Abstract: Die Erfindung betrifft ein Verfahren zum maschinellen Milchentzug, bei dem zum Entziehen der Milch an dem Innenraum eines an eine Zitze angesetzten Melkbechers ein Unterdruck vorbestimmter Höhe angelegt wird, und gegebenenfalls eine Pulsation eines Zitzengummis mit vorbestimmter Frequenz und Stärke durchgeführt wird, und bei angesetztem Melkbecher in einer Stimulationsphase während einer vorbestimmten Zeit vor der Hauptmelkphase auf die Zitze stimulierend eingewirkt wird. Das Verfahren ist bei allen maschinellen Melkverfahren anwendbar und verbessert den Ausmelkungsgrad wie auch die erhaltene Gesamtmilchmenge. Das Verfahren wird derart durchgeführt, dass während einer Zeit von 40 bis 90 Sekunden und vorzugsweise während einer Zeit von 40 bis 60 Sekunden ab Beginn dieser Stimulationsphase keine Milch entzogen und erst unmittelbar hieran anschliessend mit dem Milchentzug begonnen wird. Unter Berücksichtigung der Tatsache, dass bei manchen Kühen während der Stimulationsphase der Euterinnendruck übermässig ansteigen kann, wird das Verfahren vorzugsweise derart durchgeführt, dass während der Stimulationsphase die Pulsation des Zitzengummis mit einer um wenigstens 50% gegenüber der Frequenz der Hauptmelkphase erhöhten Frequenz erfolgt und dass während dieses Zeitraumes der maximale Pulsunterdruck im Pulsraum des Melkbechers in Abhängigkeit von dem Unterdruck im Innenraum des Zitzengummis und dem Einfaltdruck des Zitzengummis so gewählt wird, dass er in dem durch die Formel <IMAGE> angegebenen Bereich liegt. Es wird gleichzeitig eine Vorrichtung angeführt, mit der das Verfahren zweckmässig durchgeführt werden kann.

Abstract: An improved fuel cell arrangement having a non-uniform distribution of fuel and oxidant flow paths (26,28), on opposite sides of an electrolyte matrix sized and positioned to provide approximately uniform fuel and oxidant utilization rates across the entire cell. In conventional cross-flow type fuel cells, the entry corner exposed to both fresh fuel and fresh oxidant tends to develop a higher EMF than the exit corner exposed to both depleted fuel and depleted oxidant. The resulting uneven reaction distribution is undesirable. This invention improves the current, density and temperature distributions by providing the largest fuel channel (26') nearest the oxidant inlet and decreasing the fuel channels as the oxidant outlet is approached, while providing the largest oxidant channel (28') nearest the fuel inlet and decreasing the oxidant channels as the fuel outlet is approached.

Abstract: Il peut arriver qu'une feuille d'une liasse de documents ait un contraste ou une densite produisant une copie de qualite insuffisante lorsque la feuille est copiee par une copieuse en fonctionnement normal. Dans ce cas la pratique courante consiste a enlever la feuille de la liasse de documents et a la copier individuellement, en faisant une copie originale ou intermediaire. La copie originale est ensuite remise en place dans la position appropriee dans la liasse de documents et l'operation de copiage est recommencee. Cette demarche presente le probleme que pendant l'operation de copiage lorsque la copie originale est copiee, la qualite de l'image se degrade inevitablement. Conformement a la presente invention, le contraste et la densite des copies de feuilles particulieres d'un document compose d'un certains nombre de feuilles est ajustee pendant l'operation de copiage mais sans executer de copies originales. Avant l'operation de copiage, un operateur designe l'utilisation d'un ecran a demi-ton (13') et/ou d'une information de parametre de traitement permettant de commander le contraste et la densite d'une copie pour une feuille particuliere d'un document possedant une caracteristique de copiage sensiblement differente des autres feuilles de la liasse du document. Cette information est stockee dans une memoire (32) situee dans la copieuse. Pendant l'operation de copiage le dispositif (31) de logique et de commande provoque le transport sequentiel des feuilles de documents S par le dispositif d'avancement (50) du document vers les plaques d'exposition de la copieuse ou elles sont copiees et, conformement aux informations stockees, il actionne un ecran de demi-ton (13') et/ou fait varier les parametres de traitement de la copieuse pour produire un contraste et une densite de copiage ameliores des copies de la feuille particuliere du document.

Abstract: improvement in a signal transmitting and receiving device for transmitting and receiving the signals corresponding to an M-function, an S-function and a T-function between a numerical control unit and a machine tool. A redundant signal (pt) is added to each of the numerical codes (n, to n n ) transmitted from the NC unit to the machine, for checking the validity of the code, and the machine is operated only when it has been judged from these added signals that the received signal is valid. This reliably prevents mis-functions of the M-, S- and T- functions, even when using a parallel transmission system with a lot of signal lines.
