Abstract: An anti-sway trailer hitch connection is provided for use between a towing vehicle and a trailer and includes structure whereby slight left and right lateral movement of the forward end of the towing vehicle will not be translated into right and left lateral movement, respectively, of the forward end of the trailer, and thereby eliminates the tendency of a trailer to sway back and forth while a towing vehicle changes lanes on a highway or is acted on by cross-wind gusts from the passing of a large vehicle.

Abstract: A circuit board fabrication apparatus and method having a vibratory feeder tray is disclosed. The feeder tray is preferably of low mass and horizontally-disposed and has multiple grooves which closely fit electronic parts, and hollowed-out bottom portions, generally below the rails separating the grooves. The hollow portions significantly contribute to low mass. Almost 50% of the mass of the tray's top plate may be removed. The parts are picked up one at a time and placed at precise positions on circuit board substrates by the rotating nozzles of a pick-and-place turret. An electromagnetic coil operating below the grooves of the feeder tray smoothly and continuously advances the parts in the grooves to the region in which they are picked up by the nozzles. Additionally, a slider table supporting the vibratory feeder tray positions each groove of the feeder tray in turn at the uptake point of the turret.

Abstract: An add-on card which has a flat surface on the top side on which a plastic quad flat pack integrated circuit packaged integrated circuit can be soldered upon. The other side of the add-on card has downwardly protruding pins that can plug into a pin grid array integrated circuit socket. A method of manufacturing a add-on card whereby bonding pads are disposed on one side of the add-on card and pins are disposed on the other side of the add-on card.
