Title: Improvements in and relating to prepayment mechanisms
IPC: G07F15/06
Filed: 1936-03-21
Abstract: 472,598. Prepayment mechanism for basic or fixed charges. UNITED GAS INDUSTRIES, Ltd., and ANGOLD, H. E. March 21, 1936, No. 8548. [Class 27] Price-change mechanism.-In a prepayment mechanism for collecting a fixed charge to be used independently or in conjunction with a prepayment mechanism for the commodity supplied, and employing a constant speed driving element, the constant speed motor 1 drives through reduction gearing a transverse shaft 5 to which is fixed the planet wheel carrier 6 of an epicyclic mechanism having sun-wheels 7, 33 loose on the shaft. The sun-wheel 7 is rigid with a pinion 8 from which two worm shafts 9, 10 are driven at different speeds, one or other of these shafts being in driving engagement with a shaft 17 through a worm wheel 44 or 45 according to the axial position of the shaft 17. A drive from the shaft 17 is taken to an epicyclic mechanism for taking account of the fixed charges and charging arrears as described in Specification 472,597. The sun-wheels 7, 33 are rigid with pairs of arms 34, 35 respectively controlled by a rocking plate 36. When the plate 36 is in the position shown, blocking the arms 34, the wheel 7 is held stationary and the drive from the motor 1 rotates the wheel 33 idly or inoperatively. When the plate 36 is rocked to block the arms 35, the wheel 7 is then rotated and the drive from the motor is transmitted to the fixed charge accounting mechanism. The plate 36 is rocked by pins 41, 42 on the lower arms 38, 39 of a pair of spring-pressed bell-crank levers, the pins engaging a plate 43 rigidly connected to the plate 36. The other arms of the bell-crank levers have pins 40 which coact with notched discs 20, 22. When the pin 40 on lever 39 enters the notch 21 in disc 20 the plate 36 is rocked to block the arms 35. The plate 36 remains in this position until the discs 20, 22 are rotated far enough for the pin on the lever 38 to enter the notch 23 on the disc 22, whereupon the plate 36 is rocked in the opposite direction to block the arms 34. The position of the notch 23 relatively to the notch 21 determines the fixed charge in a particular range of charges. The disc 20 is carried by a sleeve 16 loose on the shaft 17 and rotated from the shaft 5 by a worm 14 and worm-wheel 15. It drives the disc 22 by a pawl and ratchet 24, 26, which allows the disc 22 to be rotated relatively to the disc 20 to adjust the charge. This is done by rotating, by means of a knob or a screw-driver, a spindle 31 having a pinion 30 meshing with a toothed dial 28 connected to the disc 22. The charges are marked on the dial 28 and indicated by a pointer 47. The dial 28 is marked with two ranges of charges and the pointer 47 is carried by an eccentric 46. By turning the pointer over to indicate one or other of the ranges of charges, the eccentric moves the shaft 17 axially so that it drives through one or other of the shafts 9, 10.

Title: Apparatus for the automatic adjustment of a yarn cleaner
IPC: B65H63/06
Filed: 1970-02-23
Abstract: 1,270,885. Adjustment of yarn cleaner sensitivity; measuring yarn thickness. SCHWEITER ENG. WORKS Ltd. Feb.23, 1970 [March 5, 1969], No.8664/70. Headings G1A and G1N. The sensitivity of a yarn cleaner device comprising a yarn measuring cell connected to an amplifier and a pulse shaper, is automatically adjusted, to compensate for variations in yarn characteristics other than that measured by the cell and in ambient conditions, by generating an average value signal from a predetermined number of signals from the pulse shaper output and using this to control the amplifier gain. In the case of a photo-electric yarn detector, variations in yarn colour, ambient light fluctuations and detector contamination are compensated; with capacitive cells, humidity and moisture changes. Influences due to the yarn being smooth or rough, twisted, or untwisted may also be dealt with. The apparatus of Fig. 2 may be adapted for actuation by the continuous running of the yarn or may be actuated in response to insertions of yarn into the detection zone, which occur after each yarn cleaning (cutting) operation. With reference to the latter case, on each insertion, switch d in the pulse shaper circuit 4 is closed for a predetermined time, capacitor 14 charging up to the amplitude of the amplifier 3 output. The voltage on capacitor 14, modified by impedance matching circuit 16, is transmitted, on subsequent momentary closure of switch e, as a pulse to threshold evaluation circuit 5 (feeding cleaner 6) and to the pulse evaluation circuitry 10, 11, 12. The above-mentioned predetermined number of signals (pulses) are counted by binary counter 11, which on reaching the predetermined count initiates a timed sequence of pulses on outputs 22, 23, 24. Pulses due to repeated yarn insertions and consequent closures of switch e are cumulatively stored in prestorage capacitor 26 until the predetermined count is attained in counter 11. Then, in accordance with the timed sequence, a pulse on 22 momentarily closes switch a, resulting in clearing of main storage capacitor 28; a pulse on 23 closes switch f, resulting in transfer of the sum voltage in capacitor 26 to main capacitor 28; and a pulse on 24 closes switch b to clear capacitor 26 and prepare for a new averaging cycle. The output from 12 (via impedance matcher 33) is applied to a control device 7 - a bridge network or thermistor - to operate on the amplifier gain. In the case in which a continuous running yarn is utilized to produce the signals for averaging, switches d and e are periodically sequentially closed under the control of a pulse transmitter. Coarse adjustment of amplifier gain in accordance with yarn quality or number is by manual precontrol 34.
