Abstract: A radiation imaging system comprises a movable radiation source adapted to be disposed in a plurality of respective radiation source positions; a radiation detector and a collimator assembly configured to displace a collimator in a plurality of respective collimator positions, each of the collimator positions being coordinated with at least one of the radiation source positions such that a radiation beam emanating from the radiation source is collimated to limit radiation incident on the detector to a predetermined exposure area. Another radiation imaging system comprises a movable radiation source; a radiation detector; and a collimator comprising an adjustable geometry aperture assembly configured such that an adjustment of the aperture geometry is synchronized with the movement of the radiation source and coordinated with the radiation source position so as to limit the incident radiation to a predetermined exposure area at the detector.

Abstract: A splice connector includes a first coupling electrically connected to a first cable or conductor and a second coupling electrically connected to a second cable or conductor. Both couplings include at least one electrically conductive spade. The second coupling engages the first coupling so that the respective spades contact each other, thereby electrically connecting the two cables or conductors. Due to its construction and mass, this connector can be used in high temperature, high-G environments.

Abstract: A method for filling a compartment cavity, such as a refrigerative unit cavity, with a foam produced by an expansion and solidification of a foaming mixture of predetermined chemicals. A known amount of the foaming mixture is created in a test chamber cavity and preselected parameters (such as free surface height and pressure) are measured to obtain the average density and apparent viscosity of the foam as a function of time. A computer program uses the average density and apparent viscosity data to simulate the foaming process for various starting quantifies and starting locations of the foaming mixture. A preferred quantity and location are chosen from a particular computer run which satisfies predetermined fill criteria. The preferred quantity of the foaming mixture is then created at the preferred location in the compartment cavity.

Abstract: An energy efficient washing machine includes a cleansing fluid supply system, a washer basket having an agitator device for displacing the articles to be cleansed within the basket, and a closed loop water level controller coupled to the cleansing fluid supply system and to the drive system for the agitator. The fluid supply system includes a fill nozzle designed to provide a clothes-positioning spray pattern that serves to maintain the articles evenly distributed in the basket to enables the load sensing systems of the closed loop adaptive water level controller to function to accurately provide the optimal water level for cleansing. To accomplish this positioning of the articles to be cleansed, the fluid fill nozzle typically provides a fan discharge of fluid passing therethrough and is disposed at a cant angle with respect to the direction of rotation of the basket such that the fan discharge covers an area between the agitator assembly and the sidewall of the basket.
