Title: Improvements relating to arc welding equipment
Inventor: NEEDHAM JAMES CHRISTOPHER
IPC: B23K9/073
Filed: 1950-08-11
Abstract: 705,164. Supply systems for welding arcs. BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION. Aug. 10, 1951 [Aug. 11, 1950; May. 3, 1951], Nos. 20032/50 and 10437/51. Class 38 (4) To improve the stability of an A.C. welding arc whilst allowing a reduction of open circuit voltage of the main current source, a switching device is effective, immediately the arc commences to extinguish, to connect to the arc an auxiliary low power source which then supplies the arc gap with voltage impulses to maintain ionization. The switching device may be responsive to voltage rise of the arc, to a marked increase of its resistance, or to the occurrence of zero current. In the arrangement shown in Fig. 1 a value amplifier 10, responsive to the voltage across an arc 1, 2 supplied from a main source WT, triggers a cold cathode thyratron 6 if the arc voltage rises and causes a condenser 3 to discharge into the arc and thus maintain it. The condenser is continuously charged over a resistor 5 from a battery 4 of, say, 450 volts. In modified arrangements the condenser may discharge in series with the main source, or the amplifier 10 may be dispensed with. Several other arrangements are described in which the condenser is coupled to the arc circuit by a transformer either for the purpose of matching the impedances of the two circuits, or for obtaining a high impulse voltage sufficient for the initial striking of the main arc. Fig. 9 shows one such arrangement in which the condenser 3 discharges through two transformers. Transformer ATI (and associated condenser 27) provides a short high voltage pulse over a spark gap 28 to ionize the welding gap 1, 2, this pulse being followed by a longer pulse of lower voltage (to maintain the ionization) by transformer AT and associated condenser 35.

Title: Improvements in or relating to electrical systems for the reception, storage, processing and retransmission of data
Inventor: BELL HAMISH VERNON
IPC: H04L12/54
Filed: 1965-05-13
Abstract: 1,101,935. Telegraphy. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 6 May, 1966 [13 May, 1965], No. 20177/65. Heading H4P. A telegraph exchange comprises a number of data processors among which the incoming and outgoing lines are shared. If a fault is found in a processor the lines connected to it are shared among the remaining processors. Each input line feeds data to a corresponding input unit which removes the Start and Stop bits, generates a parity bit, and stores the resultant signal in parallel form. When a character is so stored a " ready " signal from the input unit causes the processor to address that unit and store the character read from it. In the embodiment described, characters from up to three input units may be transferred simultaneously. The remaining input units associated with this processor are scanned in groups of three. The processor's programme is so arranged that initiation of the input of characters takes place once per character, whatever the stage reached in the input routine. The processor assembles the characters from each line into blocks. When a block is complete it is transferred to a store common to all the processors, an address in this store having been allocated on detection of the Start-ofmessage signal. The processor generates a message number and channel identity, and compares these with the corresponding data received from the line. If they differ an alarm is actuated. The routing and priority information in the message is placed in section of a queue store, forming part of the common store and associated with the destination of the message. When an output line is free the processor to which it is connected inspects the corresponding queue store section and reads from it the message block of highest priority for that line. The processor passes the characters to the output units, which are scanned in a manner similar to the scan of the input units. Start and Stop bits are added, and the characters sent in serial-bit form to the line.

Abstract: 1409392 Automatic control of current and voltage AUTOMATIC POWER Inc 1 May 1973 [14 June 1972] 20594/73 Heading G3R The load on a generator charging a battery is maintained constant by controlling a variable shunt connected across the generator in dependence on a sensed condition of the battery. As shown, a permanent magnet generator 14 driven by a diesel engine 15 charges a battery 10 over a transformer 16, rectifier 17 and filter 18. A shunt is formed by a resistor 19 in series with a thyristor switch 20 across the generator output terminals. In operation, a circuit 21 senses the battery voltage and fires the switch 20 periodically to maintain the generator load constant. The sensing circuit, Fig. 5 (not shown), may include a differential amplifier with a Zener diode reference controlling the charging of a capacitor which produces a firing pulse when a uni-junction transistor breaks down. The circuit also receives an input direct from the generator so that the pulse corresponds to a firing angle related to the sensed battery voltage, the shunt resistance 19 being connected in circuit later in each half cycle if the battery charge is low or a high current is being supplied to a load L. The action of the circuit is such as to maintain the current and voltage developed by the generator within a narrow range of values.

Abstract: 842,573. Photo-electric printing control. RANK CINTEL Ltd. July 1, 1958 [July 1, 1957], No. 20669/57. Class 40(3). [Also in Group XX] The invention relates to photographic printing apparatus of the type in which a scanning spot of light from a cathode ray tube I passes through the negative 4 and printing paper 5 and is received on a photo-electric cell 6, the output of which is fed back through an amplifier to control the spot brightness. According to the invention, in order that the scanning pattern shall not be precisely repeated, the travel of the spot is controlled by two oscillators 14, 15 each controlling the current in a pair of scanning coils, the arrangement being that the output frequency from oscillator 14 is controlled at 2 k.c/sec. while that from oscillator 15 is caused to vary through a range, from 1.9 to 2.1 k.c/sec. The variation may be produced by a reactance valve in the oscillator fed with the increasing voltage of a timing capacitor which suppresses the cathode ray tube beam after a predetermined time. Specification 833,747 is referred to.
