Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
THE COMBINATION, WITH A REACTION MOTOR HAVING A SECONDARY COMBUSTION CHAMBER, A FLAME HOLDER UPSTREAM FROM SAID SECONDARY COMBUSTION CHAMBER, A MIXING CHAMBER UPSTREAM FROM SAID FLAME HOLDER, AND FUEL INJECTION MEANS DISPOSED IN SAID MIXING CHAMBER; OF A COMBINED FLAME DETECTOR AND THERMOCOUPLE POSITIONED IN SAID MIXING CHAMBER, SAID FLAME DETECTOR HAVING AN ELECTRICAL OUTPUT OF A CHARACTERISTIC VALUE WHEN A FLAME IS INCIDENT THEREON, MEANS CONTROLLED BY SAID FLAME DETECTOR TO DECREASE AUTOMATICALLY THE AMOUNT OF FUEL SUPPLIED TO SAID INJECTION MEANS WHEN THE FLAME DETECTOR OUTPUT ASSUMES SAID CHARACTERISTIC VALUE, TEMPERATURE INDICATING MEANS, FUEL CONTROL MEANS, AND MEANS OPERATIVELY CONNECTING SAID THERMOCOUPLE WITH SAID TEMPERATURE INDICATING AND FUEL CONTROL MEANS.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
116 words
A COMBINATION THERMOCOUPLE AND FLAME DETECTOR COMPRISING A GENERALLY CYLINDRICAL CONDUCTIVE SUPPORT, A SOLID GENERALLY HEMISPHERICAL MEMBER OF CERAMIC MATERIAL SECURED TO ONE END OF SAID SUPPORT, A THERMOCOUPLE JUNCTION IMBEDDED IN SAID CERAMIC MATERIAL, LEADS EXTENDING THROUGH SAID SUPPORT AND SAID MEMBER TO SAID THERMOCOUPLE JUNCTION, ONE OF SAID LEADS ELECTRICALLY CONTACTING SAID CERAMIC MATERIAL, THE POTENTIAL ACROSS SAID LEADS INDICATING THE TEMPERATURE AT THE THERMOCOUPLE JUNCTION, ANOTHER LEAD CONNECTED TO SAID CERAMIC MATERIAL AT A POINT SPACED FROM THE POINT OF CONTACT OF SAID ONE LEAD WITH SAID CERAMIC MATERIAL, WHEREBY WHEN A FLAME CONTACTS SAID CERAMIC TIP A CURRENT FLOWS BETWEEN SAID SPACED POINTS AND IN THE LEADS CONNECTED TO SAID SPACED POINTS.
