Abstract: 719,047. Granulating metals; alloys. BERK & CO., Ltd., F. W. Jan. 27, 1953, No. 2351/53. Classes 82 (1) and 82 (2)] A process for the manufacture of metal powders substantially free from oxygen comprises subjecting a downwardly flowing stream of molten metal to the action of an annular and conical jet of aqueous liquid, the velocity of which is at least 60 ft. per sec., in an atmosphere of an inert or reducing gas which is under a sufficient pressure to balance the tendency of the jet to suck air into the system. The metal may be ferrous including alloys of Fe with Cr, Si, A1 and Ti, Cu and Cu-base alloys such as Cu-Pb, Pb, Sn, Al and Al-Mg alloys, Zn, brasses, bronzes, Cr, Ni and alloys thereof. The liquid may be water which may have dissolved in it up to 1 per cent. by weight of oxidation inhibitors such as sodium benzoate, sodium bichromate, sodium arsenite or ammonium chloride. The gas may be N 1 H 1  cracked NH, or argon. The pressure may be less than 60 inches of water above atmospheric pressure. In the form shown, molten metal 2 in a tundish 3 with a central hole 4 is heated by an electric heater 5, and water is jetted by nozzles 7 into a gas-tight chamber 10 having an inlet 11 for non-oxidizing gas, a water inlet 12, pressure gauges 13 and 18, an oxygen indicator 14, an overflow pipe 15, an outlet pipe 16 and a balancing pipe 17. A small excess pressure of not more than one inch of water may be obtained by filling the chamber 10 with water, allowing some of it to flow out and be replaced by a non-oxidizing gas, and then admitting more water to compress slightly the non- oxidizing gas. The Specification describes the treatment of four alloys with the following percentage compositions:-(i) stainless steel containing 17-12 Cr, 9.32 Ni, .21 Si and 68.1 Fe; (ii) a Cr-Ni alloy containing 74.23 Ni, 21.18 Cr, 2.44 Ti, .63 Al and .45 Fe; (iii) a Ni-Cu alloy containing 67.0 Ni, 30.0 Cu, 1.4 Fe and 1.0 Mn; and (iv) a Cu Pb alloy containing 70.05 Cu, 29.31 Pb, .09 Sn and .09 P.

Title: Improvements in and relating to fluid control valve devices
IPC: F15B13/04
Filed: 1953-01-30
Abstract: 742,596. Manually-actuated valves. BENDIX AVIATION CORPORATION. Jan. 30, 1953 [Feb. 28, 1952], No. 2780/53. Class 135. A valve device for controlling the supply and exhaust of pressure liquid to and from a doubleacting motor, comprises a body 37 having inlet and outlet ports 24, 30 connected by first and second passages 38, 40 having intermediate their ends motor ports 16, 18 connected to opposite ends of the cylinder 14 of a doubleacting hydraulic motor 12. In each passage are mounted normally open valves each comprising valve seat 46 and co-operating valve member 50 located between the inlet and motor ports and a valve seat 48 and co-operating valve member 52 located between the motor and outlet ports. Each valve member 50 engages a spring-loaded plunger 64 having equal effective areas at its ends, which areas are equal to the areas of the seats 46, 48. Each plunger has an axial passage 79 and its rear face connected by a restricted passage 80 to the space between the seats 46, 48, so that the pressure prevailing at the motor port is transmitted to the rear of the plunger and to the space behind the valve member 50 to hold the plunger and the valve member in hydraulic balance with respect to each other irrespective of whether the valve member 50 is seated or unseated. Each valve member 52 engages an equal-armed balance beam 56 pivoted on the body and manually operable by a lever 84. In the neutral position of the lever all the ball valves are unseated, as shown. On, e.g., clockwise movement of the lever, the left-hand ball 52 and right-hand ball 50 are seated and the other balls unseated to direct pressure liquid to the upper end of the cylinder 14 and exhaust it from the lower end. In this case the applied manual effort is resisted by hydraulic force acting on the left-hand ball 52; the left-hand ball 50 and both right-hand balls seat together with both plungers being in hydraulic balance so that the right-hand balls are urged downwardly by spring force. In a modification, so that the hydraulic force resisting movement of the lever 84 may be proportional to the force applied to the hydraulic motor the effective areas of the valve members associated with the non-piston-rod end of the cylinder 14 are increased relative to the areas of the valve members associated with the piston-rod end of the cylinder, the ratio of the areas of the two sets of valves being made equal to the ratio of the effective areas B, b on opposite sides of the piston..

Title: An improved process for the decalcification of mixed calcium and magnesium carbonate materials
IPC: C04B2/10
Filed: 1931-01-28
Abstract: In the treatment of calcined dolomite, magnesian limestone, or artificially produced mixed carbonates of calcium and magnesium with an ammonium salt solution to remove the calcium, a dilute solution of the extracting agent is used.  A solution of ammonium acetate, nitrate, or halide in concentration not exceeding 18 per cent may be employed, a 10-15 per cent solution of ammonium chloride being preferred.  Reaction may be effected in a closed container to keep the liberated ammonia in solution, and after filtration from residual magnesia, treatment with carbon dioxide precipitates calcium carbonate and regenerates the ammonium salt.  When treating material containing say 5 per cent of iron, aluminium, silicon, and manganese compounds calcination of the residue of magnesia yields a refractory material adapted for furnace usage.ALSO:Mixed carbonates of calcium and magnesium such as dolomite are calcined and their calcium content extracted with a dilute solution of an ammonium salt solution such as the chloride.  When the residue of magnesia contains say 5 per cent of iron, aluminium, silicon, and manganese compounds, further calcination thereof yields a refractory material adapted for furnace usage.

Title: Bivalent-signal transmission system
IPC: H04L25/49
Filed: 1974-01-22
Abstract: 1415821 Selective signalling PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 Jan 1974 [12 Feb 1973] 02853/74 Heading G4H In a transmission system (e.g. for personal paging), a series of split-phase Manchestercoded bivalent information signals (e.g. an address) is transmitted, directly preceded by a synchronization signal which has a first signal level for a period of time corresponding to at least three successive half bit times of the information signals and has a second signal level, different from the first, for a subsequent period of time also corresponding to at least three half bit times of the information signals. In the transmitter, a first ring counter is driven by bit frequency clock pulses to gate clock pulses with twice the bit frequency to drive a 6-position second ring counter to produce the sync. signal in D.C. form from a 6-input OR (with 3 invert inputs) responsive to the 6 stages of the second counter. Then the first ring counter gates address bits in turn to a modulo-2 adder, also receiving the bit frequency clock pulses, to convert the bits to D.C. split-phase form. The D.C. sync. and address signals are used to frequency-modulate a carrier and transmitted by radio to the receivers. At a receiver, the signals are demodulated and passed to a split-phase decoder, a clock regenerator and a sync. recognition circuit, all in parallel. The clock regenerator uses a phase loop and clock generator to produce a synchronized clock pulse train at twice the bit frequency which is used to feed a divide-by-2 circuit and (in the sync. recognition circuit) shift a 6-bit shift register receiving the sync. signal. A gate responsive to the register stages recognizes the sync. signal to reset the divideby-2 circuit and control an address store. The divide-by-2 circuit controls the split-phase decoder and the address store. The address store holds the address of the receiver and this is compared with the transmitted address from the split-phase decoder, to give a yes/no output.

Abstract: 781,841. Heating air and water. METROMATIC MANUFACTURING CO., Inc. Jan. 30, 1956, No. 2905/56. Class 64(3) A furnace which supplies both hot water and heated air in cold weather and only hot water in warm weather comprises a main housing 10 divided by a horizontal partition 16 and a vertical partition 19 below the latter into an upper chamber 36 and two lower chambers 20, 21. Rectangular ports 17, 18, in the horizontal partition 16 connect the lower chambers to the upper one, and are controlled by dampers 22, 23 hinged to that partition. A. heating unit 37, a water drum 38 supported on it, and associated partitions 49, 50, 51, 52 extending from the ends and bottom of the unit to the front and back walls, are mounted in the upper chamber 36 so as to divide it into an inverted U-shaped air passage the limbs of which communicate with the rectangular ports. Vertical ducts 48 in the heating unit communicate at the top and bottom with the air passage. The heating unit comprises an oil-fired combustion chamber 40 connected to a smoke box 45 with an outlet 46 by three ducts which are separated by the vertical ducts 48. In cold weather the dampers are in the positions shown so that the rectangular ports are open. A fan 33 in a front compartment of a side casing 100 draws air from an inlet 31 through a filter 35, and delivers it to the bottom chamber 20. The air then flows through the passages in the upper chamber to the other bottom chamber 21, and passes through an opening at the back of the vertical partition 19, through the rear of the chamber 20 behind the damper 22 into a rear compartment in the casing 100 which has a delivery outlet. The-hot gases in the heat exchanger heat the air and the water in the drum, and the latter gives up heat to the air. During warm weather, the rectangular ports are closed by raising the dampers 22, 23 by rotating a shaft 24, which is connected to the dampers by a radial arm 27 and toggle links 26 respectively. The upper chamber 36 is then closed, and the heat exchanger heats the water only. Cool air delivered by the fan 33 into the chamber 20 passes directly into the rear compartment in the side casing 100. The water drum may be provided with external water tubes, which may be finned, to increase the heat exchange with the air. The fan motor is controlled by a room thermostat and the burner 41 by a thermostat 58 at the side of the water drum.
