Filed: 1927-12-02
Abstract: 311,788. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 2, 1927. Addition to 309,200. Alcohols.-In the process for the production of mono-and polyhydric alcohols by catalytic reduction with hydrogen of the condensation products of aldehydes or ketones or both described in the parent Specification, the condensing agent is removed from the condensation product prior to the reduction, either by precipitating the condensing agent with a suitable precipitant, such as sulphuric, oxalic or carbonic acid, or by purecipitating the condensation products, for instance in the form of saccharates, by adding metal oxides or hydroxides, especially alkaline earth oxides or hydroxides, or by extraction of the condensing agents or the condensation products with solvents such as water or alcohols. The condensing agents may be compounds of magnesium, barium, strontium, calcium, lithium, or lead, for instance the oxides, hydroxides, basic salts and salts with weak acids such as carbonates and formates and the catalysts for the reduction may be metals of the 1st and 8th groups of the periodic system, preferably with the addition of activators such as the oxides, hydroxides silicates and phosphates of the same or other elements, and preferably with a carrier such as kieselguhr or fullers' earth. In an example, a 3 per cent solution of formaldehyde is heated and stirred with lead hydroxide at 100‹ C. for an hour and after removing the undissolved lead hydroxide the dissolved lead is removed by adding dilute sulphuric acid; the filtrate is concentrated and reduced by hydrogen in presence of an activated nickel-kieselguhr catalyst, the products containing penta- and hexa-hydric alcohols together with glycol and glycerol. In another example, a 4 per cent solution of formaldehyde is heated and stirred with magnesia at 130‹ C. for 1¢ hours; the reaction mixture is concentrated to a syrup and the condensation product is extracted with alcohol, the solution being reduced with hydrogen at 25 atmospheres with a nickel-fullers' earth catalyst containing 40 per cent of nickel, which has been reduced in hydrogen at 450‹ C. The product is a mixture of polyhydric alcohols including glycol and glycerol, which are separated by distillation in vacuo.

Title: Method of manufacturing metal bonded abrasive gear hones
IPC: B24D18/00
Filed: 1964-08-11
Abstract: A metal bonded abrasive tool, for example a gear honing tool, is made by forming a mould having a surface conforming exactly to the required form of the tool, positioning a metal body in juxtaposition to said mould to leave a relatively thin continuous space therebetween, solidly packing said space with irregularly shaped abrasive particles, for example tungsten carbide, and thoroughly wetting the mass of particles with a fluid interim binder such as water glass or aqueous polyvinyl alcohol, causing the binder to harden, for example by heating, removing the mould, applying a metal matrix material, for example copper, or an alloy such as copper-tin, to the body adjacent to the abrasive, and heating the assembly to melt the matrix to cause it to flow into the voids between the particles and to provide a permanent bond between contiguous particles and between the particles and the body.

Abstract: 393,311. Alternative prime movers. ARMSTRONG, WHITWORTH, & CO. (ENGINEERS), Ltd., SIR W. G., Thames House, Westminster, and BECKETT, C. M., 55, Wordsforth Drive, Cheam, Surrey. Nov. 25, 1931, No. 32692. [Class 79 (iii).] In an engine-electric propelling system for vehicles, the engine 1 is connected through a relatively small friction clutch 2 with a reduction gearing 3 and the motor 5, operated through a controller 6 by a storage battery 7, is connected to the reduction gear so as to be always in driving relation therewith at least in one direction, the reduction gear being in driving relation through a reverse gear 4 with the vehicle axle or axles. A variable speed reduction gear may be employed and the connection between the motor and the reduction gear may be through a one-way clutch 8. The arrangement enables the motor to be used to start the engine and then, with the engine idling, to start the vehicle, the engine subsequently being brought in and taking over the drive with the motor regulated so as to " float " on the battery, helping the engine or regenarating current as occasion demands. The controls may be provided with interlocks, such as between the reverse control and the controller 6. The Provisional Specification describes also an arrangement wherein the motor is connected to the reduction gearing through a friction clutch which may be disengaged by the driver at will.
Patent GB-725790-A (GB)
Title: Nitration process
Filed: 1953-11-25
Abstract: Alpha-naphthylamine is nitrated by adding a mixture of concentrated nitric acid and concentrated sulphuric acid to a solution of alpha-naphthylamine in concentrated sulphuric acid, maintaining the temperature of the reaction mixture between -10 DEG  C. and -25 DEG C. while the reactants are being mixed together, and providing constant, vigorous agitation.  To facilitate mixing the nitration mixture is added as a fine spray.  The formation of tars and decomposition products is minimized by removing the nitro-naphthylamines from the nitrating agent promptly, and this is done by pouring the mixture on to crushed ice.  The 5-nitro-1-naphthylamine sulphate is precipitated, and the 8-nitro-1-naphthylamine sulphate is recovered from the ice-water slurry.  In the example yields of 60.5 per cent of 5-nitro-1-naphthylamine and 33.2 per cent of 8-nitro-1-naphthylamine are obtained.

Abstract: 1350856 Weighing-out material TRAYVOU S A 13 July 1972 [21 July 1971] 32826/72 Heading G1W To weigh-out material, e. g. in powder or granulated form, in doses of equal weight despite possible density variations, the material is first delivered to weighing apparatus at a first constant rate by volume until a predetermined major portion of the desired dose has been delivered, and then the remaining minor portion is delivered at a reduced constant rate by volume, the reduced rate being automatically determined as a function of the time taken to deliver the major portion. Therefore the mass flow-rate of the minor portion is equal for all doses even if the density of the material varies from one dose to the next. At the start of delivery of material from hopper 2, a cam 15 is set rotating by an electric motor and moves a lever arm 18 downwardly as time progresses. When the predetermined major portion has been delivered the motor stops the cam and a jack 7 is actuated to lower a screen 4 and a shutter 8 into the path of the material to partially block its flow, an opening 41 in screen 4 being more or less obscured by the shutter 8 according to the position of the arm 18 and thus the time during which the cam 15 has been rotated. Materials of different densities, particularly hygroscopic materials such as detergents or powdered milk, can be catered for by regulating the angular speed of cam 15 using variable reduction gearing.

Filed: 1948-12-21
Abstract: 650,216. Bonding rubber to steel. SANDVIKENS JERNVERKS AKTIEBOLAG. Dec. 21, 1948, No. 32970. Convention date, Jan. 7. [Class 70] [Also in Group VIII] Rubber-coated steel is continuously produced by conveying a preheated steel strip and a rubber strip coated with a thermosetting resin along converging paths and then providing sufficient pressure in conjunction with that produced by a dielectric field to cure the rubber and set the cement between the strips. In a preferred apparatus a steel strip 1, which may be copper plated, passes between the nozzles 4 of sandblasters 6 and then through a heater coil 20. At the same time rubber strips 8 and 10 pass the applicators 24 of spray or brushing devices 26 which apply a coating of a thermosetting cement, the setting temperature of which is substantially the same as the curing temperature of the rubber stock. The three strips then run together over guide rollers 28 and 30 where they are subjected to high-frequency oscillations from electrodes 32 and 40 respectively. Finally, the rubber-coated steel passes between pressure rollers 50 and 52 which may be heated by radiation, e.g. by infra-red rays, which completes the bonding and curing of the rubber.
