Title: Improvements in insulated electric conductors
IPC: H01B7/36
Filed: 1948-04-16
Abstract: An insulated electric conductor having a continuous layer of fibrous glass is coloured by passing it through a bath containing a suspension of an organic colour in a volatile liquid and then upwardly from the bath through a device which wipes the surface of the layer over the whole of its circumference.  Suitable colouring baths are obtained by dissolving in methylated spirit one of the dyestuffs used in rubber compounding, e.g. Vulcafor Red 2RS, Monastral Blue BS, Monastral Green LS, or Vulcafor Yellow GTS, and if desired, adding a small amount of an aqueous solution of an acid dyestuff.  The conductor may then be covered with a layer of clear cellulose acetate lacquer.

Title: Improvements in electrical condensers
IPC: H01G4/228
Filed: 1926-04-23
Abstract: 263,736. Dubilier Condenser Co. (1925), Ltd., (Assignees of Dubilier, TV.).- Dec. 29, 1925, [Convention date]. Condensers. - Various forms of condensers mounted in containers with closure members and having projecting terminals are described. In the form shown in Fig. 10, the stack 1 is mounted in a receptacle 2 which is preferably of metal open at the top to receive the lid 3 of insulation. Terminals 4, 5 project through the lid and engage opposite poles of the stack which is insulated from the receptacle by a lining 11 and is held in place by forming a rim 17. The stack is formed of the usual interleaved foil and insulating sheets and subjected to pressure and exhausted prior to treating with liquid insulation such as melted wax. The receptacles may be made by punching and of uniform size to accommodate various capacities the space not occupied by the stack being filled with insulation. The lining may cover the bottom and sides or the sides only of the receptacle and may be of rubber, varnished cloth, wax paper or other insulating material. The terminals 4, 5 have a base 14 engaging the underside of the closure and a shank 15 extending through it and formed by slitting the base and bending the shank at right angles so that the base will lie on the projecting parts 9, 10 of the foils. The base may be bowed (Fig. 9) and serrated to give a better contact, and a bowed spring 13 may also be provided for the same purpose, disposed between the bottom of the receptacle and the lining. The terminals are also made strong and springy so that they can be bent to secure the condenser in any desired position or to receive a tubular grid leak resistance. In the form shown in Fig. 13, the lid 26 is of metal and apertured to receive rubber bushings 27 through which pass the terminals, 25 being a mice sheet. If it is desired to use the receptacle as one terminal of the condenser, the lining is made to cover the sides only and half the foil sheets are bent under the stack to engage the bottom, or alternatively half the foil sheets may be arranged to be exposed through the lining and a bushing such as 27 may be carried by the bottom of the receptacle and receive a terminal engaging those sheets. In Fig. 19 the receptacle is provided with an insulating sheet 31 covering two opposite sides, a foil sheet 32 thereon engaging the remaining sides, and a flat sheet of foil 33, the insulation 31 preventing contact of the terminals of the stack with the receptacle and the foil of the stack being too narrow to contact with the foil 32. In this way the strip 31 is free from electrostatic stress and insulation bosses as the strip 32 ensures the same potential on both faces when the receptacle is at a potential. Two or more sections may be put in series or parallel in a receptacle to give different capacity values, connection being made if necessary by means of extra foil sheets between the sections.

Abstract: <PICT:0743080/III/1> A nitrating acid is obtained by dissolving the crystalline nitronium hydrogen pyrosulphate or nitronium hydrogen disulphate (NO2+)(HS2O7-) in at least 40 per cent nitric acid in amount insufficient to reduce the proportion of nitric acid in the mixture below 30 per cent.  Sulphur trioxidecontaining gas is passed at 4 into packed absorption column 1 countercurrent to an absorption liquor having a molar ratio of SO3 : N2O5 of about 4, e.g. 3.8, and kept at over 100 DEG C.  The absorption liquor is continously circulated from buffer tank 2 at 110-120 DEG C. by pump 3.  Liquor is withdrawn in amount corresponding to the amount of supplied ingredients absorbed, from tank 2 at 6 to a vessel having a drum cooler 7 whereon the (NO2 +)(HS2O7-) crystallizes.  The crystals may be divided into two parts and passed by conveyers 8 to reservoirs 9, 11 wherein they are dissolved in conc. nitric acid to form make-up liquor and nitrating acid respectively.  The liquor in reservoir 9 is adjusted to have a composition 0-2 parts H2O, 35-50 parts SO3, and 65-50 parts HNO3, and is returned to tank 2 by pump 10.  The proportions of make-up liquor and absorbed sulphur trioxide are such that the molar ratio of SO3 : N2O5 in the absorption liquor is maintained at about 4.

Patent GB-469007-A (GB)
Title: Manufacture of compositions containing cellulose derivatives and of shaped structures therefrom
IPC: C08L1/22
Filed: 1935-10-11
Abstract: Artificial threads and fibres, bands, coatings, dressings, cements, plastic masses, and other shaped structures are made from the product resulting from the bringing-together of a cellulose ether in solution or suspension in caustic alkali, and a product of the reaction of carbon disulphide on alkali cellulose, such latter product not being in solution or in incomplete solution in water or alkali solution. By such method the cellulose xanthate is brought readily into solution, and there is produced even from undepolymerized cellulose, solutions containing a high total percentages of cellulose, say 9--12 or more per cent, which are flowable and easily filterable; the structures resulting from these solutions are of good strength and extensibility; in addition, solutions can be obtained with the use of relatively small proportions of carbon disulphide, for example, less than 30 per cent of the cellulose and cellulose ether, preferably less than 20 per cent, even less than 10 per cent, for example, 3--1 per cent.  The cellulose ether may be soluble in caustic alkali at room temperature or may be brought into solution by cooling as by the process described in Specification 212,864; cellulose esters which are insoluble or only partly soluble under these latter conditions may also be employed.  Solution of the cellulose xanthate in the solution or incomplete solution of the cellulose ether may be effected by cooling to 0 DEG  C. or lower.  The cellulose p  ether may contain less than one, even less than 0,5 substituted or unsubstituted alcohol radicle per C6H10O5 unit, and such radicle may be alkyl, hydroxyalkyl or hydroxy acid, or a mixture of these.  The proportion of cellulose ether to cellulose xanthate may vary within wide limits, for example, from 0,1 : 1 to 29 : 1.  For the working-up of the cellulose ether-cellulose xanthate solution into shaped structures there may be employed baths capable of coagulating viscose, in particular there may be used baths having a plasticizing effect on the coagulated product, for example, baths containing 25--70 per cent sulphuric acid; or the originally coagulated product may be plasticized in a later bath.  In the case of such products as artificial threads, the latter may while in the coagulation bath or during their travel to the collecting device, be subjected to stretching.  There are a number of examples describing the production of suitable cellulose ethers and cellulose xanthates, and the production of the mixed solutions thereof, and the working-up of such solutions into artificial structures.
