IPC: G01T1/24
Filed: 1961-05-09
Abstract: 1,018,402. Measuring radiation intensity. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 18, 1962 [May 9, 1961], No. 16856/61. Heading G1A. [Also in Division H1] A radiation detector consists of a plurality of superimposed PN junction or surface barrier devices which are air-spaced or held apart by insulating spacers, has means for applying a reverse potential bias to each of the junctions or barriers, and has means for detecting radiation-induced discharge through the junctions or barriers. The devices are made and biased to such an extent that the depletion region associated with the junction or barrier reaches as much of the semi-conductor wafer as possible short of breakdown. A voltage pulse proportional to "particle" energy is obtained from the detector provided that the "particle" is absorbed in the device-linearity of response is therefore ensured for high energy "particles" by suitably increasing the number of devices used in the stack. The devices in the stack may be connected in series or in parallel.

Title: A process for the preparation of trichloromethane phosphonic acid monohydrate and anhydrous trichloromethane phosphonic acid; and the resulting monohydrate and anhydrousacid
IPC: C07F9/38
Filed: 1955-06-16
Abstract: Trichloromethane phosphonic acid monohydrate is made by hydrolysing trichloromethane phosphonic dichloride dissolved in an inert water-immiscible organic solvent, e.g. a hydrocarbon or halogenated hydrocarbon boiling below 250 DEG  C., with water.  The reaction is suitably carried out by heating a solution of trichloromethane phosphonic dichloride, in a solvent such as carbon tetrachloride at a temperature between 50 DEG  and 200 DEG  C. in the presence of between 2 and 50 molecular proportions (preferably between 5 and 25 molecular proportions) of water. Anhydrous trichloromethane phosphonic acid is made by distilling the monohydrate with a volatile liquid water-entraining such as a hydrocarbon or halogenated hydrocarbon boiling between 100 DEG  and 210 DEG  C., for example petroleum naphtha or mono-chlorbenzene. Suitably the anhydrous trichloromethane phosphonic acid may be made directly by a combined process wherein trichloromethane phosphonic dichloride is distilled with water and a water-entraining organic solvent to remove water, hydrochloric acid and a part of the organic solvent, leaving an organic phase comprising the remainder of the organic solvent and anhydrous trichloromethane phosphonic acid.  In this process the organic solvent is preferably one that forms a ternary azeotrope with water and hydrochloric acid and the amount of water employed is preferably 4-15 molar proportions of the amount of trichloromethane phosphonic dichloride.
