Patent GB-1134920-A (GB)
Title: Tape winding device
IPC: G06K13/26
Filed: 1967-05-22
Abstract: 1,134,920. Feeding webs. NATIONAL CASH REGISTER CO. 22 May, 1967 [16 June, 1966], No. 23568/67. Heading B8R. [Also in Divisions F2 and G5] A tape-winding device, particularly for moving a tape through character-reading equipment for data processing, has means for starting the winding of the tape on to a driven winding-spool comprising a number of flexible curved tape guide members angularly-spaced around the spool, pressure means urging the guide members towards the spool to cause the tape to be brought into frictional engagement with the spool to bind it thereon during an initial winding operation, and a release device which disables the pressure means after the initial winding to permit winding of the tape to continue freely. Initially, the leading end of the tape 30 is passed through the reading equipment over a continuously-driven roller 12 and a guide ramp 32 to a spool 36, described below, mounted on a shaft 38. A control mechanism causes a solenoid 19 to be energized to move a roller 14 into engagement with the roller 12 for feeding the tape 30. At the same time, another solenoid 54 is energized which causes the winding shaft 38 to be driven through a friction-clutch arrangement at such a speed that the tape is wound under tension. Three flexible guide members 66, 68, 76 pivotally mounted at 67, 69, 77 respectively have rollers 90 at their free ends. When winding begins, a solenoid 84 is energized and through a linkage 70, 71 causes the guides 68, 76 to be pressed towards the spool and the rollers 90 to press the tape against the spool. In this position an extension 88 of the guide 68 engages a pivoted arm 86 so that the latter bears against the guide 66 to hold this guide in spool-engaging position. When a predetermined number of turns have been wound, the outward bending of the guide 66 opens a switch 92 in the circuit of the solenoid 84, whereupon the guides 68, 76 are withdrawn from the spool. Also, the extension 88 of the guide 68 is moved away from the arm 86 so that no pressure is applied to the guide 66 and the tape roll is free to wind without interference from the guide members. When a maximum number of windings have been made on the spool, a switch 96 is engaged by the roll and opened to stop the winding device. The spool 36, Fig. 4, comprises a hub 42 for fitting over the wind-up spindle 38, and a handle 39. Circumferentially-spaced slots 44 are provided in the hub 42. Within the hub are leaf springs 48 carrying rubber pads 46, there being one pad 46 adjacent to each slot 44. When the spool is placed over the shaft 38, the latter engages the springs 48 so as to move the pads 46 outwardly through the slots 44 so that they form friction surfaces upon which the tape is wound. When the spool with a wound roll is removed from the shaft 38, the pads are withdrawn into the hub by the springs 48 so that the roll is easily detached.

The chamber 15 is defined by a conducting tube 16, an insulating tube 17 and the plates 5, 8 with the sleeve 18 extending through the annular space between the plates into liquid helium B. The chamber is surrounded by an outer vessel 10 defined by a conducting shell 11 and an insulating member 13 and is filled with helium vapour A. A nitrogen shield 28 surrounds the shell 11. A high-voltage winding 14 with capacitance layers for controlling the potential of the helium in the vessel 10; likewise the increasing diameter of sleeve 18 controls the potential of the helium within the chamber 15. The sleeve 18 rests on a filter 23 which reduces oscillations of the helium B which on vaporizing passes through the space between plates 5, 8 to cool conductors 6, 7 and exit at outlets 25, 26; it is replenished by helium C via a valve 27 which also supplies helium A. In another embodiment (Fig. 2), there is no outer vessel 10 and the conducting tube (16) connects the outer conductors (4, 7). Fig. 3 (not shown) depicts an arrangement in which both cables are superconductors, each inner conductor is surrounded by a respective winding (14) and the opposite ends (19) of a single sleeve (18) extend between the inner and outer conductors at the ends of the cables.

Abstract: 784,729. Electric measuring systems. ARO EQUIPMENT CORPORATION. Aug. 18, 1955, No. 23814/55. Class 40 (1). Apparatus for determining the level of a volatile liquid inside a container by comparing the liquid and gaseous pressures inside the container comprises a moving diaphragm, pressure transducer controlling the slider of a potentiometer whose position is indicated electrically. The transducer comprises a two-part cylindrical chamber 20 (Fig. 2) with a diaphragm 36 clamped between the two parts. The upper part 30 of the chambercommunicates with the gaseous upper space in the main container, and the lower part 32 with the liquid, so that the diaphragm 36 moves in accordance with the difference in pressure on its face against a spring 74 mounted on a slidable rod 54 attached to the centre of the diaphragm. An earthed arm 112 is fixed to the inside of the lower part 32 of the chamber by a leaf spring 114 which presses the arm against a shoulder on an extension of the rod 54, so that as the diaphragm moves with a change in the differential pressure the arm 112 follows, and moves the slider of a potentiometer winding 80, the position of the earthed arm being indicated by a ratiometer instrument 3 (Fig. 4). The shape of the potentiometer 80 is made to correct for the non-linearities of the system, and the ratiometer then indicates the level of liquid in the main container. The shape of the upper part 30 of the transducer chamber 20 conforms with that of the extended diaphragm so that excessive liquid pressure does not distort the diaphragm.
