Abstract: A thermocycler having a base fitted with a temperature-controlled receiving segment for reaction vials is provided. The thermocycler further includes a top, which can be moved into its operational position above the receiving segment and a hermetic seal or wall configured in the top in its operational position that extends between the top and the base thereby sealing both the top and the base.

Abstract: A thermocycler is provided that includes a temperature-controlled receiving segment for reaction vials, a top which can be assembled to said base and which in the assembled state may be moved from an open position into an operational position above the receiving segment, an optics configured in the top, where the optics and/or said receiving segment are configured with play in the top respectively the base, the play allowing a relative displacement between the optics and the receiving segment sufficient to adjust the optics relative to the receiving segment, and at least 2 positioning elements are present at each base and each top to allow reproducible alignment between the optics and the receiving segment in a mutually adjusted position.

Abstract: The invention provides a method of controlling a brushless electric motor, in which the motor is driven in a starting speed range (A) from standstill up to a lower threshold speed (N1) with an active control method and in an operating speed range (B) from the lower threshold speed (N1) up to an upper threshold speed (Nk) with a passive control method. The invention further provides an electric drive, with an electric motor and with an electronic control unit, in which the electric motor is controlled in accordance with a method according to any of the preceding claims, and also an electrohydraulic power-assisted steering with a hydraulic pump which is driven by such an electric drive.

Abstract: A method of producing hot-rolled strips and hot-rolled profiles from a continuous, continuously casted primary material, in which single slabs are transported from the buffer zone into a ferry which transports them by being transversely displaced from the casting line into the pitch line extending parallel to and spaced form the casting line, where it is stored in an accumulator furnace located parallel to an equalizing furnace and which is offset relative thereto, with the single slabs, upon request, being transported by a ferry from the accumulator furnace into the finishing train for finish-rolling the end product.

Abstract: The invention relates to a process and an apparatus for applying two or more colors of paint by applying a first paint to at least part of a substrate, followed by a second and, if desired, further different-colored paints to different parts of the substrate and hardening the applied coats of paint by baking, which comprises applying the second and if desired the further different-colored paints without interim baking of the first paint to the preselected different parts of the substrate using electrostatic atomization at stationary atomizer edges involving transport of the paint particles in an electric field and, after the first and subsequent paints have been applied, hardening all coats of paint together by baking.
