  • Patent number: 5750949
    Abstract: A metal-encapsulated, gas-insulated high-voltage circuit-breaker includes a fixed contact configuration which is accommodated in its own fixed contact housing, and a moving contact piece configuration which is driven by a first drive and is accommodated in a contact housing that is connected to the moving contact piece configuration or can move with said contact piece configuration during a switching operation. The contact configurations may have contact pieces for a rated current and for guiding and extinguishing an arc. At the same time, a device is provided for producing a gas flow. The device includes a dielectric nozzle in which the arc burns and is blown and which is guided in a sealed manner in the fixed contact housing throughout an entire switching operation.

  • Patent number: 4251924
    Abstract: The drying medium (T) is driven through the adsorbent (5) of the adsorption cell (1) in the same direction as the process medium (P). Initially it is ejected through an auxiliary output (19) and a device (26) for removal of dampness and then is changed-over towards a main output (18) and preferably into the workroom (A).

  • Patent number: 4021211
    Abstract: A process and apparatus for separation of solvents from an air stream laden with solvent vapors by adsorption using active carbon followed by regeneration of the carbon by desorption by steam using a plurality of active carbon chambers. The sequence of charging and regeneration of the active carbon is controlled automatically in dependence upon the concentration of solvent vapors in the air stream. During the change over from charging to regeneration the active carbon is first subjected to desorption by steaming with a large volume of steam and then, when steam breaks through on the outlet side of the carbon the volume of steam is reduced for the purpose of drying the carbon. The change over is effected by a measuring device arranged on the outlet side of the carbon chamber responsive to a pre-determined threshold concentration of solvent vapors in the outgoing stream.
