Patent GB-1142483-A (GB)
Abstract: 1,142,483. Semi-conductor pulse circuits. ANS Inc. 16 March, 1966 [18 March, 1965], No. 11477/66. Heading H3T. [Also in Division G1] A coincidence gate with input trigger circuits, a linear gate and a " window " type pulse height analyser, for use in a scintillation spectrometry system (see Division G1) are described. Each trigger circuit, Fig. 5 (not shown), has an input capacitor (160) feeding an inverter (161) and includes a tunnel diode (165) biased to its quiescent D.C. condition by an adjustable resistor (167). Resetting of the trigger circuit is by an inductor (166) and diode (168). The coincidence circuit comprises an identical tunnel diode circuit and requires inputs from both the triggers via resistors (201, 202) to switch to its other stable state. The coincidence resolving time of the gate is determined by the biasing resistors of the trigger circuit tunnel diodes (165). The linear gate, shown in Fig. 6, includes a transistor 226 which is cut off when a signal is obtained from the coincidence circuit. This turns on diode 223 which conducts the pulse signals from a logarithmic amplifier through emitter follower 222, to a pedestal remover formed by transistors 233, 234, and then to output capacitor 238. The pulse height analyser of Fig. 7 has a window, the upper (V 2 ) and lower (V 1 ) levels, respectively, of which are set by the bias resistors 301, 302, 306 of comparator 305 and 251, 252, 256 of comparator 255. The comparators pass only signals of amplitude above that set by the resistors. Schmitt triggers 260, 308, convert the amplitude pulses into pulses of width proportional to the input amplitude, which turn shaping flip-flops 261, 309 on and off in accordance with this width. These flipflops connect to different sides of memory flipflop 315. Thus with an input pulse (from the linear gate) less than V 2 , flip-flop 309 will not affect memory flip-flop 315. Flip-flop 261 will cause 315 to change state for a time determined by the input pulse width, producing an output which is coincident with the output from flipflop 261. AND gate 266, responsive only to positive-going pulses, passes the coincident positive pulses (Full line). If, however, the original pulse is greater than V 1  and V 2 , 315 can affect 309 and reset it such that the positivegoing pulses will not be coincident (Dotted line).

Abstract: 1,226,916. Electric meters. C. L. SCHUSKE. Sept.4, 1969, No.43743/69. Heading G1Q. A meter for measuring an alternating current or voltage signal comprises an elongate magnetic core, a coil for inducing flux in the core when energized by the alternating signal and a short circuited conductor, in which current is induced by the flux, mounted for sliding movement on the core in response to the magnetic force between the conductor and the coil, movement continuing until a balance is reached between the force and a gravitational or spring produced opposing force. In one embodiment (Fig. 3) the magnetic core 2 is upright with the coil 5 at the bottom. The structure is enclosed in a transparent housing 8 filled with a damping fluid. A scale 10 is fixed to the core. The short circuited conductor is formed as a hollow ring 7, designed so that its weight is only slightly greater than the weight of fluid which it displaces. The core may be tapered outwardly to provide a linear scale and may have a magnetic return bridge 18 coupling its ends. This instrument must be used vertically, magnetic force on the ring being balanced by gravity. The cavity in the ring may have a flexible diaphragm whereby its volume changes with temperature to compensate for temperature changes of the fluid. In an alternative arrangement, (Fig. 4) an arcuate horizontally disposed rod 22 is used, with the conductive ring mounted on a pointer 31 and biased to a position close to the coil 23 by a spring 34. The weight of the ring should exactly balance the weight of fluid which it displaces. The movable ring may be of aluminium, beryllium or copper. The fluid may be water or alcohol.

Abstract: 1,237,935. Take-up arrangement for looms. MACHINEFABRIEK L. TE STRAKE N.V. 16 Sept., 1968 [15 Sept., 1967], No. 43984/68. Heading DIE. The invention relates to a loom in which the cloth beam (not shown) is pressed against the underside of the sand roller and is frictionally driven by it. Instead of the fabric passing between the sand roller and the beam and winding directly on to the latter, it passes over an auxiliary roller 4 which keeps it in contact with the greater part of the circumference of the sand roller; as shown, the roller 4 has been lowered to enable the fabric 1 to be threaded under the sand roller and over the auxiliary roller 4 at the commencement of weaving, but thereafter the roller 4 is swung upwards about a shaft 6 and kept permanently in contact with the sand roller 3. The cloth beam is urged against the sand roller by a pneumatic jack which allows it to descend as its diameter increases. When it is full, the fabric is cut between the roller 4 and the beam, where upon the air pressure in the jack is released to lower the beam away from the sand roller and enable it to be removed from the loom. Owing to the roller 4 keeping the fabric in contact with the sand roller, weaving continues without loss of tension in the fabric, which merely hangs down from the roller 4 until a sufficient length is available to attach to a fresh cloth beam.

The subject-matter of the Specification is identical to that described in Specification 1,252,448, but the claims are concerned with the feature that, at the bag closing station C at which filled bags D are closed and provided with self-adhesive labels from stationary labelling devices 111, one of the labelling devices at the bag closing station is arranged adhesively to close the bag opening with an applied label. As shown in Fig. 10, self-adhesive labels 113 on two belts wound on drums 112 of two identical sealing and labelling arrangements 111 are each led over a stabilizing roller 114 and round the sharp edge of a plate 115 which successively lifts off the labels. Each label 113  is pressed down on to a bag by a roller 116 to seal a bag flap which has previously been turned over by a curved sealing plate 110, each belt being driven stepwise by drive and pressure rollers 117, 118, and taken up by a roll 119. A printer roll 130 is associated with the second labelling arrangement. A generally similar supplementary labelling device W, which seals a label on to the front of each bag, is mounted on two guide rods 126 and a spindle 127 for transverse adjustment. In order to place the label in the desired position along the bag each bag is drawn forward by a take-over device V by an amount controlled by a time delay unit (t), Fig. 12, not shown.
