Abstract
Abstract This disclosure relates to a fully automated, electro-mechanical system designed to apply a plastic coating to individual flash bulbs and then assemble them into fully tested flash cube assemblies, each containing four bulbs. The system essentially is made up of separate subsystems: fluid transfer, coating, and cube module. These subsystems are mounted on a system conveyor chassis which also contains monitoring devices to check conditions of the flash bulbs.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
88 words
A flash cube assembly system for assembling flash bulbs into tested cube assemblies, said flash bulbs containing a zirconium shredding, comprising: means for applying a plastic coating to said flash bulbs; means for conveying uncoated flash bulbs to said applying means; means coupled to said applying means for assembling the coated flash bulb into flash cube assemblies each containing four coated flash bulbs; and a zirconium photocell detector for sensing the zirconium shredding inside said flash bulbs to ascertain whether it is uniformly distributed throughout said flash bulb.
Claim 2
Dependent Claim
88 words
A flash cube assembly system for assembling flash bulbs into tested cube assemblies, said flash bulbs containing a zirconium shredding, comprising: means for applying a plastic coating to said flash bulbs; means for conveying uncoated flash bulbs to said applying means; means coupled to said applying means for assembling the coated flash bulb into flash cube assemblies each containing four coated flash bulbs; and a zirconium photocell detector for sensing the zirconium shredding inside said flash bulbs to ascertain whether it is uniformly distributed throughout said flash bulb.
Claim 3
Dependent Claim
23 words
A flash cube assembly system according to claim 1 further comprising: a blue dot detector photocell for detecting leakage in said flash bulbs.
Claim 4
Dependent Claim
69 words
A flash cube assembly system according to claim 1 wherein said conveying means comprises: means for storing uncoated and untested flash bulbs; at least one liquid filled tank in which the uncoated and untested flash bulbs float; means for feeding said uncoated and untested flash bulbs from said storing means to said tank; and means for transferring said uncoated and untested bulbs from said tank to said assembly means.
Claim 5
Dependent Claim
