Abstract: 1,159,327. Heating and cooling centrifugal moulds. GOODYEAR TIRE & RUBBER CO. 5 March, 1968 [3 April, 1967], No. 10616/68. Heading B5A. A mould 1 is heated and cooled by passing hot or cold oil through the cavity 3 formed between the mould 1 and the outer shell 2, the oil is fed to the mould through inlet 4 at a pressure above atmospheric and is removed from the mould at outlet 5 at a pressure less than atmospheric so that the pressure on the oil within the mould is less than atmospheric. The oil is fed to the mould at a pressure of 1-30 p.s.i.g. Suitable oils are those of the diphenyl or diphenyl ether type or mixtures thereof. The oil may be blanketed with a gas such as nitrogen or carbon dioxide. Suitable thermoplastic moulding materials mentioned are liquid and dry plasticised polyvinyl chloride and related vinyl polymers, polystyrene and terpolymers of acrylonitrile, butadiene and styrene. The thermoplastic material is fed to the mould, e.g. an electroformed mould which is heated by passing through hot oil, the mould is rotated to coat its surface, heated to fuse the thermoplastic material and cooled by passing cold oil through the cavity.

Abstract: 807,280. Tanks. UNTHANK, D. G., and SILLEY, A. J. May 24, 1957 [April 11, 1956], No. 11072/56. Class 69 (1). A tank consists of a rigid top 10 and a rigid base structure 11 connected by a flexible bag 12 and capable of being folded into a plurality of superimposed pleats. Three horizontal frames 13 are provided to define the outer fold lines of the pleats and the hinge pins of linking plates 14 define the inner fold lines of the pleats. Liquid is introduced with pressure at the lower end of the tank and the upper sections of the tank are constrained to rise in an unexpanded condition whilst the lower sections are expanded by the entering liquid. The upper sections are released automatically in succession for expansion as a section below attains a predetermined degree of expansion. The frames 13 are provided with brackets 15 carrying pivoted hooks 16. The brackets on each of the frames 13 below the top also carry lugs 17 in position each for engagement by a respective hook 16. Slidable plungers 18 loaded by springs 19 are provided in the brackets 15 below each lug 17. Cam blocks 20 are provided on one of each pair of plates 14. As the plates 14 move into the position corresponding to the expanded condition the cam blocks 20 take up the position shown in broken lines in Fig. 2 and move the plungers 18 against their spring loading to effect disengagement of the hooks 16 from the lugs 17. Specification 668,188 is referred to.

Title: Photographic colour transfer materials and process
IPC: G03C8/44
Filed: 1968-03-07
Abstract: 1,220,474. Photographic dye-diffusion colour materials. INTERNATIONAL POLAROID CORP. March 7, 1968 [March 10, 1967 (2); March 16, 1967], No.11193/68. Headings G2A and G2C. A photographic dye-diffusion material comprises coated on a support in sequence, a photo-sensitive silver halide emulsion layer having associated therewith either in the emulsion or in a layer between the emulsion layer and the support, a compound which upon exposure and development of the layer with an alkaline processing composition having a first pH provides an imagewise distribution of a dye-image-forming material which is soluble and diffusible in alkali at the first pH, a dyeable polymeric layer permeable to alkaline solution, a transparent polymeric acid layer permeable to alkaline solution and having sufficient acid groups to reduce the pH of a processing solution having the first pH to a second pH at which the dye-image forming material is insoluble and non-diffusing, and a transparent layer, the adhesion between the dyeable layer and the silver halide layer next to it being less than between the other layers, the material forming part of a film unit as shown in Fig. 2 which contains the processing solution of the first pH in a rupturable container 11 which is bound to a leading edge of the dye-diffusion material by tape 33 so that on passage through rollers 35, the processing liquid is squeezed between the dyeable layer and the adjacent silver halide layer. The other edges of the material are bound by binding tape 28, see also Fig.1, so that the material remains an integral unit before and after processing. The dyeable layer may be transparent, the support layer may be opaque and the processing liquid contains an opacifying agent, e.g. TiO 2  so that after exposure through the dyeable layer and processing by rupture of the container 11, diffusion of the dye-image forming material occurs from non-exposed areas of the emulsion giving a positive colour image in the dyeable layer, which image is viewed against the spread layer of opacified processing liquid. Further diffusion of dyeforming material is prevented by the lowering of the pH caused by the polymeric acid layer. The preferred dye-image-forming materials are dyedevelopers but techniques using colour couplers and colour developer or the diffusion of complete dyes may be used. The dye-diffusion material may contain a plurality of differently sensitized emulsion layers each associated with its own dye-imageforming material to form a multi-colour material.

Abstract: 1,263,505. Purifying hydrofluoric acid; silicon tetrafluoride. BUSS A.G. 4 March, 1969 [9 March, 1968], No. 11423/69. Heading C1A. High per cent hydrofluoric acid, substantially free from SiF 4 , is obtained from H 2 SiF 6  solutions or HF, SiF 4  and/or H 2 SiF 6  mixtures by contacting the solution or mixture in an absorption column with an organic solvent for HF and, to a lesser extent, H 2 O and SiF 4 , thereafter scavenging the said solvent and its contacts in a separating column by contra-flow of a gas inert to H 2 O, HF or H 2 SiF 6 , to remove at least the majority of the SiF 4  and H 2 O therefrom and then separating HF from the scavenged solvent, the process being carried out above the condensation temperature of any vapour mixture present. Suitable inert gases are nitrogen or carbon dioxide, and the inert gas is preferably also led into the absorption column to improve the selectivity of the solvent for HF as compared to H 2 O and SiF 4 . Suitable solvents are aliphatic polyethers or polyols especially polyglycols. The inert gas may be preheated and the temperature suitably drops from 135‹ to 100‹ C. in contraflow to the liquid phase.

Abstract: 831,858. Steel manufacture. UNITED STATES STEEL CORPORATION. April 11. 1958, No. 11669/58. Class 72 [Also in XII] A method of making steel in an open hearth furnace comprises, when the carbon content of the metal is in excess of 0.3%, adding between 200 and 1,000 cu. ft. of oxygen per ton of metal in a plurality of streams striking the bath sufficiently far apart to provide isolated reaction zones, each stream delivering more than 6,500 cu. ft. per hour at a velocity of between 400 and 1,100 feet per second. As shown, oxygen may be supplied at the centre of an open hearth furnace 2 through a lance 4 which has a number of orifices and which is spaced 6-18 inches above the bath surface. The angle the orifices make with one another and with the centre-line of the lance are so adjusted that the stream of gas from each orifice produces a separate reaction zone. The lance may be used from melting down to the end of the process when low carbon steel (carbon below 0.10%) is being produced, or, when the steel is intended to have more than 0.2% carbon, the oxygen addition is stopped when the carbon reaches 10-15 points above the tap value. It is stated that the process reduces the time required and the amount of fuel used.
