Prin uppe: booc section is iadzicuced as a cylinder from a nylon
zvinio:ced vinyl laminated racerial, iú oz. per yard. This unit is
hcui süüleci and includes a seal ring as supplied by the manipulator
manufacture: at one end and a v 7/8 inch I.D. x 2 inch wide x 15 sa.
üluminum support band at the other. Since the support band is located
around the aüimuth pulleys it serves a dual purpose; it not only pro-
vices û clamping surface for the lower section but also protects the
boot from being pinched or cut by the üzimuch pulleys.
Tic cover boot section is fabricated from a nylon reinforced
vinyl cial, 12 oz. per yard, which has been accordion-pleated. >
This unic contains t1:10 small aluminum bands 1/2 inch wide x 7 1/2
inches and 7 5/8 inches x 1/16 inch thick fashioned as a darning hoop

at one end and a sprayed urethane gauntlet at the other. The
darning hoop contains a polyvinylidene chloride plastic diaphram to
protect the unit from interior contamination until it is installed
on the manipulator. A 6 3/4 inch to 7 1/4 inch I.D. ritig clamp made
of 1/8 inch diameter wire is used as the fastening device for at-
1
For installation, the lower section is bagged as a package and
inserted into the cell through regular access ports where the bag
is opened and the boot section is slipped through the ring clamp.
The unit is then lifted up to the manipulator where the diaphram is
ruptured and the boot section is placed in position. Figure 1
shows the boot section just prior to clamping the two units into final
position. When the ring clamp is mated to the aluminum band section
of the upper unit, th: clamp is released and the installation is
complete.
With this booting arrangement it is no longer necessary to remove
a manipulator to make a gauntlet change and time required to replace
a damaged gauntlet has been reduced from approximately three hours to
about fifteen minutes.
An additional advantage of the two-piece boot has been realized
in a substantial reduction of personnel radiation exposure for the
manipulator maintenance crew.
