TL;DR: In this article, an auxiliary pilot valve is used in a household gas heater control, which is maintained on when the control is turned toward an irreversible safety lock position, and a reduced pilot light is produced by the auxiliary flow.
Abstract: The invention includes an auxiliary pilot valve for use in a household gas heater control. The auxiliary pilot valve flow is maintained on when the control is turned toward an irreversible safety lock position. A reduced pilot light is produced by the auxiliary flow. The reduced pilot light is small and fails to heat a thermocouple to a high temperature. A safety magnet valve connected from the thermocouple then closes off all gas entry to the control after thermocouple cools.

TL;DR: In this paper, the external surface of the front and back electromode of the ARC GAS HEAT is described. And the magnetic field is used to prevent the ARC foot from being stuck between the front-and back-electromode.
Abstract: EXTERNAL SURFACE OF THE FRONT ELECTRODE OF THE ARC GAS HEATER. METAL OXIDES, SUCH AS TITANIUM DIOXIDE, ARE PREPARED BY VAPOR PHASE OXIDATION OF CORRESPONDING METAL HALIDES IN A REACTION SPACE SUPPLIED WITH HEAT ENERGY FROM A GAS STREAM HEATED BY ELECTRICAL ENERGY. ARC GAS HEATERS HAVING FROM AND BACK ELECTORDES ARE DESCRIBED. MAGNETIC FIELD MEANS ABOUT THE FRONT ELECTRODE ARE USED FOR PREVENTING ELONGATION OF THE ARC STRUCK BETWEEN THE FRONT AND BACK ELECTRODE AND PREVENTING LOCATION OF THE ARC FOOT ON THE

TL;DR: In this paper, the present stage of development of combustion chambers for fossil-fired closed-cycle gas turbines is discussed, describing West Germany's "Gelsenkirchen" plant which can be operated with blast-furnace gas and fuel oil with any desired ratio of gas to oil.
Abstract: The paper discusses the present stage of development of combustion chambers for fossil-fired closed-cycle gas turbines, describing West Germany’s “Gelsenkirchen” plant which can be operated with blast-furnace gas and fuel oil with any desired ratio of gas to oil. The output data and the efficiency of this plant are illustrated by test results. In the development and construction of fossil-fired closed-cycle gas turbine plants, the gas heater presents the greatest difficulties and is the most expensive part of the plant. Therefore, very detailed measurements were taken to determine the total heat absorption in the combustion chamber and its local distribution over the length of the chamber. The results obtained are compared with previous measurements at a smaller plant, the mine-gas and pulverized-coal fired “Haus Aden” plant.Copyright © 1970 by ASME

TL;DR: In this paper, experiments on heat transfer in the motion of a high-enthalpy gas through a tube are presented in the form of a general relationship St = f(Re, H/H0,l/d).
Abstract: Results are given from experiments on heat transfer in the motion of a high-enthalpy gas through a tube; the results are presented in the form of a general relationship St=f(Re, H /H0,l/d).
