Title: Improvements in and relating to apparatus for separating, by means of a suspension, solid materials having different specific gravities
IPC: B03B5/40
Filed: 1945-09-05
Abstract: 593,455. Wet-separating. DOMANIALE MIJN-MAATSCHAPPIJ N. V., and TROMP, K. F. Sept. 5, 1946, No. 22897. [Class 82 (ii)] In an improvement on the mineral-separating apparatus of Specification 530,742, middlings are removed by a mechanically-driven impeller 26 which periodically sweeps the middlings up and out of an inclined shoot 24 situated at the discharge end with its upper edge just below the surface of the suspension. As long as the impeller is below the surface of the suspension it has a speed such as to displace a quantity equal to that introduced on the inlet side below the level of the top edge of the impeller, and to that end its motion along the shoot 24 is arranged to be accelerated by the cam driving mechanism, as indicated in Fig. 3 (not shown). The impeller 26 carried by arms 27 sweeps middlings along and up the shoot 24 to the discharge 25, and is then lifted and returned to the initial position shown in Fig. 1b by the following mechanism : shaft 31 rotates counterclockwise ; during the greater part of a cycle the lever 30 rotatably mounted thereon is stationary since the roller 33a travels on the cam 35, roller 37a being simultaneously pushed away from the shaft 31 by a cam 40. Thus, the impeller 26 through the interaction of lever 37, strap 38 and lever 27 is moved towards the right over the shoot 24, at a progressively increasing speed. At the end of this sweep the roller 33a reaches an enlarged portion of the cam 35 and the lever 30 is raised together with the impeller, by the action of the lever 33 and the strap 32 attached to the lever 30. Immediately thereafter the rollers 33a, 37a meet downwardly sloping portions of their respective cams whereby the impeller is returned to its initial vertical position, lowered into the suspension liquid, and the cycle is then repeated. Specification 466,964 also is referred to.

Abstract: 1454315 Polyimides WESTINGHOUSE ELECTRIC CORP 23 May 1974 [24 May 1973] 23074/74 Heading C3R A composition for making a soluble, curable polyimide precurser comprises (i) a dianhydride of a tetracarboxylic acid and (ii) a tetracarboxylic acid in molar properties 50 to 70% (i) and 30 to 50% (ii), together with (iii) a stoichiometric amount of an aromatic diisocyanate and (iv) sufficient solvent for (i), (ii) and (iii) to make a solution of solids content 12 to 25 wt. per cent. The precurser is then made by heating the composition at 30 to 70 C. until CO 2  evolution substantially ceases and then at 30 to 100 C. until the viscosity on the Gardner-Holdt scale is 2 to 26 at 18% solids. The same acid is preferably used for (i) and (ii) in which case the composition can be obtained by dissolving (i) in the solvent and then adding water to convert an appropriate proportion to (ii). The proportion (i) : (ii) is indicated to be critical in that too little (i) leads to brittle and too much to insoluble products. Various components (i), (iii) and (iv) are specified, (ii) preferably being aromatic. The diisocyanate is preferably added last and slowly to avoid discolouration and gel formation. In specific examples (i) and (ii) are pyromellitic or 3,31,4,41-benzophenone tetracarboxylic dianhydride and acid; (iii) is p,p<SP>1</SP>- diisocyanatodiphenyl either or methane and (iv) is dimethylacetamide while benzyldimethylamine is used as catalyst. Other catalysts mentioned are stannous octoate and triethylamine. Uses.-The precursor solution can be used as an insulating wire enamel or to form an insulating film or sheet useful for electrical insulation or slot liners. To form a film the precursor solution concentration is adjusted to 10 to 20% and spread on a substrate, e.g. an aluminium sheet which is then passed through an oven to cure the precursor. To form sheets paper or fabric is coated with the precursor solution and then cured.

Title: Improvements in and relating to plasticizers and plasticized coating compositions
IPC: C09D101/18
Filed: 1938-08-06
Abstract: 517,236. Plasticizers and plasticized coating compositions. SYLVANIA INDUSTRIAL CORPORATION. Aug. 6, 1938, No. 23252. Convention date, Aug. 7, 1937. [Classes 2 (ii) and 2 (iii)] Plasticizers for use in coating compositions are made by the interaction of a fatty acid or a fatty acid anhydride with a monocarboxylic keto-aromatic acid or a substitution product thereof having the general formula R-COR<1>-COOH, where R and R<1> represent aromatic nuclei. The composition is prepared by the admixture of the plasticizer prepared as above with a cellulose base preferably nitrocellulose. If desired other plasticizers may be added such as dibutylphthalate triphenylphosphate tricresylphosphate, and benzoyl-o-benzoic acid or its esters. Instead of nitrocellulose other cellulose derivatives such as esters, ethers or ester-ethers may be used, or a lacquer base resin such as polymerized vinyl resins. If it is desired to prepare waterproofing compositions an animal, vegetable or mineral wax may be added such as dammar, ester gum, or paraffin wax, together with a blown oil such as blown rapeseed oil should this be necessary to render the wax compatible with the lacquer base. Lacquers are made by dissolving the composition prepared as above in a suitable solvent such as a mixture of ethyl acetate, butyl acetate and toluene. The fatty acid component of the plasticizer may include any straight chain fatty acid such as acetic, propionic, butyric, valeric, and stearic acids or their anhydrides, and the aromatic component includes a mono-carboxylic acid of the benzophenone series or its substitution products such as p-chloro-benzoyl-obenzoic acid. The plasticizer is preferably prepared in the presence of a small amount of condensing agent such as sulphuric acid. It is preferred that the total amount of plasticizer in the composition should not be less than 25 per cent., and for a non-tacky sealing composition should be from 35-40 per cent. The compositions may be used for coating wood, leather, paper or fabrics. In an example of the preparation of the plasticizer o-benzoyl benzoic acid, and acetic anhydride are reacted in xylene solution in the presence of a small amount of concentrated sulphuric acid by boiling under reflux for three hours. The plasticizer crystallizes from the reaction solution and may be purified by recrystallization.
