Abstract: A thread tapping machine for tapping female threads into a series of associated articles that are held in an associated stationary fixture includes a housing mounted for reciprocating movement toward and away from the stationary fixture. The housing is rotationally fixed. A spindle is carried by the housing for reciprocating movement therewith and for rotational movement within the housing. A shank is carried by the spindle and is configured for rotational and reciprocal movement with the spindle. The shank has a flute tap section, an elongated shank body, a transverse section opposite the flute tap and a bent section between the transverse section and the elongated body. The housing is moved toward and into contact with a first of the series of articles with the spindle rotating so that the flute tap section engages the article to form a thread therein.

Abstract: A system for guiding charged laser targets to a predetermined focal spot of a laser along generally arbitrary, and especially horizontal, directions which comprises a series of electrostatic sensors which provide inputs to a computer for real time calculation of position, velocity, and direction of the target along an initial injection trajectory, and a set of electrostatic deflection means, energized according to a calculated output of said computer, to change the target trajectory to intercept the focal spot of the laser which is triggered so as to illuminate the target of the focal spot.
