Title: Tape magazines for magnetic sound recording and/or reproducing mechanisms
IPC: G11B23/04
Filed: 1955-09-29
Abstract: 793,519. Magnetic recording and reproducing apparatus. COUSINO, B. A. Sept. 29, 1955 [Sept. 30, 1954; Oct. 12, 1954; April 11, 1955], No. 27799/55. Class 40 (2). In a magnetic record apparatus, a detachable magazine A contains a spool 20 carrying an endless coil of magnetic tape 17 and is provided with a pair of tape guides 41 which are movable between an upper position, Fig. 3, in which the tape 17 can pass over a magnetic head 7 mounted in the main part of the apparatus, and a lower position, Fig. 5, in which the tape can engage the magnetic head. The guides are held in the upper position by springs until after the magazine has been inserted into an appropriate cavity 10 in the apparatus, where it is retained by catches 55, Figs. 7 and 10. Following the counterclockwise rotation of a control column 14 the guides may then be pressed downwardly by the ends 77 of a U-shaped member 44 mounted on pivots 75 and rocked by a cam-follower 79 on an arm 78 mounted on the control column 14. The same rotation of the column 14 causes a follower 93 to engage the end of a spring-loaded plate 88 and move it so that guide-pins 83 thereon hold the tape 17 in contact with the transducer 7, Fig. 4. At the same time, a roller 87 mounted on a spring- loaded plate 97, pivoted on a point 98 on the plate 88, presses the tape against a capstan shaft 86. The opposite end of plate 97 has a turned-down ear 117 which longitudinally moves a rod 113 coupled through a compression spring 116 to the end of a plate 110 pivoted at 111 and carrying a friction drive-wheel 105 which is coupled to the capstan shaft 86 by a belt 109 and drivingly engages the edge of the bottom plate 21 of the spool 20 carrying the coil of tape 17. When the control column 14 is returned clockwise past its neutral position, a roller 160, Fig. 7, on an arm 60 mounted on the control column, causes the latches 55 to be withdrawn, whereby the magazine A is ejected by members 63 under the influence of coilsprings 65. A spring-loaded bell-crank 69 engaging one of the ejector members 63 and intercepting a projection 68 on the control column 14 prevents rotation of the latter to the operative position until a new magazine has been inserted. Two other embodiments are described with reference to Figs. 15 to 27 (not shown) in which retractable members are provided to press the tape guides downwardly, while in a further embodiment the tape 52b, Fig. 29, is moved from the inoperative position shown therein to an operative position, Fig. 31, by means of pivoted guide members 41b acting under the influence of pins 203a serving to locate the magazine in the apparatus. Specifications 793,520, [Group XXXV], and 793,521 are referred to.

Abstract: 735,562. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 3, 1951 [Nov. 24, 1950], No. 28850/50. Drawings to Specification. Class 40 (3). In a camera pick-up tube having a photocathode on which the pictures to be transmitted are projected and a target electrode which receives photo-emission from the cathode to produce a corresponding electrical image, the photo-emission is controlled by a pulse potential wave applied to the photo-cathode of the tube. The wave pulses between an active level at which the photo-emission is correctly focused upon the target and a level at which the photo. emission is suppressed or greatly reduced, and the active period is controlled either manually or automatically to be approximately equal to the time required for the target elements to reach optimum potential. Generally the active period is made inversely proportional to the average light level incident on the photocathode. In tele-kinematograph transmission the non-active period is made to cover the period of film advance and the active period is controlled in accordance with the film density either by a photo-electric cell responding to light passed through the film, or by control elements constituted by opaque or metallic spots located at the edge of the film at points where the density changes. The active periods are normally arranged to commence with beginning of the normal field blanking and the Specification discloses a circuit employing conventional techniques to generate pulses of adjustable width and amplitude from the normal blanking pulses. The pulse width adjustment element, a resistor in a resistance-capacity coupling network in a pulse amplifier, is arranged for remote control by a motor.

Vacuum apparatus for raising fuel from a tank to an intermediate vessel supplying the carburettor by gravity in which the usual float is dispensed with and the suction and atmospheric valves are operated by an inner vessel which is suspended in the intermediate vessel and is depressed against a spring when it contains a predetermined quantity of fuel. The vessel a supplies the carburettor by a pipe y and is open to the atmosphere. It contains an inner vessel c suspended by a spring r. The fuel from the tank is supplied by a branch m and a tube o to the inner vessel which is in communication with the source of suction through a branch p, passages p<1>, q, and the annular space round the tube o, when the valve f is raised. The vessel c is in communication with the atmosphere through the outer vessel, a pipe u, passages u<1>, u<2>, and the annular space, round the tube o, when the lower valve e is in the position shown. The hollow stem of the valve e is screwed to the inner vessel so that the valve and vessel move together, and the hollow stem of the valve f rests on the valve e, its lower end being serrated to afford communication between the passage u<2> and the annular space round the tube o. In the position of the parts shown, the vessel c, containing the predetermined quantity of fuel, has dropped against the action of the spring, closing the suction valve f and opening the air valve e. The discharge valve w now opens, allowing the fuel to fall into the outer vessel, whereupon the inner vessel is raised by the spring, the air valve e is raised to close the air passage u<2> and the valve f raised to open the suction passage q and allow the vessel c to fill again. When the end of the pipe u is closed by the fuel in the vessel a, communication between the inner vessel and the atmosphere is cut off and flooding prevented. The lower end of the pipe u contains a wick to draw off fluid from the pipe by capillary action and prevent the formation of air locks.
