  • Patent number: 11131030
    Abstract: Various embodiments include an electrolysis cell with a housing with an anode and a gas diffusion electrode connected as cathode. The gas diffusion electrode has an electrolyte side and a gas side and separates the electrolyte space from a gas space for a reaction gas. There is a support body disposed in the gas space with a contact surface in contact with the gas diffusion electrode. The gas space comprises a first channel system and a second channel system. The first channel system and the second channel system run separately from one another and thus form two separate volumes of the gas space. The first channel system and the second channel system each have openings in the contact surface of the support body.

  • Publication number: 20190233958
    Abstract: Various embodiments include a system for carbon dioxide electrolysis comprising: an electrolysis cell having an anode and a cathode comprising a gas diffusion electrode adjoined by a gas space and a cathode space; an electrolyte circuit adjoining the electrolysis cell; a gas supply for supplying carbon dioxide-containing gas to the gas space, the gas space including an electrolyte outlet; and a shutoff device for the electrolyte outlet, wherein the shutoff device opens when a pressure differential between the gas space and the cathode space exceeds a threshold value.

  • Publication number: 20180037841
    Abstract: Provided are lubricating engine oils including a lubricating oil base stock as a major component having a base oil viscosity at 100 deg. C. ranging from 4.5 to 7.5 cSt, and a carboxylic functionalized polymer dispersant with aromatic amine functionality, as a minor component, wherein the lubricating engine oils have a cold crank simulator viscosity at ?30 deg. C. of less than 8500 mPa·s. The lubricating engine oils may provide improved engine wear protection at equivalent fuel efficiency or improved fuel efficiency at equivalent engine wear protection compared to a lubricating engine oil containing a dispersant as a minor component other than the carboxylic functionalized polymer with aromatic amine functionality. Methods of making the lubricating engine oil are also provided. The lubricating engine oils are useful in internal combustion engines including direct injection, gasoline and diesel engines.

  • Patent number: 7575350
    Abstract: An infrared lighting device for motor vehicles, for example a headlight, has a radiation source and a filter, whereby the device emits white and infrared radiation at a certain intensity in a wavelength range between 800 and 1200 nm on one axis, and the filter at a first angle may transmit a first visible part and at a second angle different from the first may transmit a second visible part of the radiation source, and both parts transmitted form white light.

  • Patent number: 5977711
    Abstract: The present invention relates to a method and system for optimizing the output of at least two electron guns in a cathode ray tube for aging the cathode ray tube during manufacture. The system comprises at least two electron guns located in the cathode ray tube and a memory configured to store an offset value that is representative of a difference between a maximum output level and a detected output level for each of the electron guns. The system further comprises a processor coupled to the memory. The processor generates a first scaled signal by adding a first signal representative of an input voltage corresponding to the detected output level of the first electron gun and an offset signal representative of the offset value, and a second scaled signal by adding a second signal representative of an input voltage corresponding to the detected output level of the second electron gun and the offset signal.
