  • Patent number: 6644959
    Abstract: The invention relates to an atomizer burner for a motor vehicle heater, with a cobustion chamber which contains a baffle barrier and with an atomizer means (2) which atomizes the fuel into the combustion chamber, characterized in that within the combustion chamber in the atomization direction of the fuel at a distance from the atomization point of the atomizer means (2) which is smaller than the diameter of the combustion chamber or the diameter of a cylindrical heat shield (8) which extends in the combustion chamber there is a baffle plate (18) which acts as a baffle barrier.

  • Publication number: 20020008098
    Abstract: A process for the heat treatment of semiconductor wafers, preferably monocrystalline ultrapure silicon wafers, using an upper and a lower heat source, which can be a plurality of upper and a plurality of lower lamps or banks of lamps. In the process chamber of an RTP system, the heat treatment is carried out on at least two wafers which are arranged parallel above one another, spaced apart, and are identical in terms of geometrical dimensions and thermal material properties.

  • Patent number: 5020991
    Abstract: A heating device, especially a motor vehicle heating device operated by means of liquid fuel, has a vaporization burner with an absorbent body that can be acted upon by liquid fuel. To effect equalization of heat distribution and fuel pretreatment, there is provided a cover of a high temperature and corrosion resistant sheet steel. The cover has a plurality of openings and covers at least a major portion of that surface of the absorbent body which faces a combustion chamber of the heating device. When the absorbent body has a through-opening to promote vaporization of the liquid fuel, the cover likewise can have a through-opening coordinated thereto, thus exposing the through-opening.

  • Patent number: 4923033
    Abstract: A heating device, particularly an automotive heating device, in which a noise muffling device is integrated within the heating device. The muffler can be provided in the combustion pipe defining the combustion chamber, or the combustion pipe, itself, can be designed as the muffler. The muffler operates by absorption and/or reflection sound muffling techniques in accordance with various embodiments, and may, simultaneously, purify the combustion gases, for example, by catalytic afterburning, and/or by filtering of soot particles. The muffler is arranged in a hot zone, but not in the flame area of the combustion chamber, to achieve a self-cleaning action. In other embodiments, noise muffling material is arranged in an exhaust gas collection chamber to achieve sound muffling based on reflection and/or absorption and/or other conventional sound reduction methods. In all cases, the need for an external muffler in the exhaust line from the heating device is eliminated.
