IPC: C02F3/26
Filed: 1992-02-19
Granted: 1993-07-15
Abstract: Removing nitrogen- and carbon cpds. from waste water comprises mixing waste water in a first aerobic stage with active sludge and incorporating O2 in a limiting amt. so that besides partial oxidn. of the organic coponents present in the waste water, adsorption of these onto the active sludge occurs in controllable amts. The mixt. is then subjected to an intermediate clarification in which the clear phase of the resulting suspension is sepd. from active sludge. The sepd. clear phase is subjected to a nitrification stage in anoxic medium by contact with further active sludge, and the nitrified waste water is subjected to a denitrification stage in anaerobic medium together with the active sludge sepd. in the intermediate clarification state. USE/ADVANTAGE - The controlled oxidn. of organic substances in the first aerobic stage causes a certain amt. of these to be adsorbed onto the active sludge which is then sepd. in the first intermediate clarification stage and used in the anoxic denitification stage, where the adsorbed organic cpds. act as C source to allow complete elimination of the nitrogen cpds. High rates of reaction are achieved so that highly loaded reactors can be operated at high efficiency to give excellent removal of contaminants from waste water and without formation of odours.

Title: Method detecting cause of reset in microprocessor controlled system
Inventor: DUBA PETER
IPC: G06F1/24
Filed: 1994-03-18
Granted: 1995-08-10
Abstract: The method involves recognising from the voltage at the microprocessor port immediately after reset if it is a short or long reset. A reset operation is caused either by switch-on of an external supply voltage (long-reset) or by short term fluctuations of the supply voltage and also by failure states (short-reset). A capacitor (16) is charged when an external supply voltage is present. The capacitor discharges with a predetermined discharge time constant, which is longer than the short reset, when there is a faulty external supply voltage. The capacitor is connected to a port (12) of the microprocessor which is connected as an input port directly after a reset so that the microprocessor can direct from the presence of a voltage on the port after a reset state whether the reset is short or long.
