Abstract: Bi-directional (longitudinal and angular) three-dimensional volumetric microwave scanning of a whole roll or pallet of paper (FIGS. 3, 4), including three-dimensional volumetric mapping of internal properties and characteristics (moisture content, density, material uniformity, defects and types thereof, and variabilities thereof) of the roll or pallet of paper. Transmitted microwaves propagate through longitudinally and angularly defined portions of individual cross-sectional volumetric segments of the roll or pallet of paper. Microwave parameters (amplitude, phase) are perturbed by, and are a function of the internal properties and characteristics of, the contents of volumetric segment portions of the roll or pallet of paper. Microwave differential parameters (amplitude attenuation, phase shift) are calculated and used for calculating and determining values, relationships, two-dimensional graphs and maps, and, three-dimensional volumetric graphs and maps (FIGS.

Abstract: Method and device for non-invasively optically determining bulk density and uniformity of web material during in-line processing, by measuring and analyzing light scattered by volume segments of transported web material. Influence of process operating parameters of temperature, volumetric bulk material transport rate, type, and, physicochemical characteristics and properties, of the transported web material, on collecting and detecting the scattered light, are used for process correcting raw measured values of scattered light flux density/energy of scattered light exiting volume segments of the transported web material, for determining bulk density and uniformity. Pattern recognition and classification techniques are performed using the calculated bulk density and uniformity values of the web material. Bulk density is determined in the approximate range of from one to zero kilogram per square meter of web material, with corresponding measuring sensitivity of about one gram per square meter of web material.

Abstract: Using surface microwaves for measuring and determining density and/or moisture content of a material. Positioning material within a proximate free space region spanning immediately above surface of a surface microwave waveguide, the surface microwave waveguide includes an electrically conducting rectangular block and a dielectric rectangular insert element compactly fitting into the block. Transmitting microwaves into the first end of the surface microwave waveguide, a first portion of the transmitted microwaves propagate within the surface microwave waveguide and a second portion propagates within the proximate free space region including the material. Parameters (amplitude, phase, attenuation, and phase shift) of the propagating microwaves are perturbed by the material and are a function of density and/or moisture content of the material.
