Abstract: An ionization device includes: a plasma generating device for generating metastable particles and/or ions of an ionization gas in a primary plasma region; a field generating device for generating a glow discharge in a secondary plasma region; an inlet for supplying a gas to be ionized into the secondary plasma region; and a further inlet for supplying the metastable particles and/or the ions of the ionization gas into the secondary plasma region. A mass spectrometer includes such an ionization device and a detector downstream of the outlet of the ionization device for the mass-spectrometric analysis of the ionized gas.

Abstract: Silicone elastomers exhibiting high breakdown voltage and improved static decay characteristics are prepared from a crosslinkable silicone composition containing an ethylenically unsaturated polyoxyalkylene polyether which becomes chemically bonded into the elastomer during cure.

Abstract: Composite insulators having a silicone rubber shield are economically produced by coating at least a portion of a support with a crosslinkable silicone rubber composition containing a light activated hydrosilation catalyst, and irradiating the crosslinkable silicone rubber composition to activate a crosslinking reaction.

Abstract: In separating hydrogen from a mixture of gases by diffusion through a non-porous membrane which is selectively permeable to hydrogen, the hydrogen being at least partially dissociated prior to being contacted with the membrane, the membrane is made up of at least two layers of different materials. The layer on the upstream side of the membrane is less dissolving to hydrogen and has a lower release rate constant at 300.degree. C. than the layer on the downstream side. The membrane may consist of an iron diaphragm with a thin coating of copper on the upstream side.
