Abstract: Presently available transducer systems provide analog electrical outputs portional to the linear displacement of an active element from the surface being measured. However, use requires that all or part of the surface be conductive. The present cartridge permits use of these transducers on any surface, conductive or not. It includes a tubular casing receiving both an active element portion of the transducer and a plunger formed of a conductive material. The plunger is reciprocally mounted with a compression spring normally urging it outwardly so that its tip end can contact and follow the surface to be measured. A set screw arrangement limits the plunger reciprocation. The length of the received portion of the transducer is precisely adjustable so that its active element can be disposed a precise spaced distance from the plunger when it is spring-pressed to its limit. As the plunger tip rides the surface being sensed its inward motion is limited by contact with the transducer end wall.

Abstract: A set of direct-reading sine bar gages has been provided in which each of the gage elements is marked with a number corresponding to the associated angle of elevation of the sine bar when that particular element is disposed beneath the sine bar. Accordingly, when the technician is seeking to elevate the sine bar to a particular angle the technician needs only to inspect the various gage elements to determine which of them is marked with a number corresponding to the angle which he desires. A carrying tray holds each of a predetermined number of gage elements forming the set. The tray includes a base of predetermined thickness with openings formed into the base to snugly receive each of the gage elements of the set. Vent openings form flow passages between the first named openings and the surrounds. When the elements are disposed within their respective openings, the vents prevent the gage elements from being locked by vacuum within their respective openings.
