Patent GB-778941-A (GB)
Title: Improvements relating to power plant including a nuclear reactor
Inventor: ECCLES WILLIAM
IPC: F22B1/02
Filed: 1954-02-08
Abstract: 778,941. Power-generating systems; steam turbines. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 4, 1955 [Feb. 8, 1954], No. 3657/54. Classes 110 (3) and 122 (3). [Also in Group XIII] In a power generating plant in which a heat carrier fluid is heated by a nuclear reactor and flows in a closed cycle inclucing boiler plant wherein heat is transferred from the heat carrier to motive fluid, e.g. water/steam, for a prime mover, the temperature of the carrier fluid returned to the reactor is maintained substantially constant under varying prime mover loads by controlling the temperature of the motive fluid in the boiler plant to thereby control the rate of heat transfer. In the embodiment shown the heat carrier is circulated by a pump P1 through three cascaded boilers operating at successively lower pressures and each having an economizer, an evaporator and a superheater, the heat carrier flowing from the reactor first through the superheater, H.P.S. &c. and then through the evaporators H.P. EVAP, &c., and the economizers HPE &c. alternately. Steam passes from the superheaters to respective stages of a steam turbine via safety valves 1, 2 and 3, relief valves 4, 5 and 6, and speed governor controlled inlet valves 7, 8 and 9 respectively. When the turbine load falls its speed increases and the governor closes valves 7, 8 and 9 causing the boiler pressure to rise until the safety valves 1, 2 and 3 operate and pass excess steam to the next lower pressure stage, the L.P. steam being discharged into the condenser. When the turbine demand exceeds the steam available the relief valves 4, 5 and 6, which are back-pressure valves, operate to prevent steam passing to the turbine. By these means the pressure in each boiler is maintained at a predetermined level so that the rate of heat transfer in the boiler plant is substantially constant. The temperature of the heat carrier leaving the boiler plant may be controlled by (1) bypassing some of the feed water flowing to the low-pressure economizer L.P.E. by means of valves 10 and 11, (2) varying the setting of valves 3 and 6, and (3) varying the temperature of the feed water leaving the turbine plant. The latter may be achieved by varying the condenser vacuum or the flow of cooling water or controlling the amount of feed heating steam passing through valve 22 or when bled steam feed heaters are used, as shown, by adjusting supply valves 15, 16 or 17 or by-pass valves 18, 19, 20 and 21. The rate of flow of cooling water may be made to vary in accordance with that of the heat carrier fluid by driving the pumps PI and P3 from the same motor or otherwise coordinating the pump drives. Any of the foregoing control means may be effected automatically by a temperature-responsive device fitted in the heat carrier path and actuating the controls through servo-mechanisms.

Doffing and donning device for ring frames comprises a carriage as shown in Fig. 1, a chain movable in a triangle on the carriage, and a unit 1, 2 mounted on the carriage and carrying doffing and donning forks 3, 4, the drive to the chain and carriage being such that the units 1, 2 move vertically relative to the spindles. When a unit begins to ascend, an electromagnet 17 unlocks the doffing fork 3 and allows it to pivot out of the plane of the triangle into a horizontal position. The fork 3 engages a full bobbin and as a result of its vertical motion lifts the bobbin off the spindle. Fork 3 is then returned to its vertical positon by a gude bar 20 and the full bobbin is subsequently removed by a member 27, the full bobbin falling into a magazine. Empty bobbin tubs are placed in a magazine 11 and under the action of an oscillating plate 13 slide into a chute 12. The doffing fork 4 engages a tube in its upward movement, is unlocked by an electromagnet 22 to move into a horizontal position and places the tube on an empty spindle during its downward motion. A guide 24 moves the fork 'back into its vertical position. The thread running from the traveller to the doffed bobbin is gripped against the spindle by a flexible plate and the part thereabove is guided into contact with a knife to be out. A deviator 28 engages the thread running from the traveller and deflect the thread so that the travellers are moved from the front part of the rings.

Abstract: 138,992. Portass, F. W., Fortass, C., and Portass, S. M. Feb. 17, 1919. Kinematograph apparatus. - Relates to apparatus of the type in which the film is fed over a film-carrier. and, after feeding in one direction, the carrier with the film is traversed laterally and the direction of feed reversed to expose another series of pictures, and so on. The present invention refers more particularly to means for effecting the lateral shift and to means for driving the bobbins, other details being described and claimed in Specifications 139,141 and 141,644. A spindle 28 on the carrier 4 has a spindle 27 and two staggered arms 29, 30 mounted on it, the arrangement being such that one of these arms passes through a notch in the carrier to engage the film normally, but, towards the end of the travel of the film in one direction, this arm can pass through the film, allowing the spring-urged arm 25 to move the carrier sideways till the other arm contacts with the film. Means, elsewhere described, are operated at the same time to reverse the direction of feed. The film is pulled off the upper bobbin and fed on to the driven bobbin 37, or vice versa. The drive for the bobbin to be driven comprises an arm 41 which, according to the direction of travel of the film, is in or out of engagement with projections 40 on an extension of the bobbin spindle. A spring-urged member 33 holds the carrier 4 in one position by means of a catch to facilitate threading the film, but is disconnected on pushing to the film gate 35.

In a diversity reception system, the I.F. signals from amplifiers 6, 11 are supplied via variable attenuators 14, 16 respectively and a combining circuit 15 to a detector 17. The outputs of amplifiers 6, 11 are also supplied to a phase comparator 13 whose output controls the local oscillator 5 to bring the two I.F. signals into phase coincidence. Detectors 7, 12 provide A.G.C. for amplifiers 6, 11 respectively and also supply signals to a comparator 18 which supplies the largest of the two inputs to differential amplifiers 19, 20. Amplifiers 19, 20 receive as their other input the outputs of detectors 7, 12 respectively, so that one of the amplifiers provides a zero output and the output of the other is proportional to the difference between the A.G.C. voltages. These outputs control attenuators 14, 16 so that the channel having the strongest signal is not attenuated and the remaining channel is attenuated in accordance with the output of the corresponding differential amplifier.

The tubular chamber of a particle accelerator, e.g. betatron, synchrotron or linear D.C. accelerator, includes a plurality of sections, each comprising a metal tube divided longitudinally into at least two members separated from one another by strips of electrically insulating material to which the members are secured in a vacuum-tight manner. As shown in Fig. 1 for a tube of elliptical cross-section, two metal members 10, 11, e.g. of titanium or constantan, are joined to ceramic or glass strips 12, 13 by U-shaped metal fillets 14-17. The ceramic strips are metallized and brazed to the metal fillets and the metal fillets are welded to the metal members. Strengthening ribs 18 may be pressed into the metal members. As shown in Fig. 3, the metal sections have ceramic end rings 19 and are joined together by metal rings of U-shaped cross-section. The end rings 19 have non-metallized areas to preserve the insulation between the metal members 10, 11 of the sections. The accelerator chamber may be toroidal with each section slightly curved or the curve may be formed in the connections between adjacent straight sections. Two members of a section may be used as beam deflection plates. The members may be heated by passing electric currents through them.
