Title: Improvements in and relating to control systems for prime movers
Inventor: CORBETT JAMES PATRICK
IPC: H02P23/00
Filed: 1954-04-02
Abstract: 776,160. Automatic speed control systems. ENGLISH ELECTRIC CO., Ltd. April 1, 1955 [April 2, 1954], No. 9734/54. Class 38 (4). [Also in Group XXXVII] In a speed control system for a prime mover, an induction motor controlling the fuel valve is energized by the output of a magnetic amplifier system responsive to the rotational speed. The speed-responsive output of a tachometer generator 12 associated with a steam turbine 10 is applied to a tuned circuit 13 operating below resonance on a substantially straight portion of its characteristic. The output of circuit 13 is applied over a rectifier 14 to control a magnetic amplifier 15, which in turn controls a bridgetype magnetic amplifier 16 connected in two phases of the three-phase supply to an induction motor 18 from a source 17. The input to amplifier 16 governs the relative impedances of windings a, a and b, b and hence the speed and direction of rotation of motor 18. The latter repositions a lead screw 19 controlling a fuel valve 11 through a fluid servo system 21, 22, 23, the latter incorporating an automatic follow-up by connection of its pilot valve 22 to piston 23 through link 21. The movement of screw 19 repositions a potentiometer 25 incorporating a speed reference, so that under quiescent conditions the voltage fed back to amplifier 15 compensates the speed signal from tuned circuit 13. A feedback signal representing the induction motor speed is derived from a tachometer 26 and applied over a rectifier 30 to amplifier 15. A second feedback signal representing the rate of change of the output of amplifier 16 is also applied to amplifier 15 over a phase-sensitive rectifier 27, a damping transformer 28 and a " push-pull " magnetic amplifier 29. In a modification, Fig. 2 (not shown), the circuit 13 is replaced by a unit comprising a tuned circuit incorporating a variable inductor whose core may be positioned by movement of a manual screw 33 and the lead screw 19 to provide follow-up. A referecne voltage is separately applied to amplifier 15. The Specification states that (1) the potentiometer 25 may be replaced by an inductive selsyn associated with a rectifier; (2) a differential speed signal may be applied to amplifier 15 over the rectifier 34, damping transformer 35 and amplifier 36 of the system shown in Fig. 2; (3) the fluid servo may be dispensed with if the fuel valve is of the balanced type.

Abstract: 828,005. Cathode materials and processing. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 12, 1958 [March 26, 1957], No. 9805/57. Class 39(1). [Also in Group II] A method for depositing caesium on a surface, for example to form a photocathode, comprises the steps of absorbing caesium vapour in hot zirconium, cooling the zirconium and placing it adjacent the surface and then reheating the zirconium to release the caesium and deposit it on the surface. The zirconium may be in the form of a filament 10 in a side tube 5 of a glass envelope 1 having a surface 2 on which a photocathode is to be formed, the vessel being evacuated through valve 6. The filament may be heated electrically by means of extensible leads 16, and with valves 4, 6 closed, caesium vapour, obtained by heating a mixture of caesium bromide and calcium in boiler 9, is admitted through valve 8 and is absorbed by the filament. After closing valve 8 the filament is cooled, valve 4 opened and the filament placed in position 15 adjacent surface 2, the caesium being deposited on surface 2 when the filament is again heated. A shield 12 may be provided and parts of the envelope heated or cooled to limit the deposition of caesium to the required area.

Abstract: 828,914. Extrusion machines. UNITED STATES RUBBER CO. March 29, 1956 [June 20, 1955], No. 9832/56'. Class 87(2) [Also in Group II]  Plastic stock, e.g. raw rubber, is milled between an elongated screw 13 and an adjacent, oppositely rotating, shorter roller 15 of larger diameter, and is then fed by the screw through a closely surrounding cylinder 11 to an extrusion die 12. The axes of screw and roller are in the same horizontal plane. A hopper 10 partly encloses the part 45 of the screw opposite the roller, but leaves it exposed over an arc of at least 105 degrees. The bearings for the ends of the roller are adjustable laterally by screws 39, 40. Screw threads 33, 34 at the ends of the roller force back any stock tending to be pushed into the bearings. A heat-controlling fluid may be circulated through a jacket 16 in the cylinder 11, through the walls of the hopper 10 and through a space in the roller. The root diameter of the screw thread may decrease in the direction of extrusion opposite to the roller, and increase within the cylinder 11. Another roller may be supported in the hopper by a forked lever, and be urged downwardly by the piston of a pneumatic cylinder, to maintain the rubber inplace in the feed area. Specification 770,705 is referred to.
