    摘要: A deployable antenna reflector comprising a central dish and a plurality of deployable sheet-like panels arranged around the central dish. The reflector further comprises a central supporting body, whereon the central dish is fixedly mounted and whereto the deployable sheet-like panels are hinged. The rotation axes of the individual deployable sheet-like panels are tilted with respect to the center point of the central dish. In the stowed configuration of the reflector, the deployable sheet-like panels are at least partially deflected in order to minimize the envelope of the reflector and that the panels relax upon deployment.

    摘要: This invention relates to a process and a device for producing components and semi-finished products from synthetic graphite or from ceramic granules, in particular for producing graphite tubes, involving shaping of a material to be mixed preferably containing petroleum coke or graphite granules, by means of an extrusion press (22) or an extruder, wherein the process provides the following steps: a) Pre-pressing the material (20) to be mixed in static or quasi-static manner, flow movements of the material (20) to be mixed being stopped or impeded in such a way that particles previously irregularly arranged in the material to be mixed are initially aligned transversely to the direction of pressing, b) Pressing out of the pre-pressed material (20) to be mixed through an outlet opening (28) of the extrusion press (22) or the extruder in such a way that owing to adjusted flow properties of the material (20) to be mixed, the particles within the pre-compressed material (20) to be mixed realign, starting from their transverse alignment, by an angle (β) of a maximum of 75° in the direction of pressing.

    摘要: A sheet feeder comprises a support adapted to hold a stack of sheets, and a straight guide rail extending from the stack parallel to a transport direction and defining a transport path extending in this direction. A generally cylindrical sheet-lifting roller is provided above the support and is vertically engageable with the topmost sheet of the stack, this lifting roller being centered on and rotatable about an axis inclined to the transport direction and rail. This lifting roller can be rotated about the respective axis while in contact with the topmost sheet of the stack for displacing the topmost sheet in the transport direction and toward the rail. Feed rollers downstream of the lift roller are rotated to advance a sheet engaged thereby along the transport path in the transport direction.
