Title: Improvements in or relating to vapour generating and vapour heating apparatus and a method of producing low pressure superheated vapour
IPC: F22G5/16
Filed: 1956-11-01
Abstract: 831,203. Steam superheaters. BABCOCK & WILCOX Ltd. Nov. 1, 1956 [Nov. 1, 1955], No. 33365/56. Class 123(3)  Low pressure steam from the steam generating section of a nuclear reactor 11 is superheated by passing it through a number of parallel-connected heat exchangers 12 in indirect heat exchange with high pressure steam from an associated steam generating unit. Each heat exchanger consists of a cylindrical casing having an inlet 10 and outlet pipes 38, 40 for the low pressure steam and containing tubes 24 which carry high pressure steam generated in said unit. The latter consists of an upright furnace 46 fired by burners 48 and lined with water tubes which deliver steam-water mixture into headers 150, 166, whence circulators convey the mixture into a separator drum 20. Ducts 18 lead the separated steam from the drum to the heat exchangers 12 from which condensate returns to the drum through pipes 34. Above the level of the headers 150, 166 a lateral pass 82 conveys combustion gases from the furnace to an outlet duct 186. The side walls, roof and floor of the pass are lined with tubes constituting a secondary superheater section for the low pressure steam which flows through the heat exchanger outlet pipes 38, 40 to the inlet headers 44, 50 of the section and, after flowing through the lining tubes, passes via outlet headers 64, 84 to a mixing header 76. From the mixing header the steam passes to further secondary superheater sections constituted by banks 90-93 of pendent tubes located in the pass 82, the highly superheated steam leaving the unit from a header 106 to flow, for example, to the low pressure stage of a multiple stage turbine. In a modification, provision is made for the separate superheating of two streams of steam at different pressures. Specifications 338,684, 526,825 and 598,141 are referred to.

Abstract: 683,482. Apparatus for placing detonator tubes in carrying plates. STEWART, I F., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 29, 1950 [Dec. 30, 1949], No. 33389/49. Class 9(i) Apparatus for feeding empty detonator tubes into detonator-carrying plates comprises a chain conveyer 1 having chairs 2 in which the plates 3 are seated. Each plate has sockets 4 to receive the tubes 7 from delivery pipes 5, the flow from which is controlled by spring-pressed plungers 8 passing through a beam 10. When electromagnets 11 are energized the beam 10 moves to withdraw the plungers. The delivery pipes are inclined at 10 degrees to the vertical and the bearing surfaces of the chairs 2 are slightly inclined to the horizontal so that an approaching plate 3 does not strike against the lowermost tubes 7 in the pipes. As the plate moves forwards between guides 6 and under the tubes 7, a bevelled corner 17 contacts a detector plunger 15 to operate a switch 16 whereby the electromagnets 11 are energized to withdraw the beam and cause the plungers 8 to slide in bushes 19 and so release the detonator tubes. When the carrying plate passes beyond the pipes, the switchoperating plunger 15 is released and the electromagnets are de-energized, whereupon the springs 12 return the control plungers 8 into engagement with the lowermost tubes 7 in each pipe 5. In a modification, flow control fingers are attached to the beam 10, the bearing surfaces of the chairs 2 are horizontal and the bottoms of the lowermost detonator tubes are supported by the control fingers at a height above the carrying plate 3. As the carrying plates move forwards, the detonator tubes drop into the sockets 4 succeeding tubes, due to their rounded bases and the inclination-of the pipes 5, riding over those tubes already in position to fall into the next line of sockets. Specification 622,527 is referred to.

Abstract: 1,269,409. Central buffer couplings. MINISTERIUM FUR VERKEHRSWESEN. 3 July, 1969, No. 33635/69. Heading B7T. Means operating air-line valves are combined with a central buffer coupling operated by a rotatable shaft 1 and comprise a disc 3 mounted rigidly on the shaft 1, a valve-operating rotatable shaft 2 parallel to the shaft 1 and passing through a cut-out 4 in the disc 3, and a cam 5 on the disc which co-operates with a lever 6 on the valve-operating shaft 2, so that when the shaft 1 is rotated (anti-clockwise as shown in Fig. 1), the cam 5 bears against the lever 6 to rotate the shaft 2 and close the air valve before release of the uncoupling which is effected during further rotation of the shaft 1. Rotation of the shaft 1 may be manual or by a pneumatic piston and cylinder 11 via a lever 15, slidably mounted in the yoke 13 of the piston-rod 16. A contact device (17, Fig. 6, not shown) may be mounted on a support 8 to operate a switch and actuate the cylinder 11 to close the valve in the event of uncoupling.

Title: Improvements relating to control systems for direct current generator-motor sets
IPC: H02P7/34
Filed: 1947-12-19
Abstract: 653,444. Automatic control systems; exciting D.C. motors. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 19, 1947, No. 33669. Convention date, July 30, 1942. [Classes 35 and 38 (iv)] [Also in Group XXXVII] An automatic control system for a directcurrent generator, comprises a control winding for the exciter for the generator which is energized according to the relation between a voltage proportional to a quantity to be controlled and a reference voltage, and having a current overflow circuit fed from a constant voltage source, connected across the control winding so that the control effect is limited to a maximum value determined by the control voltage. The Figure shows the invention applied to a Ward-Leonard system used in a hoisting-machine. The speed of motor 1 is controlled by varying the excitation of generator 2 by means of an armature reaction machine 8, according to the current through the machine's excitation winding 9. Winding 9 is connected across a bridge circuit, to which is applied a voltage from generator 2 through resistance 11, and a constant direct voltage from generator 6 through resistance 10. The speed of motor 1 is thus controlled by rheostat 11, which controls the current through coil 9, the arrangement providing automatic control of the generator 2 voltage and therefore of the speed of motor 1, for any particular setting of resistance 11. The voltage across coil 9 is applied to a rectifier network 14, in opposition to a constant voltage obtained from transformer 15, the arrangement being such that the voltage across coil 9 cannot exceed this constant voltage, whereby the excitation applied to generator 2 is limited to a predetermined value. The excitation of machine 8 may also be varied by auxiliary windings. Winding 17 provides an opposing field proportional to the rate of change of excitation of generator 2, thereby preventing an excessive rate of change. An overload protection arrangement is provided by winding 22 which in conjunction with a rectifying network and a source of constant voltage, provides an opposing field which tends to reduce the excitation applied to generator 2, if the armature current of motor 1 exceeds a predetermined amount. The Specification, as open to inspection under Sect. 91, also includes an additional winding for the machine 8 which is excited by the current from generator 2. This subjectmatter does not appear in the Specification as accepted.
