Inventor: VOGT ERNST
IPC: B01D39/20
Filed: 1999-10-21
Abstract: Upper and lower mirror image die plates (64, 82) are resiliently supported and have predetermined displacement values for forming vortex generators (48, 50) and foldline crease channels (75, 100) without compressive deformation in a porous sintered metal fiber sheet material (14). Cutters (44) and ridges (73, 98) coupled to the upper and lower die plates (64, 82) form the respective vortex generators and channels. The sheet of so formed material is then placed in an apparatus for bending the sheet at the foldline channels (75, 100) to corrugate the sheet without deformation of the sheet material between the corrugation bends. Fingers align with and engage the channels. The fingers are on plates (128; 130; 166; 168) that are ramped closer together simultaneously while the fingers on two mirror image coplanar sets of plates displace toward each other as the sheet material is folded. Pins on a pair of rotating levers engage each of the finger plates of the two sets for relatively horizontally displacing the plates and corresponding fingers as they are ramped together vertically.

Abstract: The present invention provides means and methods for the generation and manufacturing of recombinant Ad vectors that are modified in E2B and/or E4 functions, preferably, said vectors comprise E1 and/or E2A deletions. For this purpose, the vector genome is modified in the respective promoter regions such that the promoter is only active in a suitable complementing cell line or only active following a certain signal in the case of an inducible promoter. The modified promoter is, on the other hand, inactive under normal conditions, and in normal mammalian and/or human cells. Hence, vectors that possess said modified promoter in the E2B and/or E4 region do not express the respective transcription region in mammalians and/or humans.
