Parasitic capacitances formed between bit lines to which signals are to be read out of memory cells and a signal transmission line arranged above them are to be reduced. A distribution system connected with the barrier fluid tank and with the fuel storage tank distributes barrier fluid about the outer periphery of the fuel contained within the storage tank in the event of a collision event, creating a boundary layer of more viscous fluid which inhibits exfiltration of the fuel from the fuel storage tank. The processing module is designed to detect an unauthorized access attempt by comparing the first and second power signals and to delete the key when the processing module is powered by the second power source. A support floor having support slips is mounted to the hydraulic cylinders at a fixed distance above the base. The device furthermore comprises press rams, which are guided in a moveable manner transversely to the longitudinal direction of the card flat bar and from both sides parallel to the clothing take-up surface of the card flat bar.
