Title: Temp. dependent imaging contrast improvement - by feeding radiation detector outputs to differential amplifier providing intensity modulation
Inventor: ZEIFANG GUENTER DR RER NAT
IPC: H04N5/33
Filed: 1976-02-03
Abstract: The contrast improvement method for temperature dependent imaging equipment compares each point of the scanned image with its surroundings to provide a weighted signal which is subtracted from the image element signal. Alternatively, the image signal is divided by the weighted ambient signal. The resulting signal is used to intensity-modulate the display. The method is suitable for single-detector units or for equipment using detector arrays. The target scene is scanned by mirrors (sp1-2) and the radiation is focussed via an object lens (o) onto twin detectors. The detector outputs are fed to a differential amplifier. The amplifier output signal is used to intensity-modulate the electron beam of the monitor. The monitor scan is synchronised with the mirror movement.

Title: Aerator and stirrer for liquid effluent - designed to disperse gas in small bubbles without surging
Inventor: POEPEL FRANZ PROF DR ING
IPC: B01F3/04
Filed: 1976-10-15
Abstract: An aerator for liquid has a rotor under the liquid surface. It is driven and draws air through a submerged tube leading to the surface and liquid from below. The rotor resembles a double sided centrifugal pump in pallor. The housing forms guides on each side of the rotor. The submerged tube opens near the rotor and is surrounded by a screen roughing at right angles to its axis. The screen axially and radially extends as closely as possible to the suction region of the rotor and may be formed by the rotor. Used for aerating and stirring effluent water, sludge, liquid fertiliser and substrates with high contents of organic materials. The aeration promotes physical, chemical or biological reactions e.g. flotation of colloidal material neutralisation of alkali by flue gas, removal of carbon from acid water, oxidation of organic material. The gas is dispersed as fine bubbles which rise only slowly. The working is stable and does not draw in rapidly varying volumes of air.
