Title: Improvements in velodynes
Inventor: MUDIE RONALD
IPC: G05B11/01
Filed: 1954-04-30
Abstract: 757,134. Electric analogue calculating systems. SERVOMEX CONTROLS, Ltd. March 15, 1955 [April 30, 1954], No. 12680/54. Class 37. [Also in Group XXXVII] A velodyne arrangement for producing a linear sweep of velocity or a linear sweep of voltage comprises a split-field motor M mechanically coupled to a generator G. A resistor R, a capacitor C, and the generator armature are connected between the positive and negative terminals of a source E of high-tension potential. The junction-point of the resistor and capacitor is connected to an input terminal of a highgain amplifier A, the other input terminal of which is connected to the negative terminal of the source. The motor split-field windings are supplied from the output circuit of the amplifier. The arrangement is such that the generated voltage across capacitor C is initially zero and rises linearly with time at a rate determined by the values of E, R and C. Furthermore, the instantaneous generator voltage is the integral with respect to time of the input voltage E, so that the number of revolutions measured on a counter is the second integral of the input voltage.

Title: Process and apparatus for twisting textile slivers
IPC: D01H7/92
Filed: 1962-04-03
Abstract: 933,367. Twist tubes. A. KRUSE. April 3, 1962 [April 4, 1961], No. 12816/62. Classes 120 (2) and 120 (3). A process for simultaneously consolidating and twisting fibre slivers comprises passing a sliver through a small rotating tube F, between pairs of rollers B, C and D, E, so that false twist is imparted by feelers H, attached to the end of the rotating tube F but alternately moved between position I in which the feelers twist the sliver and position II in which the feelers are out of contact with the sliver. The tube F is sufficiently wide and smooth that the tube itself does not twist the sliver. The feelers, preferably two or more in number, are moved, in Fig. 1, into the gripping position by a ring K, and returned by centrifugal force, the ring K being reciprocated by an eccentric drive. The ring may be replaced by a sleeve (Fig. 4, not shown) attached to the inner race of a ball bearing. In a further embodiment (Fig. 2, not shown) the feelers are centrally pivoted, being thrown into the gripping position by centrifugal force and being returned by an intermittently actuated electromagnet. The pivoted feelers may be replaced (Fig. 5) by spring loaded plungers forced into contact with the sliver by a sliding plate W reciprocated by suitable mechanism.

Title: Improvements in and relating to motion summation mechanism employing one-way driving gearing
IPC: G07F15/06
Filed: 1933-05-03
Abstract: 419,150. Adding rotary motions. FERRANTI, Ltd., and PRINCE, J., Hollinwood, Lancashire. May 2, 1933, Nos. 12955/33, 16392 /33, and 13239/34. [Class 80 (i).] Mechanism for adding together two motions, such as those obtained from an electricity consumption meter and a basic charge meter, comprises an overrunnable driving connection between one motion and a motion summation member and means serving automatically either to establish or to break momentary driving connection between the other motion and the motion summation member. In the form shown in Fig. 1, motion is produced in the shaft 3 from both the meter 15 and a basic charge motor 14. The meter rotates through reducing gearing a squared shaft 7 carrying a slidable worm 6, spring-pressed axially against a slidable but non-rotatable ring 8. The worm engages a worm-wheel 2 carrying a pawl 5 which engages a ratchet wheel 4 on the shaft 3. The motor 14 constantly rotates a wheel 12 carrying a stepped cam 13 engaging the ring 8, which is thus slid to the left and imparts a rotation to the worm wheel 2 additional to that produced by the rotation of the shaft 7 from the meter 15. When the step on the cam 13 reaches the step on the ring 8 the worm 6 is suddenly drawn back to the right, the pawl 5 sliding over the teeth of the ratchet wheel 4. The motion of the shaft 3 is transmitted to the planet-carrying arm 29 on the shaft 28, which carries the arm 27 operating the cut-off switch. The apparatus is reset by turning the coin-operated member 24, which rotates the shaft 28 backwards through the bevel gear 22 and simultaneously winds up a spring 19 connected through a friction clutch and a pinion 18 to the gear 17 driving the shaft 7, to provide energy for the switch-disengaging movement. In the form shown in Fig. 3, the motion of the basic charge motor 14 is communicated to the motion summation shaft 3 through a worm wheel 2 carrying a spring 30 engaging the teeth of a star-wheel 3<a>. The additional motion from the meter 15 is derived from gearwheels 36 frictionally mounted on pins on a disc 32 so as to engage a gear 38 on the shaft 3. The disc 32 tends to be rotated by a spring 39 wound up through gears 20<a>, 21, 22 from the coin-operated member 24, and is permitted to rotate at intervals by an escapement comprising a short worm 34 driven from the meter 15 and engaging pairs of teeth 33 at opposite sides of the disc 32. In the form shown in Fig. 4, the gear 52 is continuously rotated from the basic charge motor through a sleeve 48, spur gears 47, 46, helical gears 44, 40 and ratchet gear 42. The meter spindle 50 carries a cam 49 which moves the counter-shaft 45 longitudinally so as to give an additional rotation to the member 52, the shaft springing back under the action of a spring 57 when the step of the cam is passed.
