Title: Improvements in the manufacture of coloured articles
IPC: D06P1/92
Filed: 1944-04-18
Abstract: Sheets, rods, tubes and other articles of synthetic resins of the kind which are substantially infusible and substantially insoluble in orgainic liquids are coloured by treating them with solutions of dyes in liquids consisting substantially of polyhydric alcohols or esters or ethers thereof having a boiling point of at least 120 DEG  C. or in liquids consisting substantially of such compounds and water in an amount which does not exceed 50 per cent of the weight of the liquid. The resins may be of the p  phenolaldehyde, phenol-ketone, urea-formaldehyde, thiourea-formaldehyde or melamine-formaldehyde types, resins obtained by the polymerization of suitable unsaturated organic compounds such as unsaturated esters, e.g. esters of unsaturated alcohols with polycarboxylic acids, or esters of unsaturated acids, e.g. suitable esters of acrylic acid or its homologues. Specified solvents for the dyestuffs are thiodiglycol, glycol, glycerol, diethylene glycol and triethylene glycol and the esters and ethers thereof, such as mono-, di- and tri-acetins, glycol - monomethyl - ether, diethylene glycol - monoethyl - ether, glycol - monomethyl - ether - acetate and diethylene glycol monomethyl-ether-acetate.  Water-insoluble dyes, e.g. of the aminoanthraquinone, azo, nitrodiarylamine and nitroaminodiarylmethane types, are preferred, the following being specified: 4.41-diamino-3.31-dinitro-diphenylmethane, 4-nitroamino - 21.51 - di - (methyl or methoxy) - azo - benzene, 4-nitro-21-methyl-41-di-(b -hydroxyethyl) aminoazobenzene, 1.4 - di - (b  - hydroxy - ethylamino)-5-hydroxyanthraquinone, 1.4.5.8-tetraminoanthraquinone and 1-amino-4-methyl-aminoanthraquinone.  Water-soluble dyes may also be used, e.g. acid dyes such as those containing a sulphonic, carbonylic or acid sulphuric ester group, and basic dyes.  The dyeing may be carried out under pressure at temperatures above the boiling point of the solvent.  In examples: (1) sheets consisting of polymerized diallyl phthalate are treated with a solution of 4-nitro-41-amino-21.51-dimethoxyazobenzene and 1-amino-4-methylaminoanthraquinone in glycerol (2 parts) and water (1 part) in an autoclave at 150 DEG  C. for 4 hours; if glycerol is used alone, the same results are obtained by heating at 170 DEG  C. without pressure; (2) sheet material of phenol formaldehyde resin is dyed in a solution at 80 DEG  C. of 4-nitro-41-amino-21.51-dimethoxyazobenzene or of specified mixtures of the dyes referred to above in a mixture of diethylene glycol (2 parts) and water (1 part).

Title: Improvements in or relating to the production of bituminous formed articles
Inventor: SOMMER ALBERT
IPC: C08L95/00
Filed: 1960-03-01
Abstract: Moulded bodies such as blocks, tubes briquettes or paving slabs are prepared by mixing granular mineral particles e.g. of stone, ore or coal with bitumen as a binder by coating the particles with a bitumen film of about 10m  thickness or less and moulding the mixture by compression so as to leave voids between the particles equal to 5-30% by volume of the mass and hardening the bitumen in the moulded body by the action of air at 300-600 DEG F.  In an example, granular Swedish magnetic iron ore is coated with liquid bitumen and conveyed to a briquette press when it is compacted between rollers at 300-500 DEG F. and 8,500 lbs./sq.in., leaving voids of about 15% of the total volume. The briquettes are then conveyed through an oven at about 500 DEG F. for 30 minutes. In a second example, natural asphalt rock with an initial bitumen content of 3-4% was used and coated with liquid bitumen to bring the bitumen content up to not more than 10%. Specification 599,384 and U.S.A. Specifications 2,572,068 and 2,726,852 are referred to.ALSO:Mineral particles, e.g. of stone, coal or ore, are coated with a thin film of liquid bitumen.  The particles are fluffed up by rotation of an impeller unit with oppositely rotating shafts and are maintained in suspension in a floating zone above the blades. Liquid bitumen is atomized into the loose floating mass, and the coated particles removed, e.g. by conveyer. Specification 599,384 and U.S.A.  Specifications 2,572,068 and 2,726,852 are referred to.

Title: Motion-picture film cassettes
IPC: G03B17/26
Filed: 1973-02-14
Abstract: 1377033 Cassette; film processing POLAROID CORP 14 Feb 1973 [17 Feb 1972] 7305/73 Headings G2E and G2X A cine film cassette includes a device for processing the exposed film within the cassette, this device being actuated by movement of the film within the cassette. In Fig.1 the film passes from the supply reel 8 to take-up reel 10 during exposure and projection and in the reverse direction during processing. The processor includes a housing 33 pivoted at 34 and having a wick 40 and coating roll 36. The processing solution is initially stored in a pod 42 rupturable by knife edge 44. In operation, during rewind after exposure an aperture or section A of the film is engaged by hook 69. The hook 69 is moved upwards and moves the cable 47 which in turn pivots the housing 33 clockwise and causes the edge 44 to rupture the pod 42. The arm 52 is held in its raised position by detent mechanism 64 and the processor held down in its lower position by hook 56 and bar 59. Hook 69 is subsequently detached from the arm 52 by the film driving force and carried by the film until attracted by magnet 76. In its lowered position the roll 36 is driven by the engagement of gears 74, 75. Nearing the end of the film rewind another aperture (not shown) in the film engages the hook 57 and removes it from its mount 56. This causes the housing 33 to pivot anti-clockwise under the action of spring 54 and take the processor out of action. In a modification Fig.20 to 22 (not shown) the cable moved by the hook 69 is used to rupture the pod as already described but the housing of the processor is moved by a lever. This lever is moved by a tension roller mounted in the position of roller 13 in Fig. 1. The tension roller is mounted on a pivoting arm and when film rewind commences the roller and its arm move due to film tension towards the processor and the arm pivots the lever to move the processor. In the embodiment of Fig.11 the processor 79 is fixed and the solution 90 contained by sheet 89. Sheet 89 is initially attached to the base of the processor 79 but can be lifted by engagement of the hook 78 with a film aperture. Movement of the hook 78 moves cable 103 which in turn moves block 107 to lift pressure plate 109 towards the outlet nozzle of the processor 79. The hook 78 is detached as in Fig.1. Towards the end of rewind another film aperture is engaged by hook 118 and carries along. This permits the pressure plate 109 to return to its original position. The hook118 may also be used to close the nozzle.

Title: Improved treatment of carbon black
IPC: C09C1/56
Filed: 1949-03-22
Abstract: Carbon black is improved for synthetic rubber compounding by first treating the carbon black to increase its volatile content and subsequently decreasing the volatile content of the treated black until the volatile content is substantially the same as the initial value.  The volatile content may be increased, e.g. (1) by heating at 750-800 DEG F. under atmospheric conditions, (2) by treating with nitric acid or (3) by treating with ozone.  Thus, carbon black (volatile content 4-7 per cent) is heated in air at 750 DEG F. for 1 hour until the volatile content is increased by at least 2 per cent and the treated black is then heated at 1200 DEG F. for 1/2 hour in absence of air or in a neutral or reducing atmosphere.  The carbon black should be kept dry between the two steps or dried prior to the second.  Specification 596,785 is referred to.
