Filed: 1973-03-21
Abstract: 1424762 Automatic control of electron-optical apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 21 March 1973 [24 March 1972] 13605/73 Heading G3N The lens current of electron optical apparatus is controlled by an adjusting mechanism comprising an externally operable control member for generating digital control pulses and a digital to analogue converter for converting the pulses to a control signal. Adjusting switch 2 generates add or substact step pulses in combination with clock 5 and circuit 6. The magnitude of each step is set up on switch 4 and circuit 7 either distributes the step pulses from 6 to the correct counter 8 according to the setting of switches 4 or acts as a variable multiplier in which case there is only one counter 8. The counter reading is converted to an analogue control signal by D/A converter 9 which may comprise reed relays as switching elements and is also displayed on NIXIE tubes 10. Preset magnifiction may be generated by switch 11 which enters the desired count value into store 12. This value is compared by comparator 13 with this actual count and the actual count is adjusted by pulses from clock 5. The operation may be controlled using predetermined values in a computer programme.

Title: Oscillating device activated by bi-metallic element
IPC: G09F11/23
Filed: 1953-05-19
Abstract: 731,325. Moving signs. DEMANCO PRODUCTS Inc. May 19, 1953 [Nov. 18, 1952], No. 13986/53. Class 3 (1). [Also in Group XXVI] A device used, e.g. for the animation of advertising devices and the like, comprises an activator in the form of a source of heat or cold which effects oscillations of a resilient bi-metallic element. The device shown in Fig. 1 comprises an electric lamp which heats a shaped bi-metallic strip 24 riveted to a bracket 22 and carrying a "load" 27 such that the strip moves away from the lamp and the centre of gravity 28 of the "load" is caused to pass the dead centre axis 29 for the "load" to thereby amplify the swinging movement. The "load" may comprise an advertising device which is required to oscillate. In a modification a spring for assisting the resilience of the strip to return to the lamp is riveted at 23. In a further modification, Fig. 3, the bi-metallic strip 46 is attached, at 45, to a spring 44 riveted to a support 43. A further embodiment shows a rod, arranged for reciprocation, attached to the junction, such as 45 in Fig. 3, thus enabling the device to give rise to either reciprocatory or, by utilizing a crank shaft, rotatory, as well as oscillatory motion. In a device, Fig. 7, the "load" 68 is pivoted to a strip 66 attached to the bi-metallic strip 64. The riveted supports such as 23 in Fig. 1, 43 in Fig. 3 and 65 in Fig. 7, may be replaced by a spindle and bearing to enable true circular movement to be imparted to the "load". In this case a spring member is provided to extend below the point of attachment of the strip to the spindle and two "stop" members, resilient or otherwise, are provided to limit the travel of the spring member and thus the "load".

Title: Apparatus for use in the measuring or return running of travelling strip, tape and like material
IPC: G11B27/36
Filed: 1953-05-19
Abstract: 744,259. Driving sound film or tape. SHORTER, F. W. T. May 19, 1954 [May 19,. 1953], No. 14033/53. Class 40(2) [Also in Group XVI] In an apparatus for measuring and controlling the return running of a tape, as in a tape recorder, a drum, or the like, during forward motion of the tape, drives a primary control member which on return to the initial position operates to stop the tape movement, a secondary control member being also provided which is driven by the primary member during a forward movement but is held stationary during return movement of the primary member, whereby upon a subsequent forward run the movement of the tape is stopped by the co-operation of the primary and secondary members when the primary member reaches the original forward position. During a forward (recording) operation, the tape rotates a drum 13, Fig. 1, and through a train of gears 15, 16, 17, 18, 19, rotates counterclockwise, as viewed in Fig. 4, a threaded sleeve 14, Fig. 1, mounted in a bearing 25 and carrying an arm P on which are mounted switches x, y, Fig. 4. A secondary arm S, mounted on a threaded spindle 26 in the sleeve 14 rotates therewith during the recording operation, but during a rewinding operation the spindle 26 and arm S becomes locked statiorary by a spring-loaded cylinder .27. Fig. 2. which jams between a plate 31 and a drum 30 fixed to the spindle 26. Thus during a forward (recording) operation a spring 35 within the drum 30 becomes tensed and is held tensed all the while the spindle 26 is locked by the cylinder 27. When the primary arm P reaches its initial position again, a rocker member 32 meets a stop member 33 and closes contacts x to operate a relay to stop the tape. When a play back operation is initiated, the primary arm P rotates until it reaches the forward position from which it left the secondary arm S, whereupon the rocker member 32 contacts a -stop 34 on arm S to open contacts y and stop the tape. At any part of the tape between the two positions described, the arms P and S may be reset to their initial positions ready for a further recording by the operation of a relay R which 'rotates a plate 20 about an axis 21 whereby the cylinder 27 is withdrawn from between the drum 30 and plate 31, so that the spring 35 restores the arm S to the initial position and with it arm P.

Abstract: 770,127. Magnetic recording and reproducing apparatus. LEVIN, S. May 16, 1955, No. 14087/55. Class 40 (2). Apparatus for magnetically recording and reproducing signals comprises a recording and pick-up element which is subjected to means for producing variations of its magnetic properties in predetermined regions thereof in accordance with signals to be recorded, and subjecting a magnetic recording medium to said element whereby variations of flux in said element caused by the variation of the magnetic properties induce magnetization accordingly in the record medium. The apparatus is of particular interest for recording a wide band of information and is described with reference to the recording and reproduction of video signals. Figs. 1 and 2 show a magnetic recording element 16 in the shape of a toroid, the portion 18 of which forms the target end of a cathoderay tube. In one mode of operation with the switch 14 in position B, video signals from input stage 29 are fed to the cathode gun 24, 25, 26 and an electron beam focused and subjected to deflection voltages by known means causes local variations in magnetic characteristics of portion 18 of element 16, and causes regional variations of fringing flux produced in a winding 19 by a direct current from a source 31, and thereby induces local magnetic variations in record medium 21. In another mode of operation, with switch 14 in position A, the image signal modulation is applied to winding 19 and a constant high frequency applied to cathode 26. Another embodiment is described with reference to Fig. 7, in which a direct image from a scene or object 45 or a cathoderay tube 46 is thrown upon a cathode 39 from which electrons are focused on to an electrode 38 whereby magnetic changes are produced in element 36 as described in the first embodiment.

In the embodiment described a black- and-white striped filter, the black (opaque) strips corresponding to the red strips of a red, green, blue repeating striped filter, is mounted adjacent the photocathode in place of the input filter and the anode screen imaged on to a black- and-white film. A print of this film is then projected on to a further film which after development is such that it transmits only red light at positions corresponding to the black strips of the black-and-white striped filter and is transparent elsewhere. This operation is then repeated to produce films having green and blue strips and the resulting films combined to form the output filter. The colour coded image on the anode screen of the intensifier may be recorded on a black-and-white film which is subsequently viewed through the output colour striped filter.
