Title: Method of and apparatus for rejecting faulty sheets, or groups of sheets, of paper, cardboard and the like
IPC: B07C5/36
Filed: 1965-06-18
Abstract: 1,080,404. Sheet delivering apparatus. JAGENBERG-WERKE A.G. June 18, 1965 [July 17, 1964], No. 25850/65. Heading B6H. In a method of rejection of faulty sheets cut from a web 20 advanced by feed rollers 22 to a transverse cutter 23 the faulty sheet sections are detected on the moving web by a capacitor 27, the variation of capacitance producing a pulse which on amplification in an amplifier 29 is stored in a shift store 31. The pulse activates an impulse transmitter 33 coupled to the control speed of the web 20 and transmits regular pulses through the amplifier to advance the pulse through the shift store in accordance with the speed of the web. A switch arm 36 in a sheet size adjuster 35, having a number of contacts 0<SP>1</SP>-18<SP>1</SP> corresponding to the units of lengths of the sheets, is preset to the length of the sheets cut and determines the number of shifts in the store, whereupon the pulse is applied to a scanning store 38. The scanning store also receives a pulse from a scanning member 40 of each cut of the transverse cutter 23. On coincidence of signals from the sheet size adjuster 35 and the scanning member 40 in the scanning store 38 the latter produces an output signal - which actuates off counter 42 which through pre-selection switches I . . . III, corresponding to a single, double or plural sheet ejection, respectively, energizes an electromagnet to deflect a rejection plate 24, which causes the faulty sheet or sheets to be stacked on the stack 26.

Title: Improved fork-lift truck with swinging mast
Inventor: TAYLOR JAMES WILLIAM HENRY
IPC: B66F9/10
Filed: 1967-06-05
Abstract: 1,206,962. Masted lift trucks, MATBRO Ltd. 5 June, 1968 [5 June, 1967], No. 25923/67. Heading B8H. The mast structure 12 of a lift truck is mounted for swivelling about a vertical axis offset to one side of the fore-and-aft extending centre-line of the truck, between a forwardly facing and a sideways facing position, such that in both positions, the centre of gravity of a load carried by the mast is disposed substantially on the said centre-line. The mast structure 12 is mounted for tilting in a vertical plane on cheeks 5 of a gate member 1 which is pivotable about a vertical post structure 1a, a roller 9 on the gate being always supported on an arcuate track 10 mounted on the truck frame. The gate member 1 is pivoted about post 1a by a jack 4 and the mast 12 is tiltable by a pair of jacks 7 on the member 1. The mast structure 12 comprises an inner fixed frame pivoted at its base to the cheeks 5 and an outer frame vertically slidable relative to the fixed frame by actuation of an hydraulic ram. The gate and mast structure are arranged on the truck with the base of the fixed frame and the track 10 for the gate member just above the level of the top of the truck front wheels, between which the gate member is situated. The sliding frame in its lowered position extends below the fixed frame such that a carriage thereon can be placed adjacent the ground, the carriage being vertically slidable on the movable frame. In operation, a load is picked up by the carriage while it faces forwardly, and raised to a level just above the top of the truck front wheels, whereupon the mast structure is slewed into the sideways position and the load is lowered on to the truck frame between the front wheels.

Title: Constant-voltage circuit
IPC: H04N3/185
Filed: 1974-06-11
Abstract: 1474071 Automatic voltage control HITACHI Ltd 11 June 1974 [13 June 1973] 25932/74 Heading G3R A power supply circuit, suitable for construction as an integrated circuit in a television receiver, includes a series transistor controlled by a drive transistor in response to a control signal from an output voltage sensing and error amplifying circuit. One electrode of the drive transistor is connected to the output terminal of the series transistor through a constant voltage element so as to minimize the voltage drop across the series transistor at the operating threshold of the circuit. As shown, a transistor 3 is biased by an output voltage divider 4, 5, 6 and a Zener diode 7 so as to produce an amplified error signal which is fed to the base of a drive transistor 2 which in turn controls the conduction of a series transistor 1 in order to regulate the output voltage V 0 . The collector of transistor 2 is connected to output terminal 13 by diodes 17, 18 connected in the forward direction, so that the junction of the collector of transistor 2 and a resistor 15 is maintained at a fixed voltage below the collector voltage of the series transistor 1. In this way, the lower limit of circuit operation occurs when transistor 1 saturates, minimizing the voltage drop between input terminal 11 and output terminal 13. A similar embodiment, using transistors of opposite conductivity types, is described with reference to Fig.4 (not shown).

The lip 28, Fig. 1, of the insole may be cemented down or left loose to increase the flexibility. After the levelling operation, the surface of the insole adjacent the upper and the edge face of the shoe upper may be lightly buffed as distinct from the usual roughening operation employed in cement sole attaching processes, or this may be omitted, pyroxlin cement is applied to the margin of the upper inside the line of stitches and the margin of the insole, and also to the margin of the sole without extending to the extreme edge thereof and the sole attached, e.g. as in the machine described in Specification 339,739, [Class 17 (i)].

Title: Improvements in or relating to circular-knit fabric
Inventor: MUNDEN DENNIS LAWRENCE
IPC: D04B15/48
Filed: 1957-08-24
Abstract: 909,071. Knitting. HOSIERY & ALLIED TRADES RESEARCH ASSOCIATED. Nov. 24, 1958 [Aug. 24, 1957], No. 26776/57. Class 74 (2). Stretch yarn on its way to the needles of a circular knitting-machine, to be knitted into stitch loops thereby, is substantially straightened by drawing it from a supply, under appropriate tension, by means of an absolutely positive feed device which is driven at a predetermined speed relatively to the machine speed and is surrendered by the device to the needles. The tension is imposed by a tensioning device between supply and positive feed device. The stitch cams are so set that the surrendered yarn is at a tension lower than that between the two devices. Thus may be achieved a substantially constant ratio of straightened yarn feed speed to machine speed and so a uniform quality of fabric. For shaping purposes, however, the positive feed may be controllable to effect variation in rate of forwarding of yarn. It may consist of a pair of nip rollers one driven by the machine; or it may be a single positively driven roller over which the yarn extends a plurality of times, being prevented from screwing itself along the roller by suitable guiding means such as a pig-tail or helix extending substantially parallel to the roller axis and around which and the roller the yarn is taken a plurality of times; or it may be an endless band running over guide rollers and co-operating with part of the periphery of a single driven roller, the yarn being engaged between roller periphery and apron.
