  • Patent number: 4803716
    Abstract: An x-ray diagnostics installation for radiographs has a secondary radiation grid disposed in front of a holder for x-ray film. The secondary radiation grid is moveable during an exposure. Control circuitry controls the speed of movement of the secondary radiation grid dependent on the anticipated exposure time, such that imaging of the lamellae of the secondary radiation grid on the x-ray film is reliably prevented for all exposure times.

  • Patent number: 4748650
    Abstract: In an exemplary embodiment a fine electron beam is generated which impinges on an elemental part of an anode focus region. A beam deflection system is controlled by a control circuit such that the point of impingement of the electron beam on the anode focus region moves along a predetermined path whose configuration effectively determines the desired focus size and shape.

  • Patent number: 4635426
    Abstract: An expansion joint unit is made up of two side sections and an expansion joint strip made of a resilient material and bridging the joint with its center portion. The edge portions of the expansion joint strip are vulcanized to the side sections. Disposed between the expansion joint strip and the side portions are separating strips defining chambers which are inflatable by way of openings.According to the method, a pump and/or pressure gauge is connected to the openings for supplying compressed air to the closed space and the pressure is observed over a period of time. A drop in pressure is a clear indication of a defective expansion joint element.

  • Patent number: 4478522
    Abstract: The driving mechanism of the day of the month disk (18) comprises a driving wheel (14) and a transmission wheel (16) The driving wheel (14) comprises a toothed sector (26'a, 26'a) which can mesh with the pinion (44) of the transmission wheel (16) and peripheral wall surface (26'a) into which open the two ends (30' and 30") of an arcuate groove (30). The transmission wheel (16) also comprises a member constituted by four arms (48a to 48d) carrying four studs (50a and 50d) which can enter the groove (30) and a pinion (52) which meshes with the disk (18). Outside the driving phases, two of the studs abut against the peripheral wall surface (26'b) in order to lock the disk (18). This mechanism provides for a low torque which enables the energy to be applied to the motor of the watch to be reduced.

  • Patent number: 4071994
    Abstract: An expansion joint for roofs and the like, especially for the sheet-metal flashing or cover plates of the finial, cresting or ridge of flat roofs, comprises a pair of metal strips defining an expansion gap between them. The gap is bridged on the underside of the joint with an elastomeric sealing band bonded, e.g., by vulcanization, to the metal strips and covered, on its side turned toward the environment with an intermediate metal strip slidingly held in place by the elastomeric band so as not to impede relative displacements of the first two metal strips upon thermal expansion and contraction.
