  • Multi-functional table
    Patent number: 4903614
    Abstract: A multi-functional table of adjustable height has concealed supplementary legs capable of being swung downwardly to effectively extend the lengths of the four main legs of the table. The supplementary legs are concealed within housings that extend between the lower extremities of adjacent main legs. A release mechanism, operable from above the housings, controls the release of the supplementary legs. The deployed supplementary legs are secured by an upward sliding motion.

  • Method of making a high voltage dynamoelectric machine with selectively increased coil turn-to-turn insulation strength
    Patent number: 4724600
    Abstract: Multiple turn coils are arranged with turn insulation around individual turns, group insulation around each of a plurality of groups of turns, and ground insulation around the entire coil half. This arrangement protects against a potential discharge between turns upon occurrence of a steep front impulse voltage.
