Title: Process for the treatment of a textile yarn
IPC: D02G1/16
Filed: 1969-03-18
Abstract: A process for the manufacture of high-bulk textile yarns comprises passing a spun yarn containing shrinkable and relatively unshrinkable fibres under a tension less than 0.1 gram per denier through a turbulent fluid zone and also subjecting it to conditions which cause ithe shrinkable fibres to shrink. The shrinkage operation preferably takes place after the passage of the yarn through the turbulent fluid zone, and is effected by heat, e.g. steam treatment. The shrinkable fibres preferably shrink by at least 25%, advantageously at least 50%, of their length. The turbulent fluid is advantageously a cold inert gas. The yarn travels through a conduit 6 opening into a chamber 7, the compressed fluid being fed by means of a channel 9 into the chamber 7, the channel 9 meeting the chamber 7 at an acute angle with the forward direction of travel of the yarn 'so producing a turbulent fluid zone. The difference in shrinkage potential between the shrinkable and relatively unshrinkable fibres is at least 20%. In preferred embodiment, polyvinyl chloride fibres are used as the shrinkable fibres and polyacrylonitrile fibres as the unshrinkable fibres. The yarn produced has a high bulk and fluffy appearance.
Patent ES-364970-A1 (ES)
Title: Improvements in or relating to drilling methods and apparatus
IPC: E21B47/12
Filed: 1969-03-20
Abstract: The mechanical properties of rock are measured during a drilling operation by measuring the vibrations of the upper part of the drilling assembly. The vibrations are sensed by a strain gauge bridge circuit responsive to stresses at the top of the drilling assembly and by pick-ups responsive to the longitudinal or torsional acceleration of the top of the drilling assembly. Band pass filters 7, 8 pass components of the stress signal 5 and acceleration signal 6 at the frequency equal to the rotational speed of the drill multiplied by the number of operational elements on the tool. The acceleration signal passes through amplifier 11 and integrator 11a and is added to the stress signal in adding unit 12. The composite signal is amplified at 14, phase-shifted at 16, and supplied to one input each of a differential amplifier 18 and a phase comparator 28. Generator 4 generates an alternating voltage of amplitude proportional to the frequency, which is fed through adjustable gain amplifier 23, adjustable phaseshifter 30 and delay line 32 to be compared in amplitude and phase at 18, 28 respectively with the composite signal. The outputs of differential amplifier 18, integrated at 20, and of phase comparator 28 are used to control the settings of 23, 30 which settings at balance are evaluated at 37 and recorded at 38 as a function of drill depth. The drilling may be controlled in dependance on the rock characteristics, the rotational speed of the drill being varied to find the speed which gives the maximum vibration amplitude and the speed being maintained at the value to give this maximum amplitude.

Title: Apparatus and method for manufacturing spiral windings of electrode and separator strips for electrochemical generators
IPC: H01M10/28
Filed: 1969-12-17
Abstract: A method of making a coiled accumulator electrode includes stacking electrode and separator strips on an elongate guide 140, engaging one end of the strips with a mandrel 156, rotating the mandrel to coil the strips therearound and varying the position of the guide relative to the mandrel so that the portions of the strips in the guide are maintained substantially tangential to the portions of the strips coiled on the mandrel and so that there is no relative sliding movement between the strips and the guide. The mandrel is split diametrally and one half is withdrawn before the strip ends are offered up to it. A jet of air from a nozzle 160 wraps the end of the strips around the mandrel half, whereupon the other half is advanced to secure the strips. As winding proceeds, the guide 140, which is mounted on rollers 62, is advanced by drive rollers 63, 64 and pivots about a shaft 155 as the diameter of the coil increases. A jack 157 applies a compressive load on the coil. When coiling is completed, the coil is located in a cylindrical cavity formed by a member 158 in position 1581 and a recess at the end of the guide 140. The member 158 then advances with the guide to a work station, where, after the mandrel has been withdrawn, it is inserted in a metal casing. In an alternative embodiment, the guide instead of being pivoted, is lowered horizontally as the coil diameter increases so that the uncoiled portion of the strips is always tangential to the coiled portion, Fig. 2 (not shown). The stack of strips is held in the guide either by magnetic or vacuum means.

Title: Method of and apparatus for producing a vehicle movement control signal in response to sensing the direction of travel of a vehicle
IPC: B61L1/16
Filed: 1973-01-20
Abstract: A pair of tachometers are operatively engaged with the drive mechanism of a vehicle. The tachometers are aligned relative to one another such that if the vehicle is traveling in a forward direction the signal provided at the output of the first tachometer leads the signal provided at the output of the second tachometer by a first predetermined phase angle, and if the vehicle is traveling in the reverse direction, the signal output of the second tachometer leads the signal output of the first tachometer by a second predetermined phase angle. Apparatus is included for sensing the relative phase of the respective signals provided at the outputs of the tachometers. In response to sensing that the output signal of the first tachometer leads the output signal of the second tachometer by the first predetermined phase angle, a vehicle movement control signal is provided which informs the vehicle drive mechanism that it is safe for the vehicle to continue its movement. In the event the apparatus senses that the output signal of the second tachometer leads the output signal of the first tachometer by the second predetermined phase angle, the provision of the vehicle movement control signal is inhibited.
