Title: Bitstream format and reading and writing methods and apparatus therefor
Inventor: PORCHET JEAN-MARC
IPC: H04N5/926
Filed: 2004-03-30
Abstract: Image data having a bit depth of m bits, where m is not a power of two, may be divided into two parts for storage. The first part is the n most significant bits, where n is a power of two. The second part is the k least significant bits, where k = m-n and k<n. For example, 10-bit data may be separated into 8-bit and 2-bit parts. The 8-bit data for a given image is placed in the bitstream as a contiguous block with the end of the data aligned with a memory boundary, such as a page boundary. The 2-bit data is collected into bytes that are placed in the bitstream as a contiguous block. The block of 2-bit data is placed in the bitstream preceding and contiguous with the block of 8-bit data. Padding may be provided to align the beginning of the image data with a memory boundary. The image data for multiple images may be placed in the bitstream contiguously for storage. 10-bit data for an alpha channel, if any, also may be split into 8-bit and 2-bit parts. The 8-bit alpha data for a given image is placed in the bitstream as a contiguous block with the beginning of the data aligned with a memory boundary, such as a page boundary. The 2-bit alpha data is collected into bytes that are placed in the bitstream as a contiguous block. The block of 2-bit alpha data is placed in the bitstream subsequent to and contiguous with the block of 8-bit alpha data. Padding may be provided to align the end of the alpha data with a page boundary.      The alpha data for multiple images may be placed in the bitstream contiguously for storage.

Title: Composite material with synthetic composite matrix, method for producing said material, and its application
Inventor: ZUERBIG CLAUS
IPC: B32B3/26
Filed: 2004-07-02
Abstract: Described is a composite material having a flexible synthetic composite matrix, and a textile support web embedded therein. This composite material is characterized in that the composite matrix is based upon a cross-linked polyurethane, in that a textile support web is integrated into the polyurethane composite matrix, and in that a textile patterned surface is formed on at least one side of the polyurethane composite matrix. The textile support web is preferably comprised of a woven fabric or knitted fabric and is expediently arranged centrally within the polyurethane composite matrix. Advantageously, the process for producing this composite material consists in that during the cross-linking of a reactive parent material of a polyurethane, a textile support web is completely inserted into the parent material of the polyurethane matrix, which has been applied to a subcarrier, and a textile patterned surface is bonded to the cross-linking polyurethane layer, as soon as the inner stability will allow an even, single-sided embedding without the material breaking through, after which the polyurethane layer is reacted out. This material is characterized in that it can be bent, folded, and rolled, and can be sewn. It exhibits favorable properties with respect to flammability rating, color fastness, and resistance to fading. The composite matrix based upon a cross-linked polyurethane is preferably formed using a reactive high-solids polyurethane (PUR) system.

Title: A tool for gripping a pipe or rod
Inventor: TAYLOR RICHARD JAMES
IPC: F16D41/067
Filed: 2003-12-24
Abstract: A tool for gripping the circumferential outer surface of a pipe or rod (11) and comprising a pair of diametrically opposed arcuate shoes (10) each with a ball cage (14) having a plurality of balls retained by the cage. The shoes (10) have ramped surfaces upon which the balls will run so that when the shoes (10) are rotated about the central longitudinal axis of the pipe or rod (11) the balls become trapped between the ramp surfaces (18) and the surface of the pipe or rod, to grip same.

Patent CA-2512752-A1 (CA)
Inventor: AMINO YUSUKE
IPC: A23L27/30
Filed: 2003-12-26
Abstract: A process for producing a glutamic acid derivative represented by monatin, which comprises alkylating a 4-(protected hydroxy)pyroglutamic acid derivative with an alkylating agent to obtain a 4-(protected hydroxy)-4-alkylgultamic acid derivative and subjecting it to hydrolysis and protective-group elimination. The 4-(protected hydroxy)pyroglutamic acid derivative can be easily produced from hydroxyproline. The 4-(protected hydroxy)pyroglutamic acid derivative is selectively and stereoselectively alkylated in the 4-position and, after the alkylation, can be easily converted to a glutamic acid derivative. It can hence be advantageously used especially for efficiently producing monatin having a high optical purity.
