Abstract: Bei einem Verfahren zum lagerichtigen Übernehmen von gefalzten Signaturen von einem Bandleitsystem auf einen Greiferzylinder ist unabhängig von der Oberflächenbeschaffenheit der Signaturen vorgesehen, die Lage einer vorbestimmten, das Bandleitsystem verlassende Signatur fortlaufend festzustellen und zu erfassen. Gleichzeitig wird die momentane Ist-Winkellage eines zur Übernahme der vorbestimmten Signatur vorgesehenen Greifersystems festgestellt und erfaßt, wobei bei einer Abweichung von einer Soll-Winkellage ein elektrisches Differenzwertsignal gebildet und der Greiferzylinder anschließend durch Antriebsmittel in eine Soll-Winkellage gebracht wird. Dazu wird auch eine Vorrichtung vorgeschlagen.

Abstract: Procédé et appareil permettant de manipuler des conteneurs océaniques chargés et vides à l'aide d'un système automatisé de stockage et de récupération (ASRS). Les conteneurs sont stockés dans une installation (10) pour conteneurs chargés à niveaux multiples dans des groupes en hauteur et à quai (14, 16) de rangées et de colonnes espacées selon une configuration en grille, chaque conteneur se trouvant dans un espace particulier étant séparé de tous les autres conteneurs, cette installation étant couramment désignée stockage à rayonnage dans les systèmes ASRS. Les conteneurs vides sont stockés dans un bâtiment séparé (12) situé à distance de l'installation de conteneurs chargés stockés, mais accessible depuis cette dernière et les conteneurs identiques du même porte-conteneurs sont empilés les uns au-dessus des autres directement dans des cellules séparées. Les conteneurs qui sont manipulés entre les groupes en hauteur (14) d'espaces et les groupes à quai (16) d'espaces sont déplacés entre les groupes en hauteur et à quai par un certain nombre de ponts-grues (20) internes informatisés. Les rangées en hauteur et à quai sont dotées de balcons (26, 36) de transport rapide externe qui permettent de déplacer rapidement un conteneur sur la longueur de l'installation de conteneurs chargés pour éviter les mouvements plus lents des ponts-grues (20) internes et donc d'utiliser un conteneur de manière plus rapide. De même, les conteneurs vides peuvent être déplacés le long d'un balcon (38) de transport rapide pour conteneurs vides situé en hauteur sur l'installation, ce qui permet d'éviter les mouvements plus lents des ponts-grues internes et, immédiatement avant de les charger sur le bateau, de déplacer les conteneurs d'un endroit situé le long de l'installation à un autre situé face à la grue de quai qui les chargera à bord d'un bateau. Ledit processus est inversé lorsque des conteneurs vides sont déchargés de bateaux.

Abstract: Mehrstufenregler für Schmiermittelpumpen mit kontinuierlich veränderbarem Fördervolumen, mit einem Stellkolben (1), welcher durch einen von der Ausgangsseite der Pumpe (10, 20) abgeleiteten Druck (P) beaufschlagbar ist und bei zunehmendem Druck gegen die Kraft eines nachgiebigen Rückstellelementes (2) verschiebbar ist. Um einen Regler für regelbare Schmiermittelpumpen zu schaffen, der bei möglichst einfacher Bauweise eine qualitativ günstigere Regelcharakteristik ermöglicht, die dem tatsächlichen Bedarf des Motors hinsichtlich Druck und Fördervolumen des Schmiermittels besser entspricht und somit weitgehend verlustfrei, d.h. ohne erhebliche überschüssige hydraulische Leistung, arbeitet, wird erfindungsgemäß vorgeschlagen, daß der Stellkolben (1) aus mehreren, gleichzeitig vom Druck beaufschlagbaren Teilkolben (3, 4) besteht, die über einen begrenzten Stellweg gleichzeitig parallel bewegbar sind, wobei für mindestens einen der Teilkolben (4) ein Anschlag (9) vorgesehen ist, der dessen Stellweg gegen die Kraftrichtung des Rückstellelementes (2) bei zunehmendem Druck begrenzt, während der andere Teilkolben (3) weiterhin gegen die Kraft des Rückstellelementes (2) bewegbar bleibt.

Title: Method of filling the fuel-feed system of an internal-combustion engine
Inventor: GRAS JUERGEN
IPC: F02D41/06
Filed: 1994-10-12
Abstract: Described is a method of filling the fuel-feed system of an internal-combustion engine, the method calling for the electric fuel pump to be controlled by a control unit. When the control unit determines, based on measurements of certain parameters, that it is necessary to fill the fuel-feed system with fuel, it commands the fuel pump to feed in sufficient fuel before the engine is started. When the control unit determines, however, that engine start-up will be normal, the normal procedure is followed for control of the fuel pump. It is also possible to change over from fuel-pump time control to normal control when the measured parameters correspond to recognized switchover conditions.

Abstract: The control system is used for a communication system with a number of identical transmission processors (P), coupled to one another and to respective line interfaces (LAE) with a number of outgoing transmission lines (UEL1..UELn). Each interface has a waiting loop (M2), with the momentary loading determined from the number of information blocks per unit of time and the flow rate, to block the transfer of further information blocks to the interface when a given max. loading is reached. The information blocks which are held back are stored in a waiting loop (M1) in the processor.

Abstract: The method involves the grinding material being accelerated by the blades (7) of a first rotor (6) and pulverized against the blades (9) of an oppositely rotating rotor (8). The pulverized material strikes at a low angle a filter (5) in the path of movement of the rotor (6) and is separated into fractions. The remaining coarse fractions are passed on in the direction of movement and subjected to renewed acceleration, impact and filtering. The first and third grinding stages take place in separate work areas (12,13) of the chamber (4). Acceleration and impact alternate cyclically in two intermediate zones which are connected together by streams of insufficiently pulverised material. <IMAGE>

Abstract: A method of fabricating dies (31,32,33) on a wafer (30), for integrated circuit devices (10). A single wafer (30) is used to fabricate dies (31,32, and 33) of different lengths. The dies (31,32, and 33) are arranged in a "stacked" pattern across the wafer (30), such that the dies are parallel with shorter dies (33) corresponding to shorter latitudes of the wafer (30) and longer dies (31) corresponding to longer latitudes of the wafer (30). Each die (31,32,33) has the same basic pattern of a left peripheral subcircuit, a repeating middle subcircuit, and a right subcircuit. The varying lengths of the dies (31,32,33) are accomplished by varying the number of repeating middle subcircuits.
