A cord reel device (1) for connecting a signal source (A) to a remote device (B, C) comprises a spool (2) rotatable on an arbor (18), the spool (2) having an inner chamber (6) and an outer trough (8). A retractable cord (10) is removably held in the trough (8). A spring (220) for urging the rotation of the spool (2) in a direction to retract the cord (10) is held in the inner chamber (6). The inner cable (24) is electrically connected to the retractable cord (10). The cord reel (1) of the invention may preferably include EMI-RFI shielding (112), and may find particular utility in applications requiring a substantially miniature cord reel, such as with a cellular telephone or the like.

An apparatus for practicing the process of claim 3 whereby volatile vapors are eliminated from the ullage of tanks comprising (a) an airtight flexible bladder determined to be capable of inertly holding the said volatile vapors forming inflammable or hazardous material; (b) means of structurally supporting and protecting said bladder including setting same inside another protective tank; (c) means of filling said flexible bladder without compromising its airtightness, including use of a temporary tank fluidly one-way connected to said airtight flexible bladder, said temporary tank being filled and drained into said flexible bladder until a preset volume is attained, without compromising its airtightness; (d) means of suctioning off said inflammable or hazardous material from the said flexible bladder when required; and whereby said bladder extends and contracts only to the extent of its contents thus eliminating any ullage space conducive to volatile vapor formation. 5. An apparatus for stripping an inflammable or hazardous material of its inflammability or hazardous abilities when one or more trigger events occur, including a vehicular crash or collision, comprising (a) a tank for said inflammable or hazardous material being expansible for providing sufficient extra capacity to accommodate volume changes when a disabler is emptied into it; (b) a tank for said disabler predetermined to be able to chemically interact and interfere with and alter said inflammable or hazardous material such that the latter is substantially and appreciably stripped of its inflammability or hazardous abilities; (c) fluid one-way connections from said disabler tank to said inflammable or hazardous material tank; (d) means of and sensors for detecting the occurrence of said trigger events; (e) means of rapidly emptying the disabler tank into said inflammable or hazardous material tank on the occurrence of said trigger events; (f) means of rapidly interacting said disabler with said inflammable or hazardous material; and whereby said inflammable or hazardous material is disabled and substantially and appreciably stripped of its inflammability or hazardous abilities, which abilities are otherwise manifestable on the occurrence of said trigger events. 6. A vessel wherein is set up the apparatus of claim 5 and providing said tank for said inflammable or hazardous material being utilized for the needs of said vessel or carried as a transported commodity, said tank having sufficient extra capacity to accommodate volume changes when said disabler is emptied into it. 7. An apparatus of claim 5 wherein said inflammable or hazardous material includes a hydrocarbon and the disabler comprises joint and several use of (a) a saponifying agent (b) a soap (c) a detergent. 8. An apparatus of claim 5 wherein said inflammable or hazardous material includes germs and the disabler includes an appropriate germicide, whereby dangers posed to the health and safety of people, animals and the environment by such hazards are curtailed. 9. An apparatus according to claim 5 wherein said disabler is rapidly interacted with said inflammable or hazardous material by means of a perforated pipe grid connected to the disabler tank and laid inside said inflammable or hazardous material tank. 10. An apparatus accordi ng to claim 5 wherein said disabler is rapidly interacted with said inflammable or hazardous material by means of at least one strategically placed nozzle with one-way valve, connected to the disabler tank and extending through said inflammable or hazardous material tank wall. 11. An apparatus of claim 5 further including means for eliminating the volatile vapors in the ullage space of rigid wall tanks containing certain vapor-forming inflammable or hazardous material comprising (a) an airtight flexible bladder, substituting said tank for said inflammable or hazardous material, and determined to be capable of inertly holding the said inflammable or hazardous material, said bladder having sufficient extra capacity to accommodate volume changes when a disabler is emptied into it; (b) means of structurally supporting and protecting said bladder including setting same inside another protective tank; (c) means of filling said flexible bladder without compromising its airtightness, including use of a temporary tank fluidly one-way connected to said airtight flexible bladder, said temporary tank being filled and drained into said flexible bladder until a preset volume is attained, without compromising its airtightness; (d) means of suctioning off the said inflammable or hazardous material from the said flexible bladder when required; and whereby said bladder extends and contracts only to the extent of its contents thus eliminating any ullage space conducive to volatile vapor formation. 12. A vessel wherein is set up the apparatus of claim 11 and providing said airtight flexible bladder holding said inflammable or hazardous material being utilized by said vessel or carried as a transported commodity. 13. An apparatus of claim 11 wherein said disabler is rapidly interacted with said inflammable or hazardous material by means of at least one strategically placed dispersion stem extending substantially into said flexible bladder, said dispersion stem having nozzle buds also strategically placed to maximize said interaction. 14. An apparatus of claim 11 wherein said inflammable or hazardous material includes a hydrocarbon and said disabler comprises joint and several use of (a) a saponifying agent (b) a soap (c) a detergent. 15. An apparatus of claim 11 wherein said inflammable or hazardous material includes germs and the said disabler includes an appropriate germicide, whereby dangers posed to the health and safety of people, animals and the environment by such hazards are curtailed.
