Title: Improvements in or relating to short wave thermionic valve circuit arrangements
IPC: H03F1/16
Filed: 1937-04-26
Abstract: 490,258. Valve amplifying circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. April 26, 1937, No. 11947. Convention date, April 24, 1936. [Class 40 (v)] In short-wave amplifiers operating in known capacity neutralized circuits, it is found that owing to the anode-cathode and anode-grid capacities being of the same order, the grid has an apparent low input resistance. This difficulty is overcome by dividing the anode circuit inductance into two portions, effectively in parallel as regards high frequency with gridanode and neutralizing capacities. The anode inductance is divided into two parallel portions I, II, the branch I being connected at the point M by a blocking condenser CB, which may be adjustable, to the grid G. The junction of the capacity voltage-divider CSP, CSP is earthed with the cathode K. The upper portion of coil I is in parallel (as regards high frequency) with the grid-anode capacity CAG and the lower portion is in parallel with the neutralizing condenser CN, and if the portions of the inductance are in the same ratio as their parallel capacities the grid shunting effect is reduced. The two portions of the inductance may be arranged to form a tuning variometer.

Title: Improvements in and relating to the manufacture of material from difficultly-tractable animal fibres
IPC: D06M15/05
Filed: 1930-04-15
Abstract: Yarns or fabrics made from difficulty tractable animal fibres, e.g. mohair, goat-hair, horse-hair, and lower grades of wool, camel and alpaca, blended or otherwise, in combination in the state of yarn or fabric with vegetable fibres, e.g. cotton, flax, hemp, ramie, and jute, are impregnated with a solution of cellulose or of a cellulose ester which is capable of withstanding the heat ordinarily applied in tailoring operations, is resistant to the solvents ordinarily used for cleaning purposes, and is less inflammable than nitrocellulose. Cuprammonium or zinc chloride solutions of cellulose, alkaline solutions of cellulose hydrate, and solutions of cellulose acetate or formate or of viscose are suitable impregnants.  The impregnating solution preferably includes a plasticiser, e.g. triacetin, triphenyl or tricresyl phosphate, or diethyl or diamyl phthalate, in the case of cellulose acetate.  A specified solution contains alcohol 20, benzol 24, acetone 45, cellulose acetate 5, triacetin 5,2, and triphenyl phosphate 0,8 per cent.  The solution may be applied by spreading, spraying, brushing or flowing-on, or by immersing the material in the solution, and when treating fabrics the solution may be applied one or more times to one or both sides. The treatment reduces the tendency of the animal fibres to become displaced, and may be applied to the manufacture of padding and stiffening material for clothing.

Title: Fluorination of halogenated organic compounds
Inventor: BENNETT ROYSTON HENRY
IPC: C07C17/20
Filed: 1964-03-20
Abstract: Fluorine compounds are obtained when an aromatic compound containing carbon and halogen only (at least one of the halogens being other than fluorine) is passed in a series of incremental portions in the vapour phase into a reaction vessel packed with a dry sub-divided alkali-metal fluoride, the amount of fluoride initially available for the treatment of the first increment being 20-100 times the weight of that required for the complete fluorination of the first increment of the aromatic compound and the process being effected at 500-650 DEG C. under a pressure of 0.5-5 atm.  The process may be carried out by passing successive portions of vaporized organic compound into the alkali-metal fluoride, each portion being allowed to react before the next portion is passed in. Alternatively, a continuous stream of the vaporized organic compound may be passed through the alkali-metal fluoride.  A reaction vessel of nickel-chromium or aluminium is preferred, but reference is made also to the use of iron, copper and "Monel" metal.  Examples are given in which mixed products containing hexafluorobenzene, pentafluorochlorobenzene, tetrafluorodichlorobenzene, trifluorotrichlorobenzene, difluorotetrachlorobenzene and a little decafluorobiphenyl are produced by treating hexachlorobenzene with potassium fluoride at 560 DEG  C.
