IPC: B65H33/12

Abstract: 1,253,140. Stacking articles; delivering sheets. HENRY SIMON Ltd. 29 June, 1970 [24 July, 1969], No. 37202/69. Headings B8C and B8R. A method of forming a stack of cases from a moving line of cases in shingled configuration, comprises the steps of providing means to engage the trailing edge of a ease in the line and progressing the means forwardly at a speed greater than the speed of movement of the line so that successive trailing edges are in turn engaged by the means whereby that portion of the line forward of the first mentioned trailing edge is gathered to form a stack of horizontal superimposed cases. As shown, a line of collapsed cases L is fed by a conveyer C at the output stage of a case making machine, to spaced conveyer belts 10, beneath which at opposite sides thereof are located pairs of chain drives 12, 16 all driven simultaneously and carrying arms which can move through spaces between the belts 10 and which are secured to bars 23, 24. A door 26 forms an abutment for. the forward end of the line of cases and is heldclosed by a magnetic catch. 28. The arrangement is such that as the arms 25 are moved by the chain drives 12, 16 from the Fig. 1 position through the Fig. 3 position to the Fig. 4 position a predetermined number of cases are stacked against the door 26. Further movement of the arms pushes the stack beyond the door against the holding force of the catch 28 and the arms then descend through the slots between the belts and return to the starting position. The number of cases in each stack is determined by a counting device 29. In another arrangement, Figs. 5-7 (not shown), L-shaped members carried by a chain drive at each side of the machine have one of their arms guided in tracks, to raise the other arm to move relative to and upwardly through the spaces between the belts. At the discharge end of the machine a restraining device is raised by the first stack passing through the machine, the stack being subsequently pushed onwards by the succeeding stack.

Abstract: 1289568 Measuring current; analogue to digital converters. SIEMENS AG 17 Sept 1970 [30 Oct 1969] 44352/70 Heading G4H Apparatus for measuring alternating current in an h.t. conductor H comprises a source of light L1, preferably a laser, and a modulator Ml comprising a Tamin or Mach-Zehnder interferometer, wherein the light input beam LS1 is broken into two coherent beams, one of which is passed through a crystal element which element displays a change in refractive index in proportion to an applied field the field being either magnetic and produced directly by current in the conductor H, or being electric and produced by a voltage U1 proportional to the current via a current/voltage transformer W1, the beams being recombined to yield interference fringes moving across an optical system, the output from which is conveyed via two light 'conductors LL2<SP>1</SP>, LL2<SP>11</SP> to two photo-electric elements Ph11, Ph12, electrical impulses from which are counted at Z1. The light conductors are adapted so that they darken completely upon the passage of a dark pulse and are phase displaced so that they and hence the photo - electric elements receive the pulses in turn, the output of the transducers Ph11, Ph12 being connected to the counter Z1 via a trigger circuit K so that if the current in the conductor H is rising and the fringes are moving in one direction, one of the conductors LL2<SP>1</SP> ,  LL2<SP>11</SP> will receive a dark pulse first and set the trigger to cause the counter 21 to count forwards Upon the reversal of the current flow, the other conductor will receive the dark pulse first and trigger the counter to count in the opposite direction. In a modification, Fig. 3 (not shown), two modulators (MO21), (MO22) are used and the voltage (U2) corresponding to the current to be analysed is rectified at (G) so that each of the modulators works from positive or negative half cycles only, four light conductors and transducers being employed and counting effected at (Z2) via a circuit (V) adapted to trigger the mode of the counter and reset on each zero passage, the light source being split into two beams at St.

Abstract: 1290192 Knitting-machines M PHILIP 10 Dec 1969 [12 Dec 1968] 60274/69 Heading D1C In a cylinder and dial interlock machine one or both (as shown) needle bed(s) is/are provided with sets of long and short needles actuated by different cam tracks 10, 10'; 26, 26'. The sets of needles in the one bed and corresponding needles in the other co-operate to knit alternate courses. The dial needles are delayed while moving to the cast off position, where they have passed the back of and cleared the adjacent cylinder needle. Thus the dial needles do not interfere with the operation of the intermeshing cylinder needles which can begin to rise in their cycle for knitting the next course. Thus the long and short dial needles are delayed between G2, H2 and L1, M1 in their respective tracks, at which time the short and long cylinder needles respectively begin to rise up cams 18, 18'.

Abstract: 1296230 Converting GENERAL ELECTRIC CO 12 Jan 1970 [10 Jan 1969] 1341/70 Heading H2F An inverter or frequency changer, e.g. for supplying power to an induction heater comprises a plurality of main converting elements (Fig. 1, not shown) connectable between polyphase AC terminals on the one hand and single phase (or D.C.) terminals on the other and having first and second means for deriving signals representative of the duration of inverse voltages across at least two of said main elements. As shown in Fig. 2, thyristors 31 ... 35 are forward biased when the difference between respective ones of the polyphase line voltages A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP> and the voltage between one of the single phase (or D.C.) terminals P and neutral is positive. These signals are provided by potential transformers 21 ... 24. Thyristors 32 ... 36 are similarly forward biased by appropriate phase relationship between single phase terminal N and the polyphase line voltages. Each thyristor 31 ... 36 is triggered (Fig. 3, not shown) at a time corresponding to the turn-on of one of the six main elements, after appropriate delay, if necessary. The turning off of the respective thyristors 31 ... 36 is shown to occur at the end of the period of reverse bias of the appropriate main element. The current through resistor 26 is thus shown to be sequencies of six pulses, each pulse corresponding to the margin angle period of a respective main converting element. These pulses are clipped by a transistor circuit 20. Fig. 3 (not shown) relates to a system of pulse stretchers and thyristors, responsive to the trigger pulses of the main thyristors and to the triple-frequency current detected by current transformer 43 for providing appropriate turn-on pulses for thyristors 31 ... 36. Alternatively, thyristors 31 ... 36 may be replaced by diodes.
