Patents by Inventor Josef Stirnimann

Josef Stirnimann 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).

  • Patent number: 8376666
    Abstract: The invention relates to a tool having a tool element which rotates in operation with at least one geometrically defined blade, in particular a material cutting tool element. The tool element is subject to an operating parameter in the operating condition. A measuring device is provided for determination and conversion of the operation parameter into a measured signal. A first measuring device cooperates with a first tool element in the operating condition such that essentially only a first operating parameter for the first tool element may be recorded by the first measuring device.

  • Patent number: 5821432
    Abstract: A force and moment measuring device has multicomponent force measuring cells arranged in opposite pairs at either side of a force introducing platform or mounting plate, viewed in the direction of their tension/pressure sensitivity. The opposed force measuring cells are preloaded by a common preloading screw extending in the direction of their tension/pressure sensitivity and passing through the force introduction platform without friction. The opposed force measuring cells have opposed tension/pressure sensitivity orientation. The tension/pressure measuring signals resulting from a temperature change occurring in the mounting plate and/or in the common preloading screw are cancelled out by opposed measuring cells, while the measured values generated by a force acting in one direction are added together.
