Title: A new process for the production of stable aqueous emulsions of polyvinylacetals
Inventor: HECKMAIER JOSEPH
IPC: C08J3/05
Filed: 1958-11-25
Abstract: A stable aqueous emulsion of a polyvinylacetal is produced by converting a moist polyvinylacetal, in which the aldehyde component is a straight or branched chain aliphatic aldehyde containing at least eight carbon atoms, or a moist polyvinylacetal, obtained by copolymerizing a vinyl ester with an unsaturated aliphatic carboxylic acid containing one or two carboxyl groups followed by at least partial hydrolysis of the ester groups and reaction of the free hydroxyl groups formed with an aldehyde, to a plastic state by heating and milling at a temperature of 100 DEG -140 DEG C., cooling the mass and adding water slowly with agitation to the mixture obtained.  The acid may be acrylic, crotonic, fumaric, maleic or itaconic acid.  The emulsifying agents may be the alkali-metal and the ammonium salts of long-chain saturated and unsaturated fatty acids such as oleic acid, stearic acid, linolic acid, palmitic acid, lauric acid; and alkyl aryl sulphonates and polyglycol ether sulphonates, which may be employed with or without the addition of protective colloids such as polyvinyl alcohol, gelatin, sodium caseinate, albumen, dextrin, sodium cholate, gum tragacanth, saponin, gum arabic, and water-soluble cellulose derivatives.  Specified emulsifying agents are sodium oleate, sodium linolate, sodium palmitate, sodium stearate, sodium laurate, and polyethylene glycol ether sulphonate.  The preferred aldehydes are butyraldehyde and caprylic aldehyde.  The resulting emulsions may be converted into films and used as an intermediate layer in the manufacture of laminated safety glass.

Title: Improvements in and relating to the production of anthraquinone derivatives
IPC: C07C225/34
Filed: 1928-12-28
Abstract: 331,537. Loveluck, R. J., Beckett, E. G., Thomas, J., and Scottish Dyes, Ltd. Dec. 28, 1928. Anthraquinone derivatives.-The products obtained by oxidizing an o-amino-#-sulphonic acid of anthraquinone with potassium persulphate in sulphuric acid are treated with a halogenating agent, for example sodium chlorate and hydrochloric acid, whereby the sulphonic acid group is replaced by halogen. Reduction of these halogenated derivatives by means of sodium hydrosulphide, or hydrogen sulphide and ammonia or neutral hydrosulphite yields the corresponding o-aminohalogen derivatives. By the persulphate oxidation 1-amino-2-sulpho-, and 2- amino-3-sulphoanthraquinone are converted to 1- nitroso-2-sulpho- and 2-nitro-3-sulpho-anthraquinone respectively, and the latter by the treatment with sodium chlorate and hydrochloric acid are converted to 1-nitroso-2-chlor- and 2-nitro-3- chloranthraquinone respectively. In example (1) 1-amino-2-sulphoanthraquinone is converted by the above processes to 1-nitroso-2-chloranthraquinone and the latter reduced with sodium hydrosulphide to 1-amino-2-chloranthraquinone; the product is purified by dissolving in strong sulphuric acid, diluting the solution when the sulphate precipitates out, filtering and decomposing the sulphate with water; (2) 2-amino-3- sulphoanthraquinone is converted by the above means to 2-nitro-3-chloranthraquinone and reduced with sodium hydrosulphide to 2-amino-3- chloranthraquinone. These products may also be purified as described in Specification 268,537.

Title: Improvements in and relating to means for feeding molten glass to a rolling apparatus for producing a continuous glass strip
IPC: C03B13/04
Filed: 1929-12-28
Abstract: 347,585. Glass manufacture. PILKINGTON BROS., Ltd., 631, Tower Building, Water Street, Liverpool, LE MARE, E. B., Holly Mount, Laurel Road, St. Helens, and WALDRON, F. B., Norwood, Eccleston Park, Prescot, both in Lancashire. Dec. 28, 1929, No. 39673. [Class 56.] Rolling.-Relates to mechanism for adjusting the position of a gate which regulates the flow of molten glass through a spout from a tank furnace to a rolling-apparatus for continuously producing glass in strip form. According to the invention, a gate is supported at each end by devices which can be operated simultaneously to raise or lower it, and also to tilt it in its own plane or allow it to move angularly. The gate is suspended at each end from a rod 3 which screws into a long tube 8, and this tube slides through a worm wheel 18 but is prevented from rotating by a feather 10. The wormwheel rotates within a spherical block 12 which rests in a spherical seating 13 of a casing 14 secured to a beam above the feed spout. The tube 8 is pressed downwards by a spring 16, but a nut 15, which screws on to the upper end of the tube, allows it to be moved through the worm wheel 18. Both worm wheels are engaged by worms on a shaft 6, so that rotation of this shaft raises or lowers both ends of the gate simultaneously. Rotation of the nut 15 raises or lowers the tube 8 and thus allows one end of the gate to be moved relatively to the other to tilt the gate in its own plane. The spherical blocks 12 allow the gate to move angularly so that it can accommodate itself to its seating. According to the Provisional Specification, two gates may be used in the conduit, and one of them may be closable rapidly in case of emergency.

Title: Improvements relating to gas turbine power plants
IPC: F02C3/073
Filed: 1959-11-24
Abstract: 884,646. Gas turbine plants; axial-flow compressors. DAIMLER-BENZ A.G. Nov. 24, 1959 [Nov. 26, 1958], No. 39837/59. Classes 110 (1) and 110 (3). In a gas turbine power plant of the type in which a number of coaxial rotors each comprise radially inner compressor blading, radially outer turbine blading, and radially therebetween a rotor ring separating the compressor flow from the turbine flow, which flows are in opposite directions, one of the rotors being secured to a power output shaft which may carry an airscrew, the other rotors being individually rotatable, consecutive rotors being contra-rotational, the compressor is constructed as a supersonic compressor. In Fig. 1, air enters the inner passage and is compressed in the compressor which comprises rotor blades 12<SP>2</SP> and 12, the air then entering combustion chamber 16 where fuel is burned, the combustion gases then flowing through the turbines which comprise rotor blades 11, 11<SP>1</SP>. The blades 11 constitute the compressor-driving turbine and they are mounted radially outwardly of the compressor blades 12, the blades 12 being secured to rotor discs L 1  which are independently rotatably mounted on a stationary shaft 14. The blades 12 and the blades 11 associated therewith are separated by a ring member 13. The blades 11<SP>1</SP> constitute a separate power turbine and they are mounted radially outwardly of compressor blades 12<SP>1</SP>, the blades 12<SP>1</SP> being mounted on a rotor disc L 1 <SP>1</SP> secured to a shaft 15 which may drive an airscrew through reduction gearing. The blades 12<SP>1</SP> may act as a rotating inlet guide vane assembly. The blades 11<SP>1</SP> of the separate power turbine are low-pressure blades. In a second embodiment similar to Fig. 1, and shown in Fig. 4, the power turbine L 4 1 is disposed adjacent the combustion chamber so that it is a high-pressure turbine, the compressor blades associated therewith constituting a rotating outlet guide vane assembly. The air inlet is indicated at E 4  and the combustion gas outlet at A 4 . The airscrew driven by the power turbine is in this case of the pusher type. In a further embodiment the engine is similar to that shown in Fig. 4 but the engine is mounted with combustion chamber forward so that the airserew is of the tractor type. The air intake to the compressor is through lateral openings and the gas discharge through an annular duct which merges into a central cylindrical outlet, the air inlet ducts crossing the annular gas outlet duct. Leakage of combustion gases from the turbine passage to the compressor passage is prevented by causing air from a higher-pressure compressor stage to flow through the ring members 13 to a chamber between a ring member 13 and a corresponding ring member of the stator guide blades. The plant may alternatively be of the hot-air type having either an open or closed circuit, in which the air from the compressor is heated indirectly in a heat exchanger.
