Title: Improvements in or relating to control circuits for high voltage lines
IPC: H02H3/30
Filed: 1961-02-02
Abstract: 956,675. Protective arrangements. SIEMENS & HALSKE A.G. Feb. 2, 1961 [Feb. 2, 1960], No. 3983/61. Heading H2K. In a protective arrangement in which phase comparison is effected between the currents at the ends of a protected line or section, the equipment at each end of the line includes a limiter B 1 which produces a rectangular voltage wave from a voltage derived from the line current. This rectangular voltage wave is applied to a keying modulator M1 supplied from frequency generators G1, G2 producing two different frequencies, the output of the modulator M1 comprising alternately the two frequencies. The rectangular voltage wave is also applied through a delay network LG and rectifier Cr1 to a synchronizing generator G3, the output of which is converted to a rectangular wave by a limiter B2. This rectangular wave is phase-displaced relative to that from the limiter B1 and controls a modulator M2 so that it passes the output of the modulator M1 as a series of dual frequency pulses which are transmitted to the other end through an amplifier V1 and filter F1, the transmission from the two ends being of the same frequencies but occurring alternately. At each end, the combined transmissions are received by a filter F2 and pass through an amplifier V2, limiter B3 to filters F3, F4, each of which is tuned to one of the two frequences. The outputs of these filters are rectified by rectifiers Gr2, Gr3 and energize opposing windings of a relay RL2 having contacts rl2 in a control circuit UK. A relay RL1 energized by the rectangular voltage wave from B1 also has contacts Rl1 in the circuit UK. When the line currents at both ends have the same phase angle, i.e. any fault is external to the protected section, the contacts rl1 and rl2 assume simultaneously the positions T or Z and the control circuit is always closed. Under internal fault conditions, the phase angles are not the same with the result that the relay contacts do not occupy the same positions and the circuit UK is opened to cause the interruption of the protected line or section. When a fault occurs a relay RL3 opens its contacts rl3 to interrupt the supply to the generator G3 which continues to oscillate for a sufficient time to enable the equipment to operate and so avoids incorrect synchronizing of the transmissions.

Abstract: 644,000. Escapements. CLIFFORD, C. F. Feb. 12, 1947, No. 4109. Addition to 596,216. [Class 139] The magnetic escapement of the parent Specification is modified by the provision of a wavy magnetic path which is not endless. As shown in Fig. 1 the poles b of a rotary escape wheel a co-operate magnetically with tongues in split-rings c\ c<SP>2</SP>, c<SP>3</SP>, c<SP>4</SP> carried by an oscillating member. In another embodiment (Fig. 3, not shown) the invention is applied to a lever escapement, the lever of which is provided with a short wavy magnetic path which cooperates with studs on the escape wheel. In another example the split rings c\ c<SP>2</SP>, c<SP>3</SP>, c' are provided with two diametrically opposite set of tongues as in the first example and are disposed between two polar escape wheels mounted on the same shaft. In another embodiment, Fig. 6, a drum 6b on the balance staff is provided with a wavy path 6c with which co-operate soft iron pins 6h on two rotating discs 6f of transparent plastic. The poles 6i of a permanent magnet provide the magnetic field for the path 6c and the pins 6h. At the top the balance spindle may have a small pin of magnetisable material which pin may be bent more or less into the magnetic field and thereby modify its reluctance and effect a control of the speed of oscillation of the path at varying amplitudes. The drum 6b may be provided with non-magnetic laminations 6p to act as a mechanical obstruction to the pins 6h so preventing momentary excess movement of the wheels 6f. In a further embodiment, Fig. 7, a pendulum 7a has at its upper end a U-shaped permanent magnet 7b. Secured to the poles of the magnet are wavy soft iron paths 7e, 7f which cooperate with soft iron pins 7i carried by the escape wheel 7g. A pin may be fixed between the poles of the magnet to provide a mechanical lock for the escape wheel (Fig. 7A, not shown). In another embodiment (not shown) a vibrating reed has an inertia weight in the form of a permanent magnet which carries a raised wavy soft iron path which co-operates with pins on the periphery of an " escape drum " which also carries additional pins which abut the path to provide a mechanical safety lock. In another example (Fig. 9, not shown) a balance wheel carries the wavy path which co-operates with pins on the escape wheel and a permanent magnet again provides the magnetic field. In a further example, Fig. 10, the wavy path is placed on the escape drum 10a and co-operates with the poles of an oscillating ring magnet 10d.

Abstract: 735,866. Centrifugal and screw pumps. ROLLS-ROYCE, Ltd. May 15, 1953 [Feb. 15, 1952], No. 4150/52. Class 110 (1). [Also in Group XXVIII] In a fuel pump, a pipe or conduit is provided, with an inlet at or near a location at which free air or vapour collects, and a stream of fluid is produced in the pipe or conduit to withdraw the air or vapour and entrain it in the fluid stream. Fig. 1 shows a fuel pump submerged in a fuel tank 10 and driven by an electric motor 15. Fuel under pressure is tapped off from the volute 12a and passes through a pipe 20, gland 19 and bores 18a and 18 in the driving shaft 14 to a nozzle 21. The nozzle discharges into a venturi 22 leading to a drain pipe 23 which preferably discharges to the tank 10. The nozzle and venturi form an injector which withdraws air or vapour accumulating in the central space 16 and entrains it in the jet of fuel issuing from the nozzle. In the fuel pump shown in Fig. 3, air or vapour liberated at the periphery of the impeller 35 passes through an annular gap 38a to a manifold 38, from which it is withdrawn by an injector comprising a nozzle 41 and venturi 39 and discharged through a pipe 40. The entraining fluid comprises fuel under pressure supplied to the nozzle 41 from the volute 36. The manifold 38 may have more than one outlet. The impeller 35 may be of the helical or helicocentrifugal types. Fig. 2 shows a modification of Fig. 1, but a similar modification may be applied to Fig. 3. The venturi 22 is replaced by a plain pipe 24 leading to a discharge pipe 25 having a venturi portion 25b. Entraining fuel is fed from the volute 12a through a pipe 27 to a nozzle 26. An additional nozzle 28 may be provided, fed with an inert gas such as nitrogen. The inert gas, mixed with fuel and air, passes through the pipe 25 to the fuel tank and forms a non-explosive atmosphere above the free surface of the fuel. In any of these embodiments, the fuel used for operating the injector may be derived from the exhaust of a hydraulic motor which drives the pump and is fed with motive fluid from a main fuel pump which is connected in series with the pump, as described in Specification 735,874.

Title: Improvements in or relating to vitreous coatings
IPC: C23D5/02
Filed: 1941-04-04
Abstract: 547,532. Transformers. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 4, 1941, No. 4518. Convention date, April 10, 1940. Drawings to Specification. [Class 38 (ii)] [Also in Groups XXIII and XXXVI] A method of applying a vitreous coating to an article consists in using a polymerized resin as a carrier for a vitreous frit, the resin being of such a nature that it depolymerizes and evaporates at the temperature to which the coated article is heated to fuse the frit into a glass. Polystyrene and methyl methacrylate resins are suitable and they are mixed with a suitable solvent such as toluene or benzene, a plasticizer being added if necessary. A frit suitable for application to copper consists of 3.5 per cent of K 2 O, 1.5 per cent of Na 2 0, 38 per cent of Sc0 2 , 51.4 per cent of P 3 O, 0.4 per cent Ca 0, and 5.5 per cent of AS 2 O 3 . Other frit compositions are given in the Specification. The mixture may be applied as a coating to an electric conductor and dried at a relatively low temperature to form a varnish-like film. The conductor may then be shaped to any desired configuration and heated to drive off the resin and fuse the frit into a vitreous coating. A conductor shaped and coated in this way may be used as a heating resistance, or for building a dry-type transformer which has no liquid dielectric and is operated at high temperature. In such cases, graded particles of refractory material, such as silicon carbide or zirconium oxide, may be mixed with the composition. The particles do not fuse and serve as spacing members for preventing neighbouring turns of a coiled conductor from touching one another during the fusion of the frit.
