    Abstract: 1,011,373. Random access storage for records; statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 30, 1963 [Aug. 30, 1962], No. 34310/63. Headings G4M and G5R. Information storage apparatus comprises a plurality of storage channels each containing a record member and a pneumatic device adapted to eject a record from a selected storage channel. In Fig. 2 rectangular records 10 are stored in slots 14 formed in a storage member 12. Each slot 14 comprises a shallow rear portion 16 and a deeper forward portion 18 provided with grooves 24 on each side for engaging the edges of the record. If the record is five thousandths of an inch thick the rear portion 16 should have a depth of about six thousandths of an inch, and the spacing between upper and lower walls of forward portion 18 should be at least 0À018 inch, smaller spacing leading to instability when air is blown over the record by the ejector means. The ejector means comprises an air gun 32 adapted to be moved by solenoids (not shown) into a first position, where its nozzle is horizontally displaced from a channel 30 connected to the rear of a slot 14 so that the flow of air across the mouth of the channel 30 causes suction to be applied to the channel, or into a second position adjacent channel 30 so that air pressure is applied to the channel to blast the record 10 out of the storage member. The gun may be movable vertically to select a desired record, but preferably the gun is fixed in the vertical plane and the storage member 12 is movable. The record may be blasted clear of the storage member and after use the leading edge of the record may be fed into the slot 14 by an external feeding mechanism, the suction applied by the gun 32 then drawing the record completely into the storage means. Alternatively, Fig. 6 (not shown), the transducing station may be provided adjacent the storage means and may include a stop so that only part of the record is expelled from a slot 14; no external feeding mechanism is then required. If the record is in the form of a disc, each channel 30 may communicate with its associated rear portion 16 via a plurality of subchannels to apply the air pressure more uniformly along the rear edge of the disc, Fig. 7 (not shown). Another arrangement shown in plan in Fig. 5 allows the height of slots 14 1 to be reduced, and therefore for closer spacing of records in the storage member. The record strip (not shown) has a 45 degrees cut along the rear corner and is fed into the slot by external driving means. The record is driven out of the slot by an air blast applied through channel 30 1 to the cut edge of the strip. The air escapes through a duct 45 to atmosphere so there is little flow over the faces of the strip and consequently little tendency for the strip to vibrate. Specification 1,000,778 is referred to.

    Abstract: 1,000,778. Random access disc-record stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 13, 1963 [Aug. 15, 1962], No. 31882/63. Heading G5R. To transfer a disc record 10 from a groove in a storage bin 12 along a pneumatically-lubricated guide 36 to a transducing station, an ejector 14 imparts sufficient momentum to the record to carry it to rotatory means 82. The storage bin 12 is movable transversely to a precise position by a piston adder 38 to select the desired record and the ejector 14, which usually applies suction to retain the record, applies pressure to blow it out of the bin. The guide bars 50 are each provided with a record-supporting groove and are formed of foraminous material through which air is forced to provide an air-lubricated path. At the transducing station, the record is rotated by rotatory means 82 after location by means 62 supplied with suction by a valve 63. The arrival of the record is sensed by means 74 which then applies air pressure to a clutch 85 to engage the drive means 82 with the record. The engagement of the means 82 changes over contacts 68, 90 and 91 which:- (a) de-energize valve 63 and energize valve 70 causing air pressure to be applied to the sides of the device 62; (b) cause suction to be applied to the face of the rotatory means 82 through tube 94 to grip the record; and (c) cause a motor 84 to start rotating the record relative to a transducer 101. The record is returned to the storage bin either by reversing the above procedure, or by releasing the still-rotating record from the device 82, whereupon it rolls back into the bin under its own momentum. In an alternative embodiment (Fig. 2, not shown) the record is stored, transferred and transduced in a horizontal plane. In this case, additional guides between the guide-bars 50 support the weight of the record.
