摘要： The disclosed embodiments are directed to an improved automatic screw machine employing a first servomotor connected to cause rotation of a first set of tooling cams independently of the operation of a spindle drive, and a second servomotor to cause rotation of a second set of cams independently of the operation of the spindle drive, wherein a multi-axis controller controls at least the speed of the spindle drive in conjunction with at least each of the two servomotors, and where the operation of at least the two servomotors is electronically synchronized.

摘要： A breakerless ignition distributor equipped with a pair of centrifugally responsive spark retarding discs sandwiched between a pair of bearing members all held assembled to the distributor shaft by a readily adjusted clutch. Centrifugally responsive balls held captive in sets of diverging slots in the two discs are urged by calibrated springs to their inner or retracted position. The centrifugally actuated disc has a ring of peripheral openings rotating across a light beam to activate a solid state ignition circuit and is effective to retard the spark during engine starting and to advance the spark thereafter. The distributor is quickly convertible for operation either clockwise or counterclockwise.
