Patents by Inventor Ralf Landgraf

Ralf Landgraf has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7811429
    Abstract: The invention relates to a target support assembly (1) comprising a support (2), on which a target lining is arranged. In order to simplify the production of the target lining or of the target support assembly and/or the placement of the target lining on the support, the target lining is formed by a target sleeve (4) that is slid onto the support (2). At least one clamping element (5) is placed, while actively clamping, between the support (2) and the target sleeve (4).

  • Patent number: 7314916
    Abstract: The disclosure provided herein identifies and characterizes the domain in HER3 receptor that interacts with heregulin ligand. Typical embodiments of the invention disclosed herein include HER3 variant polypeptides having amino acid sequences which differ from the native HER3 polypeptide sequence and which have altered affinities for heregulin. Also disclosed herein are methods and materials for identifying compounds that bind to the heregulin binding domain in HER3 as well as methods and materials for modulating the interaction between HER3 and heregulin.

  • Publication number: 20050040034
    Abstract: The invention relates to a method for applying one or several coats to a substrate in a device comprising a PVD/CVD coating chamber. One solid matter is physically transformed at least in part into a gaseous phase and is applied to the substrate in the gaseous phase. At least one additional compound and/or one additional metal is added to the gaseous phase in liquid or gaseous form, and the at least one additional compound and/or the at least one additional metal reacts with the surface of the substrate. The invention also relates to a coating that is produced according to said method.
