Abstract: A blade for a fan that can be arranged on a rotor shaft of a rotor of a rotating electric machine, in particular a generator, wherein the blade is at least partially formed from a fiber composite material that has a polymer matrix with mineral fibers embedded therein. A method for producing a blade for a fan arrangeable on a rotor shaft of a rotor of a rotating electrical machine, in particular a generator, wherein the blade is produced using an injection molding method, and wherein a fiber composite material of a polymer matrix with mineral fibers embedded therein is used as injection molding material.

Abstract: The invention relates to a positioning device for a laboratory apparatus for distributing fluid samples comprising: a base member, a first part at which a transport device can be arranged, the first part arranged at the base member for carrying out at least one operation movement, a second part arranged at the base member at which a sample container holder can be arranged, the first and second parts movable relative to one another for carrying out positioning movements and adapted to be arranged in relative positions, a coupling device for coupling the operation and positioning movements, set up such that the relative positions of the first and second parts can be stepwise changed by way of repeatedly performing the operation movement; and to a method for automatically positioning a first part relative to a second part and to a laboratory apparatus comprising such a positioning device.
