Title: Apparatus for coating surfaces of bearings by vacuum deposition
Inventor: ANDLER GERD
IPC: C23C14/56
Filed: 1998-11-19
Abstract: Existing devices for vacuum coating substrates having different shapes, either in continuous or hatch facilities, are equipped in such a way that several coatings are applied after a coating process. The slide bearings are to be coated with several coats and the coating materials used and the conditions related thereto require the use of several coating techniques. This relates inter alia to conveyance parameters. Existing facilities fail to meet these requirements. According to the invention, such a device comprises several aligned processing chambers. Slide bearings which are held together by positive and non-positive fit in tempered carrier bodies are displaced through said chambers comprising pretreatment, atomization and evaporation chambers using a conveyance system adapted to this process. A tempering device for the carrier bodies is connected upstream from the coating track. Corresponding inlet and outlet channels enable air-to-air conveyance.

Title: Novel method for down-regulation of amyloid
Inventor: BIRK PETER
IPC: A61K35/76
Filed: 2001-02-19
Abstract: Disclosed are novel methods for combatting diseases characterized by deposition of amyloid. The methods generally rely on immunization against amyloidogenic proteins (proteins contributing to formation of amyloid) such as beta amyloid (A²). Immunization is preferably effected by administration of analogues of autologous amyloidogenic polypeptides, said analogues being capable of inducing antibody production against the autologous amyloidogenic polypeptides. Especially preferred as an immunogen is autologous A² which has been modified by introduction of one single or a few foreign, immunodominant and promiscuous T-cell epitopes while substantially preserving the majority of A²'s B-cell epitopes. Also disclosed are nucleic acid vaccination against amyloidogenic polypeptides and vaccination using live vaccines as well as methods and means useful for the vaccination. Such methods and means include methods for identification of useful immunogenic analogues of the amyloidogenic proteins, methods for the preparation of analogues and pharmaceutical formulations, as well as nucleic acid fragments, vectors, transformed cells, polypeptides and pharmaceutical formulations.
