摘要： A piston trimmer capacitor with a nonrotating piston comprises a tube of a dielectric material (glass) externally carrying a fixed cylindrical capacitor plate. The piston is a hollow metal cup within the tube, one end of which is threadably engaged to a longitudinal lead screw to permit positioning of the piston with respect to the external plate. Two openings with flat surfaces are formed in the end of the piston. These engage flats on two guide rails of special construction rigidly affixed to a bushing in one end of the tube. The engagement of the two sets of flats effectively prevent rotation of the piston without binding or interference with the axial motion of the piston in the tube. It also provides an excellent electrical connection between bushing and piston with a minimum of resistance and inductance. The bushing with its guide rails is preferably machined from a single piece of cylindrical stock. The outside diameter of the rails is just slightly less than the inside diameter of the piston. The flats are machined and the cylindrical stock is slotted on the diameter to accommodate the lead screw and bridge at the end of the cap, which leaves two solid arcuate legs dependent from the side of each rail, which legs effectively increase the rigidity of the guide rails and their resistance to twisting under torques.

摘要： A variable electronic component having a plurality of unmounted coacting elements adaptable in particular for attachment in subminiature electronic circuits on a supporting substrate includes, at least one conductive contact means connected to one side of the circuit and adjustable means independent of and in spaced relation to said contact means for operative coaction therewith. The adjustable means has at least one support member of conductive material connected to the other side of the circuit and at least one movable means in current conducting relation with and slidably or rotatably disposed on the support member for guided movement into and out of engagement with the contact means. Means are provided to maintain the movable means in adjusted position of engagement with the contact means, and means disposed between the contact means and the movable means is provided to establish a desired impedance characteristic for said electronic component.
