Patent SE-511166-C2 (SE)
Inventor: HANSEN BENGT
IPC: C02F3/12
Filed: 1997-03-14
Abstract: A method for treating sludge from wastewater purification is described. In the method, a sludge is treated, which contains phosphorus and at least one metal which originates from precipitation chemicals and which is selected among divalent iron and aluminum, the pH of the sludge being adjusted to below 4, preferably below 2, for dissolving the content of the phosphorus and said metal in the sludge; the remaining sludge is separated; the solution relieved of sludge and containing phosphorus and said metal is treated for precipitation of the phosphorus content of the solution as FePO4 at a pH of 2-3; and precipitated FePO4 is separated. The method is characterized in that the solution which remains after separation of FePO4 and which contains said metal from the precipitation chemicals, is recycled to the wastewater purification. The phosphorus content of the solution is precipitated as FePO4 by adding an at least equivalent amount of Fe3-.

Abstract: A protective helmet (1) has an outer shell (2) and an inner shell (3), the outer shell being displaceable relative to the inner shell by means of at least one sliding layer (4) arranged between the outer shell and the inner shell. In the edge region of the helmet, the outer shell and the inner shell are interconnected, by means of connecting members (5), for absorbing energy on displacement of the outer shell on the inner shell. In this way, impact energy from an oblique impact against the helmet can be absorbed during displacement between the outer shell and the inner shell.

Abstract: FIELD: geophysical borehole measurements, specifically, determination of spatial position of axis of cased boreholes. SUBSTANCE: pickups measuring clearances between body of down-hole logging instrument and wall of borehole are mounted on head and lug of down-hole logging instrument to reduce errors of measurement of zenith angle and azimuth of plane of inclination of borehole caused by angular motions of down-hole logging instrument with reference to borehole walls. Spatial angle of deviation of longitudinal axis of down-hole logging instrument from direction parallel to axis of borehole is computed with use of information from above- mentioned pickups. Then projections of apsidal angle on plane of inclination of borehole and on horizontal plane are found with use of values of present value of apsidal angle, angle of installation of pickups measuring values of clearances between walls of down-hole logging instrument and borehole. Actual values of parameters of borehole are determined by algebraic subtraction of vertical projection from zenith angle and of horizontal projection from azimuth of inclination of down-hole logging instrument. Down-hole logging instrument of inclinometer has pickups of azimuth, zenith and apsidal angles, information transmitting unit, modules of distance pickups mounted in head and lug. Diametrically positioned groups of distance pickups, differentially coupled with use of adders determine values and signs of deviation of centers of sections of head and lug from axis of borehole. Values of angles of positioning of modules of pickups - angles between sensitivity axes of specified pickups and axes of pickups of zenith and apsidal angles are entered into correction unit and ground computer of inclinometer. EFFECT: enhanced precision and productivity of inclinometer operations. 2 cl, 5 dwg

IPC: G11C7/00
Filed: 1995-02-01
Abstract: The method for transformation of information words into the modulated signal distributes code words within the range of at least one group of the first type and of at least on group of the second type. The delivery of each of the code words that belong to the mentioned group of the first type, ensures the establishment of the encode mode of the first type which is determined by the mentioned group of the first type. The delivery of each of the code words that belong to the mentioned group of the second type, ensures the establishment of the encode mode of the second type which is determined by the mentioned group of the second type and by an accepted information word. Any chain of code words that correspond to the encode mode of the above second type does not contain an code words that contain in any other chain of code words which correspond to any other encode mode of the second type. At least one chain of code words contain some code word from the group of the second type which corresponds to some multitude of information words. Each information word of this multitude sets the encode mode of the second type which is different from the others, allowing thereby to discern a respective information word out of the mentioned multitude by means of the detection of the following code word.
