Title: Pilot operated fluid pressure regulator
IPC: G05D16/16
Filed: 1970-06-22
Abstract: 1,263,671. Valves. WILKERSON CORP. 22 June, 1970 [23 June, 1969], No. 30176/70. Heading F2V. [Also in Division G3] In a fluid pressure regulator, which is designed to maintain the outlet pressure constant regardless of the selected valve of this pressure control of flow between an inlet 26 and an outlet 28 is effected by means of a main valve member 12 which is biased towards its seat 30 by a spring 40 and which has operatively associated therewith a pilot control arrangement 10. The control arrangement comprises an upper piston 86 subjected to a downwardly directed bias of Belville washers 136, a lower piston 58, a pilot chamber 14 defined by the two pistons, and a three-part pilot control valve 82, 84, 76; the first part 82 being in the form of a pin along which the top piston 86 can move freely and which can be moved inwardly or outwardly relative to the valve housing 16, by means of a handle 162, the second part 84 being formed integrally with the upper piston 86 and the third part 76 being disposed within the hollow stem of the valve member 12. In the state of the regulator shown, no flow takes place between the inlet 26 and the outlet 28. Upon a demand being created at the outlet, the pressure in the latter will fall. In consequence, lower piston 58 moves downwardly imparting a similarly directed motion to the main valve member 12 by virtue of the engagement of piston land 102 and valve stem 50. Such movement of the lower piston is followed by lowering of the upper piston and hence in the movement of pilot valve part 76 away from pilot part 82 with the result that communication is established between the pilot chamber 14 and the inlet 26 by way of passage 26, 60, 72, 88, 146 and 142. The pressure in chamber 14 increases and so the upper piston 86 moves in opposition to the downward bias simultaneously closing the pilot valve 82, 84, 76, whilst the lower piston which is subjected on its underside to the outlet pressure and which controls valve 12, attains a position corresponding to the desired pressure at the outlet, such pressure being predetermined by the equilibrium pressure in pilot chamber 14 which in turn is pre-set in consequence of the setting of pin 82. Upon the pressure in the output line rising, the lower and upper pistons move upwardly. In consequence of such movement, main valve member 12 moves towards its seat, and pilot valve parts 84 and 76 become separated permitting partial exhaust to atmosphere of the pilot chamber 14 via passage 142, 146, 150 and 140, a lowering of the pilot chamber pressure resulting in the upper piston returning to its equilibrium position whereat the pilot valve is closed and in the lower piston attaining a new equilibrium position. Sudden surges in the outlet 26 may be exhausted directly to atmosphere by separation of land 102 of lower piston 58 and the topmost part 104 of main valve member stem 50. In a modification (Fig. 7, not shown), the regulator is separated into two parts interconnected by a hose but functions identically as above.

Abstract: 1,173,345. Monitoring reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 21 June, 1968 [30 June, 1967], No. 30191/67. Heading G6C. Burst cartridge detection apparatus for a liquid metal cooled reactor comprises a stack of four layers 11 of lead separated by steel shielding layers 12. Each layer 11 has a circular array of sample chambers 18a . . . 18h, a first array of neutron BF 3  counters 13a . . . 13h and a second array of neutron BF 3  counters 14a . . . 14h. Each sample chamber 18 is connected to an individual one of thirty two sample ducts 21 extending through a channel 22 in the centre of the stack. A branch 19 leads from each duct 21 to a chamber 18 and an outlet branch 20 from each chamber leads to a common return duct 23. Each BF 3  counter is embedded in a polythene cylinder 15 and shielded by a cadmium sheath 16, the chambers 18 of a given layer 11 being shielded from each other by radially-extending polythene members 24. The counters of the arrays 13 are connected together to form eight vertical groups each of four counters, e.g. the four counters 13a form one such group. Also, alternate counters of the array 14 of each layer 11 are connected together to form two horizontal groups. The eight vertical and eight horizontal groups are continuously scanned, the presence of neutrons in one of the chambers 18 being detected by the three adjacent counters. For example, neutrons in chamber 18g are detected by counters 14f, 14g and 13g. The counters 14f, 14g determine the particular layer 11 and the counter 13g the position in that layer and thus chamber 18g is located uniquely.

Switches that can be stacked as shown in Fig. 2 comprise pairs of rotary arms SW1, SW2 that can engage fixed contacts F3, F4 or the arms of the adjacent switch. The arms are rotated by mechanism having lost motion which gives a slow motion to the arms in their extreme positions. As shown in Fig. 3, the arms are fixed to shafts S1, S2 to which are fixed links CR1, CR2 having slotted ends engaging a pin LP carried by a link L which can be rotated by a crank CR on a shaft CS which passes through the switch casing. The other end of each shaft CS carries two arms Al, D1 as shown in Fig. 1, which can be rotated in a predetermined sequence by means of a chain CH having short and long links the latter carrying projecting pins R. No rotation of a shaft CS takes place while the chain is moving and short links are passing under the corresponding arm A1. When a pin R engages the arm D1 the latter is rotated through a quarter revolution, a half revolution being completed by a cross-pin of the chain engaging the arm A1. The chain may be motor driven and may be replaced by a belt having holes or other similar operator.
