Title: A tube or tubular package formed from a packing laminate
IPC: B32B15/08
Filed: 1964-05-19
Abstract: 1,013,656. Laminates. TETRA A.B. May 19, 1964 [May 21, 1963], No. 20632/64. Heading B5N. [Also in Division F2] A tubular package is made from a laminate comprising a backing layer 1, preferably of kraft paper having a synthetic resin film 2, preferably of polythene, bonded to one face thereof and forming an overlapping strip 4, by folding the laminate into a tube and securing the inner surface of the overlapping portion 4 to the adjacent portion of the plastics 2 along the opposite longitudinal edge of the laminate. The joint may be a lap joint, a thin layer 3 of a material to which the thermoplastic layer may be heat sealed being provided on the outer surface of the tube. Alternatively (Fig. 2, not shown) the tube joint may be a butt-joint, the layer 3 in this case being replaced by a heat sealing film which projects along the longitudinal edge opposite the overlapping strip 4 to form another strip portion. The folding may be made either as a helical winding, or as a simple curvature of the laminate about the tube axis. The laminate may be produced by extrusion coating a plastics film to a layer 1 of smaller width. Alternatively a plastics film and layer 1 of the same width may be laminated while ensuring the plastics film does not adhere to one edge of the base layer, which edge zone is then removed.

Filed: 1924-09-08
Abstract: 234,338. Western Electric Co., Ltd., (Western Electric Co., Inc.). Sept. 8, 1924. Inductances.-In a four-line telephone or like transmission system comprising two side circuits and a phantom circuit provided with loading coils for each circuit, a separate inductance of a magnitude calculated to reduce side-current to phantom-circuit cross-talk is connected in each of the line windings. In the loading unit shown in Fig. 2 the loading coils 10 for several quads are mounted on hard wood spindles 11 supported in bosses 12 in the bottom of a cast-iron casing 7 having a flange 8 to receive a cover. The spindles 11 are clamped at the top in a spider 13 fastened to the casing. A terminal board 14 of hard wood mounted above the coils is provided with sockets to receive the correcting inductances 16. These are chosen after measurement of the cross-talk between each phantom-circuit and its side-circuits. They are wound on straight cores of silicon steel or iron dust material and are arranged on the board 14 so that there is substantially no magnetic linkage between them. Small non-inductive resistances may also be mounted on the board 14 and connected in the opposite line to that in which the inductances 16 are connected to balance the resistance thereof. Fig. 3 shows the connections for a single quad 24 to side circuit loading coils 21, 22, phantom circuit loading coil 23, balancing inductances 16, 16<a> and balancing resistances 17, 17<a>. The connections to the loading coils from the cable are taken through a central opening in the board 14 and those from the coils to the balancing devices between the board and the casing. Specifications 103,188 and 235,053 are referred to.

Title: Stepping motor systems
IPC: G05B19/40
Filed: 1966-05-13
Abstract: 1,105,598. Electric motors. INTERNATIONAL BUSINESS MACHINES CORPORATION. 13 May, 1966 [10 June, 1965], No. 21261/66. Heading H2A. A stepping motor has a rotor 23 and a plurality of stator windings A1, A2, B1 B2 which are energized in sequence from an external D.C. supply through solid state switch - ing devices which are triggered by a first signal representative of the position of the rotor and a second signal which modifies the energization pattern produced by the first signal. The first signal is obtained by mounting disc 21 having a ring of fifty equally spaced apertures 24 on the rotor shaft. The apertures are spaced so that a different one of the photo-transistors 25-28 is illuminated for each 1À8 degrees step of the rotor. This signal is passed into translator 41 to set each bi-stable circuit (FF1-4), Fig. 7 (not shown), into a state representing the position of the rotor. Second signals are also fed into the translator on lines 46-49, and are used to set gating circuits so that the correct motor windings are energized. The second signal inputs provide (a) a stop command, where the stator windings corresponding to the indicated rotor position are energized to magnetically hold the rotor in that position; (b) a clockwise command, where the stator windings corresponding to a step of 1À8 degrees clockwise are energized; (c) a counter-clockwise command where the stator windings corresponding to a step of 1À8 degrees anticlockwise are energized; and (d) high speed command, which is used after the direction of rotation has been set, where windings corresponding to a double step, i.e. 3À6 degrees, are energized. Since the rotation of the motor rotates position indicating disc 21, different photo-transistors will be illuminated at each step and the bi-stable circuits reset, so that once a command input has been selected the motor will continue to run in the required manner. In a modification a circuit is provided, Fig. 8 (not shown), which automatically changes the input command to high speed when none of the photo-transistors is illuminated, i.e. between steps. A variable delay is included in this circuit so that the motor speed can be raised.

In an accounting machine in which entries are effected simultaneously on an account card, placed in the machine via a front guide 48, and on an advice sheet 103, automatic advice sheet ejection and feeding of a further sheet into printing position is effected. The sheets 103 are supported on a convex plate shelf 51 and are advanced by a one-way friction roller 69 to a first pair of conveying rollers 35-38, a second pair of rollers 34, 37 then move the advice sheet into printing position and are subsequently driven in a reverse direction when the platen pressure feed rollers are released to eject the sheet with the aid of further rollers 36, 39 into a depositing plate 47. A cycle of operations is initiated upon the occurence of a carriage-return movement, whereupon a bar 4, Fig. 2, is raised to trip a catch 3 which, by a driver 7, swings levers 15, 27, the latter closing contacts a to cause the feed rollers 34, 36 to eject a completed form while the former releases a square pin 19 to allow a spring 14 to rotate a starting lever 10 counter-clockwise to cause a member 25 to close the contacts s to start a main drive shaft 62. Rotation of a disc 104 on the shaft 62 first allows contacts h of the driving motor to close, and later restores the member 25, thus opening contacts g and restoring the lever 10 and the associated ports which become locked in the original position. The shaft 12 has discs 64, 73 to control sheet separating, the former reciprocating a rubber roller 69, which free-wheels in the return direction, over the top of the sheet pile 55 while the latter reciprocates holding members 101, 102 through linkage 74-79 in such a way that, while held by the member 101 and released by 102, the rollers 69 bows the top sheet upwards until subsequent re-holding of the pile by the member 102 and release of the top sheet by member 101 allows it to spring forward between guides 40, 41, Fig. 1, to be aligned by temporarily stopped rollers 35, 38. When the sheet has been aligned the disc 64 closes contacts e long enough to cause the rollers 35, 34 to feed the sheet to the correct position relative to the platen 11. Levers are provided to lock the parts to allow introduction of an account sheet or stack of forms and to cause extraction of a form. The holding member 102 contacts a sensing member to sound a buzzer when the last form is removed from the stack. The mechanism can be rendered ineffective when the machine is turned off or when the device is not correctly attached to the machine.
