Abstract
Abstract A small and lightweight rapid gas inflating apparatus for inflating a paraglider with gas having a minimum of temperature and moisture content. A generated propellant gas is passed through a baffle plate, bed of charcoal for reduction in water vapor content, then radially dispersed through a coolant of ammonium carbonate and passed through a gas filtering anhydros body for absorption of water before being deflectively delivered in the parawing of the paraglider.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
362 words
In an inflating apparatus for an inflatable device having longitudinally spaced mounting brackets for securing a gas generating tube in a predetermined flexible material portion of said inflatable device, a centrally apertured Head cap secured to the rearmost mounting bracket and containing a rearmost end portion of said tube, an igniter in said tube rearmost end portion adjacent said head cap, said igniter being fired upon actuation of an initiator, a centrally apertured propellant body in said tube forwardly adjacent said igniter, a centrally apertured support member having an internally threaded forwardly opening hub portion and a peripheral O-ring seal in engagement with a mid-length portion of said tube, a charcoal bed intermediate said propellant body and support member, a longitudinally extending hollow gas rod secured in said support member hub portion and having a plurality of longituidinally spaced groups of peripherally spaced lateral openings, an annular baffle member between a pair of each of said openings and extending laterally outward from said rod toward said tube and defining a plurality of annular compartments, each of said compartments on the rearward side of each baffle being substantially filled with a coolant of ammonium carbonate, the forwardmost compartment being substantially filled with a gas filtering anhydros body for absorption of water, a plug secured in the forward end of said gas rod, an end cap secured to the forward end of said tube and defining a wall of said forwardmost compartment, said end cap having a forwardly opening internally threaded hub portion and a central passage in fluid communication with the interior of said end cap hub portion, a filter unit secured in said end cap central passage and located adjacent said anhydros body and forward of said plug, a deflector tube having inwardly extending rearmost flange means, means securing said tube flange means against said end cap, and a deflector secured in said end cap hub portion and located within and spaced from said deflector tube, said deflector having a hollow tubular portion terminating in a forwardmost closed end wall, said tubular portion having a plurality of lateral passages for directing cooled propellant gas toward the internal surface of said deflector tube.

Claim 4
Dependent Claim
19 words
The structure of claim 2 wherein an annular spacer is located intermediate said support member and said charcoal bed.
Claim 5
Dependent Claim
28 words
