IPC: G01R11/60
Abstract: 541,150. Supply meters. RICHARDSON, T. C. May 13, 1940, No. 8594. [Class 37] In a maximum demand indicator means under the control of a timing motor are provided for temporarily coupling this motor with the demand element at the end of each time period so that the motor moves the demand element to its zero position. The meter disc 1 drives, through worm gear 3, 4 and change gears 6, a shaft 7 carrying a pinion 8 which meshes with a gear-wheel 9. This is loosely mounted on the demand shaft 10, with which it has driving engagement through a slipping clutch 11 held in engagement by a spring 11a. The demand shaft 10 carries a demand position 12, and the change gears 6 are so chosen that this pointer rotates through fivesixths of a revolution when the meter is operated at rated full load continuously for the duration of the predetermined time periods. The maximum demand pointer 13 is pushed forwards by an abutment 14 on the demand pointer 12. The timing motor 15 is a slow speed synchronous motor and drives a resetting shaft 16 through gearing 17, 18. At its right-hand end the resetting shaft 16 is journalled for universal movement, and at its left-hand end is journalled in a lever 19 which is pivoted on a pin 20 and engaged by a spring 21. The resetting shaft 16 carries a pinion 22 which is loosely mounted on the shaft but coupled with it through a slipping clutch 23 held in engagement by a spring 24. During resetting the pinion 22 engages a gearwheel fixed to the demand shaft 10. A control shaft 26 is driven from the re-setting shaft 16 through gearing 28, 29, 30, 31 and has fixed to it a cam disc 32 having a notch 33. A second cam disc 34 having a notch 35 is mounted on a sleeve 36 loosely mounted on the shaft 26 and is driven through a reduction gear train 40, 41, 38, 37 at one-twentieth the speed of the fast cam 32. The lever 19 carries a pin 42 which is pressed against the peripheries of the cams 32, 34 by the spring 21. When the notches of both cams are brought opposite the pin 42 the lever 19 is rotated by the spring 21 so that the pin 42 enters the notches 33, 35 and the pinion 22 engages the gearwheel 25. The demand shaft 10 is then moved by the resetting shaft 16 to zeroize the pointer 12, the clutch 11 slipping to permit this. The trailing edges of the notch 33 is inclined so that continued rotation of the cams moves the pin 42 back on to their peripheries and disengages the shafts 16, 10. The wheel 31 is coupled to the shaft 26 through a three-armed spring plate 43 which does not slip in normal operation but allows the position of the shaft with respect to the gear-wheel to be adjusted for setting the timing of the cams. The resetting arrangement may be constructed as a unitary device comprising the resetting shaft 16, control shaft 26, cams 32, 34, and lever 19 together with the gear trains coupling the shafts, the pinion 22 being positioned for engagement with a gear-wheel on the demand shaft 10 of the meter with which the unitary device is combined. The unit may or may not include the synchronizing motor 15.

Abstract: 1,163,250. Stranding apparatus. FRISCH KABEL-UND VERSEILMASCHINENBAU G.m.b.H. 8 Sept., 1966 [8 Oct., 1965], No. 54122/68. Divided out of 1159042. Heading D1T. A stranding apparatus of the kind in which the elements to be stranded are passed into an elongated box or frame 2 rotating about an axis parallel with its longest edge and which has, at its two ends, sets of wheels over which the stranded cable or rope is passed in a to- and-fro manner from one set of wheels to the other and in which when the box or frame is filled the rope or cable is run out and fresh elements to be stranded are run in, the direction of rotation of the box or frame being reversed during- this next stage, is characterized in that for each direction of rotation a counting mechanism is provided which after an adjustable number of revolutions effects reversal of the drive to the apparatus and brings into operation the counting mechanism appertaining to the new direction of rotation. In Fig. 1 the box or frame 2 is driven by a motor 1 through a transmission 3 and two couplings 4, one coupling when active causing right-hand running of the box or frame and the other coupling, when active, causing lefthand running of the box or frame. Each coupling 4 is associated with a counter 5, which counters are operated by the appertaining coupling and after a predetermined number of revolutions releases its coupling and engages the other coupling. In an alternative arrangement Fig. 2 (not shown) the output of the couplings drives an impulse transmitter. The frequency of the pulses correspond to the speed of rotation and the polarity of the pulses correspond to the direction of rotation. These impulses are transmitted by way of one or the other of two rectifiers (9) in anti-parallel connection to one or the other of two counting mechanisms which after a predetermined number of ,counts releases the operative coupling and brings into operation the other coupling. In Fig. 3 (not shown) a reversible motor (11) drives the frame and an impulse transmitter (13). The transmitter (13) operates counters (14) that take it in turn to reverse the polarity of the motor (11).

Abstract: 1451917 Electrical encoder INTERNATIONAL BUSINESS MACHINES CORP 5 Dec 1973 [26 Dec 1972] 56409/73 Heading G4R A circuit for providing a digital signal 18 when an analog input 14 exceeds a threshold comprises means 21-28 for comparing the input with fixed threshold levels and means 40, 50, 60, 70, 80 for selecting one of these levels to be the threshold in dependence on the results of previous comparisons. Input 14 is derived from the scanning 11, 13 of a document 12, and the output 18 indicates the presence of a "black" or a "white" bit on the scanned document. Signal 14 is compared at 21- 27 with (increasing) voltages V1-V7 from a resistor chain 28 which provide levels 1-7 expressed as percentages of absolute black, levels 1 and 4 (10%, 24.3%) corresponding to light and dark (highcontrast) printing. The outputs from 21-27 are stored (under the control of clockpulses 17') in latches 30 from which the signals corresponding to levels 1-4 are fed to gates 41-44). The outputs from 30 also pass to circuits 70, 80 which cause counters 52, 62 to be in- or decremented by clockpulses 17". The outputs from 52, 62 are decoded and fed back to 70, 80. The most significant output bits 51, 61 of each counter are fed back to control gates 41-44: they form a Gray code sequence 00-10-11-01 which effectively identifies the output threshold with levels 1 to 4 in turn. In effect, counters 52, 62 record the numbers of certain sets of the levels which have already occurred and adjust the threshold accordingly. The decoder outputs co-operate with 70 and 80 to ensure that 52, 62 do not exceed their pre-set minimum and maximum counts, and that the level transitions occur only in the order 1-2-3-4-3-2-1.
