Abstract: 601,205. Valve amplifying circuits. O'BRIEN, W. J. Oct. 16, 1942, No. 14526. Convention date, Aug. 5, 1941. [Class 40 (v)] In a high-frequency amplifier means are provided to compensate for changes in the internal capacities of the valve produced by changes in grid bias so as to prevent these changes from introducing a phase-shift in the amplifier. Fig. I shows an amplifier in which the input capacity depends .on the space charge effect and variations are compensated by resistance 8. The output capacity will tend to cause a reactive component of the output voltage to produce a voltage across the resistance 8 which would be impressed on the input, but is balanced out by a phase-opposed voltage through a balancing condenser 23. The gridplate capacity is neutralized by a condenser 25 feeding out of phase voltage to the grid preferably through potentiometer 26-28. In a modification, an additional coupling resistance is arranged in series with the input circuit and is traversed by current derived from the output circuit, Fig. 2 (not shown). Alternatively, the compensating resistance may be included in the plate circuit and the voltage across it fed in series with the input circuit to the grid, Fig. 4 (not shown). Fig. 3 shows a neutralizing arrangement with a divided input circuit in which the plate-cathode capacity is neutralized by condenser 35 and the plate-grid capacity by condenser 36, a second compensating resistance 29 being provided.

Filed: 1955-05-20
Abstract: 800,814. Turbines. PLESSEY CO., Ltd. May 17, 1956 [May 20, 1955], No. 14549/55. Class 110 (3). A turbine overspeed control means comprising an element for the control of the flow of working fluid through the turbine which is moved or held towards the maximum flow position by the output torque of the turbine acting against the action of resilient return means uses the fluidpressure of the working fluid as the force to produce the return movement of the resilient return means. The invention is described with reference to a starter turbine a which is connected to the engine shaft b by an epicyclic gear train consisting of a sun-gear c driven by the turbine, an internally toothed non-rotating outer annulus gear g and planetary gears d. The planetary gears d are mounted in a cage e attached to a shaft f connected through a gear h which will only transmit drive in one direction of rotation to the shaft b. The mass flow of fluid to the turbine is controlled by means of a valve, nozzles fitted with cover-plates or other restrictions or pivoted nozzles through a shaft l carrying an arm m. A slot n in the arm m is engaged by a pin o projecting from the annulus g. A compression spring opposes the torque reaction on the annulus g. At starting, the spring is fully extended and the mass flow controlling means are in the minimum flow position. As soon as the starter turbine commences to rotate, the annulus gear g will apply a load to the spring and the controlling means will increase the mass flow of air. This will result in an increase in torque and further opening of the controlling means. When the engine has started the torque will decrease and the controlling means will then be closed again by the action of the spring j. According to the invention the torque opposing means consists of a fluid-actuated piston or bellows p which is actuated by fluid from a tapping q<SP>1</SP> of the turbine's working-fluid supply line q.
