Title: Process for separating off and recovering chlorofluorocarbons from mixtures of chlorofluorocarbons and other gases
Inventor: KAMBACH MATHIAS
IPC: B01D5/00
Filed: 1988-12-27
Abstract: To prevent an excessive emission of chlorofluorocarbons in industrial production processes, e.g. in their use as a propellent gas in foamed plastic production or as an insulating gas in the electrical industry, and their simultaneous recovery for reuse, the mixture of chlorofluorocarbon and other gases, e.g. air, is drawn in by suction and compressed. With simultaneous compression and cooling, the chlorofluorocarbon contents are liquefied and thus separated from the remaining mixture. The remaining non-condensable gases are given off to the surroundings via an automatic venting device. The recovered chlorofluorocarbon has a high degree of purity and can be reused. The emission of chlorofluorocarbons hazardous to health and the environment can be reduced to a minimum. The process can be applied to all chlorofluorocarbons, even those having a very low boiling point, since for each of these media the condensation temperatures and condensation pressures associated with it can be established exactly.

Patent DE-3907385-A1 (DE)
Title: Fluid friction clutch
Inventor: GEIST ANSGAR
IPC: F16D35/02
Filed: 1989-03-08
Abstract: The fluid friction clutch has two parts (7b, 21b) which are rotatable relative to one another about a common axis of rotation (1b) and between them bound a zig-zag or meandering shear gap (23b). The shear gap (23b) is bounded by ribs (59, 61) which are coaxial with the axis of rotation (1b) and interlock alternately to form the zig-zag or meandering shear gap (23b). The individual ribs (59, 61) have side flanks (63, 65 and 67, 69, respectively) which are inclined towards one another and the generatrices of which are inclined at mutually differing angles to the axis of rotation (1b). The parts (7b, 21b), which are rotatable relative to one another, of the clutch have a different radial thermal expansion, so that the shear-gap portions (75, 77) defined by the side flanks of the ribs (59, 61) and with a different inclination to the axis of rotation (1b) contract and expand to varying degrees in the event of a change in temperature. The different inclination of the shear-gap portions (75, 77) determines the course of the output speed/input speed characteristic of the fluid friction clutch in the range of the higher input speeds.   <IMAGE>
