Cryogenic Coax Cable Stripping

      A method for stripping small coaxial cable is disclosed which
uses the freezing effect of a liquid nitrogen stream to separate the
wire insulation from the conductors leads without damaging the
conductors.

      This invention makes use of the cooling effect of a liquid
nitrogen stream to solidify the portion of the insulation that has to
be removed from the coaxial cable.

      The cable is held and guided by the wire guide (1).  The cable
also protrudes past the wire clamp (2).

      At 90 deg.  to the wire guide (1) are two slide mechanisms (5
and 6) that can travel in opposite direction to each other and carry
the cable stripping blades (4).  This whole assembly can also move in
the east/west direction when the stripping action takes place.  The
stripping length of the cable is determined by the protrusion of the
wire/cable (3) from the wire clamp (2).  In line with the liquid
nitrogen feed (7) is a vacuum tubing (6) to control the direction and
the amplitude of the cryogenic stream.

The procedure is described as follows (Fig. 1):

    The coax cable is in place and clamp (2) closed.  Slides (5 and
    6) retracted.

    Strip jaws (4) move forward on slides (5 and 6) to secure a grip
    into the insulating jacket of the coaxial cable.

    The cooling stream and vacuum are turned on and timed.

    Upon time-out the strip jaws (4) are moved away from the wire
    clamp (2) thus removing the portion of the cable jacket that was
    exposed to the liquid nitrogen stream and thus hardened to a
    bri...
