Abstract: An apparatus for fusion splicing optical fibers has one rotatable clamp mechanism that is manually operated, a second rotatable clamp mechanism that is operated by a motor and a twist preventing means removably coupled to the apparatus with an arm member. A rapid fine adjustment of the alignment of the polarization maintaining optical fibers can be made.

Abstract: A method of attaching a slide fastener to a garment having a slotted closure opening of a given length is disclosed. Rows of fastener elements, carried on and along confronting longitudinal edges of a pair of stringer tapes are interengaged to couple the same. The stringer tapes are longer than the closure opening. A slider is mounted onto the interengaged rows of fastener elements at their lower ends. The rows of fastener elements are interengaged over their entire length except for a region of disengagement resulting from the placement of a slider and located thereat. The garment is turned inside out. The coupled stringer tapes are placed onto the garment in such a manner that the outer surfaces of the coupled stringer tapes are mated with opposed inner marginal portions of the closure opening, with the interengaged rows of fastener elements in alignment with the closure opening, and with the slider disposed downwardly of the lower end of the closure opening.
