Title: Improvements relating to preparation of printed circuits
Inventor: OLIVER CYRIL VICTOR
IPC: H05K3/00
Filed: 1965-09-13
Abstract: 1,145,242. Programmed control. BRITISH AIRCRAFT CORP. Ltd. Sept. 2, 1966 [Sept. 13, 1965], No.38950/65. Heading G3N. A master print is prepared from an original circuit diagram, by recording data corresponding to the position and character of each element of a track in the original circuit diagram on a record strip, sensing the data to derive signals for selecting a silhouette to be optically exposed on to a film or plate and between exposures relatively moving the film or plate for the next exposure, so that a reproduction of the original circuit diagram is built up step by step on the film or plate, which is subsequently developed to obtain the required master print. As shown, Fig. 1, a film to be exposed is mounted on a co-ordinate table 2 and illuminated by an optical system comprising a flash-lamp, not shown, mounted in the centre of an annular prism 3 distributing light around the periphery of a plate 4. Light is reflected downwards through circular holes in the plate, each holding a condenser, not shown, on to a carrier plate 5 having holes in which are mounted silhouettes of the track elements. Beneath this plate are tubular masks 7 below which is a plate 6 containing collimating lenses. A prism 9 is rotated about the axis of a lens 10 to project an image of a selected silhouette on the film. The original circuit is converted into data which is recorded on a tape and subsequently reproduced by a tape reader 30, Fig. 4, to derive electrical signals which are fed to a memory 29 which separately stores, X and Y position data, the track element silhouette required and the stepping or repeat command. The silhouette of the track element is initially selected by a control 33 positioning the prism 9, the co-ordinate table 2 is then positioned by Geneva type drives 31 and the control circuit then generates a trigger signal for a flash unit 34. A confirmatory flash monitor signal from the unit 34 indicates that an exposure has been made. A step and repeat facility is provided whereby the table is automatically moved in steps between programmed co-ordinate positions to build up a continuous track on the film.

Title: Improvements in or relating to chucks
IPC: B23Q3/06
Filed: 1964-09-28
Abstract: 1,075,480. Chucks. N. C. NIKITAS. Sept. 28, 1964 [Oct. 2, 1963], No. 39457/64. Heading B3B. A chuck comprises a hollow body portion 10 which houses a collet 22, the collet gripping action being effected by a tapered sleeve 20 which is actuated by fluid pressure via plungers 40 of pistons 38. The fluid pressure is admitted through a connector 58 to ports 52 and annular groove 54. The collet jaws are resiliently mounted in rubber which permits a wider range of workpiece diameters to be accommodated. Initial setting of the collet is effected by screw means 72 which acts on the tapered sleeve 20. Radial ports 76 in the body portion 10 permit the removal, by air blast, of waste material which accumulates in the chuck body during operation. An adjustable rest or stop member 36 is situated at inner end of the chuck jaws which provides means for locating similar workpieces in the same position in the chuck.

Abstract: 1,087,365. Determining number of vehicles in and completeness of trains. SIEMENS A.G. Sept. 16, 1965 [Sept. 16, 1964], No. 39645/65. Heading B7N. [Also in Division G4] Apparatus for determining the length of a train comprises an interrogating pulse generator JG on an end vehicle T of the train, an interrogating signal channel LA connecting the end vehicle to each other vehicle W 1 -W 3  of the train, an answering signal channel LB connecting each other vehicle to an evaluating device Z on the end vehicle and delay elements U, V and cross connecting elements E on each other vehicle whereby in response to a single interrogating pulse the evaluating device receives a series of pulses equal to the number of vehicles in the train. This information indicative of the train length is then transmitted to a central station automatically controlling the progress of the train. The delay elements may be in either channel or both and means may be provided on extra long vehicles to return two pulses from the vehicle to the evaluating device. Similar apparatus may be provided on each vehicle including the end vehicle, Figs. 3, 5 and 7 (not shown), the pulse generators of the other vehicles being gated out of operation by the interrogating pulse from the first vehicle and each evaluating device counting the number of succeeding vehicles in the train in the direction of interrogating pulse transmission. The evaluating device is a two-cycle arrangement, the count obtained in one cycle being stored and compared with the count obtained in the second cycle. Transmission to the central station only taking place when the counts are equal. The count obtained is also an indication of the completeness of the train.

Abstract: 868,906. Frequency discriminators. WORTHINGTON, J. V. (Byford Labs. Inc.). Nov. 24, 1959, No. 39772/59. Class 40(5). A frequency discriminator for frequency modulated pulses comprises a magnetostinctive delay line 14, a transmitting coil 13 and a twopart receiving coil, 16, 17 surrounding said line, biased by a magnet 18 so that 16, 17 produce sinusoidal pulses of opposite polarity in response to a receiver pulse. Said sinusoidal pulses are supplied to rectifiers 21, 22 which are normally cut off and are rendered conducting by regularly spaced pulses from a pulse generator 25 so that the output to amplifier 20 will consist of a series of amplitude modulated pulses formed by the gating sinusoidal pulses of opposite polarity by pulses from generator 25, the amplitude of these a.m. pulses being proportioned to the recurrence frequency of the frequency modulated pulses. These amplitude modulated pulses are then transformed into a sine wave of a frequency equal to the frequency of the modulation frequency.

Filed: 1971-08-09
Abstract: 1361610 Automatic control of attitude PLESSEY CO Ltd 9 Aug 1970 [24 Aug 1970] 40592/70 Heading G3R [Also in Division G5] In an arrangement for reducing tracking error in a disc record player, a servo controlled system is provided for correcting detected deviations of the longitudinal axis of a pick-up arm from a tangential position with respect to the record groove being scanned as the pick-up stylus moves over a radius of the record. Pick-up arm 1 is horizontally pivoted at 4 and 5 to a bracket 2 which is vertically pivoted 3 on a carriage 11 which is driven by a servo motor along rails 13, 14 extending parallel to a radial path over the record. The bracket is connected by an extension 6 to an iron core 7 extending through coils 8, 9 and 10 mounted on the carriage. The middle coil 9 is connected to an oscillator and the two outer coils to a balance detector. The configuration is such that when the pick-up arm longitudinal axis is tangential to the groove being scanned the arm axis is at right angles to the carriage center line and the core is positioned to provide equal coupling between coils 9 and 8 and coils 9 and 10 so that the inputs to the detector are balanced. Any deviation upsetting the balance is detected and used to vary the speed of the servo motor to correct the error. When the pick-up stylus enters the record run out groove, the large out of balance output from the detector, greater than a predetermined level, is used to operate a trip mechanism which lifts the arm and returns it to its rest position. The inductive coupling shown can be replaced by a capacitive arrangement Fig. 4 (not shown).
