Title: Improvements in or relating to valve devices for regulating flow of fluid
IPC: G05D16/06
Filed: 1959-11-20
Abstract: 927,363. Valves. E. MURAKAMI. Nov. 20, 1959 [Nov. 24, 1958; Dec. 30, 1958], No.39522/59. Class 135. Upon rotating a knob 14, Fig. 1, to set a pointer 15 at a selected pressure on a scale 16, a pinion 11 rotates a pair of gears which, through screw threads, cause rods 9, 9<SP>1</SP>, Fig. 2, to move in bores H 1 , H 2  and adjust both a bracket 12, Fig. 1, with a micro-switch operating lever 58 pivoted thereon, and a lever 19<SP>1</SP> connected to the free end of a Bourdon tube 3; the latter is open to a pressure apparatus 25 via a passage 2<SP>1</SP>, to which is connected a pressure gauge 23 and a valve V. As the pressure builds up in the Bourdon tube 3 the latter tends to straighten and so turns the lever 19<SP>1</SP> counter-clockwise; at the selected pressure the lever displaces a rod 8 so unseating the movable closure member 5 of the valve V against its spring 6 and connecting the passage 2<SP>1</SP>, by an exhaust duct 31, Fig. 2, and a check valve 36, to a tank 39. Concomitantly, the lever 58, Fig. 1, turns counter-clockwise to close a contact 66 and energize an electromagnet 67, which by a lever 70, produces a further displacement of the closure member 5 so accelerating the opening of the latter. When the pressure in the apparatus 25 falls the Bourdon tube 3 returns to its original position, whereby the lever 58 pivots to open the contact 66 and de-energize the solenoid 67, the lever 19<SP>1</SP> is reset and, together with lever 70, swings away from the rod 8, the spring 6 reseating the closure member 5. The Bourdon tube, valve, solenoid and actuating members are disposed in an hermetically-sealed case 13, Fig. 2, any leakage fluid inside which opens another check valve 45 connected via a tube 40 to the tank 39.

Abstract: 1,196,115. Mechanical switches without quick-action. PLESSEY CO. Ltd. 8 Sept., 1967 [12 Sept., 1966], No. 40735/66. Heading H1N. On rotation of a transparent cap 10, through a shaft 8, gears (7) and a motor 6, a cam 11 thereon sequentially depresses projecting pins 3 of switches mounted in a fixed insulating annular body 2 so that the pins 3 will project from the inner surface 4 thereof. Such operation of a switch causes a resistor to be switched into a bridge circuit and if its value is too large it is switched out and the rest lower valve resistor in sequence is tried when the next pin 3 is operated. For resistances that are too large, a pulse is delivered to a solenoid 9 which attracts a lever 14 hinged on a member 13 on cap 10, so as to bring said lever 14 into the plane of pins 3, and during rotation of cap 10 lever 14 depresses the pins 3 projecting from the inner surface 4 to sequentially release the switches. A wiper contact 16 on cap 10 sweeps long and short contacts 17, 18 and a continuous contact 19, short contacts 18 being connected to a pulse generator and contact 19 to a magnetic tape recorder. When a switch is operated its long contact is connected through circuitry to its short contact and thus to the pulse generator. When a switch is released, the connection between the long contact and pulse generator is broken. As the contacts are wiped, one pulse is recorded for each switch. If a switch is operated and released before the next switch operated, a short pulse is recorded since it is applied via the short contact for a short while. If the switch is not released before the next one is operated, a long pulse is recorded since it is applied via the long contact for a longer while. At the end of a sequence, the solenoid is operated to reset all the switches. The operational positions of the switches may be recorded in binary code.

The capsule 4 is sealed on its front face by means of a removable door 10 while its rear face is rigidly fixed to an operating rod 14. The cavity 6 is sealed beyond the front face of the capsule 4 by means of a shield in the form of a sliding door 20 which can be displaced transversely with respect to the cavity 6 so as to position a cover 28 opposite the removable door 10 of the capsule 4. As is shown in Fig. 3, the door 10 can be locked on to the capsule 4 by right-hand rotation of the latter by means of a bayonet system comprising male elements 10M co-operating with female elements 4F. In addition, the cover 28 can be locked on to a carrier member 26 formed within a recess 24 in the door 20 by left-hand rotation of the capsule 4 when male elements 26M engage female elements 28F. The cover 28 carries on its other face the female elements 28<SP>1</SP>F of a bayonet system, the male elements 4M of which are carried by the capsule 4, locking of this system resulting from right-hand rotation of the capsule 4. The container may be coupled with a hot cell 32 as shown in Fig. 4, the hot cell comprising a shield wall 34 in which is formed a bore 36 centred on a closure mechanism (not shown). A sealed enclosure 38 pierced by an opening 40 is placed within the hot cell 32 with a flange 42 mounted in leak-tight manner in the opening 40 being sealed by means of a door 44. The cover 28 is first detached from the capsule 4 by means of the handle 14 and locked against the member 26 of the recess 24. After displacing the door 20 to bring an opening 22 therein opposite the cavity 6, the capsule 4 is pushed through the bore 36 of the hot-cell wall 34 by means of the handle 14 until the capsule 4 is in contact with the flange 42 and the capsule door 10 is in contact with the door 44 of the enclosure 38. The capsule 4 is then locked in position against the flange 42 while the door 10 is locked at the same time on the door 44 by means of the handle 14. By making use of a manipulator 46, it then becomes possible to open the capsule 4 by simultaneously releasing the doors 10, 44 from the flange 42 and the capsule 4 in order to carry out loading or unloading of this latter.

A method of synchronizing precision clocks 11, 12 by determining the time difference between the clocks which are spaced a large distance apart comprises transmitting reference pulses over existing wide band transmission and reception systems. A television studio 20 comprising a source of synchronization pulses is linked to a television transmitter 21 which transmits pulses from the television signal. At the location of each clock 11, 12 is a device 41, 42 which selects a reference pulse from the television signal, the signal to the device 42 being received from a transmitter 22 linked to an end station 31 via a retransmission line 3 and a further end station 32. Each device 41, 42 comprises a television receiver 4 the output of which is fed to a circuit 5 which selects a line synchronization pulse from an interval of one television signal frame. The output of each circuit 5 and the associated clock 11 or 12 are connected to an associated counter 6. If the time pulses of the clocks 11, 12 arrive at the inputs of their respective counters at the moments t 11 , t 12  and a synchronization pulse arrives at the inputs of the respective counters at the moments t 41 , t 42 , then the following equations are satisfied; T 41  = A + t 11  T 42  = B + t 12  and #t = A-B + t L  where #t = t 12  -t 11 , t L  = t 42  -t 41 , A and B are the time differences between the time pulses of the clocks 11 and 12 respectively and the arriving synchronization pulses from the studio 20. Since A, B are measured by the counters and t 41 , t 42  can either be measured or calculated in advance from the length of the transmission routes and the velocity of electromagnetic waves, the required time difference #t between the clocks can be calculated.
