Abstract
Abstract A portable device for coupling optical fibers consisting of an insulative block so designed as to allow a number of optical fibers to come together, a piezoelectric generating means secured to the block and connected to the piezoelectric generator so that optical fibers will be brought together at a point between the electrodes. Electricity generated causes an arc across the electrodes which generates sufficient heat to join the optical fibers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
76 words
A portable optical fiber coupling device comprising: a block of solid insulative material; a passage for optical fiber located along the central axis of said block; piezoelectric means for generating an electrical potential difference fixed to said block; a pair of electrodes positioned in the block adjacent said passage and connected to said means for generating whereby a potential created by the generating means will cause an arc between said electrodes thereby coupling fibers positioned therebetween.
Claim 2
Dependent Claim
76 words
A portable optical fiber coupling device comprising: a block of solid insulative material; a passage for optical fiber located along the central axis of said block; piezoelectric means for generating an electrical potential difference fixed to said block; a pair of electrodes positioned in the block adjacent said passage and connected to said means for generating whereby a potential created by the generating means will cause an arc between said electrodes thereby coupling fibers positioned therebetween.
Claim 3
Dependent Claim
24 words
A portable optical fiber coupling device according to claim 1 including a slot in said block extending to the passage for removing coupled fibers.
Claim 4
Dependent Claim
30 words
A portable optical fiber coupling device according to claim 1 wherein each end of said passage is conically shaped having its apex connected to the passage at the said electrodes.
Claim 5
Dependent Claim
22 words
A portable optical fiber coupling device according to claim 1 wherein said block is in two parts mounted in a hinged relationship.
Claim 6
Dependent Claim
25 words
A portable optical fiber coupling device according to claim 4 including a plurality of matched grooves in the abutting faces of each of said parts.
