Abstract: A battery module for an electric vehicle, includes a plurality of battery cells and at least one electrical resistance element arranged between the battery cells for heating the battery cells as needed. The electrical resistance element includes a polymer composition having a positive temperature coefficient.

Abstract: A vertical strip storage system has a support structure and a storage car connected to the support structure by cables in the fashion of a pulley block so as to be lifted and lowered relative to the support structure. The storage car is provided with a counterweight and with deflection pulleys which deflect and guide an incoming and/or outgoing strip in cooperation with stationary deflection pulleys on the ground. The support structure is a free-standing column without lateral supports and the storage car is a salient vehicle running on the outer surface of the column, wherein the column has an interior and the counterweight is guided in the interior of the column.

Abstract: A bulk material dosing or feeder device has at least one upright post mounted to a base and carrying a horizontal head section. A supply hopper is supported by the head section. Modular units such as a stirrer, a weigher or feeder or the like are vertically aligned, vertically below the hopper. At least one, preferably each modular unit is mounted on a respective swivel arm. The swivel arm is journalled to the upright post whereby the modular unit may be tilted into an operative position below the hopper or into an out position for easy access to and exchange of the modular units.
