Abstract: Methods for syntheses of polyvalent carbohydrate molecules by glycosylations of partially protected polysaccharides with a single glycosylating agent or a mixture of glycosylating agents (i.e., a combinatorial library) are disclosed. An alternate method utilizes a glycoside, the aglycon of which carries a halogen which can be under strong alkaline conditions linked with a partially protected polysaccharide by an ether linkage. The product of the latter reaction can be subjected to further glycosylation with a single glycosylating agent or a mixture of such agents (=library). The novel resulting polyvalent carbohydrate molecules may be used as antiinfective agents (antibacterial, antiparasital), both for prevention and treatment of diseases, and as agents either for preventing the formation of, or disrupting, biofilms.

Title: Hazard analysis critical control point (haccp) can opener
Inventor: BELLIS MARLA J
IPC: B67B7/46
Filed: 1999-11-19
Granted: 2008-12-30
Abstract: Disclosed is a safe and reliable method and apparatus for opening cylindrical metallic containers which cuts into the side of the cylindrical body of the can below the upper annular rim. The device of the present invention employs a specially adapted, angularly-positioned, tapered rotatable blade for performing the cutting operation. The use of a rotatable blade results in a clean non-jagged cut around the circumference of the container. The use of a rotatable, tapered blade to cut below the annular rim or seam of the container results in an inwardly-bent edge on the newly-cut lid having no sharp edges. This facilitates easy and worry free removal of the lid. In use, a can is placed in the device such that the knurled edge of an upper disc rests upon the top of the can. The rotatable side cutting blade is then moved such that it pierces the side of the can, just below the lip seal. The side cutting blade is locked into place, and the upper disc is rotated, thereby rotating the can. As this takes place, the rotatable side cutting blade cuts the top off the can.

Abstract: A free-size cap with a size adjusting band is disclosed.      In the cap, six gores, integrated into a crown, are made of a stretchable woven fabric, with a weft directional elongation of the gores being higher than a warp directional elongation of the gores. A sweat band is attached along a lower edge of the integrated gores. The sweat band is made of a stretchable woven fabric, with a weft directional elongation of the sweat band being higher than the weft directional elongation of the gores. The warp directional elongation of the gores is 25% ~ 2%, and the weft directional elongation of the gores is 50% ~ 5%. The weft directional elongation of the sweat band is 65% ~ 5%. The free-size cap is thus primarily and manually adjusted in size by its size adjusting band and is finely and automatically adjusted in size by the elasticity of the stretchable woven fabric of both the crown and the sweat band.      The cap thus allows a user to feel comfortable while wearing the cap. The cap is made of stretchable woven fabric designed to have a high elasticity in both wefts and warps, thus being prevented from easily wrinkling in a vertical or horizontal direction while having a desired automorphism.

Title: Incorporation of smoke-modifying agents in smoking material rods

Granted: 2005-10-11
Abstract: A method of incorporating fibriform smoke-modifying material in smoking material rod, wherein fibriform smoke-modifying material is fed longitudinally thereof to a rod making machine (1). The longitudinal feed path in the machine is in a travel direction of the smoking material deposition run of the suction band (3) of the machine. The fibriform material (13) is either constrained by guide means (15) in the machine to follow a feed path spaced from the run (31) of the suction band against the suction force towards the run or the feed path of the fibriform smoke-modifying material is caused to ascend toward the deposition run under the influence of the suction force towards the run, until at a predetermined distance along the deposition run the fibrifonn material becomes supported and is subsequently maintained at a predetermined distance from the run by particulate smoking material (20) deposited on the run. Thereafter further smoking material (20') is deposited on the deposition run.

Title: Transmitter and method for transmitting a pattern in a multicarrier modulation transmission system
Inventor: ASLANIS JAMES T
IPC: H04L7/08
Filed: 1995-07-11
Granted: 2003-01-14
Abstract: A discrete multitone modulation transmission system is described in which frame synchronization is monitored at the receiver by correlating frequency domain complex amplitudes of a synchronizing frame with a stored synchronizing pattern. If the correlation result falls below a threshold, indicating a loss of frame synchronization, a plurality of correlations are performed, in each case using the stored complex amplitudes of the synchronizing frame multiplied by a respective complex value representing a respective complex denotation corresponding to a respective possible time shift of the synchronizing frame. The best correlation result, if it exceeds another threshold, indicates a time shift for restoring frame synchronization, this being possible before the next synchronizing frame is received.

Title: Flap mechanism
Inventor: JESSBERGER THOMAS
IPC: F02D9/10
Filed: 1999-10-14
Granted: 2007-12-18
Abstract: The invention relates to a flap mechanism which comprises means for compensating tolerances and the shrinkage behavior of the flap (11). These means exist primarily by the provision of a flap edge (14) which is connected by injection molding after the injection molded flap (11) has cooled, and thus reduces the gap between the flap (11) and the flap frame (10), said gap being produced by the shrinkage of the flap. In addition, the mounting of the shaft (12) in the frame (10) can be realized in an at least partially conical manner, whereby the shrinkage behavior of the flap shaft can be used, especially in an axial direction, in order to produce a mounting which is free of play. As a result, it is no longer necessary to use additional sealing elements on the mounting points of the flap. In addition, the flap is prevented from vibrating in the mounting which, in the worst case scenario, could lead to a destruction of the flap.
