  • Patent number: 10773586
    Abstract: A motor vehicle with a cooling system, comprising an electric traction motor, an ambient heat exchanger, a bypass to the ambient heat exchanger, a traction battery, a coolant heater, a coolant-refrigerant heat exchanger of an air conditioner, a first coolant pump, and a second coolant pump that are directly or indirectly connected or connectable to one another via coolant lines and a distribution system, characterized in that, in a first functional position of the distribution system, coolant is conveyable, by means of the first coolant pump, in a first coolant circuit that includes the traction motor, the bypass to the ambient heat exchanger, and the coolant-refrigerant heat exchanger, and coolant is conveyable, by means of the second coolant pump, in a second coolant circuit, separate from the first coolant circuit, that includes the traction battery and the coolant heater, and in a second functional position of the distribution system, coolant is conveyable, by means of the first coolant pump, in a third c

  • Patent number: 9140053
    Abstract: Using the lowest possible amount of resources, a system is to be provided with a structural element (1), which system allows the characteristics of a vacuum to be used in the construction sector in a particularly simple manner. In particular, with a substantial freedom from thermal bridges, it is possible to also subsequently insulate a building envelope, for example, in situ at the lowest possible cost and this insulation is to be flexibly adaptable to changes of the building envelope. For this purpose, the structural element (1) comprises two cover layers (2) arranged substantially parallel to one another and a closed frame structure (4) which is formed integrally with the cover layers (2) and is arranged between said cover layers (2) such that a gastight cavity (6) is formed, said cavity (6) containing a vacuum.

  • Patent number: 9109364
    Abstract: A method for fastening a cover plate (6) to a frame structure (1) formed on the cover plate (6) is to easily and rapidly allow the erection of faces that are stable and durable in the long term and simultaneously, in the case of vacuum insulating panels, allow particularly good preservation of the vacuum in the panels. For this purpose, the frame structure (1) comprises a cavity (12), a number of channels (2) connecting the cavity (12) to the surface (4) and an opening (8) to connect a vacuum pump (10), the vacuum pump (10) being connected to the opening (8) and put into operation, the cover plate (6) being arranged on the surface (4) above the channels (2), and the cover plate (6) being fixed to the surface (4).

  • Patent number: 5296237
    Abstract: A water-soluble metallocene-complex composition which can be used as a cytostatic is described, which can be obtained by mixing a metallocene complex, a polyol, water and optionally additives, whereby glycols, sugar alcohols and carbohydrates are primarily used as the polyols.
