Abstract: A sealed centrifugal clarifier with a pre-sterilized and disposable container which lines the separation chamber is disclosed. More particularly, the centrifugal clarifier contains a feed port that allows a liquid-solid mixture to be continuously fed into the device wherein the solid is sedimented by rotation of the separation chamber and the clarified liquid is released into an outside receptacle through an effluent port. The throughput rate of the clarifier is adjustable and can be determined as a function of the fill radius of the separation chamber.

Abstract: An X-ray inspection device (10) for detecting a specific material of interest in items of various sizes and shapes (24A, 24B, 24C) includes an X-ray source system located at an inspection region and constructed to expose the examined item to at least one beam of X-ray radiation, and one or more X-ray detection systems (60, 80, 100). The X-ray inspection device also includes one or more dimension detectors (120) constructed to measure a selected dimension of the examined item, an interface system connected to receive X-ray data and dimension data, and a computer programmed to utilize the data for recognition of the specific material of interest and to indicate its presence in the examined item. Each detection system includes one or more arrays of X-ray detectors arranged in a linear, circular or semi-spherical geometry.

Abstract: An X-ray inspection device for detecting a specific material of interest (typically contraband, for example, weapons, drugs, money, explosives) in items of various sizes and shapes includes an X-ray source system located at an inspection region and constructed to expose the examined item to at least one beam of X-ray radiation, one or more x-ray detection systems located at the inspection region and constructed to detect x-ray radiation modified by the examined item. The X-ray inspection device also includes one or more dimension detectors constructed to measure a selected dimension of the examined item, an interface system connected to receive X-ray data and dimension data, and a computer programmed to utilize the data for recognition of the specific material of interest and to indicate its presence in the examined item. The X-ray detection systems detect transmitted and/or scattered X-ray radiation utilizing several different geometries.

Abstract: An equalization radiography system using specially shaped and arranged modulator pins which reduce artifacts by effectively smoothing variations in attenuation as between adjacent pins.
