| 20110168415 | DISPENSING VALVE AND METHOD FOR DISPENSING A FLUID UNDER PRESSURE - A dispensing valve apparatus and method for rapidly dispensing fluid from a fluid reservoir of a pressure vessel include a piston translatable within a cavity that closes a discharge passage opening the cavity when positioned in a first position and opens the discharge passage to fluid flow from the fluid reservoir when positioned in a second position. The piston may be rapidly repositioned from its position to its second position by venting a cavity disposed between the piston and an actuator cap by selectively opening a check valve to vent the pressure within the cavity to the discharge passage. | 07-14-2011 |
| 20110151387 | IGNITION CONTROL WITH SAFEGUARD FUNCTION - An ignition control and method are provided for overseeing an ignition process on a fuel-fired appliance having a fuel burner, a fuel flow control valve, an ignition source, and a flame detection device. A primary processor initiates the ignition process, monitors the flame status signal and terminates the ignition process in the presence of a flame status signal indicating no flame after a specified period of time following the initiation of the ignition process. A secondary processor monitors the flame status signal independently of the primary processor and terminates the ignition process in the event that the primary processor fails to terminate the ignition process in the presence of a flame status signal indicating no flame after a specified period of time following the initiation of the ignition process. The primary and secondary processors may each have the functional capability to monitor the operation of the other. | 06-23-2011 |
| 20110073795 | FIRE EXTINGUISHING COMPOSITION - A fire extinguishing composition is provided that is suitable for use as a fire extinguishing agent in fire suppression, particularly in off-road vehicles exposed to low ambient temperature environments. The fire extinguishing composition includes an aqueous solution of potassium formate. In an embodiment, the fire extinguishing composition includes an aqueous solution of potassium formate and an aqueous film forming foam. In an embodiment, the fire extinguishing composition is an aqueous solution including an aqueous film forming foam, potassium formate and potassium acetate in water. | 03-31-2011 |
