    摘要: This invention makes possible substantially continuous flow of uniformly distributed hydrogen and hydrocarbon liquid across a densely packed catalyst bed to fill substantially the entire volume of a reactor vessel by introducing the fluids as alternate annular rings of gas and liquid (i.e. a mixture of liquid hydrocarbon and a hydrogen-containing gas) at a rate insufficient to levitate or ebullate the catalyst bed. Catalyst are selected by density, shape and size at a design feed rate of liquids and gas to prevent ebullation of the packed bed at the design feed rates. Catalysts are selected by measuring bed expansion, such as in a large pilot plant run, with hydrocarbon, hydrogen, and catalyst at the design pressures and flow velocities. The liquid and gas components of the feed flow into the bed in alternate annular rings across the full area of the bed. At the desired flow rate, such catalyst continually flows in a plug-like manner downwardly through the reactor vessel by introducing fresh catalyst at the top of the catalyst bed by laminarly flowing such catalyst in a liquid stream on a periodic or semicontinuous basis. Catalyst is similarly removed by laminarly flowing catalyst particles in a liquid stream out of the bottom of the catalyst bed. Intake for such flow is out of direct contact with the stream of gas flowing through the bed and the flow path is substantially constant in cross-sectional area and greater in diameter by several times than the diameter of the catalyst particles. The catalyst of this invention produces a plug-flowing substantially packed bed of hydroprocessing catalyst which occupies at least about 75% by volume of the reactor volume.

    摘要: Expandable and expanded plastic materials having a majority of alkyl acrylate monomeric repeat units are disclosed. These materials when expanded have a volume expansion of at least 60 and maintain that volume expansion for a period of at least 30 minutes under expansion conditions after reaching the volume expansion of 60. Expandable and expanded plastic materials having a majority of alkyl acrylate monomeric repeat units and an inhibitor for the monomer(s) and a crosslinker incorporated into the plastic material upon monomer polymerization are also disclosed. Also disclosed are expandable and expanded plastic materials having a majority of alkyl acrylate monomeric repeat units with blowing agents of 2,2-dimethylbutane, 2,3-dimethylbutane or mixtures of one or both with 1-chloro-1,1-difluoroethane or mixtures of at least 30 percent of one or both with other volatile blowing agents.These specific types of formed patterns and core assemblies, wholly or partially formed from the destructible expanded closed-cell cellular plastic materials of the present invention have a decreased tendency to form nonvolatile residue during the casting of metals such as iron. Superior castings are thereby obtained without resort to uneconomic casting methods.Further disclosed is a method of casting metal castings using the disclosed expanded plastic material articles (Lose Foam or Evaporative Pattern Casting). The disclosed expanded plastic material articles are especially preferred for metal castings having a final carbon percentatge of 1.8 weight percent or less in the final casting.

    摘要: Feed cathode for an electrolytic cell with a feed conduit suited to pass a metal compound therethrough from a source to an electrolyte in the cell. The feed cathode includes a member surrounding and substantially entirely enclosing at least an outlet of the conduit. The member is at least partially formed of an electrically conductive foraminous body suited to pass the electrolyte and ions of a multivalent metal compound therethrough. Preferably, the foraminous body has an electrical coefficient of greater than zero to about 1 and a flow coefficient of from about 0.1 to about 300.

    摘要: A file operations engine is provided that manages many user interactions with their files via a computer system. The operation engine may provide a user with the option to keep both files that have a file name conflict. It may further permit the user to rename a file involved with a file name conflict. The operations engine may also automatically rename one of the files of a file name conflict by appending a character to a root of the filename. The character may include the lowest integer available for the root in a destination for the files. The operations engine may provide the option to keep both files as part of a pre-calculation of potential errors for a requested operation. The operations engine may place file name conflicts in an error queue and permit the user to select an option to keep both files after the conflict is encountered.

Dialogs may be provided to a user to satisfy errors listed in an error queue and/or identified while pre-calculating potential errors. Methods are provided for handling file operations errors and for interacting with a user interface for file operations. Computer-executable instructions for implementing the disclosed methods are stored on computer-readable media.

The back panel of the CTMS has a light source, for example an LED associated with each connector on the back plane. When a circuit card is plugged into the front plane of the CMTS the card activates the light source on the back plane to indicate whether an active channel is connected to the connector and what type of channel the active channel is.
