Title: Improvements in or relating to recording and reproducing devices
IPC: G11B17/24
Filed: 1951-10-24
Abstract: 707,922. Digital electric calculating-apparatus. RABINOW, J. Oct. 24, 1951 [March 14, 1951], No. 24891/51. Class 106 (1). [Also in Group XXXVIII] An information storage device, more particularly for use in an electronic computer, comprises rotatably mounted discs, means for recording information thereon and reproducing information therefrom, movable in a plane at right angles to the planes of the discs through cut-away portions of the latter under the control of disc-selecting mechanism, and means to rotate a selected disc. The discs may be reduced to mere sectors. The discs 50 are rotatable on hubs carried by rectangular-section arcuate supports 54 clamped to a base to form a circle. The discs are held by sprung-ball detents in their normal positions in which notches allow rotation of a bracket 20 fast on a shaft 18 and carrying a motor 24 driving rubber feed rollers 72, 78, idler rollers 80, 82 and several recording and reproducing heads 26 associated with a corresponding number of tracks on each disc and selected for operation by switch means. A selected disc is brought into engagement with the feed rollers by momentary energization of an electromagnet mounted in the shaft 18 and rocking a lever 36 carried by an arm 32 fixed to the shaft. A rod 38 is thus pulled upwardly, a spring finger 40 carried thereby engaging a lug 48 on the disc to rotate the latter until it is engaged by the feed rollers. The finger 40 and a stop lever 142, temporarily rocked out of the path of the lug 48 by the rod 38, stop the disc after one revolution. In order to select a disc, a corresponding switch is closed to energize one or other of the windings of a reversible motor 90, the circuit being completed through a wiper contact 110 and a spiral conductor 106 on a drum 100 driven by the motor and carrying the shaft 18. The conductor 106 extends for just over two revolutions and is broken at its centre 107. The motor drives in one direction or the other according to which half of the conductor 106 is engaged by the marked wiper 110. The shaft 18 is rotated until the wiper reaches the gap 107, when the motor circuit is broken. A relay in the motor circuit prevents operation of the electromagnet in the shaft 18 while the latter is being positioned. In a modification, Fig. 10 (not shown), the discs are arranged in a straight line and the support for the bracket 20 is moved linearly by a belt driven with the drum 100. The selecting movement may be controlled by servomechanism or mechanical stops may be used. When the discs are reduced to sectors, the selected disc may be given an oscillatory movement, the driver remaining engaged therewith. Several groups of recording and reproducing heads may be employed to reduce the average access time, and the individual heads may be staggered to permit of more closely spaced tracks. The recording may be carried out magnetically, photo-electrically or by an engraving stylus. Information is normally stored in pulse-coded form but voice sounds may also be recorded on the discs.

Abstract: 476,554. Batteries. MACCALLUM, F., and REDFERN, A. H. March 9, 1936, No. 24996/35. [Class 53] A diaphragm for separating the electrodes in a dry battery consists of a number of paper or other porous sheets some or all of which are coated with electrolyte, the sheets being pressed together to form a laminated diaphragm. Fig. 2 shows a diaphragm 8 formed in this way and Fig. 1 shows a dry battery incorporating such diaphragms between zinc plates 5 and depolarizing tablets 7 which abut against carbon electrodes 6 which may consist of coatings on the zinc plates to form bipolar electrodes. The battery thus comprising a number of cells in series is covered with an elastic laminated skin which may be of the kind described in Specifications 423,165, and 466,597, [Group I]. The diaphragm 8 may be used in cylindrical cells with rod or plate type carbon electrodes surrounded by the usual cylindrical mass of depolarizer. The sheets of the diaphragm are preferably stepped in this case so that when bent into cylindrical form the joins formed by the meeting edges do not coincide. The diaphragm may consist of four to ten sheets of paper, each one thousandth of an inch thick and may be made by first coating a continuous length of paper by unwinding it from a roll and passing it through a bath of electrolyte and then between a pair of squeezing rollers or by applying the electrolyte to the paper by rollers or endless bands dipping in the electrolyte. The coated paper is then cut into sheets of the required size. The various sheets forming the diaphragm may be coated with different electrolytes. The sheet lying next to the zinc electrode may for example be coated with mercury chloride, zinc and ammonium chlorides being applied to the remaining sheets the amount of zinc chloride decreasing towards the sheet adjacent the carbon electrode.
