Abstract: A base HVAC device block (10) comprising a housing (11); an HVAC functional device (M/S); an extension interface (16A); an external electrical interface (18) for the transmission of electrical power and data signal(s); and an electronic circuit (12) connected with the HVAC functional device (M/S). In a first configuration, the base HVAC device block (10) is configured to connect the external electrical interface (18) with the electronic circuit (12) for transmission of data signal(s) and thereby provide HVAC functionality(s) of a first category. In a second configuration, the base HVAC device block (10) is configured to route the transmission of data signal(s) through an add-on electronic circuit (22) of an add-on HVAC device block (20) attached to the base HVAC device block (10) via an add-on interface (26B) of the add-on HVAC device block (20) to thereby provide HVAC functionality(s) of a second category.

Abstract: The invention relates to a rail vehicle (1) comprising a first passenger car and a powerpack (2) having a longitudinal axis, the powerpack (2) and the passenger car being coupled together. The powerpack (2) comprises at least one fuel cell (20) and at least one fuel tank (21) having a fuel tank valve (33). The powerpack (2) is mounted on at least one bogie. The rail vehicle (1) comprises at least one driven bogie which can be supplied with electrical energy from the fuel cell (20).

Abstract: An apparatus for cutting up biological sample material, including a sample container, a rotary drive device separate from the sample container, and a shaft rotatably arranged in the sample container, wherein the shaft has a laterally projecting cutting device in the region of a working end and has a coupling piece in the region of a coupling end, said coupling piece being accessible from outside and being designed for coupling engagement with a coupling counterpart of the rotary drive device, wherein the shaft (14) is arranged with lateral guidance and in an axially displaceable manner in the sample container (10), the coupling piece (19) and the coupling counterpart (21) are designed for producing coupling engagement which is positive-locking in the direction of rotation (23) and permits an axial displacement, and the cutting device (16) is designed in a propeller shape in such a way that, during rotation of the shaft (14) in the working direction, it exerts a propulsive force on the latter in the direction
