Filed:

Nov 21, 1984

Appl. No.:

6/673708

Inventors:

Paul F. Halfpenny - Van Nuys CA

Assignee:

Lockheed Corporation - Calabasas CA

International Classification:

A62C 1100

US Classification:

169 30

Abstract:

The invention is a device for coupling an outlet port of a fire extinguisher containing a source of pressurized fire suppression chemical to the interior of a closed-off compartment 12 having a pierceable wall 14. The device comprises a cylinder 22 having a moveable ram portion 66 adapted to pierce the wall 14 upon the cylinder receiving the pressurized fire suppression chemical. The cylinder 22 includes first and second ends 26, 32, the first end closed off by a first wall 28, the cylinder 22 further having an inlet port 30 in proximity to the first end 26. A piston 50 is moveably mounted within the cylinder 22, forming a closed-off chamber 56 within the cylinder. The piston 50 includes a piston rod 64 coupled to the ram portion. The piston 50 further includes passages 68, 70 coupling the chamber 56 to the exterior surface of the ram portion 66. A sealing disk 92 having a plurality of support rods 94 are moveably mounted through a plurality of holes 90 in the piston 50, with the length of the rods being greater than the thickness of the piston.

Abstract:

An improved humidification system for jet-powered commercial aircraft comprising an evaporator adapted to add moisture to a gas flow, a gas flow control system for applying to the evaporator a gas flow having an internal energy sufficient to vaporize the moisture and a temperature measuring system for measuring the temperature of the gas flow exiting from the evaporator for regulating the amount of moisture added to the gas flow so as to maintain the evaporator exit temperature constant is disclosed. In a particular embodiment, the humidification system consists of a tank having an outlet duct adapted to deliver moisturized air to the passenger compartment of the aircraft, a water injection system adapted to flow water into the tank upon the temperature within the outlet duct rising above a preselected value and to terminate water flow upon the temperature falling below the preselected value, and a gas flow control system coupled to the tank and adapted to control the flow of air into the tank at a rate such that the air has sufficient internal energy to vaporize the water. An evaporator plate system is incorporated within the tank to ensure that all the injected water is vaporized before exiting the tank. Additionally, a demisting filter is mounted between the evaporator plate system and the outlet duct to ensure that all particulate matter is removed from the moisturized air before leaving the tank.

International Classification:

A61M 1500

US Classification:

12820113

Abstract:

The invention is a humidification face mask 10 comprising a closed container 12 having side walls 20 and first and second end walls 14 and 16. The first wall 14 incorporates an aperture 30 therethrough. A flexible, tubular-shaped member 60 is provided, having first and second ends 61 and 62. The first end 61 is coupled to the second end wall 16 and the opposite end 62 is adapted to fit over the mouth and nose. An inlet valve 36 is provided which is adapted to allow humidified air from the interior of the container 12 to the interior of the member 60. A vent valve 33, biased to the closed position, is provided which is adapted to allow exhausted air in the member 60 to pass into the interior of the container 12. A passage assembly 40 coupling the vent valve 33 to the interior of the container 12 is also provided. An open-celled foam member 42 is mounted within the container 12 between the aperture 30 and the inlet valve 36 adapted to receive and hold water.
