Abstract: 401,563. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Beverage, H. H. ; Riverhead, Long Island, New York, U.S.A.) March 10, 1933, No. 7328. Convention date, March 22, 1932. [Classes 40 (iii) and 40 (v).] In a television transmitter employing carrier currents, variations in the depth of modulation are prevented by the use of a gain-control device operated by the average brightness of the picture. Where a film 11 is to be televised a light-sensitive cell 23 is illuminated, through a ground-glass diffusing-screen 21 if necessary, with an intensity dependent on the average density of the picture at the point 82. The output of this cell is applied, through an amplifier 29, to control the grid potential of an amplifier 51 which deals with the picture current from a cell 47 whereby the picture is scanned at the point 83. The time constant. of the condenser 55 and associated resistances is such as to produce in the gain-control a time lag equal to the time taken by the picture to pass from the point 82 to the point 83. Synchronizing-signals are superimposed from a light-sensitive cell 71 controlled by apertures 69 which send a synchronizing impulse after each line of the picture ; and a different impulse may be sent at the end of each picture frame by a special aperture which may co-operate with a shutter if the disc makes more than one revolution per frame. A reversing-switch 59 enables the system to be applied whether low or high density corresponds to modulation. The film 11 may move intermittently, and in that case a single light-source may be used for both scanning and modulation-control. Sound signals may modulate a sub-carrier which is superposed on the television signals to modulate the main carrier oscillations.

Abstract: 1,201,114. Selective printing. CREED & CO. Ltd. 15 Feb., 1968, No. 7513/68. Heading B6F. A recording tape, Fig. 6, is driven e.g. by a pressure roll and drive wheel 30 or a friction grip (32, Fig. 7) from a drive shaft 17 which is oscillated by an arm 15, Fig. 1, extensibly connected by a slide 14 to a follower arm 5 pivotally connected at 6 to an endless band 4 which when driven by a motor 11 through a clutch 12 gives an accelerating, a constant and a deceleration movement to the drive shaft 17. The tape, Fig. 6, is used to record magnetic images from a mosaic type head, is dusted with ferrographic material and the smooth movements given by the drive prevent the material being thrown off. During recording, the tape is fed from the shaft 17 advanced step-by-step by a magnetic escapement mechanism 20, 21, 22 which rotates a pinion 19 and an arm 2 carrying a guide 1 for the band 4. The slack in the band is taken up during these letter-space movements by the rollers 8, 9. During letter-spacing of the tape the band 4 is fixed on the guide 1, which moves towards guide 3, either by friction or magnetic clutch. When a carriage-return signal is received the motor 11 is clutched at 12 to drive the band 4 clockwise. The connection 6 and arm 5, 15 are rotated by the clockwise drive of the band. During this time the arm 5, 15 first accelerates slowly about pivot 17, then turns at an even speed, and then decelerates as the coupling 6 is moving around guide 3. The motor 11 is reversed to restore arm 2 to starting position but freewheel devices prevent reverse tape feed.
