Title: Ascertaining spectral width of Doppler signals - measuring ratio of auto-correlation functions at null and pulse period displacement positions
Inventor: HASSLER DIETRICH
IPC: A61B8/06
Filed: 1990-11-29
Abstract: A method of measuring Doppler signal spectral width involves transmitting pulses of defined frequency into a region with moving particles, dividing the reflected echo signals into quadrature components, forming autocorrelation functions at null and pulse time displacement positions and determining the spectral width from their ratio. The cross-correlation component (Kiq (Tr)) at the pulse repetition time position is formed from the in-phase (i) and quadrature (q) components and the quotient multiplied by a correction factor before determining the spectral width. USE/ADVANTAGE - Esp. for measuring blood flows in medical diagnostics. Accurate measurement of Doppler spectrum variance and turbulence is achieved.

Title: Regulating tension in band of band press - using system which controls separate adjusting movements of ends of tensioning roller, and uses two independent positioning drives
Inventor: ROSCHER FRIEDER CLAUS
IPC: G01L5/10
Filed: 1991-08-07
Abstract: The tension in the band of a band press is regulated by adjusting the position of the axle of one tensioning roller by at least two independently controlled positioning drives. The distances of the axle of the tensioning roller produced by the positioning drives are measured separately and compared with each other; similarly the forces applied by those drives on to the roller are also measured separately and compared with each other; the two drives are operated synchronously in reference to a fixed bearing and in parallel so that any slack is taken up and the band is stretched; the difference between the two distances being used as the amount of regulation required; once a lower threshold force is reached the difference between forces applied to the tensioning roller is used as regulator and the tension in the band is adjusted to a preset value. ADVANTAGE - The system provides an improved a degree of uniformity in the tension in the band. As a result it produces high quality surfaces in the material made.
