Abstract: A holding device for battery cells for constructing a high-voltage storage module which can be used for electrically operated motor vehicles is provided. The battery cells, in a P assembly (i.e. interconnected in parallel), are provided with a minimally thin thermal insulating layer and, encased in this way, are brought into direct contact with each other in a self-holding arrangement. The intermediate spaces between the battery cells, which battery cells have been provided with the insulating layer and, encased in this way, have been brought into contact with each other, are preferably filled with a thermally conductive potting compound. The thermally conductive potting compound can additionally have high electrical conductivity and thus, in addition to the heat transfer, can also establish the contacting of the anodes in the P assembly if the anodes are also encased by the potting compound.

Abstract: The invention relates to a membrane valve, for transfer of biological and pharmaceutical products in particular, which an be opened pneumatically. By introducing air through an inlet opening (19) said air therein through a hollow spindle (4, 13, 23) reaches the space below a piston (12), lifts the latter and thus opens said valve. By providing for a hollow spindle (4, 13, 23) the supply of air can be effected in the drive portion. Interfering conducts and devices outside of said valve can thus be avoided, this permitting a more compact, room-saving construction of said valve as well as a simplified maintenance and cleaning of said valve.

Abstract: A method of mounting an electronic power component to a cooling element includes finishing at least a bonding area of the cooling element with a finish for use during soldering, forming an indentation in the bonding area of the cooling element, placing adhesive in the indentation, attaching the power component to the cooling element using the adhesive, and thereafter soldering the power component to the cooling element. The finishing melts during soldering and the adhesive prevents shifting of the power component on the cooling element during soldering. Alternatively, the power component is attached to a printed circuit board by adhesive bonding prior to soldering.
