Title: Improvements in or relating to the production of electric conductors
Inventor: HICKMAN PETER HENRY
IPC: H05K1/16
Filed: 1949-08-15
Abstract: 686,761. Photographically-produced resistances. NORTON & GREGORY, Ltd. Aug. 11, 1950 [Aug. 15, 1949; Jan. 11, 1950], Nos. 21150/49 and 739/50. Class 98 (ii). [Also in Group XXXVI] A process for the production of electrical conductors or resistances on an insulating support comprises exposing a light-sensitive layer to a transparency bearing an image of the conductors, said layer being applied before or after exposure to a conductive or resistive metal layer secured to an insulating support, removing selected areas of said sensitized layer, and etching the metal beneath said areas. According to one example copper foil is coated on one side with a resist layer of chlorinated rubber on which is provided a light-sensitive hydrolysed cellulose ester layer, which is then exposed to a transparency bearing a positive image of the required conductive pattern. The foil is bonded to an insulating backing before or after exposure. After exposure the exposed areas of the hydrolysed ester layer and the underlying areas of chlorinated rubber are dissolved away, the exposed areas of copper being then removed by etching. Finally the unexposed parts of the hydrolysed layer and the underlying chlorinated rubber layer are removed. The cellulose layer may consist of cellulose acetate which is hydrolysed by immersion in a solution containing sodium hydroxide, ethyl alcohol and water. It is light-sensitized by impregnation with a soluble chromate or bichromate. After exposure the exposed areas may be removed by immersion in sodium hypochlorite, aqueous sulphuric acid or sodium chlorite. In an alternative method the lightsensitive layer may comprise a bichromated glue, which is exposed under a negative transparency and sprayed with cold water to remove the unexposed areas. In a third method the light-sensitive layer comprises bichromated gelatine, obtained by immersing the gelatine in a solution of ammonium bichromate. This layer is exposed under a negative transparency and immersed in water at 110‹ F. to remove the unexposed areas In a fourth method the surface of the metal foil is coated with a cellulose lacquer over which a silver halide gelatine layer is applied by transfer sensitizing technique involving the use of a light-sensitive emulsion on dry stripping material. The emulsion is bonded to the lacquered surface after which the temporary support is stripped off. Prior to bonding the sensitive layer receives a flash exposure. The plate is exposed to a glass positive in a vacuum printing frame to form an image right through the emulsion. A high contrast developer consisting of sodium sulphite, potassium carbonate, " Glycin " (Registered Trade Mark), potassium bromide and water is used after which the plate is fixed in sodium hypo sulphite solution. The exposed areas of gelatine and lacquer are then removed to expose the unwanted portions of the metal foil which are then etched away.

Title: Improvements in or relating to the production of films
Inventor: BUTEUX RICHARD HAROLD BARCLAY
IPC: B29C48/90
Filed: 1953-07-31
Abstract: <PICT:0741963/IV(a)/1> In a process for the downward extrusion of thermoplastic tubular film and reduction of its wall thickness by inflating and drawing, the inflated tube is passed through a passage-way of circular section, at least at its entrance, down the walls of which flows a cooling liquid in contact with the external surface of the tubular film.  The cooling liquid is preferably supplied from a reservoir which surrounds the passageway and in addition the walls of the passageway may be hollow and be chilled by liquid circulating therethrough.  Cold water or a refrigerant may be used as the cooling liquid.  The films may be of linear superpolyamides and linear superpolyesters such as polyethylene terephthalate.  As shown, a tubular film 2 is extruded from nozzle 1 and is inflated by air introduced through pipe 3.  The inflated tube passes into a passage-way 6 bounded by wall 7 down the interior of which flows cooling liquid from bath 4.  The wall 7 is surrounded by a barrier 8 having orifices 11 for the passage of cooling liquid, the height of the barrier being adjustable by means of its threaded mounting 10.  The tubular film then passes between a pair of flat plates 12 hinged to the bottom of bath 4; the plates are of metal which may be highly polished, etched or coated with polytetrafluorethylene. The nip rollers 13 are driven at adjustable speed and one is preferably rubber coated.  The flattened film is drawn off through a bath 15 having an adjustable outlet 16, although it is not necessary for bat 15 to contain any water, other than water entrained by the film.  If desired, the tubular film may be slit by a knife before it reaches nip rollers 13, in which case the nip rollers and knife are immersed in the bath, the water pressure being sufficient to confine the air within the inflated portion of the tube.

Title: Improvements in high-pressure and high temperature lubricants and methods of lubrication
IPC: F16N17/00
Filed: 1935-08-02
Abstract: A lubricant adapted for high-pressure and high-temperature use comprises finely-divided particles of organic material dispersed in mineral oil.  Specified organic materials are polymerized and/or oxidized oils, e.g. tung, linseed, soya bean, castor and corn oils, and mixtures; vulcanized rubber and castor, soya bean, corn, linseed and tung oils; oxidized asphalts and petroleum resins; insoluble, high-melting soaps, e.g. the aluminium soap of polymerized tung oil; lignin; fatty-acid pitches; and insoluble, high-melting synthetic and natural resins, e.g. coumarone-indene resins.  The particles may be ground up with or formed in the oil vehicle.  If the particles are not self-sustaining, auxiliary particles may be employed to form a stable suspension, e.g. a soap such as aluminium stearate or sodium oleate may be dissolved, with heat, in mineral oil, cooled to form a gel, and agitated to produce finely-divided gel particles through which the lubricant-particles are distributed.  Carnauba wax may be used. In examples: (1) and (2) tung oil dissolved in light petroleum oil is oxidized in the presence of a catalyst, e.g. cobalt naphthenate, by continuous circulation and agitation in contact with air; (3) powdered lignin is dispersed in light petroleum oil gelled with carnauba wax; (4) vulcanized corn oil, produced by treating corn oil dissolved in carbon tetrachloride with sulphur monochloride, is crushed to powder and ground with an equal volume of petroleum oil. A machine for testing lubricants is also described comprising a lower vertical chuck carrying three stator balls of carbon steel surrounded by a lubricant cup, and an upper aligned chuck carrying a single ball of chrome steel and adapted to be rotated by an electric motor.  The lower chuck is movable vertically, e.g. by an hydraulic piston, to apply pressure and is mounted upon ball bearings so as to be free to turn.  In use, the cup is filled with lubricant, the upper chuck is rotated and the lower chuck is raised to apply pressure, sufficient torque being applied to hold it against rotation.  After the test, the area of wear on the lower balls is measured, and the load-sustaining capacity of the lubricant is computed from the bearing surface and the load.

Abstract: A process for the production of carbides, borides or silicides of elements of Group 3a and 4b of the Periodic Table according to Mendel<\>eeff wherein a charge comprising an intimate mixture of the raw materials from which the desired compound is formed is heated in an electric furnace is characterised in that there is incorporated in the mixture an additive consisting of an alkali or alkaline earth metal, or a compound of an alkali or alkaline earth metal, preferably in an amount of 0,01%-0,3% by weight, to increase the electrical conductivity of the vapour phase in the electric arc.  A rare earth metal or compound may be used in place of or in addition to the above referred to additives.  The mixture may be used as such, or may at least in part be moulded with the additive (either dry or moist) into lumps.  In examples (1) boric acid and petroleum coke are mixed with caustic soda solution, formed into flat cakes, dried, and broken into pieces, and these pieces are then fed to an electric furnace, containing a bed of fused boron carbide, to give boron carbide, (2) sand and water glass are mixed with water, dried, broken up into lumps, and fed into the arc furnace to produce silicon carbide, and (3) boric acid, sand, carbon black, and caustic soda were mixed together with water, dried, broken up into lumps and fed into the furnace to obtain a uniformly fused block of the composition 23,5%C, 28,5%Si, 47,8%B.  Aluminium boride may also be made.
