Title: Improvements in or relating to impregnating and adhesive compositions and impregnated and laminated articles and materials made by use thereof
Inventor: YARSLEY VICTOR EMMANUEL
IPC: C09J167/06
Filed: 1950-06-09
Abstract: A composition for laminating and impregnating purposes comprises a solution in styrene and/or a nuclear alkyl and/or halogen substituted styrene of a polyhydric alcohol polyester of itaconic acid and a saturated polybasic acid, and an N - di (lower alkyl) aniline, e.g. N - dimethyl and N - diethyl aniline. in amount not exceeding 1 per cent. by weight of the composition. An inhibitor, e.g. hydroquinone and hydroquinone dimethyl ether, is preferably added.  Before use, a peroxide catalyst, e.g. benzoyl peroxide, is also added.  The polyhydric alcohol component of the polyester may be ethylene-, diethylene- or propylene glycol.  The preferred polybasic acid is phthalic acid.  The polyester is prepared by heating the alcohol with a chemically equivalent amount of the two acids, or a slight excess of alcohol may be used, and the mixture is stirred under a stream of inert gas.  Laminates are formed by impregnating or coating the surfaces to be joined and effecting copolymerization, if necessary with the aid of heat.  The composition may also be used for insulating windings in motors and dynamos.

Filed: 1935-05-20
Abstract: 435,377. Printing. OXVAR, Ltd., 3, Lower Regent Street, London.-(Assignees of Webern, G. von) May 20, 1935, No. 14660. Convention date, June 14, 1934. [Class 100 (ii)] A method of decorating blanks having non- planar surfaces consists in transferring a pattern from a pattern plate to a printing-matrix having a non-planar surface, and from the matrix to the blank to be decorated, the surface of the matrix having a contour dissimilar to both pattern plate and blank but intermediate of these. A driven roll having a core 14 of metal or wood has a V-shaped periphery 15 of resilient material such as rubber, or a glue and glycerine compound, such periphery being inherently tacky, the roll being first brought into rolling contact with a flat-inked pattern plate, or a plainsurfaced pattern cylinder, whereby the periphery of the roll is compressed and flattened at the centre 21 to pick up the inked pattern, and then brought into contact with an article W having an angular recess a to be decorated. The periphery 15 is shaped so that it enters only partially the recess a, preferably half-way, and pressure is applied to the shaft of the roll to compress the periphery at the sides thereof so that the periphery engages all parts of the recess a. Modifications are described in which the periphery of the roll has a concave, convex, or an irregular contour, but in each instance the periphery normally extends mid-way into the depressions in the object to be decorated.

Filed: 1953-05-26
Abstract: 736,732. Laminating-apparatus. ROBERTSON THAIN, Ltd. (Robertson Co., H.H.). May 26, 1953, No. 14661/53. Class 140. [Also in Group XVI] Apparatus for uniting one or two fibrous webs to a continuously travelling, adhesivecoated metal strip comprises means for detecting and correcting misalignment of the side edge of a fibrous web with the corresponding edge of the steel strip. A steel strip 10 that has been passed through a molten metal adhesive and through a heating chamber 'is united between pressure rollers 18 and 20 with cover webs 22 and 24 of asbestos paper or felt. Web 22 is supplied from a roll 26 which is mounted on a wheeled carriage 30 adapted for movement in the direction of the central shaft 50 of the roll. From roll 26 the web passes over guide roller 120, over gas jets 34, around guide roller 102, which is mounted on a wheeled carriage 40 for movement parallel to the roll 26, through a misalignment-testing device 134, and around guide roller 124 to the bite between rollers 18 and 20. Lateral wandering of the web is detected at 134 by passing its edge through a gap between two opposed air nozzles 142 and 144 one of which is connected to a source of compressed air and the other to one side of a spring-biased, pressure-responsive diaphragm. Lateral wandering of the edge of the web thus brings about a movement of the diaphragm which is used to control the flow of a hydraulic fluid to a cylinder, and consequently to impart the necessary corrective movement to the carriages carrying the web-supply and guide rollers from a piston sliding in the cylinder. The lateral position of web 24 is controlled similarly. Specification 467,142 is referred to.

Abstract: 1,148,165. Making alloy powders. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. April 1, 1966 (April 8, 1965], No. 14662/66. Heading C7D. Alloy powders are produced by heating a mixture of two or more ultrafine powdered metals and an inert diluent material in an atmosphere containing hydrogen and a halogen and optionally removing the inert diluent material. At least one of the powdered metals must have been made by reduction of a metal compound (e.g. oxide, formate, oxalate or carbonate in the presence of an inert-diluent at 900-1100 C. The inert diluent, which prevents the powder particles from coalescing, may be CaO, MgO, BaO, or A1 2 O 3 , may have been formed prior to, or concurrent with, the reduction of the metal compound and is preferably present in the amount of 25 vol. % of the powder mixture. The inert diluent may then be removed if desired by the action of a dilute acid, by magnetic separation or by means of differential density. The mixture may contain some magnesium filings to trap any excess oxygen in the heating step.

Title: Improvements in the heat treatment of metals
IPC: C21D1/10
Filed: 1942-10-21
Abstract: 569,005. Electric induction heating. RADIO CORPORATION OF AMERICA. Oct. 21, 1942, No. 14784. Convention date, Dec. 5, 1941. [Class 39 (iii)] Metals are hardened by heating the surface by high frequency induction to a predetermined temperature substantially simultaneously and to a very small depth, and then quenching the heated layer by conduction through the backing layer. A high frequency generator 1 supplies current to an inductor ring 5 through a transformer 3 which may be a coil of concentric transmission line the inner conductor forming the primary. The ring 5 may be a water cooled tube and is shown applied to the cylinder bore 9 of an engine block 7, which is mounted on a platform 11 moved vertically by gearing rotated by a motor 23. The frequency may be 100 kilocycles, the ring 5 may be #inch thick, and power may be delivered to the work for .075 sec. or at the rate of 5K.W. per sq. cm. The block 7 may be moved at about 1¢ inches per second. The cylinder walls are thereby heated to 950 ‹C. to a depth of 0.02 inch. Heat is dissipated into the metal backing the heated skin at about the same rate as that at which it is applied. If the metal to be hardened is thin, it may be backed temporarily by Wood's metal or solder. The method may be applied to articles such as gear wheels or shafts by means of an external inductor ring. The method may be applied to ferrous and other metals, and to the annealing of metals, e.g., brass. The ring 5 need not be movable.

Title: Improvements in or relating to nuclear reactors
Inventor: PRATT HENRY REGINALD CLIVE
IPC: G21C1/20
Filed: 1957-05-13
Abstract: 849,225. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. May 8, 1958 [May 13, 1957], No. 15130/57. Class 39(4). [Also in Group XII] A coolant for nuclear reactors consists of a suspension of a liquid in a gas, preferably in its own vapour. Vertical tubes 1 contain fuel elements 2, 2a and have a vapour-liquid separator at the outlet end of each tube. The vapour leaving the separators is superheated in further tubes 1a and used to drive a turbine before being recirculated. The suspension is produced by a Venturi throat 4 at the entrance to each tube ; each tube contains a cluster of fuel rods 2, 2a. Headers 15a contain steam and water separated by tangential feed of wet steam through pipes 18a. Pipes 22 dip into the water in these headers and Venturi action draws water into ring manifolds 6 and through radial feed pipes 5 into the Venturi throat 4. The water and steam may be fed to the tube via a liquid trap 25a, Fig. 8. The separator may be a simple liquid trap. A simpler form of tube, Figs. 1, 4 (not shown), dips into a reservoir of water in contact with the underside of the core so that the water boils at the lower ends of the tubes. In a reactor the tubes may be arranged in concentric zones with the vaporising tubes surrounding the superheaters or vice versa. The vaporising tubes may also be divided into concentric zones, the tubes in each zone being fed from annular headers 15a or ring mains 40. The feedwater returned from the turbine may be heated in a heat exchanger used for cooling the moderator. Specifications 735,851 and 795,406 are referred to.

Filed: 1928-05-23
Abstract: 309,767. Hoe & Co., Ltd., R., (Hoe & Co., Inc., R.). May 23, 1928. Tripping-arrangements.-In a rotary intaglio printing-machine in which two printing-couples are employed, means are provided for simultaneously raising and lowering the bearings 21 of one of the printing members, or for raising and lowering them individually, and for adjusting independently each end of the cylinder, the whole bearing-adjusting mechanism being unyielding. The bearings 21 are formed with cylindrical extensions 22 mounted in carrier frames 23, keys causing the extensions 22 to move longitudinally only. Each extension 22 is connected to a screwed rod 32 by means of a worm wheel 30 screwed on the rod and arranged between a cap 26 secured to the extension 22 and a block 100 arranged in a recess 30'. The rods 32 are connected by turnbuckles 34 to other screwed rods 36 which are engaged by threaded worm wheels 37 engaged by worms 42 on shafts 43, and are prevented from rotary movement. A common driving- shaft 47, Fig. 1. is geared by bevel gearing 46 to the shafts 43, so that the worm wheels 37 can be simultaneously rotated, and the rods 36 moved vertically to adjust the cylinder bearings. By adjusting the turnbuckle connection between the rods 36, 32, the pressure at each end of the cylinder can be controlled. For adjusting each cylinder independently of the others, the worm wheels 30 are operated by worms 31 on a shaft 28 extending across the machine, and the threaded connections between the wheels 30 and rods 32, which are prevented from rotation, cause a vertical displacement of the wheels 30 relatively to the rods 32, and also a correspond ing movement of the bearings 21. The bevel gears 46 are operated by a shaft 47 driven by a chain 48 from a motor 49. The driving of the motor is controlled by a limit switch which cuts out the motor when the cylinders have been adjusted to the desired extent. After the cylinders are tripped for any reason, they can thus be returned accurately to their former position.
