Title: Improvements in automatic bobbin-changing looms
IPC: D03D45/50
Filed: 1963-06-19
Abstract: 1,026,475. Automatic bobbin-changing looms. FISCHER A.G.GEORG BRUGG. June 19, 1963 [Aug. 9, 1962], No. 24470/63. Heading D1E. The old and new weft trails are disposed of by suction generated by injector action of compressed air in a nozzle 57, Fig. 4. Prior to initiation of a bobbin-changing operation, the weft end of the next bobbin in the magazine, previously taken by a tip bunch stripper and deposited in a suction pipe 19, extends into a pipe 24 leading to a waste box, and is clamped against the conical mouth of the pipe by a head 55 carried by a piston 51 loaded by a spring 52. The old weft trail of the bobbin ejected on the preceding replenishing operation has been sucked into a pipe 23 but its other end is still held by a combined cutter and clamp situated at the position occupied by the shuttle eye when the shuttle is boxed. When the next bobbin change commences, the cutter and clamp opens to release the weft trail and closed cut and clamp the weft of the spent bobbin in the shuttle. Compressed air is admitted at a pipe 14 to retract the piston 51 and thereby uncover a port 59 in the piston rod, so that air flows from the nozzle 57 to the pipe 24, thus creating suction in the pipes 19, 23. The old weft trail in the pipe 23 is discharged to the waste box through the pipe 24; although the weft end of the fresh bobbin which has now been inserted into the shuttle is no longer clamped by the head 55, it is held by the air flow until the shuttle has laid the first pick from the fresh bobbin. When the weft trails of the fresh and spent bobbins are cut at the selvedge, the weft trail of the spent bobbin, which is held at one end by the shuttle eye cutter and clamp, is drawn into the pipe 23, the mouth of which is adjacent the cutter and clamp on the side nearer the fabric; the fresh weft trail in the pipe 19 is discharged through the pipe 24. Meanwhile, the tip bunch stripper has operated on the next bobbin in the magazine and deposited its tip bunch in the pipe 19; the weft extends into the pipe 24 and is clamped by the head 55 when the air supply at the inlet 14 is cut off. Various air valves, as well as the tip bunch stripper and a flap controlling descent of the bobbins in the magazine, are operated by pneumatic cylinders, the operations being initially triggered by the bobbin transfer hammer.

Title: Improvements in or relating to blankets for printing machines
IPC: B41N10/04
Filed: 1933-09-06
Abstract: A printers' blanket is made by impregnating a woven or felted woollen base with an ink or oil resisting composition consisting of nitrocellulose or other cellulose ester, cellulose ether, or other synthetic plastic, dissolved in a preferably volatile solvent.  The impregnation is effected by drawing the material across a suction-box, or by soaking, after which the material is cut into appropriate lengths.  Alternatively, impregnation may be effected during the formation of the material.  The impregnation may be through the whole body of the blanket, but preferably extends to less than a quarter of its thickness, and leaves a resilient surface, which may be ground to the desired smoothness.

[Also in Division H1] A flasher unit of the type wherein a movable contact 4, Fig. 3, is held away from a fixed contact 5 by a thermally expansible wire 6 and is magnetically attracted towards the fixed contact by current flowing through a coil, is characterized in that the coil is divided into a plurality of windings so that the flash rate can be adjusted. In Fig. 3 the coil comprises two windings 2a and 2b both of which are in circuit when the flasher is controlling vehicle turn indicating lamps 11 and 12. When additional trailer lamps 16 and 17 are connected by means of plug and socket 22, a relay 24 is operated to cut out winding 2b so that the flash rate remains the same. In a modification (Fig. 4, not shown) winding 2b is short-circuited when not in use. In another arrangement (Fig. 2, not shown) the relay 24 is replaced by a manually operable switch. A step switch may be provided for varying the number of turns in the coil winding so that the flash rate can be varied with a constant load.

Filed: 1936-09-15
Abstract: 483,732. Impedance networks. PERCIVAL, W. S. Sept. 15, 1936, No. 25095. [Classes 40 (iii) and 40 (v)] In an intervalve coupling for the intermediate-frequency amplifier of a superheterodyne television receiver, in which the interelectrode capacities 2C of the two valves form part of a band-pass filter, the effect of the earth capacity and the self-capacity of an inductance coil is compensated, and the need for using large coils is obviated, by arranging the coils to form an autotransformer. In a known arrangement. Fig 2, the filter, which is terminated at one end by a resistance R and at the other by the grid circuit of valve 2, comprises a half-section with a series arm L2, C2 and a shunt arm made up of inductance L1 and the intervalve capacities 2C, the two arms being tuned to the midband frequency, or so as to bracket the midband frequency closely, while the impedance of the shunt arm has the value appropriate to a full section instead of a half-section as described in. Specification 475,490. The invention consists in connecting the condenser C2 to a tapping on coil L1, Fig. 3, so that part or all of the inductance L2 may be replaced by the leakage inductance of the autotransformer L1. In this way the earth capacity of coil L2, which tends to narrow the pass band, and its self-capacity are eliminated or reduced ; the capacity C2 is correspondingly increased. In a modification, Fig. 4 (not shown), the resistance R is shunted by a reactance network forming an m-derived termination.

Abstract: 591,130. Radiolocation. WATT, R. A. W. Sept. 15, 1938, No. 25133. [Class 40 (v)] A cathode-ray tube is used for the measurement of the time interval between the emission of a radio signal at the locating-station and the receipt of a re-radiated signal .from the target or object to be located. The target carries a receiver responsive to signals, e;g. pulses, from the locating-station, and a transmitter for emitting signals on the same, a related, or an unrelated radio frequency and stimulated by the receipt of a signal. The signal from the locating station may be a single-pulse or a sequence of pulses of regular or irregular recurrence frequency. Means may be provided for restricting the solid angle utilised by the radiation emitted by the sender or accepted by the receiver at the locating-station ; and the direction of the target may be ascertained by measurement of angles of azimuth and altitude, e.g. as described in. Specification 252,263, [Class 40 (v)]. The signals from either station may have a special form for restricted response or for identification. The CR tube at the locating station indicates on a calibrated time scale both the emitter pulse or signal and the secondary pulse or signal from the target. The time base may be released by the emitted pulse and may be synchronized to a series of recurrent pulses. The receiver of the re-radiated signals is preferably at a short distance from the sender of the locating- station.
