Abstract
Abstract The disclosure relates to a flexible airtight stranded wire for electrical interconnection between chambers wherein it is necessary that gases do not travel between chambers. The wire is formed from standard stranded wire, a short length of stranded or unstranded wire is tightly wound around one section of the wire and the wound length of wire is soldered to the stranded wire the solder passing into and entirely across the stranded wire to provide a gas tight seal therethrough. The soldered wire is then placed in a mold and stretched whereupon insulation is molded thereon, the area over the wound length of wire and solder having a greater cross-section than the remainder of the wire. The wire is secured in a bulkhead, the insulation making an airtight seal therewith.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
An airtight stranded wire which comprises a. a stranded wire b. an annular member surrounding a portion of said wire in intimate contact therewith to form a bump thereon, c. a continuous wall of solder substantially normal to the axis of said wire extending between and around the strands of said wire within the area defined by the annular member to proviDe an airtight seal along the axis of said wire, and d. insulation means surrounding said wire and said annular member and bonded thereto, e. said insulation means including insulation of predetermined first cross-section over said annular member and insulation of predetermined second cross-section less than said first crosssection along the remainder of said wire.
Claim 2
Dependent Claim
116 words
An airtight stranded wire which comprises a. a stranded wire b. an annular member surrounding a portion of said wire in intimate contact therewith to form a bump thereon, c. a continuous wall of solder substantially normal to the axis of said wire extending between and around the strands of said wire within the area defined by the annular member to proviDe an airtight seal along the axis of said wire, and d. insulation means surrounding said wire and said annular member and bonded thereto, e. said insulation means including insulation of predetermined first cross-section over said annular member and insulation of predetermined second cross-section less than said first crosssection along the remainder of said wire.
Claim 3
Dependent Claim
29 words
An airtight stranded wire as set forth in claim 1 wherein said annular member is a turn of wire in a one plane substantially normal to said stranded wire.
Claim 4
Dependent Claim
88 words
Structure for providing an airtight passageway for a flexible conductor passing through an opening in a wall, wherein the conductor is provided with an annular protuberance thereabout, insulation bonded to the conductor and protuberance, the portion of the insulation about the protuberance being of greater diameter than that about the remaining portion of the conductor and that of the opening, and means bearing against one end of said portion of the insulation about the protuberance for compressing it against the wall about said opening to form a seal.
Claim 5
Dependent Claim
88 words
Structure for providing an airtight passageway for a flexible conductor passing through an opening in a wall, wherein the conductor is provided with an annular protuberance thereabout, insulation bonded to the conductor and protuberance, the portion of the insulation about the protuberance being of greater diameter than that about the remaining portion of the conductor and that of the opening, and means bearing against one end of said portion of the insulation about the protuberance for compressing it against the wall about said opening to form a seal.
Claim 6
Dependent Claim
24 words
Structure according to claim 3 wherein the conductor is a flexible stranded wire and the protuberance is an annular loop soldered to the wire.
Claim 7
Dependent Claim
33 words
Structure according to claim 3 wherein the conductor is a flexible stranded wire with the interstices between the strands within the area encompassed by the protuberance filled by a solid wall of solder.
Claim 8
Dependent Claim
13 words
Structure according to claim 5 wherein the protuberance is soldered to the wire.
Claim 9
Dependent Claim
23 words
Structure according to claim 5 wherein the protuberance is a single turn of wire in a single plane normal to the wire axis.
Claim 10
Dependent Claim
13 words
Structure according to claim 3 wherein the protuberance is soldered to the wire.
Claim 11
Dependent Claim
25 words
Structure according to claim 8 wherein the protuberance is a single turn of wire in a single plane normal to the axis of the wire.
