  • Publication number: 20240117327
    Abstract: An enzymatically catalyzed method for producing L-glufosinate or a phosphoester of L-glufosinate can be performed. An activated L-homoserine HA is reacted with a substrate S selected from methylphosphinic acid and the esters of methylphosphinic acid. The method makes accessible new substrates in the enzymatic production of L-glufosinate and its phosphoesters.

  • Patent number: 11585542
    Abstract: The invention relates to a method for maintaining the temperature of fluid media in pipes even in the event of an interruption of the fluid media flow. In a first step, a heat reservoir layer (1) is produced comprising a latent heat reservoir material (2) and a matrix material (3). In a second step, the heat reservoir layer (1) is either arranged around a pipe (4) and subsequently encased with a heat damping material (5) or the heat reservoir layer (1) is brought into contact with heat damping material (5), whereby a heat reservoir damper composite (51) is obtained, and the pipe (4) is then encased with the heat reservoir damper composite (51) such that the heat reservoir layer (1) of the heat reservoir damper composite (51) lies between the pipe (4) and the heat damping material (5) of the heat reservoir damping composite (51).

  • Patent number: 11407076
    Abstract: A regeneration device for regenerating a coolant dispersion with phase change material includes: a redispersion unit for redispersing the coolant dispersion, the redispersion unit including a restrictor; and a recooling unit that enables freezing of a phase change material by dissipating heat stored in the coolant dispersion. The recooling unit is arranged so that dissipated heat is at least partially recuperated in order to heat up the coolant dispersion to an inlet temperature.

  • Patent number: 7700162
    Abstract: A method for applying a thin coating to a flat side (front side) and edge surfaces of a two-dimensional formation of graphite foil, includes applying the coating material to the flat side (front side) to be coated by electrostatic powder spraying followed by a sintering cycle or melting cycle. During the spraying, the two-dimensional formation is electrically contacted on a limited area virtually in the middle of its rear side, facing away from the spraying direction, on a limited area at a distance of at least 5 mm from the edges. A method for heat dissipation in electronic equipment, is also provided.

  • Publication number: 20080149322
    Abstract: Graphite films are provided with a metal coating of at most 100 nm thick and are produced, for example by a continuous vapor deposition process on graphite film. In spite of the small thickness of the metal layer, the graphite films can be connected to one another or to other components of metal or metal-coated materials by soldering. Furthermore, the thin metal coating protects the surface of the graphite film against particles breaking out or peeling or flaking off.

  • Patent number: 6910882
    Abstract: The invention comprises, in one form thereof, a continuous processing apparatus for high temperature thermal treatment of granular materials. The apparatus includes a vertical conveyor means with an internal feed mechanism for transporting granular feedstock upward, an external export means for taking reacted product downward wherein said internal feed heats said granular feedstock by absorbing heat from the product flowing downward through said export means, and a heating means disposed around a top portion of said vertical conveyor means and said external export means.
