Title: Improvements in devices for selective electric protection
IPC: H02H7/26
Filed: 1945-12-12
Abstract: 610,837. Protective cut-out systems. COMPAGNIE ELECTRO-MECANIQUE. Dec. 12, 1945, No. 33701. Convention date, June 30, 1943. [Class 38 (v)] In a three-phase protective arrangement wherein only the switch in a faulty phase is actuated, the rectified alternating voltages between each phase and earth (represented in the Figures by batteries e1 ... e3) are connected in series with rectifiers R1 .. : R3, in parallel with a potentiometer PA partly shunted by a condenser CA. If one phase fails, the others feed it in the reverse direction, thereby creating a voltage across the appropriate rectifier, this voltage being used to operate the release mechanism. If two phases fail, voltages appear across the two rectifiers, and if all three fail, the condenser CA feeds all three, thereby setting up a voltage across each rectifier. In Fig. 2, a point ED on the potentiometer PA is connected by rectifiers R<1>1 ... R<1>3 to the grids of gas tubes L1 ... L3 controlling the release valves V1 ... V3. A battery Eo provides a bias against operation of the tubes L1 ... L3 and is normally assisted by the potentiometer volt-drop eD. If a fault occurs, say in phase 3, voltage e3 drops and current from the other sources e1, e2 flows from ED via R<1>3 to the grid of tube L3, so avoiding the bias eD, but the bias eo is only wiped out, to produce tripping, on internal fault, when a directional control impulse is received via the transformer T.

Title: New or improved method of or means for preventing freezing of hydraulically-operated valves for controlling the flow of water
IPC: F16K31/122
Filed: 1946-11-18
Abstract: 618,991. Preventing freezing of valves. BLAKEBOROUGH, R. A., and KLOUMAN, F. A. Nov. 18, 1946, No. 34055. [Class 135] Freezing-up of a hydraulically-actuated valve is prevented by causing a stream of water from the main controlled by the valve to flow in close contact with the inner surface of the wall of the actuating cylinder. As shown, water from the main flows into a chamber b in the bottom of the actuating cylinder, past grooves c' formed in projections supporting the annular plate d which defines the chamber b, through peripheral slots d<1> in plate d, and then upwards against the lining e of the cylinder. This stream of water exhausts into the hollow piston g<1> through a gap m, then through ports f<2> into the hollow stem connecting the piston with the valve, and out past a non-return disc valvo p. When the valve v is located in the throat of a venturi tube, the pressure differential produced ensures the continuence of the flow, but the required differential may be obtained by using Pitot tubes. A flexible diaphragm, seating against the central aperture in plate d, acts as a non-return valve to permit the exhaust of water from under the piston when the valve is being closed. To prevent freezing of the water above the piston when the latter is in its raised, valve open, position, a valve s connected to the tail rod t of the piston is opened to drain the upper end of the cylinder as the piston rises. Air to permit of this discharge is admitted through a valve u.

Title: Digital synchronization circuit
IPC: H04L7/033
Filed: 1960-10-05
Abstract: 885,139. Automatic phase control systems. COLLINS RADIO CO. Oct. 5, 1960 [Dec. 7, 1959], No. 34176/60. Class 40(5). A local signal # d  is synchronized with a received signal f in . The local signal f d  is obtained by dividing at 28 the output of a clock pulse generator 26; divider output # d  = # in . When wave # in  is received switch 15 closes, until f in  ceases, and the wave f in  is applied to a one shot device 11, e.g. a multivibrator, triggered by a positive going pulse. f in  is also applied to an "and" gate 12, and to its other input is applied # d . "And" gates 13, 14 are connected to the one-shot 11, and also to the output of "and" gate 12, the input to gate 14 being inverted by circuit 20. An "or" gate 21 has 3 inputs, 22 receiving clock pulses, 23 the output of "and" gate 13, and 24 the output of inverter 16, which differentiates and inverts the output of gate 14. The output of gate- 21 is applied to the frequency divider 28. Assuming signal f in , A, Fig. 2, lags the local signal f d , B, the output of gate 12, C, is applied to gate 13, F, with output E of one shot 11, and the output of the gate is applied to the "or" gate with clock pulses I. Each one shot pulse blocks one or more clock pulses. The divider output f d , K is delayed by one clock pulse period for each blocked clock pulse. Thus the output wave f d  lags by a time increment of 360‹/R phase shift for each deleted clock pulse, where R is the division ratio of divider 28. Where f d  lags f in  a similar sequence takes place. Gate 13 gives no output because there is no coincidence between positive input pulses. Owing to inversion of the input to gate 14 an output is produced thereupon, which is then differentiated and inverted 16 (H, Fig: 3). The "or" gate 21 pauses only positive pulses. These are applied to divider 28 (J, Fig. 3). Each added pulse advances the divider output phase in a leading direction by 360‹/R. Specification 863,593 is referred to.

Void [Published under Sect. 91 of the Acts]. 38 (ii).] In means for converting polyphase currents into single phase currents of higher frequency, a pair of rectifying devices III, Fig. 1, are associated with a polyphase supply transformer comprising primary windings I and secondary windings II, the single phase load IV being connected between the cathodes of the devices III and also to the star points a, b of the transformer secondaries. Thus current flowing alternately from the windings a, b through the devices III passes in opposite directions through the load IV. In an alternative arrangement, a similar transformer system is associated in the manner shown in Fig. 2 with a single cathode rectifying device, the cathode of which is connected to the mid-point of the primary winding of a single phase transformer feeding the load IV, current from the windings a, b passing alternately through opposite halves of the output transformer primary. Other arrangements of windings for supply transformers for different numbers of phases on the input side are diagrammatically illustrated in Figs. 3 to 6 (not shown). The Specification suggests that single phase current of the same frequency as the polyphase current can be obtained, and also that the wave form of the output can be modified by the use of " chokes, screen chains, or grid potentials."
