Abstract: Two press units have axes which lie in a pressing plane which is inclined to the vertical direction and they form a press nip with each other. The two press units are supported by bearing brackets which are coupled in pairs to each other by detachable tension bars which transmit the pressing force. The bearing brackets of the one press unit are supported rigidly (i.e. directly on a machine frame, foundation, or the like) and bear at least a part of the weight of the other press unit. A support device on the machine frame, foundation, or the like at least temporarily takes up a component of the weight of the other press unit which is directed transverse to the pressing plane.
Abstract: An apparatus is described for depositing a thin film (9) of compound materials on selected substrates (48) in an evacuable coating chamber. This apparatus includes a rotating primary surrogate magnetron cathode surface (19) which acts to receive, in-situ, material to be sputtered. Vapor crucibles (2) expose the rotating cathode surface (19) to material vapors (8) which condense on the thermally cooled cathode surface (19) to combine with other coatings on the cathode and are thence rotated through the associated plasma sputter zone (26P) to sputter deposit desired film (9). Auxiliary rotating magnetron cathodes (32) can deposit additional material onto rotating primary cathode (19). Molten material crucible assemblies (31) having coating rollers (34) can convey molten material onto rotating auxiliary thermally cooled cathode surfaces (32) which sputter coat primary cathode.
Abstract: A method for real time message transmission in a token ring network is provided. The method initializes each node in the network, including setting a maximum message transmission time H.sub.i such that ##EQU1## is the transmission time of a message in a message stream, P.sub.i is the period length of the message stream, TTRT is the target token rotation time, and .tau. is the portion of TTRT that is unavailable to transmit messages. The messages are then transmitted when a token arrives at a node for the duration of H.sub.i. Using this method with the timed token protocol, the synchronous messages are guaranteed to be transmitted before their deadlines if the utilization of synchronous messages is no more than 33% of available utilization.

Abstract: The description relates to a process for determining the position of a positioning body in relation to a reference body in which the positioning body has a scale with markings at constant distances and the reference body has a scanner with a projection surface on which the markings of the scale are projected by imaging optics. The coordinates of the projection center of the imaging optics are trigonometrically calculated from the projection angles between the projection center and three markings arranged on the scale and from the constant distance between the markings. In addition, the angle of inclination of the positioning body in relation to the reference body is trigonometrically calculated via the co-ordinates found for the projection center, the distance between the projection center from the projection surface of the scanner and the image co-ordinates of the base of the vertical position of the position center above the projection surface.
