Abstract: As in the case of the irradiation of plane materials, the production of an inert atmosphere for the radiation-curable coating plays a decisive role with regard to the operating costs and the quality of the resulting product in the case of the curing of shaped parts. The present invention shows that the production of an inert atmosphere with the aid of a vacuum/inert gas lock with subsequent feeding through the lock into a radiation chamber constitutes an inexpensive means of producing an inert atmosphere for shaped parts, since flushing of the radiation chamber 8 to 10 times before each irradiation operation, as was necessary in the past, is dispensed with.

Abstract: A process for the incremental enrichment of deuterium and/or tritium in a material which is suitable for the isotope exchange of deuterium and tritium with hydrogen, and an arrangement for the implementation of the process. The process and arrangement for the enrichment of deuterium and/or tritium in water which, in addition to a high transport speed for the molecules which participate in the isotope exchange, evidences a high enrichment factor for each enrichment stage and a high yield, so that at a relatively small number of stages and low energy consumption there is attainable an overall high degree of enrichment. For each enrichment stage, water containing deuterium and/or tritium is introduced into a carrier gas flow, reduced and set to a hydrogen (H2) partial pressure of maximally 100 mbar. Subsequent thereto, the carrier gas flow is conveyed along the primary side of an exchange wall which is suitable for the permeation of hydrogen, along the secondary side of which there flow a further carrier gas flow which contains a material adapted for the isotope exchange of deuterium and tritium with hydrogen in the gas phase thereof. The hydrogen isotopes deuterium and/or tritium which permeate through the exchange wall, after the isotope exchange, are bonded with the material in reaction product.

Abstract: @ A DC-to-AC voltage converter for the supply of power to at least one load, comprising an input circuit and at least one output circuit galvanically separated from said input circuit, and a converter transformer. According to the invention a primary winding of the converter transformer is series-connected to a switching transistor, which series circuit arrangement is connected between a positive input terminal and a negative input terminal, with one or more resonance capacitors being connected in parallel with the collector-emitter circuit of the switching transistor and/or in parallel with said primary winding. Control means are provided for said switching transistor, with the resonance capacitor(s) and said primary winding being dimensioned so that, under all anticipated load conditions of the converter, including short-circuiting of the output circuits, the control means cause the voltage across the collector-emitter circuit of the switching transistor, after the latter has become non-conductive, to fall back to a very low value before the switching transistor is again driven into the conductive state. The converter transformer has a first auxiliary winding strongly coupled with said primary winding and, at least in part, provides the driving power required for the switching transistor. A time-delay and turn-off circuit is energized and synchronized by at least one second auxiliary winding of the converter transformer, and a smoothing circuit provides the driving power for turning off the switching transistor, which driving power is withdrawn from a third auxiliary winding of the converter transformer.
