Abstract: A multi-level printed circuit board with at least two levels of circuitry. A substrate has a first level of circuitry, an insulating covering or layer over the entire surface of the substrate and the circuitry except in first predetermined areas, a second level of circuitry is formed over said insulating covering or layer and metallurgically bonded to form electrically conductive joints at the predetermined uncovered areas with the first level of circuitry.

Abstract: A liquid separating vessel which comprises an interior volume, a portion of which is taken up by a conduit is disclosed. The conduit extends from the top of the vessel to the bottom of the vessel. The conduit is defined between a portion of the sidewall of the vessel and a conduit-defining baffle. The baffle may be removed for easy cleaning. Structure is provided for preventing overflow when the vessel is completely filled with liquid and tilted.

Abstract: Prefabricated fingers suitable for mounting on a printed circuit board for use in conjunction with card edge connectors are provided on a lengthwise strip which may be cut to the desired size to correspond with the number of fingers which are to be mounted on the board. The strip, which may be formed in a roll, includes a pair of parallel carriers. The fingers extend between and are integrally formed with the carriers and are spaced along the lengths thereof and in substantially coplanar relationship therewith. After severing one of the carriers, the resulting free ends of the fingers may be aligned in overlapping relation with the circuit conductor ends to which the fingers are to be joined.
