Title: Improvements in or relating to counting circuits
Inventor: DENBY JAMES FREDERICK
IPC: H04M1/272
Filed: 1954-09-25
Abstract: 766,843. Electronic counting apparatus. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Sept. 25, 1954, No. 27742/54. Class 106 (1). ). A counting circuit comprises cascaded stages each having a pair of gas discharge tubes rendered conducting alternately in response to successive pulses and the last stage has an output lead connected to each of the two tubes whereas each of the other stages has a single output lead connected to one of its tubes. For counting telephone dialling pulses occurring in trains of not more than ten pulses each, three stages are provided. On receipt of the first pulse of a train, a constantly primed tube BD in the first stage is fired and primes an auxiliary tube PRD. The second pulse fires the tube PRD which at once fires the second registering tube BCA of the first stage and the first tube BF of the second stage, both of which are constantly primed. When the tube BCA fires, the tube BD is extinguished. The fourth pulse, through the tube PRD fires the auxiliary tube PRF of the second stage which in turn fires the second registering tube BEA of that stage and the first tube BH of the third stage, which remains conducting until the eighth pulse which, through the auxiliary tube PRH of the third stage, fires the second tube BJ. The first tube of each stage is arranged, when conducting, to prime a corresponding output tube PRW, PRX, or PRY, and the second registering tube BJ of the third stage, which only conducts after eight pulses have been registered, then primes an output tube PRZ. The four output tubes are fired, in a combination to represent in binary form the digit registered at the end of a pulse train by the firing of either of two further tubes BA, BB controlled by relays energized respectively by the first stage tubes BD and BCA, delay circuits ensuring that the tube BA or BB fires only at the end of a pulse train. At this time, a tube D is also fired, through a further delay circuit, to actuate a sequence switch to select the appropriate decimal order of a multi-denominational storage device, also comprising gas discharge tubes, to which the setting of the output tubes is transferred. Firing of the tube D in turn fires further tubes BCB, BEB and BG in the three stages which extinguish the registering tubes. The. relay BD also serves, when energized, to supply H.T. to the auxiliary tubes PRD, PRF, PRH so that these tubes are extinguished as the registration of each even-numbered pulse is completed.

Title: Photoelectric Microscopes.
IPC: G02B21/00
Filed: 1967-06-16
Abstract: 1,161,917. Photo-electric microscopes. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. June 16, 1967 [Oct.18, 1966], No.27936/67. Heading G1A. [Also in Divisions G3 and H3] A photo-electric microscope of the type comprising a vibrating member for scanning the field of view is provided with means for deriving a first error signal dependent upon amplitude errors in the vibration and a second error signal dependent upon asymmetry of the vibration about a datum position and means utilizing these signals to correct any amplitude or symmetry errors in the vibration. Rigidly attached to the vibrating member (which may be a shutter, mirror or parallel sided glass block) is an auxiliary mirror 19. Two beams of light produced by a collimating lens 12 and diaphragm 14 are reflected on to a further diaphragm 20 having a slot 21 through which the beams may pass to a photo-cell 22. The separation of the beams is #2/2 times the amplitude of their oscillation across the slot 21 so that when the vibration of the mirror is symmetrical and of the right amplitude, the photo-cell 22 produces equally spaced pulses. The photo-cell pulses are fed to a differentiator and shaper 24 to produce short pulses which repeatedly set and reset a bi-stable circuit 26. Any amplitude error causes a variation from unity in the mark/space ratio of the bi-stable output and this is detected by a low pass filter 27 to give a D.C. amplitude error signal Va. The error signal controls the gain of a circuit 29 supplying current to the vibrating member to keep the vibrational amplitude constant. The pulses from one side only of bi-stable 26 repeatedly set and reset a further bi-stable 31. Any asymmetry in the vibration causes the mark/space ratio of the output of bi-stable 31 to vary from unity and this variation is detected by a low pass filter 32 which produces a D. C. symmetry error signal Vs which is added to the vibration current from circuit 29 to reduce any symmetry error. In modifications, the signal Vs may be combined with the output of circuit 29 before passing through a common power amplifier, Fig. 10 (not shown) and the source of light 11 may be eliminated by taking light from the light source of the photo-electric microscope itself, Fig. 2 (not shown).

Abstract: 994,785. Electric correspondence control systems. BELL & HOWELL CO. Aug. 4, 1961 [Aug. 8, 1960], No. 28372/61. Heading G1N. A servo system for precisely positioning a tool, for example in an aspheric lens grinding machine, includes a screw and a nut forming a capacitor which is connected in a bridge circuit, the phase difference between an A.C. applied to the bridge and the output from the bridge being used to control the position of the tool relative to means for moving the tool. An electric motor 12 drives a feed screw 11 to advance a drive carriage 14, and with it a tool carriage 18 carrying a tool 19. Carriage 14 is connected to carriage 18 by a magnetostrictive transducer, and carriage 18 also carries nut 20 for movement relative to screw 15 which is coupled to feed screw 11. Screw 15 and nut 20 have co-operating thread face portions 15a, 20a and 20b which are connected in a bridge circuit 31 supplied with A.C. from a ten kilocycle oscillator 37. The bridge output is fed through amplifier 42 to a phase discriminator 40, where its phase is compared with a reference phase from oscillator 37. The D.C. output from the discriminator is fed through filter 44 to an emitter-follower 51, amplifier 52, and trigger stage 53, whose output is fed through resistancecapacitance network 55 to winding 56 on transducer 17. If tool carriage 18 lags behind its correct position by more than half a micro-inch the output from the phase discriminator is sufficient to trigger unit 53 and energize the transducer, whereupon magnetostrictive core 57 lengthens and corrects the tool position. As the position error falls below half a micro-inch the trigger unit output decays slowly through the RC-network 55, whereupon core 57 contracts, and the error is again detected and corrected. In a second embodiment the bridge output is fed through three emitter followers and three amplifiers, arranged alternately. In a third embodiment the output of the phase discriminator is fed through amplifying and trigger stages, as before, and is then applied to a transistor valving circuit. Specification 994,786 is referred to.
