[Class 40 (iii).] Copper-oxide cells are made from easily separable portions 2 of a plate 1 which is slotted as shown at 3 and hung by a hole 5 in an electric furnace at 1000‹ C. for 24 hours and then at 520‹ C. for 2 hours and finally cooled in still air. The discs 2 having been completely oxidized, boiling citric acid is applied to them for the purpose of removing the cupric oxide and deoxidizing the outer surface of the layer of cuprous oxide. The layer of reduced copper so formed is then washed off and the plate is immersed in a saturated solution of silver cyanide for smoothing the surface and neutralizing residual acid. Graphite and a thick coating of gold are next applied, and finally a photo-electric contact layer of gold is sputtered on to the surface. Suitable dimensions and conditions are detailed in the Specification. The element is finally coated with shellac or celluloid. Fig. 2 (not shown) shows how to cut the plate 1 when rectangular portions 2 are required.

IPC: C08G63/668
Filed: 1954-08-20
Abstract: An alkyd resin, compatible with vinyl resins, is made by reacting (1) 2,4-dimethyl-4-hydroxyethoxymethyl - 1,5 - pentanediol ("triol A"); (2) a dicarboxylic acid or anhydride, e.g. phthalic, tetrahydrophthalic, maleic, succinic, adipic, glutaric, pimelic, sebacic, terephthalic or 1,4 - endomethylenetetrahydrophthalic; and (3) a monocarboxylic acid containing at least eight carbon atoms, e.g. 2-ethylhexoic, caprylic, capric, myristic, palmitic, stearic, lauric, oleic, linoleic, linolenic, ricinoleic, elaeostearic, or abietic; or soya, cottonseed or tung oil fatty acids.  Preferably the alkyd has an acid number of 2-20 and the mol. ratio of dicarboxylic acid to monocarboxylic acid is 5.1-0.8 : 1.

In a further example (8) maleic anhydride was heated with rosin at 200 DEG  C. for 1/2 hour, triol A was added and the mixture heated to 250-260 DEG  C. for 9 hours to produce an alkyd of acid number 48. Coating compositions were prepared by combining these alkyds with the following vinyl resins in the weight ratio 4 : 1, 1 : 1 and 1 : 4 (a) polyvinyl chloride, (b) a copolymer of vinyl chloride 87 per cent, and vinyl acetate, 13 per cent, (c) a copolymer of vinyl chloride 95 per cent, and vinyl acetate, 5 per cent (d) a copolymer of vinyl chloride 94 per cent, and vinylidene chloride, 6 per cent.

Abstract: 902,484. Discharge apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 29, 1960 [July 15, 1959], No. 24348/59. Class 39 (1). In a discharge device, the electrode structure supports a capsule which contains granular material capable of emitting a vapour. The cap sule has a porous wall permitting escape of the vapour but not of the granular material. As shown, the nickel capsule 15 has a cupshaped portion and a coverplate having a central porous region formed by compressing a mixture of nickel powder and paraffin wax into the centre of an annular nickel plate and heating. The capsule, which may alternatively be of molybdenum or tungsten, contains a mixture of caesium chromate and silicon powder, which, upon induction heating, gives off caesium vapour to sensitize the antimony coatings on the dynodes 7-9, 11 and 12. The electrode structure further includes a photoemissive cathode 6 and an anode 13. In a further embodiment of the invention, a " Trigatron " (Registered Trade Mark) is provided with a capsule containing a mixture of potassium chlorate and manganese dioxide to provide a continuous supply of oxygen during operation

Abstract: 644,553. Keyboard switches. STANDARD TELEPHONES & CABLES, Ltd. Sept. 17, 1948, No. 24412. Convention date, Nov. 14, 1947. [Class 38(v)] A selector switch comprises rows of vertical wires 3 arranged side-by-side and behind each other, each wire co-operating with horizontal insulating or conducting wires 2, carrying spring contacts 4, 5, at the crossing points. The springs are wound round the wires 2 and adjacent springs in a horizontal row are connected together by continuations of the springs themselves. The natural tension of the springs urges them towards the vertical wires, but they are normally held out of engagement therewith by insulating spring plungers 7 having cut-outs 10 engaging the springs 5. On selective depression cf a plunger, the associated springs 4, 5 are released so as to engage the adjacent wires 3. The latter may be connected in parallel in pairs as shown, or there may be one or more wires per spring and associated with separate circuits.

Title: Improvements in or relating to graphite
Inventor: LONGSTAFF BRIAN
IPC: C01B31/00
Filed: 1965-06-09
Abstract: A graphite artefact has about 50% of its open pores of size 5-10 m with substantially the remaining 50% less than 0.1 m , there being few pores of size 0.1-5 m .  The artefact may have a viscous permeability constant below 3 x 10-11 cm.2 and a fission gas transmission coefficient below 10-6 cm.2/sec.  The artefact is produced from a graphite grist whereof substantially all the particles are larger than 50 m . The grist is mixed with a binder, and the green mixture worked into a green artefact which is carbonized, impregnated with pitch, recarbonized and graphitized. The impregnating and baking steps may be repeated prior to graphitizing.  The carbonizing steps may be carried out under pneumatic pressure.  The preferred binder is a coal-tar pitch having a softening point of 90 DEG  C., and may be present to the extent of 27-30 wt. per cent in the green mix. Preferred graphite starting grists have compositions by weight of 0-2% above 422 m , 43-48% between 422 and 251 m , 27-28% between 251 and 124 m , 15-17% between 124 and 70 m , 5-7% between 70 and 53 m , 0-7% below 53 m .
Patent GB-624008-A (GB)
Title: Improvements relating to the production of solutions of organic bases
IPC: B01J39/00
Filed: 1946-08-16
Abstract: Solutions of organic bases are concentrated by adsorbing the base from a relatively dilute solution on to a number of beds of hydrogen ion exchange material and passing a single solution of a displacing base through each bed to displace most of the organic base from it. Preferably the concentration of the displacing base which is suitably an inorganic base such as caustic soda is less than is required to displace all the organic base from all the beds and the concentration is brought up to the initial value by adding a further quantity of displacing base to the effluent liquid from each bed.  The excess of displacing base in the final solution may be removed by passing through a further bed of exchange material without the addition of more displacing base. The beds may be freed from remaining organic base by elution with a fresh quantity of solution of the displacing base which solution may then be used as the displacing liquid for the treatment of another series of beds.  Beds from which the organic base has been removed may be regenerated by treatment with acid and re-saturated with the organic base.  The process may also be carried out in non-aqueous media, e.g. alcohol.  In an example, a dilute solution of nicotine is adsorbed and eluted with caustic soda solution according to the preferred process.  Alkaloids which are insoluble in water may be concentrated according to this process in non-aqueous solvents, e.g. alcohol.

Void [Abridged as open to inspection under Sect. 91 of the Acts, June 22, 1933]. [Class 7 (iii).] Fuels such as kerosene are gasified and delivered in that condition, under control, to an air intake pipe. Fuel from a tank 1, Fig. 1, is forced by a pump 2 to a release valve 4 and thence to a pipe 3 and coil 5, Fig. 6, within a chamber 6, Fig. 6, to which exhaust gases are admitted, the fuel pipe 3 passing through the exhaust outlet. Coil 5 delivers into a tube 9 by a valve-controlled passage whence the gas passes up tube 12 and is controlled by a valve 13 connected by a rod 17 and arm 18 to a flap 15 in the air inlet passage. The valve 13 is retained seated normally by a spring 19, and the flap 15 by a spring 20, the tension of the latter being adjustable by screw 23, spring 24 and pivoted member 25. The valve controlling the passage into tube 9 is spring loaded, appears to be actuated by rotating a cam-faced sleeve and is described with reference to Fig. 4 (not shown). A spring-loaded flap valve 21, Fig. 6, and the usual throttle valve 16 are provided. Starting may be effected by a lighter fuel by providing a petrol tank the flow from which to a valve 49, Fig. 6, is controlled by a valve connected to an arm on the valve for controlling the flow of the gasified fuel to the tube 9.
