Emergency oxygen release system and coupling

Claim 1

A SYSTEM FOR SUPPLYING A PRESSURIZED MEDICINAL GAS AT LEAST TWO DIFFERENT RATES OF FLOW, TO THE PERSONNEL OF AN AIRCRAFT, COMPRISING: GAS SOURCE-MEANS INCLUDING MEANS FOR NORMAL SUPPLY OF SAID GAS AT A LOW PRESSURE; GAS-FLOW REGULATOR MEANS CONNECTED TO SAID MEANS FOR SUPPLY OF GAS AT SAID LOW PRESSURE; SAID GAS SOURCE-MEANS INCLUDING MEANS RESPONSIVE TO A REDUCTION IN THE PRESSURE OF THE AMBIENT AIRCRAFT AIR IN WHICH SAID SOURCE MEANS IS LOCATED FOR FORWARDING SAID GAS AT AN INCRESED PRESSURE; FLOW CONTROL MEANS HAVING AN OUTLET INTO THE AIRCRAFT AND LOCATED OUTWARDLY IN THE SYSTEM AND ARRANGED AND CONNECTED TO RECEIVE BOTH THE LOW PRESSURE GAS AND THE HIGHER PRESSURE GAS AND EFFECTIVE TO EMIT EITHER, LOW OR HIGH, PRESSURE GAS AND FLOW CONTROL MEANS INCLUDING FIRST, NORMALLY CLOSED VALVE MEANS NORMALLY CONNECTED TO SAID MEANS FOR SUPPLYING LOW PRESSURE GAS AND TO SAID OUTLET, MANUAL MEANS ARRANGED TO OPEN SAID NORMALLY CLOSED VALVE SO AS TO PASS SAID LOW PRESSURE GAS OUT OF SAID OUTLET; AUTOMATIC MEANS RESPONSIVE TO THE DIFFERENTIAL IN PRESSURE BETWEEN THAT PRESSURE WHICH IS NORMAL IN SAID AIRCRAFT AND THAT PRESSURE WHICH EXISTS UPON DECOMPRESSION OF SAID AIRCRAFT, SAID AUTOMATIC MEANS BEING AUTOMATICALLY COMMUNICATED UPON DECOMPRESSION WITH SAID MEANS FOR FORWARDING SAID GAS AT SAID INCREASED PRESSURE FROM SAID SOURCE MEANS, SAID MEANS RESPONSIVE TO SAID DIFFERENTIAL PRESSURE BEING EFFECTIVE UPON OCCURRENCE OF SAID RESPONSIVE TO OPEN A PATH THROUGH THE FLOW CONTROL MEANS TO CAUSE EMISSION FROM SAID OUTLET OF SAID GAS AT AN ELEVATED PRESSURE.

Claim 2

A SYSTEM FOR SUPPLYING A PRESSURIZED MEDICINAL GAS AT LEAST TWO DIFFERENT RATES OF FLOW, TO THE PERSONNEL OF AN AIRCRAFT, COMPRISING: GAS SOURCE-MEANS INCLUDING MEANS FOR NORMAL SUPPLY OF SAID GAS AT A LOW PRESSURE; GAS-FLOW REGULATOR MEANS CONNECTED TO SAID MEANS FOR SUPPLY OF GAS AT SAID LOW PRESSURE; SAID GAS SOURCE-MEANS INCLUDING MEANS RESPONSIVE TO A REDUCTION IN THE PRESSURE OF THE AMBIENT AIRCRAFT AIR IN WHICH SAID SOURCE MEANS IS LOCATED FOR FORWARDING SAID GAS AT AN INCRESED PRESSURE; FLOW CONTROL MEANS HAVING AN OUTLET INTO THE AIRCRAFT AND LOCATED OUTWARDLY IN THE SYSTEM AND ARRANGED AND CONNECTED TO RECEIVE BOTH THE LOW PRESSURE GAS AND THE HIGHER PRESSURE GAS AND EFFECTIVE TO EMIT EITHER, LOW OR HIGH, PRESSURE GAS AND FLOW CONTROL MEANS INCLUDING FIRST, NORMALLY CLOSED VALVE MEANS NORMALLY CONNECTED TO SAID MEANS FOR SUPPLYING LOW PRESSURE GAS AND TO SAID OUTLET, MANUAL MEANS ARRANGED TO OPEN SAID NORMALLY CLOSED VALVE SO AS TO PASS SAID LOW PRESSURE GAS OUT OF SAID OUTLET; AUTOMATIC MEANS RESPONSIVE TO THE DIFFERENTIAL IN PRESSURE BETWEEN THAT PRESSURE WHICH IS NORMAL IN SAID AIRCRAFT AND THAT PRESSURE WHICH EXISTS UPON DECOMPRESSION OF SAID AIRCRAFT, SAID AUTOMATIC MEANS BEING AUTOMATICALLY COMMUNICATED UPON DECOMPRESSION WITH SAID MEANS FOR FORWARDING SAID GAS AT SAID INCREASED PRESSURE FROM SAID SOURCE MEANS, SAID MEANS RESPONSIVE TO SAID DIFFERENTIAL PRESSURE BEING EFFECTIVE UPON OCCURRENCE OF SAID RESPONSIVE TO OPEN A PATH THROUGH THE FLOW CONTROL MEANS TO CAUSE EMISSION FROM SAID OUTLET OF SAID GAS AT AN ELEVATED PRESSURE.
