Abstract
Abstract A fiber optic seal having a block with similar fiber spreading inserts and similar fiber combining inserts which terminate in rectangular facial fiber openings. The block is placed on alignment lugs and a rectangular reticle is precisely moved by a micrometer in front of the light source to illuminate the one group of fiber ends. The second group of ends in the block is observed through an observing device mounted in an angle in the housing parallel to a handle which includes a power source.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
109 words
Fiber optic seal apparatus comprising a block, first and second pathways crossed within the block, the pathways having fiber bundle receiving openings and fiber end holding openings in spaced relationship on facial areas of the block, bundle holding means connected to the block for holding an optic fiber bundle end inserted in each pathway with portions of the fibers near one end of the bundle threaded between portions of the fibers near the opposite end of the bundle in random arrangement within the block and fiber directing means mounted within the block, and facial collet means having rectangular openings for holding the ends of fibers in tight rectangular configuration.
Claim 2
Dependent Claim
109 words
Fiber optic seal apparatus comprising a block, first and second pathways crossed within the block, the pathways having fiber bundle receiving openings and fiber end holding openings in spaced relationship on facial areas of the block, bundle holding means connected to the block for holding an optic fiber bundle end inserted in each pathway with portions of the fibers near one end of the bundle threaded between portions of the fibers near the opposite end of the bundle in random arrangement within the block and fiber directing means mounted within the block, and facial collet means having rectangular openings for holding the ends of fibers in tight rectangular configuration.
Claim 3
Dependent Claim
53 words
The apparatus of claim 1 further comprising means for mounting the block in a holder with one opening of each passageway extending toward the holder, and wherein the holder has a rectangular reticle means for communicating a light source from the holder through the rectangular reticle into one facial opening in the block.
Claim 4
Dependent Claim
38 words
The fiber optic seal apparatus of claim 2 wherein the rectangular reticle and means for sliding the rectangular reticle for selectively controlling light for selective illumination of optic fiber termini in the one facial opening of the block.
Claim 5
Dependent Claim
32 words
The fiber optic seal apparatus of claim 3 wherein the sliding means comprises a micrometer connected to the means for interposing reticle mounting means for moving the reticle by turning the micrometer.
Claim 6
Dependent Claim
26 words
The fiber optic seal apparatus of claim 2 further comprising an observation adapter connected to the mounting means and an observation means mounted on the adapter.
Claim 7
Dependent Claim
42 words
The fiber optic seal apparatus of claim 5 further comprising a housing connected to the mounting means and a power source connected to the mounting means and a light mounted in the housing adjacent the reticle and connected to the power source.
Claim 8
Dependent Claim
38 words

Claim 9
Dependent Claim
62 words
The fiber optic seal apparatus of claim 1 wherein the fiber directing means comprise first and second spreading means mounted in first and second passageways near an intersection of the passageways for receiving the fiber optic bundles and for orienting fibers in the bundles in laterally spread position and wherein the spreading means have shoulders for preventing excessive insertion into the passageway.
Claim 10
Dependent Claim
16 words
The fiber optic seal of claim 8 wherein the first and second spreading means are identical.
Claim 11
Dependent Claim
44 words
The fiber optic seal apparatus of claim 8 further comprising a fiber optic bundle having a first end positioned in one of the pathways and spreading means having a medial portion extending from the block and having a second end remote from the block.
Claim 12
Dependent Claim
21 words
The fiber optic seal apparatus of claim 1 wherein the directing means comprise first and second converging portions having rectangular cross-sections.
Claim 13
Dependent Claim
14 words
The fiber optic seal apparatus of claim 11 wherein the converging portions are similar.
