Abstract: A free-flowing granulate of a powder-form or fine-grained component and a liquid component; the granulate containing at least 20% by weight of the liquid component, is prepared by moving the powder-form or fine-grained component in a mixer-granulator, adding the liquid component while mixing until a moist granulate having a particle size of at most 1.5 mm is obtained, subsequently coarsening the granulate thus obtained with an increase in temperature to a particle size of from 0.4 to 4 mm and optionally coating this coarse granulate with another powder-form and/or fine-grained component at 60 DEG  to 90 DEG  C. The optionally coated granulate is converted by lowering the treatment temperature into a dry-looking, free-flowing, coarse-grained product, which if desired, may be coated with another powder-form and/or fine-grained material. Despite the high percentage of a liquid component, the granulate thus obtained appears as a dry granulate and is free-flowing.

Title: Laser doppler speedometer
Inventor: TAKAMIYA MAKOTO
IPC: G01P5/00
Filed: 1990-02-09
Abstract: PURPOSE:To correctly detect speed of an object or fluid which moves at a low speed even if an oscillation wavelength of a laser beam varies by a method wherein the laser beam is incident on a moving body or moving fluid at a cross angle approximately equal to an angle made when diffracted light is emitted from two diffraction gratings. CONSTITUTION:A diffraction grating 10 of a grating pitch (d) moves at velocity Vg. When a laser beam I is incident on the moving diffraction grating 10, + or -n-th diffracted light beams 51, 52 generated on the diffraction grating 10 are subjected to positive and negative Doppler shifts + or - Vg/nd, respectively. A diffraction angle theta1 of the diffracted light beams 51, 52 satisfies sintheta1 = lambda/nd (where lambda is a wavelength). By applying the diffracted light beams 51, 52 by the use of mirrors 6, 6' in the form of two beams to an object 7 to be inspected which is traveling at velocity V so that respective incident angles are theta1, Doppler frequency F satisfies F = 2(Vg + V)/nd, and Doppler frequency which does not depend on a wavelength of the laser light can be obtained. Thus even if the velocity V is small, the frequency F can be high frequency wherein difference in frequency with low frequency components due to a change in a speckle pattern or the like can be sufficiently obtained.
