Publication number: 20100297468Abstract: The invention concerns a method to create fusion-integrated joints of workpieces, in which a workpiece area formed on a workpiece made from a TiAl alloy and a workpiece area formed on another workpiece made from a TiAl alloy or a different high temperature material are joined in a joint area using a joining additive, where the joining additive contains at least one of the elements gallium and indium. The invention also concerns a method to create a material deposit on a workpiece, in which a deposit material is applied to a workpiece area made from a TiAl alloy, where a fusion-integrated joint is produced between the deposit material and the workpiece area, where the deposit material contains at least one of the elements gallium and indium and a filler material.Type: ApplicationFiled: October 10, 2008Publication date: November 25, 2010Applicant: ACCESS E.V.Inventors: Ulrike Hecht, Victor Vituesevych, Christian Holzschuh

Patent number: 6994518Abstract: A pre-whirl generating apparatus (26) is provided that employs deformable air deflecting vanes (46) adjacent the inlet (18) of a radial air compressor (12-22), which vanes (46) can be mechanically deformed to generate positive, neutral, or negative pre-whirl flow to the compressor. A minimum number of parts are used to position one or more thin, deformable vanes (46) in the intake channel (34) leading to the compressor inlet (18). In their undeformed position, the vanes (46) do not deflect the incoming air, thereby causing little or no flow restriction. To achieve the desired positive or negative pre-whirl of flow to the compressor (12-22), the trailing edge (62) of the vanes (46) are deflected transverse to the direction of flow in the channel (34) in either the positive or negative direction.Type: GrantFiled: November 13, 2003Date of Patent: February 7, 2006Assignee: BorgWarner Inc.Inventors: Volker Simon, Mathias Weber, Christian Holzschuh
