Title: Process for the manufacture of Shaped Articles
IPC: C08G18/02
Filed: 1967-05-19
Abstract: 1,172,255. Coated substrates. KALLE A.G. 19 May, 1967 [21 May, 1966 (2)], No.23431/ 67. Headings B2E and B2K. [Also in Division C3] Coatings are obtained from compounds having at least two aromatically bonded isocyanate groups in the molecule which are homopolymerized in certain polar solvents which are at least partially miscible with water and does not contain groups with active hydrogen atoms, the reaction mixture being coated on the support while still flowable and then allowed to solidify by completion of the reaction. The solvent is such that it complies with the condition where 8 is its solubility parameter, # is its dielectric constant and LM is the solubility of the isocyanate in the solvent in grams per 100 grams of solvent. Suitable solvents are dimethylsulphoxide, butyrolactone, pyridine, acetonitrile, methylethyl ketone, isophorone, tetramethylene sulphone and nitrobenzene; N, N-dialkyl carboxylic acid amides are excluded. The reaction mixture may become solid without loss of solvent and the solvent may be removed subsequently, e.g. by washing with water, or the solvent may be removed as the polymerization occurs. A basic catalyst, a radical-forming catalyst or a catalyst with an oxidizing effect may be used and the reaction may be irradiated with ultraviolet light. Iodine, sulphur or an acidic material, e.g. aluminium trichloride, may be added to retard the polymerization. In Examples polymers obtained from diphenylmethane-4, 4'-diisocyanate and diisocyanates obtained by reacting 2, 4-toluenediisocyanate with adipic acid-ethylene glycol polyesters, the solvents being dimethyl sulphoxide and butyrolactone, and the catalysts being potassium bichromate, potassium permanganate and aluminium triethylate, are coated on glass, cotton fabric and polyethylene terephthalate film. Other supports mentioned are metals, plastics, felts, fleeces and paper.

Abstract: 901,798. Valves. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 5. 1960 [July 8, 1959], No. 23547/59. Class 135, [Also in Group XXVI] Fluid flow through a duct is controlled by vanes disposed within the duct so as to be rotatable about axes extending radially outwardly from the longitudinal axis of the duct, the vanes being connected to pinions meshing with a toothed wheel mounted on a shaft for rotation about the longitudinal axis, and means being provided for rotating the shaft. Gaseous coolant is circulated through a nuclear reactor and a heat-exchanger by means of a centrifugal impeller 2 disposed within the heatexchanger shell 3. Six vanes 4 are pivotally mounted within a convergent inlet duct 1 by means of stub shafts journalled in ball-bearings 62 carried by a centre body 5 and roller bearings (not shown) carried by the wall 21 of the inlet duct 1. The vanes 4 are adjustable between the fully open position shown and a position in which they abut at their side edges and substantially obturate the duct 1. The adjustment is effected by a reversible electric motor 77 connected by an overload coupling 78, shafts 74 and 23 and bevel gearing 47, 35 to a shaft 22 which is connected to the vanes 4 by bevel-wheel 41 and bevel pinions 66.

Title: Directional indication and control means for dirigible craft
IPC: G01C19/00
Filed: 1937-08-27
Abstract: 501,363. Fluid - pressure servomotorcontrol systems. FLOREZ, L. DE. Aug. 27, 1937, No. 23549. Convention date, Aug. 28, 1936. [Class 135] A system for controlling the movement of a dirigible craft, more particularly an aircraft, according to the rate of deviation of the craft from its course comprises a gyroscope 7 responsive to the rate of deviation which controls a valve 13 which regulates suction, from, for example; a vonturi 28 in the airstream, through conduits 29, 30 to diaphragms 57 and 58, Fig. 3, of a relay valve 31 which regulates the suction on the two sides of a servomotor piston 48 actuating the rudder 51. The relay valve 31 comprises a central part 35 which controls the suction from ports 36, 37 of suction conduit 27 to conduits 45 and 46 leading to the two ends of the rudder motor 47, and two end parts 38, 40 controlling ports 39, 41 which communicate with chamber 42 and the atmosphere. With the valve in the intermediate position as shown, the pressures on the diaphragms 57 and 58 being equal, the pressures on opposite sides of the piston 48 are equalized and the rudder maintained in its central position. On unbalance of the pressures on diaphragms 57, 58 the valve member 35 is moved to vary the pressures on the servomotor piston to move the rudder 51 and bring the craft back to its course. To overcome " hunting " tendencies restrictions 66, 67 and capacity chambers 68, 69 are introduced into the conduits 29, 30 between the control valve 13 and relay valve 31, so that a modification of the pressures in the lines 29, 30 is obtained which is stated to be in proportion to the amount of deviation of the craft. For indicating purposes a gauge 32 subjected to the pressures in the conduits 29, 30 from the control valve 13 is provided which gives rate of turn indications whilst a second gauge 33 subjected to the same pressures but modified by restrictions 70, 71 and capacity chambers 72, 73 is used for indicating the amount of turn. Specification 471,537 is referred to.

A dust separator consists of a vessel 1 for holding liquid, e.g. water, a gas inlet tube 5, 6 located so that the dust-laden gas entering the vessel is directed normally to the liquid surface, a plurality of tubes 12 arranged laterally of the gas inlet and also normal to the liquid surface so that the gas impinging on the liquid surface entrains liquid droplets and flows upwardly through said lateral tubes, and deflection plates 14 above the lateral tubes to separate the droplets from the gas stream, which leaves through outlet 7, and return them to the main body of the liquid. The vessel I may have a sludge outlet 3.
