Patent number: 12122985Abstract: The invention discloses cleaning compositions which employ a synergistic combination of an ester solvent, preferably a fatty acid methyl ester in combination with one or more linear alkyl amines. The alkyl amines act as to remove and suspend organic oils which have been burnt or adhered to a surface with heat and may even be used alone as a soil removal agent. The cleaning compositions have particular use in cleaning of distillation towers associated with biofuel, and vegetable oil refining, but also find use in cleaning ovens, food cooking surfaces and even dry cleaning.Type: GrantFiled: December 28, 2021Date of Patent: October 22, 2024Assignee: ECOLAB USA INC.Inventors: Chris Nagel, Eric Victor Schmidt, Mark Levitt, Peter J.

Patent number: 10886437Abstract: An inorganic coating may be applied to bond optically scattering particles or components. Optically scattering particles bonded via the inorganic coating may form a three dimensional film which can receive a light emission, convert, and emit the light emission with one or more changed properties. The inorganic coating may be deposited using a low-pressure deposition technique such as an atomic layer deposition (ALD) technique. Two or more components, such as an LED and a ceramic phosphor layer may be bonded together by depositing an inorganic coating using the ALD technique.Type: GrantFiled: November 2, 2017Date of Patent: January 5, 2021Assignee: Lumileds LLCInventors: Michael Camras, Jyoti Bhardwaj, Peter J.

Patent number: 10290775Abstract: A semiconductor light emitting device comprising a light emitting layer disposed between an n-type region and a p-type region is combined with a ceramic layer which is disposed in a path of light emitted by the light emitting layer. The ceramic layer is composed of or includes a wavelength converting material such as a phosphor. Luminescent ceramic layers according to embodiments of the invention may be more robust and less sensitive to temperature than prior art phosphor layers. In addition, luminescent ceramics may exhibit less scattering and may therefore increase the conversion efficiency over prior art phosphor layers.Type: GrantFiled: July 11, 2017Date of Patent: May 14, 2019Assignee: Lumileds LLCInventors: Gerd O. Mueller, Regina B. Mueller-Mach, Michael R. Krames, Peter J. Schmidt, Hans-Helmut Bechtel, Joerg Meyer, Jan de Graaf, Theo Arnold Kop
