Positioning apparatus for presenting a sample for electromagnetic analysis comprises a flexible, resilient, generally cylindrical, open-ended inner sleeve member having a lengthwise through slit, such that the effective diameter thereof is adjustable over a predetermined range in response to radially inward compression thereof. An elongate constricting assembly surroundingly engages and selectively applies radially inward compression to the inner sleeve member. The constricting assembly comprises a pair of generally rigid, cylindrical axially spaced gripping members and a plurality of resilient, helical members coupled intermediate the gripping members. The helical members are responsive to relative rotation of the gripping members in a first direction for applying radially inward compression to the inner sleeve member, and responsive to relative rotation of the gripping members in an opposite direction for releasing radially inward compression on the inner sleeve member.

Positioning device for presenting samples for electromagnetic analysis

Lateral ears of a terminal strap are bent sharply upward to form sidewalls spaced apart by the width of the strap, openings in the sidewalls overlapping arcuate edge portions of an annular flange of a threaded nut to loosely captivate the nut in position over a hole in the strap for cooperation with a threaded post projecting through the hole upon attachment of the breaker to a panelboard. Upper edges of the sidewall openings are abutted by the flange, and a frustoconical rear surface of the nut is engaged by the thread post upon installation to automatically align the nut and post.
