Abstract: A collapsible fire fighting bucket assembly to be suspended from an aircraft for fighting wild fires, the bucket being made of pliable material and having an open upper end for filling from a body of water. A tubular extension extends from an opening in the bottom of the bucket and has a free end formed with a discharge port provided with resilient sealing lips which are brought into sealing engagement with each other to close the port to minimize water leakage from the tubular extension. A harness suspends the bucket from the aircraft and a releasable support releasably supports the free end of the tubular extension within the bucket body extending upwardly from the opening to close the discharge port. The releasable support cooperates with the openings to allow the tubular extension to be rapidly lowered so as to extend downwardly from the bottom to open the discharge port for dumping the water. The sealing lips are drawn together by purse lines passing through openings adjacent the discharge port but spaced from the sealing lips to avoid abrasion of the lips that occurred with prior art bucket valves. The purse lines cooperate with the releasable support to control location of the free end of the tubular extension.

Title: Polystyrene foam and process for making the same
Inventor: DALKE BRIAN D
IPC: C08J9/12
Filed: 1993-04-12
Abstract: An improved polystyrene foam having less corrugation is disclosed which uses carbon dioxide as the blowing agent and 1-30 weight percent endothermic agent, such as water, with the weight based on the total carbon dioxide blowing agent and endothermic agent weight. This combination of carbon dioxide and endothermic agent decreases the corrugation of the thermoplastic foam, while just slightly increasing density, when the process parameters, including throughput, are equivalent to using only carbon dioxide. The process also allows an increased foaming temperature and greater process throughput of an equivalent density thermoplastic foam at approximately equivalent corrugation levels when compared to the use of only using carbon dioxide.
