20100101401 | APPARATUS AND METHOD FOR DISPENSING INCENDIARY PROJECTILES - An apparatus and method for dispensing incendiary projectiles is provided. The apparatus includes an injector for injecting the projectiles with a reactant at a dispensing rate, and a controller operable to control the dispensing rate. The controller is operable to control solenoids of a dispenser gate and a shuttle motor, and to prevent jam conditions of the apparatus. The apparatus can detect and automatically correct jam conditions that do occur. The apparatus can count the number of incendiary projectiles dispensed during a current operation and during the lifetime of the apparatus. The apparatus is dimensioned to minimize the number of incendiary projectiles purged from the apparatus after an operator has indicated to stop dispensing. | 04-29-2010 |
20110232926 | FIRE FIGHTING BUCKET FOR AIRCRAFT - A collapsible fire fighting bucket for being suspended from a helicopter having an open bucket body of pliable material with an open rim and an opening in the bottom, an annular base member of pliable material that is attached to the bottom adjacent to the opening, a tubular extension (i.e. dump valve) made of pliable material and having a base portion at one end and a free end at the other end with a discharge port, and a heavy duty watertight zipper releasably connecting the base portion of the tubular extension to the annular base member on the bucket body. The zipper enables the dump valve to be easily removed from, and reattached to, the bucket thereby providing an efficient mechanism for replacing a worn out dump valves. | 09-29-2011 |
20120222874 | MULTI-DUMP METERING VALVE - Valves having an inner assembly comprising: a base plate spaced apart from a top plate to define therebetween an open side, the base plate defining an outlet; an outer assembly comprising solid side walls and being movable relative to the inner assembly between open and closed positions, an upper portion of the solid side walls seal with the top plate only when the outer assembly is in the closed position, a lower portion of the solid side walls seal with the base plate only when the outer assembly is in the closed position, wherein the open position allows flow through the valve via the open side portion and the outlet of the outer assembly; and an actuator mounted to the inner assembly and connected to the outer assembly to move the outer assembly between the open and closed positions in response to electrical control signals. | 09-06-2012 |
