Patent DE-4318073-A1 (DE)
Title: Radial piston pump with pot-shaped pistons - uses inserts concentric with piston springs to minimise fluid dead space
Inventor: HERTELL SIEGFRIED
IPC: F04B1/053
Filed: 1993-06-01
Abstract: Radial piston pump in which the pot-shaped pistons (3) are moved radially in cylinder housings (4) against the force of springs (8). The springs support themselves on the cylinder cover (5) and against the piston floor (3.1). A displacement insert body (10) is arranged in each piston concentrically with the spring. The insert is secured to a disc (9) which lies on the cylinder cover. USE/ADVANTAGE - Radial piston pump with pot-shaped pistons reduces the amount of dead fluid space in the cylinders, so avoiding a harmful damping effect.

Title: Ultrasonic testing device
Inventor: SCHMITZ VOLKER DR
IPC: G01N29/40
Filed: 1993-06-21
Abstract: In an ultrasonic testing device, the echo signals are detectable from the far field (14) of a single testing head (11). The amplitudes and times of flight of the echo signals can be stored, together with the position of the testing head (11) in a memory unit (22) as time-of-flight/position curves with associated amplitude values. In a filter device comprising, for example, three filters (29, 33, 37) connected one after the other, with in each case presettable filter functions, the set of time-of-flight/position curves can be filtered such that reconstruction of fault (interference) sites (2, 3, 4, 5, 6) of a test body (1) can be carried out stepwise. <IMAGE>

Filed: 1993-12-23
Abstract: In a plug coupling, an inner polygonal portion (2), which is to be joined by plug connection to an outer polygonal portion (14), has an outwardly directed trumpet-shaped widened portion (3). In its walls, this has a saddle (13) projecting into the widened portion (3) between each of the corners of the inner polygonal portion (2). This causes the parts to rotate in relation to one another if they are plugged into on another in an angular position, in which the side surfaces (4, 5) of the inner polygonal portion (2) do not lie flush with those of the outer polygonal portion (14). The coupling may be used in the connection of a flexible driveshaft to a speedometer. <IMAGE>

Inventor: ZHANG JIANG DR
IPC: B60R22/46
Filed: 1994-06-08
Abstract: A belt tensioner (15) for vehicle safety belt systems, in particular for tensioning a belt retractor with a belt strap-receiving winding shaft, has a rotary piston engine that may be driven by a pyrotechnic gas generator (3). The output shaft (14) of the rotary piston engine carries an inner impeller wheel (8), and in particular the output shaft (14) may be coupled to the winding shaft of the belt retractor in order to drive it in the winding direction of the belt strap. In order to prolong the rotary movement with a defined end stop, an outer impeller wheel (4) with an outer expansion chamber (5) is coaxially arranged to the inner impeller wheel (8) and both impeller wheels (4, 8) are successively driven by pressurised gas. When it rotates, the outer impeller wheel (4) drives the inner impeller wheel (8). Shortly before the end of the rotary movement of the outer impeller wheel (4), the pressurised gas contained in the outer expansion chamber (5) flows into the inner expansion chamber (9) and drives further the inner impeller wheel (8).

Patent DE-4423033-A1 (DE)
Inventor: BERGMANN KLAUS DIPL ING
IPC: H02J3/18
Filed: 1994-07-01
Abstract: The invention concerns a three-phase reactive-power controller for a static compensator. The invention calls for the three phases (2, 4, 6) of the controller to be connected up in a star-configuration, two phases (2, 4) each consisting of an element (10) which can be switched in by means of a switch (8) and the third phase (6) simply consisting of an element (10), these elements (10) producint idling power. This gives an extremely inexpensive three-phase reactive-power controller in which one switch (8), together with the associated accessories, has been dispensed with and which thus requires much less space, hence making it possible to produce a mobile static-compensator installation housed in one or more containers and made up of several reactive-power controllers as proposed.

Abstract: Für jede Teilaufgabe der Einheit, wie beispielsweise fahre von A nach B, halte deine Positionsunsicherheit unterhalb einer bestimmten Schwelle, bzw. erstelle eine Umgebungskarte und füge dieser Landmarken hinzu, werden unterschiedliche Bonus- und Maluswerte vergeben. In Verbindung mit einer Notwendigkeit zur Durchführung dieser Aufgaben ergeben sich nach Analyse der Bonus- und Maluswerte Durchführungsgewichte für die einzelnen Aufgaben, welche in einer Steuereinheit ausgewertet werden. Im Rahmen des Verfahrens wird weiter ein lokaler Planungshorizont angegeben, in welchem die Umgebung der Einheit in Gitterzellen unterteilt wird. Für diese Gitterzellen werden Vorzugsrichtungen abgespeichert, welche die Einheit auf dem kürzesten Weg zu bereits bekannten oder unbestätigten Landmarken führen, mit dem Ziel, die Positionsunsicherheit zu verringern oder eine Landmarke bestätigen zu können. Alle unterschiedlichen Fahrwege, die im Rahmen dieses Gitters möglich sind, werden daraufhin untersucht, welchen Beitrag sie leisten, um der Einheit das Erreichen des Zieles zu ermöglichen. Dabei werden die unterschiedlichen Kosten und Nutzen je Teilaufgabe entlang eines jeden Weges aufsummiert. Es wird derjenige Fahrweg ausgewählt, der den größten Nutzen bzw. den geringsten Verlust aufweist. Durch zyklische Ausführung des Verfahrens wird schließlich ein Zielpunkt erreicht, der außerhalb des lokalen Planungshorizontes liegt.
