Abstract
Abstract The invention relates to an apparatus for controlling the discharge of leakage fluids from the jet engines of an aircraft. The apparatus includes a storage tank for receiving the leakage fluids from the engine. Adjacent the discharge orifice of the storage tank is a control valve actuated by a switch responsive to the flow of air about the fuselage. Means are included for pumping the leakage fluids from the tank in response to an open condition of the valve. The fluids removed from the tank are directed into the exhaust jet of the engines for combustion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
91 words
An apparatus for controlling the leakage of fluids from the jet engines of an aircraft comprising a storage tank for receiving said leakage fluids from the engines of the aircraft, said storage tank defining an outlet orifice, an aerodynamically operated control means connected to said tank adjacent said outlet orifice serving to control the flow of fluids therefrom and a discharge pipe connected to said control means for directing said fluids from said tank to the exhaust jet of the engines as determined by the operational condition of said control means.
Claim 2
Independent Claim
91 words
An apparatus for controlling the leakage of fluids from the jet engines of an aircraft comprising a storage tank for receiving said leakage fluids from the engines of the aircraft, said storage tank defining an outlet orifice, an aerodynamically operated control means connected to said tank adjacent said outlet orifice serving to control the flow of fluids therefrom and a discharge pipe connected to said control means for directing said fluids from said tank to the exhaust jet of the engines as determined by the operational condition of said control means.
Claim 3
Dependent Claim
56 words
The apparatus of claim 1 wherein said control means includes a shutoff valve and an adjustable airflow sensing means positioned to sense the air velocity about the fuselage of the aircraft so as to actuate said shutoff valve from a closed to an open position when the air velocity about said fuselage reaches a predetermined value.
Claim 4
Dependent Claim
49 words
The apparatus of claim 2 which further comprises a jet pump pitot and a tube connected between said control valve and the exhaust end of said pipe and which serves to promote the removal of leakage fluids from said tank in response to the open condition of said valve.
Claim 5
Dependent Claim
21 words
The apparatus oF claim 3 which further comprises a directional flow control means located at the discharge end of said pipe.
Claim 6
Dependent Claim
33 words
The apparatus of claim 4 which further comprises a directional flow control means for controlling the direction of fluid flow between the engines and said tank so as to prevent reverse flow therethrough.
Claim 7
Dependent Claim
46 words
The apparatus of claim 1 wherein said control means includes a fluid pump and an adjustable air flow sensing means positioned for exposure to the air flow about the fuselage of the aircraft, said sensing means actuating said pump when a predetermined air velocity is attained.
Claim 8
Dependent Claim
21 words
The apparatus of claim 6 which further comprises a directional flow control means located at the discharge end of said pipe.
Claim 9
Dependent Claim
33 words
The apparatus of claim 7 which further comprises a directional flow control means for controlling the direction of fluid flow between the engines and said tank so as to prevent reverse flow therethrough.
Claim 10
Dependent Claim
43 words
The apparatus of claim 1 which further includes a level sensing means for sensing the fluid level within said tank so as to prevent actuation of said control means in the event the fluid level within the tank falls below a predetermined level.
Claim 11
Dependent Claim
70 words
The apparatus of claim 1 wherein said tank defines a plurality of outlet orifices, a plurality of said control means each of which is connected to said tank adjacent one of said orifices, a plurality of discharge pipes each of which is connected to one of said control means and aerodynamically sensitive means for simultaneously operating each of said control means in response to the air speed of the aircraft.
