Abstract: 120,677. British Thomson - Houston Co., (General Electric Co.). Feb. 5, 1918. Transformers. - In a high-frequency electric supply system, an alternator having a number of independent armature circuits arranged in groups connected to the load through a transformer whose primary is composed of a number of groups of independent windings, each winding being in a completed electric circuit with one armature circuit only, thereby preventing the direct flow of cross currents in the armature circuits. An alternator having thirty-two independent armature circuits has them arranged in four groups of eight; one of these groups is shown in Fig. 3, the armature circuits 14 being connected to bus-bars 17. The transformer windings are similarly grouped into sets of eight primary and secondary coils. Each primary coil consists of eight conductors 15, each of which is connected at one end through the bars 17 to one armature circuit only, the other ends of the eight conductors are connected in common to a binding-post 18 and through a reactance coil 19 to earth. The binding-posts are connected by a common return to the other ends of the armature circuits. The secondary windings are connected to sets of bus-bars, the groups of secondaries being arranged in series, parallel, or seriesparallel. The transformer is mounted on top of the alternator. In building the transformer the primary is made of cables having eight conductors and the secondary of cables with four conductors. These may be placed alternately and parallel to one another, or, as shown in Fig. 6, the primary and secondary coils P, S may be spirally arranged, the secondary being outside the primary

Abstract: 552,947. Measuring voltages. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Feb. 18, 1942, No. 2159. Convention date, Feb. 18, 1941. [Class 37] A replica distribution network 11 energized by an A.C. source 14 comprises a number of load-representing impedance devices 18, 181 in the form of series-connected resistance and inductance connected between each of the points A ... D and the neutral. The values of impedance and their power-factors are so selected that they simulate loads in the actual network when energized by a calculated voltage. In case the actual measured voltage of meter 44 differs from the calculated voltage, it is necessary to adjust the actual voltage without changing the impedance value or power-factor. Accordingly a transformer or, as shown, an autotransformer 24 is provided and comprises a winding 28 with, for example, 10 per cent of it divided into one per cent taps and led out to contacts of a switch. The movable contact 36 and lowermost tap thereof are connected to the lower contacts 38, 32, respectively, of a reversing switch 34, the centre contacts 39, 40 of which are connected, respectively, to the network 11 and the impedance. In the lower switch position, the voltage across the impedance can be progressively reduced to bring the measured voltage at 44 into agreement with the calculated voltage, whereas in the upper position the untapped winding is connected between the network and neutral and a greater voltage can be impressed across the impedance by inserting more of the tapped winding. An ammeter 46, voltmeter 50, and wattmeter 48 can be connected selectively to the circuit by plugging in the metering buses or by the means described in Specification 551,194.

Title: Improvements in or relating to kilns for burning clay products, glazed ware and pottery
IPC: F27B13/02
Filed: 1927-01-27
Abstract: 291,482. Webster, H. Jan. 27, 1927. Pottery and like kilns; multiplechamber kilns.-In a pottery or like kiln, of the kind having around its periphery two series of fireplaces serving to fire the kiln with updraught and downdraught respectively, only one series is in operation at a time, the gases from that series passing through the whole of the contents of the kiln. In the right-hand kiln shown in Fig. 2, the gases from the downdraught fireplaces a pass over the bag wall d and through the perforated floor e into the well f; the left-hand kiln shows the updraught fireplaces b which alternate with those of the other series a and deliver the gases upwardly through the floor e into the kiln, whence they pass downwardly behind the wall d to an annular flue h. Fig. 3 shows part of a battery of kilns connected for continuous work- .ing, dampered flue connections being provided so that the waste gases from any kiln, whether working with updraught or downdraugbt, may be passed to any other kiln or kilns of the series or to driers &c. The gases from the right-hand downdraught kiln shown in Fig. 2 pass from the well f through an opening n into a longitudinal flue m running the whole length of the battery and fitted with dampers i, by suitable manipulation of which the gases may be caused to pass in either direction and upwardly into the adjacent kiln. If the dampers i between the kilns be closed, the gases pass from the flue m into the cross-flues o, from which, by operating suitable dampers, they can be caused to pass direct to a chimney k, into a flue p, and thence to any kiln of the series, or into a waste-gas flue q leading to driers or other waste-heat utilizing apparatus. Similarly, the waste gases from a kiln working with updraught pass from the flue h of that kiln through a connection l to the flue h of the adjacent kiln, from which they pass into the longitudinal flue m and thence directly to the next kiln or into the cross-flues o as desired. The invention is also applicable to muffle-heated kilns for firing terra-cotta or other ware with which contact of combustion gases is not desirable. Specification 269,344 is referred to.

Title: Pulse sequencing system
IPC: G21C7/36
Filed: 1970-01-19
Abstract: 1282223 Control of reactors WESTING- HOUSE ELECTRIC CORP 19 Jan 1970 [13 Feb 1969] 2419/70 Headings G4H and G6C A system for generating electric control pulses to cyclically raise or lower nuclear reactor control rods arranged in banks is adjustable to accommodate different numbers of control rods per bank and/or different numbers of banks while maintaining the pulses for a bank evenly timespaced. A clock 10 drives a counter 30 either forwards or backwards through AND gates 18 or 20. The capacity of the counter is equal to the least common multiple of the factors comprising the factorial of the maximum number of rods ever likely to be in a bank. The counter is decoded to provide pulses on leads P in turn, the number of leads being equal to the above maximum number of rods. In a selector 42 a number of decoder outputs, equal to the number of rods present in a back and evenly time-spread, are multipled to banks of AND gates, each bank being energized in turn by bank control signals (44), so providing sequential control pulses to each bank in turn.  Upon start up or a change in direction of the control rod movement, a fast pulse generator 182 is used to obtain the first control pulse of the new sequence, which via OR-gate 186 then inhibits the generator 182 in favour of the slower pulse generator 10. With a change of direction unit 190 inhibits the first control pulse P of the new sequence to ensure that the last rod moved in the previous direction is the first to be moved in the new direction.

Ceramic products from carbonaceous shales of the type disclosed in Specification 931,185 are fired in a Hoffmann kiln comprising a treatment chamber divided by a central well 21, Fig. 8, a peripheral waste gas flue 24 with diagonally opposite offtakes 27 respectively controlled by dampers 28 and 29, and apertures 25 each controlled by a damper 26 joining said chamber and said flue. During the initial heating period when considerable evolution of combustible substances takes place, the temperature is controlled by supplying an excess of air through roof ports 8, Fig. 5, and extracting large quantities of waste gases through dampered openings 6 into waste gas flue 4. The waste gases may be used for drying the ware. For a time combustion of evolved substances makes the firing process self-sustaining, but eventually, and particularly when glazing, cool dust is supplied through roof ports 9. In the final cooling zone 11 cooling air supplied through roof ports 10 passes partly in the direction of the arrow 15 to join the waste gases and partly through dampered openings 6f direct to the flue 4.

Abstract: 897,840. Printed circuits. HUGHES AIR. CRAFT CO. Jan. 24, 1961 [March 30, 1960], No. 2821/61. Class 37. A grid for interconnecting small components comprises a first and second set of substantially flat electrical conductors which intersect but are insulated from each other; each conductor of the second set having a plurality of tab portions extending therefrom and making electrical contact with conductors of the first set. Electrical continuity of any conductor may be interrupted by breaking the conductor, and the continuity between a selected conductor of the first set and a selected conductor of the second set may be interrupted by breaking the associated tab portion. A glass or other insulating material base 14 has a row of horizontal conductors 10 and vertical conductors 12 separated by insulating material 32, the vertical conductors 12 being furnished with a plurality of tabs 16. The conductors 10 are formed by vacuum-depositing alternate layers of permalloy and copper 26, 28, 30 respectively in Fig. 4 and then using a photo-etch process to form the parallel conductors. After deposition of an insulating layer 32 of silicon monoxide over the conductors 10 apertures 34 are sand blasted in the insulating material so as to lay bare the conductors 10 at the required positions. The vertical conductors 12 and tab portions 16 comprising permalloy layers 36, 40 and copper layer 38 are then formed by vacuum deposition end photo-etching in a similar manner to conductors 10. Finally if it is desired to break the electrical convection between a selected horizontal conductor 10 and a vertical conductor 12 a portion of the tab 16 is removed as shown at 20, Fig. 2. Similarly vertical conductors 12 may be broken as at 22, and horizontal conductors 10 may be broken by removing the whole of a tab 16 and part of a conductor 10 as at 24. The breaking of electrical connections at 20, 22, 24 is carried out by applying a mask to the finished grid and etching away the unwanted metal.

Abstract: 1,134,162. Making metal fabrics and wire. UNION CARBIDE CORP. 19 Jan., 1967, No. 2869/67. Heading B3A. [Also in Divisions C7, E1 and H1] A process for the production of metal fibres, fabrics and other shapes comprises: 1. Impregnating a preformed organic polymeric material shape with a compound of one or more of the metals of Groups I B , VI B  or VIII of the Periodic Table, Tc, Re or Zn. 2. Heating the impregnated material to carbonize and then volatilize the organic material without ignition. 3. The product of step 2 is then heated in a reducing gas to reduce it to the metallic form. The organic material may be for example cellulosic (rayon, saponified cellulose acetate, cotton, wood or ramie), proteinaceous (wool or silk), acrylics, polyesters, vinyls or polyurethanes and may be in the form of ribbons, staple fibres, yarn and roving, woven cloth, knits, braids, felts and papers. The organic material may be pretreated with a suitable solvent to swell it prior to treatment with a solution of the metal compound(s) which may be conducted at an elevated temperature. The treated material then has the excess solution removed by blotting, washing, blowing with a gas, vacuum filtration, or centrifuging. The heating in step 2 is preferably carried out in an oxidizing atmosphere (e.g. in the presence of O 2 , NO 2  or SO 3 ) to oxidize the metal compound and to aid the volatilization of the organic material. The reducing gas in step 3 may be CO or NH 3  but H 2  is preferred.
