Abstract: FIELD: space industry. 
     SUBSTANCE: invention can be used for analysing the operation of a wide class of technical systems, in particular, in rocket and space equipment for monitoring the state of a liquid rocket engine (LRE) in transitional modes of firing bench tests. To make decisions about the occurrence of a malfunction, the termination of the test and the determination of a malfunctioning aggregate in transitional modes of a bench test, time series of change gradient values in the measured parameters, exhibiting a property of stationarity attributed to the fact that during the bench tests conducted according to a preset cyclogram, in transitional modes, the engine is controlled by linearly changing the drive angle of the control aggregate, are subjected to statistical evaluation according to the Student criterion. If the current values of the statistical characteristics exceed the threshold values thereof, the fact and the moment of the occurrence of a malfunction are recorded and the LRE testing is stopped to prevent the development of the detected malfunction, wherein the malfunctioning LRE is determined based on the measured parameter, the statistical characteristics whereof first exceeded the threshold values, and is subsequently replaced with a functional one. 
     EFFECT: in transitional modes of fire bench tests of an LRE, identification and compensation of the influence of developing malfunctions on the engine become possible, ultimately ensuring deactivation of the engine before occurrence of irreversible changes and prevention of catastrophic consequences.

Abstract: Aufgabe war, ein Verfahren zum epitaktischen Niederschlagen einer im wesentlichen einkristallinen, aus einem Halbleitermaterial bestehenden duennen Schicht auf einem Substrat unter Verwendung einer Zwischenschicht anzugeben, bei dem die an sich mit Heteroepitaxie-Verfahren verbundenen Fehlerquellen verringert werden. Eine Loesung dieses Problems wird dadurch erreicht, dass die Zwischenschicht so ausgebildet wird, dass zwischen der Differenz der natuerlichen Atomabstaende von Zwischenschicht und Substrat und der Differenz der natuerlichen Atomabstaende von epitaktisch niedergeschlagener Schicht und Substrat die Beziehung gilt, dass die erstgenannte Differenz groesser ist als die letztgenannte Differenz, und dass weiterhin die Dicke der Zwischenschicht so gewaehlt ist, dass der tatsaechliche Atomabstand in der Zwischenschicht gleich ist dem natuerlichen Atomabstand in der Schicht. Das Verfahren bietet den Vorteil, dass die Auswahlmoeglichkeit unter den  fuer eine bestimmte Substrat-Schicht-Kombination geeigneten Zwischenschichtmaterialien erheblich vergroessert wird.                                                                                                                                                                                                                                                                                                                                                                                                                        ...U.S.W

Granted: 1985-04-04
Abstract: This invention deals with a method of burning crushed or lump-sized combustible material, such as limestone, dolomite, magnesite or a similar material, in an annular shaft kiln having an annular outer shaft and an inner shaft, where the annular and the inner shafts are alternatively charged with fresh air and combustion gases, or are connected with the exhaust gas system. Furthermore, the invention deals with an annular shaft kiln for carrying out this method, which has a shaft insert that is open at the top, whereby the combustion material is selectively fed into the annular shaft formed around the shaft insert, or into the inner shaft which is formed inside the shaft insert. In a first operating position, the inner shaft adjacent its upper end is connected with the exhaust gas system, and combustion gas and combustion air are fed into the outer annular shaft. In a second operating position, the inner shaft is fed with the combustion air and the combustion gas, while the annular shaft adjacent its upper end, is connected to the exhaust gas system. Thus, in the first operating position, the annular shaft has air passed it and the inner shaft has gas flowing through it in counter flow, the flows being parallel, and in the second operating position the annular shaft has gas passed through it in counter flow and the inner shaft has air passed through it in parallel flow.

Abstract: Die Erfindung betrifft ein Verfahren zur Belichtung eines auf einem Substrat aufgebrachten Photolacks unter Verwendung einer Roentgenstrahlungsquelle, welche sich in einem evakuierten Gehaeuse befindet, das ein fuer Roentgenstrahlen durchlaessiges und mit einem Stuetzgitter versehenes Fenster aufweist. Roentgenquellen mit einem verstaerkten Strahlenaustrittsfenster sind fuer die Zwecke der Roentgenstrahllithographie nur unter gewissen Voraussetzungen brauchbar. Soll beispielsweise eine auf einem Substrat aufgebrachte Photolackschicht durch eine Maske hindurch belichtet werden, so wird bei Verwendung eines durch ein Stuetzgitter verstaerkten Fensters die Gitterstruktur der eigentlich abzubildenden Struktur ueberlagert. Der Erfindung lag daher die Aufgabe zugrunde, ein Verfahren anzugeben, welches die Belichtung eines Photolacks ohne stoerende Abschattierung durch das Stuetzgitter erlaubt. Diese Aufgabe wird erfindungsgemaess dadurch geloest, dass das Substrat und/oder das Fenster zumindest waehrend des Belichtungsvorgangs quer zur Ausbreitungsrichtungder Roentgenstrahlen bewegt wird und dass die Relativgeschwindigkeit zwischen Substrat und Fenster sowie die Bewegungsrichtung von Substrat und Fenster relativ zueinander derart gewaehlt werden, dass waehrend des Belichtungsvorgangs alle zu belichtenden Bereiche des Photolacks im zeitlichen Mittel gleich lange durch das Stuetzgitter abschattiert werden.                                                                    ...U.S.W
