  • Patent number: 11591421
    Abstract: A process for producing an ethylene copolymer, the process including: (a) contacting ethylene with at least one polar comonomer in the presence of at least one modifier and at least one free radical initiator in a tubular reactor under polymerization conditions including a pressure of from 225 to 270 MPa; (b) injecting the at least one free radical initiator into the reactor at a plurality of reaction zones spaced along the length of the reactor, wherein each reaction zone comprises an inlet and an outlet; (c) maintaining the temperature at the inlet of each reaction zone at 150° C. or less, and the temperature at the outlet of each reaction zone is at least 177° C.; (d) controlling the modifier flow at a rate of from 0.02 to 0.986 wt % of the copolymer; and (e) recovering the ethylene copolymer from the tubular reactor, is provided.

  • Patent number: 10997158
    Abstract: Methods, systems, and computer program products are described herein for updating big data tables using snapshot isolation. The tables may store data (e.g., as data objects) collected from different users. The tables are stored in a first data store. The data's metadata is stored in a second data store. The metadata comprises version numbers for the objects that correspond to a consistent version thereof. When an update process for the table is initiated, a coordinator locks the metadata, and. the objects are updated. If the update to the objects is successful, the coordinator commits the updates and obtains the new version numbers of the objects. If all the commits are successful, the coordinator atomically updates the metadata with the new version numbers and releases the lock. However, if a commit to an object is unsuccessful, a subsequent process rolls back the committed objects to the version numbers specified by the metadata.

  • Patent number: 9439846
    Abstract: The present invention relates to an oral care composition comprising catechins. We have found that the catechins tend to darken the color of the chalk based toothpaste due to its oxidation which happens at the high pH of the toothpaste. Once the catechins are oxidized and darken the color of the toothpaste it is no longer available as such for providing anti-inflammatory benefits. It is an object of the invention to provide a chalk based toothpaste formulation which does not turn substantially dark due to oxidation of catechins. The present inventors while working with oral care compositions comprising catechins preferably green tea catechins for providing anti-inflammatory benefits, surprisingly found that some selected zinc salts when added in particular quantities do not result in darkening the color of the toothpaste, and also, when stored, are able to deliver green tea catechins.

Once the catechins are oxidized and darken the colour of the toothpaste it is no longer available as such for providing anti-inflammatory benefits. It is an object of the invention to provide a chalk based toothpaste formulation which does not turn substantially dark due to ox illation of catechins.

  • Publication number: 20100251227
    Abstract: Optimization architecture for applications that uses a localization model in which localizable resources are separated from code. The resources are typically located in separate DLL files as binary blobs in a unique format. The format is designed for optimized performance and to accommodate various requirements of complex office applications. The binary blobs are produced by a resource compiler based on the format. The architecture includes a resource binary format that facilitates resource identification and lookup, optimization of memory paging by grouping and ordering resources according to runtime use, optimization by compressing resources with an optimal algorithm that is fast in decompression, fast reverse lookup of a resource identifier by resource content, resource grouping, resource substitution, branding, and resource runtime metadata (also referred to as user data).

  • Patent number: 7663511
    Abstract: In one embodiment, a computing device may compress a text file for storage by dynamically creating an encoding table. A storage device of the computing device may store an encoding table populated by string characters from a text file. A processor of the computing device may encode the text file by replacing a string character in a text string of the text file with a table index position of that string character in the encoding table. The processor of the computing device may decode the text file by replacing the table index position with the string character at the table index position in the encoding table.

  • Patent number: 7523469
    Abstract: Techniques for enabling inter-subsystem resource sharing are provided. The techniques include providing an RPC client on a first subsystem for acting as a proxy for a resource of a second subsystem. When the first subsystem receives a request from an application to access the resource, the RPC client may invoke a function of an RPC server associated with the second subsystem. The RPC server may load the resource on the second subsystem. The RPC client may then act as a proxy for the resource.
