Abstract: A process for the biological purification of effluent which is contaminated with nitrogen in the form of ammonium, nitrite or nitrate ions or in the form of organic compounds, by oxidizing the nitrogen under aerobic conditions and reducing the nitrogen under anaerobic conditions, wherein the sewage to be treated, mixed with activated sludge, is subjected, in an aeration basin, to oxygen-containing gas bubbles introduced from below and is thereby simultaneously enriched with dissolved oxygen, to oxidize carbon compounds and nitrogen compounds, and transported upward, by the buoyancy of the gas bubbles, releases gas at the surface of the liquid and, due to the higher average density of the mixture of lower gas content, in part automatically again flows downward in the aeration basin, to undergo further aeration, while in part it overflows into a denitrification basin which communicates with the aeration basin through an opening at the liquid surface, and an opening at the bottom of the partition, is mixed, in the denitrification basin, with the contents thereof by mechanical means and flows back, through an opening near the bottom, in the partition, to the aeration basin. The invention further relates to an activated sludge basin, wherein jet aerators are arranged parallel, and horizontally, at the bottom of the basin, a vertical partition divides the basin into an aeration compartment and a denitrification compartment, both compartments possessing jet aerators, and passages in the partition connect the two compartments of the basin in the area of the surface of the liquid, and in the vicinity of the bottom.

Title: Proportional integral controller with improved transient response - has amplifier feedback capacitor switch dependent on error level
Inventor: KUEHNEL WERNER DIPL ING
IPC: G05B5/01
Filed: 1980-06-23
Abstract: A proportional-integral controller contains an operational amplifier (1) whose output signal is fed back to its input via a series resistor-capacitor circuit (9,8). The transient behaviour in response to a control difference is improved. Overshoots are minimised. A switch (10) connected in parallel with the feedback capacitor (9) is controlled from the output of a comparator (12) whose inputs are connected to the actual and demanded values of the control parameter (X). The feedback capacitor is shorted out by the switch as long as the control difference (w-x) exceeds a defined value. In this state the circuit acts a purely proportional controller. The capacitor is switched in shortly before the actual value reaches the demanded value so as to prevent overshoot.

Title: Magneto-optic storage medium
Inventor: OHTA KENJI
IPC: H01F10/13
Filed: 1981-02-23
Abstract: A novel magneto-optic storage medium is described which has a layer consisting of amorphous magnetic material, typically a GdDyFe layer, whose Curie point or Curie temperature is below the crystallisation point or crystallisation temperature of the material (for example 120 DEG C compared to 350 DEG C), so that it becomes possible to accomplish, via the crystallisation of the amorphous magnetic material, changes in the optical properties such as the transparency or the reflectivity, so that it is thus possible to store data by writing thermomagnetically. In so doing, reversible recordings are stored by thermomagnetic writing, for example by Curie point-writing on the layer consisting of the amorphous material, while read-only or permanent recordings are recorded on the layer consisting of the amorphous material by causing crystallisation of the layer consisting of the amorphous material with the aid of a laser beam.
