Title: Improvements in or relating to Nuclear Reactor Pressure Vessels having Thermal Insulation.
Inventor: ROBSON ARTHUR GRAY
IPC: B01J3/00
Filed: 1966-06-20
Abstract: 1,194,333. Thermally insulating laminates. NUCLEAR POWER GROUP Ltd. 15 June, 1967 [20 June, 1966], No. 27434/66. Heading B5N. [Also in Division G6] Thermal insulation for pressure vessels for nuclear reactors, comprises sheets separated by spacer members (which may be integral parts of the sheets) to form interspaces, at least some of the sheets and/or spacer members being of a non-metallic material such as compressed asbestos so that when the insulation is compressed on installation, fluid is unable to pass freely between the sheets and spacer members from one interspace to another. The spacer members may occupy the whole space between the sheets, in which case they are fibrous so as to divide that space into a large number of interspaces. The sheets and spacer members are secured to one another and to the pressure vessel by studs in the latter carrying nuts and, if desired, the nuts may act through cover-plates or strips on the outside of the insulation, and flexible metal plates may be interposed between the cover plates and the insulation or between layers of the insulation. The sheets may be of stainless steel, asbestos (which may be metallized) or sandwiches of the two materials, and the spacer members may be asbestos, ceramic material or, where the sheets are non-metallic, stainless steel. The spacer members may form, a grid and may be of mesh or netting, or may be in the form of bricks or of sheets of uncompressed asbestos, in which ease, ribbed metallic sheets may be used. In one form, the sheets are formed on one or both sides with integral spacing projections. The interspaces may be filled with loose asbestos.

Title: Improvements in or relating to refrigeration apparatus
IPC: F25B41/06
Filed: 1963-07-11
Abstract: 1,088,463. Refrigerating. W. G. NOLCKEN. July 13, 1964 [July 11, 1963], No. 27478/63. Heading F4H. [Also in Division F2] In a refrigeration system of the compression-type having a capillary expansion tube, valve means are provided for regulating the flow of refrigerant to said tube. As shown, the valve means comprises a chamber 1 which receives refrigerant from the condenser (not shown) through a tube 2 and contains a hollow vessel 3. The lower part of a capillary tube 5 extends through the roof of chamber 1 and into vessel 3, the arrangement being such that when the level of liquid refrigerant in chamber 1 is low the vessel 3 rises and closes the bottom of tube 5 as shown, and when the liquid level rises refrigerant enters vessel 3 through apertures 4, causing the vessel to sink and open tube 5. In a modification of this arrangement (Figs. 3 and 4, not shown) the lower end of tube 5 is closed by a plug and an orifice is provided in the wall of the tube above the plug, this orifice being opened or closed by a cylindrical sleeve secured to the bottom of vessel 3. In the modification of Fig. 6 (not shown), a second capillary tube (500) is provided which when the compressor is switched off and the liquid falls below a predetermined level (c) allows refrigerant vapour to pass to the evaporator to cause pressure equalization in the system. Alternatively the second capillary may be omitted and an orifice provided in the wall of the other tube (Fig. 5, not shown). In further modifications either a capillary tube communicating with the bottom of chamber 1 or an orifice in the lower part of vessel 3 is provided to lower the liquid level in the chamber and cause vessel 3 to sink during " off" periods, thereby permitting pressure equalization via tube 5 (Figs. 5 and 7, not shown).

Abstract: 712,768. Speed governors. C.A.V., Ltd. Nov. 26, 1952 [Nov. 28, 1951], No. 27888/51. Class 57 In a spill-type reciprocating liquid-fuel injection pump a in which the amount of spill is controlled by a slidable rack bar b actuated by a speed-governor, the speed-responsive masses e and the bar b are connected by a lever mechanism formed by a pair of articulated and spring-controlled parts normally in alignment and adapted to be deflected laterally relative to each other against the action of the spring, the articulated lever being carried by a manually operable lever v. The masses e are driven by the pump shaft h and connected by bell crank levers i to an axially slidable spindle connected to the bar b by a lever mechanism consisting of a hollow cylinder k pivoted to the bar b and housing a piston q pressed by a spring p on to a collar o of a rod n extending through a transverse slot r in the cylinder k and secured to a forked member m pivotally connected both to the spindle j and, by a pin s, to a forked supporting lever t carried by a pin u and having at one end thereof the manually-operable adjusting lever v. The endwise movement of the bar b is limited by contact of a collar c thereon with an adjustable stop d and the adjacent part of the pump body and when the bar is intermediate these limits the connection between it and the spindle j acts as a rigid lever to transmit movements due to the governor, and movement of the lever v alters the position of the pivot pin s. If the bar is against one of its limit stops, however, further movement of the lever v is catered for by relative movement between the rod n and the cylinder k, the head o tilting in the cylinder and moving the piston q by compressing the spring p.
