Abstract: The present invention relates to a bispecific single chain antibody molecule comprising a first binding domain consisting of one antibody variable domain capable of binding to an epitope of the human and non-chimpanzee primate CD3 epsilon chain, wherein the epitope is part of an amino acid sequence comprised in the group consisting of SEQ ID NOs. 2, 4, 6, and 8, and a second binding domain capable of binding to an epitope of a human and a non-chimpanzee primate tumor target antigen. The invention further relates to a bispecific single chain antibody molecule comprising a first binding domain capable of binding to an epitope of human and non-chimpanzee primate CD3? (epsilon) chain, wherein the epitope is part of an amino acid sequence comprised in the group consisting of SEQ ID NOs. 2, 4, 6, and 8, and a second binding domain consisting of one antibody variable domain capable of binding to an epitope of a human and a non-chimpanzee primate tumor target antigen.

Abstract: A profiled blade for a fan impeller comprising a profiled body produced from at least one bent sheet metal strip. The profiled body includes a profile top part with a convex curvature, a profile bottom part located at a distance from the profile top part, and first and second profile noses. Each of the profile noses has a convex curvature and joins the profile top part to the profile bottom part at ends of the profiled body. The profile top part and/or the profile bottom part is divided into at least first and second profile sections. The first profile section is joined to the first profile nose and the second profile section is joined to the second profile nose. A first free end region of the first profile section is joined to a second free end region of the second profile section by adhesive force.

Abstract: Profiled blade for a fan wheel, with a profile body produced from at least one curved metal strip, whereby adjacent end zones of the at least one metal strip are connected to each other in an adhesively bonded and/or form-fit manner wherein a second end zone at a distance from a second end zone edge is equipped with at least one embossed area for forming a contact surface enabling a first end zone to, at least in sections, be brought into contact with it.
