  • Patent number: 11938976
    Abstract: An arrangement for driving a locomotive has various energy-provision systems. The locomotive contains a main energy-provision system as the main system and a drive system. Energy provided by the main system is supplied to the drive system as drive power and is used by the drive system for moving the locomotive. A railroad car carries at least one additional energy-provision system as an auxiliary system. The auxiliary system is used in a manner which is temporally offset from the main system in order to supply drive power to the drive system. Components which can be used by both the main system and the at least one auxiliary system are implemented only once and are used jointly by both the main system and the auxiliary system. Components which are used exclusively by the auxiliary system are arranged on the railroad car.

  • Patent number: 10422609
    Abstract: A smoke munition or smoke grenade which can be fired from a launcher, for example a grenade launcher, and has at least one active charge for producing smoke as a protection for ships. To achieve the effect that the active charge of the smoke grenade can be delivered quickly and safely for the ship's crew and the active compound thereof can be converted completely into smoke even after hitting the water, the invention proposes providing the active charge with a floating aid, which can be deployed before the active charge hits the water and prevents the active charge from sinking and prevents the active compound that produces the smoke from becoming wet.

  • Publication number: 20190164421
    Abstract: A method for controlling air-conditioning components of a motor vehicle is described. A forecast vehicle temperature is ascertained. Further, a probable air-conditioning time for the motor vehicle is ascertained. Also, a setpoint temperature control state is prescribed. An air-conditioning requirement is ascertained on the basis of a comparison between the forecast vehicle temperature and the setpoint temperature control state. At least one air-conditioning component is actuated according to the air-conditioning requirement before the probable air-conditioning time with the control target of reaching the setpoint temperature control state at the beginning of the air-conditioning time.
