Patents by Inventor Peter Langenbeck

Peter Langenbeck 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).

  • Aerostatic and aerodynamic bearing for a motor
    Patent number: 5789839
    Abstract: The invention relates to a high precision axial and radial aerostatic and aerodynamic bearing for a motor. The bearing surfaces of the stator and the rotor are of a toroidal shape.
    Type: Grant

  • Method and apparatus for the focal form cutting of a moving web of material by a laser beam
    Patent number: 4160894
    Abstract: A desired pattern to be cut from a moving web of material by a focused laser beam is traced by eccentrically mounting the focal lens 3 in a rotatable carrier 4. The lens may also be radially displaceable (FIG. 3), inclined and rotatable (FIG. 4), doubly rotatable (FIG. 5), and/or the carrier 4 may be linearly displaceable (FIG. 6). By suitably and simultaneously controlling the various motion parameters, whose resultants are superimposed on one another, any desired cutting pattern can be traced. The movements are primarily uni-directional rather than oscillatory, which greatly simplifies the implementing hardware, and since all of the laser beam reflecting mirrors involved are fixedly mounted and move only in planes parallel to the web, the laser beam focal length always remains constant.

  • Method of and apparatus for cutting material to shape from a moving web by burning
    Patent number: 4049945
    Abstract: A method and apparatus for cutting a predetermined pattern in a moving web of material, such as paper, cardboard or the like is disclosed wherein a laser beam is deflected by a series of pivotable mirrors. The pivoting of the mirrors is controlled so as to cause the laser beam to trace and cut a predetermined pattern. The laser beam moves only in rectilinear motion, as does the web of material to be cut. Since the directions of motions are not parallel, any pattern may be cut by controlling the relative speeds of the laser beam and the moving web of material.
