Title: Water-soluble dyestuffs containing thiocyano-triazinylamino groups
Inventor: PRICE RAYMOND
IPC: C09B62/04
Filed: 1958-02-12
Abstract: The invention comprises water-soluble dyes containing amino groups which are substituted by s-triazine groups containing at least one thiocyanato group attached to a carbon atom thereof. The dyes are prepared by reacting a dye containing a reactive amino group with a s-triazine having a halogen atom on one carbon atom of the nucleus and a thiocyanato group on at least one of the other carbon atoms of the nucleus.  The amino group containing dyes may be of the stilbene, azine, dioxazine, o-nitrodiarylamine, anthraquinone, phthalocyanine and, preferably, azo series, including metal-free and metallized mono- and poly-azo dyes.  Many suitable amino-substituted dyes and intermediates for their preparation are specified.  The dyes are reactive with materials containing amino groups, such as leather and animal and superpolyamide fibres and more particularly with materials containing hydroxyl groups, such as cotton, linen and viscose rayon which are dyed in alkaline medium.  In an example potassium thiocyanate is reacted in acetone with cyanuric chloride to give a solution of 2- chloro4 : 6- dithiocyano -striazine which is reacted with 2-(41-amino -21- methylphenylazo) naphthalene -4 : 8- disulphonic acid in the presence of sodium bicarbonate.  Many similar examples wherein metallized and metal-free mono- and poly-azo, anthraquinone and phthalocyanine dyes are prepared are specified. Specification 838,337 is referred to.

Alternatively, the corrugations may be helically inclined, or both these expedients may be used together. The inner ridges of the corrugations are cut off obliquely at the discharge end of the flame tube to form openings 12, and a collar is provided to deflect inwardly the air flowing through the space 6.

Abstract: 1441476 Photo-sensitive lithographic printing plate production FUJI PHOTO FILM CO Ltd 31 Jan 1974 [31 Jan 1973] 04666/74 Heading G2C A photo-sensitive lithographic printing plate precursor is produced by forming an anodic oxide film on an aluminium plate in or on which film phosphoric acid radical is present, the phosphoric acid being reacted with the aluminium oxide or physically adsorbed thereto, applying to the film a solution of a hydrophilic polymer in an organic solvent containing 0-50% by volume of water, drying the solution to leave a hydrophilic polymer layer on the film and applying a layer of a photosensitive resin (see Examples 1, 2 and 5) or photopolymerizable monomer (see Examples 3 and 4), on the film of the hydrophilic polymer. The organic solvent may be an alcohol, amide, ketone, glycolmonoether or dimethylsulphoxide. The hydrophilic polymer may be a cellulose derivative, polyvinyl alcohol or a derivative thereof, polyvinyl pyrrolidone, polyvinyl methyl ether, polyvinyl methyl ether/maleic anhydride copolymer, styrene/maleic anhydride copolymer, vinyl acetate/maleic anhydride copolymer or a mixture thereof. The photo-sensitive resin may be dimerized on exposure and may be polyvinyl cinnamate, a temary condensation polymer of 4,4'- isopropylidene-bisphenol, divanillal-cyclopentanone and neopentyl-bischloroformate (Example 1) or polyethylmethacrylate-cinnamate (Example 5).

Title: Improvements in or relating to imitation fires
IPC: F24C7/00
Filed: 1929-02-12
Abstract: 329,319. Automatic Telephone Manufacturing Co., Ltd., and Saxby, R. N. Feb. 12, 1929. Imitation fires.- Moulded glass or like transparent " fuel " located above a source of light 1 in an imitation fire is formed in blocks having the underside 2 shaped so that the light enters it normally over substantially the whole area. Portions 3, 4 of the upper surface are so inclined as to produce total internal reflection, the light so reflected emerging sideways from the block. Through other parts of the surface, such as that provided by the tongue 5, the light passes directly. The undersides and the totally reflecting surfaces of the blocks are preferably smooth, and the surfaces through which the light emerges preferably frosted and coloured. The totally reflecting surfaces may be covered by opaque or semi-opaque mouldings representing coal or unburnt fuel. The blocks may be supported in an iron frame, and be so shaped as to take up definite positions in relation to it and to each other. In cases where a rotary flicker device is employed over the centrally situated source of light the blocks may be modified by being formed on the underside with a series of waves, the axes of which lie transversely to the paths traced on the undersurface by the moving incident beams from the flicker device. The waves on the side of the fire where the incident beams move from front to back, and would therefore tend to produce on the rear reflector a false effect as of descending flames, are formed as a series of convexities separated by angular troughs, of the form shown on the right-hand side of Fig. 2. The refraction occurring at the convex surfaces reverses the angular movement of the beam traversing them and so produces the desired effect of rising flames on the reflector. On the other side of the fire, where the beams move from rear to front, the waves are formed as at the left-hand side of Fig. 2, the dispersive effect of the concavities tending to increase the angular movement of the beams and hence the normal rising flame effect on this side of the fire. The curvature of the waves is not sufficient to interfere with the internal reflection effects at the upper surfaces. Fig. 2 represents slabs which may be placed at the rear of the fire to assist the " rising flame " effect, and in which the waves on the undersurface run from front to rear of the fire, in view of the fact that the moving beams from the rotating flicker device pass sideways across them.
