    Abstract: Apparatus and methodology for the ultralow temperature processing of metallic, carbide, ceramic and plastic parts and items to materially increase their wear, abrasion, erosion and corrosion resistivity, stabilize their strength characteristics, improve their machinability and provide stress relief. The cryogenic treatment processing is carried out in an insulated box-like treatment chamber which includes a perforated platform extending parallel to and spaced above the bottom of the chamber. Parts and items to be treated are supported on the platform and cryogenic liquid is introduced to the chamber below the platform in accordance with a time-temperature program which reduces the temperature of the parts and items in stages to -320.degree. F. by initial cooling of the parts and items by evaporating vapors from the cryogenic liquid pool in the space below the platform and thereafter by partial or substantial submersion of the parts and items in the cryogenic liquid. After a soak period at the -320.degree. F. temperature level, the temperature of the parts and items in the treatment chamber is raised to ambient by controlled evaporation of the cryogenic liquid therein. Temperature and liquid level monitoring devices are mounted in the treatment chamber and information derived therefrom is utilized by a process controller to direct the supply of cryogenic liquid to the treatment chamber in accordance with the desired temperature descent and ascent profiles for the weight of the parts within the chamber.

    Abstract: The method comprises basically (1) fixedly securing, as by welding, an air inlet header between an air ring at a predetermined location point and the bottom of the regenerator for a primary support, (2) connecting other elongated supports under the air ring as secondary supports, (3) pivotally mounting slip rings on parallel pivot pins on opposite ends of each of the secondary supports and inserting them into corresponding pairs of sleeves mounted oppositely on the air ring and regenerator, (4) aligning each support so that its corresponding pivot pin is normal to a line between each pin and the predetermined location point, and (5) welding the slip rings in their respective sleeves with the supports so aligned to provide pivotal movement about the slip ring pins for eliminating any bending stresses due to thermal expansion or contraction when operating in the 1,100.degree. F.-1,400.degree. F. heat range of a regenerator in a fluid catalytic cracking unit. A support assembly assembled by the above or similar method is disclosed.

    Abstract: A rotating ball valve assembly includes a rotatable ball element. The rotatable ball element includes a first side portion, a second side portion, and a central passage. One of the first and second side portions includes first and second outwardly projecting pin elements. A sliding sleeve assembly includes a sliding sleeve member having a first guide track with a first force reducing profile associated with the first outwardly projecting pin element and a second guide track having a second force reducing profile associated with the second outwardly projecting pin element. The sliding sleeve member is shiftable relative to the first and second tubular members to selectively pivot the rotatable ball element between an open orientation and a closed orientation.

    Abstract: An electro-hydraulic actuator includes a housing having an interior portion a first opening and a second opening, a transducer is arranged in the interior portion. The transducer includes a sensor operatively coupled to a signal source at the first opening. A selectively activatable valve component is arranged at the second opening. The selectively activatable valve component maintains a desired pressure in the interior portion of the housing. An actuator is operatively coupled to the transducer and operable to activate the selectively activatable valve component exposing the interior portion to a volume of fluid in response to a signal from the transducer to activate a downhole system.

    Abstract: Systems and methods for detecting defects on a wafer are provided. One method includes generating output for a wafer by scanning the wafer with an inspection system using first and second optical states of the inspection system. The first and second optical states are defined by different values for at least one optical parameter of the inspection system. The method also includes generating first image data for the wafer using the output generated using the first optical state and second image data for the wafer using the output generated using the second optical state. In addition, the method includes combining the first image data and the second image data corresponding to substantially the same locations on the wafer thereby creating additional image data for the wafer. The method further includes detecting defects on the wafer using the additional image data.
