Title: Improvements in or relating to methods of reducing ores to obtain ferro-alloys
IPC: C21B5/02
Filed: 1926-08-30
Abstract: 303,207. White, A. E., (Allen, S. G.). Aug. 30, 1926. Alloys.-A method of producing ferro-alloys, for example ferro-manganese, in the blast furnace consists in increasing the ratio of ore to fuel to ensure efficiency of operation in the shaft section of the furnace and simultaneously ensuring efficiency in the smelting zone by so enriching the blast with oxygen that the temperature of the exit gases from the furnace is between 250‹ F. and 400‹ F. and is preferably about 300‹ F. If more oxygen is used in the blast, the detrimental effect of such oxygen is obviated by introducing additional oxygen such as air or oxygenated air at a point or points above the mantle.

Title: Protecting system for electronic valves
IPC: H03F1/54
Filed: 1950-08-31
Abstract: 696,430. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 31, 1950 [March 9, 1950], No. 21493/50. Class 40 (vi). An electronic valve 10 is protected against excessive current by connecting in parallel with it a gas discharge tube 52 which is fired by a voltage derived from the excessive current flowing through fault detecting means in series with the valve and the source of supply, and so short-circuits the valve. As shown, the discharge tube, which may be a thyratron or an ignitron, is fired by means of a voltage applied to its grid and developed across the cathode resistor 30 of the valve, and a choke 24 or a resistor prevents the excessive current of the valve 10 from lowering the anode potential of the discharge tube below the firing point. The circuit affords protection of the valve during the short period before the circuit breakers operate. Specification 696,431 is referred to.

Abstract: 189,186. Annison, R. H. Aug. 17, 1921. Casting and moulding in situ.-Apparatus for the continuous supply of cement grout, concrete, &c. in the construction and repair of structures consists of one or more cylinders each having a piston operated by fluid pressure, and one or more mixing pans located above and supplying the cylinders. In the form shown in Fig. 1, the two cylinders act alternately as operating and pump cylinders, and the valves may be operated by hand or automatically. On opening the valve 18 and exhaust valve 24 of the cylinder 10, and the inlet valve 23a of the cylinder 10<a>, the piston 19<a> is driven outwards and material is discharged through the port 26<a>. At the same time, fresh material is drawn into the cylinder 10, and at the end of the stroke the operations are reversed and material is forced out through the port 26 to a common delivery nozzle. Fig. 8 shows a modification in which a separate doubleacting fluid-pressure cylinder 32 is placed between two double-acting pump cylinders, all three pistons being on a common rod. One pump cylinder may be omitted. In a further modification, a single cylinder has a piston 30, Fig. 6, moving freely therein or guided on a fixed rod 32 ; at each end are valves and ports for the supply and discharge of both operating fluid and material pumped. Cement &c. is fed by gravity through the valve 18 when the piston 30 is at the righthand end. The two-way valve 23a is then opened to admit the operating fluid, preferably steam or compressed air, and so discharge the material through the port 26. The operating fluid then exhausts the valve 23<a>, fresh cement is admitted by gravity at the right-hand end, and so on. For water pressure, exhaust valves such as 24, Fig. 1, are provided. The apparatus may be mounted on a motor chassis or railway truck and be driven from the propelling motor or by electrical means.

Abstract: 1,015,559. Piezoelectric elements; semiconductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 28, 1964 [May 28, 1963], No. 22135/64. Headings H1E and H1K. [Also in Division H3] An elongated piece of semi-conductive piezoelectric material (preferably a single crystal) has spaced PN junctions which when biased induce depletion layers around them to act as electrical/  mechanical transducers for propagating ultrasonic waves down the body. Suitable materials are cadmium sulphide, cadmium selenide, cadmium telluride, zinc oxide, indium arsenide, indium antimonide, gallium phosphide and (especially) gallium arsenide. In Fig. 1 the material comprises a P-type circular filament 10 with N-type regions 13, 14 at each end formed, e.g. by diffusion or epitaxial deposition. The filament may be coiled to save space. The junctions 15, 16 are biased by batteries 24, 27 to produce depletion layers which are a half-wavelength long at the working frequency, which may be 300 Mc/s. to several thousand Mc/s. Pulses applied from a source 30 produce stresses in the depletion layer 11 which cause longitudinal stress waves to be propagated down the line to the corresponding layer 14 at the other end. Here the waves generate corresponding electric signals which are passed to a utilizing device 33. Since the depletion layers and the rest of the material have the same geometry and mechanical properties, their mechanical impedances will be the same and no energy loss occurs. Losses due to reflections at the ends of the material are minimized by tapering the ends 17, 18 and enclosing them in absorbing blocks of plastic 19, 20. The material may alternatively be in the form of a flat ribbon (Fig. 2, not shown). The cross-section of the material may be greater or less than the wavelength of the stress wave, or in the case of the ribbon one dimension may be greater and the other less.
