Title: Improvements in or relating to the manufacture of Leather-like Sheet Material
IPC: D04H1/58
Filed: 1967-08-01
Abstract: 1,196,308. Leather substitutes. USM CORP. Aug. 1, 1967 [Aug. 2, 1966], No. 35179/67. Heading C6C. [Also in Division D1-2]. A leather substitute is made by applying an aqueous suspension containing 1 to 5% wt. of swollen distinct collagen fibres of microscopic size to a fibrous sheet lightly rolling the sheet and thereafter applying a first liquid treating agent to the sheet to remove swelling water from the collagen fibres and re-aggregate them into a larger collagen fibre structure. The rolling assists penetration of the liquid treating agent into the web. The collagen fibre suspension can be made by tanning hide with aldehyde then beating in water. These collagen fibres have a length of 0À001-4À0 mm. The collagen fibre suspension can be caused to penetrate the web with the aid of pressure or suction. The initial web may be woven or non- woven and composed of fibres of nylon, polyacrylate, polyester, polypropylene, wool cotton, viscose or cellulose acetate. The initial web may be needled. The treated web may contain 5-90% collagen fibres. The rolling step may be so as to reduce the web thickness by 5-15%. Before the first rolling the sheet may be contacted with an astringent aqueous salt solution e.g. of sodium chloride or sodium sulphate for at least 30 seconds. After re-aggregation the sheet may be again lightly rolled and have applied to it a second liquid treating agent. The first-treating liquid may be distilled water, acetone and other ketones, methanol, ethanol or isopropanol to bring the pH to the isoelectric range, acetate or phosphate buffer solutions, ammonium sulphate or ammonium phosphate solution, or chrome or vegetable tanning agents. The second liquid treating agent may be binders, softening agents, fat liquors, liquid solutions of dyes and pigments, synthetic rubber and resins e.g. a mixture of a butadiene-acrylonitrile copolymer rubber latex and a melamine-aldehyde resin in aqueous suspension. The sheet can be heated after applying this latter polymer so as to precipitate it in the sheet. The dried sheet can be buffed. Specifications 1,065,911 and 1, 024, 769 are referred to.

Title: Device for speed regulation of direct current motors supplied from  ac mains
IPC: H02P7/293
Filed: 1971-07-27
Abstract: 1359194 Control of D.C. motors HOLZER AG 27 July 1971 [28 July 1970] 35327/71 Heading H2J [Also in Division G3] A D.C. motor energized from an A.C. supply is controlled by an electronic switch fired in response to the difference between a reference voltage and a speed-dependent voltage. The reference voltage signal is applied to a firing pulse generator through a delay circuit. The generator also receives a current-dependent signal. In the embodiment shown, a shunt wound or permanent magnet motor 1 for driving a washing machine, is supplied from A.C. mains 12 by way of a rectifier 11, thyristor 2, and current measuring resistor 9. The thyristor 2 is triggered by a pulse generator 3 receiving a first input U 1  from a reference voltage source 7 and a second input U 2  dependent on the back E.M.F. of the motor 1. The input U 2  may alternatively be provided by a tachogenerator. In operation, the generator 3 triggers the thyristor 2 so as to keep the motor speed at a level determined by the reference voltage. Sudden changes in the reference voltage, e.g. at switch on, which might cause surges, are reduced by a time delay circuit 14, 18 connected between the source 7 and the generator 3. When the circuit is first energized, capacitor 14 is uncharged, and the only input to the generator 3 is provided by a low voltage saw-tooth generator 4 synchronized with the A.C. supply. The mean motor current is limited by a switching device 5 which reduces the difference between voltages U 1  and U 2  if the current sensed by the resistor 9 becomes excessive. In a modification, Fig. 8 (not shown), a rectifier bridge including two thyristors replaces the thyristor 2 so that both half-waves of each cycle are used. A smoothing capacitor is also included.

Abstract: 1458168 Producing low-nitrogen steel USS ENGS & CONSULTANTS Inc 29 Aug 1975 [30 Aug 1974] 35768/75 Heading C7D In a bottom-blown process for refining molten pig-iron having an initial N content > 0À002%, a stream of free-oxygen-containing gas is introduced into the melt at rate R T  in the range 75 to 160 NCF/min/ton where RT = R O  + R S , R O  being the rate of introduction of O 2  and R S  that of the other gases, and RO being # 0À8R T ; thereafter there is introduced at rate # 0À8R T  an inert purging gas while the C content of the melt is # 0À3%, until the N content of the melt has been reduced to <80% of the original level, and then oxygen is introduced at rate # 0À8R T  until the C content of the melt falls below 0.2%. The process may be  used in a Q-BOP type process, wherein O 2  is blown into the bottom of the melt surrounded by a sheath of protective gas, e.g. methane, blown in at rate R p ; in this case RS may be R p  + R A  where R A  is the rate of argon input; this may be substantially zero initially. Then, preferably after the  silicon portion of the blow, R O  is reduced, preferably to zero while RA is increased to R T ; some O 2  may be present in the Ar, however. When the N 2  content has been suitably reduced, R O  is again increased to # 0À8 RT until the C content is reduced as required.

Filed: 1935-12-30
Abstract: 468,365. Vibration-dampers; damping vibrations in aircraft parts, floors, and pipes ; mounting motors. ROUY, A. L. M. A. Dec. 30, 1935, Nos. 36012 and 36013. Convention dates, Dec. 29, 1934 and May 8, 1935. [Class 108 (iii)] [Also in Groups X, XXVI, and XXXIII] Fixed aircraft wings or aircraft supporting surfaces having a limited pivotal movement comprise at least one vibration-damping system arranged so as to destroy the energy tending to maintain the vibrations. The fluid-friction vibration-damper shown in Fig. 2 is preferably arranged at the free end of an aeroplane wing and comprises a mass in the form of a circumferentially-grooved piston 2 which is adapted to reciprocate against the action of springs 1 in a cylinder 7 and to force a liquid or gas through a valve-controlled pipe 8 connecting the ends of the cylinder. To prevent the piston knocking the ends of the cylinder the fluid resistance may be increased, as the piston approaches the end of its stroke, by the closing of the pipeopening by the piston, or the piston or cylinder ends may be formed, for example, of leather. Fig. 5 shows a modified construction fixed inside an aeroplane wing-spar by means of a bracket 21 and tightening collar 22, the springs 1 being of the flattened, double-conical type. Fig. 7 shows the invention applied to an aileron 23, the damping-device being pivoted between the free ends of arms 25 fixed to the aileron and being reciprocable in an aperture 26 in the wing. In another construction shown in plan view in Fig. 4, the mass 4, or members moving therewith, is or are carried by jaws 3 adjustably spring-pressed into frictional contact with guides 5 secured to the vibrating part, the contact surfaces being of steel and guaiacum respectively. It is stated that the energy absorbed by a device according to the invention may be dissipated in any form such as electrical, mechanical, or thermal. The Specification as open to inspection under Sect. 91 describes also means for damping vibrations in floors, particularly on ships. In one form, a member 32, Fig. 11 (Cancelled), projecting upwardly from one floor 34 is adapted to engage between spring-pressed friction plates mounted between cheeks 30 depending from an upper floor 31. The Specification also describes (a) means for damping vibrations in pipes, particularly oil and petrol pipes on aircraft, the connection between the piping and its support comprising relatively-displaceable frictional parts, or the piping itself being formed in a plurality of such parts, and (b) the application of the invention to motors, particularly aircraft motors, as shown in Fig. 5 (Cancelled), in which the motor casing 13 is resiliently connected to a cradle 14 spring-mounted on a support 15, friction or other dampers 17 being interposed between the cradle and support. A spring-controlled inertiamass 2 acting as a vibration-damper is mounted beneath the motor. This subject-matter does not appear in the Specification as accepted.
