Title: Verfahren zum Transport einer Nutzlast in den Weltraum
Inventor: FUERSICH MANFRED
IPC: B64B1/00
Filed: 1999-10-21
Abstract: Offenbart ist ein Verfahren zum Transport einer Nutzlast in den Weltraum. Eine dafür ausgelegte Vorrichtung besteht aus mindestens zwei Modulen. Das erste Modul stellt einen Helium gefüllten Ballon 1 dar. Das zweite Modul ist ein aerodynamisch geformtes Fluggerät 2, das bei hohen Geschwindigkeiten die Flugeigenschaften eines Flugzeugs aufweist. Mit Hilfe des Ballons wird das System in eine Höhe von etwa 18 km gehoben. Anschließend wird das Modul 2 abgetrennt. Nach einem freien Fall von etwa 16 km hat das Modul 2 soviel Geschwindigkeit aufgenommen, daß die aerodynamischen Eigenschaften wirksam werden. Hierdurch kann das Fluggerät in eine horizontale Fluglage übergehen. Die Triebwerke werden eingeschaltet und es erfolgt eine Beschleunigungs- und Steigphase in der oberen Atmosphäre und anschließend in den Weltraum. Das Fluggerät ist hierzu vorteilhafterweise mit Raketenantrieben ausgestattet. Das Verfahren erlaubt es, bei gleichem Startgewicht die Nutzlast gegenüber einem horizontal startenden System um etwa 50% zu steigern.

Abstract: The invention relates to a so-called bone cement, e.g. based on polymethylmethacrylate, polystyrene or copolymers, whose particles comprised of e.g. polymerizate, additives and/or contrast media have a globular, preferably spheroidal, shape and form the powdery constituents. The invention also relates to an advantageous contrast medium itself, whereby these particles comprise, in essence, relatively large uniform dimensions and preferably form a hexagonally close sphere packing when mixed with the monomer. The invention also relates to a bone cement comprising an accelerator which has an improved physiological acceptability and comprising a catalyst that is specially deposited on the particles. The corresponding bone cement mixtures can be mixed without difficulties and without the risk of entrapping air. The required quantity of monomers is reduced, the heat emission and the volume shrinkage during polymerization are lower, the bending tensile strength of the cured product is at least identical or greater, and the abrasive effect is reduced. In addition, a reduced residual quantity of monomers is expected. The constituents of the inventive bone cement can be produced economically and without technical difficulties. As a result, the invention can contribute, in a field of medicine, to the technical further development that leads to the improvement in the well-being of the patient.

Title: Compact spring assembly returns a hydraulic piston, a clutch or a brake assembly from the operational position to the stand-by position
Inventor: KOERNER TILLMANN
IPC: F16D13/52
Filed: 1999-12-03
Abstract: Following operation or application of a hydraulic piston, a clutch or a brake assembly in which the unit is advanced to its operating position, the unit is then reversed to a holding position. The reverse motion is effected by two components having frictional surfaces which are coupled and de-coupled by a third intermediate frictional component. Springs with guides are located between the first two frictional components and the third intermediate component. The springs are compressed during operation of the piston, clutch or brake and generation of frictional forces. On release of the application force, the springs separate the frictional surfaces, and indirectly return the hydraulic e.g. brake piston to the stand-by position.

Filed: 2000-03-29
Abstract: Enhanced telepresence and telesurgery systems automatically update coordinate transformations so as to retain alignment between movement of an input device and movement of an end effector as displayed adjacent the input device. A processor maps a controller workspace with an end effector workspace, and effects movement of the end effector in response to the movement of the input device. This allows the use of kinematically dissimilar master and slave linkages. Gripping an input member near a gimbal point and appropriate input member to end effector mapping points enhance the operator's control. Dexterity is enhanced by accurately tracking orientational and/or angles of movement, even if linear movement distances of the end effector do not correspond to those of the input device.
