Title: Improvements in or relating to servo-mechanisms, especially for machine tools
Inventor: PHILLIPS JAMES HUGH
IPC: G05B19/33
Filed: 1955-12-31
Abstract: 852,808. Electric correspondence control systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 31, 1956 [Dec. 31, 1955], No. 37546/55. Class 40 (1). Means for displacing a member 1 in response to input-data by means of a lead-screw 2 driven by a servomotor 3, comprises a differential transformer TR1 for sensing backlash between the member and the leadscrew and inserting a corresponding error signal in the servo-loop associated with the servomotor and the leadscrew. If backlash occurs, an alternating error signal having a phase-sense and amplitude indicative of the direction and amount of the backlash is derived from the transformer and fed to a combining circuit 9, which also has a voltage input representing the angular displacement imparted to the lead-screw by the servomotor 3, derived from an A.C. potentiometer 10. The required position of the slide 1, which carries a workpiece to be milled, is determined by a control-unit 8. The unit 8 sends an amplitude-modulated alternating signal to a differencing circuit 7, which also receives a second signal having a negative polarity compared with the first signal, from the circuit 9. A second differential transformer TR2 detects backlash in the leadscrew mounting, and also sends a signal to the circuit 9. The transformers may have their output windings connected in series with the A.C. potentiometer 10; so that the potentiometer signal is corrected directly. The backlash may be detected by the movement of an iron core within the differential transformers.

Abstract: 1,092,670. Milling. M. VON BUSHE and T. ALTENBRACHT, [trading as TH. KIESERLING & ALBRECHT]. Sept. 3, 1965 [Oct. 24, 1964], No. 37760/65. Headings B3B, B3K and B3N. A tube-end milling machine comprises a plurality of machining positions into which the tubes are transferred by axial and longitudinal movements on a conveyer and roller beds, the tubes being held for machining by means 7a, 7b movable in a vertical plane. A tube is delivered from a shoot to rollers 4 by a conveyer 3 operated by twin eccentrics. The rollers move the tube against a stop 5 before it is carried to the tool 6a and clamped by the jaws 7a, 7b, where it is face-milled and possibly chamfered. It then passes to station 7 where it is chamfered or threaded externally. The tube is next moved laterally by rollers 4a to abut a stop 5a, and then to rollers 4b which move it against a stop 56. Similar machining takes place at stations 8 and 9. Separate motors drive the tools, rollers and conveyer. The clamping jaws such as 10, 10a, Fig. 3, are moved by an hydraulic cylinder (22) carrying the jaw 10 and connected by gearing (22a, 19b), a ring gear (17) and gearing (18a, 18b) to the jaw 10a. In a modification, the tubes are transferred in a horizontal plane and are lifted by the clamps.

Title: Photographic camera
IPC: G03B17/42
Filed: 1973-08-16
Abstract: 1439377 Film transport mechanism EASTMAN KODAK CO 16 Aug 1973 [21 Aug 1972] 38748/73 Heading G2A In a camera which receives roll film having metering perforations, the sensing pawl 74 which detects these perforations is relieved of its spring- loading during an exposure operation so that it does not exert any pressure on the edge of the perforation which may cause unwanted film movement during exposure. As shown, the filmstrip 12 and backing paper 16 is advanced in the direction of arrow 30 by pushing a slide 22 to the left from the Fig. 1 position. A rack 24 on the slide engages a gear sector 26 on which is mounted a ratchet pawl 32, which in turn engages a gear 28. Anti-clockwise rotation of gear 28 winds on the film. As slide 22 returns to the right under the action of a spring 40, gear sector 26 I rotates clockwise, but corresponding rotation of gear 28 is prevented by a ratchet arrangement 46, 44 and a leaf-spring 42. During its film-advancing movement, a projection 60 on slide 22 engages and pivots clockwise a high-energy lever 54 into the Fig. 1 position, against spring 40, in which position it is retained by a tab 52 thereon which latches over the end of a shutter release lever 56. The sensing pawl 74, urged towards the film by a spring 78, and also urged anti-clockwise by a tab 84 on a spring-loaded control member 80, rests on the film, as shown in Fig. 2, until it aligns with a metering perforation 14, when it enters the perforation, and is then drawn by the film in direction 30, so that both pawl 74 and member 80 are pivoted clockwise into the position of Fig. 1. During this movement the metering lever 62 is released, to be pivoted anti-clockwise by spring 68 so that pawl 66 thereon engages with ratchet 44 to prevent any further winding on of the film. After slide 22 has returned to the  "ready for exposure" position of Fig. 1, the clockwise rotation of gear sector 26 has brought its lower end into engagement with one end of a lever 86, and pivoted it anti-clockwise. Its other end is thus brought into engagement with a tab 90 on member 80 and pivots the member clockwise against its loading spring 82. Thus pawl 74 is relieved of the force of spring 82, which would tend to pivot it anti-clockwise, via tab 84, during the exposure period, so that it has no tendency to move the film during this period. In the modifications of Figs. (not shown) 3-6 other methods of relieving the spring tension on pawl 74 during the exposure period are disclosed.

Abstract: 1,071,960. Gating circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Sept. 23, 1964 [Oct. 9, 1963], No. 38762/64. Headings H3P and H3T. In a system where pulses are fed into and out of a two-wire transmission line by means of transformers, diode gating circuits are arranged in the secondary circuits of the output transformers to switch pulses to the appropriate loads. In the Figure the pulses enter at one or more points 9 along the line, which may be connected also to remote input and output points by matching resistors 18, 19. Each output transformer 3, 4, 20, 21 feeds a load 10, 11 (e.g. pulse amplifier, shift register) via a diode 12, 13 which can be switched between high and low conductivity states by voltage from a transistor 16, 17. Any effect of the switching voltage on the load is reduced by oppositely connected diodes 23, 24; these are unnecessary if the load has a threshold input. If the load integrates the received pulses, the effect of interference is reduced. For use in a computer, a plurality of such circuits are used with common input. The switch 16 may be common to all the loads to be switched simultaneously.

As described (Fig. 3) video signals are converted to eight bit binary form and parity bits P1-P4 are derived in exclusive OR gates from bits 2, 3; 3,4; 1,4; 1,2 (where bit 1 is the most significant bit). The output 12 from a voltage controlled oscillator maintained at three times the frequency of the incoming subcarrier is used as the reference for a phase comparator controlling a further voltage controlled oscillator pulsing a divide-by-12 counter, the outputs 14, 15, 16 of which, after inversion, control exclusive OR gates receiving the data and parity signals to control AND gates, the outputs 27, 37, 47, 57, from which are fed to four latches connected selectively and sequentially to five heads spaced at 72 degree intervals around a drum which the video tape contacts. To reproduce the recorded data (Fig. 4) the output from each head is fed directly and via a delay to an exclusive OR gate controlling via a phase comparator a voltage controlled oscillator pulsing a divide-by-12 counter. The counter outputs 13-17 are fed to latches and stored at each output from the exclusive OR gate, the outputs 64, 65, 66 from three of the latches being transferred at the end of the cycle to further latches to give a parity bit, e.g. P1 and two data bits, e.g. 1, 5. These bits are fed to buffer storage and from the data bits, parity bits are generated and compared with the recorded parity bits. A read only memory may be programmed to identify minor errors. A D-to-A converter is used to derive a video output signal
