Abstract: An electric drive system, in particular for a rail vehicle, includes an electric energy accumulator and an electrochemical energy accumulator, connected in parallel. According to at least one embodiment of the invention, a component, e.g., a diode with a transmission direction facing away from the electrochemical energy accumulator, is situated in a connecting line between the electric energy accumulator and the electrochemical energy accumulator.

Abstract: An energy storage system for a track-guided vehicle includes at least one electrical energy storage device and at least one electrochemical energy storage device connected through at least one converter to a supply line and to a drive unit for the vehicle. Individual phases of said at least one converter can be operated as independent direct-current controllers for independent charging and discharging of different energy storage devices.

Abstract: A device is disclosed for cooling an energy accumulator in a rail vehicle. According to at least one embodiment of the invention, the energy accumulator has a direct thermal connection to an evaporator and the evaporator and a condenser form part of a circuit of a refrigerator.

Abstract: A method is disclosed for cooling an energy accumulator in a rail vehicle, using air. According to at least one embodiment of the invention, the air is fed to the energy accumulator directly from an already cooled or air-conditioned area of the rail vehicle. This occurs in particular when the temperature of the area is lower than the external temperature.

Abstract: The invention relates to a display pullout for electronics or information technology cabinets, which can be effectively utilized in modern communication technology environments. The display pullout has at least one display and at least one input interface, which can be transferred from a space-saving storage position in the cabinet into a working position for operating the input interface and/or data output on the display. A computing unit having at least one processor, a volatile memory and a device for the graphical output of data on the flat display is provided in the rear region of the display pullout, and is configured for the determination and processing of information and/or data of a majority of the input via the input interface and for the output of the information and/or data determined on the display for communication with at least one server.

Abstract: The present application relates to a process for preparing cold-pressed grape seed oil, and to food, food supplements, food additives, animal food, animal food supplements, medicaments and cosmetics comprising the cold-pressed grape seed oil prepared by said process, and to the enrichment of various media with active substances, especially cyclic polyphenols, from the meal of the crushed seeds obtained in the process.

Abstract: The invention provides a printing ink composition comprising a pigment or pigment preparation, a thermoplastic resin, water, a water-soluble solvent, and, as inhibitor for preventing the foaming of a foamable material containing a blowing agent, an azole of the formula ##STR1## wherein A is a benzene or naphthalene radical, X is a nitrogen atom or the ##STR2## group, wherein R is a hydrogen atom or an alkyl group of 1 to 4 carbon atoms, R.sub.1 is an alkyl or alkenyl group, each of 1 to 20 carbon atoms, a hydroxyalkyl group of 2 to 20 carbon atoms, an alkoxyalkyl or cyanoalkyl group, each of 3 to 20 carbon atoms, a cycloalkyl group of 5 to 12 carbon atoms, or a phenalkyl group of 7 to 9 carbon atoms, R.sub.2 has the same meaning as R.sub.1 and can in addition be hydrogen, or R.sub.1 and R.sub.2, together with the nitrogen atom to which they are attached, form a heterocyclic ring.
