Abstract: 1393368 Measuring rotation of a falsetwist spindle D W AUCKLAND and N P LUTTE 30 Oct 1972 [6 Nov 1971 5 Feb 1972] 51681/71 and 5445/72 Headings DID and D1F [Also in Division G1] A yarn crimping machine in which a hollow false-twist spindle 10 is held, against one or more driving members 15 to be driven thereby, by a permanent magnet 16, is characterised in that means are provided for measuring the speed of rotation of the spindle, the means including a sensing coil 25 so disposed, relative to the magnet 16 and to surface irregularities e.g. threading-up apertures, transverse peg ends, in the spindle, that rotation of the spindle produces electrically- or electronically-countable pulses in the coil. The pulses are produced due to the change in magnetic flux owing to the presence of the irregularities. The magnet 16 is C-shaped in side elevation and the coil 25 is disposed to project into the gap between the poles 17, 18. Cutaway portions 20 are provided in the magnet to accommodate the spindle. In a preferred embodiment, the drive means 15 comprise upper and lower flanges 13, 14 engaging axial extensions 11, 12 of the spindle. Alternatively, the drive means comprises a grooved disc engaging a flanged portion on the spindle. In said alternative embodiment, the magnet is shaped to provide axially spaced poles, one on either side of the driving disc, the sensing coil being mounted on one of the poles. It is preferred that a visual indication is given of the speed of rotation of the spindle.

Abstract: 1,103,716. Converting circuits, protective arrangements, control of D.C. motors. W. J. BROWN. 11 Feb., 1966 [19 Feb., 1965], No. 6141/66. Headings H2F, H2J and H2K. [Also in Division G3] In a control circuit for a dynamo-electric machine the current supply to the machine is controlled by the current flowing through a free-wheel diode connected across it. In one embodiment, Fig. 12, current through free-wheel diode 311 and the voltage from a manual speed control 602 are fed to a magnetic amplifiers 1106 which generates the firing pulses for the SCR 307. Any increase in the load on a series wound motor 501 varies the current through diode 311 and increases the firing angle of the SCR to compensate for this increased load requirement. To provide overload protection, the current through the diode 311 is fed to the heater 902 of a thermal switch so that an excess current existing for a predetermined time opens contacts 903 to disconnect the supply to the motor, a resistor 1001 and indicator 1003 providing a current path to maintain the contacts open. The current through the diode 311 is higher at low motor speeds, so that the circuit will trip at a lower motor current at low speed, than at high speed. In a modification. Fig. 14 (not shown), the trip circuit shorts out the trigger pulse circuit to the SCR to prevent it firing. Modifications of the control circuit are also described in which the control of the free-wheel diode only becomes effective above a threshold level determined by a Zener diode, Fig. 7 (not shown), or a bias circuit, Fig. 8 (not shown). The overload cut-out circuits may also be employed without the control circuts, Figs. 9, 10, 11 (not shown).

R÷ntgen-ray and like apparatus.-Consits of a stationary frame to which is pivoted a table for the patient, an X-ray tube box being carried by the table. Fig. 2 shows a plan of the apparatus and Fig. 3 perspective view. The frame con sists of two side parts 6 - - 8 and 10 - - 13 re spectively, connected together by cross-bars 2 14, 15 so as to leave open ends. The bar 10 is longer than the bar 6. Upon the cross-bar 2. the table 1 is pivoted and is fixed in position by a notched quadrant 21. The tube box 31 slides laterally on cross-bars 30 of a frame, which itsel slides longitudinally on bars 26 of the table. The frame is connected to an adjustably weighted sliding counterweight 50 by cords 51 running over pulleys 52, 53. When the table is horizontal, the counterweight does not move; but when the table is tilted, the counterweight slides down against a stop on the cord and so follows the movement o: the tube box. The box carries terminals 83, 84 connected by self-winding conductors 82 to posts 80, 81 on the table, and these posts carry fingers 92, 93 for the leads 90, 91. The box also carries a sleeve 85 with a pivotally-mounted arm 86 electrically connected to a chemical chamber on the X-ray tube, stated to be for adjusting the vacuum. The arm 86 is operated by a cord 87. Above the box are two pairs of diaphragms, of which one pair only 112. 113 is shown. These are worked by links, a connecting-rod 120, and a handle at 122. The other pair below is worked similarly by a link 121 and a handle at 123. These handies may he coupled together by a pin on the piece 126. The bar 41 acts as a handle for adjusting the box. which is clamped when adjusted by a handle 40, which thrusts outwards gripping- blocks by cam action. For radiographie work. sliding plate-holders, governed by a spring and a catch 143, are used. For fluoroscopic examination. for which the box 25 is mainly used, a screen 70 is employed, which is connected, by cords 73 to the cords 51 so as to remain always opposite the tube box. A standard 104 guided by the rails 10, 102 may serve to support the X-ray tube for radiograph purposes.
