Abstract: Two cartridges are shown herein which have the capability of storing a folded endless loop of tape. The cartridges are designed so that by pneumatic pressure the loop of tape may be unloaded from the cartridge by a controlled unfolding and reloaded into the cartridge by a controlled folding. Two cartridges are shown, one containing a porous wall to permit the appropriate air flow to control the folding and unfolding, and the other containing air passages in nonporous walls to control the folding and unfolding.

Abstract: 850,510. Sensing records. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 30, 1959 [June 30, 1958], No. 22425/59. Addition to 838,352. Class 106 (1). [Also in Group XXXVI] The parent Specification describes a means for sensing magnetic marks on statistical records or the like using the photo-magneto-electric effect of semi-conductors, a mark being detected by the voltage it produces across a layer of semi-conductor where it is illuminated with a lamp. In this invention the semi-conductor is subjected to irradiation with a stream of electrons instead of with light. A cathode-ray tube is used as shown in Fig. 2, the semi-conductor layer 40 either forming the end wall of the tube or being placed on the inner side of it. Conductors in the form of four arcuate strips 44 are applied to the edges of the layer 40 and opposite pairs are connected to circuits 50, 52. The record card 54 is placed near the layer and the beam 28 is controlled to sweep out successive horizontal lines covering the area of the card. When the beam registers with a magnetic mark on the card voltages appear on one or the other of the pairs of conductors 44. Sensing characters or digital magnetic records.- The apparatus of Fig. 3 is shown sensing characters printed in magnetic ink on a tape 56. The cathode-ray tube has, on the inside of the end wall, four strips of semi-conductor 81, 82, 83, 84 each with a pair of conductors 89. The electron beam 68 is arranged to be continuously fanned out in a horizontal line across the four semi-conductor strips. The beam is moved vertically to scan the whole character, output signals being derived from the four strips in accordance with the area of the character registering with the strip at any particular position. The character sensed may be identified from these signals by circuitry not described. This apparatus can also be used to sense magnetic bits written serially in four tracks.
