Title: Improvements in or relating to impedance matching devices suitable for use in high frequency transmission systems
IPC: H01P5/04
Filed: 1929-03-25
Abstract: 308,664. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Lindenblad, N. E.). March 23, 1928, [Convention date]. Coupling oscillating and radiating circuits; drying-out aerials.-High-frequency transmission lines are coupled to each other by connecting each line to symmetrical points on a linear oscillator, the connecting-points being chosen so tHat the impedances of the lines are matched. Condensers are provided to prevent the short-circuiting of direct or low-frequency current that may be sent though the lines for melting sleet deposits &c. As shown in Fig. 1, the input line 2, 4 and the output line 6, 8 are connected to symmetrical points on the linear oscillator 10. Radiation may be reduced by bending the oscillator into U form. Fig. 4 shows such an arrangement with the oscillator duplicated, and with condensers 30 connected at the potential nodes of the oscillators 10, 20. In Fig. 5, the two U-shaped oscillators 10, 20 are connected at their current nodes to form a loop. Fig. 6 shows a practical form of the coupling, with the oscillators 10, 20 forming a loop 40 connected by strain insulators 22 - - 28 to the input line 2, 4 and the branched output line 6, 8. The condensers 30 are formed by overlapping lengths of wire separated by insulation, and one condenser bridge may be adjustable to tune the coupling. Tappings 50, 52 for the input and output lines are adjustable along the oscillator wires. A similar arrangement may be employed for single wire lines (Fig. 7, not shown).

Title: Switching circuits
IPC: G11C11/44
Filed: 1961-03-17
Abstract: 975,266. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 17, 1961 [March 30,1960], No. 9773/61. Heading G4H. [Also in Division H3] To avoid errors due to broken connections in a switching circuit (e.g. a printed superconductor circuit) the circuit includes alternative current paths. In Fig. 1, a terminal 55 may be connected over alternative paths X1 X2, X3 to one of three identical loads 15, 16 and 17 by operation of flipflops 20, 21 and 22 in a suitable code. Operation of flip-flops 20 to 22 in the code 110 connects load 15 over conductors X1 and blocks alternative conductors X2, X3. The flip-flops are controlled by circuits 30, 31 and 32. These circuits are operated by code signals and include alternative paths which automatically come into service on failure of a main path. Control circuit 31, Figs. 3, 5. Code signals on conductors W1, W2, W3 select a control circuit and a flip-flop and a signal on one of the conductors V1, V2, V3 individual to the three control circuits sets the selected circuit to 1 or 0. With signals 101 on conductors W1, W2, W3 and 1 on V2, current flows from terminal 101 to terminal 102 over conductors 175, 177 and operates cryotron 82 to set flip-flop 21 to 1. Parallel conductors 111, 130, 150, 170 &c. are all driven resistive by the selection signals. If conductor 175 is interrupted, the current flows through resistive conductors 111, 130, 150, 170 in parallel through conductor 179 which is superconducting and cryotron 83 to terminal 102 as before. Flip-flop 21 is set to 1 as before. If the code signal does not select the circuit shown in Fig. 1, conductors 175, 177 and 179 are resistive and the parallel conductors provide at least one superconducting path for the current flow to terminal 102 without operating the flip-flop 21. Fig. 5 includes cryotrons for setting flip-flop 21 to 0 and is otherwise like Fig. 3. Similar alternative paths may be provided for vertical conductors as well as horizontal conductors but no embodiment is described.

Filed: 1934-03-29
Abstract: 435,815. Valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, and GOODENOUGH, E. F., 383, Watford Way, Hendon, both in London. March 29, 1934, No. 9859. [Class 40 (v)] In a thermionic amplifier, the output of which is applied to a Kerr cell, the attenuating effect due to the capacity of the cell is compensated by including an impedance in series with the cell, the voltage across which is applied to the input circuit of the valve driving the cell or to the input of any one of the preceding amplifier valves in such phase and amplitude as to oppose the undesired component. In the arrangement shown, the required compensating voltage is derived from the undesired voltage component in the cell circuit proper by connecting the cell K to a resistance GL1 in the anode-cathode circuit of the next but one preceding amplifier V1, thereby ensuring that the amplified component in the output of V3 is in phase opposition to that injected at T1. If the amplifier comprises only two valves the cell connection T1 is returned to a tapping on the grid circuit input resistance of the penultimate amplifier, Fig. 4 (not shown). The cell K may be followed by a further amplifying valve from the anode circuit of which a capacitative coupling is fed back to the grid circuit of that feeding the cell, Fig. 7 (not shown). The connection T1 of Fig. 3 may be made on the anode resistance of V1 instead of on GL1, Fig. 5 (not shown).

Title: Improvements in and relating to electrical capacitors
Inventor: GAUT GEOFFREY CHARLES
IPC: H01G13/00
Filed: 1955-04-05
Abstract: 836,392. Folding paper. PLESSEY CO. Ltd. June 6, 1956 [April 5, 1955], No. 9925/55. Class 100(1) [Also in Group XXXVI] In a process for making an electrolytic capacitor, conducting strips from reels 34 and 36 are assembled with porous paper strips from reels 42 and 43, the composite strip thereafter being folded in a zig-zag fashion by a mechanism 21 shown in greater detail in Fig. 4 and then carried forward by combs 80, 81 fitting within the folds in the strip to mechanism 24 where the composite strip is cut into suitable lengths. The strip from reel 34 preferably comprises cotton gauze which has been sprayed with aluminium on both sides to form a porous metallic surface, while the strip from reel 46 comprises an etched aluminium foil. The folding mechanism 21 comprises a pair of rollers 52, 53 through which the composite strip is led. These rollers are actuated by a cam-mechanism 56 whereby they are moved together in a reciprocating motion in a vertical direction; simultaneously the cam mechanism controls bifurcated guide members 60, 61 which move both horizontally and vertically in synchronism with the rollers 52, 53 so that the composite strip passing between the rollers is folded alternately in opposite directions. Thus from the position shown, member 61 rises to mesh with member 60, then the rollers descend to fold the strip about one prong of the member 61, member 60 subsequently moving upwards and when clear of member 61 to the left and then down again to engage once more with member 61. The rollers then move upwards to form a further fold and so the process continues with upper and lower folds being formed alternately. The folded strip issuing from the mechanism 21 is carried forward by combs 80, 81 which are actuated by the cam mechanism 83 shown in greater detail in Fig. 5, so that they rise alternately and engage the folds of the strip and then move in the forward direction carrying the strip forward. A cam-operated blade 99 is periodically inserted in the path of the strip to compress the folds as they leave the combs 80, 81; then when the blade is withdrawn the compressed strip passes down the channel 22. As it emerges from the channel it is cut into suitable lengths by cutting mechanism 24. Electrolyte is discharged on to the strip from the pipes 92 and 102. It is stated that the folding process may be arranged so that periodically a larger fold may be made. Such a fold may be used to mark the end of a section or to facilitate making connection to an electrode of the capacitor. Specification 833,984 is referred to in the Provisional Specification.

Class 6(i) [Also in Group XXIV] Relates to manure-spreaders of the endless-conveyer and rotary-beater type wherein the conveyer 14 is driven intermittently by pawl and ratchet 'mechanism 48, 49 coupled by a link 44 to a rocking lever 34 actuated by the land-wheels or some other source of power. According to the invention, the ratio of the arms of the lever 34 is adjustable to vary the stroke of the pawl 48. In Fig. 3, the conveyer 14 is driven from the main beater shaft 24 by a crank 29 and connecting-rod 31 coupled to a collar 33 at the upper end of the rod 34. The rod is slidable in a sleeve 39, pivoted to the chassis and constituting the fulcrum. The collar 33 and rod 34 can be forced upwardly, against the tension in a spring 55, by a manually-operated cam 51, thereby decreasing the stroke of the pawl-carrying pivoted lever 46. In Fig. 6, the land-wheel axle 11 carries a star-wheel 1 which oscillates a bell-crank 64, 66 pivoted on the chassis, the lower arm 66 of the bell-crank being linked to the pawl-carrying lever 68 driving the ratchet 69: The effective length of the arm 66 is variable by raising the link 67 through a pivoted trangular lever 79. A spring 83 pulls a roller 76 into contact with the arm 66 and a roller 65 into contact with the star-wheel 1. Specification 588,514 is referred to.
