Patent GB-665072-A (GB)
Title: Improvements in or relating to a method and means of translating coded pulses
IPC: H03M1/00
Filed: 1949-10-31
Abstract: 665,072. Pulse code modulation circuits. GLOESS, P. F. M., and LIBOIS, L. J. M. Oct. 31, 1949 [Nov. 13, 1948], No. 27885/49. Class 40 (v). Amplitude modulated pulses are converted into code pulse groups by successive comparisons of a fixed reference voltage and the amplitude of the input pulse in a comparator circuit in which a code pulse is generated if the input pulse exceeds the reference voltage, a pulse of the difference amplitude being doubled and fed back to the comparator and in which, if the input pulse is exceeded by the reference voltage, no code pulse is generated and the unchanged input pulse is doubled and fed back to the comparator. In the embodiment described, a negative amplitude-modulated pulse 3 from terminal 2 is reversed in valve 1 and applied to the grids of valves 35, 36. If the reference voltage provided by the bias source 7 is overcome, valve 35 passes on a negative code pulse 17 to the output terminal 10 for subsequent shaping and transmission and to valve 8 which is thereby blocked. At the same time, valve 36 passes a pulse 15, representing the subtraction of the reference voltage from the input pulse amplitude, through a delay line 11, which determines the code pulse interval, to an amplitude doubling valve 32, which feeds a fresh input pulse to valves 35, 36. If an input pulse fails to overcome the reference bias source 7, no code pulse is produced, valve 8 remains unblocked and the input pulse is passed on through this valve, unchanged in amplitude, to the delay line 11 and doubler 32. In order to terminate the coding operation. when the correct number of code pulses has been generated, the input pulse from terminal 2 is also fed to a delay line 14 of the required time constant which feeds the delayed pulse to a valve 33, the positive output pulse from which cancels the negative unwanted pulse at the grid of the doubler 32.

Abstract: 390,817. Cable joints. STANDARD TELEPHONES & CABLES, Ltd., SCOTT, T. R., and WEBB, J. K., Connaught House, Aldwych, London. Oct. 9, 1931, No. 28039. [Class 38 (i).] In an electric power cable joint the effective length of the breakdown path through the oil is increased by the use of insulating beads (preferably of polymerized styrene) disposed in the medium. In making the joint the cable ends are prepared in the usual way and after placing a sleeve 2 over the end of one cable, the contiguous cores 1 are spliced. The sleeve 2 which has a mouth 4 and outlet pipe 5, is then moved into position and filled with clean dry dielectric beads and the lid 6 pressed tightly down and sealed in position. The sleeve is then wiped to the lead sheath 7. After evacuation of the sleeve, dry degasefied oil is sucked in through the inlet pipe 8, which with the outlet pipe 5 is afterwards sealed off. Modifications of this method of preparing the joint 'are described.

In order to insert the cassette, it is positioned so that a flat 104 on a mounting bar 102 passes through the eye 52 and is then rotated for the pin 76 to slide up ramp 68 and engage in hole 66. Release of the cassette is effected by rotating pin 82 to withdraw the pin 76. In order to record or play-back, a solenoid 94 is actuated drawing pin 76 downwards, thus rotating the cassette about rod 102 until the roller 32 engages with capstan 132. A screw 70 is provided to adjust the cassette in the drive position. The two ends of the tape are joined to form an endless loop by a transparent section and when this passes in front of a lamp 40, light from it falls on a photocell 128 to stop the drive. Alternatively drive may be stopped manually. A number of similar cassettes may be mounted side by side between a common mounting bar 102, Fig. 3, and individual pins 76, the capstan 132, driven by motor 142, being common to all cassettes.

Title: Pulsed electric heating system
Inventor: VANDIVERE EDWARD J
IPC: H05B3/26
Filed: 1966-06-24
Abstract: 1,141,889. Automatic temperature control systems. REYNOLDS ELECTRICAL & ENGINEERING CO. Inc. June 24, 1966, No.28488/66. Heading G3R. An electric panel-type space heater 12 is controlled by a silicon controlled rectifier 44 which is fired at a variable instant in each pulse of rectified A.C. obtained from a mains A.C. source 33 and full-wave rectifier 40, the control electrode 48 of the rectifier 44 being supplied with firing pulses from an oscillator whose frequency varies with variations in the heater temperature to vary the instant at which rectifier 44 is fired and so maintain the temperature constant. As shown, a unijunction transistor 50 forms part of a relaxation oscillator circuit including another transistor 60 and members 62, 64, 66, the oscillator frequency being made independent of the frequency of the source 33 by means of the filter members 75, 76, 78, 80, 82 interposed between the rectifier 40 and the oscillator input. The oscillator frequency varies with the variation of the effective resistance of the transistor 60 to whose base is applied, through amplifying transistors 106, 116, 122, a voltage determined by temperature sensitive devices 30, 32 respectively positioned in contact with the heater 12 and external to the space heated thereby, Fig. 2 (not shown). Device 30 is a thermistor and device 32, which can be omitted if desired, may be a positive temperature coefficient resistor relatively insensitive compared with thermistor 30 or may be another thermistor connected between the base of transistor 106 and the resistor 104, the former embodiment being suitable when the device is positioned to detect sharp changes of temperature, e.g. in an outdoor location. Members 92, 94 prevent spurious firing of the rectifier 44. Transistors 60, 116 are temperature compensated by emitter resistances 128, 118. The choice of the circuit members around transistor 106 causes the thermistor 30 to overcompensate for temperature changes and provide the measure of temperature sensitivity necessary for control.

Filed: 1970-06-12
Abstract: 1309764 Electrolytic migration of sodium ions in semi-conductor INTERNATIONAL BUSINESS MACHINES CORP 12 June 1970 [18 June 1969 ] 28508/70 Heading C7B [Also in Divisions C1 and H1] A semi-conductor device is coated with a Si containing material (e.g. SiO 2 ) and Na ions contained therein are caused to migrate to the surface, which are removed. Migration may be caused by applying a thin film of metal (e.g. aluminium) to the surface and then applying a negative bias to the film, whilst heating, and the surface layer may be converted to phosphosilicate glass by treatment with P 2 O 5  before application of the film. Alternatively the device may be placed in a vacuum in close proximity to a filament which is heated to emit electrons. A voltage drop between the device and the filament causes the device to be bombarded and to aquire, at its surface, a negative charge, thus encouraging migration. The surface layer may be removed by sputtering, and a protective layer, e.g. silicon nitride, deposited by sputtering.

In making wire netting a plurality of wires are fed in parallel planes, each wire is bent into a zig-zag of such amplitude that when all the wires are arranged in a single plane they will not intersect but the bends on adjacent wires will abut and the wires are welded at the abutting bends. In one embodiment wires #, g, Figs. 1, 2, are fed into grooves e in slides d in front of drums a, b provided with teeth c in zig-zag formation. The drums are rotated and the slides are reciprocated to guide the wires around the teeth which latter form electrodes to weld the abutting bends at the points h. The finished netting leaves at i. The drums may be replaced by endless belts. In a further embodiment slides l, Fig. 4, carrying guiding and gripping elements m are arranged on the surface of a single rotating drum. The slides are biased to the position shown on the left-hand side so that the wires run on to the drum between the elements m. The slides are moved in the direction of the arrows x, x<SP>1</SP> by cam surfaces o and n to bend the wires which are welded by the elements m which form electrodes. After welding, the wires are returned to their initial position to allow the netting to run off the drum. Wires of open squares or rectangles are bent and welded on a similar apparatus. The guiding elements may be arranged on a pair of drums or on one or a pair of belts.
