Title: Method of controlling the operating conditions of an appara tus for plasma-arc treatment of articles and ap apparatus for  plasma-arc treatment
IPC: B23K10/00
Filed: 1971-07-29
Abstract: 1331139 Welding by fusion I S SHAPIRO L M PERSITS M V TKACHEV and L E LINETSKY 29 July 1971 35613/71 Heading B3R [Also in Division H2] In a method of controlling a plasma-arc device 1 for cutting or welding, the voltage between the cathode 2 and the gas supply nozzle 3 is sensed to enable the increase of the arc current to be discontinued when an abrupt voltage increase is detected. The voltage is sensed by a circuit 8 comprising a filter 24 and a threshold circuit 25, the output of which is connected to a current supply source 7 for the plasma-arc device. The source 7 comprises a d.c. generator 11, a circuit 12 for increasing the supply current, a circuit 14 for decreasing the supply current and a counter 16. When the arc current exceeds a certain value the circuit 8 supplies a pulse to a circuit 13 to switch off the circuit 12 and to the counter 16 which enables the circuit 14 to reduce the arc current. Other pulses may subsequently be received by the counter, for example if the nozzle contacts the article 4 or if the gas supply to the nozzle is reduced, each pulse causing a successive decrease in the arc current. When the counter is full it operates a unit 15 to disconnect the generator 11. The sensing of the abrupt voltage increase which occurs when the arc shorts across to the nozzle enables this shorting to be stopped by reducing the arc current before damage to the nozzle occurs. The cathode is made of lanthanized tungsten and the copper nozzle is water-cooled. In a modification, the source 7 includes a D.C. and a pulsed-current generator connected in parallel and a two-position switch which selectively enables either one of the generators to provide the bulk of the arc current.

The spikes or needles 7 are arranged in rows extending longitudinally of the drum, the spikes or needles of successive rows being offset longitudinally of the drum. The tow may be crimped before or after the action of the stripping drum, e.g. by gear crimpers or stuffer box crimper.

Title: Apparatus for clocking digital data
IPC: H04L7/033
Filed: 1970-08-18
Abstract: 1355495 Digital transmission; synchronizing A C COSSOR Ltd 18 Aug 1971 [18 Aug 1970] 39797/70 Heading H4P To reconcile the phase of clock pulses with that of input data, a number of phase displaced clock synchronous wave forms are generated, one of which is selected nearest to the phase of input data. Such arrangement is particularly suitable for equipment having a delay line the characteristics of which may change with time and/or temperature. The arrangement may be applied to various types of data modulation, i.e. NRZ, RZ, bipolar or phase reversal. The input data clocked by a timing system 18 is passed through a delay line 12 and buffer stage 20 which may be a limiting amplifier or an amplifier followed by a Schmidt trigger circuit, the output being clocked to a flip-flop 22, e.g. D type before entering a utilization apparatus 16. If the output 28 of system 18 is fixed and passed directly to a flip-flop 22, while some tolerance in the instance of arrival between these pulses and those from delay line 12 is permissible, at some point errors will occur. This system is known in the art. The disclosure resides in the provision of a number of phase displaced pulse trains synchronized with timing system 18, an appropriate train being selected by a decoder 48 and passed by line 26 to flip-flop 22. Selection is determined by a differentiator 36 which is sensitive to either negative or positive going edges from buffer 20 and produces negative going spikes at its output which are applied to an R-S flip-flop formed by gates 38, 40 also receiving pulses 28, the output being passed through an AND gate 46 enabled only when R-S is reset, thus after the reference pulse has finished a counter 44 will be pulsed through its states starting from zero which will continue until a spike from differentiator 36 resets R-S which locks the clockpulses to the counter thus the count is indicative of the interval between the back edge of the reference pulse and the next positive or negative data edge respectively. The count is recognized by decoder 48 and the appropriate input from 18 is selected and routed to flip-flop 22. Differentiator 36 may be omitted but the amount of compensation possible will be reduced. As the timing of flip-flop 22 is arbitrary with reference to the clock pulses in the block 16, a second flip-flop 32 may be inserted and receives a signal of constant phase displacement from system 18. As the short term stability of a delay line is normally good, reference pulses may be applied with relative infrequency. A simpler arrangement is described with reference to Fig. 3 (not shown). Data is circulated round a delay line twice i.e. incoming bits are interleaved with bits circulating a second time and split at the output of the line by two flip-flops, which are clocked with different pulses; a compensation circuit may be adapted to this type of configuration. This employs a third flip-flop (52) and a switch (54) which diverts alternate ones of double rate pulses to flip-flop (52) and the other alternate ones to flipflop 22.
