The coupler is interconnected with the plunger and includes a spring for imparting to the plunger a plug gage expanding force. The coupler also includes a slotted lever to which the plunger is connected and which is manually actuated to retract the plunger for contracting the plug gage preparatory to its insertion into a bore to be measured in a workpiece.

Abstract: There is disclosed in the present application, a gage particularly adapted to measuring the effective interior diameter of a workpiece or part which is too flexible to be measured at separated points of its internal diameter. Such parts, which may be of metal or plastic, include thin walled containers, the skins of cylindrical drums or shields and similar articles which have interior diameters designed to be closely fitted to rigid frames at assembly. The present gage is formed to restrain the part against distortion by forces incident to measuring, which would otherwise cause the part to become narrower in the direction perpendicular to that of the measuring force and would be the source of substantial error in gaging the effective interior dimension of the undistorted part for purposes of assembly. In addition, the present gage includes a provision for automatically translating the circumference measurement of the part into the effective diameter of the part in undistorted condition.

Abstract: The gage assembly of the present application includes a gage head detachably mountable on an amplifying and indicating mechanism for providing a graduated indication of any deviation in the size of an internal enlargement or groove in a bore in a workpiece. The gage head includes a pair of opposed radially slidable blades urged outwardly by a spring force exerted on a tapered plunger by a spring forming a part of the amplifying and indicating mechanism. The outward extension of the blades, which are sized and shaped to enter the groove in the workpiece, is coupled to the amplifying and indicating mechanism by the axial displacement of the plunger and displayed on an indicator dial forming a part of the mechanism. The gage head is centralized in the bore by a pilot adjacent the blades, which aligns the head with the axis of the bore.

Abstract: There is disclosed in the present application a method and apparatus for treating variable batches of moist dielectric materials by the application of radio frequency energy which reduces the moisture content. According to the present method and by the use of the present apparatus, full power or another pre-determined power level from a radio frequency power source is maintained on the load by an electro-mechanical adjusting device which incrementally reduces the coupling between the source and the load until the boiling point of water is reached. After the boiling point is reached the coupling is incrementally increased to reach a pre-determined moisture content in the material being treated. There is included in the present apparatus, means for counting the number of discrete coupling adjustments in both directions.
