  • Patent number: 8795521
    Abstract: A nut shell filter allows the shell filter media to be scrubbed without being removed from the filter vessel. In order to protect the vessel from pressure surges which can occur during the scrubbing cycle, pressure applied during the beginning of the scrubbing cycle is contained within a scrubber tube such that the filter vessel is not subjected to pressure surges which occur at the beginning of the scrubbing cycle. The scrubber tube and scrubber filter tube may either be disposed within the filter vessel or outside of the filter vessel.

  • Patent number: 8491951
    Abstract: Frying processes utilizing cooking oil at elevated temperatures can cause various degradation effects in the oil including oxidation, hydrolysis and/or polymerization. In the absence of additives to protect the oil, the nutritional profile and cooking performance of degraded oil diminishes the quality of food cooked therein. The disclosed methods and compositions provide beneficial and cost effective improvements in the cooking performance of oil used at elevated temperatures, for example, in food frying equipment.

  • Patent number: 8360646
    Abstract: A compound conduit containing inner and outer conduits with apertures in the former that are angled to direct jets of fluid in a rearward direction from the inner conduit into the annular space is used to draw sludge or undesirable material from a vessel without imposing a vacuum on the system. In conjunction with the compound conduit is a rotary tube seal that allows the conduit to be mounted to an orifice in a tank wall and pivoted or rotated over a range of angles. A tubing drive mechanism grasps the tubing at locations well removed from the distal end and causes the tubing to travel in the direction of the tubing axis. The gripping members in the mechanism engage the sides of the tubing and are capable of shifting position relative to each other to accommodate changes in the curvature of the tubing.

    Abstract: Apparatus and methods for indicating seal leakage between two components are provided. In one aspect, apparatus and methods for directing material penetrating a leaking nozzle repair shield seal to a predetermined indication point such that a user viewing such indication point is alerted to the leaking seal condition is provided. In one aspect of the present invention, a channel having six distinct sections directs the material to the indication point. These six channel sections include two annular sections extending about the periphery of a main cylindrical section and an inwardly facing surface of a flange of the nozzle repair shield. These six channel sections further include a reservoir and interconnecting channel sections. Also, a sleeve for encircling the outwardly facing surface of the main cylindrical section of the nozzle repair shield is provided and the indication point may be provided in the form of a reservoir.

  • Patent number: 7772302
    Abstract: Scrap plastic is treated for incorporation into asphalt-aggregate compositions by first shredding the plastic, then heating the shredded plastic to harden any pieces of film or flexible plastic and to generally reduce the size of the shreds without decomposing the plastic, and then grinding the heat-treated pieces to a size that can be blended with an aggregate. The blend is then combined with an asphalt binder to produce an asphalt-aggregate composition. No discrimination among, or selection of, specific types or classes of plastic is required.

  • Publication number: 20080271639
    Abstract: An asphalt mastic is prepared by combining spent activated carbon, that has not been regenerated, with liquid asphalt to achieve a composition that is useful for a variety of applications for which asphalt is used, including aggregate compositions and roofing materials. The activated carbon can also serve as a foaming initiator for the production of foamed asphalt. Still further, the activated carbon can be used as coking unit feedstock and as a quencher for a delayed coking unit.

  • Patent number: 7025822
    Abstract: An asphalt mastic is prepared by combining comminuted waste solids from a petroleum refinery with liquid asphalt that is either a hot asphalt or an asphalt emulsion. The resulting composition is similar in performance to Trinidad Lake Asphalt and is useful either on its own or as a binder for asphalt-aggregate compositions, in both cases optionally in combination with polymeric additives that are common in the asphalt industry.

  • Patent number: 7025078
    Abstract: A valve seat and a valve assembly incorporating such valve seat form tight dual seals with glass lined nozzle of a reagent or reaction vessel. This reduces or eliminates cavities and crevices between the value seat and the nozzle where residues or contaminants can accumulate. Additionally, the present valve assembly comprises flush ports to permit the valve seat and the valve to be cleaned-in-place. This eliminates the need to disassemble the valve seat and/or the valve to remove the contaminants, thereby minimizing process “down time.

  • Patent number: 6668912
    Abstract: The specification and drawings describe and show an embodiment of and method of forming a liquid flow through heat exchanger structure cast in a metal matrix composite. The composite comprises a preform reinforcement material infiltrated with molten metal. The composite reinforcement material is injection molded around the heat exchanger structure allowing for intimate contact between the composite and structure. The composite formed has a specific coefficient of thermal expansion to match an active heat-generating device mounted thereon. The present invention allows for enhanced thermal and mechanical properties by eliminating voids or gaps at the composite to heat exchanger structure interface, these voids or gaps being present in prior art fabrication methods or induced by usage due to thermal cycling of prior art composites.
