Abstract: 1,266,450. Measuring twist in yarns. G. A. CARRUTHERS. 11 May, 1970 [9 May, 1969], No. 23642/69. Heading D1F. An instrument for measuring the degree of twist being imparted to a continuous travelling yarn 10 by an apparatus e.g. a falsetwist spindle 12, causing the yarn to move both longitudinally and rotationally, comprises a sensing member 14 pivoted for free movement about an axis normal to, but spaced from, the yarn path, which member 14 has a part 14a engaging the yarn surface whereby pivoting of the member 14 to assume an angular disposition indicates the amount of twist being imparted. The amount of twist may be indicated on a scale 18. In a preferred embodiment, two photoelectric cells 20 are positioned in the angular path of the member 14 so that if the member 14 moves outside these cells, signals are sent to the motor controlling the speed of the twisting apparatus whereby the twist imparted to the yarn is maintained within specified limits.

Abstract: 1289679 Sonar systems; pulse circuits CCI AEROSPACE CORP 9 April 1970 [10 April 1969] 16939/70 Headings H3P and H4D In a pulse Doppler marine sonar system, the width and spacing of the transmitted pulses is varied from pulse to pulse to avoid the receiving apparatus locking on to strong frequency sidebands of the transmitted carrier frequency, which sidebands could arise if the pulse transmission were uniform. In the Fig. 2 embodiment for determining the velocity of a marine craft, transducers 12, 14, 16, 18 on the craft provide directional downward beams inclined in the aft, starboard, port and fore directions respectively. A master oscillator signal from 30 is gated at 20 by pulse generator 32 to provide a non-uniform pulse train for energizing the transducers via duplexers 22, 24, 26, 28. Received echo signals are fed to separate but similar processing channels via the duplexers. Thus the transducer 18 echo signals are amplified at 34, 38 and their carrier frequency is tracked at 42 by a phase-locked loop system. Gate 36 and gain control 40 provide blanking of received signals during the acoustic pulse duration, plus subsequent timevaried gain and AGC. Automatic acquisition circuit 44 ensures that tracker 42 follows the carrier frequency of echo signals from amplifier 38 and " holds " that frequency when no echo signal is being received. Demodulator 52 compares the tracker frequency with the master oscillator frequency to provide Doppler shift signals which are processed at 58, 66 together with the demodulator signals for the other channels, giving signals representing four velocities which are displayed at 68, 70, 72, 74. The width and space varied pulse generator 32 comprises (Fig. 4) an AND gate 90 receiving uniform pulses A from generator 88 and, after frequency-halving, from divider 92. Gate 90 effectively eliminates alternate ones of the uniform pulses, and its output C forms one input to OR gate 100. Divider 92 output is delayed at 94 then frequency-halved at 96 for triggering one-shot 98 whose output is the second input to OR gate 100. Gate 100 output, F, is thus a pulse train in which alternate ones of the eliminated uniform pulses have been replaced by the one-shot pulses E.

The cap 13 may be of silver, copper, gold or nickel, and may be spot welded at points 23 to the face 24. The alloy may be a copper/ silver eutectic and may be applied to faces 12 and 24 of the mass 9. The mass may be of tungsten/silver, and may be treated by etching to remove the tungsten from the faces, hence forming a silver "sponge" prior to coating with the alloy. Alternatively the mass may be of molybdenum, which is nickel plated and sintered, and further nickel or gold plated prior to alloy coating. The face 12 may not be coated or have the coating removed therefrom in order that the cap 13 and face 12 may move relatively to allow for differential thermal expansion therebetween. The contact shown may be suitable for a diode. A contact for a thyristor including an axial bore to insulating accommodate a contact to the gate region is also disclosed.
