Patent DE-3560091-D1 (DE)
Title: The use of hydrophilic, highly filled polyurethanes in biological waste water purification
Inventor: REISCHL ARTUR DR
IPC: C02F3/06
Filed: 1985-01-14
Granted: 1987-04-23
Abstract: The present invention relates to the use of non-floating, non-abrasive, highly-filled polyurethane (urea) compositions of high water-absorbability, which during their production contain no cells capable of growth as carriers for biomasses in the biological treatment of waste-containing liquids. These carriers have a filler content of greater than 15% by weight and less than 95% by weight (based on the moisture-free weight of the filler-containing polyurethanes). The fillers are selected from the group consisting of natural materials containing finely-divided fossil lignocelluloses or the secondary products thereof (e.g., peat, lignite, mineral coal or coke), active carbon, finely-divided distillation residues, inorganic fillers, homogeneous or cellular plastics particles (and more particularly polyurethane foam (waste) particles) and mixtures thereof. The polyurethane (urea) is a hydrophilic and/or hydrophobic polyurethane(urea), and preferably contains cationic groups. These highly-filled, polyurethane (urea) carriers have a water-absorbability exceeding 33% by weight of water in the swollen carrier. These carriers allow improved treatment of industrial and municipal liquid waste to be achieved in biologically-operating treatment plants. Treated waste which has reduced toxicity, a diminished smell, improved clarity and a very small residual content of organic, decomposable material is obtained due to the increased decomposition effect thereof.

Patent DE-3650669-D1 (DE)
Inventor: KRAUSE JAMES N
IPC: G11B5/55
Filed: 1986-11-19
Granted: 1998-05-07
Abstract: A thermal test track (- 3) is provided outside the user-accessible area on the disc. A track complete of a known frequency is then written on either side of this thermal test track, preferably half the usual track separate distance away. To develop a thermal compensation constant, the transducer (10) is moved to the thermal test track with no compensation applied. This way, any thermally induced off-track error, which would affect seeks to user-accessible data tracks, will be reflected in the off-track from the nominal position of the thermal test track. The transducer is now moved in a series of defined increments (e.g. 5) smaller than normal track-to-track steps, or "micro-steps", away from the uncompensated position of the thermal track toward one of the tracks written with the known frequency. When the data on the written track to the side of the thermal test track is detected, a note is made of the number of micro-steps the transducer has been moved. The transducer (10) is then micro-stepped incrementally in the opposite direction until the data written on the other side of the thermal test track is detected. A simple comparison of these two micro-step counts will yield the existing thermal shift, which can be converted into a thermal compensation constant for the transducer positioning mechanism by means of a simple look-up table.

Granted: 1991-12-12
Abstract: The sensitivity-calibration circuit for absorption analyzers comprises two separate temperature-compensation circuits (A, B), one (A) for compensating the temperature-drift resulting from the optical system of the analyzer and the other one (B) for compensating the temperature-drift caused by a sample system of the analyzer. The latter mentioned temperature-compensation circuit (B) can be blocked-off from operating on a checking and/or measuring input signal (VIN) by use of a switch (SW) such that during a measuring state both temperature-compensation circuits (A, B) are cooperating in sequence whereas during a specific checking state by switching over switch (SW) only said temperature-compensation circuit used in connection with checking the optical system is actively operating on said input signal (VIN). The advantage over the prior art combination sensitivity-calibration circuits is a more accurate and reliable calibration of the absorption analyzer during both, the measuring state and the checking state of the whole system.
