Abstract: 1,054,933. Reactors. GESELLSCHAFT FUR KERNFORSCHUNG m.b.H. Sept. 16, 1963 [Sept. 15, 1962 (2); wept. 20, 1962], No. 36424/63. Heading G6C. The fuel in a nuclear reactor is so arranged that its cross-section as presented to the coolant flow diminishes in the direction of the flow and the cross-section of the fuel channel also diminishes in the same direction. Thus, the coolant velocity (and consequently the heat transfer co-efficient) is a minimum where the coolant is coldest, and at a maximum where the coolant is hottest. Fig. 4 shows a spherical core for a reactor, in which coolant enters through the triangular bases of the frustro-conical fuel channels, and passes out from the centre upwards through an axial funnel. Each coolant channel houses an assembly of metal coated spherical fuel elements as illustrated in Fig. 1. An alternative fuel assembly (Fig. 3, not shown) comprises a bundle of parallel fuel rods, the bundle being of trapezoidal cross-section; these are assembled in similar shaped fuel channels forming cylindrical sections. In all embodiments, the object is to maintain all fuel element surfaces at the same temperature, regardless of the relative positions in the coolant flow. Beryllium oxide may be added to the ceramic fuel. A steam cooled fast breeder reactor (Fig. 5, not shown) utilizes spherical fuel elements in a core of the type shown in Fig. 4, above which is mounted an evaporator, superheater, primary coolant circulator, and steam turbines to drive them, in a single pressure vessel. In an emergency, the reactor core may be flooded with condensate from the evaporator immediately above the core. In the case of a thermal reactor, the coolant channel may contain solid moderator, or a combined moderator and coolant may be made.

Abstract: 1,227,465. Pilot-operated gas valve. ROBERTSHAW CONTROLS CO. Oct. 11, 1968 [Oct.13, 1967], No.48388/68. Heading G3P. With temperature responsive valve 42 open, gas from inlet 18 can pass via 40-46 to chamber 48 to depress diaphragm 70 to unseat valve 66 thereby opening by-pass line 56, 58, 72, 54. The pressure in the by-pass line is controlled at a preset level determined by pressure regulator 74-86 and is communicated at 60 to chamber 34 to allow opening of main valve 26. Upon closure of valve 42, the pressure in chamber 48 falls, due to escape of gas via 50, 52, 54, and valve 66 seats thereby causing the pressure in chamber 34 to approach inlet pressure and close valve 26. In the modification of Fig.2 (not shown), the temperature responsive valve (42) admits gas to chamber (114) when open to depress diaphragm (104) thereby subjecting the diaphragm (94) of pressure regulating valve (90) to a load via spring (100). Valve (90) then controls pressure in a by-pass line as above to position the main valve (26). Gas escapes from chamber (114) via (116, 118) when valve (42) closes thereby allowing spring (96) to close valve (90) to cause closure of valve (26).
