  • Publication number: 20080255338
    Abstract: A design method of batch falling strand devolatilizers is disclosed. The method includes following steps. Firstly, construct a database that contains data of batch falling strand devolatilizer vs. devolatilization of at least one kind of polymer. Then data in the database is substituted into a mass balance difference equation to get a backmixing parameter. When the backmixing parameter is zero or is approaching zero, a liquid diffusion stage efficiency equation having a film equation or a pool equation is integrated with the mass balance difference equation to get a devolatilization process efficiency equation. By means of a theoretical value of the backmixing parameter, a theoretical value of the process efficiency from calculation of the devolatilization process efficiency equation approaches the value of the process efficiency.

  • Patent number: 7295571
    Abstract: An improved type of application-specific integrated circuit block (ASIC) is disclosed that is optimized for use in a communications system, and is somewhat programmble through the use of particular data objects that can specify an instruction and operand for the ASIC. The ASIC can be multi-tasking to perform multiple receive or transmit operations, two different kinds of transmit or receive operations, and operaions for mulitple ports. The ASIC generally uses an input data decoder block for decoding an input data object; a computation logic block for performing application specific computations in connection with the input data object, and an output data encoder block for encoding an output data object based on the specific computations. Using a common memory, a set of such ASICs can be arranged in a form of logical (or logical hybrid) pipeline.

  • Patent number: 7286668
    Abstract: This invention discloses a method of protecting copyright of a digital video work by using a digital password technology and a digital watermark technology to prevent the unauthorized use of a digital video work. Such method adds password protection of two chrominance arrays of such video work in advance, so that when such video work is published on the Internet, it can only be played in color by a specified player. As long as a user enters the correct password into the specified player, a full color visual effect of such video work can be obtained. If other players are used to play such video work, only a partial gray-scale visual effect can be obtained. Users must request or buy a specific player and a password from the distributor of such video work to play the complete information to prevent piracy.
