Abstract: 1,097,113. Electric correspondence control systems. OILGEAR CO. Dec. 21, 1965, No. 54080/65. Heading G1N. The tension on a strip of material being wound on to a roll is varied in accordance with the diameter of the roll, measured electrically. As shown (Fig. 1), a winder roll 1 for strip 2 is driven by an hydraulic motor 3 and pump 4. The outer diameter of the roll 1 is sensed by a feeler coupled by a rack and pinion 27 to the sliders 29, 30 of two A. C. -fed potentiometers 23, 24, the former producing a linearly-variable signal and the latter a square-law signal, which are combined in amplifier 22 to energize a torque motor 21 controlling through relief valve 7 the pressure in the hydraulic drive system, and hence the tension produced by motor 3, which is thus varied linearly with respect to the roll diameter.

The output from multi-plexer 60 is fed via line 62 to a second input of assignment switching modules 35 and thence over line 63 to demultiplexer 65 in the remote controlled apparatus. Each of the outputs of demulti-plexer 65, comprising a zero output or a train of pulses dependent upon the position of the corresponding switch 61 &c., is coupled to a corresponding monostable multi-vibrator 66 which stays in its triggered state so long as pulses are received, thereby producing a corresponding D.C. control output. Alternatively, a plurality of digital control switches 71 relating to mutually exclusive control functions may be connected via encoder 70 to multi-plexer 72, the output of which is directed to assignment switching module 35 and thence to demulti-plexer 73, which has coupled to each of its four outputs a separate monostable multi-vibrator included in module 74. The outputs from the monostable multi-vibrators are supplied to a decoder circuit 75 to obtain the plurality of mutually exclusive digital output control functions. Tally control. Monitor signals emanating from the remote location are applied to multi-plexer 80 and the multi-plexed signals thence over line 82 to assignment switching modules 83 which are coupled via line 84 to demulti-plexer 85. Each output of demulti-plexer 85 is coupled to a corresponding monostable multi-vibrator 86: when a pulse train is applied to it, this remains in its triggered state and biases a corresponding transistor 88 conductive, thereby energizing the corresponding indicator lamp 90. The sensitivity of the arrangement is increased by means of a resistor 89 which passes a standing bias current through lamp 90. Assignment switching modules.

When the lamp strikes the reduction in the voltage vetween terminals 7, 8 prevents further oscillation of the transistor circuit. The transformer windings are wound on a ferrite core 23 and the resistor 18 or 19 may be replaced by a positive or negative temperature coefficient resistor respectively to prevent an excessive duration of attempted starting of, for example, a defective lamp.

Abstract: 1331614 Mixed fibre yarn COMPTOIR INDUSTRIEL ET COMMERCIAL DES TEXTILES DU NORD "COCITEX" 4 Dec 1970 [24 June 1970] 57774/70 Heading D1W A method of manufacturing a composite knitting yarn comprises providing a hard natural fibre yarn (e.g. linen, jute, ramie and sisal) having an initial twist and a synthetic fibre yarn and winding one yarn around the other. In a preferred embodiment, a core thread 3 of untwisted continuous synthetic fibres is passed through a spindle 4 which rotates with a bobbin 5 containing twisted hard natural fibre yarn. The hard natural fibre yarn 6 is unwound from the bobbin 5 and winds around the core thread 3 in turns 7 such that no twist remains in the yarn 6. The composite yarn 2 is wound on a bobbin 1. In a further embodiment, a hard natural fibre yarn and a synthetic fibre yarn having the same amount and the same direction of twist are wound together in side-by-side relation on a bobbin. The yarns are then untwisted so that zero twist is obtained for each and they wind around each other. In a still further embodiment, a twisted hard natural fibre yarn is used as the core thread and a synthetic fibre yarn is wound thereabout. When a twisted synthetic fibre yarn is used, the twist may be thermally set e.g. through vapourisation. The composite yarn is particularly suitable for knitting processes.
