摘要： The invention relates to a cold start apparatus for an exothermic hydrogen consumer such as a fuel cell and also a method for operating an exothermic hydrogen consumer having a metal hydride store or hydrogen supply from a reformer. It is an object of the present invention to provide a fuel cell having an efficient cold start apparatus, which can be taken into operation immediately and does not require any pressure tank. Furthermore, the cold start apparatus should be available for an unlimited number of starting operations. The object is achieved by an apparatus for operation of a fuel cell or another exothermic hydrogen consumer, which comprises at least one starter tank comprising a metal hydride having cold start properties and also at least one operating tank comprising at least one intermediate-temperature hydride or at least one reformer, wherein the starter tank is in fluidic communication with the exothermic hydrogen consumer and the operating tank or the reformer, wherein the first starter tank comprises a metal hydride which has an equilibrium pressure for desorption at a temperature of −40° C. of at least 100 kPa and further comprises a cooling device in order to be able to be reloaded with hydrogen by the operating tank or the reformer while the fuel cell is being supplied.

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.

摘要： A friction welding tool having a pin and a clamping device with a counter bearing, a holddown element and a spring element. The pin has a coupling section for releasable, rotationally fixed coupling to a rotating output device of a machine tool. The counter bearing is held on the pin between the pin's coupling and engagement ends in a manner that allows the counter bearing to be axially immovable on but freely rotatable about a longitudinal axis of the pin. The holddown element surrounds the pin and is arranged on a side of the counter bearing facing the engagement end. The holddown element has a bearing surface for bearing on the workpiece arrangement. The spring element is provided between the holddown element and the counter bearing and is mounted on the pin in such a way that it is elastically slidable along the longitudinal axis of the pin.

摘要： A reflector for a time-of-flight mass spectrometer for reflecting ionized atoms and/or molecules, with an entry opening and with an arrangement of successively arranged ring electrodes extending away from the entry opening along a longitudinal axis of the reflector is illustrated and described, as is a time-of-flight mass spectrometer. The object of providing a reflector for a time-of-flight mass spectrometer or providing such a mass spectrometer, with improved mass resolution at a high detection probability, is achieved by virtue of the fact that the ring electrode closest to the entry opening serves as a correction electrode and is at an opposite electric potential compared to the other ring electrodes, that a screening electrode is provided on the side of the entry opening facing away from the ring electrodes and that the screening electrode lies at a potential that differs from that of the ring electrodes, more preferably at earth potential.

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： 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.
