Granted: 2000-08-08
Abstract: The present invention provides an arrangement for shaping multiple sheets of heat softenable material which includes a shaping station and a conveying system to deliver a plurality of heat softened sheets into the shaping station. The shaping station includes an upper vacuum mold having a plurality of downwardly facing sheet shaping surfaces each generally conforming to a desired shape of a sheet to be shaped and a plurality of stops positioned below the upper mold such that each of the sheets is aligned below a corresponding one of the upper mold sheet shaping surfaces when the sheet contacts selected stops. Lower molds are positioned below the upper mold sheet shaping surfaces to lift and press the aligned sheets against the upper mold sheet shaping surfaces to shape the sheets. A vacuum is drawn along the upper mold sheet shaping surfaces to secure the sheets to the upper mold and shape the sheets. The upper mold and shaped sheets are moved to a transfer station having a conveying surface generally corresponding to the desired shape of the sheets and the vacuum in the upper mold is released to deposit the shaped sheets from the upper mold onto the conveying surface. The stops are selectively movable within the shaping station to allow the sheets to be conveyed into the shaping station either in a side-by-side or serially aligned orientation and positioned below the upper vacuum mold.

Abstract: The present invention discloses that the normal melanogenic gene, gp75 gene, encodes a gene product, a 24 amino acid peptide of ORF3, which is processed to an antigenic cancer peptide recognized by T lymphocytes. The cancer peptide of the invention derived from ORF3 is recognized by cancer antigen specific T  lymphocytes as a tumor rejection antigen. The present invention relates to the identification of a second tumor antigen recognized by an HLA-A31 restricted CTL clone derived from the TIL586 cell line. This antigen derived from the TRP-2 protein tumor antigen and peptides thereof are capable of sensitizing target cells for lysis by a CTL clone at 1 nM peptide concentration. Modified peptides were also recognized by the CTL clone. The products of these genes are promising candidates for immunotherapeutic strategies for the treatment and diagnosis of patients with cancer.

Abstract: A directional tail transfer apparatus includes a tray that defines a longitudinal path line extending along the tray overwhich a paper tail to be threaded travels. The longitudinal path line of the tray is positioned adjacent a first section in a papermaking machine where the paper tail exits. The longitudinal path line is aligned with the initial path of movement of the paper tail. The tray has with one or more creases, which extend across the tray width and bisect the longitudinal path line to effect a natural change in direction of the longitudinal path line through the tray. At least one of the creases bisects the longitudinal path line at predetermined angles other than 90 degrees to provide a lateral displacement in the portion of the tray that follows this crease. This one crease allows the paper tail to fold along its width on an angle that is not perpendicular to the natural downstream path of travel of paper tail. As a result the paper tail changes direction to follow the tray along the longitudinal path line. The fold angle of the creases and lengths of the tray portions pre-selected to accurately deliver the paper tail to a threading nip. The tray further includes an air or gaseous flow source for directing an air-cushioning stream over the tray to pull or draw the paper tail over and along the tray surfaces. The tray is operable at all angles of installation, including an inverted position.

Abstract: To elucidate the molecular mechanisms of "gain of toxic function" of expanded polyglutamine stretches in CAG repeat expansion diseases, the inventorsestablished an expression system of full-length and truncated cDNAs for dentatorubral-pallidoluysian atrophy (DRPLA) and found that truncated DRPLA proteins containing the expanded polyglutamine stretch, but not the full-length protein, form peri- and intra-nuclear aggregates consisting of filaments and concomitant apoptosis. The apoptotic cell death was partially suppressed by transglutaminase inhibitors, cystamine and monodansyl cadaverine, raising the possibility of involvement of transglutaminase reaction. The results may providea potential basis for the development of therapeutic measures for CAG repeat expansion diseases.

Granted: 2001-05-15
Abstract: A method and apparatus for dynamically expanding an N drive RAID set to an M drive RAID set while maintaining data integrity, where the M drive RAID set includes one or more new drives. The method comprises the steps of identifying a destructive zone in the N drive RAID set including destructive zone data (400). Thereafter the destructive zone data is mirrored in the M drive RAID set by copying it to a free location in the N drive RAID set (408) and to a location in a new drive in the M drive RAID set (410). Finally, the N drive RAID set is expanded to an M drive RAID set (414). Data integrity is assured in the  N drive RAID set during migration by maintaining mirrored destructive zone data until the expansion step has completed migration of the destructive zone of the N drive RAID set (416).
