Title: Method and apparatus for controlling the drying process in a drying section of a paper machine or the like
Inventor: SUNDQVIST HANS
IPC: D21F5/00
Filed: 1999-12-03
Abstract: A method and apparatus for controlling the drying process taking place in the dryer section of a paper machine or the like. The total drying efficiency required in the dryer section is first calculated by means of a method known as such, and an optimal drying efficiency distribution is compiled. Using the optimal drying efficiency distribution, the dryer section is divided into two or more imaginary drying segments which differ in their drying action, in at least one of which segments there are at least two dryer units using different forms of energy and/or at least two separately adjustable dryer units using the same form of energy. The total drying efficiency obtained is divided, by means of an optimisation method known as such, between the said different drying segments in such a way that a good drying efficiency distribution is achieved in terms of the quality of the web being dried.

Title: Process for the preparation of 3,4-dihydroxybutanoic acid and derivatives thereof from substituted pentose sugars
Inventor: HOLLINGSWORTH RAWLE I
IPC: C07D307/33
Filed: 2000-02-17
Abstract: A process for the preparation of 3,4-dihydroxybutanoic acid (I) and 3-hydroxy-.gamma.-butyrolactone (V) thereof from a 3-leaving group substituted pentose source is described. In particular, the process relates to the synthesis of (R)-3,4-dihydroxybutanoic acid and (R)-3-hydroxy-.gamma.-butyrolactone from a 3-leaving group substituted L-pentose sugars. The process uses a base and a peroxide to convert the pentose source to the chiral 3,4-dihydroxybutanoic acid compound. The chiral 3,4-dihydroxybutanoic acid can be further converted to 3-hydroxy-.gamma.-butyrolactone by acidification. The chiral compound is useful as a chemical intermediate to the synthesis of various drugs and other products.

Patent CA-2364072-A1 (CA)
Inventor: MAUNG EDWARD AUNG KYI
IPC: H04L1/00
Filed: 2001-11-30
Abstract: A method for transmission of digital data in a form of data packets through links carrying data packets with error correction, includes the steps of enveloping a sent packet data, first with an error detection scheme, and secondly with an error correction scheme. The error correction applies to both the sent packet data and to the error detection field. If an error in either of these fields occurs, the error correction scheme attempts to correct it. Error correction may fail in which case the packet is dropped. If error correction does not fail, there is still a possibility that there was an error which error correction did not correct correctly, or did not detect at all because the power of the correction scheme was exceeded. In these cases, the error detection scheme provides a method or means to detect such errors and drop the packet. Corresponding interconnect system with error correction, encode and decode for such are also provided.

IPC: A61F2/915
Filed: 2000-04-17
Abstract: A laser cut stent for transluminal delivery has windows in its cylindrical wall, the windows giving the stent enhance flexibility during delivery along  said lumen. A method of making such a stent involves removing from the wall of a tube enough material to leave the tube wall penetrated in a multiplicity o f separate cut lines, in a pattern which permits the tube to expand. The tube is then expanded and then a plurality of tube wall scrap portions are removed from the tube wall between adjacent cut lines, thereby to introduce a plurality of spacings between adjacent stenting zones of the tube wall surface, these remaining after compression of the tube to a configuration to  allow it to be advanced along a tortuous bodily lumen. Advantageously, the material of the tube is a shape memory alloy and the tube is for a self- expanding stent.

Abstract: A weldment connector for use with castable concrete slabs, each of the slabs including a length, width and depth and having at least one opposing and extending edge. The weldment connector has a substantially elongated and planar shaped front face and first and second legs which are both integrally formed with and extend from opposite end locations of the front face. The legs further extend in a combined axial and rotationally offset fashion relative the front face and so that, upon being embedded within a first selected slab of concrete with front face extending in exposed fashion along its extending edge, the construction of the legs exhibits greater resistance to cracking. In use, a second weldment connector is likewise embedded within a second selected slab of concrete in similar fashion and so that its corresponding front face extends along an opposing extending edge, in proximate fashion relative to the front face of the first weldment connector. A conventional weldment, such as is provided by an electric weld gun, secures together the front faces of the first and second connectors. In use, the weldment connectors act to redistribute, within the interior body of each concrete slab, load forces applied along its common seamed edge.
