Abstract: A device for imaging the local distribution of at least one thermodynamic variable includes a radiation emitter capable of emitting electromagnetic radiation and a filter for filtering electromagnetic radiation. The emitter and the filter form an arrangement adapted for modifying the electromagnetic radiation emitted by the emitter in dependency of the local distribution of at least one thermodynamic variable at the location of the arrangement. The emitter further includes at least one electroluminescent layer and the filter is provided with at least one filter layer. The electroluminescent layer and the filter layer are integrated within a cohesive sequence of layers. The device is particularly suitable for infrared camera systems.

Abstract: A process and use of at least one catalyst for phosphorylation, in particular phosphitylation, of hydroxyl groups, whereby a phosphorous compound is added to a hydroxyfunctional compound having at least one hydroxyl group. The addition yields a phosphorylated product having at least one O—P bond. The catalyst employed in the process is of the general formula (R1)nX(R2)4−n, wherein each R1 independently is hydrogen, at least one hydrocarbyl, amino, halogenated and/or silylated hydrocarbyl group, X is Si, Ge or Sn, each R2 independently is a leavening group and is F, Cl, Br, I or a sulphonate group optionally being halogen substituted and wherein n is 1, 2 or 3.

Abstract: A compound of the formula ##STR1## in which R.sup.1 and R.sup.2 each independently is an optionally substituted alkyl, aralkyl, aryl, alkoxy, aryloxy, aralkoxy, alkylthio, arylthio, aralkylthio, alkylamino, arylamino or aralkylamino radical,is produced by reacting a compound of the formula ##STR2## in which X is hydrogen, an alkali metal ion, an optionally alkyl- ,aralkyl- and/or aryl-substituted ammonium radical, a trialkylsilyl radical, or ##STR3## with bromine in the presence of an inert diluent at a temperature from about -50.degree. to 20.degree. C.The product can be employed as a flame retardant, a vulcanizing accelerator and/or an intermediate for synthesizing pesticides.
