Title: Improvements in or relating to the manufacture of interpolymers of aromatic vinyl hydrocarbons with other polymerisable organic compounds and of coating compositions obtained therefrom
IPC: C08G67/00
Filed: 1942-07-28
Abstract: Interpolymers suitable for use as coating compositions for motor car and aircraft finishes, insulating, adhesive and laminated materials, printing inks and moulding compositions, are made by partially polymerizing by heat one or more polyhydric alcoholic mixed esters (other than the products obtained by heat blending a frosting drying oil with a varnish gum or resin), adding an aromatic vinyl hydrocarbon and polymerizing the mixture alone or in the presence of a solvent and/or a catalyst.  Styrene is the preferred vinyl hydrocarbon.  The polyhydric alcoholic mixed ester is an ester of a single polyhydric alcohol and a mixture of acids containing a substantial proportion of at least one unsaturated fatty acid. Specified polyhydric alcohols are glycerol, pentaerythritol, mannitol and sorbitol.  Specified unsaturated fatty acids are the fatty acids of drying, semi-drying and non-drying oils and the acids of rosin and copal. The partial polymerization of the ester may be carried out between 150 DEG  C. and 300 DEG  C. and may be in the presence of a catalyst, e.g. air, oxygen, benzoyl peroxide, sulphur dioxide, metallic soaps, anthraquinone.  For the final polymerization solvents are toluene, xylene, ethyl benzene, mineral spirits and turpentine; specified catalysts are benzoyl peroxide and air.  In a modification, the mixed ester is obtained from one of the above acids together with a dibasic acid or anhydride; maleic and phthalic acids are specified, also, if the mixed ester contains no frosting drying oil, it may be heat-blended with a natural gum or resin before inter-polymerization with the vinyl compound. Specified mixed esters are linseed stand oil, dehydrated castor oil and esters obtained from glycerol, linseed oil fatty acids and phthalic anhydride.  In examples, styrene (1) in xylol is polymerized with partly polymerized (a) linseed stand oil and (b) dehydrated castor oil; (2) is polymerized with heat-treated dehydrated castor oil in (c) turpentine and (d) mineral spirits; and (3) in xylol is polymerized with a mixture of (a) and (b).  In (5), phthalic anhydride, glycerol and linseed oil fatty acids are heated and the product together with styrene dissolved in xylol and polymerized.  Specifications 552,095 and 552,096 are referred to.

Preferably the process is continuous and the resin from reactor 11 is purified in the stripper chamber 13, the pH is adjusted in chamber 17 and the latex mixed with the plasticizer dispersion in chamber 21.  The emulsifier for the plasticizer dispersion may be selected from long chain alkyl sulphates and sulphonates, aryl and alkaryl sulphonates, fatty acid soaps, rosin acid soaps, condensation products of an alkyl phenol and ethylene oxide, heptadecyl-amine-epichlor-hydrin and dodecylamine hydrochloride.  The latex may be used as such or coagulated to give a plasticized resin. Examples describe the appearance and stability of various compositions.

A gas-diffusion electrode is prepared by applying a fluorocarbon resin in powder form to the gas face of a porous sintered plaque containing a major proportion of nickel powder. The powder may be bonded to the plaque by heating the electrode to a temperature below the melting point of the resin. The plaque may be made from grade A carbonyl nickel with grade B carbonyl nickel if necessary, to give a porosity exceeding 70%. Possible additives are: up to 13 wt. per cent activated charcoal, up to 4 wt. per cent acetylene black, 3-7 wt. per cent Al 2 O 3 , and 5-7 wt. per cent of a pore-forming agent, e.g. urea or naphthalene. The electrode may be used alone or with known catalysts, and may be given a conventional water-repelling treatment before application of the fluorocarbon polymer powder, e.g. using a polyethylene, polystyrene or fluorocarbon resin emulsion. Suitable powdered resins include PTFE. polychlorotrifluoroethylene and tetrafluoroethylene / hexafluoropropylene copolymer. In examples an electrode is prepared from carbonyl nickel sintered with acetylene black or activated charcoal on to a nickel mesh, then treated with AgNO 3  and alkaline formalin to give silver, impregnated with a fluorocarbon resin emulsion, heated to 340‹ C., then dusted with tetrafluoroethylene/ hexafluoropropylene copolymer; this is used as oxygen or air electrode in H 2 /O 2 , methanol/air or hydrazine/air fuel cells. A similar electrode having alumina in place of the carbon, and a Pt catalyst, is used as a hydrogen electrode. In the hydrazine/air cell a polyvinyl alcoholimpregnated PVC separator is inserted between the electrodes.

Abstract: 527,391. Acetylene. I. G. FARBENINDUSTRIE AKT.-GES. April 11, 1939, No. 10951. Convention date, April 12, 1938. [Class 2 (i)] In a process for preparing acetylene by treating calcium carbide with a limited amount of water so that the calcium hydroxide formed is obtained essentially in the dry state, further carbide is added to the reaction mixture shortly before the end of the process in order to remove excess of moisture. Any undecomposed pieces of carbide still contained in the residue which have not been used in drying the hydroxide are separated for instance by screening. The amount of further carbide added may be automatically regulated in dependence on the content of moisture in the mixture of carbide and hydroxide. For instance when a certain maximum limit of moisture has been obtained as detected by electric contacts an electric circuit is closed to start the device for additionally charging the generator with carbide.

Title: Nuclear chain reacting systems
IPC: H02P3/24
Filed: 1945-05-02
Abstract: 817,752. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 2, 1945 [May 4, 1944], No. 11190/45. Drawings to Specification. Class 39(4). The neutron reproduction factor of a proposed chain reacting structure is determined by neutron density measurements on an experimental pile structure. The latter is a small, dimensionally similar, representative combination of uranium bodies, embedded in a neutron retarding material, such as carbon. The structure has a neutron source near the base and an arrangement of channels which penetrate into the interior to facilitate the insertion of a neutron detecting device. The later is an indium foil mounted in a carbon holder, slidable in the channels. The foil radio-activity is a measure before and after exposure to the experimental pile neutron flux and the difference is a measure of the flux. The relative concentration of neutrons of different energies in the experimental pile is determined by inserting the foil, first enclosed in aluminium and secondly in cadmium. The ratio of the radio activities induced in the two cases provides the required relation. The neutron source, employed to provide measurable neutron densities within the pile, consists of radium and beryllium and is disposed in a capsule in the paraffin slab forming the pile base.

A motor-vehicle main clutch comprises a clutch plate 25 connected to the output shaft 28 through a forward-drive one-way clutch 27, and engaged with an input flywheel 23 by centrifugal means 24 mounted on the latter; together with a second output-mounted clutch plate 29, engageable at will directly with the input flywheel 23, as by energizing an electromagnet 31, means, such as a grip-actuated switch, being provided on the usual gear-shift lever P for disengaging the controllable clutch 29 during gear shift. The controllable electromagnetic clutch 29 is required to transmit only overrun torque. The clutch 25 is engaged in opposition to springs 21a by centrifugal force acting on balls 24 in two relatively axially movable cups 21, 22 carried by the input assembly 23, 30. The balls 24 may be divided into sectoral groups by radial vanes on a loosely inserted member 50 as described in Specification 855,660. In the electromagnetic clutch the driven disc 29 may be of soft or non- magnetic steel and separates the axially fixed armature 30 of the input assembly from the spring-retracted axially movable magnet yoke 31. A control circuit for the electromagnetic clutch M, Fig. 2, comprises a contact bridge 43, which, on accelerator depression beyond a position at which the centrifugal clutch would normally be engaged, through linkage C, bridges contact 41 to energize the clutch speedresponsively from an engine-driven generator D. Operation of the gear-shift lever P energizes from a battery B a solenoid 44 which draws down the contact bridge 43, breaking the clutchenergizing circuit and making hold-on contacts 42 to maintain energization of the solenoid until the contact bridge 43 is raised by accelerator depression. Closing a switch A energizes the clutch M directly from a battery for push start.
