Abstract: 939,168. Impedance discontinuity locating. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. Dec. 22, 1960 [Dec. 28, 1959], No. 44057/60. Class 40 (7). In an arrangement for determining the position and extent of variations in the characteristic impedance of a cable P (Fig. 2), the latter, terminated by its nominal characteristic impedance Zo, is connected in one arm of a bridge circuit including a balancing arm R 1 , R 2 , C 1 , C 2 , C 3 , a rectangular wave pulse generator G and an impedance Z equal to that of the measuring instrument specifically, an oscilloscope connected between points A and E. Fig. 3c, shows a typical oscilloscope trace representing multiple points of variations of Zo and by suitably calibrating the oscilloscope (in terms of R 1 ) and knowing the propagation time in the cable and the horizontal scanning velocity of the oscilloscope the magnitude and extent of the variations may be deduced. A knowledge of the latter together with a knowledge of the near-end and far-end cross-talk (e.g. between the two pairs when the cable comprises a quad the measurements being made on standard cable lengths at the factory) enables optimum use to be made of the different lengths when they are jointed together to form a complete cable. An arrangement for measuring the cross-talk which involves supplying rectangular pulses to one pair of a quad and observing on an oscilloscope the waveform induced in the other pair is described with reference to Fig. 4 (not shown). To facilitate copying such waveform (by drawing on a sheet of paper) the oscilloscope screen is reflected by a mirror on to a semi-transparent coloured sheet through which the observer can also view the paper on which the copy is to be produced (Fig. 5, not shown).

A proportion of the fibres have non-uniformly, partially, and/or undrawn portions along the length of each fibre, the birefringence of the fibre varying by at least 25 X 10<SP>-3</SP>. At least a proportion of the fibres are made from undrawn polyethylene terephthalate or stereo-specific polypropylene having birefringenres up to 0.16 or 0.003. The material may be made by cutting the undrawn filaments, at least a proportion of which have birefringence up to 0.005, partially elongating the fibres to at least twice their length at a temperature between -10‹ C. and 35‹ C. so that a proportion of the fibres are drawn intermittently and non-uniformly resulting in the specified birefringence variation e.g. by garnetting and carding, and then matting the resultant batt or web e.g. by needle punching. The material may be consolidated by a heat treatment e.g. steaming, which causes high shrinkage without fusing the fibres, and/or by compression e.g. between the platens of an hydraulic press.

Class 120(3) Sliver coiling apparatus of the type in which coiled sliver is delivered into any one of a number of cans without interruption of the delivery when the sliver is diverted from a full can to an empty can, comprises mountings 19 for at least two cans; a separate coiler-head assembly 16, 17 or 18 above each mounting; a sliver delivery unit 21; a means for shifting the unit 21 to co-operate with any one of the assemblies 16, 17, 18 so that sliver received thereby will be delivered into the can associated therewith. The mountings 19 are driven from the roller 13 through linkage 131, 231, 23, 193 and an endless chain 191 and the tube-wheels of the assemblies 16, 17, 18 are driven through gears 161, 171, 181, 26, 25, 24, 232, the 'latter being secured to the shaft 23. The sliver 15 passes around a guide 27, through a trumpet 217 and through delivery rollers mounted on a bracket 213. The bracket 213 carries rollers (not shown) which run on an arcuate track 214 and has two detents (also not shown) mounted thereon. The detents are co-operable with endless chains 28, 29 which rotate in opposite directions and are trained around the outer periphery of the track 214. When the first-can is full, apparatus (not shown) for measuring the length of sliver delivered into the can energizes a solenoid 215 on the bracket 213 to cause the associated detent to engage the chain 29. The unit 21 moves to the second can, a switch is tripped to disengage the detent and the unit is arrested by a stop 31. When this can is full the stop 31 is disengaged, the solenoid 215 energized and the unit 21 moves to engage the stop 30. After the third can is full the unit 21 is returned by the operation of a solenoid 216 causing the associated detent to engage the chain 28. The invention may also be applied to coiling apparatus in which the cans are either stationary or subjected to a processional motion.
