Publication number: 20200407331Abstract: The present invention describes novel chelators (multidentate ligands) and precompounds for complexation of radiometals and non-radioactive counterparts, for use in radiopharmacy. The invention includes a process and a kit involving such chelators. Active moieties directing to a pharmaceutical target (such as peptides or proteins) can be attached to the chelator very easily via the so called “click-chemistry” forming a triazole-ring moiety. The aromatic triazole-nitrogen itself acts as a new and “soft” nucleophilic site enabling for complexation of various radiometals or non-radioactive counterparts. The chelators are capable of fast complexation at low temperature.Type: ApplicationFiled: February 28, 2019Publication date: December 31, 2020Applicant: HELMHOLTZ-ZENTRUM DRESDEN - ROSSENDORF E.V.Inventors: Hans-Jürgen PIETZSCH, Martin WALTHER

Patent number: 9291278Abstract: A housing of a pressure-loaded component includes a pressure-loaded channel system which corresponds to the tensile and/or compressive strength properties of the housing material and to the tensile and/or compressive stresses in the housing material during operation of the pressure-loaded component. The housing also includes a channel rounded profile configured to be adapted to include a formed asymmetry. The formed asymmetry is configured to reduce tensile stresses occurring in operation and thus increase the load carrying capacity of the housing as a whole.Type: GrantFiled: February 1, 2011Date of Patent: March 22, 2016Assignee: Robert Bosch GmbHInventors: Klemens Strauss, Frank Weis, Martin Walther

Patent number: 7481827Abstract: A Linking Transconnector is disclosed for coupling a first longitudinal spinal rod to a second longitudinal spinal rod. The Linking Transconnector generally includes a pair of hook engaging members for engaging the longitudinal spinal rods, a lateral rod for spanning a distance between the hook engaging members, and a locking element which interconnects the hook engaging members with the lateral rod. The locking element being configured to allow for multiple degrees of adjustment to permit the Linking Transconnector to accommodate for varying spinal rod alignments. The locking element also permits the location of the lateral rod to be fixed relative to the hook engaging members once the desired position of the lateral rod with respect to the longitudinal spinal rods has been achieved. The locking element may also be able to fix the position of the lateral rod with respect to the hook engaging members by a force applied to the locking element.Type: GrantFiled: October 9, 2003Date of Patent: January 27, 2009Assignee: Synthes (U.S.A.)Inventors: Christopher J.

Patent number: 6025013Abstract: A PCVD process for producing coating layers of uniform thickness of domed substrates. The substrate surface to be coated is arranged in relation to the gas passage surface of a gas showerhead. In order to determine the appropriate processing parameters, in a first series of tests for one type of substrate to be coated, the size of the gas passage surfaces and the gas mass flows through the gas passage surfaces are kept constant, while the intervals between plasma impulses are gradually modified, from an initial value t.sub.A until an optimum value t.sub.eff is determined, and until the uniformity of the thickness profile of the layers generated on the substrate may no longer be improved. If required, during a second series of tests, the value t.sub.eff may be kept constant, while the thickness profile of the layers is further modified by further optimizing the local parameters and/or the gas mass flows until layer uniformity may no longer be improved.Type: GrantFiled: January 22, 1997Date of Patent: February 15, 2000Assignee: Schott GlaswerkeInventors: Martin Heming, Ulrich Lange, Roland Langfeld, Wolfgang Mohl, Jurgen Otto, Volker Paquet, Johannes Segner, Martin Walther
