Abstract: A method of digital control of m-phase thyristor-pulse converters, in which the duration of the conductive state of the thyristors of each phase of an m-phase thyristor-pulse converter is changed by sending time-shifted and time-constant pulse trains successively from each control channel to the thyristors of respective phases with simultaneous shift of the onset of operation of the thyristors of each phase by (1/m) period of switching the thyristors. Successive connection of each control channel to a respective phase is effected upon achieving the maximum value of the control zone of each control channel. The apparatus for carrying out the proposed method includes a master oscillator connected to a clock counter whose outputs are connected to the inputs of a decoder for decoding the time-constant pulse trains and to the logic inputs of "m" decoders for decoding the time-shifted pulse trains.

Abstract: A knitting machine arrangement and a method of knitting on the same are described which utilize a pair of stacked pattern wheels at each knitting station of a circular knitting machine. By alternating high and low butt knitting needle groups in successive slots of one portion of the cylinder, a singular pattern or design can be knitted by inserting appropriate jacks in the upper and lower pattern wheels which engage the associated needle groups. When the order of the high butt and low butt needles is reversed on another portion of the cylinder, alternate slots and, therefore, jacks of the pattern wheels are engaged and these may produce a different pattern or design. By dividing patterns between the upper and lower pattern wheels at each station, desired effects, such as spotting, design or pattern enlargement may be achieved by selectively placing needle groups about the periphery of the cylinder.
