Specified is an arrangement for supplying power to a motor vehicle which is equipped with an electric motor and in which there is arranged at least one rechargeable electric battery to which the electric motor is connected. The arrangement includes a stationary charging station which is equipped with an electric power source and to which an electric line having at least two mutually insulated electrical conductors is connected, a part of an electrical coupling for connecting to a complementary coupling part present on or in the motor vehicle being attached to the free ends of said electrical conductors, said coupling part being connected to the battery in an electrically conductive manner. The electric line is surrounded along its entire axial length by a thermally insulated and flexible tube made of metal which is closed all around and which, in addition to the line, encloses a cavity along its entire axial length. A flowable medium refrigerated to a temperature of at least 160 C. is contained in the space enclosed by the tube, and a thermally insulated storage tank containing a store of the refrigerated medium is arranged in the charging station, the tube being connected to said storage tank.

A modular fabrication tool for prefabricating insulation for a duct segment includes at least three interchangeable and detachably connected panels, each panel of the at least three panels corresponding to a respective side of the duct segment. Each panel includes at least one of a connecting bar extending beyond a periphery of the respective panel or a connecting track. A connecting bar of one panel is received by a connecting track of a neighboring panel when two neighboring panels are properly positioned, adjoined together, whereby a retaining pin of the tool is advanceable through aligned, respective apertures of the connecting track and the connecting bar received therein.

A hydrogen fuel coupling system may include a hydrogen fuel tank and a hydrogen fuel supply connector. The tank has a first connector, and a second connector disposed around the first connector. The second connector has a boil-off inlet port for receiving gaseous hydrogen from the tank. The hydrogen fuel supply connector may include a hydrogen fuel transfer line, a third connector for operably sealably connecting the transfer line to a first connector of the tank for supplying liquid hydrogen, and a shroud extending around the third connector and the transfer line defining a gap therebetween. A fourth connector operably sealably connects a first end of the shroud to a second connector of the tank. A second end of the shroud is operably sealably engageable with the transfer line. A boil-off vent is connected to the shroud for venting gas from the gap.

A joint structure connecting a first and second double pipe, includes a male bayonet at an end portion of one of the pipes, the male bayonet including a first flange; a female bayonet at an end portion of the other of the pipes, the female bayonet including a second flange fastened to the first; a first positioning member mounted on the first double pipe; a second positioning member mounted on the second double pipe, the second positioning member being positioned with respect to the first so that a center axis of the male bayonet and the female bayonet conform to each other; and a slide mechanism which supports the first positioning member so the first positioning member is slidable in an axial direction of the first double pipe or supports the second positioning member so the second positioning member is slidable in an axial direction of the second double pipe.

A double tube is provided, which can reliably prevent buckling and flattening of an inner tube even when bending is performed.

The present disclosure relates to the construction and use of feedlines in temperature-biased systems that include counter-biased hoses. The alignment and installation/uninstallation of the counter-biased hoses is enabled by a biasing tool with at least a first yoke having a first rotation point and a second rotation point, a second yoke having a third rotation point and a fourth rotation point, a first rod assembly connected to the first yoke at the first rotation point and connected to the second yoke at the fourth rotation point, and a second rod assembly connected to the first yoke at the second rotation point and connected to the second yoke at the third rotation point.

The proposed vacuum jacketed tube may deliver the high/low temperature fluid with less temperature-transfer, especially may delivery high/low temperature fluid through a flexible structure. The vacuum jacketed tube includes a tubular structure surrounding a pipe wherein the fluid is delivered therethrough. Also, the space between the tubular structure and the pipe may be vacuumed. Therefore, the heat transferred into and/or away the fluid may be minimized, especially if the tubular structure and the pipe is separated by at least one thermal insulator or is separated mutually. Moreover, the vacuum jacketed tube may be mechanically connected to the source/destination of the delivered fluid, even other vacuum jacketed tube, through the bellows and/or the rotary joint. Besides, the pipe may be surrounded by a Teflon bellows and the tubular structure may be surrounded by a steel bellows, so as to further reduce the heat transferred into/away the fluid delivered inside the pipe.

A rotary union that includes a heated ferrofluid seal is disclosed. The rotary union includes an inner rotating shaft, an intermediate rotating shaft and an outer rotating shaft. The inner rotating shaft is hollow to allow the flow of cryogenic fluid in one direction. The inner rotating shaft and the intermediate shaft are spaced apart to create a channel for the return of the cryogenic fluid. The intermediate rotating shaft is separated from the outer rotating shaft by a gap so as to reduce thermal conductivity. In this way, the temperature of the outer rotating shaft is greater than the temperature of the cryogenic fluid. A heated ferrofluid seal is disposed between the outer rotating shaft and the housing.

A sealed and thermally insulated tank for storage of a fluid, having a plurality of multilayer walls. A first of the walls has a secondary thermally insulating barrier including a first insulating panel along the intersection between the load-bearing structure of first wall and the load-bearing structure of an adjacent second wall. A second insulating panel is juxtaposed with the first insulating panel along one edge of the first panel opposing the second wall. The first wall has a secondary sealing membrane including a first corrugated metal sheet welded to a small metal plate of the first insulating panel; and a second corrugated metal sheet welded to the small metal plate of the second insulating panel. The first metal sheet and the second metal sheet are welded together via a joggled edge permitting the first and the second metal sheets to be lap welded to one another.
