摘要： A wideband distributed or feedback amplifier monolithic microwave integrated circuit (MMIC) is disclosed that contains an integrated group delay equalizer circuit to compensate for the group delay variation of the amplifier circuitry. The MMIC amplifier is capable of achieving a predicted constant group delay with little variation over a wide frequency range. In addition, the group delay equalizer circuit enables the amplifier to achieve flat (constant) gain over a wide bandwidth, while maintaining constant group delay. Furthermore, the group delay equalizer circuitry requires only a small portion of the total MMIC area.

摘要： A process for the treatment of refinery oily sludges to produce an oily fraction that is reprocessed in the refinery into (i) salable products and (ii) a solid residue meeting environmental regulatory agency requirements for disposal in non-hazardous solid waste landfills. The process includes mixing the refinery oily sludge with a particulate filter aid and preferably a single solvent selected from refinery intermediate and product streams and contacting this mixture with plate filters in a closed filter vessel. A cake residue forms on the filter plates and a filtrate mixture of oil, water and solvent is produced. The filtrate is separated into an oily fraction and a water fraction. The oily fraction is rerouted to refinery operating units for processing into salable products. The water fraction is routed to a refinery water treatment system. When filter cake residue has built to a predetermined level, charge to the filter vessel is discontinued. The filter cake residue is washed with a predetermined quantity of solvent and then steam stripped to remove petroleum hydrocarbons to a desired residual level, e.g. less than about 1,000 ppm or less than 500 ppm. The steam stripped filter cake is then removed from the filter vessel for disposal in an environmentally approved landfill.

摘要： 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.

摘要： 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.

摘要： A small aspect ratio, high power MMIC amplifier is disclosed. The small aspect ratio MMIC amplifier is capable of achieving the same power levels as conventional power amplifier designs, but with an aspect ratio of near 1:1, versus 4:1 of conventional power amplifiers. The small aspect ratio MMIC amplifier layout uses two different types of FETs, with all gate fingers of both types of FETs running in the same direction. One type of FET is a conventional FET, in which the gate stripes run parallel to the direction of the output. In the conventional FET, the gate manifold and the drain manifold both generally extend in the x-direction (parallel to each other). The other type of FET has gate fingers that run perpendicular to the direction of the output. In this other type of FET, the gate manifold generally extends in the x-direction, while the drain manifold generally extends in the y-direction (perpendicular to each other). By using two different types of FETs, large gate width power FETs can be placed on two, three or four sides of the MMIC.
