Patent number: 11938976Abstract: 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.Type: GrantFiled: March 31, 2023Date of Patent: March 26, 2024Assignee: Siemens Mobility GmbHInventors: Bernhard Hoescheler, Stefan Lauer

Patent number: 8506294Abstract: The invention relates to a device for the automated production of dental workpieces. A blank is inserted in a substantially slab-shaped support of the device, said support being dimensioned such that the blank does not extend beyond it in any direction. The blank is linked with corresponding inner walls of a recess provided in the support only on two opposite faces while a gap is left between the other inner walls of the recess and the corresponding faces of the blank. The inventive design allows to avoid tensions and microcracks of the blank material thereby caused. The gaps further make the blank directly accessible for a lateral working by the milling tool.Type: GrantFiled: December 23, 2002Date of Patent: August 13, 2013Assignee: 3M Innovative Properties CompanyInventors: Olaf Althoff, Daniel Suttor, Stefan Hoescheler, Martin Beuschel
