A tile spacing tool is disclosed herein that spans a gap between tile rows where the gap is sized to receive a decorative insert or the like. The spacing tool spans the gap and transfers the weight of the upper tile rows across the gap to the lower tile rows, which are supported by a floor or ledge. As a result, the entire wall can be built including the decorative insert without waiting for the bottom tile rows to dry to support the weight of the tile rows above the decorative insert.

A feeler gauge includes multiple feeler blades and an optical sensor. Each of the multiple feeler blades rotates about an axis between a measuring position and a non-measuring position. Each of the multiple feeler blades includes a measurement portion configured to be inserted into a gap to be measured and a proximal end having an indication of thickness of the respective feeler blade thereon. The optical sensor optically determines one or more of the multiple feeler blades that are deployed in the measuring position from the respective indications of thickness of each of the one or more feeler blades.

This disclosure relates to methods and tools for calibrating a camera-based three-dimensional optical metrology system such as that used for non-contact measurement of strain in a materials test system. A tool is provided which holds a calibration plate within a test space of a load frame of a materials testing device. The tool includes a spindle which rotates around a rotational axis to a series of detent rotational positions. The spindle engages the calibration plate by a bearing configuration which allows the tilt angle of the calibration plate to be varied. The rotation of the spindle and the variation of the tilt angle provides for two degrees of freedom of movement within the test space. The resulting sequence of calibration plate positions is systematic and repeatable.

A depth gauge is provided that is configured to be removably coupled to a tool. The depth gauge having a gauge body, a coupling means to removably couple the gauge body to the tool and a fiducial on the gauge body whereby the fiducial signifies a distance between the fiducial and a portion of the tool. In some embodiments, the coupling means comprises a magnet. In some embodiments, the tool is a wire stripper whereby when the wire stripper is actuated on a coated wire, the wire stripper cuts a portion of the wire coating equal to the distance defined by the fiducial. In some embodiments, the fiducial comprises an abutment protruding from the gauge body. In some embodiments, the depth gauge has multiple fiducials and the gauge body and the fiducials are formed as one piece.

A device is for identifying glove-port positions to be mounted on a panel supported by a glovebox structure which defines a closed chamber enabling an operator to perform handling operations while being isolated from the chamber. The device includes a base, structure for attaching this base to the glovebox structure, and at least one template supported by this base while being movable with respect to this base, in order to be able to occupy different positions with respect to this base. Each template includes an opening which can receive a glove port. The device also includes structure for locking each template in position with respect to the base.

An alignment gauge includes a generally u-shaped main body and an alignment member extending therefrom. The alignment gauge is configured to be positioned on the frame of a cabinet during installation of one or more attached components, such as attachment of a pair of doors to a refrigerator cabinet. Specifically, the alignment gauge may be positioned so that the alignment member establishes a proper spacing for the attached components.
