Abstract: A snatch block has a stationary first cheek and a movable second cheek that is slidable in its respective plane relative to the stationary first cheek. In a closed position, the second cheek connects with a crown jutting from the first cheek, thereby closing off a swallow of the snatch block. In an open position, an access gap opens into the swallow between the movable second cheek and the crown, thus enabling loading of a rope into the swallow. A locking mechanism with slide latches or rocker arms normally locks the second cheek in the closed position, and requires simultaneous actuation of two discretely separate releases to unlock the second cheek. The second cheek is biased into the open position, providing overt visual indication of any failed latching attempt. A seamlessly integral stud protrudes from the crown to rotatably support a swivel eye thereon.

Abstract: An improved system for handling delicate linear media and in particular to a method and apparatus for winding delicate linear media such as superconducting wire or tape or optical fibers onto a spool or former. A combination of direct closed loop control and media routing design facilitates the handling of the delicate media without causing damage. The axial tension in the linear media may be closely controlled during winding by means of feedback control loop using tension measurements to control the rotation speeds of the wind-from and wind-to spools. Further, during winding, the delicate linear media is only exposed to large radius bends with no reverse bending. Finally, output devices and features, commercial or otherwise, made possible by delicate linear media handling are revealed. This includes advanced SC devices and features.
