Title: Fuel regulator for gas turbines - has environmental temperature dependant fuel rate flow correcture valve to move fuel line throttle
IPC: F02C9/38
Filed: 1975-12-10
Abstract: Fuel is fed to the jects from a pump via a pipe system. The flow rate is determined by a regulator cross bore and fuel opening sizes of the fuel correcture slide valve as well as the pressure drop on the regulator and slide valves. The fuel pressure drop is held constant by the correcture valve. A temp. sensor responds to changes in the atmosphere air by displacing by a bellow, a sprung slide valve which correspondingly increases or decreases the slide valve opening cross sections to adjust the fuel flow rate to the jets.

Title: Open:ended tubular high temperature furnace - with inert gas curtain protecting carbon heater element
Inventor: GOURONNEC ALAIN
IPC: H05B6/02
Filed: 1976-02-06
Abstract: Furnace for use at very high temps. esp. above 2300 degrees C has a furnace chamber in contact with the external atmos. The chamber consists of a tubular heating element provided with inlets for neutral gas at both ends so lateral gas flow prevents the oxidn. of the element, but the latter is accessible during operation, the element is located in an outer casing filled with neutral gas. The tubular element pref. has an inner lining of vitreous carbon and an outer sheath of silica, alternatively a graphite element may be used. A pump pref. draws the gas out of the casing so prods. produced by sublimation of the element do not reach the workpiece. The neutral gas is pref. Ar, N2, He, or their mixts. and heating is pref. by induction or by resistance. Used e.g. for the drawing of optical fibres. Accessibility to the furnace chamber during operation is very good, a very steep temp. gradient is obtd. and rapid heating is possible, e.g. in less than 5 mins.
