摘要： A gas bearing structure including a cylindrical core and a cylindrical sleeve. The core has a radially outwardly facing surface with longitudinal and circumferential grooves formed thereon. The sleeve has a radially inwardly facing surface that sealingly abuts the outer core surface. The inwardly facing sleeve surface bridges over the grooves, defining fluid, preferably gas, flow paths within each groove. The gas flow paths permit gas to flow from the workspace to radial passages formed through the sleeve sidewall, thereby forming a gas bearing.

摘要： A method of forming a wound roll, such as a regenerator, including the steps of inserting wires at the lateral edges of an elongated strip as the strip is being wound around a spool. Spacers, such as localized bumps, are formed on the strip to space strip layers apart to form uniform gaps. An offset is added to the angle of rotation between each spacer-forming step to inhibit the nesting of bumps in the cavities of adjacent strip layers.

摘要： The free piston cooler transient temperature control system of the present invention eliminates collisions during the transient cool-down period in a free piston cooler upon start-up. The transient temperature control system incorporates a free piston cooler, having a cold head and a warm end, a cold head temperature sensor, a relational interface, and a temperature controller. The cold head temperature sensor senses the temperature of the cold head and generates a temperature signal. The relational interface is in communication with the temperature signal and contains a predetermined relationship between the cold head temperature and a maximum piston stroke during the transient cool-down temperature range. The relational interface generates a transient range maximum allowable stroke signal from the temperature signal and the predetermined relationship. The temperature controller is in communication with the relational interface and limits the piston stroke during the transient cool-down temperature range to prevent collisions.

摘要： Un crioenfriador que tiene dos modos de operacion de modo que es ampliado el rango de operacion, su sistema de cojinetes de gas es mantenido en una condicion que se puede operar y puede utilizar la regulacion de la carrera del embolo para la eficiencia de la energia. El regulador de la carrera del embolo regula la carrera del embolo cuando la carrera del embolo comandada excede la carrera minima y mantiene la carrera minima cuando la carrera comandada es menor que la carrera minima. Un calentador aplica energia del calentador a la carga termica cuando la carrera del embolo comandada es menor que la carrera minima del embolo. Un sistema de control de retroalimentacion de circuito cerrado es utilizado el cual tiene dos ramificaciones de su pata dinamica. Una ramificacion controla la ramificacion del crioenfriador y la segunda ramificacion paralela controla la regulacion del calentador.

摘要： A method of forming a heat exchanger apparatus on a housing wall. The heat exchanger includes inner and outer annular rings. The rings have heat radiating, high surface area fins attached on oppositely facing surfaces. The inner ring has a radially outwardly facing surface that abuts the interior surface of the housing sidewall. The outer ring has a radially inwardly facing surface that abuts the exterior surface of the housing sidewall. When displaced longitudinally along the ring axes, which are coincidental, the sidewall is clampingly engaged therebetween, and an excellent thermal flow path is formed. Heat transferred into the inner fins from a working gas is conducted to the inner ring, through the sidewall, into the outer ring, then into the outer fins. Air impinging upon the outer fins absorbs the heat from the outer fins.

摘要： Una estructura de cojinete de gas incluye un nucleo cilindrico (30) y un manguito cilindrico (50). El nucleo (30) tiene una superficie orientada radialmente hacia fuera con ranuras longitudinales y circunferenciales formadas sobre ella. El manguito (50) tiene una superficie orientada radialmente hacia adentro que sella apoyandose contra la superficie externa del nucleo. La superficie del manguito (50) orientada hacia adentro, forma un puente sobre las ranuras, definiendo trayectorias de flujo de fluido, preferiblemente de gas, dentro de cada ranura. Las trayectorias de flujo de gas permiten al gas fluir del espacio de trabajo a los pasajes radiales a traves de la pared lateral del manquito, formando por lo tanto un cojinete de gas.
