摘要： In order to provide a method for operating a motor-vehicle engine adapted to be driven by hydrogen gas, wherein hydrogen gas is compressed to an operational pressure level required for the high-pressure injection, which also enables a hydrogen engine to be operated at a storage pressure of the hydrogen gas conveyed in the motor vehicle which is below the operational pressure level required for the high-pressure injection, it is suggested that the hydrogen gas at a pressure below the operational pressure level be cooled to cryogenic temperatures and that the cold gas be compressed by means of a compressor operating at cryogenic temperatures and heated up again in the compressed state.

摘要： In order to improve a method for filling a cryotank with liquid hydrogen, in which thermal energy is introduced into the liquid hydrogen by the transfer of the liquid hydrogen to the cryotank, such that the amount of gas which results during filling of a cryotank and is carried away via the gas return line is reduced to as great an extent as possible, preferably to zero, it is suggested that for filling hydrogen be used at a pressure and a temperature corresponding to an undercooled state of the liquid hydrogen.

摘要： In order to improve a process for increasing the torque of an internal combustion engine burning a fuel by means of an oxidizing agent and comprising at least one cylinder and an induction system, in which the mass flow of the gaseous oxidizing agent into the cylinder or cylinders is increased, as well as an internal combustion engine such that the torque of the internal combustion engine is increased at any rotational speed to a greater extent than with known passive pressure-charging processes, it is suggested to make a charging mixture consisting of a charging fuel and the oxidizing agent available in the induction system and to ignite this cyclically in the induction system at such points of time that due to the expansion during the rapid combustion of the charging mixture an increase in pressure occurs at the intake port of at least one cylinder during its intake phase.

摘要： In order to develop a method for producing at least approximately ball-shaped metallic particles at least almost equal in diameter such that a greater yield of particles at least almost equal in diameter is achieved than in known methods, it is suggested that a continuous stream of liquid metal is acted on locally by compressional vibrations that thereby cross-sectional constrictions are formed in the stream at a distance from each other in longitudinal direction of the stream which lead to the dissection of the stream and that the segments of the dissected stream adopting a ball shape due to the surface tension of the liquid metal are cooled to solidify the liquid metal.

摘要： In a method for conveying a liquid at or in the proximity of its boiling temperature, in particular, liquid hydrogen, by means of a pump which draws the liquid from a storage container through a suction entrance port, in order to prevent undesired bubble formation in the suction region, it is proposed that the pressure in the storage container be increased for a short time during the suction phase of the pump above the equilibrium pressure of the liquid in the storage container. An apparatus for performing this method is also described.

摘要： A reciprocating pump for a cryogenic fluid includes a pump cylinder made of a material with low thermal expansivity, a piston displaceable in the pump cylinder, and self-lubricating piston rings made of polytetrafluorethylene held on the circumferential surface of the piston. The rings have a larger thermal expansivity than the pump cylinder. The arrangement allows optimum matching of piston rings and pump cylinder at cryogenic fluid pumping temperatures. The piston has a core made of a material with relatively large thermal expansivity which is surrounded by a spacer sleeve made of a material with a low coefficient of thermal expansion. The core protrudes on both sides from the spacer sleeve and has expanding regions increasing conically towards its free ends. The piston rings surround the core in the expanding regions and are supported against the end faces of spacer sleeve. The conical expanding regions bias the rings toward the cylinder at low temperatures to insure effective sealing.

摘要： An apparatus for magnetocaloric refrigeration, comprising a ferromagnetic terial arranged in a rotor and alternately entering and exiting from a stationary magnetic field when the rotor rotates, and also comprising a circuit for a working gas coming into successive heat exchange contact with a ferromagnetic material arranged outside the magnetic field and thereby cooled, a refrigeration load, a ferromagnetic material located within the magnetic field and thereby heated as well as an external negative heat source. In order to avoid problems with seals in such an apparatus at low temperatures, it is suggested that discrete members consisting of ferromagnetic material be arranged around the rotor circumference so as to be angularly offset, that two members be connected each time to form a pair by a flow path for the working gas, this flow path being arranged within the rotor and leading from an outer surface of the rotor via heat contact with one member of the pair into the center of the rotor and then via heat contact with the other member of the pair to an outer surface of the rotor again, that at least one stationary supply conduit ending in a sealed manner at the outer surface of the rotor and one stationary outlet conduit beginning in a sealed manner at the outer surface of the rotor be provided for the working gas, both conduits communicating with the flow path of one pair in a predetermined angular position of the rotor, that each outlet conduit be associated with a stationary magnetic field such that the member adjacent the outlet conduit is located within this stationary magnetic field and the other member of the pair outside the magnetic field in the predetermined angular position of the rotor, and that a cooling conduit be guided through a hollow bearing shaft of the rotor and have a refrigeration medium flowing through it, this refrigeration medium acting as refrigeration load and coming into heat contact with the working gas in the center of the rotor.
