Abstract: A scrubbing apparatus for separating gaseous or particulate contents, especially from flue gas, using a plurality of spin spray nozzles arranged such that adjacent spray nozzles have a different spin. Double spin spray nozzles can be used that produce oppositely aimed spray jets of different spin.

Abstract: Upholstery for a seat, rest or couch. The upholstery includes internal channels through which draining air may flow. Valve means that open under load or compression control air flow through the channels. The flow of draining air is increased automatically or given a desired flow distribution by the surface area pressure controlled by a seated person. The cross sections of the valve means and the channels may be designed so that even a very small pressure difference and correspondingly little energy expenditure will provide a satisfactory air flow rate.

Abstract: In a liquid separator for separating liquid components entrained in a two-phase flow, in which the flow is passed through a channel provided with trap pockets for trapping the liquid components and the trap pockets have guide plates upstream thereof the ends of which have separating edges for introducing the liquid into the trap pockets, provision is made for increasing the separating capacity and for reducing the pressure losses by having each separating edge of the respective guide plate disposed at a distance (b) upstream of the associated trap pocket and by making the end of the guide plate curve in the direction leading into the trap pocket.
