  • Patent number: 10597345
    Abstract: Provided herein are methods of inhibiting polymerization of vinyl aromatic monomers. The methods include distilling a vinyl aromatic monomer in a distillation column to form a vinyl aromatic monomer distillate; removing the vinyl aromatic monomer distillate from the distillation column; combining the vinyl aromatic monomer distillate with 4-tert-butylcatechol (TBC) to form a treated distillate; and adding a reflux liquid that includes the treated distillate to the distillation column liquid of the distillation column. An added oxygen gas may be present in a distillation column liquid in an amount of at least 1 ppmw, based on the weight of the vinyl aromatic monomer.

  • Patent number: 10578376
    Abstract: The present invention relates to a fin (103) for a plate heat exchanger having an angular, wave-shaped structure with wave crests (131) arranged in parallel to one another, wherein a wave crest (131) is connected via a wave flank (132) to another wave crest (131), and wherein the wave crest (131) and the wave flank (132) succeed one another in a first spatial direction (D1), and wherein the wave crest (131) and the wave flank (132) are connected to one another by a sheet edge (134). The wave crests (131) have a flat outer surface (135). According to the invention, the outer radius (R101) of the sheet edges (134) is 0.05 mm to 0.18 mm. A method for manufacturing a fin (103) is also provided, which comprises a pressure-shaping step in which a previously provided bent wave-shaped structure (3) is shaped such that the outer radius (R1) of the sheet edges (34) is reduced (R101).

  • Patent number: 10490385
    Abstract: An anode for an X-ray tube can include a body comprising one or more of a yttrium-oxide derivative, titanium diboride, boron carbide, titanium suboxide, reaction bonded silicon carbide, and reaction boded silicon nitride. Upon collision with an anode, the kinetic energy of an electron beam in an X-ray tube is converted to high frequency electromagnetic waves, i.e., X-rays. An anode with a body from one or more of the above materials can reduce costs and/or weight, extend the life of the anode or associated components (e.g., bearings) and simultaneously provide a high heat storage capacity than traditional molybdenum and tungsten anodes.
