摘要： The present invention relates to a power supply system for underwater vehicles, in particular to a power supply system for autonomous underwater vehicles, to underwater vehicles equipped with such power supply systems and to a method of operating an underwater vehicle. The power supply system for underwater vehicles comprises a hydrogen fuel cell, which on the one hand is in fluid contact with a metal hydride storage tank, and on the other hand, with a membrane module that is capable of extracting dissolved oxygen from water. By combining the above mentioned components, the energy necessary to support the AUV operation and the operation of its sensors can be provided, replacing in an efficient and sustainable way the currently employed battery energy systems. For the operation of gliders, a weight compensating mechanism could also be implemented.

摘要： A method for reducing the speed of propagation of a crack in a metal substrate by means of laser heat treatment can include heating the metal substrate with a laser heat treatment at one or more crack ends, wherein the laser beam is guided over the substrate surface so that it defines the form of an oval, an arc or a curve. Alternatively, the substrate can be treated by means of laser heat treatment before a crack arises. For example, areas at risk of cracking are identified in a metal substrate and the metal substrate is then heated by means of laser heat treatment in these areas, wherein the laser beam is guided over the substrate surface so that it defines the form of an oval, an arc or a curve. Also disclosed herein are metal substrates produced by the method and the use thereof.

摘要： The present invention relates to a double-multilayer monochromator. The monochromator comprises a base, a housing moveably mounted on the base and having in one side thereof at least one inlet window for the inlet of a X-ray beam and in another side thereof an outlet window for the outlet a monochromatized X-ray beam, support means mounted in the housing to support opposed mirror pairs, wherein each of the mirrors has a coated surface, each of said coated mirror surfaces being coated with a multilayer coating in alternating layers of a scatterer material (A) having a thickness dA and a spacer material (B) having a thickness dB. The present monochromator provides an enhanced purity of the synchrotron beam, where even and odd orders of higher harmonics are rejected. This is achieved in that the ratio dA:(dA+dB) on one of the facing mirrors of the mirror pairs is about 1:2 and the ratio dA:(dA+dB) on the other of the facing mirrors of the mirror pairs is about 1:3.

摘要： The present invention is directed towards a method for the preparation of macroporous or mesoporous polymer films in hollow fiber geometry. The method according to the present invention reliably produces macroporous or mesoporous homopolymer or copolymer films in hollow fiber geometry having an ordered porous structure. Preferably, the pores are isoporous. The method involves the purging or casting a polyol adjacent to a film forming polymer solution of at least one homopolymer or at least one copolymer in a suitable solvent while polyol diffuses in and then condenses out of the film forming solution before the solution is immersed into a coagulation bath. The methods also require the presence of a carrier solution or carrier substrate during spinning or casting. The method makes macroporous or mesoporous film formation possible with a single step processing method.

摘要： The present invention relates to a process and to an apparatus for producing a magnesium sheet from a magnesium strip in a rolling device, said process having lower material heat losses compared to known processes and requiring a lower expenditure on apparatus. In the process, the magnesium strip, after preheating, is guided through at least one roll nip formed by at least one pair of counter-rotating working rollers, which comprise a main roller body. The process is characterized in that at least one of the two counter-rotating working rollers comprises at least one heat-insulating sheath surrounding the main roller body.
