  • Patent number: 10969340
    Abstract: A heating chamber (1) for a heating furnace is proposed, with which electrothermal vaporization of impurities from samples can be effected in order to be able to then analyze them spectrometrically. The heating chamber has a wall (3), a sample reception area (5), a nozzle area (7) and two electrical connection areas (9, 11). The heating chamber (1) is specially configured such that an electric current flows through the wall (3) in such a way that a heating capacity caused by it is higher in the nozzle area (7) than in the sample reception area (5).

  • Patent number: 10299747
    Abstract: The disclosure provides a device having a C-arm, the C-arm including a main body of which the cross-sectional profile is formed as a double H, an outer wall, an inner wall and two side walls of the main body forming a rectangular cavity. The device also includes running wires arranged on the main body and running rollers, on which the C-arm is movably mounted, rolling on the running wires. The running wires and the running rollers are arranged in such a way that at least 50 percent of the mounting forces acting on the running wires due to the running rollers is introduced into the side walls of the main body. The disclosure also provides an x-ray imager having such a device. The disclosure offers the advantage that undesired oscillations of the C-arm are avoided.

  • Publication number: 20160319410
    Abstract: The invention relates to a method for producing a composite component and to a composite component, the composite component being formed from a metal-matrix composite material made of carbon fibers and a metal or a metal alloy, a fiber composite being formed from the carbon fibers, a preform being formed from the fiber composite, the carbon fibers of the fiber composite being coated with pyrolytic carbon to form the preform, the preform being at least partially infiltrated with molten metal.
