Abstract:
The present invention discloses improved air embossing systems, improved air lances, and improved methods of air embossing fabrics, which are able to produce an unprecedented level of fine detail, crisp transition between unembossed and embossed regions, and a high degree of uniformity across the width of an embossed fabric, when compared to the performance of typical, conventional air embossing systems. The air embossing systems provided by the invention can utilize air lances for directing a stream of air onto the embossable surface of a fabric that have at least one nozzle having a characteristic orifice dimension substantially less than that of conventional air lance nozzles. The disclosed air embossing systems can also include air lances having nozzles positioned in close proximity to the embossable surface of a fabric being embossed, substantially closer than is typical for air lances employed in conventional air embossing systems. Air lances provided according to the invention can also include one or more nozzles having a characteristic orifice dimension that is substantially less than a characteristic length of the nozzles. Certain air lances provided according to the invention can also include one or more nozzles in the shape of an elongated slit oriented, with respect to the air lance, so as to be positioned across essentially the entire width of a fabric being embossed with the air lance. The invention also provides air lances for use for embossing fabrics that can include a nozzle-forming component that can be separable from the main body of the air lance and that enables the nozzle(s) of the air lance to be positioned within close proximity to the fabric, when the air lance is in operation, and that also can act to redirect air flowing within the air lance so that it is emitted from the nozzle(s) such that a substantial fraction of the air stream is directed essentially perpendicular to the surface of the fabric being embossed. Yet other air lances disclosed include therein one or more baffles or air redirecting elements, which serve to deflect air flowing within the air lance so that it passes through the nozzle(s) of the air lance and is directed onto the embossable surface of the fabric at an angle that is substantially greater, with respect to the longitudinal axis of the air lance, than the angle of an air stream emitted from a nozzle of an essentially equivalent air lance, except excluding the air redirecting element or baffle. Some of the air lances described according to the invention can include a combination of several or all of the above described features.
Abstract:
A scalable policy-based Web Services security architecture that incorporates a combination of authentication with service discovery, evaluation of access policies, and capturing the result of this process in a signed, security token, thus, allowing efficient processing for each service request in a secure manner. A method for securing a Web Service comprises discovering the Web Service in response to a service request and determining an access policy for the Web Service separately from the actual service based on the service request.
Abstract:
Vaccines and methods against M. haemolytica infections in cattle. The vaccine compositions include a recombinant outer membrane protein of M. haemolytica designated PlpE and/or subunits thereof, alone or in combination with other antigenic components, and a carrier or diluent. The methods involve administering an effective immunizing amount of the vaccines to susceptible bovine.

Air embossing systems, air lances, and methods of air embossing fabrics produce an unprecedented level of fine detail, crisp transition between unembossed and embossed regions, and a high degree of uniformity across the width of an embossed fabric. The air embossing systems can utilize air lances for directing a stream of air onto the embossable surface of a fabric that have at least one nozzle having a characteristic orifice dimension substantially less than that of conventional air lance nozzles, and also substantially less than a characteristic length of the nozzle. Air lances can also include one or more nozzles in the shape of an elongated slit oriented so as to be positioned across essentially the entire width of a fabric being embossed. Air lances for embossing fabrics can include a nozzle-forming component that can be separable from the main body of the air lance and that enables the nozzle(s) of the air lance to be positioned within close proximity to the fabric, when the air lance is in operation, and that also can act to redirect air flowing within the air lance so that it is emitted from the nozzle(s) such that a substantial fraction of the air stream is directed essentially perpendicular to the surface of the fabric being embossed.

Abstract:
Air embossing systems, air lances and methods of air embossing fabrics produce fine detail, crisp transition between unembossed and embossed regions, and a high degree of uniformity across the width of an embossed fabric. The air embossing systems utilize air lances (210) for directing a stream of air onto the embossable surface (113) of a fabric (111) that have at least one nozzle (216) having an orifice dimension substantially less than that of conventional nozzles. The air embossing systems can also include air lance nozzles positioned in proximity to the embossable surface, nozzles with an orifice dimension that is substantially less than the nozzle length, nozzles in the shape of an elongated slit oriental across essentially the entire width of the fabric, air lances including a nozzle-forming component (214) separable from the main body (212) of the air lance to enable the nozzle to be positioned within close proximity to the fabric and to redirect air to be emitted such that a substantial fracti n of the air stream is directed perpendicular to the fabric surface, and air lances including baffles r air redirecting elements (340) which deflect air to pass through the nozzle and nt the fabric surface at an increased angle, relative to the air lance longitudinal axis.
Abstract:
The present invention provides methods and compositions that enable tagging and amplification of targeted RNA molecules. A targeted RNA molecule is any non-polyadenylated RNA molecule including, for example, miRNA, siRNA, rRNA, tRNA, synthetic RNA, or non-polyadenylated mRNA such as mRNA from bacteria. In certain aspects, the invention provides methods and compositions for the genome-wide expression analysis of bacterial genes. Significantly, the methods enable genome-wide expression analysis in circumstances where bacterial numbers were previously too low to purify adequate amounts of RNA for DNA microarray analysis or other applications. Such methods are particularly useful for the study of bacterial gene expression during host-cell infection. The invention also provides kits for tagging and amplifying targeted RNA molecules.
