Title: Improvements relating to nuclear reactors
Inventor: CAMPION PETER
IPC: G21C15/28
Filed: 1965-11-16
Abstract: 1,125,810. Cooling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 7 Nov., 1966 [16 Nov., 1965; 15 Feb., 1966], Nos. 48719/65 and 6675/66. Heading G6C. A carbon dioxide-cooled, graphite-moderated reactor has incorporated in the coolant circuit a catalyst to promote in the presence of excess carbon dioxide the reaction between carbon monoxide and hydrogen to produce methane. The coolant contains methane in order to inhibit the graphite-carbon dioxide reaction. Radiolysis of the coolant still occurs however, three main products being carbon monoxide, water and hydrogen. The major methane-producing reactions promoted by a catalyst are In the presence of a suitable catalyst the water formed will react with further quantities of carbon monoxide in accordance with the equation: The hydrogen so formed reacts with more carbon monoxide to produce methane. Accordingly, the methanation catalyst may be mixed with or preceded by a catalyst, e.g. zinc/ copper or chromium-promoted iron, to promote the above carbon monoxide-water reaction, or a methanation catalyst may be selected which will also promote the above carbon monoxidewater reaction. A suitable methanation catalyst is nickel on a support such as chromia or kieselguhr. The catalyst or catalysts are conveniently installed at the outlet of the heat exchangers for the r actor coolant. Since nickel catalysts are poisoned by sulphur it may be desirable to desulphurize the coolant just prior to the catalyst bed or beds. Zinc oxide may be used as an absorbent for this purpose. Instead of adding methane to the coolant to inhibit the graphitecarbon dioxide reaction, water may be added. The water is converted to methane by passing through the catalyst or catalysts with reactor coolant which contains carbon monoxide. Further the catalysts may be used to control the carbon monoxide content of the coolant by providing a quantitative oxygen feed into the coolant system prior to a catalyst bed.

IPC: F02K1/76
Filed: 1967-11-07
Abstract: 1,246,616. Control apparatus for jet deflectors. ROLLS-ROYCE Ltd. 30 Jan., 1969 [7 Nov., 1967], No. 50554/67. Heading B7G. [Also in Division F1] A jet propulsion power plant for aircraft comprises a deflector member which is movable so as to deflect the jet stream, also a fuel control system having means to vary the flow of fuel between high and low values, there being auxiliary means connected to the deflector member so as to restrict the fuel flow to a low value when the deflector member is in a position between its terminal positions. The power plant shown comprises a pair of thrust reverser members 12 which are movable by actuators 15 between an inoperative position 13 in which they are clear of the jet stream J, and an operative position 14 in which they deflect the jet stream with a forward component for reverse thrust. A fuel supply system comprises a valve member 24 which is movable by the throttle control 19 between a minimum flow position 25 and a maximum flow position 26, the fuel passing through an auxiliary control 30 to the fuel burners 22B. The auxiliary control 30 comprises a spool valve 31 mounted for axial movement in a cylinder 31A the spool being connected through a lost motion device 43 to the reverser member 12. When the members 12 are in the inoperative position 13, the groove 33 of the spool is aligned with the fuel ports 32 so that the fuel flow is as determined by the throttle valve 24. Similarly when the reverser members are in the operative portion 14, the groove 34 of the spool is aligned with the fuel ports 32 and the fuel flow is again as determined by the throttle valve 24. But when the reverser members are in an intermediate position, the enlarged portion 35 of the spool is aligned with the fuel ports 32 so that whatever the position of the throttle 24 the fuel flow is limited by the enlargement 35. A locking means 38 is provided which when the enlarged portion of the spool is aligned with the fuel ports 32, is urged by spring means into the recessed portion 37 of the spool. The locking member 38 is disengaged from the recess 37 by means of a flange member on the throttle valve when the throttle is moved to a low setting 25. The lever 18 for controlling the thrust reverser is mounted on the throttle lever 19 and can only be moved when the throttle lever is in a low power position in which a spigot 47 on the lever 18 may engage a recess 48 in the throttle gate. The object of the invention is to ensure that should the thrust reverser be moved as a result of some failure to an intermediate position, the fuel flow is automatically reduced from a high value to a low value.

Openings in the jacket correspond to a region 23 between the limbs 10, 11 of the U- tubes and this region is lined with walls 25, 26, 27 which are joined to the jacket and define a central duct 28 for the water. At its lower end the duct 28 is constricted by inclined plates 30, 31 to funnel water via openings 34, 35 in the plates 25, 26 on to the centre of the U-tube nest and the relative size of the openings 34, 35 is arranged to direct more water on to the hot limb 10 of the tube nest. Three apertured rings 36, 37 (movable) and 38 (fixed) can be adjusted to control water flow in down space 18. Only two rings could be used if necessary of a different form of throttle means could be provided.

Abstract: 1,138,060. Axial-flow fans; cooling engine cylinders. DIESEL MOTORENWERK SCHÍNEBECK VEB. Nov.18, 1966, No. 51866/66. Headings F1B and F1C. In a cooling fan for an I. C. engine, the rotor 10 is driven through a fluid coupling 9 discharging fluid, e.g. oil, through a bore 14 into a collecting chamber 8 which in turn delivers the fluid through ducts 16, 17 into a steering gear-box or a crankshaft housing 1. The duct 16 extends through a stationary aerofoil 15, and the duct 17 extends through a support 2 for the fan. Air can pass from the housing 1 to the chamber 8 through a passage in the support 2, a bore in a second stationary aerofoil, an arcuate passage 19 and a passage 20. A regulator 23 controls the fluidflow through the coupling, and thus the torque transmitted thereby, in accordance with engine temperature. Leaking fluid from the regulator passes through a passage 24 and into the housing 1 via the duct 17 or via the bore in the second stationary aerofoil. The rotor casing 4, the support 2 and the housing 1, or only two of these parts, may be moulded as one piece.
