Abstract: The invention relates to a method of separating from a gaseous medium vaporous substances having a low boiling point contained in high proportions in the medium, by subjecting said medium to a scrubber where said vaporous substances are precipitated as cold liquid condensates the coldness component of which is transferred to a circulating refrigerant. Provisions are made for different levels of coldness by utilizing cold-vapor and cold-air refrigeration units in which condensates and clean air produced by the system are used as refrigerants. Heat generated by a compressor in the cold-air refrigeration unit may additionally be used in a degassing unit used to remove non-condensible components from the condensate and/or refrigerant.

To the conveyor device, a device for transferring sets of plates (9) is assigned that can be moved in the vertical direction between, in relation to the conveyor device, a raised position and a lowered transfer position. While in the raised position, the transfer device (9) can be charged alternately and cyclically from magazines (2, 6) located opposite one another in pairs with a negative plate, a separator plate, a positive plate and a separator plate, the transfer device (9) being capable of being lowered stepwise in accordance with the height of a set of plates. While in the lowered transfer position, the transfer device transfers to the intermittently movable conveyor device, the stack of plates formed on said transfer device from a predetermined number of sets of plates.

Abstract: A sheet feeding method and apparatus particularly suited to handling plastic sheets having a tendency to adhere to each other under electrostatic action, in which the uppermost sheet of a stack is fed by first lifting the rear edge of the sheet into a generally arcuate configuration and translating a lifting member forwardly under the lifted rear edge to progressively separate the uppermost sheet from the rest of the stack. The lifting members preferably in the form of an idler roller which translates to a position in cooperation with a drive roller so that the sheet becomes sandwiched between the tow rollers for final feeding from the stack. The mechanism features a pick assembly particularly suited for engaging and lifting the rear edge of each sheet into a predictable arcuate configuration.
