  • Patent number: 4305705
    Abstract: Apparatus for igniting a main gas mixture to be burnt in a combustion chamber includes conduit systems for separately feeding an oxygen-bearing gas and a combustible gas into an ignition region. At least a part of at least one of the conduit systems is formed as an electrical heating resistance thereby to raise the temperature of the gas component flowing therein so that when the components are mixed in the ignition region, ignition of the ignition gas mixture will occur, thereby igniting the main gas mixture. The apparatus also includes means for detecting the temperature of the heated gas component or components flowing through the conduit systems, and/or the temperature of the gas mixture ignited in the ignition region.

  • Patent number: 4163464
    Abstract: The present specification describes and claims an arrangement for filling a vessel which is to be put under high pressure, with freely flowing solids from a storage vessel which is under normal pressure. The arrangement comprises a supply line extending between the storage vessel and the pressure vessel with a pressure sealing valve which can be tightly closed to counter the working pressure in the pressure vessel, and a shut-off valve suitable for sealing the storage vessel, arranged one behind the other in the supply line. The part of the supply line within the pressure vessel has at least one aperture in its wall and extends within a tube which also has an aperture or apertures, the tube and the supply line being so arranged that relative rotational movement there between opens and closes the aperture in the supply line. Thus, when the pressure vessel is full, the solids block off the supply line which is also full.
