Abstract: A set of N standard bin count distributions may be generated by irradiating a test radiation detector system with an X-ray beam attenuated by a respective one of N different K-edge filters for each of the at least one X-ray source energy setting. Energy bins of detectors of a target radiation detector system may be calibrated by generating measured bin count distributions for each calibration setting in which a respective one of the N different K-edge filters attenuates a source X-ray beam. Calibration parameters of the detectors of the target radiation detector system may be adjusted to match each of the measured bin count distributions to a corresponding standard bin count distribution. In addition, energy resolution of the radiation detectors can be measured and calibrated by fitting a portion of the measured X-ray spectrum near a K-edge to a fitting function.

Abstract: An apparatus for heating or cooling sealed food pouches, another apparatus for moving the same and a third apparatus adapted to transfer the pouches are disclosed. The three apparatuses are designed to function as an integrated food pouch handling system, but may also be used separately. The first apparatus consists of a large bath partially filled with circulating hot or cold liquid, following a course in which whirlpools are created. The food pouches are placed in the bath and are carried by the moving liquid until they have attained the desired temperature. The second apparatus consists of a conveyor mounted on a cart. The conveyor is tiltable so that one end thereof can be placed in the bath to automatically retrieve the food pouches. The third apparatus is a large vat to receive the food pouches placed therein by the conveyor.

Abstract: A stripline non-reciprocal multi-octave phase shifter which consists of a matched dielectric slab located along the first ferrite slab edge which corresponds to the magnetic wall and of lumped loads placed along the propagation direction along the same edge of the second ferrite slab. The other edge of the slabs are associated with identical composite media terminated by a lump impedance which consists of a short-circuit between the three conductors in the preferred embodiment of the invention. A high permittivity dielectric slab near the other edge of each of the ferrite slabs is preferably part of said composite media.

Abstract: In a surface wave isolator consisting of two gyromagnetic slabs a conductive strip between said slabs, means to establish a magnetizing field within said slabs, a two part load is associated side by side with said slabs and the strip extends also between the two parts of the load. A first part of the load is a continuous load parallel to the strip, a second part of the load is a plurality of localized absorbing means placed along the propagation axis and parallel to said strip. The impedance of the localized absorbing means is matched to the impedance of an unwanted parasitic propagation mode at the corresponding place.
