Abstract: 957,056. Nuclear power plant. SULZER FRERES S. A. Feb. 10, 1961 [Feb. 27, 1960], No. 5147/61. Heading G6C. In a nuclear reactor power plant, superheated steam is pumped through a reactor to a turbine. The liquid condensate from the turbine is vaporized by a separate flow of superheated steam from the reactor output. The vapour is pre-superheated by a third flow of superheated steam from the reactor before entry into the reactor. The pre-superheating may be effected either by a heat exchanger or by the direct mixing of the vapour with superheated steam. As shown, Fig. 1, the turbine 3 is supplied with superheated steam from the reactor 1. The condensate is vaporized at 8 by superheated steam from the reactor output. Wet vapour from 8 is superheated at 12 before entering the reactor through blower 13. In an alternative form, not shown, the heat exchanger 12 is omitted and superheated steam is mixed with the wet steam issuing-from the vaporizer. In a further embodiment Fig. 4, the reactor 1 has three separate cooling zones, the outer of which supplies the turbine 3 while the two inner zones supply superheated steam to the condensate vaporizer 8 and to the vapour to superheat it before entry into 1 or headers 51, 52, 53. The regulator 71 is controlled from temperature sensing elements 65, 66, 67 or flow meter 73 and adjusts the throttle 47, the control rod 76, the blower motor 77 and feed pump 7. The throttle valves 62, 63, 64 controlling the supply of superheated steam to the vapour at the reactor entry are controlled from 65,66,67.

Title: Improvements in or relating to fluid-pressure-operated computers or controllers
IPC: F15C4/00
Filed: 1961-02-13
Abstract: 981,911. Fluid-pressure servomotor control systems. HONEYWELL Inc. Feb. 13,1961 [Feb. 17, 1960, No. 5305/61. Heading G3P. [Also in Division G4]  In a force balance fluid-pressure computer or controller a capsule stack 6 receives an input signal representing a manual setting, a pressure, a temperature or an electrical analogue signal, and acts on a pivoted lever 80 which transmits the force via a pair of movable rollers 92 to a pivoted lever 31 the end of which constitutes a baffle which co-operates with a nozzle 103. The back pressure of the nozzle 103 is fed to a supplyexhaust relay 10 the output pressure signal from which is fed to a feedback capsule stack 5 which acts on a pivoted lever 121 which carries an adjustable member 122 which abuts the lever 31. The rollers 9 are adjustable by manually operable means along the length of the lever 31 and parallel to the pivotal axis of the lever 80. The output pressure signal of the relay 10 is proportional to the input pressure signal applied to the stack 6 and may be used for indicating, recording or control purposes. In another arrangement, Fig. 1, the rollers 9 are moved by a diaphragm motor 7 which receives a fluid-pressure signal. The output pressure signal in this case, is proportional to the product of the pressures applied to capsule stack 6 and diaphragm 7. If the roles of the capsule stacks 5 and 6 are reversed the output signal from the relay 10 is proportional to the quotient of the two input signals. If the output signal from relay 10 is fed back to capsule stack 6 and to the diaphragm motor 7 this output signal is proportional to the square root of the input signal applied to capsule stack 5. The pivot of lever 31 is constituted by horizontal and vertical flexible strips. The member 122 is a nut on a screwed rod carried by a cantilever member the pivot of which is a flexible strip. The pivot of cantilever 8 is also a flexible strip. The pivotable axis of the lever 8 is at right angles to the pivotal axis of the lever 31. The diaphragm motor 7 is connected to the rod 92 carrying the rollers 9 via a universal coupling and the rod 92 is guided by additional rollers 93.

Abstract: 1,165,973. Control of A.C. motors. GENERAL ELECTRIC CO. 3 Feb., 1967 [25 April, 1966], No. 5425/67. Heading H2J. [Also in Division G3] Apparatus for controlling the power supplied to an inductive load 3, which may be a threephase motor, comprises controlled rectifiers 2 interposed between the A.C. source 1 and the load, the gate signals for the rectifiers being in the form of trains of pulses developed by a number of circuits 6, which are simultaneously controlled by a voltage applied at terminals 30 whereby the firing angles of the rectifiers 2 are controlled thus to control the power supplied to the load. Where the load is an A.C. motor the voltage applied at 30 may be a voltage proportional to the speed of the motor, the apparatus then controlling the speed of the motor. Each of the pulse circuits 6 comprise a capacitor 8 which is charged by way of a resistor 22 to a voltage existing at a junction 28, the magnitude of this voltage being controlled by the state of a transistor 26 which is under the control of the voltage at terminals 30. The capacitor 8 is further charged by way of resistors 16, 17 and after a predetermined time a unijunction transistor 7 becomes conductive when the capacitor 8 discharges through the primary winding 9p of a transformer whereby a train of pulses is applied to the gate of rectifier 2 by way of the secondary winding 9s of the transformer. The firing angles of the rectifier 2 are therefore controlled by the magnitude of the voltage at the junction 28 and therefore by the voltage at terminals 30.

Abstract: 1,151,553. Tank wagons loading and unloading by pneumatic conveyers. GENERAL AMERICAN TRANSPORTATION CORP. 3 Feb., 1967 [16 Feb., 1966], No. 5464/67. Headings B8A and BBE. [Also in Division B7] A tank wagon comprises a centre section 41, end sections 42 and end headers 43 providing the only connection between stub draft sills 50 which are connected to the end sections by a saddle plate 51 and pedestal 53, Fig. 1, secured to a body bolster, Figs. 21-23 (not shown). The contents are unloaded from a sump 102, Fig. 16, at the bottom of the centre section through a conduit 130 and a pneumatic conveyer tube 125, Fig. 11, controlled by a valve 160, while loading is effected through a nozzle 60. To load the tank a cap 61 of one nozzle 60 is removed together with the adjacent manhole cover 63 and the load is blown into the tank under considerable pressure, a filter preventing dust escaping from the manhole. To unload, one cap 128 is removed from the tube 125 and this is connected to a receiving bin, and the valve 160 is opened by a cam 168 operated by a shaft 164, thus allowing the material from the sump 102 to rise up the conduit 130 into the tube 125. High pressure air is now connected to a nozzle 120 which enters air chambers such as 109, Fig. 6, of fluidizers at the base of the sections 42 and thus into chambers such as 105, 106, 113, 114 and into the tank to pressurize it. At the top of the tank a dome tube 70 with a relief valve 73 communicates with tubes 131, 132 controlled by valves 137, 138 and when pressure has built up the valve remote from the open end of the tube 125 is opened to cause it to discharge the material. The fluidizing causes the material to flow into the sump 102 until discharge is complete, at which time, to prevent damage to the receiving bin by a bubble effect, the valve 160 must then be shut immediately. This is effected as pressure falls in the chamber 177 of the valve 160 by atmospheric pressure in the chamber 184, producing a pressure difference over a diaphragm 176 to overcome a spring 197 to allow the diaphragm 166 to close the conduit 130 which remains held closed by the pressure difference while it continues.
