Filed: 1939-05-05
Abstract: 528,391. Compound engines ; cylinders receiving liquid fuel. MARTINKA, M. May 5, 1939, No. 13471. [Classes 7 (ii) and 7 (iii)] In a two-stroke engine in which the charging air is compressed and receives heat from the exhaust gases prior to combustion of a fuel therein, the heat exchange between the air and the exhaust gases is effected in two stages, a high - temperature counterflow regenerative heat exchanger within the combustion chamber and a lowtemperature exchanger externally of the combustion chamber. As shown in Fig. 1, the engine comprises a highpressure cylinder 20 and a low-pressure cylinder 26. Air is compressed in a three-stage compressor 11 with inter-coolers 12, 13 and is conveyed by a pipe 14 through a heat exchanger 16 heated by the exhaust from the cylinder 26. From the exchanger 26 the air is conveyed to the cylinder 20, in which it passes through a regenerator 19 consisting of thin plates. Fuel is injected at 21 into the heated air and burns and the exhaust gases escape through the regenerator to the cylinder 26. The pistons in the cylinders 20, 26 are connected to cranks at 180 degrees or less apart, e.g. 120 degrees. The regenerator 19 is arranged as near the cylinder head as possible and may be reciprocated axially of the cylinder, to allow of opening the inlet and exhaust valves, by a toggle linkage actuated from the engine shaft. The regenerator, Fig. 5, comprises a hub 76, curved spokes 77 and a ring 78, with inner and outer rows of laminated metal plates 79, 80, and an outer ring may be welded to the free ends of the plates 80. In a modification, the air from the heat exchanger 16 is compressed in a fourth stage of the compressor 11 and passes through a receiver before entering the high-pressure cylinder 20 ; and a receiver is provided between the cylinders 20, 26.

Abstract: 832,815. Making mats of glass &c. MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE SAINTGOBAIN, CHAUNY & CIREY S.A., DES. April 29, 1957 [May 15, 1956], No. 13541/57. Class 120(3) In a process for making mats from glass and other mineral fibres extended as a tubular web on to a receiver through apertures in a rotating hollow body, at least two jets are directed at the web so that it is dispersed and the fibres deposited on the receiver as a layer of even thickness. In Fig. 1, glass fibres projected through apertures 2 in a rotating hollow body 1, are acted on by two jets 4, 4<SP>1</SP> of gas directed downwardly at an angle of up to 70 degrees and the conveyer is a belt of mesh inclined at 30 degrees moving over an aperture 6 under suction, the arrangement causing the fibres to be more or less parallel to the receiver when they arrive on it. Atomizers 11, 12 of sizing material and a ring 13 of jibs to assist the jets 4 in causing the fibres to descend may also be provided. The jets may be replaced by one or more groups of two and may be set in a horizontal plane being offset from a central position or oscillating uniformly or otherwise over a short path on either side of a central position. Their direction, pressure and output may vary, and where several are used, the respective variations may be in or out of phase and the phases may be staggered. One jet may oscillate and the other be fixed; the oscillating jet may always be directed to the centre of the web, while the latter may be elongated.

Abstract: 727,209. Pumps ; filtering charge ; carburetting-apparatus. LEGROS, R. G. May 14, 1953 [May 29, 1952], No. 13542/53. Addition to 670,933 and 701,022. Classes 7 (2) and 7 (3). The auto-compressor device of the parent Specification for supercharging vehicle &c. engines by the air pressure created by vehicle movement, and comprising a hollow body B with an inlet 1 directed forwardly of the vehicle, a maximum cross-section at least five times that of the inlet 1 and an outlet 2 connected to the engine intake, has the air pressure at the outlet 2 controlled by variation of the flow velocity of air through the inlet 1. As shown, the device has ahead of it a Venturi 18 as described in Specification 701,022, and the inlet flow velocity may be varied by relative axial displacement of the Venturi 18 and body B, by adjustable partial closing of the inlet 1 as by an axially movable cone 35, or by a combination of both means. The cone is moved under the control (a) of a lever 42 manually or automatically adjustable, as into a number of set positions, or (b) of a manometric capsule 52 subject on opposite sides through pipes 53, 54 to the suctions at the Venturi entry 20 or throat 21 and at the inlet 1 respectively so that a position of equilibrium of the cone is automatically obtained for each vehicle speed. In both cases the cone 35 is moved through a rod 36 sliding as in a dust filter 38. The inlet flow velocity may be limited by the air pressure at a point A 0  acting through a pipe 55 on a manometric capsule 58 so as progressively when it exceeds a predetermined value to open a valve 56 against an adjustable spring 61 and so correspondingly destroy the vacuum set up by the pipe 54. Alternatively, the capsule 58 may limit the inlet flow by mechanically moving the Venturi 18 axially. Sleeves 29, 30 connected by ribs 32 guide between them air having an ejector action on air passing between the Venturi 18 and the exterior of the body B.

Title: Improvements in or relating to the manufacture of filaments from vegetable globulin
IPC: D01D10/04
Filed: 1940-08-29
Abstract: 543,586. Artificial filaments. TRAILL, D., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 29, 1940, No. 13600. [Class 2 (ii)] Artificial filaments are obtained by extruding a dilute aqueous alkaline solution of a vegetable globulin into a coagulating bath, withdrawing the filaments at a linear speed exceeding the linear rate of extrusion, subjecting the coagulated but still unhardened filaments, while under sufficient tension to maintain the length at which they were removed from the coagulating bath, to a treatment with sodium chloride solution of a strength at least about equal to that of an aqueous sodium chloride solution saturated at room temperature, until their shrinkage capacity on hardening has been substantially reduced, and then subjecting them to treatment with an aqueous hardening solution while they are in untensioned condition. The hardened filaments may be subjected to further insolubilizing treatments while in untensioned condition. The vegetable globulin used may be obtained from peanuts, hemp-seed, castor oil seed, or soya beans. The treatment with sodium chloride may be carried out continuously with the process of extrusion, and the filaments or filament-bundles may be forwarded in helical manner by means of successive pairs of cylindrical rollers arranged in skew fashion and rotating at the same peripheral speed in parallel planes. The rollers may be immersed in, or may be sprayed with the sodium chloride solution. Instead of rollers there may be used intermeshing cage apparatus for forwarding the filaments in a helical path. After the salt treatment, the filaments may be cut to staple fibre and then hardened in loose condition. In an example, a solution of peanut protein in dilute aqueous caustic soda is extruded through multiple spinnerets into saturated sodium sulphate acidified with sulphuric acid and stretched. The bundles of filaments pass from the bath to a series of skew cylindrical rollers which are sprayed with saturated brine. The bundles are subsequently cut to staple fibre, introduced into brine containing formaldehyde and hydrochloric acid, and then washed. Specification 539,200 is referred to.

Abstract: 1,122,285. Steam turbines. ELLIOTT BROS. (LONDON) Ltd. June 24, 1966 April 1, 1965], No. 13862/65. Heading F1T. [Also in Division G3] A turbo-generator connected in parallel with other machines to an electrical network runs at synchronous speed and the turbine output is maintained at a level demanded by a load demand signal by regulating the flow of steam to the turbine. As shown, a turbine 1 has a nozzle box 3 the flow to which is controlled by valve 6 operated by a servomotor 15. The latter is controlled by a pilot valve 14 which is operated via a floating lever by piston 10. The latter receives oil from a pump 8 via governor valve 9. A beam 24 is responsive at opposite ends thereof to a load demand signal from a servomotor 23 and to a pressure representative of the turbine output. In this case, the latter pressure is that obtaining in the nozzle box; alternatively it could be that in the region of the first stage stator blades. Any unbalance in beam 24 adjusts a spill valve 13 to actuate piston 10 to adjust valve 6 to restore the balance. A dashpot 27 reduces instability in the control loop. A speeder gear 17 has a servomotor 18 which, during the normal running phase of the turbo-generator, is biased so that it only operates to prevent overspeed of the turbine as sensed by the flyball governor 26. This governor system controls the speed of the turbine when the latter is not constrained to run at synchronous speeds. The control system may alternatively be pneumatic or electrical.

Title: Carburettors
IPC: F02M1/02
Filed: 1930-05-06
Abstract: 356,764. Spray carburetters. CARTER CARBURETOR CORPORATION, 2838, North Spring Avenue, St. Louis, Missouri, U.S.A. May 6, 1930, No. 13944. Convention date, July 3, 1929. [Class 7 (iii).] In carburetters having a primary fuel and air mixing chamber and a secondary rich mixture and air mixing chamber there are provided an annular valve slidably mounted on the primary mixing chamber for closing the air inlet to the secondary mixing chamber, a spring-controlled valve for substantially restricting the air supply to the primary mixing chamber to cause flooding thereof for starting the engine, and means for interconnecting the two valves. The main mixing chamber 76 constituted by the casting 22 has a petrol nipple 27 to which fuel passes from the float chamber and there is a well to which air passes through a passage 24. Air to the standpipe is controlled by a valve 64 slidable on the pipe and under spring restraint. Slidable on the pipe 22 is a casting which has a face 36 adapted to close the air entrance to the final mixing chamber 31, and it is provided with restricted openings 73 controlled by a disc valve 60 and having openings 63 in the hood 61 whereby when an engine starts up limited air is admitted. The throttle control valve 29 is interconnected by levers 34, 54 with sleeve 35 on the air valve casting. When starting up the engine the parts are disposed as in Figs. 1 and 4, the relieved pressure of the spring 70 permitting the spring 68 to close the valve 64 so that air is admitted only at the port 24, bleed hole 45 and slightly at 64 and the suction causes fuel to flow up the main jet. As soon as the engine starts, the increased suction raises the disc valve 60 and admits secondary air to adjust the mixture. As the engine warms the choke member 36 is lowered with consequent lowering and opening of the valve 64 whereby the substantially rich mixture in 76 is mixed in 31 with air entering the throat 12.
