Abstract: Circuit module (10) having a row of connector pins (21) and being approximately 4 mm. thick or less, and including an electrical circuit (22) connected to the connector pins (21). In prior art designs, it has not been possible to utilize a large substrate having good heat dissipation properties and, at the same time, include an attached electrical device, without exceeding the allowed maximum dimensions of the module. The present invention solves the problem by recessing an edge (17) of the substrate (11), depositing spaced-apart conductor films (26a and 26b) in the recess (16) that electrically connect with the electrical circuit (22), and soldering (31a and and 31b) the electrical device (30) to the conductor films (26a and 26b). Principal uses for the invention include digital computers and similar complex electronic devices.

Abstract: A variable resistance control comprising a variable resistance control portion and a stabilizer assembly portion. The variable resistance control portion is provided with a housing, a resistance element and a contactor supported within the housing with the contactor wipably engaging the resistance element, and an adjustment member operatively connected to the contactor and exposed on the exterior of the housing. The stabilizer assembly portion comprises a stabilizer having weight greater than the weight of the variable resistance portion and having a threaded bushing. An aperture extends through the stabilizer and the bushing and an extension shaft is rotatably received in the aperture with one end extending outwardly from the aperture cooperatively engaging the adjustable member. A U-shaped plate having a bight portion and a pair of arms secures the stabilizer to the housing.

Abstract: A variable resistance control of the rectilinear and multiturn type is provided with a contactor having a plurality of contactor paddles. The contactor paddles are wedge-shaped, are defined by a saw-tooth shaped shear line in a planar portion of the contactor, and are bent upwardly to provide flexing clearance between adjacent contactor paddles.

Abstract: A variable resistance control comprises a resilient nonconductive annular skirt sandwiched between a pair of substrates. The skirt has an arcuate section and a pair of posts interconnected by a bridge section. Each of the substrates comprises a circular portion carrying a resistance film and an extending portion provided with apertures and engaged by the posts. A driver is rotatably carried by the control and contactors are constrained to rotate with the driver wipingly engaging the resistance films. The apertures in the extending portions of the substrates are in line with the posts and the periphery of the bridge section substantially coincides with edges of the extending portions. Terminals are secured to the extending portions of the substrates and comprise a head and a tail. The head is received in an aperture and a pair of spaced fingers integral with the terminal are clinched into engagement with the head disposed between the spaced fingers.
