Abstract: 1,171,706. Tape reels. INTERNATIONAL BUSINESS MACHINES CORP. 27 July, 1967 [26 Aug., 1966], No. 34494/67. Heading B8M. [Also in Division G5] In a tape recorder incorporating an automatic, pneumatically-operated tape threading arrangement (see Division G5), a take-up reel 6 is provided with its hub 18 and flanges 16 apertured to allow suction to attract and secure the tape end. The hub is formed with small bores 34 extending parallel to the hub axis which, when the hub is mounted on its drive shaft 14 connect, via ports 25 and circular slot 13 in chamber 17, a source of vacuum to the apertures 23 in the hub surface. In addition, similar larger diameter bores 35 connect larger apertures 21, 22 which extend as grooves in the flanges 16, to the common vacuum source when these are in the section N defined by slot 15. The suction produced by the larger apertures attracts a tape in sector N towards the hub and the tape is secured thereto by the suction of the smaller apertures.

Abstract: A punching mechanism (10) includes a permanent magnet (14) and a pole-piece (20) connected to one pole of the permanent magnet and spaced from the other pole by a gap (G). A movable coil (34) is disposed at least partially within the gap. A punch actuator is connected to the movable coil, and conductors are provided for conducting an electrical current to the coil. Current is supplied to the coil to effect a punching action.

Abstract: 1,138,573. Tape reel cover. INTERNATIONAL BUSINESS MACHINES CORP. 8 Aug., 1967 [8 Sept., 1966], No. 36323/67. Heading A4G. A cover for a reel of magnetic tape has side flanges covering the flanges of the reel, and the cover comprises two channel shaped bands 10 and 16 joined along their length leaving a tunnel between them and containing rubber seals 46 to contact the reel flanges. One side wall 14 of the cover may have fingers 15 for holding documents. A toggle latch can be closed to draw the cover tightly round the reel for storage. In use, the reel and cover are held on a machine in restrainers 48 and 50, with key 53 ensuring correct alignment. The latch 22, 24, 28 is opened either by hand or automatically with opening 25, so that the cover expands into grooves 58 in the restrainers, the end B to 20 of the outer band that is not attached to the inner band moving circumferentially apart from the end A to extend the length of the outer band by a length AB. As the toggle opens, the slide block 32 slides from one end of the window 36 in the outer band to the other, carrying with it the door 38 that extends about a quarter of the way round the circumference between the inner and outer bands. The door 38 slides in a clockwise direction, opening gaps 14 and 44 in the inner and outer bands to form an exit through the cover for the tape end, and aligning the gap 56 in the sliding door with the gap 54 in the tape already aligned with air inlet 52 in the restrainer 50, so that compressed air flows along the channel between the inner and outer bands until it reaches tangentially angled air jet holes 55 and 57. The holes 55 are directed in a clockwise direction, so that air flows clockwise round the reel, urging the end of the tape towards exit 14, 44 where the tape meets air from the holes 57 flowing counter-clockwise to peel off the end of the tape and urge it through the exit.
