  • Tool head for a rotating tool
    Patent number: 8814482
    Abstract: A tool head (10) for a rotating tool (2) includes a basic body (8), an annular portion (12) arranged on an end face on the basic body (8) and surrounds a cavity (22), and an adjusting device (18) including an adjusting screw (32) with a shank (34) and an adjusting sleeve (20). The shank (34) having a first shank portion (36) engaging a threaded bore (44) in the basic body (8). The adjusting sleeve (20) is displaceable by the adjusting screw (32) and has a conical outer face (30) that interacts with an inner face (28) of the annular portion (12) in such a way that, when the adjusting screw (32) is being screwed into the threaded bore (44), the annular portion (12) is spread open by the adjusting sleeve (20).

  • Device for contactlessly gripping and positioning components
    Patent number: 6647791
    Abstract: A mechanism for the contactless gripping and positioning of a component having a planar peripheral edge region, including a sound producing device producing a pattern of levitation sound waves for keeping the component in suspension at a selected position. The sound producing device is configured wherein only the peripheral edge region of the component lies in the sound wave pattern to be acted upon thereby and is fixed in the sound wave pattern by Bernoulli forces. The total surface area of the sound producing device is less than the component's total surface area facing the sound producing device.
