Abstract: 673,988. Capacitor measurements. SMITH & SONS (ENGLAND), Ltd., S. Aug. 18, 1950 [Aug. 31, 1949], No. 22597/49. Class 37. In a device for measuring the liquid contents of a tank using a condenser the dielectric of of which is formed partly by the liquid, the weight of the liquid, corrected for variations in density due, e.g. to temperature variations, is indicated. Liquid is pumped continuously by a pump 22 from the tank 18, Fig. 2, containing the liquid to be measured into a tank 17 where the liquid level is maintained constant by a return tube 23. Floating in the liquid in the tank 17 is a reference condenser 1 the dielectric of which is also formed in part by the liquid. Its capacity is of the form A+B(K - 1)/P where A is the condenser capacity when the dielectric is air, B is a constant, K the dielectric constant of the liquid and P its density. The measuring condenser 2 consists of the usual fixed immersion type condensers in parallel, the combined capacity of which is of the form C+D.V(K - 1) where C is the capacity when the dielectric is air, D is a constant and V the liquid volume whose weight is to be measured. A trimming condenser 3, series connected with the reference condenser 1, Fig. 1, across the secondary 7 of a supply transformer 5 is adjusted in value to the constant A so that the rectified current flow through the winding 9 of a ratio meter 9, 10, will, provided the impedance values of the elements concerned are appropriately selected, be proportional to the difference of the capacitances of condensers 1, 3, i.e. to B(K - 1)/P. Similarly the measuring condenser 2 is series connected with a condenser 4, adjusted in value to the constant C, across the transformer secondary 8 so that the rectified differential current flow through the meter winding 10 is proportional to D.V(K- 1). The quotient meter indication is thus proportional to V.P, i.e. the weight of the liquid volume V. The quotient meter may be as described in Specification 561,866.

Abstract: 1388630 Valves VIHORLAT NARODNI PODNIK 16 May 1972 [17 May 1971] 22869/72 Heading F2V The hydrostatic pressure in a liquid 4 is controlled by a body 3 of uniform cross-section partly immersed in the liquid and arranged to operate a valve which allows gas to flow into or out of a space 2. The effect of gas pressure on the body is counterbalanced by a piston 5 so that the valve responds only to changes in hydrostatic pressure. A member 9 applying an adjustable thrust to the member 3 in accordance with the required hydrostatic pressure is connected to a hand-operated controller 10, intermittent setting device 11 and a time relay 12. The body 3 may have a lower specific gravity than the liquid which may be molten aluminium alloy for pressure casting. In a second embodiment, the thrust is applied by pistons (16, Fig. 2) connected through a valve (18) to an air network (17) and a time relay (12). A bellows (7) replaces the piston 5.

Abstract: 654,052. Supply systems for consumption apparatus. STANDARD TELEPHONES & CABLES, Ltd. Aug. 21, 1947, No. 23185. [Class 38 (iv)] [Also in Group XXXIX] In a system in which unattended repeater stations receive operating power over the communicating line excessive voltage is prevented during periods of abnormal reduction in the equipment loading by switching into circuit suitable dummy loads. Fig. 1 illustrates such a system with " go " and "return paths, the power being transmitted from the controlling station CS over the phantom circuit of the two paths to the intermediate unattended stations RS1 ... 5. At each station the power is diverted by filters X to a mains unit M and the unconsumed power is reapplied to the line after voltage adjustment by an autotransformer T, through a further pair of filters X. A dummy load R3 equivalent to the power taken by the local mains unit for H.T. supply is connected when current relay PC is unoperated, e.g. during the heating of the filaments after the initial switching on or when the H.T. current falls, due to a local fault and a dummy load R4 which is equivalent to the load normally supplied by the output transformer T is under the control of a current relay LC and a sluggish no-volt relay NV, the latter of which prevents the load R4 being inserted while the load through LC is building up.

Title: Electric receivers for a remote controlled installation operating with synchronous selectors and employing audio-frequency currents superimposed on heavy current mains

Abstract: 646,505. Electric selective signalling. LANDIS & GYR SOC. ANON. Aug. 21, 1947, No. 23239. Convention date, Sept. 9, 1946. [Clase 40 (i)] [Also in Group XXXIX] In a receiver for a remote control system employing audiofrequency currents super-imposed on heavy currents, in which a synchronous selector is arranged to rotate in synchronism with a selector at the controlling station, false operation is prevented by a time lag device provided between a tuned receiving relay and the selector switch. In Fig. 1, relay E tuned by a condenser C to the controlling frequency energizes a slow to operate relay E1 and if the received signalling impulse is of sufficient duration a synchronous motor Sy driving the selector switch is connected to the power lines A, B, the motor circuit being maintained over an off-normal contact u until a contact arm D returns to its initial position. Impulses received whilst the arm D is rotating cause relays such as K1, K2 to operate according to the position of the arm when the impulses are received. Fig. 2 shows a similar circuit including a mechanical time lag device, comprising a bell-crank lever H which carries at its right-hand end a gear wheel R with a spring-controlled disc cam S attached. A coil K, when energized by relay E, swings the lever H and brings the gearwheel R into mesh with a gear-wheel Z driven by the synchronous motor, thus rotating cam S to operate the switch I, and connecting the arm D to the main B for the operation of relay K as before. Specification 494,792 is referred to.
