Title: Improvements in or relating to printing and other like machines
IPC: B41F13/14
Filed: 1934-07-23
Abstract: 426,910. Printing-machines. ROBINSON, L. T. A., 13, Streatham Place, Brixton, London. July 23, 1934, No. 21515. [Class 100 (ii)] To obtain correct register in rotary printing- machines means are provided to adjust circumferentially the printing or impression cylinders relatively to their shafts while the machine is at rest or in motion, and means may also be provided for similarly adjusting angularly the drive of a printing-couple relatively to another couple so as to register multi-colour or perfected impressions correctly. As shown in Fig. 5, the helical driving-gear 14 of a shaft 30 of an impression or printing cylinder is normally bolted to a disc 18 in which is mounted a worm 19 engaging a wormwheel 20 fitted with a boss screwed to the shaft 30. By loosening the bolts and operating the worm 19 the gear 14 is adjusted relatively to the shaft 30 and the nuts are then tightened after adjustment. To effect a similar adjustment while the machine is in motion a threaded sleeve 36 can be displaced laterally in a threaded bracket 38 which is prevented from rotation by a rod 39 secured to the side frames of the machine. The sleeve 36 is rotated by gearing 34, 35 operated by a shaft 33 fitted with operating handles 32, 321. The motion of the sleeve 36 is transmitted to the helical gear 29 by means of a pair of annular members 42, 44, and lateral displacement of the gear 29 causes circumferential adjustment of the shaft 6 relatively to the shaft 30. The gear 29 fits associated parts including ball bearings 45, 46 can slide on the square end of the shaft 6 on which is mounted the printing or impression cylinder. As shown in Fig. 4, similar adjustments to those described are arranged between a main drive shaft and a rotary couple 1, 2 geared together by wheels 53, 54, so that the impressions from this couple can be registered with impressions from another couple while the machine is in motion or while at rest. In Fig. 5 provision is made whereby the circumferential adjustment may effect the forme cylinder, or the impression cylinder, or both cylinders may be adjusted in opposite directions. If by means of key 56 the gear 5 is keyed to the shaft 6 of the impression cylinder 2 then the forme cylinder 1 is adjustable. If on the other hand the wheel 5 is free on its shaft and a wheel 55 in engagement therewith is keyed to the shaft 30 of the forme cylinder 1 by means of a key 57, then the impression cylinder is adjustable circumferentially. If both gears 5, 55 are keyed to their shafts, then the cylinders 1, 2 are adjusted in opposite directions by operation of either of the mechanisms described.

Abstract: 699,632. Noise-level measurement. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 18, 1949 [Aug. 27, 1948], No. 21538/49. Class 37. [Also in Group XL (a)] The Specification as open to inspection under Sect. 91, comprises a circuit for testing discharge lamps to determine the amount of radio-frequency radiation generated including the lamp 1, to which power is supplied from a source of alternating current comprising the shielded conductors 23 and 24 through a transformer 25 and an inductive ballast 26, a bypassing condenser 27 being connected between one terminal of the lamp 1 and ground intermediate the lamp terminal and the ballast 26 to prevent radio-frequency current from appearing in the ballast or power lines. A resistance 28 is provided in series with the lamp 1 and is connected by a shielded cable to the input circuit of the noise meter 29 and to the input circuit of the radio receiver 30. Headphones are connected to either of the instruments. The audio signal produced is brought to the oscilloscope 31 through a condenser 32 where it is seen as short-duration pulses superimposed on the lamp current wave shape. The noise meter 29 shows the microvolt magnitude of the radio frequency picked up. An electronic switch 33 is employed to show alternately lamp voltage and the audio-pulsed current wave shape, so that lamp current, lamp voltage and the radio noise generated by the lamp 1 are seen at the same instant on the screen of the oscilloscope. This subject matter does not appear in the Specification as accepted.

Classes 23 and 82(ii) In a process for classifying fine magnetized particles, a liquid suspension of the particles is passed through a hydrocyclone or vortex chamber to prevent or eliminate agglomeration. The process may be used in the production of a suspension to separate out oversize particles received from a grinding mill for return to the mill. As shown, a suitable hydrocyclone has a casing consisting of a conical part 9 and a cylindrical part 8, the inlet pipe 6 opening tangentially into the cylindrical part. Coarse particles leave by the apex aperture 12 and fine particles through a cylindrical pipe 11 coaxial with the cylindrical part 8 and extending some distance into the cyclone. The hydrocyclone may have a diameter of 35, cm. and operate at a feed pressure of 0.5 atmospheres.

Abstract: 772,102. Electric digital-data-storage apparatus. LABORATORY FOR ELECTRONICS, Inc. July 26, 1955 [Aug. 9, 1954], No. 21589/55. Class 106 (1). Apparatus for interpreting a train of electrical data signals each having two portions, comprises means for obtaining a version of the signal train delayed by a period substantially equivalent to the duration of one of the signal portions, means for combining the original and delayed signal trains to derive a difference signal train, a source of timing signals, and means for associating the difference signal with the timing train to obtain electrical pulses corresponding to the data. To allow close packing of return-to-zero type binary signals on a magnetic drum, for example, without leading to false read-out as indicated in Fig. 1 (d) (note the false result derived from the last-but-one binary digit), the output waveform from the read head 12 (e1) is fed via an amplifier 13 to the grid 15 of a differential amplifier 14, and also, via a delay T circuit 16 of - (e2) (see Fig. 1 (c)) to the other 2 grid 21. The outputs from the anode 22 (e2-e1) and the anode 26 (e1-e2) are fed to coincidence gates A and B respectively which are controlled by clock pulses, Fig. 1 (b) from a source 24. The correct binary digits appear at terminals 25 and 31.

[Class 132 (iii)] [See also Group XXXVIII] A stuffed doll or toy animal has incorporated with it a miniature gramophone provided with means for resetting the reproducer on the record disc and for retaining the reproducer on the record disc during playing. In the construction shown in Figs. 1, 2 and 3 the doll is filled with hair, fibre, kapok, or wood-wool and is fitted with a gramophone provided with a reset control lever 5 rotatably and slidably mounted in a bracket 6, the inner end of the lever 5 being cranked and pivotally connected at 8 to the reproducer 2 carried by the tone arm 9 so that when the lever 5 is turned slightly it lifts the reproducer from the record disc and when the lever is pushed back into the body of the doll it enables the reproducer to be reset to the starting point on the record disc. A sapphire or other hard-pointed needle 1 is fitted to the reproducer 2 to eliminate changing of needles. A spring 10 connects the tone arm 9 to the base of the gramophone to enable the doll to be held in any position without slipping of the reproducer 2. When playing of the gramophone is not required the needle 1 can be inserted in a round wire slot or socket 11 in a wire stay 12 by turning the control lever 5 slightly to lift the reproducer 2 and pulling it outwards so that it is brought immediately above the socket 11. The usual stop catch and speed regulator 3 and spring winding lever 4 are fitted to the gramophone so as to be operated from the back of the doll. The lever 5 may be provided with an elbow which enables the lever to be bent downwards parallel with the body of the doll to permit throwing about of the doll without causing damage to the gramophone. The gramophone is enclosed in wire netting 14 and is carried by a circular metal base 15 and overall is fitted a linen cloth to keep out dust.
