Abstract: 1491204 Thermal insulation NUCLEAR POWER GROUP Ltd 31 Oct 1974 [31 Oct 1973] 50718/73 Heading F2X A metallic wall for a primary vessel of a liquid metal cooled nuclear reactor, is clad with thermal insulation comprising a layer 3 of insulating blocks 4 spaced from the wall 1, the blocks being spaced apart and each block being individually and rigidly secured to the wall 1 by means of a central stud bolt 5 and a nut 6. In the Fig. 2 embodiment, the spaces between the blocks 4 are closed to convectional flow of liquid by resilient closure members 7, 8 and a flexible membrane covering 9 is spaced from the layer 3, openings (not shown) in the covering 9 allowing liquid from the reactor vessel to penetrate between the covering 9 and the layer 3, thereby balancing the pressure across the covering. The openings may comprise small perforations in the lower regions of the covering 9. The blocks 4 are rebated at their rear faces and grooved on their side faces to house the resilient closure members 7, 8 respectively. The closure members are formed from high temperature alloy steel strip, the rear members 7 being of C cross-section and the side members 8 of X cross-section. An alternative form of closure member 7 comprises a sintered stainless steel openwork frame which is compressed into sealing engagement with sealing grooves in the rear faces of the blocks 4 on assembly (Fig. 3, not shown). The covering 9 is of stainless steel sheet, ribbed in orthogonal pattern to give flexibility for the accommodation of thermal stresses, and secured by extended block retaining stud bolts 5a and nuts 6a. In order to reduce complex stressing of the covering 9, the intersections of the ribs may be cut away in which case the perforations in the lower regions of the covering may be omitted. Thermal expansion of the blocks 4 is accommodated by closure of the block interspaces. In the Fig. 4 embodiment, the membrane covering comprises a plurality of discrete sheets 21 each secured by the bolt 5b of an associated block 4. The sheets 21 overlap adjoining blocks 4 at their edges and carry closure members 22 in the form of an elongated U cross-section with slits 25 for the relief of thermal stresses and a lip 23 housed in a rebate (24) (Fig. 5, not shown) of an adjoining block 4. The insulating blocks 4 may be of solid stainless steel, of cellular or porous material, or of hollow shells containing ceramic material or an inert gas.

Abstract: 1449235 Shelling beans BUEHLER AG Gebr 31 Oct 1973 [1 Nov 1972] 50729/73 Heading A2Q Beans, especially whole soya beans, are treated to reduce the bitter taste and facilitate shelling by submitting them in a fluidized bed to rapid heating so as to vaporise moisture within the beans thereby rupturing the shells. In a preferred embodiment, the beans are fed through inlet 10 into fluidized bed apparatus 1 which includes two air supplies 16 and 19 each supplied with its own heater and air pulsator. The treated beans are then fed to rotary impact sheller 2 where they are thrown outwards on to baffle ring 42, thereby loosening the shells from the kernels. The resulting mixture of shells and kernels is separated in fluidized bed separator 3 wherein air is drawn through by suction. Some of the air may be heated. The shelled kernels are collected at 52.

Abstract: 1535103 Distillation of metals ENERGIAGAZDALKODASI INTEZET 6 Dec 1976 50787/76 Heading C7D [Also in Division H5] Metals are recovered from ores or alloys by a distillation process which involves interacting a mixture of comminuted metal ore or alloy with oxygen or air together with a plasma beam formed from a non-combustible or inert natural gas, to evaporate the metal(s) to vapour(s) and pass the metallic vapours through a series of cooling chambers whose walls are cooled to the melting points of the individual metals, thereby precipitating each metal separately. The natural gas preferably used contains mainly CO 2 , and the only purification necessary is to remove the water vapour. The plasma generator may be of a commercially-known type.

Abstract: 1439395 Valves SIEMENS AG 5 Nov 1973 [6 Nov 1972] 51335/73 Heading F2V [Also in Divisions Gl H2 and F1] Three hydraulic valves 23, 24, 25 are connected in parallel in an oil circuit H01, each of the valves being controlled by a respective pair of electromagnetic valves 20a, 20b, 21a, 21b, 22a, 22b. Each of the control valves, in the "on" condition sends auxiliary control oil St0 through a non-return valve 66 to the respective spring-loaded valve 23, 24, 25 so that the return flow path RF for the oil from H01 is shut off. When either one of the two control valves, associated with an hydraulic valve, closes, e.g. 20a or 20b the control oil pressure of the other control valve acts on the non-return valve 66 to shut off the one valve whereby the associated hydraulic valve remains closed. Only if both the electromagnetic control valves are deenergized is the corresponding hydraulic valve changed over by oil pressure and spring force so as to connect oil circuit H01 with the return path RF. The control valves are energized by an electric circuit arrangement for detecting overspeeding of a turbine (see Division G1).
