Title: Communication systems
IPC: H04B14/02
Filed: 1972-01-11
Abstract: 1377583 Multiplex pulse signalling; synchronizing BRITISH AIRCRAFT CORP Ltd 8 Jan 1973 [11 Jan 1972] 1294/72 Headings H4L and H4P A transmitter includes means for generating successive frames within which data is transmitted, each frame including an initial delay period during which data is not transmitted and which is used for synchronizing, and means for jittering the start of successive frames of said signals so that the start of each period within which data is transmitted is delayed by a random amount. Each frame extends over a fixed time interval and may carry a predetermined number of pulses, the spacing of the pulses being varied to provide a coded signal and the system is stated to reduce crosstalk. The jittering is controlled by a pseudo-random number generator, Fig. 1 (not shown), which includes a shift register connected to receive pulses from a free running oscillator via a gate which is enabled periodically to pass a number of pulses which varies with the changing phase of the oscillator. This number controls the pseudo-random number generator whose resulting output is counted down to produce a start pulse for the next frame. As described, Fig. 4, each frame includes the start pulse P1 defining the start of the sync. delay period, d 1  representing the random delay, a second pulse P2 defining the end of the sync. delay period d 2  which is fixed and a final pulse P3, the interval d 3  between pulses P2, P3 being varied in accordance with the data. The start pulse P1 resets a counter C1, Fig. 3, to zero, is supplied to the output and sets a counter C2 to a predetermined number corresponding to the required sync. delay. The gates connected to counter C1 produce binary 1 at output Y whereby clock pulses cause counter C2 to count down to zero and via NAND gate G14 and generator X2 to produce pulse P2 defining the end of the sync. period. Pulse P2 also clocks the input information, in the form of a binary number representing the desired interval d 3 , into a counter C3, and adds one  to the pulse number counter C1. This produces binary 0 at output Y and binary 1 at output Z whereby clock pulses cause counter C3 to count down to zero, when via NAND gate G15 a generator X3 produces pulse P3 which is fed to the output and to counter C1. This causes output R to block the entry of any further pulses into C1 which awaits the next random start pulse to repeat the sequence. Fig. 3 shows only one channel but other channels may be added, each channel having its own random number generator and counter for jittering the start of the sync. period.

Abstract: <PICT:0584824/IV/1> <PICT:0584824/IV/2> A machine for the continuous manufacture of artificial filaments or threads which is economical in the utilization of space, liquids and labour, has two working faces throughout all sections thereof, such that multiple filament threads formed in the spinning bath on one side of the machine pass above the bath through one of a plurality of substantially parallel horizontal paths across the central plane of the machine at an acute angle thereto, then descend substantially vertically on the other side of the machine to the liquid treating, drying and collecting devices arranged in substantially direct vertical superposition.  Similarly, filaments formed in the spinning bath on the other side of the machine move in horizontal paths which alternate with, are substantially parallel to and lie in approximately the same plane as that which contains the paths of the filaments proceeding from the first side and then similarly descend vertically to the after-treating sections on the first side of the machine.  Referring to Figs. 1 and 3, the spinning deck A comprises two spinning troughs 2, each of which extends the length of the machine and in each of which a plurality of spinnerets 4 are situated.  The filaments leave the spinnerets 4 on one side of the machine, pass through the spinning bath at an acute angle to the length of the machine, proceed around the guides 5 and then around godets 7 and canted guides 8. The filaments then proceed to the other side of the machine and are passed around godets 9 and canted guides 9a from which they descend to deck B where they are treated with different liquids on a plurality of thread advancing, thread storage devices 12a, 12b, 12n. The threads are then passed to deck C where they are dried as they proceed around steam-heated drums 13 and canted idlers 14, being finally collected on any device such as a ring twister 15. By driving godets 9 at higher speed than godets 7, the threads may be stretched, and in their travel therebetween may pass through troughs 20 containing plasticising liquid.
