A New, Versatile Vacuum Quick-Seal and Vacuum Lock *
0. D. Matlock
Late in 1963, a decision is made to put micro-wave experiments
into the E.P.A. facility, which has a main vacuum chamber approximately
4' X 9'..with numerous seals. At that time, many of our seals were made
minis...
of nylon and teflon, materials not compatible with micro-waves. This
problem along with others of compactness, ease of assembly, thermal

a
conductivity, and gas trapping, led to the development or the all-metal
quick seal. Figure 1 shows this in cross section assemblea to s
vacuum all. Basic pass-thru units have been developed in 3/8", 1/2",
and 3/4" sizes. Requirements for assembly are a 5/64" Allen wrench,
which fits all three sizes, and a drilled hole 1/8" larger thar pass-
thru sizes (3/8" takes a 1/2" hole, etc.). The method and sequence
of assembly can be followed by referring to Fig. 2, the assembly of
parts being from right to left. The body "0" ring is inserted into the
jack plate grouve, and the two are slipped over the finger end of the
body. The body is then inserted into the vacuum wall drilled hole, after
which the slotted sleeve is inserted into the body bore; the sleeve
expands: the fingers and holds them in position to grip the edge of the
hole, (each finger lip in expanded position is .020 to .025 thousandths

time is less than five minutes. It should be noted that the jack plate
is floating and can accommodate several degrees of tilt and over one
quarter inch variation in wall thickness. Note that the slotted sleeve
allows good pumping to the seals and cuts thermal conductivity.
The bore
of the body without the sleeve always being a sixteenth inch larger
allows easy assembly over protruding lines, leads, and shafts. Accessory
parts have been developed as follows:
l. a nylon jack plate for use on concave or convex surfaces
2 - a ball adapter that gives plus or minus 8° angle motion with full rotation
3 - nylon insulator sleeves for other than micro-wave applications
4 - size adapters for reduced shaft sizes, typically the 5/16", 1/4"
3/16", and 1/8" used in the 3/8" seal
5 - solid core wire connectors used with nylon sleeves
6. thin wall adapters for 1/16" to 1/2" walls
For all sizes there are two lengths: a short one that fits walls of 1/2"
to 3/4" thickness, and a long one that fits walls of 3/4" to 1 1/16" thickness.
For even thicker walls a special tool grooves the hole so that the finger
lips can catch the edge of the groove in the same manner as the co
the edge of a hole. Using the groove cutter, a special drill, and a
"quick valve" (fig. 4), insertions can be made into systems under vacuum.
Figure 3 shows an exploded view of the "quick valve", which is a
compact integral valve, lock, and pump out system. The parts shown are
for a 3/8" pass-thru. Figure 4 shows, in cross section, the assembly of
the valve to a quick seal with a wire probe ready in lock for insertion.
The assembly is made by taking the gland and nut from the seal and inserting
the nose piece of the valve using the valve nut for the connection. Standard.
vacuum lock procedure is useå to make insertions; for retractions or pull. :
outs, the pump-down valve doubles as a let-down valve. This is accomplished

by simply pulling the vacuum hose loose from the nipple and leiting
· the lock down to air by backing the valve out. After an insertion
is made, the valve nut can be tightened to isolate the valve volume,
thus avoiding possible virtual leaks from this source. This is é spccial
feature of the assembly. Figure 5 shows a 3/8" rod thru the assembly.
The small over-all size of the complete assembly could be of special
interest in applications where space is a problem.
