Patent number: 5984562Abstract: An arrangement for fixing a tubular element, such as a shaft, that is provided with a bore and a flange in position with respect to plate element involves the use of a ball that pressed into the bore in the tubular element. To achieve a simple fixation that is secure in both axial directions, the plate element is fixed on one side by the flange of the tubular element and on the other side by the bulge that is created through insertion of the ball into the bore in the tubular element. The ball has a greater diameter than that of the bore in the tubular element so that insertion of the ball into the bore causes the tubular element to become enlarged, thus forming the bulge.Type: GrantFiled: September 12, 1997Date of Patent: November 16, 1999Assignee: SKF GmbHInventors: Manfred Brandenstein, Wolfgang Friedrich, Roland Haas, Roland Harich, Gerhard Herrmann, Josef Stork

Patent number: 5716845Abstract: This invention is directed to construction of recombinant plasmids that contain the Epstein-Barr virus ("EBV") genetic information involved in the immortalization of human lymphocytes, but that lack one or more genes implicated in EBV lytic replication. The recombinant plasmids have the advantage of being able to immortalize human lymphocytes, while being incapable of generating infectious EBV particles. The invention also provides human lymphocytes that have been successfully infected and immortalized by the recombinant plasmids. These human lymphocyte clones can be used as cellular factories to produce desired proteins and as delivery vehicles for gene therapy. Additionally, the invention establishes a method by which desired proteins can be produced in immortalized cellular factories, without generating infectious EBV particles. These proteins can be the normal cellular products of immortalized human lymphocytes, or they can be proteins encoded by foreign genes, which have been cloned into the lymphocytes.Type: GrantFiled: July 20, 1995Date of Patent: February 10, 1998Assignee: Wisconsin Alumni Research FoundationInventors: William Maxwell Sugden, Wolfgang Friedrich Hammerschmidt
