Title: Improvements in or relating to electrical counters
IPC: G06F7/52
Filed: 1960-09-29
Abstract: 897,915. Complementing counters. KIENZLE APPARATE G.m.b.H. Sept. 29, 1960 [Oct. 19, 1959], No. 33464/60. Class 106 (1). Complementing on 10 a counter consisting of magnetic core stages is effected by setting the 0 stage to one while retaining the value it is required to complement and stepping the counter until the original value is stepped out. If the complement on 9 is required the counter is stepped once before the 0 stage is set. Thus, in Fig. 1, to complement 3 on 10 switch 8 is closed momentarily and device 2 enters one at stage 0 of the counter. After a delay control 4 operates to start stepping pulse generator 3. The setting of the counter is successively 3-0, 4-1, 5-2, . . . until -7 when the output from stage 9 is passed through gate TJ to stop stepping pulses. To complement on 9, switch 7 is momentarily closed, when the counter is advanced one stage before being complemented on 10.

Title: Improvements in or relating to variable-tariff prepayment meters or the like
IPC: G07F15/08
Filed: 1933-11-30
Abstract: 429,279. Escapements. ARON ELECTRICITY METER, Ltd., and WHITE, A., 80, Salusbury Road, Kilburn, London. Nov. 30, 1933, No. 33614. [Class 80 (iv)] [See also Groups XVIII and XIX] An adjustable escapement between a controlling wheel 33 driven by the counting train 34 of a prepayment electricity meter and a controlled wheel 21 driven by a spring 40 comprises an epicyclic mechanism 25, 26, 27, the planet wheel 27 rotating bodily with a shaft 24 which carries a wheel 23 geared to the wheel 21. The sun wheels 25, 26 are loose on the shaft and are integral with wheels 29, 30 engaging respectively mutilated pinions 35, 36 driven by the wheel 33. The pinions are eight - tooth pinions with alternate teeth removed and are composed of two side discs connected by rods which form the teeth. They are arranged with the spaces on one pinion in line with the teeth on the other. A rod 41 projects from the wheel 29 and co-operates with two stops 42, 43 on the wheel 30, the stop 42 being fixed and the stop 43 adjustable. If the stops are adjusted so that they embrace as closely as possible the rod 41 as shown the wheels 29, 30 are locked together and the device acts as if it were a single wheel geared to a single unmutilated pinion. This represents the lowest tariff, say one farthing per unit, and the wheel 21 rotates the minimum amount for a definite movement of the wheel 33. If the stop 43 be moved from the stop 42 through an angle of 120 degrees, as soon as a tooth on the pinion 35 comes out of mesh with the wheel 29, the wheel 29 will rotate through 120 degrees until the rod 41 comes against the stop 43. On continued rotation of the pinions, the wheel 30 is next released and rotates through 120 degrees until the stop 42 comes against the rod 41. The wheels 29, 30 thus rotate in steps of 120 degrees and the bodily rotation of the planet wheel 27 allows a correspondingly increased rotation of the wheel 23 and the wheel 21.

Abstract: 607,315. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 21, 1945, No. 34781. Convention date, July 6, 1944. [Class 40 (iii)] [Also in Groups XX and XL (a)] In a television transmitter utilizing a tube of the type in which an electrostatic image of a subject for transmission is formed on a target electrode (e.g. Orthicon) from which secondary electrons are released in an amount proportionate to the intensity of the electrostatic image, an electrode is provided for collecting the released electrons to produce across an impedance connected thereto a D.C. potential of intensity determined by the intensity of the electrostatic image, said potential operating means for controlling the transmission of image signals produced in the tube in accordance with the average light intensity of the subject for transmission. Photo-electrons liberated by a light-responsive surface 12, Fig. 1, in accordance with the light intensity of an optical image formed thereon are accelerated by a ring electrode 20 towards a target surface 16 between which and the surface 12 is located a fine wire mesh screen 18. Secondary electrons from target 16 are collected by screen 18 and produce a P.D. across the impedance element 52, which varies in accordance with the average light intensity of the optical image, i.e. the D.C. correction voltage. This correction voltage is fed to valve 84, the cathode resistor 78 of which forms part of the grid circuit of the modulator amplifier 66, 68 which is thus supplied with a bias varying in accordance with the potential across the impedance 52. Instead of employing the latter potential to control the transmission level in the above manner it may be utilized for the electromagnetic operation of an iris diaphragm (see Group XX) to maintain the light intensity of the optical image substantially! uniform regardless of the light intensity of the object, Fig. 2 (not shown). For optimum operation of the pick-up tube, the average potential of the screen 18 should be altered by' a small amount in accordance with the intensity of the optical image focused on screen 12. This may be-effected manually by means of potentiometer 54 or may be made automatic by means of the circuit of Fig. 3 (not shown) in which the potentiometer is replaced by a high resistance connected to a source of biassing potential.
