Abstract: A compression molding apparatus includes a mold of a first material having a first coefficient of thermal expansion and a plug of a second material having a second coefficient of thermal expansion different from the first coefficient of thermal expansion. The mold has a cavity into which the plug is placed such that the mold and plug are disposed relative to one another providing a gap therebetween having a first volume for holding a body that at least partially fills the gap when the mold and plug are at a first temperature and for molding the body into a molded product when the mold and plug are subjected to a second temperature that causes one of the first and second materials of the mold and plug to change in size more than the other and thereby change the gap to a second volume different from the first volume and compress the body.

Abstract: A dehumidifier for an x-ray detector includes a box having an inlet, an outlet, and a drain. A thermo-electrical element includes a cold plate disposed inside the box for cooling air channeled therethrough, and an opposite hot plate disposed outside the box for liberating heat. Air is cooled inside the box for condensing moisture therefrom which is removed by the drain, and the cooled air is heated for reducing relative humidity thereof. The resulting dry air is channeled to a housing protecting the x-ray detector.

Abstract: An imaging apparatus, such as an MRI system, contains at least one layer of soft magnetic material between the yoke and each permanent magnet. This imaging apparatus may be operated without pole pieces due to the presence of the soft magnetic material. The permanent magnets may be fabricated by magnetizing unmagnetized alloy bodies after the unmagnetized alloy bodies have been attached to the yoke.
