An electrochemical includes an electrode structure provided with a composite separator having a porous substrate with a plurality of pores and a porous coating layer formed on at least one surface of the porous substrate and made of a mixture of electrode active material particles and a binder polymer. The porous coating layer of the composite separator improves thermal stability of the porous substrate and plays a function of electrode active material layer of the electrochemical device. Accordingly, this electrochemical device has excellent stability and good economical efficiency since the electrode structure does not need coating of an electrode active material layer on a surface of a current collector.

A regeneratively coolable nozzle for a rocket engine is formed by winding a tubular material (6) onto a winding mandrel to produce a helical composite structure (5), through which a coolant can flow during operation of the nozzle. The spiral composite structure (5) is fixed temporarily and the fixed composite structure (5) is removed from the winding mandrel. Then an inner heat resistant, load bearing layer (9) is applied to the radially inner hot-gas facing surface (H) of the fixed composite structure (5). The present nozzle is lightweight and withstands a high coolant pressure.

Systems and methods for monitoring a data transmission link, especially an optical, bidirectional data transmission link, in which a digital transmit signal is transmitted on a first transmission path from a local end of the data transmission link toward a remote end of the data transmission link. A portion of the power of the transmit signal sent at the local end is transmitted, delayed by a non-zero delay time on a second transmission path as a control signal toward the remote end of the data transmission link. Both signals are received at the remote end and are tested for the presence of events of a predetermined type. A conclusion can be reached on the quality of the transmission link as a function of a time correlation and frequency of the appearance of events in the received transmit signal and in the received control signal.
