Patents by Inventor Bernd Ulrich Herbert Keller

Bernd Ulrich Herbert Keller has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Web offset press as well as method for operating the web offset press
    Patent number: 8347785
    Abstract: A web offset press includes several printing units through which a web passes essentially in a horizontal direction. The printed web then passes to at least one first folding unit. Each of the printing units has at least one plate cylinder and one transfer cylinder which interacts with the web being printed. An effective plate width of the plate cylinder corresponds to the print image of at least eight upright or prone printed pages in a BIN 4A format. The printed web is slit longitudinally into a plurality of web strands: A first number of these web strands are supplied to the first folding apparatus. At the same time, a second number of web strands, produced by the slitting of the same web, are supplied to a second folding apparatus for further processing.

  • Method and device for reducing vibrations on rotating parts, and vibration-damped rotating part
    Patent number: 7111555
    Abstract: A method and a device is used for reducing vibrations on at least two rotating elements, such as cooperating cylinders, which roll in opposite directions while situated in contact with each other. At least one of the elements has a surface protrusion that projects from an essentially circular contour of an active lateral surface. A height of this protrusion can be altered in a radial direction. A circumferential position of the protrusion can also be altered, all in accordance with a quality that characterizes a machine state or vibration.

  • Method and system for compensating the vibrations of rotating components
    Patent number: 6938515
    Abstract: Flexural vibrations are reduced in rotating components, such as rotating cylinders of a rotary printing press. One or more actuators are placed in a groove or recess in the cylinder. These actuators act in the axial direction of the rotating component. The amount of force exerted by said actuator will vary with the rotational position of the cylinder.
