Title: Pigment Dispersions
Inventor: BACKHOUSE MARGARET PEDDIE
IPC: C09D7/45
Filed: 1965-08-04
Abstract: 1,159,252. Pigment dispersions containing an addition polymer as dispersant. IMPERIAL CHEMICAL INDUSTRIES Ltd. 21 July, 1966 [4 Aug., 1965], No. 33353/65. Addition to 1,108,261. Heading C3P. A dispersion comprises an organic liquid, a pigment dispersed in the organic liquid and a dispersant for the pigment, the dispersant comprising an addition polymer chain solvated by the organic liquid and having attached thereto at least one group of the formula where R is an aliphatic radical which may contain one or more additional hydroxyl groups. The said group is produced by reacting a hydroxyl-substituted carboxylic acid with an epoxy group contained in the addition polymer chain or by reacting an ester of such an acid, containing an epoxy group in the alcohol moiety, with a carboxyl group in the polymer chain. In Examples 1 and 2, lauryl methacrylate, n-butyl methacrylate and glycidyl methacrylate are copolymerized in an organic medium, the resulting copolymer is esterified with glycollic or lactic acid and a mono-azo yellow or vegetable black pigment is dispersed in the solution of esterified copolymer. Copolymers of methyl methacrylate and glycidyl methacrylate are produced in Examples 3 to 5 and esterified with gluconic acid, 12-hydroxystearic acid or glycollic acid before addition of a black pigment to the copolymer solution. A copolymer dispersant is produced in Example 6 by esterifying polyhydroxystearic acid with glycidyl methacrylate, copolymerizing the resulting ester with methyl methacrylate and glycidyl methacrylate, and esterifying the copolymer with lactic acid, the dispersant being used in the production of a black pigment dispersion. In Example 7, a methyl methacrylate-glycidyl methacrylate copolymer is reacted with shellac and used in the preparation of dispersions containing phthalocyanine blue pigment and/or TiO 2 . The pigment dispersions may be incorporated in paints containing acrylic or alkyd resins or polyvinyl chloride.

Title: Improvements in and relating to non-positive displacement compressors
IPC: F04D27/02
Filed: 1965-08-05
Abstract: 1,117,479. Axial-flow compressors. BROWN BOVERI & CO. Ltd. Aug. 5, 1965 [Aug. 7, 1964], No.33555/65. Heading F1C. [Also in Division G3] In a non-positive displacement compressor, e.g. an axial-flow compressor, having adjustable stator blades 3, or adjustable rotor blades, a probe 11 for detecting error in the flow angle of the working fluid when the pumping limit is reached is adjustable relative to the stator to compensate for variations in flow angle relative to the probe due to blade adjustment. Detected error results in opening of a diaphragm actuated valve 30 to relieve the pressure of oil supplied at 31 and thereby to open a piston actuated blow-off valve 32, 33. The blades 3 may be adjusted in accordance with a pressure difference in the compressor or with delivery pressure by a bellows 24 which through a valve 25 relieves the pressure of oil supplied at 26 and acting on a piston 27 which controls devices 28 for rotating the blades and probe. Coupling between probe and blades may be mechanical, hydraulic, pneumatic or electrical. The blades and probe may be adjusted through gearing having the same or a different ratio, Fig. 1 (not shown), or the probe may be adjusted through a cam-actuated means, Fig. 2 (not shown). Since the flow angle varies along the length of each blade, the variation of flow angle relative to the probe due to blade adjustment may be compensated by radial movement of the probe. The probe may be a yawmeter, Fig. 4 (not shown), with two or more inlets. Alternatively it may be formed by a body having two opposed pressure fluid outlets controlled by a common leaf-spring subjected to the main flow, Fig. 5 (not shown), or formed by a leaf-spring subjected to the main flow and fitted with strain gauges.

Abstract: 1294805 Thermal regenerators GENERAL MOTORS CORP 22 July 1971 [8 Sept 1970] 34453/71 Heading F4K  In a gas turbine engine rotary regenerator 14 comprising an annular matrix 16 serving to exchange heat between hot low pressure exhaust gases from the turbines T 1 , T 2  and cold high pressure air from a compressor 10, the matrix includes a catalytic material for treating the hot exhaust gases passing therethrough to eliminate noxious constituents such as carbon monoxide, unburned hydrocarbons and oxides of nitrogen. As a result of the treatment reactions heat is released, this heat being absorbed by the matrix and used to further increase the temperature of the cold high pressure air. As shown the matrix comprises a honeycomb like structure formed of alternate layers of flat ceramic sheets (56, Fig. 2) and corrugated ceramic sheets (58) which are permanently chemically bonded by firing at an elevated temperature. The catalyst may be impregnated in the ceramic either during forming of the honeycomb or afterwards. Alternately the catalyst can be a surface coating 60 on the matrix walls 18 defining parallel gas passages 20 extending between the matrix end faces 30a, 30b. Examples of suitable catalysts are platinum, palladium, Cu, Ni, Co, Fe, Cr and Mn oxides and mixtures thereof.  When a metallic matrix is used it is necessary to first provide a thin layer of for example alumina on the metal surface with the catalyst being present as either an impregnation in the alumina or as a coating thereon. The heated high pressure air on leaving the matrix passes to a combustor 22 where fuel is burned. The hot gas from the combustor then enters the turbines T 1 , T 2  arranged in series.

Title: Flame-resistant modified cellulosic textiles
IPC: D06M13/487
Filed: 1958-10-28
Abstract: Flame-resistant textiles comprise chemically modified cellulose having the general formula: <FORM:0901463/IV(a)/1> in which X represents an unmodified or modified cellulose molecule residue, n represents 0 to 3, Z represents P-O-R or S=O, R represents hydrogen, an unsubstituted or substituted alkyl or aryl group or a salt-forming cation, Y represents a 1-aziridinyl, a dialkylamino, an alkyl, an alkenyl or an aryl group and Q represents oxygen or sulphur; or structural units derived therefrom in which the free 1-aziridinyl groups in the modified cellulose have been reacted with other inorganic acid groups or with further 1-aziridinyl compound.  The textiles may be produced by treating a textile material comprising cellulose previously modified to correspond to the formula: <FORM:0901463/IV(a)/2> in which X, n, and Z have the significance stated above, and M represents hydrogen or a salt-forming cation, with a solution of at least one 1-aziridinyl compound containing two or more 1-aziridinyl groups attached directly to a phosphorus atom. The preferred 1-aziridinyl phosphorus compounds correspond to the general formula:  <FORM:0901463/IV(a)/3> in which Q represents oxygen or sulphur and Y represents a 1-aziridinyl, a dialkylamino, an alkyl, an alkenyl or an aryl group.  The previously modified cellulose may be phosphonomethyl cellulose, sulphoethyl cellulose, cellulose phosphate or cellulose sulphate.  When M or R represent a salt-forming cation, this is preferably replaced to liberate the free acid, e.g. by treating the salt with a dilute aqueous solution of a mineral acid.  In an example, phosphonomethylated cotton sheeting containing 0,44% phosphorus is converted into the free acid form by soaking it in a 3% aqueous hydrochloric acid, washed with water, air dried, padded through a 10% aqueous solution of tris(1-aziridinyl) phosphine oxide and cured for five minutes at 130 DEG C.  The cellulosic materials of the invention are insoluble in water and possess a flame resistance which is durable to bleaching and laundering.  Specification 893,283 is referred to.
