Title: Procédé de régulation de la puissance fournie par un réacteur nucléaire à eau sous pression à une turbine à vapeur
Inventor: PETETROT JEAN-FRANCOIS
IPC: G21D3/12
Filed: 1981-02-12
Abstract: L'invention concerne un procédé de régulation de la puissance fournie par un réacteur nucléaire à eau sous pression à une turbine à vapeur entraînant une génératrice de courant électrique alimentant un réseau. La régulation utilise le déplacement de barres de commande dans le réacteur et le contournement d'une fraction de la vapeur produite par le réacteur en dèhors du circuit de la turbine. En cas de désaccouplement électrique entre la génératrice et le réseau, ou ilôtage, le paramètre déterminant la position des barres de commande est choisi comme la plus grande de deux valeurs d'une température de référence. Le contournement de la vapeur est maintenu en fonctionnement et la conduite du réacteur reste automatique. Le signal d'ouverture des vannes de contournement est modifié par un signal de gain déterminé à partir d'un signal représentatif du niveau de puissance. L'invention s'applique en particulier à la régulation de la puissance des centrales nucléaires à eau sous pression.

Abstract: A method and apparatus for tracing errors during operation in progress in a sequence including a transfer series of binary message words between a plurality of electric circuits, which form a new message word from the obtained message word for transfer to the next circuit. The first message word in a sequence is provided with a marking word, and in each circuit the marking word is added to the new message word formed on the basis of the received message, and each message word is sensed during the transfer, the message word containing a marking word being copied into a memory. All message words provided with a given marking word are subsequently read out from the memory to determine whether the sequence provided with the marking word is correct.

Abstract: Semipermeable Membranen aus Polyacrylnitril oder Copolymeren aus Acrylnitril und anderen äthylenisch ungesättigten Monomeren werden durch Umsetzung mit (a) Hydroxylamin und (b) einer polyfunktionellen, mit Amidoximgruppen reaktionsfähigen und gegebenenfalls ionischen Verbindung oder einer Kombination aus anionischen und kationischen polyfunktionellen und mit Aminoximgruppen reaktionsfähigen Verbindungen modifiziert. Das Verfahren zur Herstellung der erfindungsgemässen Membranen erfolgt vorzugsweise durch Modifikation einer bereits vorliegenden Membran durch Umsetzung mit den Komponenten (a) und (b). Als Alternative zu diesem Verfahren kann die Reaktion mit Hydroxylamin auch unabhängig von der Membranbildung erfolgen, d.h. man modifiziert Polymere auf Acrylnitrilbasis mit Hydroxylamin und giesst aus diesen Polymeren dann die Membranen (auf ein Trägermaterial); die Vernetzung erfolgt dann wie angegeben. Eine weitere Alternative ist die Umsetzung mit Hydroxylamin in der Giesslösung. Sie sind als Umkehrosmose- und insbesondere als Ultrafiltrationsmembranen geeignet.

Abstract: Analog servo-positioning signals transduced from a recorded member (10), such as embedded servo signals (28, 30; 32, 34) recorded on a disc memory or the like, which are to be compared to one another in order to derive an error signal indicative of off-track position deviations, are normalized for accurate responsive positioning changes by use of an analog-to-digital converter (62) reference by both a positive and a negative summation of the two analog signals and supplied with the individual analog signals as inputs, such that the digitalized output comprises a pair of digital signals, the first representative of the quotient of the first analog signal divided by the summation of the two analog signals, and the second representative of the second analog signal divided by the same summation of analog signals. The two resulting digital signals are then processed in a microprocessor (68) by subtracting the second such quotient-representative signal from the first. thereby providing a fully-normalized digital signal representative of the deviation from true position. An analog multiplexer (66) is preferably used as a switching input to the A/D converter, and the latter comprises a multiplying type A/D converter.

Abstract: The cast tube (T) is subjected internally in a chill-mould (1) to the uniform spraying of water from 1000 DEG  C. approximately to 350 DEG C. approximately. Then it is extracted from the chill-mould and in a furnace is subjected to isothermal bainitisation maintenance, after which it is cooled in the atmosphere to ambient temperature. Without it being necessary to add expensive chilling elements, one thus obtains lightened tubes having very good mechanical properties and the ovalisation of which remains acceptable.

Abstract: Circuit provided with a number of data encryption standard circuits (DES).

Even if the same key should be supplied to both DES and if, due to an operating error, the first DES should have been set to encipher and the second DES should have been set to decipher, the clear text will be prevented from appearing at the output. At the same time a good protection against so-called weak keys is obtained.

Abstract: In a loudspeaker system for converting an n-bit digitized electric signal (6) into an acoustic signal a plurality of sections (voice coils 14.1, 14.2, 14.3, 14.p) of a digital loudspeaker (1) are driven directly by the p most significant bits of the n-bit digitized electric signal (6). The loudspeaker (1) comprises at least one additional section (14.p+1). This (p+1)<sup>th</sup> voice coil receives a signal from a digital-to-analog converter (5), the input signal of the digital-to-analog converter comprising at least the n-p least significant bits. In a different embodiment the digital-to-analog converter (5) receives all the n bits of the digitized electric signal as the input signal. At least the p sections (14.1 to 14.p) which correspond to the p most significant bits are provided with means (the resistances r) for producing a signal which is a measure of the sum of their instantaneous drive signals and for applying the said signal to a signal combination unit (32) arranged in the line (10) from the output of the digital-to-analog converter (5) to the (p+1)<sup>th</sup> section (R<sub>i</sub>).

Abstract: Cette presse à balles cylindriques (1) comprend des jeux de courroies (6), bandes ou analogues ménageant une chambre de formation de la balle par enroulement. Au moins un rouleau fixe d'entraînement des bandes est lui-même entraîné à partir d'un arbre principal (19). Certains des rouleaux de renvoi (9) sont mobiles et sont soumis à l'effet d'une sollicitation, par des cylindres hydrauliques (14) ou des ressorts, pour maintenir les courroies (6) en tension. Suivant l'invention, un détecteur de couple (20) est prévu sur l'arbre d'entraînement principal (19) de la presse (1) et est relié a ces moyens de sollicitation pour réduire ou annuler la tension dans les courroies lors de la détection d'un couple résistant excessif sur l'arbre d'entraînement principal. Dans le cas de cylindres hydrauliques (14) associés à une valve de détente (18), le détecteur de couple est relié à cette valve de détente pour abaisser son seuil de réponse en cas de détection d'un couple excessif. Une valve de dérivation (21) renvoyant le liquide vers le fond du vérin peut, suivant une variante, être montée en parallèle avec les cylindres hydrauliques (14). Elle est alors actionnée par le détecteur de couple. Celui-ci pourrait également déplacer l'un au moins des points d'attache de ressorts de sollicitation.
