Patent GB-675750-A (GB)
Abstract: 675,750. Electrostatic voltmeters. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 8, 1951 [Feb. 9, 1950], No. 3115/51. Class 37. An electrostatic voltmeter comprises a fixed member 3 and a movable member 4 between which the voltage to be measured is applied, and a variable force is applied to deflect the member 4 until it snaps away from the member 3, the magnitude of the variable force then being equal to the electrostatic force and a measure of the applied voltage. In Fig. 1, the variable force is due to gravity and is developed by tilting the whole instrument, the angle at which the member 4 snaps away from 3 being shown by the reading of a plumb line 9 on scale 10. For small voltages, the snap-action is facilitated by a further electrode to one side of member 3 and at the same potential as the filament 4, Figs. 3 and 4 (not shown). In Fig. 7, the filament 35 co-operates with an electrode 33 shielded by electrode 34, and is viewed through a lens 42; the adjustable force is again produced by tilting the case, the extent of tilt being indicated by the co-operation of an index 47 on the case and a scale carried by a pivoted mass 43. In Fig. 10, two filaments 52 are supported from a member 55 and carry a small frame 54 which co-operates with a fixed member 50 and a shielding electrode 56. The extent of tilt is indicated by a plumb-bob 59. In Fig. 13, the filament is in the form of an arc 64, a similarly arced shielding electrode 66 being provided, while the fixed member 62 extends from the wall of the case; the adjustable force is due to gravity and the deflection of the case is indicated by a bubble 69, Fig. 12, in a curved tube 67. In Fig. 15, the adjustable force is electromagnetic. The movable member 89 is in the form of an arc and carries an adjustable current from source 95 so that a permanent magnet 93 produces a deflecting force proportional to the current. The voltage between 89 and 87 is indicated by the setting of resistance 96 sufficient to deflect the arc 89. In Fig. 17, the adjustable force is due to the torsion of a filament 106. A number of rods 104 are suspended on a torsional filament 106 in co-operation with fixed electrodes 101, and the torsion head 110 is rotated until the torsion is just sufficient to overcome the electrostatic attraction between the rods 104 and the electrode 101. In Fig. 19 the adjustable force is magnetic; the movable electrode 113 is torsionally suspended and carries a magnetic member 124; a magnet 125 on a disc 126 is adjusted by rotating the disc until the magnetic force on 124 just overcomes the electrostatic attraction between 113 and fixed wire electrodes 118, 119.

Patent GB-2036258-A (GB)
Title: Flow control valve
IPC: F16K31/122
Filed: 1978-12-01
Abstract: In a slow-opening valve a pilot valve is opened to allow upstream pressure to move an actuating piston upwards against a stop. This movement compresses a biassing spring and cracks open the closure member. Thereafter the compressed spring slowly opens the closure member against the decreasing pressure differential thereacross and the reducing force generated by the flow acting on the cup-shaped formation on the closure member. A fall in downstream pressure causes the closure member to move to a throttling position. <IMAGE>

Patent GB-2077368-A (GB)
Title: Packing assembly
IPC: F16J15/32
Filed: 1980-06-05
Abstract: A seal member 16 is disposed in an annular groove 12 in a piston 10 and has lips 17 which seal respectively against a base wall of the groove 12 and the side wall of a cylinder (not shown) when the seal member 16 is subjected to fluid pressure from an active end of the cylinder.
