Abstract
A motion transmitting mechanism, for use as a sample manipulating device or wobble stick, is provided for transmitting manual movements through the wall of a vacuum vessel. The mechanism includes a central mounting flange for securing the mechanism in vacuum sealing arrangement with the vacuum vessel through a suitable orifice formed in the wall thereof. A spherical ball joint is moveably journalled within the mounting flange to enable the mechanism to be moved angularly relative to an axis perpendicular to the vacuum vessel wall throughout a predetermined range of limited angular displacement. A coaxial shaft assembly comprises an outer tube and a central shaft, the assembly being axially slideable through a central opening of the ball joint means to provide axial movements within the vacuum vessel throughout a predetermined range of limited axial displacement. A rotation imparting structure is connected to the coaxial shaft assembly for imparting unrestricted rotational movement to the central shaft relative to the outer tube. Extensible vacuum sealing baffles extend from the flange on the vacuum side of the mechanism and are connected to the rotation mechanism. The sealing baffles are provided for vacuum sealing of the interior of the coaxial shaft assembly. Axial displacement of the central shaft relative to the outer tube provides control for pincers which may be installed at the inner end of the mechanism.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
