Abstract: Improved means of attaching electrical connectors to miniaturized electrical components are disclosed. Flexible leads separately attached to the front of an electrical component are attached at their opposite ends to more rigid electrical connectors on the reverse side of the electrical component. The electrical connectors and the electrical component are preferably bonded together for improved stability. The resulting electrical component is typically surrounded with at least one protective covering.

Abstract: Birefringence resulting from the relative retardation of light waves propagating at different speeds through a stressed plate or coating is measured automatically by splitting a light wave emerging from the stressed plate or coating into at least two beams, filtering each beam with a filter which transmits a different wave length, transforming the light intensity from each filter into electrical signals and using the electrical signals to measure the resulting phase shift which is directly proportional to the birefringence.

Abstract: A mechanical force gauge for measuring opposed forces upon deformation of a fixed end beam. A wedge pin member is located along a neutral axis of at least one leaf member of the fixed end beam. Tensile or compressive forces are determined by measuring the change in position of a contact point located on the wedge pin member as changes in load are applied to the leaf member. This measurement is accomplished by means of a probe attached to an indicating instrument which engages the wedge pin member at the contact point. The relative distance between the wedge pin member and the probe can be adjusted initially to vary the capacity of the gauge and the angle of inclination of the wedge pin member can be adjusted to vary sensitivity of the gauge.

Abstract: A strain gage of the electrical resistance type is disclosed herein which has improved adhesive means to attaching the gage to a member under test. The adhesive is applied to the gage at the time of manufacture and includes a thermosetting adhesive composition which is substantially nontacky at room temperature, and upon heating to a first elevated temperature wets the surface of the test piece in contact therewith and when heated to a second higher temperature, is converted to the infusible, insoluble state.

Abstract: A trimming potentiometer comprising a base with a flange extending perpendicular to it and a cover that encloses the flange and is sealed to the base. Supported on the flange is an assembly comprising a post, a non-conductive plate on which an arcuate resistive path is disposed, a contact plate with a contact finger that presses against the resistive element, and a gear journaled on the shaft and releasably coupled to the plate to move the finger along the arcuate resistive path. The shaft, the plate and finger, and the gear are joined together, and a spring is provided to force the plate into engagement with the gear. The cover has a lead screw mounted in it with a head available to the outside and the threaded portion in mesh with the gear. The axial direction of the screw may be either perpendicular to the base or parallel with it.

Abstract: A trimming potentiometer including a housing having top and bottom sections. The bottom section houses a gear which has on one of its flat surfaces a laterally disposed cam for engagement with a matching cam on one surface of a contact drum which also fits within the housing. The drum has on its reverse surface an electrical contact pressed against an arcuate-shaped resistance element housed within the top section and having each of its ends connected to a conductive terminal. The gear is driven by a worm rotatably mounted in the bottom section. Rotation of the worm drives the gear, which rotates the drum, causing the electrical contact to sweep across the arcuate-shaped resistance element. The drum has a stop that engages abutment edges on the housing to limit rotation of the drum so that the electrical contact will not go beyond the arcuate limit of the resistance element, usually 270* or so. If rotation of the screw is continued after the stop engages the abutment edges at either end of the range of rotation, the gear and screw are forced out of engagement with each other by camming action between the cam on the gear and the matching cam on the drum to prevent destruction of either the gear section or the thread surface of the worm. Within the bottom section is positioned a gear spring which will flex when the gear is forced out of position against it, but will keep the gear otherwise engaged with the screw. The drum is generally circular in shape and large enough to have one of its sides ordinarily pressed against a shoulder at the bottom section. Since the drum will rotate with the gear, unless otherwise provided, the drum will encounter large frictional forces when turning against the shoulder of the section. To reduce friction a wave spring is provided between the drum and the section shoulder.
