Abstract: A solid state computer circuit system is provided that senses the state of the ignition switch, setting a lock out circuit to prevent the car from being started if a hidden switch (or other enabling circuit) is not activated. There is a solid state timing circuit locking out the ignition system automatically after a predetermined time when the ignition switch is turned off (typically thirty seconds). The system is actuated with a hidden switch (or an electronic device like a garage door opener or a digital key pad with an alarm circuit sounding an alarm if the wrong code is input or a foreign item is used in an effort to wrongfully enable the basic system circuit).

Abstract: An apparatus for use in continuously assembling joinable ring shanks and ring settings into a corresponding unitary jewelry type ring comprising supporting means; advancing means operatively connected to the supporting means including at least one work holding means which removably receives a ring setting and ring shank for successively and incrementally advancing the work holding means, as well as ring shank and setting, from at least a loading station to a plurality of discrete working stations, including at least a ring shank testing station, and a bonding station, ring shank testing means located at the ring shank testing station for accurately testing for the presence and correct alignment of the ring shank with respect to the corresponding ring setting in the work holding means; and bonding means situated at the bonding station for selectively bonding the aligned jewelry ring.
