Title: Reaction propulsion engine and method of operation
IPC: F02C7/08
Filed: 1973-01-23
Abstract: 1392781 Jet propulsion engines TEXACO DEVELOPMENT CORP 23 Jan 1973 3307/73 Heading F1J The invention relates to a jet propulsion engine suitable for use at hypersonic speed in which the ram air at the engine inlet is cooled by indirect heat exchange with fuel, the fuel being subsequently expanded in a turbine which is utilized to drive an air compressor. The engine shown comprises a casing 12 having at one end a ram air intake 14 and at its other end a propulsion nozzle 16. An indirect heat exchanger 18 is disposed in the air intake and fuel is supplied from a tank 20 to the heat exchanger by means of a pump 24. Heated fuel discharges from the heat exchanger through line 28 to a control valve 30 from which it may be directed through line 32 and nozzle 34 to turbine 36, the fuel discharging from the turbine passing under control of valve 62 to injectors such as 68a, 72a into the combustion chamber 42. The turbine 36 drives an air compressor 52 through shaft 50, air from the compressor passing to the combustion chamber 42. The gases from combustion chamber discharge through the propulsion nozzle 16. A regenerative heat exchanger 40 is disposed in the combustion chamber 42 and preheated fuel from the heat exchanger 18 may be passed through control valve 30 and line 38 to the regenerative heat exchanger 40, returning through line 44 to the control valve and thence passing with fuel pre-heated in the heat exchanger 18 to the turbine nozzle 34. Pre-heated fuel from the heat exchanger 18 may also be passed through control valve 30 and line 46 to a nozzle 48 disposed at the downstream end of the combustion chamber. The fuel control valve 62 comprises a rotatably mounted plate formed with two sets of orifices whereby fuel may be passed to injectors such as 68a at the upstream end of the combustion chamber or to injectors such as 72a at the downstream end of the combustion chamber, or to both injectors such as 68a and 72a. Suitable fuels are hydrogen and hydrogen-bearing compounds such as ammonia, methyl alcohol, ethyl alcohol, methane, ethylene glycol and cyclohexane.

Abstract: 690,771. Filters. GENERAL MOTORS CORPORATION. Feb. 13, 1951 [Feb. 14. 1950], No. 3436/51. Class 46 A filter unit comprises a sheet of filter material folded to form a plurality of double-walled filter sections, the walls of each section being in contact and the filter sections being spaced apart by rounded or squared intermediate inner folds, and the sections being arranged into two longitudinal rows with a central longitudinal passage between them. As shown in the Figure (which is a horizontal cross-section) unfiltered liquid passes through a perforated cylindrical cover 46 of heavy paper into the spaces between filter sections 36 formed of contacting portions of a strip 34 preferably of resin-impregnated paper, and through the material to the contacting surfaces. The material is sufficiently rough to permit flow between the surfaces in contact, the filtrate by this means reaching the outer sides of partitions 18 kept apart by bosses 24 on their inner surfaces. The filtrate passes through perforations in the partitions 18 to a drainage passage formed by oppositely-disposed channel portions 26 and leaves by an aperture 16 in a lower plate 14 or by a similar aperture in an upper plate (not known). The upper and lower edges of the filter sections 36 and of the cover 46 are sealed to the plates, e.g. by a resinous compound The ends of the strip 34 are joined at 44 by adhesive. In a modification the folds 42 conform closely to the shape of the partitions and the partitions are spaced by bosses on one member only.

Title: Improvements relating to tin plating baths
IPC: C25D3/30
Filed: 1943-03-03
Abstract: 564,488. Tinplating. CROWN CORK & SEAL CO., Inc. March 3, 1943, No. 3531. Convention date, July 11, 1942. [Class 41] The tin content of a sodium stannate bath for continuous plating of metal strip, wire, &c. is maintained constant without addition of the stannate by maintaining in the bath an amount of alkali effective to produce a constant balance between the anode loss and the cathode deposit,. the anode and cathode current densities being equal and of the order of 35 amps./sq. foot. The bath contains a foam-producing agent to prevent spraying of the plating solution due to rising gas bubbles. To prevent the formation of spongy deposits, one anode of a heavy metal, for instance iron, is employed in addition to the tin anodes. Caustic soda is the preferred alkali employed in the bath, but may be replaced wholly or in part by the orthosilicate, orthophosphate, or sulphide of sodium. Sodium cyanide may be added to promote corrosion of the anodes ; sodium acetate and an oxidizing agent such as hydrogen peroxide may also be present in the baths. Reference has been directed by the Comptroller to Specification 338,488, [Class 41].

Title: Improvements in the manufacture of salts of chrome
IPC: C01G37/04
Filed: 1924-02-16
Abstract: A chromium ore such as chromite is first treated as by heating with carbon or hydrogen to reduce the metals, and the reduced material is then heated with dry gaseous hydrobromic, hydrochloric, hydrofluoric or hydriodic acid so as to volatilize the ferrous halogenide, which is collected.  The remaining material is then further treated with free halogen to obtain the chromic salt.  The chromium salt may be treated with sulphuric acid to obtain the sulphate and recover the halogen acid or may be treated with a current of air, oxygen or ozone, preferably mixed with some chlorine at 300-500 DEG  C. to obtain chlorochromic acid which is passed through a tube heated to a low temperature to obtain chromic acid or at a higher temperature to obtain chromium oxide, and in each case to recover the hydrochloric acid; or it may be passed into water to obtain chromic and hydrochloric acids. If the chromium ore contains magnesium the chromium chloride produced may be quickly washed with water to remove the magnesium chloride.  The ferrous chloride obtained is heated in a stream of oxygen or ozone to obtain ferric oxide and recover the halogen.

Abstract: 432,916. Walls; columns; beams. LUSH, N., Little Studley, Spring Bank, Ripon, Yorkshire. Feb. 8, 1934, No. 4167. [Class 20 (iv)] Relates to methods of forming a joint between a pre-cast reinforced concrete pillar and a pre-cast concrete foundation or between one or two pre-cast reinforced-concrete pillars and two or more reinforced concrete beams. The joint between the pillar 1, Fig. 3, and the foundation 6 is formed by supporting the pillar on an indestructible support 7, such as a brick or rib formed on the foundation, outwardly splaying the reinforcement 2 which projects from the lower end of the pillar, and then enclosing the projecting reinforcement, support, and lower end of the pillar in concrete or the like 11. The reinforcement 2, which may be connected with looped reinforcement projecting above the foundation 6, comprises longitudinal rods tied together by wires 3, Fig. 1, which are cut to permit splaying of the reinforcement as shown in Fig. 3. The foundation 6 is cast in a cube-shaped excavation, and at the same time the foundations of the walls 4 are cast up to the lines XX, Fig. 3, and the jointing concrete 11 is later filled in so a to complete the foundations. Corner pillars are provided with the splayed reinforcement projecting from all four sides. The joint between one or two pillars 12, 13, Fig. 8, and two or more beams 15 is formed by arranging these members so as to form a permanent box-shaped space between the plane ends of the members, connecting the projecting reinforcement of all the members inside the said space, and filling the space with concrete 16. The longitudinal beams 15 are supported on the pillar 12, and the pillar 13 is supported about 3 inches above the upper faces of the beams 15. The pillar 13 is temporarily supported by means of a plank 14 which rests upon the foundation and is tied to the pillars 12, 13. The concrete 16 is cast between the ends of the members 12, 13, 15, the plank 14, and a timber board disposed at the side opposite the plank 14. The end of a timber lateral beam mav be inserted in a slot 18 of the pillar 12 before the concrete 16 is cast. Alternatively, a concrete lateral beam may be supported on the upper edge of the pillar and serve to complete the mould space for the concrete 16. The upper edges of the concrete 16 are inclined as shown at 17, Fig. 8. Timber beams may be used in place of reinforced concrete beams and provided with projecting wire cleats for connection with the projecting reinforcement of the pillars. Where the beams are to be arranged at an angle to each other, they may be provided with suitably inclined plane ends so as to form the permanent casting box. The pillars and beams are adapted to form the open framework of a building.
