Abstract: A weld shield device for facilitating end-to-end welding of two pipe segments having fiberglass liners. The weld shield device includes an insulation material applied about the outer surface of a sleeve body. The sleeve body helps establish a welding gap between the two pipe segments. The insulation material reduces the heat transfer from the welding operations to the fiberglass liners. Additionally, a method of joining two pipe segments with fiberglass liners is provided, which includes connecting a first end of a weld shield device to a first pipe segment and connecting a second pipe segment to the second end of the weld shield device with the weld shield device being partially in a cutout portion of the fiberglass liner. Then, the two pipe segments are welded together. Insulation material on the weld shield device reduces the heat transfer from the welding operations to the fiberglass liners.

Abstract: A scalable pattern methodology defining positions of synchronization symbols, pilot symbols and data symbols for various numbers of sub-channels in a multi-carrier communication system. A base pattern (510) is defined identifying positions of data symbols, synchronization symbols and pilot symbols for a first number of sub-channels corresponding to a first bandwidth.     The base pattern is replicated or scaled to form an expanded pattern (512, 514) identifying positions of data symbols, synchronization symbols and pilot symbols for an expanded number (M) of sub-channels corresponding to a second bandwidth. The pattern methodology may be implemented by a transmitter (100) having subdivided an original information signal into M bit streams and having encoded each of the M bit streams to 16QAM symbols to form M symbol streams, by inserting synchronization and pilot symbols into each of the M symbol streams at positions determined by the expanded pattern. The pattern methodology allows a receiver (600) to perform pilot interpolation in the M symbol streams with the same set of pilot interpolation filters that would be required to perform pilot interpolation in the symbol streams of the base pattern.

Abstract: The present invention is directed to composite filters and methods for preparing same. More specifically, it is directed to filter laminates of multiple discreet layers of material bonded together, with at least one of t he layers being an asymmetric membrane. The laminates may be prepared using a lamination apparatus including an unwind (10) for, e.g., a low melting point polypropylene nonwoven material (12), a membrane unwind (14) for, e.g., a polyvinylidene difluoride membrane (16), and an unwind (18) for, e.g., a polyester nonwoven material (20). An adjustable, lateral spring force is applied to the unwind to maintain the stiffness of the material, thereby preventing formation of wrinkles in the laminate (22). Adjustable rollers (2 4) provide additional tension and also aid in wrinkle elimination. The layers (12, 16, 20) are pulled out from the unwinds (10, 14, 18) and over the heat shoe (26) by feeding the resulting laminate (22) between two drive rollers (30) situated after the heat shoe (26). A rewind (32) winds up the full widt h laminate (22).

Abstract: A signal adaptive filtering method for reducing blocking effect and ringing noise, a signal adaptive filter, and a computer readable medium. The signal adaptive filtering method capable of reducing blocking effect and ringing noise of image data when a frame is composed of blocks of a predetermined size includes the steps of: (a) generating blocking information for reducing the blocking effect and ringing information for reducing the ringing noise, from coefficients of predetermined pixels of the upper and left boundary regions of the data block when a frame obtained by deconstructing a bitstream image data for inverse quantization is an intraframe; and (b) adaptively filtering the image data passed through inverse quantization and inverse discrete cosine transform according to the generated blocking information and ringing information. Therefore, the blocking effect and ringing noise can be eliminated from the image restored from the block-based image, thereby enhancing the image restored from compression.

Title: Method and apparatus for reducing latency and message traffic during data and lock transfer in a multi-node system
Inventor: CHANDRASEKARAN SASHIKANTH
IPC: G06F9/46
Filed: 2002-05-08
Granted: 2010-04-13
Abstract: A method and apparatus are provided for improving the performance associated with transferring a data item and obtaining a lock in a multi-node system by interpreting the block transfer message as a lock grant message. Typically when a Holder of a data item transfers a data item (e.g. block) to a Requestor of that data item, the Holder will down-convert its lock for that data item and send a message to the Master of this data item indicating that a down-convert has been performed. Subsequently, the Master sends a lock grant message to the Requestor of the data item to inform the Requestor that it has been granted a lock for the data item. By interpreting the block transfer message as a lock grant message, the down-convert message and the lock grant message can be eliminated, which results in improved performance.

Abstract: A cheese substitute to imitate grated parmesan cheese comprises a protein or other bland tasting edible particulate combined with a vegetable fat component and a salt along with flavouring to approximate the taste and smell of parmesan cheese. The preferred choice of protein or edible particulate source is a full fat pre-cooked soya flour. The vegetable fat chosen is one suitable to act as the binding as well as mixing matrix for the cheese substitute. Thus, a vegetable based fat such as partially or fully hydrogenated vegetable oil commonly known as "Vegetable Shortening" is used. Fine grain sodium chloride is preferred as the salt in order to allow ready and discrete combination with the other constituents of the cheese substitute.
