Abstract: 1433852 Dispersion-strengthened alloys INTERNATIONAL NICKEL Ltd 14 Jan 1974 [17 Jan 1973] 01684/74 Heading C7D A wrought dispersion-strengthened alloy product having a microstructure consisting of coarse, elongated grains is produced by hot working a body of alloy powder (e.g. mechanically-alloyed powder) containing a refractory dispersoid to form a consolidated body, heating to cause grain growth, and subsequently hot working. The first hot working stage results in a product having grains which have dimensions not exceeding 10Á on average, and an aspect ratio of the elongated grains of less than 8:1; the hot working may take the form of hot extrusion, hot pressing or hot-rolling, with subsequent forging, swaging or rolling if necessary. The final hot working stage results in an aspect ratio greater than 8:1, e.g. up to 64:1. The heat treatment is carried out at a temperature close to the melting point such that the minimum grain dimension is > 10Á. The process is suitable for Ni and Co-base superalloys, e.g. an alloy of the following composition Suitable refractory dispersoids include the oxides, carbides, borides and nitrides of Y, La, Th and the oxides of Zr, Ti, Ce, Be, Al, the initial grain size being < 1Á. Other alloys which may be formed contain at least 25 wt. per cent of one or more of Co, Ni and Fe, up to 10 vol % of refractory and various stated ranges of one or more of Cr, Al, Ti, Mo, W, Nb, Ta, Cu, V, Mn, C, Si, B, Zr, Mg, and Hf.

Title: Improvements in time base circuits for cathode ray tubes
IPC: H03K4/86
Filed: 1944-02-03
Abstract: 579,682. Saw-tooth generators. STANDARD TELEPHONES & CABLES, Ltd., and HILTON, R. Feb. 3, 1944, No. 1976. [Class 40 (v)] [Also in Group XXXVI] In a trigger-operated time-base circuit, the slow scan precedes the flyback. A positive triggering signal applied to the grid fires gasfilled triode V3, the resulting voltage drop over cathode resistances R8, R9 raising the screen grid voltage of normally non-conducting pentode V2 to a value determined by neon stabiliser N1. Valve V2 conducts, charging condenser C1 at a constant rate dependent on the setting of potentiometer R1. When the voltage across condenser C1 reaches a value, determined by the setting of potentiometer R5, gas-filled triode V1 fires, discharging condenser C1 and giving a negative impulse over coupling condenser C2 to extinguish valve V3, thereby cutting off valve V2, the voltage across condenser C1 falling to the extinguishing potential of valve V1. A brightening-up pulse is supplied to the grid of the cathode-ray tube during the time base sweep. A buffer amplifier may be inserted between valves V1 and V3 and neon N1 replaced by a hard valve limiter.

Filed: 1916-02-11
Abstract: 102,183. Briggs, R. Feb. 11, 1916. Miners and like safety lamps; lanterns, regulating air supply to. - A closed lamp, such as a miner's safety lamp, is adapted for estimating the purity of air as regards non - inflammable gases, such as black-damp or carbon dioxide, by the provision of an air-inlet tube A having an adjustable throttling-device and a scale for indicating the point at which the flame is extinguished. The throttling-device consists of a rod R and an internally threaded tube T engaging an external screw-thread on the tube A, the diameter of the rod R being slightly less than the internal diameter of the tube T. In use, the lamp flame is reduced to about half its normal size, and all air inlets are closed except the tube A. The tube T is advanced by rotating it on the tube A, until the light is extinguished, and the percentage of black-damp or of oxygen in the air is then indicated by the position of an index-mark i with regard to the scale D. The invention is shown as applied to an Ashworth-Hepplewhite-Gray lamp, the tube A taking the place of one of the ordinary air-inlet tubes B. One of these tubes B may be provided with an opening C, over which the thumb is placed during the test, the thumb being removed when the flame is on the point of extinction.
