Title: Improvements relating to selector valves for nuclear reactors
Inventor: DEAN JOHN RAYMOND
IPC: F16K11/074
Filed: 1957-11-29
Abstract: 900,308. Valves. REYROLLE & CO. Ltd., A. Nov. 28, 1958 [Nov. 29, 1957], No. 37311/57. Class 135. A selector valve for controlling the flow of reactor gas through the gas passages of a gascooled nuclear reactor comprises a valve body affording a row of spaced inlet ports and an associated row of spaced outlet ports all leading into a common outlet passage, a selector member formed with a sealing surface which mates with the surface of the valve body and formed with a bridging conduit, for example as surface recess, means for moving the selector member relatively to the valve body into any one of a number of stations, in each of which stations the selector member covers a selected inlet port and an associated outlet port and places the two ports in communication with one another via the bridging conduit, the sealing surface then extending in sealing contact with the valve body completely around each or both of the two ports to seal them off from the surrounding region and means for closing the remainder of the outlet ports. The valve comprises an outer circular row of inlet ports 31, Figs. 2 and 3, in a bed 32 and an inner circular row of associated outlet ports 33 leading to a common outlet 35. A carrier 36 is mounted on a spindle 37 and is rotated in step-by-step manner by a motor 45 through coupling 42, 43, 43<SP>1</SP>. A yoke member 50 fixed to the carrier 36 has a depending fork member 51 which engages a valve member 52 which is thereby moved in sliding contact with the upper metal surface of the bed 32 so that its recess 55 successively connects pairs of inlet and outlet ports 31, 33, respectively. The other outlet ports 33 are sealed by sealing member 58 carried by a ring 56 fixed to the carrier 36. The valve member 52 and sealing members 58 may be made of graphite or ceramic material. The inlet ports 31, other than the one in use, lead directly to the interior of the valve housing 47 so that the resulting gas pressure therein biases the valve member 52 against its seat. In a modification, Fig. 4 (not shown), the valve member is movable to N stations, there being N - 1 inlet ports and N/2 outlet ports. The valve member has a T-shaped recess so that one outlet port is successively connected to each of two adjacent inlet ports. A selector valve, as described above, is located at 21, Fig. 1, in each of the stand-pipes 22 extending from the pressure vessel 11 of a nuclear reactor so that the pipes 20 leading from fuel channels 12 may be successively connected to a pipe 24 leading to the fission products detector 25.

[Also in Division F2] A composite compressible roller, for use in a machine handling sheets of polystyrene ceiling or wall tiles, comprises a cylinder 3 of foamed polyurethane surrounding and fast with an internal hollow steel shaft 2 which is supported on and rotatable with a coaxial solid steel centre shaft 1, the composite roller having a diameter which is approximately three times the diameter of the internal hollow shaft 2. The foamed polyurethane has a density of 40 kilograms per cubic metre, a degree of compression equal to 25% of the uncompressed thickness of the material under an applied pressure of 18À3 pounds per square inch, and a tensile strength of 25 pounds per square inch. The density may be such that an applied pressure in the range of 15 to 30 pounds per square inch will achieve a compressibility of 25%. Power driven pairs of such rollers 10, 11 are used in a machine for feeding sheets of foamed polystyrene via guide tracks 13, 14 to and from a cutting and/or marking cylinder 12 therebetween, the polystyrene sheets being individually fed from a stack 16 to the rollers 10 by a further similar composite roller 15 provided at its periphery along all or a portion of its cylindrical length with a segment 18 of foamed polyurethane, the segment 18 engaging the underneath surface of the lowermost sheet of the stock 16 and removing it therefrom to a guide 17 for collection by the rollers 10 for feeding to the cutting and marking cylinder 12. The diameter and speed of the rollers 10, 11 is the same, but the centre spacing of outlet rollers 11 is greater than that of the inlet rollers 10 and both centre spacings are less than the diameter of the rollers whereby the difference in effective roller radius, i.e. nip, contacting the polystyrene tile sheets provides a greater effective surface speed at the rollers 11 relative to the rollers 10 whereby the tile sheets are maintained under tension to avoid creasing thereof.
