Title: Improvements in and relating to thermal power plants
IPC: F02C9/24
Filed: 1948-10-15
Abstract: 663,184. Gas turbine plant. AKT.-GES. FUR TECHNISCHE STUDIEN. Oct. 15, 1948 [Oct. 20, 1947], No. 26879/48. Class 110(iii) In a closed circuit, thermal power plant in which the output may be varied by varying the pressure level in the circuit, working medium from an external source may be introduced into the high and low pressure parts of the circuit or into the low pressure part alone, according to the relation between the content of working medium in the circuit and the full load content, and automatic means is provided to prevent return of working medium from the high pressure part of the circuit to the external source. The gas turbine plant shown comprises a compressor 1, a heat-exchanger 2, a heater for the working medium 3, a turbine 4 and a precooler 6. A reservoir 8 is connected to the intake and discharge of the compressor 1 at the points 11<SP>2</SP>, 12<SP>2</SP>. The output of the plant is varied by controlling the pressure level in the circuit. When the pressure level in the circuit is below a predetermined fraction of the full load pressure and it is desired to increase the output, valves 11' and 12 are opened simultaneously. When the pressure is above this value, the valve 11<SP>1</SP> only is operated A non-return valve 15 prevents leakage from the circuit when the pressure in the reservoir 8 is low. The valve 12 is independently controlled by the governor 16 of the circuit turbine. In a modification, two throttling points are placed in the lines 11, 13. These throttling points are so arranged that the quantities passing into the high pressure and low pressure parts of the circuit are in the same ratio to one another as are the quantities of working medium in the high and low pressure parts of the circuit. In this modification the governor 16 controls a valve on the reservoir regulating the supply to both the high and low pressure parts of the circuit.

Title: Automatic distributor for fluids such as lubricating oil under pressure
IPC: F16N25/02
Filed: 1931-09-28
Abstract: 394,944. Engine and like valve gear. VINCENT, J., GARNIER, (Úpouse VINCENT), S., and VINCENT, C., (Representatives of Vincent, G.), 19, Avenue de Picardie, Versailles, France. Sept. 28, 1931, No. 27003. Convention date, Sept. 27, 1930. Void [Published under Sect. 91 of the Acts]. [Class 122 (ii).] Apparatus for distributing lubricant, or for pumping liquids, consists of two or more units each comprising two pistons, e.g. 19, 21 connected by a rod 20, the end faces of the pistons being acted on by motive fluid, e.g. oil to be distributed, and the annular spaces 24, 25 forming pump chambers. The units move in succession and each unit acts as distributing valve to the unit above it, the uppermost unit controlling the lowest unit through crossed passages. The pump body comprises flat sections held together by bolts 10 .. 13, the bolts 10, 11 passing through the supply passages for the motive fluid and the bolts 12, 13 through the exhaust passages. In the position shown, the piston 20 admits pressure fluid to the space 31 by means of passages 30, 29, 28, groove 27 and passage 26. At the same time the piston 19 connects the space 32 to exhaust by the passages 33, 34, 35, groove 36 and passage 37. The supply to the pump chambers may be controlled by check valves, or by passages controlled by the rods 20 &c. In the position shown, the space 44 is connected by passages 46, 47, a groove 43 and passage 51 to the discharge passage 18 from the driving pistons. A part of the oil may thus be pumped at a higher pressure, or by closing the passage 18, the whole of the oil may be discharged through the pump chambers. Alternatively the motive fluid and the fluid pumped may be different and the various pump chambers may pump different fluids.

Abstract: 695,360. Food for animals. NICHOLLS, A. S., ENEVER, W. B., and CHAPPIE, Ltd. Jan. 10, 1951 [Oct. 25, 1949], No. 27422/49. Class 5(ii) Animal food is made by cooking wet proteinous material composed of meat, fish, offal or other parts of animal carcase, or other forms of animal or fish protein, mixing the cooked product with dietetically suitable proportions of edible materials which are at least superficially dry, composed of biscuits, cereals or other carbohydrate, vegetables dried or otherwise, or pulses, extruding the mixture in the form of hollow tubes through a large number of openings, breaking or cutting the tubes to short lengths, and drying these lengths. The proteinous material is preferably cooked in steam under pressure; the meat or the like is loaded into crates, each of which has a conical tubular insert in the lower part, the crates are covered with conical or dome-shaped covers and placed one above the other in a pressure vessel, steam is admitted to the top of the vessel and is led from the bottom. One procedure involves feeding pressure-cooked proteinous material and dry material into a mixer, passing the mixture to a grinder, conveying the ground mixture in a hot air current for circulation in a cyclone, and therefrom for extrusion as hollow tubes, cutting the tubes as they are extruded, passing the lengths to a hot air pre-drier and to a second cyclone, and then conveying them through a hot air drier to a storage bunker, from which the dried product is filled into cans. The extruder (Fig. 2.) comprises an extruder plate 25 and wearing plate 26 held together at the front end of an extruder barrel 12' by a screwed-on flange 27; a worm 35 carried on a shaft 33 forces mixture through openings 36 in the plates, the tubular form of the extruded mixture being obtained by mandrels 41 supported in the holes 36 on spiders; mounted on the shaft 33 is a rotary knife 37, which cooperates with the plate 26, and a blade 38 which serves to chop off extruded tubes emerging from the openings 36.
