Materials, special.-A closure for a container has an enclosed space filled with a mixture of rubber and one or more substances not capable of forming a solution or gel with rubber solvents but capable with other liquids. The sealing material may thus contain equal quantities of rubber, as latex, and a substance forming a sol or gel with water, such as gum or glue, a substance forming a sol or gel with common alcohols or ketones , such as manila gum or both. Fillers such as whiting, bentonite, and karaya gum or other colloid with an acid or alkali, softeners such as glycerine, sugars, and diethylene glycol, and preservatives such as sodium fluoride may also be added. The ingredients are mixed with a fluid such as water which can be dried out after applying to the joint surfaces and before fixing by evacuating the container. The Specification as open to inspection under Sect. 91 (3) (a) comprises also closures in which the rubber is wholly or in part replaced by aluminium soap or coconut oil or other soap soluble in water, sulphurized corn or other oil, or beeswax saponified with ammonia, the gum or glue by caesin, starch, or sulphonated castor oil, the fillers by pigments or the water by benzol. This subject-matter does not appear in the Specification as accepted.

Title: Improved process of colouring photographic images
IPC: G03C5/46
Filed: 1938-12-22
Abstract: 522,984. Photographic toning processes; colour photography. CINECOLOR, Inc. Dec. 22, 1938. No. 37269. Convention date, Jan. 3. [Class 98 (ii)] A Prussian blue image is produced from a silver image by converting the silver successively into (1) an insoluble silver salt. (2) silver ferrocyanide, (3) ferrous ferrocyanide and (4) ferric ferrocyanide. The image may be the outer one of two or more colour-record images produced in different strata of a single emulsion layer. Step (1) may consist in converting the silver into silver chloride by means of a solution containing ferric and chlorine ions, e.g., ferric chloride or ferric sulphate acidified with hydrochloric acid. Step (2) is performed with an alkali ferrocyanide solution; step (3) with a solution containing ferrous and halide ions, such as one containing ferrous chloride, bromide, or iodide, and potassium iodide; and step (4) with an oxidizing solution of, e.g., neutral potassium dichromate or hydrogen peroxide. The image is washed between the steps, and may be finally fixed in hypo. In the above-mentioned application to colour photography, the bath used in step (1) is of slowly-penetrating nature, e.g., an acidified ferric chloride solution which may have alcohol as solvent or which may have other retarding addition such as magnesium or aluminium sulphate or sugar; and its action is terminated before it reaches the image in the inner stratum, by a stop-bath as of potassium oxalate. For a two-colour result, the complementary image is produced in the inner stratum before or after the production of the Prussian blue image in the outer stratum. For a three-colour result, the three images may be formed in separate strata of a single thick emulsion layer, the Prussian blue image being outermost; or two of the images may be produced in separate strata, and after toning the outer one Prussian blue, the inner one may be coloured magenta by copper or uranium toning followed by treatment with a basic magenta dye, and the yellow component image may then be printed on the layer by dyeimbibition. It is stated that the process may be applied to sound-track images.

Title: Process for the production of dyeings and printings on cellulose fibres
IPC: D06P3/66
Filed: 1957-12-05
Abstract: Cellulose fibres or textile materials made therefrom are dyed or printed with an aqueous solution or paste of a water-soluble azo, nitro or anthraquinone dye which contains at least one SO2F group, and the dyeing or printing is fixed by steaming. The dyeing or printing may be carried out at an elevated temperature, and dyeing, printing and fixing may be effected in the presence of a weakly alkaline or acid-binding agent.  In an example, 1-aminobenzene-3-sulphofluoride is diazotized and coupled with the sodium salt of 1-(41-sulphophenyl)-5-pyrazolone-3 carboxylic acid, mineral acid being partly neutralized, if necessary, by addition of sodium formate or acetate.  A yellow water-soluble dyestuff is obtained.  Cotton may be dyed or printed with the concentrated aqueous solution and the dyeing, possibly after intermediate drying, may be steamed in the presence of sodium acetate or other acid-binding agent.  During steaming the fibres are acylated with the dye, hydrogen fluoride or fluorides being evolved, and a greenish-yellow dyeing is obtained which is fast to wet-processing, has good light-fastness and may be discharged to a pure white. Printing pastes may be made, using conventional thickeners, binding agents and printing auxiliaries.

Abstract: 1,161,601. Conveyers. MOLINS MACHINE CO. Ltd. 9 Sept., 1966 [13 Sept., 1965], No. 38936/65. Heading B8A. To reduce the risk of damage to the plain ends of cigarettes due to a tendency for the tipped ends of the cigarettes to move ahead of the plain ends when a stream of cigarettes is conveyed, in a direction transverse to the axes of the cigarettes, by a conveyer system comprising opposed conveyer surfaces, means are provided to skew the cigarettes so that their plain ends are in advance of their tipped ends at the commencement of their travel between the opposed conveyer surfaces. As shown, cigarattes C are transferred from a pair of endless chains 51 on to endless band conveyers 54-56 of which band 54 is driven a little faster than band 55, and the latter is driven faster than band 56. As a result the plain ends P of the cigarettes gradually move ahead of their tipped ends T before the cigarettes pass between opposed conveyer surfaces comprising a drum 68 and an endless band 72, Fig. 1. Above the bands 54-56 but spaced therefrom there is a band 83 which is driven at the same speed as the chains 51. The band 83, which engages spaced discs 75, 76 mounted for swing- ing movement on arms 78, 80, is thus able to rise and fall according to the depth of cigarettes at any moment.
