Title: Improvements in photographic stencils
IPC: G03F7/06
Filed: 1944-01-31
Abstract: 571,107. Photographic wash-out reliefs; photo - mechanical printing surfaces. KODAK, Ltd., and STEVENS, G. W. W. Jan. 31, 1944, No. 1795. [Class 98 (ii)] In the preparation of a photographic stencil forming a etching resist, a silver salt emulsion layer is subjected to at least two separate image development steps and to at least two separate steps for imagewise removal of the layer. An image-development step may be performed simultaneously with an imagewise removal step. Two or more latent images may be printed into the layer before any one is developed or firstly one can be printed and developed and subsequently another can be printed and developed. With two images, one image may be developed and the layer removed imagewise and then a second image may be developed and the layer again removed imagewise, or the images ma.y be successively developed and then the layer successively removed imagewise. A developing solution comprising hydroquinone, potassium metabisulphate, potassium bromide, potassium hydroxide, and water used at 100-120‹ F. develops the exposed parts of the emulsion rapidly, tans the gelatine at those parts, and washes out the unexposed parts. In example 1, a silver-plated copper plate coated with an unhardened process-type gelatino-silver halide emulsion is exposed to a positive of an image to be deeply etched and is developed in non- tanning developer. The image is treated in a bleach-hardening bath, the unhardened gelatine is washed out in hot water, and the layer is dried in non-actinic light. The plate is etched deeply with alcoholic ferric nitrate and is washed. The emulsion is exposed to a negative image of the fine detail image, is developed to give a gelatine stencil containing a silver image, is treated in an etch-bleaching bath to imagewise remove the gelatine layer, and a shallow etching treatment is applied. In example 2, a glass plate coated with a hardened processtype emulsion is exposed to a negative image of the image to be deeply etched, is developed, washed, and treated in an etch-bleach bath. After washing, the layer is re-exposed to a negative image of the second desired image, is developed, dried, re-swollen in a solution of a loading agent, e.g. a 20 per cent aqueous solution of sugar or glycerine, the glass etched by sand-blasting, the layer washed, the second image etched from the layer by an etch-bleach bath, the layer retreated with a solution of a loading agent, and the glass given a further light sand-blasting. The cycle of operations may be repeated by washing, bleaching, washing, re-exposing, developing, and etch-bleaching. In example 3, a surface coated with unhardened emulsion is exposed, developed, treated in a bleach-hardening bath, re-exposed to the second image, developed in a non-tanning developer, the unhardened gelatine washed out to give a stencil of the first image only, the second image treated with an etch-bleaching bath, and the surface etched. The surface could also be partially etched between the two imagewise removal steps.

Abstract: 492,744. Electricity supply. STEVENS, S. A., and WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Jan. 22, 1937, No. 1977. [Class 38 (iv)] Selecting sources in service.-In a supply system comprising a number of rectifiers supplying load circuits, each of constant value, in which each of a number of load circuits to be simultaneously energized is supplied from a separate rectifier or rectifier group, the capacity of which is not substantially greater than the load of the circuit, each of the rectifiers is arranged to be interchangeably connected to a single one or other of a number of the loads in such manner that at least one spare rectifier is always available during any normal load condition. As applied to arc projection apparatus in kinema equipment, three projectors P1-P3, two spot-lights S1, S2 and a slide lantern L are supplied from five rectifiers R1-R5 over a system of bus-bars to which the various loads may be connected selectively at any of the points 1-21. The projectors may require 150 amps. and the other lamps 75 amps., whilst each of the rectifiers has a capacity of 75 amps. The arrangement is such that for any load other than the peak load during transition periods which consists of one projector, two spot-lights and the lantern, one spare rectifier is always available. Contactors at the points such as 4, 7, 11, 15 on each rectifier bus-bar, are controlled by coils such as 22-25, Fig. 2, which are supplied from bus-bars C1, C2 provided with interlock contacts 28-35 so arranged that when one of the contactors is energized by closure of a switch 36-39 to energize a particular load, the contacts 28, 32 also controlled by the corresponding coil, e.g. 22, are opened and no further load can be connected to the rectifier bus as long as it is loaded. The opening of any pair of contacts 28, 32, &c. de-energizes pilot lamps 40 to indicate that the rectifier not available for further loading. The arrangement is such that whilst a rectifier is supplying a load its control circuits may be prepared by closing another of switches 36-39 so that it will supply another load circuit as soon as it becomes available when the load being supplied is switched off.

Abstract: 1340252 Gas discharge display panels BURROUGHS CORP 15 Jan 1971 [29 Jan 1970 (3)] 2076/71 Heading H1D A display panel 10 comprises an insulating gas-filled envelope including a plurality of gasfilled cells, an anode electrode 110 and a cathode electrode 160 associated with each cell, and a source 115 of excited particles in a chamber 114 in said envelope remote from said cells and communicating from said chamber through gas communication paths with said cells, said source comprising an electrode which is adversely affected by high temperatures such as those at which the envelope is formed, said source being sealed in said chamber by means of a sealing material 119 which forms an hermetic seal with said envelope at about room temperature. The panel includes a bottom plate 20 of glass or ceramic having a plurality of rests 90. Counting or scanning anode wires 110 are secured in slots 90B to 90D by glass frit. Alternatively these electrodes may be heated, evaporated or otherwise formed in the rests. Auxiliary anode wires 120 extend along slots 90A and 90E to positions where these slots are blocked by masses 93 of glass frit. A centre plate 130 has a plurality of slots 150 and a plurality of apertures 144 forming columns aligned with apertures in scanning cathode electrode strips 160A to 160D seated in slots 150C to 150F, and rows aligned with slots 90B to 90D in plate 20. Keep-alive cathode strip electrodes 167 and 168 are seated in slot 150A, and a narrow reset cathode strip 164 is located in slot 150B. Display anode wires 180 are seated on the top surface of plate 130 or in slots in this surface or in slots in the bottom surface of a transparent cover plate 190. The plates 20, 130 and 190 are sealed together at their peripheries by glass frit and the enclosure so formed is filled with Ne, A, Xe or a mixture thereof to which Hg vapour is usually added to minimize cathode sputtering. An auxiliary keep-alive cell 114 (Fig. 3) in plate 20 in communication with slot 150A through a small hole 112 contains an electrode 115 comprising a radio-active material such as tritium carried on a solid support and is sealed by a mass 119 of a gallium alloy. Alternatively (Fig. 11, not shown) the cell 114 may contain two electrodes to fire the gas in the cell and provide excited particles. In either arrangement the cell may be elongated to enable the structure 115 or the electrodes to be offset from the hole 112 (Figs 4 and 12, not shown). The panel thus provides a lower layer of counting or scanning cells in communication with an upper layer of display cells. Reset cathode 164 forms part of a column of reset cells in communication with the first column of counting cells. Keep-alive cathodes 167 and 168 form part of keep-alive cells provided to ensure firing of the reset cells. Auxiliary keep-alive cell 114 provides excited particles to the reset cells through slot 150A and slots 90. The keep-alive cells are held ON continually.

Abstract: 1,171,821. Constant tension winches. FRIEDRICH KOCKS G.m.b.H. 13 Jan., 1967 [13 Jan., 1966], No. 2080/67. Heading B8B. A warping and holding winch for ships providing adjustable, substantially constant rope tension during the holding operation, comprises an adjustable hydrodynamic torque converter 12 which transmits the rotational movements from an electric drive motor 11 to the winch drum 21. When the take-off torque set in the converter is exceeded, rope is unwound and below this torque, rope is wound on. Blades on the converter 12 are adjustable to vary the torque output and lines 23, 24 connect the converter to a cooler 22 ventilated by a fan 25. The torque output from the converter passes to the winch drum 21 via reversing gear 13 and change-over gearing 15, 16, 17. The latter reduces the required take-off torque of the converter during the holding operation and may be positioned between the drive motor 11 and the converter. A change-pole drive motor may however be used, in which case the change-over gearing is not required. The electric drive motor 11 may be positioned remote from the remainder of the apparatus and be coupled thereto by an hydraulic motor arrangement.

Title: Improvements in or relating to card perforating and other machines for recording upon cards
IPC: G06K1/06
Filed: 1929-01-21
Abstract: 328,255. Accounting & Tabulating Corporation of Great Britain, Ltd., and Thomas, A. Jan. 21, 1929. Selective punching-machines.-In a machine in which a carriage with a column of setting members travels step by step over a plurality of columns of set-bars, and the card is punched on depression of a key by raising the die-plate after all punch set-bars have been latched, the depression of the key for operating the punches, through a one-revolution clutch, effects the return of the carriage. The carriage 1 is urged to the right, Fig. 1, during the selecting operation bv a spring drum 1<a> and escapement mechanism 33, and is restored to starting position by the swing- ing of an arm 5 carrying a jockey pulley 3, by a roller 9 on a gear 6. Depression of a key 10, for effecting the punching operation, operates a Bowden wire 11 to swing a lever 12 moving a rod 17 axially. This rod 17 throws in a onerevolution clutch to connect a motor 19 to the gear 6. The cord 2a connected to the carriage and the jockey pulley is anchored to a wheel 4 urged by spring pressure against a stop. If the carriage is to be returned to an intermediate position the spring is stressed when the carriage is arrested by clips 49.' To prevent damage in case the wheel 4 turns one revolution for small travels, a modified wheel 4, Fig. 4 (not shown), is used. The set-bars are latched bv latch-bars controlled by pawls 27 spanned by a release-bar 28. Actuation of a hand lever 30 releases all the latch-bars simultaneously. To release individual latches, a member 31 pivoted on the escapementwheel shaft 32 carries a sliding plate 34 connected by a link 35 to a rocking lever 37 operating a single latch-bar. The bar 28 may be operated by power on return of the carriage by the gear 6 actuating a lever 47 on the rod 43 carrying an arm 42 engaging the lever 30. To operate the bar 28 by hand the rod 43 is moved axially to disengage the lever 47 by an inclined push lever 45. For back-spacing, a pawl 39 on the plate 34 engages the carriage rack 40 when the member 31 is rocked. Operation of a handlever 41 rocks the member 31 and pressure through the hand-lever moves the carriage back and resets a column of selector-bars. Individual pawls 27 are made inoperative by raising the bar 28 by the lever 30 and swinging the latches out of position. Specifications 328,282, [Class 100 (iv), Typewriters &c.], and 328,285 are referred to.
