Patent DE-19654815-A1 (DE)
IPC: B23C5/20
Filed: 1996-12-31
Abstract: The tool is for fixing to a base body, and has two or more cutting edges (5,6) onto which the peripheral surfaces (7-9) join. As an alternative to the surfaces being on a common circle, they can have different centres. As a further alternative, they can form sections of an ellipse, hyperbola, etc., formed by contour grinding, and they can join adjacent cutting edges to each other. The edges can form the flanks of one or more arms extending radially from a main portion, while the peripheral surfaces are formed on the arms.

Title: Gasification of lump wastes and residues, destroying organics and producing non-leaching glassy slag
Inventor: MARTIN HEINZ
IPC: F26B5/06
Filed: 1997-01-25
Abstract: This new method exploits lump wastes and residues. It combines deep freezing with an in-flight gasification process. This yields a gas, predominantly containing hydrogen and carbon monoxide and free of organic compounds. In this novel process, the optionally pre-dried and pre-comminuted residues and waste (1) pass through deep freezing at -120 deg C to -190 deg C. The material is embrittled (3) for fine comminution, preferably by cold grinding (4), to produce a particle size less than 0.5 mm, suitable for in-flight gasification (10). Forced heating, dries the material to a water content establishing ready flowability.

Title: Arrangement for measuring electrical conductivity of liquids using probes and to control probe functions
Inventor: PRASSER HORST-MICHAEL DR
IPC: G01N27/07
Filed: 1997-02-07
Abstract: The arrangement has two probes each consisting of a central measurement electrode enclosed by a reference electrode. The probes are located at a defined distance from one another and are both in contact with the fluid to be measured. A voltage is applied to the measurement electrode of one probe (1) (active probe) and the resultant current (I2) from the measurement electrode of the second (2) (passive probe) is recorded. The current provides a measure of the conductivity of the conductivity of the fluid. In addition the current (I1) from the active probe is recorded as a measure of the its insulation resistance referred to the reference potential. A switching appliance (S1) periodically exchanges the role of passive and active probes to monitor the insulation resistance of both probes to check the correct functioning of the measurement arrangement

Abstract: The invention relates to a method for determining exact velocity of a rotating component, especially the velocity of a motor vehicle wheel, in which existing inconsistencies are scanned along the circumference of the rotating component and the temporal occurrence of discontinuities in velocity are determined. During the method for determining exact velocity of a rotating component, the dynamics of the rotating component are reliably determined despite manufacturing tolerances of incremental disk and eccentricity of the rotating component. According to the invention, an adjustment value is determined from the actual distribution of the discontinuities on the rotating component, said valve being used to determine the corrected velocity.
