Abstract: A method for removing contaminants from an process stream that includes the use of reticulated material to filter the process stream. The reticulated material also facilitate process stream flow distribution in process units. The reticulated material can be packed with a void space between a substantial number of the reticulated material that can be varied to enhance filtration and flow distribution. The method of filtering also provides a method of removing contaminants leaving process equipment. The methods can be used on a variety of process streams and process equipment. The reticulated material can include ceramics, metallic materials, and chemical vapor deposition elements. The reticulated material can be of various shapes and sizes, and can also be catalytically active.

Abstract: A filtering medium and method for removing contaminants from an organic-based feed stream that includes the use of a layer of ceramic filter units having a plurality of elliptical or trisoidal openings extending therethrough to filter organic-based feed streams and to provide liquid distribution upstream of the catalyst beds.

Abstract: Systems and methods for generating navigation signals for a vehicle in an auto-avoidance situation. In one embodiment the method includes analyzing two or more paths with respect to information about obstructions stored in a database. The method disclosed then selects a path and generates navigation signals, if an auto avoidance situation exists.

Abstract: A method and assembly for utilizing open-cell cellular solid material in a component separation unit to separate one or more process streams into component process streams having desired compositions. A method and assembly for using said open-cell cellular solid material to separate process streams into desired component process streams in a component separation unit, wherein the open-cell cellular solid material can include oxides, carbides, nitrides, borides, ceramics, metals, polymers, and chemical vapor deposition materials.

Abstract: The pecan confectionery according to the present invention comprises two overlapping pecan halves and an edible filling layer sandwiched between the two pecan halves. The filling layer can be any spreadable food product including but not limited to cream, ice cream, marshmallow, and caramel. In addition to enhancing the flavor of the pecan halves, the filling layer serves to hold the pecan halves together. Thus, the arrangement of the pecan confectionery allows one to enjoy a unique combination of flavors in a simple and convenient manner.

Abstract: An inspection system for identifying defects on the surface of an item includes an information processor mounted on a base assembly. A tray is used to move the item to an inspection station on the base assembly, and an illuminator is provided at the inspection station to illuminate the item from different visual perspectives. Importantly, the illuminator includes a plurality of different light sources. An N number of cameras and an M number of image processors are operated in concert to collect image data from the illuminated item. This image data is then analyzed using the image processors to compare the image data with a template image to detect defects in the item. In the operation of the inspection system, the tray, the illuminator, the cameras and the image processors are all centrally controlled and coordinated by an central information processor.

Abstract: An optical device for establishing a spatial orientation for a drill bit includes at least three light sources and two cameras. The first light source is used to silhouette the drill bit; a second light source is used to generate a reflection from a primary facet of the drill bit; and a third light source is used to generate a reflection from the margin of the drill bit. In sequence, the first camera responds to the first light source to establish an axial position for the drill bit on the axis. The second camera then responds to the second light source to establish a gross rotational position for the drill bit on its axis. Finally, the first camera is again used. This time it establishes a precise rotational position for the drill bit on its axis to establish the spatial orientation for the drill bit.

Abstract: A passive method and packaging system for thermally controlling the temperature of electronic equipment within a housing are disclosed. The packaging system provides for two cooling steps, each of which uses a different passive cooling technology. Cooling by changing the phase of Phase Change Material, assists in controlling internal ambient temperatures by limiting the effects of short term localized thermal phenomena which would otherwise further increase internal temperatures. Cooling is also provided for by switching on a second passive cooling means, preferably a heat pipe, as the internal temperature of the housing increases above a predetermined temperature and to switch it off as the internal temperature drops below the predetermined temperature. Turning the second passive cooling means on and off provides respectively, a low or high thermal resistance path between the interior and exterior of the housing.

Abstract: A portable milling apparatus is disclosed where said apparatus, in one embodiment, comprises a cutting head, a control mechanism and a power supply where said cutting head generally includes a frame, an axial displacement means, a rotary cylinder and alignment means.
