    摘要: This burner comprises a gas distributor (20) with a row of gas injectors (5a to 5e), the tube being axially inside an air distributor tube. Each gas injector extends through the wall of the air distributor tube via a coaxial air outlet aperture. The gas distributor tube includes two sealing bodies (36, 37) sliding symmetrically on either side of a central gas inlet aperture (21). Each of these bodies is provided with an eccentric longitudinal threaded bore (38, 39) engaging a threaded section of a rotating control rod (41). The two sections (48, 49) are threaded in opposite directions to the thread of the sealing bodies (36, 37), which enables them to move these two sealing bodies simultaneously in order to gradually interrupt or restore the supply of gas to the injectors (5a to 5e) situated at the end of the row without interrupting the supply to the air injectors.

    摘要: The invention concerns a thermal transfer layer with high transfer coefficient between two materials which can have different expansion coefficients. The thermal transfer layer comprises expanded graphite inserted between the materials which are selected from among carbonaceous materials, ceramics and metals or metal alloys. The expanded graphite is either inserted in the form of a rolled or compressed sheet, or is compressed in situ. The invention also concerns a device for the cooling of a structure subjected to intense, continuous, intermittent or pulsating heat flux, by means of fluid circulation tubes placed in the passages in the structure. A flexible material which is a good heat conductor in a compressed state, such as expanded graphite, is placed between the structure to be cooled and each tube.

    摘要: The invention concerns a process for the production of vapor-deposited carbon fibres wherein a gaseous or vaporized hydrocarbon which is entrained by a carrier gas is pyrolyzed on a substrate in a flow reactor at a temperature of between 950.degree. and 1300.degree. C. in two successive stages, a germination stage and a growth stage.The process comprises the following steps:preparing a gaseous mixture comprising from 50 to 90% and preferably from 85 to 65% by volume of hydrogen and/or helium and from 10 to 40% and preferably from 15 to 35% by volume of methane;circulating the mixture in the reactor over a substrate comprising from 10.sup.-8 to 10.sup.-4 g/cm.sup.2 of a catalyst selected from iron, nickel, cobalt and alloys thereof;initiating germination and growth of the carbon fibres in respect of length at a temperature t1 which is stabilized at between 950.degree. and 1050.degree. C., with a substantially constant velocity of the gaseous mixture of between 10 and 50 centimeters per minute for a period of between 10 and 90 minutes;causing growth of the carbon fibres in respect of diameter at a temperature t2 which is higher than 1050.degree. C. and which can attain approximately 1300.degree. C., with a progressively increasing velocity of the gaseous mixture; andcooling the reactor under an inert gas before extracting the carbon fibres.
