b whereupon pressure fluid from the pump 34 flows through valves 33, 39 into ram chamber 37 to extend the ram piston. Upon the latter completing its stroke the pressure build-up in chamber 37 acts via valve 39 on valve 33 and causes this valve to close so generating an electric signal in a winding 25, which signal is transmitted by leads 26, 27, a transistor 44 and a counting stage 45 to an output stage 46 connected to the two opposed operating-coils of the valves 41, 42. A pressure relief valve 43 is provided. The valve 33 has an inlet 2, Fig. 2, connected to the pump and an outlet 3 leading to the ram and as long as the pressures in the inlet and outlet are equal a spring 24 urges a closure member 23 on to a seat 20. When the pressure falls in the line 3 due to commencement of a ram stroke the member 23 is unseated by the pump pressure and travels into the spring chamber 31 at a speed that is dependent upon the position of a throttle 30 through which the chamber 30 is connected to the outlet 3. The member 23 is also the core of the winding 25 so that movement of the member 23 produces a current pulse in the line 26, 27. When the pressure at the outlet 3 again reaches the level of the pump pressure the spring 24 reseats the member 23 and another current pulse is generated in the lines 26, 27.

Inventor: MYERS ALBERT WALTER
IPC: B64D17/00
Filed: 1917-05-18
Abstract: 111,802. Myers, A. W., and Fitzgerald, R. R. May 18, 1917. Parachutes.-A parachute for attachment to aerial machines is normally held closed by a keeper 12 and retained in the horizontal position by a trip lever 27, but, when released from this trip lever, is forced by springs 18 into the vertical position and then forced upwards by a spring 9 and opened by a spring 22. The rod 14 of the parachute 11 is surrounded by a sleeve formed in two parts 16, 16<b> pivoted together at 17 and acted on by the springs 18. The parachute is normally held with its lower end compressing the spring 9 within a fixed casing 5, by the engagement of a spring catch 19 with a notch 7 in a fixed rod 6. When the trip lever 27 is disengaged from the parachute by means of a rope 29, the parachute is moved into the vertical position, at first by a spring 26, but mainly by the springs 18 acting on the sleeve part 16. As this part closes against the part 16<b>, a cam-ring 20, connected by a link 21 to the part 16, is pulled upwards and releases the catch 19, whereupon the parachute is forced upwards by the spring 9. Ropes 10, 24 thus become drawn taut and move the keeper 12 downwards, allowing the parachute to open.

Title: Cereal flakes and process of making same
IPC: A23L1/168
Filed: 1923-03-13
Abstract: 217,634. Marks, E. C. R., (Postum Cereal Co., Inc.). March 13, 1923. Cereal preparations.-A flaked cereal food is produced by treating the grains to toughen the bran and the outer layer of endosperm, milling so as to separate the bran and adhering endosperm in flakes, cooking at a temperature of 112‹ to 115‹ C. so as not to destroy the vitamines, drying. flaking under a pressure that will rupture the cells of the bran envelope, and re-heating at approximately the same temperature as before. The grain is washed and stored for an hour or so in a moist state and milled between corrugated rolls one of which one rotates from 2¢ to 3¢ times as fast as the other. The flakes thus produced are sifted free from the inner parts of the endosperm, leaving a product containing 65 to 70 per cent of bran and 30 to 35 per cent of adhering endosperm. This product, with or without the addition of salt and malt syrup, is cooked in a rotary steam cooker, dried, again sifted, and passed through smooth rolls pressed together by springs which for rolls 20 inches in diameter and 24 inches long, exert a pressure of about 30 tons. The flakes are then passed through an oven, which may have a temperature of 176‹-194‹ C., but the temperature of the flakes must not be allowed to rise above 115‹ C.

Abstract: 1,161,948. Supply systems for discharge lamps. SENTA - DORIS GRIEDER - ZIMMERLI. 15 Feb., 1967 [15 Feb., 1966], No. 7291/67. Heading H2H. A xenon long arc lamp 7 is started and supplied by the circuit shown in the Figure in which a transformer 1 is connected to an A.C. supply 3 and has an output voltage at least equal to the rated operating voltage of the lamp but substantially lower than the lamp ignition voltage, and an additional transformer 15 has a primary winding 19 connected to an A.C. supply 11 and a secondary winding 17 which boosts the circuit voltage to the ignition value. To start the lamp, a manually-operated switch 13 is closed to energize a conventional high frequency starting device 5 from the supply 11, the winding 19 being energized through a switch 21 whose control coil 23 is supplied from a current transformer 25 in the lamp circuit. When the current therein reaches a predetermined value corresponding to lamp operation, the switch 21 is opened to de-energize the winding 19 and allow the winding 17 to act as a ballast for the lamp, the core of transformer 15 being saturated by the lamp current. Operation of the relay arrangement 21, 23 may be achieved in alternative ways, e.g. using magnetic, capacitive or photo-electric means, this last method being responsive to the light emitted by the lamp. The transformer 25 may be combined with the transformer 15 which would then have a third winding supplying the coil 23, or may be omitted in which case the coil 23 is connected directly in the lamp circuit. The light output of the lamp may be varied by providing the transformer 15 with a D.C. energized winding to vary the saturation of the core, this winding being energized after ignition of the lamp by further contacts controlled by the coil 23, Fig. 4 (not shown). Each of the windings of transformer 15 may comprise two halves wound on separate cores and connected series-aiding in the case of windings 17, 19, and series-opposing in the case of the D.C. energized winding, Fig. 4 (not shown). In another modification, Fig. 5 (not shown), the transformer 25 supplies another coil (53) whose contacts (55) bridge part or all of the winding 17, the relay arrangement (53, 55) having a time delay so that part or all of the winding 17 is short circuited at a predetermined time after de-energization of the winding 19. Circuits are described, Figs. 2 and 3 (not shown), in which two or three lamps, each supplied as shown in the Figure, are operated from a three phase A.C. supply using separate or combined transformers 1.
