Abstract: An adjustable rotor and/or a radial piston machine which may utilize an adjustable rotor. The rotor has a primary eccentric rotatable with a shaft and a secondary eccentric adjustable in position relative to the primary eccentric. The radial piston machine includes a plurality of piston cartridges arranged radially around the shaft and both high pressure and low pressure fluid distribution systems. Multiple units may be axially coupled. A single unit may handle a variety of fluids in various combinations.

Abstract: A printed circuit board has a base made from fibers (e.g., ceramic) and an inorganic coating (e.g., silicon carbide) covering the fibers to provide the base with inorganic properties. The base may have a particular coefficient of thermal expansion (CTE) as by providing the fibers with particular characteristics in the plane of, and perpendicular to, the base. The base may be isotropic thermally as by disposing the fibers in two adjacent transverse layers. An inorganic material (e.g. copper) on the base provides a radio frequency barrier. An inorganic material (e.g., silicon dioxide) on the RF barrier constitutes a dielectric insulator. An electrically conductive layer (eg. copper) partially covers the dielectric layer in a pattern defining an electrical circuit. A dielectric material (eg., silicon dioxide) fills the remaining space in this layer in a flush relationship with the conductive layer.
