Abstract: A CCR system 100,200 for removing and analyzing particles from a surface 104 of a substrate 102. A CCR 113 is selectively contactable with the substrate surface. The CCR rolls along the surface, which typically is drawn past the CCR as a continuous moving web on a roller 108, the CCR being rotatably mounted on an axle of the system. In a first embodiment 100, the CCR may be removed for off-line analysis of contamination. In a second embodiment 200, the CCR may remain in operation for real-time analysis of removed contamination. A video camera 122,222 scans the CCR surface and transmits images or data for visual and/or computer analysis of the contamination, which analysis may include, but is not limited to, computerized shape analysis of particles, areal distribution of particles, and composition of particles.

Abstract: The present invention provides more efficient, cost effective coke drum isolation valve devices and system as well as more efficient, cost effective methods for isolating the flow of matter from location to another in the delayed coker unit operation where the valve comprises a first seat; a second seat aligned with said first seat; a blind; a main body having an orifice dimensioned to align with an orifice in said line; wherein said main body is coupled to said line; an upper and lower bonnet coupled to said main body, wherein said bonnets may be removed in order to replace valve parts without separating the main body from the line; and a plate located inside a bonnet, wherein the plate comprises a planar surface that contacts a surface of the blind.

Abstract: A cleaner assembly for cleaning a roller comprising a tape unwinder and winder for holding and dispensing adhesive tape which may be a continuous strip or may comprises discrete sheets of adhesive tape wound on top of each other. The winder and unwinder are connected to a drive by a timing belt. Thus a length of tape may be wound back and forth on a roller surface by alternating the rotation of the drive. The tape is passed around a backing roller to press the tape against a roller to be cleaned. In a second embodiment, the tape roll comprises a plurality of sheets of tape wound on top of each other. To remove a spent outer sheet, the outer sheet carrying the transferred particles is transferred to a continuous tape roll, exposing a fresh sheet on the sheeted tape roll which is then ready for renewed cleaning service.

Abstract: A coke drum bottom de-heading system having an internal shroud enclosure and a shroud end cap opened by a flange to a coke bottom de-heading valve capable of accepting the end of a gate valve upon actuation. Acting in coordination with the shroud enclosure to prevent the escape of steam is a gate seal assembly having a gate seal slidably engaged against the sliding gate to prevent the passage of steam thereby.

Abstract: The present invention relates to methods for determining and predicting the efficacy of therapeutics for the treatment of an individual with asthma based on that individual's ?2-adrenergic receptor. The invention finds particular applicability to the treatment of an individual with asthma with an inhaled corticosteroid or a leukotriene receptor antagonist who is homozygous for arginine at position 16 of the ?2-adrenergic receptor.

Abstract: An ending apparatus for positioning elongate objects comprising, in combination, object singulating equipment for separating a plurality of elongate objects in an inlet area into single objects while moving the objects in a first direction to an outlet area, and object support rollers intermediate the inlet and outlet area for supporting a separated, single elongate object. The object support rollers are adapted to move the elongate object in a second direction toward a reference surface independently of the object's movement in the first direction on the singulating device. The reference surface stops movement of the elongate object to establish a pre-determined position for the elongate object. Establishing the position of the object permits more efficient handling during further processing.
