Title: Device for removing condensable components from gases
Inventor: RISTO HANS-JOACHIM
IPC: F25J3/08
Filed: 1986-07-02
Abstract: In order to separate out condensable components, for example water or solvents, from gases, the gases are conducted through heat exchangers, which are acted upon by a coolant. The components condense and freeze in the heat exchanger. The heat exchanger then freezes up more and more and must finally be thawed out. Two alternatingly operated identical installation blocks are consequently required for continuous operation. In order to manage with only one installation block, the heat exchanger is designed as a cooling plate (1). The cooling plate is assigned a radial ventilator wheel (3) with guide vanes open towards the cooling plate in such a way that the edges (4) of the guide vanes scrape over the cooling plate while forming a gap (5). The radial ventilator wheel serves to supply the gas. The frozen condensate is thereby scraped off continuously by the edges of the guide vanes. <IMAGE>

Patent DE-3718425-A1 (DE)
Title: Pump
Inventor: GSCHWENDER ALOIS
IPC: F04D13/08
Filed: 1987-06-02
Abstract: In drum pumps, the intake is formed by the cross-sectional area of a narrowed end of an external pipe, in which a non-return valve is provided. The pump's capacity is reduced by the valve. In the new pump, the reduction in pressure and output caused by the reduced cross-section of the intake is intended to be compensated for, at least approximately. In order to increase the pumping output and compensate for pressure losses, a supplementary intake is provided, which is open when vessels are being pumped out. While the vessel is being pumped out, the liquid is sucked in through the intake and through the supplementary intake, as well. Once the liquid level in the vessel has sunk to the level of the supplementary intake, it is closed, so that no air is taken in through the supplementary intake. The liquid is then sucked in through the intake. The pump ensures a high output, although the intake that can be closed with the non-return valve has only a small cross-section.
