    Abstract: A unitary flexible information presentation board having self-suction is disclosed. The board comprises a unitary flexible sheet having an exterior convex surface, an interior concave surface and a beveled periphery. Each surface is uniquely tapered to allow the interior concave surface, when placed against a substrate, to form a vacuum seal against said substrate, upon application of pressure from the exterior convex surface and thereby adhere to the substrate by self-suction action, without the need for an extraneous suction cup member. It thereby resembles an oversized suction plate upon which information can be prominently displayed. The board can be removed, attached and reattached to substrates without damaging these substrates. The board can be lifted off the attached substrate by lifting of the beveled periphery of the board. Lifting of the periphery of the board releases the vacuum seal formed.

    Abstract: The invention is directed to an optical instrument comprising a housing and at least one optical assembly enclosed by said housing and mounted on a stage plate. The stage plate is supported on the base plate with the aid of supporting means which guarantees on the one hand a precise fixing of the stage plate compared to the base plate and thus the housing, and on the other hand allows the base plate to distort by whatever attacks without a transfer to the stage plate. There are three supporting structures of different kinds which fix three different points in a special way. Upon the disconnection of the third supporting structure the stage plate can be lifted like a lid around an axis which is the middle axis of the first and second supporting structure.

  • Patent number: 5273249
    Abstract: A support system for coupling elements of different temperatures while reducing thermal and dynamic stress. The support system couples a fuel manifold to a combustor in a gas turbine engine and includes first and second elongated brackets connected, respectively, to the combustor and to the fuel manifold. Distal ends of each of the brackets are positioned in overlapping relationship. A slot is formed in one of the overlapping distal ends and an aperture formed in the other aligned generally with the slot. A fastener extends through the aperture and slot compressing the ends against each other with a preselected force such that the ends cannot separate but can exhibit a sliding motion in the slot direction. The compressive force is controlled by a spring member positioned between one end of the fastener and an adjacent surface of one of the first and second brackets. A second disk fits around the stud similar to a large flat washer and the spring member fits around the stud between the two disks.

  • Patent number: 5051061
    Abstract: In order to compensate for the axial displacements of the rotors of steam turbines occurring in operation by simultaneous displacement of the inner casing (11, 12) and, by this means, to keep the axial clearance between the stator and rotor blading rows constant, the inner casing (11, 12) of a double-casing turbine is supported in its outer casing (9, 10) so that it can be displaced relative to it. Lever pairs (18, 19), each having a two-arm displacement lever (20, 27), which is supported on bearing blocks (21, 28) fixed relative to the outer casing, and an expansion lever (22, 29) interacting with it are used for the displacement. An extension (.DELTA.l), occurring due to the operational heating in a section of length (1) of the inner casing (11, 12), between two bearing trunnions (23, 26) is transmitted by the expansion levers (22, 29) to the displacement lever (20, 27), whose pivoting about the bearing trunnion (26) in the clockwise direction achieves the necessary displacement (.DELTA.x, .DELTA.x2).
