Abstract: An improved battery plate comprises a grid or web of woven non-conductive material having lead metal or other electrically conductive material wires as some of the weft and possibly some of the warp threads. By alternately applying positive and negative active materials at laterally spaced locations across a wide web of such material and gathering portions of lead wires to form terminals, plate pairs are produced which are joined by a length of woven material of suitable strength for supporting the plates in a battery. Thus, pure lead metal wires may be used for improved electro-chemical properties, while simultaneously a great reduction in plate weight is achieved. A method of making such plates is also disclosed.

Abstract: A high fatigue slug squeeze riveting process using two clamps, one of which is a fixed position clamp, and an apparatus for carrying out the process is disclosed. A pair of panels or other items to be riveted together are clamped by upper and lower clamps and a hole is drilled through the items. Thereafter, a nonheaded rivet slug is inserted in the hole.

The lower ram stops at a predetermined position, providing a positioning stop for the rivet slug. The upper ram continues down. Since the pogo feet extend past the impinging face of the upper ram, they contact the adjacent surface of the items to be riveted prior to the upper ram contacting the rivet slug.

Abstract: A process for producing VLSI (very large scale integrated) circuits employs techniques of self-aligned gates and contacts for FET devices and self-aligned contacts for both diffused conducting lines in the substrate and polysilicon conducting lines situated on isolating field oxide formed on the substrate. Mask alignment tolerances are increased and rendered non-critical. The use of materials in successive layers having different oxidation and etch characteristics permits selective oxidation of only desired portions of the structure without need for masking, and removal of selected material from desired locations by batch removal processes again without use of masking. The process and resulting structure affords inherently self-aligned gates and contacts for FET devices and conducting lines.

Abstract: In a wheel alignment system, the error caused by run-out of the axis of a fixture that is clamped to the wheel and mounts gravity stabilized inclination sensors is corrected by continuously providing fixture axis inclination signals during rotation of the wheel through at least 360.degree. from any random starting position. Maximum and minimum comparator devices continuously receive these signals. A first adder adds the maximum and minimum signals and divides them by 2 to provide a preliminary alignment signal proportional to the actual angular inclination of the wheel axis in a selected alignment plane, and the preliminary alignment signal is subtracted from an intermediate inclination signal from the sensor that represents the inclination of the fixture axis at the wheel stopped position to provide a run-out error signal proportional to that portion of the total angular run-out of the fixture axis that is present in a selected alignment plane at the wheel stopped position.

Abstract: A machine for dehydrating food, as an aid toward preservation of food for extended periods of time. Intake air may be obtained from either the exterior of the machine or a combination of exterior and recycled air. Intake air is electrically heated and pressurized in a plenum chamber by a fan.
