Abstract: A waveguide/conduit clamp has a load bearing frame with slotted mounting provisions and two mated center rings, an inner circular member with a center cutout to accommodate a waveguide or other conduit member and an outer circular member with a circular cutout displaced from its centerline by a specified offset. Rotation of the outer member, while maintaining orientation of the central one, results in vertical and horizontal displacement of the cutout in the central unit. When proper vertical distance of the cutout is achieved, the clamp is moved in its slotted mounting base to provide final adjusted position of the central member's waveguide/conduit workpiece. Both circular members have slits allowing their placement around the workpiece and within the clamp's load bearing frame.

Abstract: A method of recovering light organic solvent from a liquid mixture containing the solvent and a process material, such as asphaltenes or coal liquefaction products. The solvent-process material mixture is treated in a solvent separation zone to separate a first vapor phase rich in solvent and a first liquid phase rich in process material. At least a portion of the liquid in the solvent separation zone is transferred to a mixing zone, where the liquid is intimately contacted with steam, under shearing conditions. The steam-liquid phase mixture thus produced is returned to the solvent separation zone and treated to separate a second vapor phase, rich in steam and solvent, and a second liquid phase, rich in process material and substantially depleted of solvent. Solvent is recovered from the first and second vapor phases.

Abstract: A method of separating a process material comprising oils, resins and asphaltenes into at least three fractions. The process material is mixed in a mixing zone with a solvent selected from the group consisting of paraffinic hydrocarbons having between about 3 and about 8 carbon atoms. The process material-solvent mixture is introduced into a first separation zone to form an asphaltene-rich first heavy fraction and a resin-rich intermediate fraction, separated by a first liquid-liquid interface, and to form a first light fraction, rich in solvent and oils, separated from the intermediate fraction by a second liquid-liquid interface.The first heavy fraction and the intermediate fraction are withdrawn from the first separation zone. The first light fraction is introduced into a second separation zone to separate a second heavy fraction, rich in oils, and a second light fraction, rich in solvent.

Abstract: Apparatus for mounting in a fluid separation zone for improving the separation of fluids of different densities. The apparatus includes a distributor mounted within the separation zone provided with fluid openings having packing means disposed thereabout.
