Abstract: The present invention generally relates to novel bispecific antigen binding molecules for T cell activation and re-direction to specific target cells. In addition, the present invention relates to polynucleotides encoding such bispecific antigen binding molecules, and vectors and host cells comprising such polynucleotides. The invention further relates to methods for producing the bispecific antigen binding molecules of the invention, and to methods of using these bispecific antigen binding molecules in the treatment of disease.

Abstract: The present invention concerns a vent valve for acid batteries comprising a substantially cylindrical plug portion (28) which is designed for being brought into engagement with a cell opening of the acid battery (1) and which has at least one passage opening communicating the cell interior of the acid battery with the ambient atmosphere, wherein provided in the passage opening is a valve arrangement (29) having an inlet communicating with the cell interior and an outlet connected to the ambient atmosphere. In order to provide a vent valve for an acid battery, in particular an acid battery with fixed electrolyte, which is simple and inexpensive to produce and which affords improved protection against the escape of battery acid, it is proposed in accordance with the invention that at least one turbulence chamber (30) follows the passage opening of the plug portion (28) in the direction of the cell interior and a gas-permeable filter unit (31, 31?) follows the turbulence chamber (30).
