Title: Improvements in or relating to tobacco manipulating machines
IPC: A24C5/18
Filed: 1934-03-23
Abstract: 440,182. Packeting-machines. MOLINS, W. E., 2, Evelyn Street, Deptford, London. March 23, 1934, No. 9147. [Class 94 (i)] [See also Group VI] A continuous rod or filler of tobacco for making cigarettes, or for cutting into sections for insertion into packages, is made by feeding the tobacco through a confining passage which determines the cross-sectional area of the filler, and removing the tobacco from the opposite end of the passage continuously and at a slower speed than that at which it is fed into the passage, so that the tobacco is compacted within the passage and is raised or formed to a crosssectional size which is at least equal to the minimum cross-section of the passage. Fig. 1 shows a conveyer band 1 receiving tobacco from feeding-apparatus 16 and moving the same along a trough 7 under rollers 8, 9 and on to a bridge piece 2, which leads to a second conveyer device 3, for example, a continuous paper web, which moves at a less velocity than the band 1. At the same time, the stream of tobacco is confined by side walls 10 and guides 11, together with a member 6 adjustably connected to a frame 62 so as to rest on top of the tobacco. The frame 62 is pivoted at 65 and also carries the roller 9. The tobacco may then pass under a compression roller 14 adjustable at 67, and the usual tongue 17. The side walls 10 preferably have a slight divergence to prevent choking or jamming of the tobacco, but the top wall 6 may slope downwards slightly. The rollers 8, 9 may be replaced by a rail engaging the top of the tobacco. Specification 441,402 is referred to.

Abstract: 610,115. Printing-machines. ETABLISSE MENTS SCHAEFFER & CIE. March 25, 1946, No. 9214. Convention date, Feb. 16. [Class 100(ii)] The printing-rollers 1, 2, 3 of a multicolour fabric-printing machine are driven from a corresponding number of gear wheels 23 arranged in a casing 9 offset from the frame 7 of the machine in which bearings 8 for the rollers are mounted, and motion is transmitted from shafts 32 of the wheels 23 by means of universal joints 24, 25 and telescopic shafts 26 having one portion of square section slidable in the other. Axial adjustment of the rollers is thus permissible. The wheels 23 are all geared to a common gear 22 driven by gearing from a pulley 14. A detachable coupling connects the shaft of each printing-roller to the universal coupling 25, so that any roller can be disconnected from its drive. To ensure correct register a box-wheel adjustment as shown in Fig. 8 is arranged between each wheel 23 and its shaft 32, and by means of wheels 1<1>; 2<1>, 3<1>, 4<1>, 5<1>, 6' arranged in front of the casing 9 circumferential adjustments can be made between the wheels 23 and the driving shafts of the printing- wheels. Indicators and scales are used to control the adjustments. The box-wheels comprise worms 35 the bearings of which are secured to the wheels 23, and worm wheels 34 on the shafts 32. Each worm gearing is arranged in a casing 33 in which is mounted wheels 37, 38 geared to the worm 35. The wheel 38 has teeth 48 which engage circular teeth 39a of a rack 39. which is normally stationary, but each rack can be given a sliding movement by operation of one of the wheels 1<1>-6<1>, and sliding movement of the rack rotates gear 38 and causes rotation of the worm 35 and circumferential adjustment of its shaft 32 relatively to wheel 23.

Title: Improvements in and relating to Pigment or "Carbon" Printing by Silver.
Inventor: MIDDLETON THOMAS PERCY
IPC: G03C11/12
Filed: 1918-06-05
Abstract: 127,953. Middleton, T. P. June 5, 1918. Carbon, pigment, and like processes; films, stripping; plates, films, and papers; developing.- For the production of pigment and similar prints from a silver image, a pigmented or dyed silver emulsion is very thinly coated on to a support which allows the silver image to be developed and fixed on the original support. After washing, transfer is effected to a support (temporary or final), and the film allowed to dry prior to the removal of the original support and subsequent bleaching treatment. Supports are used which allow dry-stripping, or in which the image film is released by alcohol or a suitable solvent; but soaking in hot or cold water is not used. For the support, 'baryta paper is coated with a solution of wax or of wax and rubber in xylene, and, when dry, is re-coated with a solution of gum sandarach in alcohol. A developer, such as amidol or glycin, is used which has little or no tanning action on the gelatine, and a slightly acid fixing-bath is used which includes boric acid. The print is transferred to an ordinary piece of single transfer paper as in carbon printing, and, when dry, the original support is stripped. For double transfer, a temporary support is prepared with a solution of caoutchouc, gum elemi, and gum damar in benzene. The transferred image is treated with a bleaching-solution containing chromic acid, copper sulphate, and potassium bromide, and afterwards placed in warm water and developed as in carbon printing. A soup of fine boxwood or sawdust may be used as in the Artigue process. The silver bromide left may be removed or redeveloped. The process may be modified to produce clear gelatine images for colour printing, and a dye or pigment used which washes out during subsequent treatment. Specifications 1436/81. 28415/07, and 20555/12 are referred to.

Title: Feeding device for magnetic tape or wire
IPC: G11B5/48
Filed: 1963-03-08
Abstract: 957,157. Feeding webs. STANDARD TELEPHONES & CABLES Ltd. March 8, 1963 [March 15, 1962], No. 9308/63. Heading B6B. [Also in Divisions D1 and H2] The tension of magnetic or printed tape fed from one reel 2 to another, via reading and writing heads on plate 1 and storage containers 3, is maintained substantially constant by means of an eddy-current coupling whose working gap is increased automatically to relieve excess torque. The tape is fed to or from the storage reels (which are driven at constant speed) over a tensioning roller 5, against which it is pressed by an idler roller 6. The coupling comprises a ring of magnets 15 driven at constant speed by means of a pulley 14 and exerting a torque on an eddy-current disc 10 coupled to the roller 5 dependent on the slip. If this becomes excessive, the disc rides on cam-rollers 18, against spring 17, to increase the gap and reduce the torque. The rollers 5 may rotate in the same direction as the pulley 14 for drawing tape off the reel, or in the opposite direction for controlling the tension of tape drawn on to a reel, the coupling then acting as a tensioning brake.

Title: Methods of and systems for effecting the non-destructive analysis of materials
IPC: G01N29/38
Filed: 1966-03-03
Abstract: 1,141,523. Ultrasonic inspection devices. INTERNATIONAL HARVESTER CO. 3 March, 1966 [17 March, 1965], No. 9322/66. Heading H4D. In an ultrasonic pulse-echo system for determining the size distribution of discontinuities in a medium (e.g. steel or aluminium) the amplitudes of received echo signals are compensated for attenuation within the medium to provide signals, indicative of discontinuity size, which are stored and subsequently sampled and converted to an output signal that is statistically indicative of the size distribution. In the embodiment of Fig. 2, piezoelectric transmitting/receiving transducers 26 coupled through liquid couplant 15 to a specimen S moving relative to the transducers are sequentially energized in successive pulse repetition periods. In a particular pulse repetition period, echo pulses received by whichever transducer 26 is in use are passed to receiver-amplifier 28 whose gain is time-varied to compensate for increased attenuation with echo time. Analogue signals corresponding to the compensated amplitudes of echoes received from discontinuities located at different depths in the specimen S are provided by and stored in respective time-gating circuits 31. The analogue signals are sequentially sampled (at the ultrasonic pulse repetition rate or higher) after all those resulting from a single transmitted ultrasonic pulse have been stored, e.g. at the end of the pulse repetition period, and are read out to circuitry 17. The transmission of the succeeding ultrasonic pulse may be inhibited until the sampling operation has been completed. Circuitry 17 (comprising a conventional analogue computer, or an exponential amplifier 30, integrator 35, difference amplifier 36 and reference source 38) appropriately weights and integrates the analogue signals obtained during the entire scan of the specimen S and compares the result of this analysis with preestablished reference data (e.g. from the microscopic analysis of a reference specimen), thus providing a basis for automatic grading (by device 37) of the specimen S.

Title: Improvements in or relating to the Control of Combined Engines and Electric Generators.
IPC: H05B31/00
Filed: 1917-06-30
Abstract: 116,941. Stevens, W. A., and Sankey & Sons, J. June 30,1917. Dynamos, regulating.-The output of a generator, driven by a steam-engine or an internal-combustion engine, is controlled between maximum and minimum values by subjecting the valve (or its equivalent) that controls the supply of power to the engine to two forces acting in opposite directions and adapted to move the valve between two limiting positions, determined by stops and corresponding to the maximum and minimum outputs, one of such forces being an electro-magnetic force brought into action upon variation in the condition of working. The invention is particularly applicable for supplying current to a search-light m provided with a shutter n, the current through the arc being reduced when the shutter is closed. The valve a controlling the supply of fuel to the engine is connected by links d, e to a controlling-spring j and the core h of a solenoid i bridged across the leads r, r<1> from the dynamo c by the movement of the switch t, which is closed when the shutters n are closed, thus reducing the speed of the engine and the output of the generator. The solenoid i is also energized by a relay w when the generator voltage exceeds a predetermined maximum. Adjustable stops s, s<1> limit the movement of the valve a. Alternative arrangements are described in which the functions of the spring j and the solenoid i are reversed, the solenoid opening the valve a when energized.
