Title: False-twister
Inventor: BRINER EMIL
IPC: D02G1/04
Filed: 1983-12-21
Granted: 1986-07-10
Abstract: A false twist unit comprises a suction portion with a suction channel and with an expansion space connected at the throat portion or narrowest position of the suction channel, which expansion space is connected by means of an air connector or exit to a source of negative pressure. A throttle location connects the expansion space with a pneumatic twist imparting means. In the pneumatic false twist spinning process known from the German published Pat. No. 2,722,319 a sliver delivered from an exit roller pair of a drafting mechanism is forwarded through the suction channel in a predetermined direction and thereafter through the throttle location into the twist imparting means. The twist imparting means produces in the core of the yarn or thread a false twist which builds up in such yarn or thread towards the exit roller pair. The wrapping fibers required for the finished yarn or thread are sucked in as edge fibers through the suction channel simultaneously with the yarn core. By means of the expansion space the advantage is obtained that the air flow can be sucked away without substantial disturbance to the yarn travel path in a direction substantially at right angles to such yarn travel path.

Abstract: A logic system preferably for gallium arsenide integrated circuits uses dynamic pulsed logic gates which switch on each clock pulse, with the logical state of an output or data line being indicated by the phase of the pulsed output, which may be shifted or modulated with respect to a reference. An individual logic gate (1) has a first signal generator having a capacitor (30) which is either charged up or discharged during a set-up phase of a clock cycle, depending upon applied input logic signals. During a second, transmit phase of the clock signal, the signal developed on the capacitor is output from the gate. A second signal generator (112 - 131) is an inverting slave of the first, and outputs the inverse logic state during the succeeding set-up phase of the first generator. 
<??>With each gate switching on every clock period, all switching noise appearing in the ground or power supplies is at or above the clock frequency and can simply be filtered out with small chip capacitors, providing improvements in noise immunity. 
<??>The logic is preferably implemented in gallium arsenide metal oxide semiconductor technology, with the capacitors formed from reverse-biased Schottky diodes and all FET switches capacitively coupled and self biased.
