Title: Maintaining sewage tank - has circulation produced by lifting worm producing internal drawing pressure difference
IPC: B01F5/10
Filed: 1989-10-17
Granted: 1991-04-11
Abstract: Liq. laterally fed into a distributor adjacent the wall of an unpressurised container and circulating in the body of liq. enters a cranked rising conduit whose upper section includes a rotating worm. It then lifts liq. towards discharge into the distributor. The upward worm force creates a lower liq. level in the approach to the worm, which in conjunction with the higher level at the distributor causes a pressurising head to cause circulation, with avoidance of dead zones. Reqd. gases, flocculants etc. are introduced at a constriction in the ascending conduit. USE/ADVANTAGE - For circulating sewage contg. reactive  bacteria. Gentle circulation ensures no mechanical damage to bacteria.

Patent DE-4234393-C1 (DE)
IPC: F01K23/06
Filed: 1992-10-07
Granted: 1993-09-16
Abstract: A process for compressing a gaseous medium, particularly air, in which sucked in gas of a lower initial pressure, particularly atmospheric pressure, is compressed to a predetermined final pressure by means of a compressor driven by the useful side of a thermal engine. The sucked in gas is pre-compressed before entering the compressor and/or the compressed gas is re-compressed after exiting the compressor by a turbocharger. The drive side of the turbocharger is acted upon by the energy of the exhaust gas flow of the thermal engine. In order to increase the overall efficiency of transportable compressor installations in particular, a liquid of a closed or open liquid/steam circulation system, which liquid is under pressure, is evaporated and superheated by the exhaust gas flow of the thermal engine and the superheated steam is fed to the drive side of the turbocharger.
