  • Patent number: 6266256
    Abstract: The invention relates to a circuit for power-factor correction having a rectifier (14) which can be connected on the input side to an AC voltage source (10) and which is connected on the output side to at least one series circuit comprising a capacitor (CS1) and a diode (DS1), with the diode (DS1) being arranged such that the capacitor (CS1; CS2) cannot be charged through the diode (DS1; DS2) by the output signal from the rectifier (14), a first and a second electronic switch (T1, T2) connected in series as part of a half bridge or full bridge, each having a freewheeling diode (DF1; DF2) connected in parallel with the switch (T1; T2) and, with the [lacuna] formed by the junction point between the first and second switches (T1, T2) [lacuna] an output connection of the half bridge or full bridge is on the one hand connected via an inductance (L) to a point on the connection of the capacitor (CS1) and diode (DS1) of each series circuit comprising a capacitor (CS1) and a diode (DS1), and on th

  • Patent number: 4577949
    Abstract: A developing device for a photographic layer carrier, particularly a film, includes two rotary transport roller pairs transporting a film in a horizontal direction over a bath containing a processing liquid. Two liquid-admitting chambers are positioned opposite to each other in spaced relationship to form a processing space through which the film is transported. Each chamber is subdivided into two portions by a comb-like partition which loosens vortexes generated in one chamber portion upon pumping the liquid thereinto and ensures a uniform distribution of the liquid discharged into the processing space through a slot provided in the second chamber portion.

  • Patent number: 4574852
    Abstract: In a feedpipe of a container for refilling a photographic developing tank with a developer radial discharge holes are provided in the region of a valve mounted at the lower end of the feedpipe extended outwardly of the container. The developer liquid is discharged into the valve and then into the tank through these radial holes. To prevent overflowing of the liquid through these holes meshed elements are inserted into the radial holes.

  • Patent number: 4514071
    Abstract: A coupling device for transmitting torque from a first film transporting rack to a neighboring second film transporting rack in a developing machine has a first shaft extending outwardly from a sidewall of one of the racks, a second shaft which extends outwardly from one sidewall of the other rack and is movable into axial alignment with the first shaft, first and second gears on the respective shafts, and a sleeve having an internal gear which is in permanent mesh with one of the gears and is movable axially into and from mesh with the other gear. The sleeve has internal elastic prongs which extend into a circumferential groove of the shaft for the one gear when the internal gear meshes with the other gear.

  • Patent number: 4420241
    Abstract: A film-treatment device has two spaced and generally parallel mounting plates each having a pair of plate holes and respective pairs of journals in the plate holes having respective journal holes centered on a pair of journal axes. The journal holes of the plates are coaxial with each other and the two journal axes are parallel. Rollers centered on respective roller axes each have a pair of substantially cylindrical end trunnions centered on the respective roller axis and rotatably received in a respective one of the journal holes for rotation of the respective roller therein with its roller axis coaxial with the respective journal axis. The journals of one of the journal axes are constructed so the respective roller can move against spring force limitedly away from the other roller.
