Abstract: 1,202,112. Cutting paper tubes. E. W. RONAI. 6 Aug., 1968 [23 Aug., 1967; 30 Nov., 1967], No. 37515/68. Heading B4B. A method of cutting tubing 22 wound from a strip or strips 21, 22 of sheet material on a mandrel 10, into predetermined lengths, comprises feeding periodically a rotary helical cutter 42 into contact with the tubing and then withdrawing the cutter from the tubing. The mandrel 11 is clamped at one end to the winding machine base 13 by a support 14 and is provided at its other end with a rotatable portion 25 connected to a shaft 12. The cutter comprises a blade 42 helically mounted on a shell (66, Fig. 3) which is rotatably carried on a core 67 itself rotatably mounted in bearings 44 on a slide 40. The shell is capable of axial movement on the core in order to compensate for variations in the relative speeds of rotation of the tube and cutter, the cutter being returned to its normal position via springs 69 and (70, Fig. 3). The slide 40 is movable in a frame 31 under the action of cams 51, 52 against the return action of springs 59, 60; the cam-shaft 48 is rotated by a drive motor via a coupling 45, 46.

Title: Improvements in or relating to tape controlled mechanisms
Inventor: BALINT ANDREW
IPC: G05B19/14
Filed: 1967-08-16
Abstract: 1,200,613. Controlling mechanisms; programme control. BELL & HOWELL CO. Aug.16, 1967 [Aug.17, 1966], No.37610/67. Headings G2A, G2C and G3N. A mechanism which can operate in any one of a plurality of different ways each under control of indicia on a tape of a distinct type comprises a control for setting one of the ways of operation; a tape reader including a first means sensing indicia on a tape fed therethrough for controlling the operation of the mechansim and second means for sensing further Identifying indicia on the tape, the second means producing a signal identifying the tape as being of a specific one of the types; and a discrimator which inhibits the operation of the mechansim if the tape type signalled is inappropriate to the way of operation set. As described, this mechanism is incorporated in a film-strip printer in which film to be compied is fed in a forward or in a reverse direction. There are two tape types, one for controlling exposures for forward feeding and known as a forward tape, the other known as a reverse tape. The printer is preset for forward or reverse feed, the control mechanism checks the tape type and operation set before the printing action commences but if the wrong tape type has been inserted, nothing happens until the operator has re-set the printer or changed the tape, in which case the control mechanism again checks the tape and operation set. Switches 62A, 62B, 62C are set for forward or reverse position and when a start button is depressed, a clock 40 emits pulses which causes the tape reader to advance the tape one character position. A reverse tape contains a large hole which is detected by a micro-switch which closes contacts 16. If the switches 62A, 62B, 62C are incorrectly set for a reverse tape, relay contacts 70a are broken and the clock 40 stops, so that the taps is no longer advanced. If however, the switches are correctly set for a reverse tape, there is no circuit to relay 70 and the contacts 70a remain closed, so that the clock continues to emit pulses. For a forward tape with switches 62A, B, C incorrectly set, no large hole is detected and contacts 16 remain open, and relay contacts 70a are again broken, stopping the clock. For a forward tape with switches 62A, B, C correctly set, contacts 70a again remain closed and the clock 40 continues to emit pulses.
