Title: Process for removing nitrogen from sewage and/or waste water and plant for carrying out the same
Inventor: MAIXNER JIRI ING CSC
IPC: C02F3/12
Filed: 1987-11-16
Abstract: The invention solves the problem of waste water treatment by the nitrification - denitrification method and, at the same time, the design of apparatus for removing nitrogen from waste water. The method according to the invention can also be applied in existing water treatment plants. According to the invention, mechanically purified water is enriched with the settled biomass of activated sludge, a re-circulated activation mixture and its light phase after its centrifuging, and the mixture is then denitrified at the same time as thickening the activated sludge.  2 to 5 % of the volume of the thickened activated sludge is machine-dewatered, and the remaining 9 to 5% by volume is then saturated with oxygen together with denitrified water. Then, the ammoniac substances are subjected to bacterial nitrification for 10 minutes to 10 hours at a temperature of 5 to 40 degrees C, and after sedimentation of the flocculated sludge, the biologically purified water is separated. The principle of the equipment consists of dividing the denitrification reactor (1) into a mixing denitrification section (2), a flocculation section (12), and a thickening section (3), and the denitrification reactor (1) is connected by denitrified water piping (7) to the oxidation reactor (8), divided into a carbonisation section (9) and a nitrification section (17), which is connected to the sedimentation tank (22).<IMAGE>

Title: Dynamic error tester of digital/analog converters
Inventor: LINUS MICHAELI
IPC: H03M1/10
Filed: 2009-02-23
Abstract: Dynamic error tester for digital-to-analog converters (1) uses a comparison of sawtooth voltage generated by the tested digital-to-analogue converter (1) with a DC voltage generated by the reference digital-to-analog converter (3) and measured by the digital multimeter (4). This comparison is carried out by the voltage comparator (2). The pulse width at the output of the voltage comparator (2) is evaluated as the ratio of the number of pulses which release the gate (5) controlled by the output of the voltage comparator (2) to the pulse counter (6) to the total number of pulses generated by the control computer (7). This ratio determines the non-linearity over the tested digital-to- analog converter (1). The main contribution is replacement of the necessary precision measurement of the output voltage of the tested digital-to-analogue converter (1) by measuring the time intervals, counting the number of pulses. The accuracy of the tester of the digital-to-analogue converters is determined by the precision of the digital multimeter (4) as a basic measuring device, without the necessity of accurate dynamic voltage recorder. Tester accuracy can be improved by increasing the number of pulses used to calculate the non-linearity.
