The present invention relates to a method and apparatus for scoring and breaking an optical fiber and, specifically, for scoring and breaking an optical fiber near a ferrule forming an end face substantially normal to the longitudinal axis of the optical fiber.

Method and apparatus for scoring and breaking an optical fiber

A unitary emitter-detector diode device for direct optical coupling to optical transmission lines as two surface oriental optical fibers on lateral surfaces of the device. The device has a p-n junction formed between a heavily doped semiconducting layer and a lightly doped semiconducting layer and means for guiding and concentrating the recombination of carriers within the diode. The feed through geometry permits transmitting in either direction from the device as well as detecting.

Bi-directional, feed through emitter-detector for optical fiber

A peripheral band is used as a load-containment device in a high-capacity, swinging bucket centrifuge rotor. The peripheral band is concavo-convex in radial cross-section such that the mid portion of the band is thinner than the edge portions to provide increased structural strength and reduced wind resistance. The rotor includes a hub and a shaped disc-like piece of sheet metal which forms the bottom of the rotor and interconnects the rotor hub with the peripheral band. The rotor bottom supports the band against gravity. The swinging buckets themselves are mounted on pivots secured to the band. In this manner, the available volume of the inside of the rotor cavity is increased.
