  • Patent number: 7559410
    Abstract: An electric drive for a parking brake is disclosed, the brake having a rotationally driven screw nut which is in engagement with two spindles which are aligned with one another, have threads running in opposite directions, and which are fixed in the rotational direction, can be moved in a translatory fashion and are each provided with a cable holder for connecting to brake elements. Here, one of the two spindles is a hollow spindle whose internal diameter is greater than the external diameter of the other spindle so that when the screw nut rotates, the spindle on one side can be retracted in a telescopic fashion into the hollow spindle on the other side.

  • Patent number: 6630563
    Abstract: A process for producing polycarbonate is disclosed. The process entails obtaining an oligocarbonate produced by transesterification of diaryl carbonate with dihydroxyaryl compound in the presence of catalysts and introducing the oliogocarbonate into a reactor that enables continuous formation of free films at a rate higher than 10. The reactor including a horizontal cylinder equipped with a heating jacket, at least one vapor outlet, a feed nozzle an outlet nozzle, a rotatable cylindrical basket having a cylindrical perforated wall and annular discs positioned at intervals around the periphery of said basket and along the length thereof, and means for rotating said basket, the interior of said basket including no central shaft, the diameter of the cylindrical basket corresponding to about ⅔ of the diameter of the horizontal cylinder, and said discs being formed of perforated sheet metal.

  • Patent number: 6444030
    Abstract: An apparatus applies a liquid or viscid coating medium onto a moving material web, especially one made of paper or cardboard. A coating mechanism first applies the coating medium onto an applicator element or an applicator roll, which subsequently transfers the coating medium at a coating location onto the material web in the form of a coating layer. Furthermore, if so desired, a doctoring device can be positioned at a doctor station, adjacent to the coating location, on the downstream side relative to the movement of the material web for the purpose of smoothing and/or metering the coating. The coating apparatus incorporates an apparatus for the generation and/or supplying of a fluid, preferably steam. This apparatus is positioned adjacent to the coating location or to the doctor station on the downstream side relative to the movement L of the material web.

  • Patent number: 6146058
    Abstract: A seal processing station for gathering loose and transmitting properly oriented seals to an insertion station where the seals are to be placed on a wire, the seal processing station having a seal sorting unit and a seal feeding unit that has a feed track going between the seal sorting unit and the insertion station where the seal sorting unit has a container where the loose seals are placed and a seal propulsion device with a seal feed channel extending from a lower end of the container to an upper end where the channel includes an air inlet for blowing air up the channel to feed seals from the lower end to the upper end and unto the feed track.

  • Patent number: 5779986
    Abstract: The reactor device comprises a horizontally-disposed housing (1), at one end of which there is disposed an inlet (4) for supply of the medium, and at the other end of which there is an outlet (5) for the reaction products. Within the housing (1) of the reactor device a rotor (1) is rotatably mounted. The rotor (8) has a hollow cylinder (9), which is provided with openings (10) and annular members (12, 13) for moving and transporting the medium. The hollow cylinder (9) is partly immersed in the free-flowing medium, the openings (10) in the hollow cylinder (9) ensuring additional admixture of the medium.
