Title: Control device for equipment for winding yarn into cops
IPC: D01H1/36
Filed: 1973-12-19
Abstract: 1417268 Yarn traverse means FRATELLI MARZOLI & C SpA 19 Dec 1973 [29 Dec 1972 10 Aug 1973] 58803/73 Heading D1J A yarn traverse means Fig. 2 has a support 14 carrying two opposing and adjustably positioned strikers 29, 35; a control member 49 disposed between the strikers and serving by its engagement with each striker in turn to control the reversal of an actuator 10, Fig. 1, causing the yarn traverse motion, the control member 49 or the support 14 being linked by means 13 to the actuator 10 to cause relative motion between the strikers 29, 35 and the control member 49 in a first direction, horizontal in Figs. 1 and 2; and drive means 44 for moving the control member 49 with respect to the support 14 in a second direction orthogonal to the first, vertical in Figs. 1 and 2, to vary the zone in which the control member 49 engages the strikers 29, 35. The operation of the device of Figs. 1 and 2 is as follows. When the piston of cylinder 10 is being withdrawn it moves the support 14 to the left until a lever 50 of a microswitch of the control member 49 is in contact with the striker rod 29. The switch then causes a valve 52 to connect a pressure line 56 to a line 53 of the cylinder 10; and a drain line 82 to a line 54 of the cylinder 10. A pump 55 then feeds oil under pressure via line 53 into the cylinder 10 to move the rod 11, tie bar 12 and support 14 towards the right until the lever 50 touches the striker 35. At this instant the microswitch is again actuated and through line 51 operates the valve 52 so that line 54 is connected to the line 56; and the line 53 is connected to drain 82. Oil under pressure is then fed into cylinder 10 through line 54 until the lever 50 again comes into contact with the striker 29 and the cycle then begins again. A drive unit 48 moves a platform 40 carrying the control member 49 vertically so that the zone of the strikers 29 and 35 against which the lever 50 engages varies continuously. By varying the angle between the strikers 29, 35 and the speed of the motor 48, the taper at the ends of the winding can be adjusted. In this embodiment the traverse length is slowly reduced during package build up. To produce a traverse motion as illustrated in Fig. 10 the apparatus may be modified as in Fig. 8. In Fig. 8 the platform 40 carrying the control member 49 rises and falls continuously between a pair of microswitches 124, 125; the microswitches 124, 125 controlling the operation of the drive unit 48. In addition, the rod 121 on which the microswitches 124, 125 are mounted is given a small reciprocating motion by means of a cam 127. Variable oil flow. The lower side of the slider 14 carries a blade 57 the inclination of which can be varied by means of knobs 58. The blade 57 is in contact with the wheel 60 of a device 61 secured to a stationary part 19 of the apparatus, the device 61 varying the flow of oil in the line 56 in accordance with the inclination of the blade 57 by acting in known manner on a variable flow pump by way of line 62.

Abstract: 1367586 A/D converter W KRAUT [trading as BIZERBA-WERKE WILHELM KRAUT KG] E SCHULTE and O PICHL [trading as DATRON - ELECTRONIC PICHL & SCHULTE KG] 21 Dec 1972 [23 Dec 1971] 59035/72 Heading G4H A digital voltmeter comprises a constant negative voltage source 5 supplying an integrator 1, a reference voltage source 4, and a comparator 3 for comparing the output voltage of the integrator at point C with a voltage at point A which may either be the reference voltage or an unknown voltage U x , the output of the comparator being input to a control unit 8 which controls a counter 5 and a store 7 and the several switches shown. In operation, the output of the integrator is first pushed to a positive maximum by closure of switch S5 and the counter is set at +n max . Switch S4 is then closed together with S2, and switch S5 is opened and the voltage at C is compared at 3 with a voltage (- U ref ), and when the voltage at point B equals zero the controller 8 causes pulses from a generator 6 to decrement counter 5 and also closes switch S3 and opens S2 whereby the unknown voltage U x  is compared with the ramp output of the integrator. If U x  is <0, equality at point B occurs when the voltage at point C is >0, and this equality causes the controller 8 to cause the count at 5 to be stored at 7, which count is a measure of the voltage U x . If U x  > 0 the integrator voltage falls to zero as does the count at 5, and at this point the controller causes, by means of a switch S8, the counter to count upwards. The integrator output at C continues to increase in a negative sense and when the voltage at B is equal to zero the stored 7 is activated as above, the position of the switch 8 being indicative of the sign of U x . The counter is counted up to + n max  again and the voltage at C is allowed to fall to a minimum which should be equal to +U ref . At this point the switch S1 is closed and the comparison made. If any deviation is detected the constant voltage value at 2 is amended via switches S6, S7 to correct this.

Patent GB-753258-A (GB)
Abstract: 753,258. Gyroscopic apparatus. NAAMLOOZE VENNOOTSCHAP HOLLANDSE SIGNAALAPPARATEN. March 31, 1954 [April 2, 1953], No. 9452/54..Class 97 (3). Relates to gyroscopic mechanisms comprising a rotor rotatable in a housing, a gimbal ring supporting the housing about a first axis transverse to the rotor axis, a pair of supports on which the gimbal ring is mounted for rotation about a second axis transverse to the first axis and which are fixed to a ship or other object, and flexible electric conductors to supply current to electric devices on the gimbal ring and/or the housing, which conductors are supported at two spaced points, one on a support and one on the gimbal ring and, when the conductors extend to the housing, at two other fixed points, one on the gimbal ring and one on the housing, the mechanism being adjustable about at least one of the axes to maintain a fixed relation with the direction of gravity. In such mechanism, a pendulum subject to gravity and an arm connected thereto are mounted for rotation about axes coincident or parallel to an axis of adjustment, and the arm carries the flexible conductors at a point intermediate two supporting points, whereby the pendulum causes the arm to influence the conductors so that when the mechanism is adjusted in accordance with the direction of gravity the conductors exert substantially less torque on the gyroscope housing than would be the case in the absence of the pendulum. The conductors may be rigidly supported by the arm, and the arm and pendulum may be combined to form a single part. As shown in Fig. 1, the gyro casing 101 is pivoted in a gimbal ring 103, which is mounted on a shaft 104 mounted in ball-bearings in supports 105, 106. Support 106 has a. bored stub 113 supporting a pendulum 111 and the end bearing 114 of shaft 104, these parts being shown in exploded view. Bearing 114 fits in the bore of stub 113, which may be eccentrically disposed, and the pendulum has a bearing 112 fitting over the stub. The conductors 109, which carry current to the rotor driving motor and the torque motor 116, are clamped at 107 to support 106 and at 108 to the gimbal 103 and between these supports pass through a ring 110 on the pendulum. Alternative arrangements are described in which an arm separate from the pendulum supports the conductors; the arm and pendulum may be some distance apart and connected by a flat link or may be close together and connected by a pin and slot. The arm is arranged to move further than the pendulum, to compensate for the torque exerted on the pendulum by the conductors.
