Abstract: A fiber optic mechanical splice for splicing input and output optical fiber. The splice includes a capillary tube for enclosing fiber ends of the input and output optical fiber cables, two metallic cable-splice bridging flanges for insertion onto the input and output optical fiber cable jackets, a first metallic crimping tube, a second metallic crimping tube, a first protection tube, a second protection tube, and polyurethane tape. The fibers extending from the input and output optical fibers can be frustoconically inserted into a corresponding bridging flange. The crimping tubes enclose corresponding cable ends and bridging flanges. The first protection tube encloses the crimping tubes, while the second protection tube encloses the first protection tube and the tape is disposed over the second protection tube, the bridging flanges, and the crimping tubes.

Abstract: A method and apparatus for assembling a fiber optic splice is provided. A first optical fiber end is inserted into a first clamp of the apparatus and a second optical fiber end is inserted into a second clamp of the apparatus. Situated between the first clamp and the second clamp is a curing chamber comprising a capillary tube containing resin and an ultra violet light. The first clamp moves a first distance, based on a first measured strain, towards the curing chamber. The second clamp is moved a second distance, based on a second measured strain, towards the curing chamber. The first clamp is then moved a third distance, based on a third measured strain, towards the curing chamber. The ultraviolet light is activated to cure the resin in the capillary tube.

Abstract: A tensioning device for a sheet of material that includes a first ring with protrusions, a second ring, and a shaft. The first ring and the second ring are positioned such that the sheet of material can be clamped between the first ring and the second ring. The shaft has an outer surface, the outer surface includes a spiral race such that the protrusions of the first ring follow the spiral race, allowing the first ring and the second ring to displace linearly causing the sheet of material to be stretched. The spiral race includes a plurality of notches that correspond to the protrusions.

Abstract: An impedance tube and sample tube holder that includes a hollow tube, a first tube, a second tube, and a spool. The hollow tube has two halves which are detachable and can hold spacers and a sample. The first tube includes a first tube speaker end and a first tube spool end. The first tube has a speaker disposed at the first tube speaker end and microphones. The second tube includes an anechoic terminator tube end and a second tube spool tube. The second tube has microphones and an anechoic terminator at the anechoic terminator tube end. The spool holds the hollow tube with the spacers and the sample. The spool is attachable to the first tube spool end and the second tube spool end such that the sample is perpendicularly orientated to an incoming sound wave produced by the speaker.
