Abstract: A module (1) for a detector (14) of ionizing radiation comprising at least two detection segments (2) for detecting ionizing radiation, attached to a row carrier (3) allowing for the assembly of detectors (14) with an unlimitedly large detection surface for continuous imaging of ionizing radiation. The construction of the module (1), including a means (10) for power supply stabilization for each detection segment (2), an interconnection of electrical conductors (8), formed by printed circuit boards (9, 13) led vertically downwards perpendicular to the detector surface along the row carrier (3), and a parallel connection to the connectors (11) of the read-out electronics, increases the reliability and speed of the operation of the detector (14). Between the individual parts of the module (1) there are formed thermal bridges to stabilize the temperature and to increase the reliability of the detector (14) assemblies from the modules (1).

Abstract: A process is described for the production of alcoholates from alkali metal hydroxides and aliphatic alcohol which in their molecule contain 1 to 6 carbon atoms. The alcoholates are produced in that alkali metal hydroxide is mixed with an alcohol and is reacted with said alcohol at a temperature from 80.degree. to 110.degree. C., preferably from 80.degree. to 100.degree. C., and under a pressure from 0.3 to 1.2 bars, the alcohol water mixture which evaporates during the reaction is separated into its components by at least one membrane, the alcohol vapor and the water vapor are condensed and the condensed alcohol is recycled to the reaction.
