Title: Improvements in and relating to gas turbine power plants
IPC: F02C6/18
Filed: 1950-05-03
Abstract: 706,477. Gas turbine plant. BRITISH THOMSON HOUSTON CO., Ltd. May 3, 1950 [May 17, 1949], No. 10932/50. Class 110 (3). [Also in Group XXIX] A gas turbine power plant comprising a compressor feeding a combustion chamber, a fuel supply regulator to maintain the turbine speed constant and a heat exchanger using the turbine exhaust waste heat, has a throttle valve in the gas flow to vary the pressure ratio across the turbine controlled by the turbine exhaust temperature or the rate of fluid flow from the heat exchanger. The turbine shown comprises a compressor 2 supplying air to a combustion chamber 3 feeding a turbine 4 driving the compressor 2 and a generator 5. The fuel supply to the chamber 3 is controlled by a regulator 8a to maintain the turbine speed constant. The exhaust of the turbine 4 is used to heat a boiler 12. To control the exhaust gas temperature, a throttle 18 may be placed as shown in the turbine exhaust, or in the compressor inlet 6 or in the exhaust pipe 16 of the boiler 12 or two throttles may be used, one at the compressor inlet and the other in the turbine exhaust. The throttle 18 is controlled by a servo motor 22 actuated in response to the turbine exhaust temperature Reduction of this temperature, as measured by the thermometer 36 causes the valve 18 to throttle the exhaust gases and reduce the pressure drop across the turbine. This causes the turbine to slow down and the regulator 8a to supply additional fuel to the combustion chamber which results in an increase of the temperature at the turbine exhaust. In a modification, the valve 18 is actuated by a servomotor controlled by a capsule responsive to the pressure drop in the steam discharge pipe of the boiler.

IPC: F26B11/04
Filed: 1916-08-03
Abstract: 108,358. Prindle, W. E. Aug. 3, 1916. Rotary furnaces; charging and discharging.- Material to be dried is fed through a hopper 27 into a rotating cylinder 1 and after passing through the cylinder is discharged by a transverse conveyer 9, the hot gases from a fireplace 15 being drawn through the cylinder by a fan 31. The hot gases pass through a pipe 17 projecting a considerable distance into the cylinder and open only at the end. Hot air from the chamber 21 also passes into the cylinder through a flue 25 and is admitted outside the pipe 17. The cylinder is divided into five sections. The first section carries a series of helical blades 33 which deliver the material into the various compartments of the second section. As shown in Fig. 2 there are four compartments formed by radial divisions 35. The material is delivered from the compartments to the third section of the cylinder which is provided with lifting plates 38 arranged in staggered relation and then passes to helical blocks 40 disposed in the fourth section. These blades are arranged to prevent the material falling directly in front of the pipe 17 in order to prevent scorching. The fifth section is fitted with lifting plates 41 which deliver the material to a stationary hood 19 in the lower part of which works the discharge conveyer 9. The pipe 19 rotates with the cylinder 1, but communicates with a stationary flue pipe 18. The cylinder 1 turns on rollers 3 and is driven by gearing 6, 7.

Title: Improvements in or relating to reciprocating steam engines
IPC: F01K7/02
Filed: 1932-04-18
Abstract: 400,245. Steam engines. AKTIEBOLAGET GOTAVERKEN, Gothenburg, Sweden. April 18, 1932, No. 11074. Convention date, Feb. 16. [Class 122 (iii).] Compound and multiple expansion engines are reconstructed to increase their output by providing them with turbines driven by the exhaust steam of the engines the output of which is utilized to increase the pressure, volume, or to superheat the steam between the stages of expansion. One or more additional flywheels are employed to allow for the increase in the maximum turning moment so that the existing crank-shaft and shafting may be retained. A low-pressure turbine driven by the exhaust steam operates a compressor to superheat or compress the intermediate steam. A turbine is built into the casing 15 and operates a turbocompressor which is connected through a conduit 17 with the H.P. exhaust, and through a conduit 19 with the I.P. inlet 20. The shaft 9 is provided with a flywheel 10. In marine engines the crank-shaft and the propeller shafting driven thereby may both be provided with flywheels. The steam from the I.P. exhaust may be similarly heated. The exhaust from any of the cylinders may be compressed and supplied to the inlet of the same cylinders. The superheating may be effected in part by flue gases or by resistance connected to an electric conductor supplied from an electric generator driven by the exhaust turbine.

Abstract: 544,341. Vinyl polymerization products. DU PONT DE NEMOURS & CO., E. I. July 4, 1940, No. 11257. Convention date, July 4, 1939. [Class 2 (iii)] Resinous materials are prepared by subjecting to polymerizing conditions a mixture comprising at least one methacrylic acid ester of an aliphatic alcohol the alkyl radical of which contains less than 8 carbon atoms and a 1.3- butadiene, the proportion of butadiene being between 4 and 20 per cent. of the total polymerizable material. Specified esters are methyl ethyl, propyl, isopropyl, butyl, and isobutyl methacrylates, and specified butadienes are 1 , 3-butadiene, which may contain butylene, and 2-methyl and 2 , 3 dimethyl-1 3-butadiene. The polymerization may be carried out on the butadiene dissolved in the methacrylate, or on solutions or aqueous emulsions of the monomers; the polymer emulsions or dispersions may be coagulated by known methods e.g. by the addition of aluminium sulphate, sodium chloride or other salt solutions, free acids such as dilute hydrochloric or acetic 'acid. Solutions of electrolytes, or an excess of an alcohol such as ethyl or butyl alcohol ; alternatively the emulsions may be broken by heating or by freezing. The polymer may be obtained in granular form by carrying out the polymerization in aqueous dispersion in the presence of a granulating agent or piotective colloid with continuous stirring or shaking. Oxidation inhibitors, e.g. phenolic or amine substances such as hydroquinone, naphthylamine or eugenol may be incorporated in the inter-polymers. The interpolymers are soluble in common organic solvents e.g. toluene, acetone, dioxan, butyl acetate and ethylene chloride, but are, insoluble in aliphatic hydrocarbons. The products may be used in the preparation of lacquers, varnishes, adhesives, paints, impregnating or coating compositions, wrapping materials, films, interlayers for safety glass, electrical insulation, and moulded products such as combs, penholders, and knife or umbrella, handles. In examples, butadiene is heated in solution in a mixture of carbon tetrachloride and dioxane, with methyl methacrylate in the presence of benzoyl peroxide and in aqueous emulsion with methyl, ethyl, propyl, or butyl methylacrylates or a mixture of methyl and butyl methacrylates ; in the presence of hydrogen peroxide and the sodium salt of the sulphate ester cf oleyl acetate ; 2-methyl 1, 3- butadiene is similarly treated in aqueous emulsion with methyl methacrylate. In further examples, granular interpolymers are prepared by heating butadiene and methyl methacrylate with or without butyl methacrylate, with vigorous stirring, in aqueous dispersion in the presence of benzoyl peroxide and an interpolymer of methacrylic acid and methyl methacrylate which has been neutralized with sodium hydroxide. Specifications 389,115, 456,442, 485,941 and 497,596 are referred to.

Abstract: 1177359 Correspondence control circuits CATERPILLAR TRACTOR CO 10 March 1967 11391/67 Headings G3R R68 R61 R73 R36H2 R36B2 and R36F6 [Also in Division H3] The speed of a fan in a multiple air-cooled heat exchanger of e.g. an I.C. engine is controlled according to the temperature of the one of the fluids e.g. inlet air, water, oil, circulating in one of the heat exchange systems, whichever is closest to its maximum permissible temperature. The outlet temperature of the fluids in exchangers (12, 16, 19), Fig.1 (not shown), are measured by N.T.C. resistors 23, 24, 26, Fig.2 each connected in series with a resistor 36, 37, 38 across battery 39. Series connected resistors 41, 44 and tapped resistor 42 are also connected across battery 39 to form with each pair of resistors 23, 36 &c. a Wheatstone bridge whose output is fed, via diodes 46, 47, 48 and a common line 57, to amplifier 54 and torque motor 58. If the bridge becomes unbalanced due to a change in value of one or more of the thermistors 23, 24, 26, that thermistor which creates the greatest unbalance will, because the relevant diode will be at a greater voltage than the others, which therefore become non-conducting, control motor 58. In turn the motor drives both hydraulic valve 28, controlling a clutch (31) through which the fan is driven by the engine, and the tap 43 of resistor 42 to re-balance the bridge. In a modification, Fig.3 (not shown), a coil (67) of an electro-hydraulic valve (66) is energized by the output from amplifier (54') and is connected to earth via a Zener diode (68) selected to have a voltage drop cross it equal to that from the amplifier (54') when the resistors are all at the bottom of their temperature ranges.
