Filed: 1938-10-24
Abstract: 520,500. Electric control systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., ROSEBY, P. N., and MACKENZIE, J. F. Oct. 24, 1938, No. 30727. [Class 40 (i)] [Also in Group XXXIX] High frequency signals are transmitted over a polyphase high-tension supply network and the associated low tension networks by a singlephase high-frequency generator connected to phase wires of a low tension network so that the signals appear on all phases of the high and low tension networks of the system. In modifications, the generator may be connected to the high tension network by a transformer, and the connection may be between two phase wires and neutral. In the upper of the two arrangements shown, the generator G is connected directly to phase 1 of a 4-wire 3-phase low tension network supplied over T1 from the high tension network HT 1-3, and over condensers C1, C2 to phases 2 and 3, the condensers being of substantially the same value which is such as tune the circuits to the high frequency and offer high impedance to the supply frequency. The signals may be received 'as shown at B on another 4-wire 3-phase low tension network or on any other type of network such as a Scott-connected 6-wire 2-phase network. In the other arrangement the generator is connected to wires A2, B2 or A1, B1 of a Scott-connected network, the neutrals N of which are connected together. The generator may be of the thermionic oscillator or high frequency alternator type and the receiving relays may be of the cadence type as described in Specification 518,877.

Title: Pressurised gas circuit breaker with multiple interruption
IPC: H01H33/00
Filed: 1963-08-06
Abstract: 980,247. High voltage switches. BROWN, BOVERI & CO. Ltd. Aug. 6, 1963 [Aug. 7, 1962], No. 30913/63. Heading H2B. In a compressed gas circuit breaker having multiple series connected interrupters 3c and isolators 2c, the interrupters are in pairs in twin chambers on insulator columns 3 while the isolators are in chambers supported by a separate insulator column 2 and constantly subjected to the gas pressure in a reservoir 1 through at least one of the insulator columns 3 supporting the interrupters. Upon the application of an electrical pulse at 10a an electromagnet 3l opens a valve 3h to admit compressed gas from the reservoir 1 to the underside of a piston 3f which opens an operating valve (not shown) in the interrupter head through a connecting rod 3d. Simultaneously an electromagnet 8c releases a latch to open a valve 8a passing compressed gas through a line 9 to the operating valve 2h of the isolators at the foot of insulator column 2, thus opening the isolators a short while after the interrupters but before the latter reclose. The circuit breaker is reclosed by venting line 9 through a valve 8d opened by a latch tripped by a further electromagnet 8f. Upon failure of one or other of the electrical connections 10, 10b, the operating sequence is preserved by means of conduits 3r, 3q.

Title: Continuous process of calcining coke
IPC: B01J6/00
Filed: 1963-08-06
Abstract: A continuous process for calcining coke comprises passing coke particles and an oxidant concurrently into a combustion zone under conditions such that only a minor portion of the coke is oxidized, e.g. 2 to 25%, preferably 5 to 10%, by weight.  The oxidant is oxygen or an oxygen-containing gas, or fluorine or chlorine, or nitrogen dioxide, and temperatures in the combustion zone lie in the range 540 DEG  to 1400 DEG  C., preferably 815 DEG  to 1360 DEG  C.  In the example illustrated, coke, which is preheated, e.g. by recycled gas, is fed downwardly into a retort to which the oxidant is delivered, the combustion zone being stabilized by regulating the volumes of the coke and oxidant.  In another example, a stationary column of coke is supplied with air at the top, the combustion zone travelling up the column.

Title: Printing apparatus
IPC: H04L17/30
Filed: 1954-10-27
Abstract: 765,059. Selective printing. ROSEN, L., BARLOW, H. C., and BOWMAN, R. L. Oct. 27, 1954, No. 30978/54. Class 100(4) [Also in Group XL(b)] A printing device comprises a rotatable type wheel or a series of type wheels 11, 12, 13 and means to effect printing, e.g. printing hammers 14, which are controlled by an impulse generator for producing pulses of electric current during the period of rotation of the type wheel, the timing of the pulses being identical with the timing of the. movement of the type wheel relative to the printing means. The impulses are generated by a pole piece 36, rotating on the type wheel shaft as it passes a series of coils 30 spaced around a support 30. The particular coil which generates the impulse is determined by the selective operation of switches 33 which may be mechanically operated from a keyboard, a punch tape or card, a computer &c. This impulse changes -the bias of the thyratron 46 which thereby conducts, and so discharges a condenser 39 and operates an electromagnet 15 which causes a hammer impression to be made. The discharge of condenser 39 drops the anode voltage of the thyratron 46 which then ceases to conduct. The circuit to condenser 39 is opened by means of a switch 38 so that recharging of condenser 39 is prevented. Usually between 30 and 50 type wheels are used, each of which requires its own thyratron circuit, but common coils 30 may be used. In an embodiment described with respect to Fig. 2 (not shown) the keyboard &c. presets a mechanical or electrical counter and the impulses from the generator coils 30, all of which in this instance are connected in parallel, are fed into this counter when permitted by a "gate circuit." The gate circuit permits the pulses to reach the counter once for each rotation of the rotating pole 36 which energizes a separate coil in the "0" position of the type wheel. The counter operates a thyratron circuit in a manner similar to that previously described. In an alternative of the last modification the pulses may be generated by multiple pole piece from a single coil, and in a further embodiment the pulses are generated by light energized cells as shown in Fig. 3 (see Group XL(b) ).

[Class 7 (iii)] A combustion chamber 4 in each cylinder head is in the form of a solid of revolution and communicates with the cylinder through an orifice 5 arranged eccentrically relatively to the axis of the cylinder and to the axis of the chamber, the piston 8 has a projection 9 penetrating into the combustion chamber, the exhaust valve 2 but not the admission valve is located in the chamber and the injector 6 is arranged so as to. direct jets of fuel between the two hot walls formed by the exhaust valve and the boss of the piston opposite this valve. The projection 9 co-operate ing with an inclined passage 10 at the end of the compression stroke forces the air tangentially into the combustion chamber. The fuel injector is arranged at an inclination and so as to direct the fuel oppositely to the circulation of the air in the chamber 4. This chamber may. be more or less spherical or torus-shaped. The head of the inlet valve 3 is level with the end of the cylinder. An igniter may be arranged opposite to the injector. In a modification, Fig. 5, the injector 6 gives three lateral jets of fuel 131, 13<2>, 13<3> and the air compressed into the chamber first enters the chamber 4 tangentially, meeting mainly the outer jets 13<1> and 13<3>, but finally is directed through a groove 27 in the piston projection, so as to meet the middle jet 13<2>. The piston projection may be formed separate, and be attached thereto by a bolt.

Abstract: 1,149,284. Leak detecting. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ, N.V. July 10, 1967 [July 12, 1966] No.31707/67. Heading G1S. [ Also in Division H4] In a pipe-line leak detector, a measuring device passed through the pipe-line monitors detected acoustic signals in two frequency bands, one of which is at or near the predominant frequency generated by leaks and the other of which is above this frequency. Leak noise and background noise can thus be distinguished, since leak noise is stated to decrease sharply in intensity above the predominant frequency whereas background noise is not significantly different in the two frequency bands. In one embodiment the outputs of two tuned amplifiers (43KHz and 53KHz) fed simultaneously from a microphone are integrated and then compared in a differential voltmeter, and the difference voltage is recorded. In a second embodiment the equipment is switched alternately between the two frequency bands a few hundred times per second. Alternatively, signals in the two channels are recorded on tape for subsequent play-back and comparison.

Title: Method of and means for the continuous production of glass tubing  by centrifugal casting
IPC: C03C21/00
Filed: 1971-07-07
Abstract: 1356630 Producing glass tubes KOMBINAT TECHNISCHES GLASS ILMENAU VEB 7 July 1971 31850/71 Heading C1M Glass tubes are continuously formed from glass forming material by casting the material on to one end of a rotationally symmetrical internal surface formed by rotating a liquid layer immiscible with said material, the material before or after casting being heated to the required viscosity and the material after casting being caused to slide along the liquid surface and its viscocity increased by cooling whereby the completed tube may be withdrawn from the other end of the surface. During rotation of the liquid layer some liquid is withdrawn from the layer, treated (e.g. purified) and subsequently returned to the rotating layer. The method may be carried out by casting molten glass on a liquid layer 2 contained in a rotating drum 1 inclined at a small angle to the horizontal and having inwardly projecting ribs 32 to transmit rotation to the liquid. The drum has at each end shields 8 and outside shield collectors 12, 12<SP>1</SP> provided with means for introducing and maintaining a protective gas. Solid material may be cast on to the liquid in which case a centrally located electrical heater is provided within the drum to melt the material (Fig. 2, not shown). The solid material may be cast on to a first glass layer to provide a multi layered tube. The material may be such as to produce foam glass upon heating. In a modification molten glass is fed into the base of a vertical chamber in which the liquid is rotated by means of a stirrer or by a stator which produces a rotating magnetic field. The finished glass tube is continuously withdrawn upwardly. In each of the above processes the liquid may be one metal, e.g. tin, a metal alloy, e.g. tin and silver, a salt, metal oxide or a mixture thereof. The surface of the liquid may be protected from oxidation by a gas (e.g. a H 2 /N 2  mixture) or a layer of molten salt (e.g. NaCl/KCl mixture). During rotation the glass may be subject to an electric current to promote ion exchange between the liquid and glass.
