  • Patent number: 11980930
    Abstract: A support unit for a roll shaft of a continuous casting guide roll includes a housing having first axial end face, a second axial end face and a through-opening extending from the first axial end face to the second axial end face, a first cover connected to the first axial end face, a first primary isolator arranged radially between the first cover and the roll shaft, and a bearing in the through opening. On a first side of the bearing, a first closed space is partially defined by the bearing, the first cover and the first primary isolator, and the first closed space is pre-filled with a lubricant.

  • Publication number: 20240139018
    Abstract: Provided is a finger tendon sheath brace capable of adjusting fixing pressure, including a brace fixing plate, a compression screw, a compression plate, an adjustable pressure push rod and a spring. The brace fixing plate is configured as a fixing structure for accommodating a finger to extend in the finger tendon sheath brace, and is provided with a threaded opening in a center of the brace fixing plate in a vertical direction perpendicular to the finger. The compression screw is embedded in the threaded opening of the brace fixing plate through threads to make an end of the compression screw slightly higher than the brace fixing plate and a head end of the compression screw pass through the brace fixing plate and enter a cavity for accommodating the finger. The compression plate is connected with a head end of an adjustable pressure push rod inner sleeve.

  • Patent number: 11971513
    Abstract: Methods of and systems for forming an image of a subterranean region of interest are disclosed. The method includes obtaining an observed seismic dataset and a seismic velocity model for the subterranean region of interest and generating a simulated seismic dataset based on the seismic velocity model and the source and receiver geometry of the observed seismic dataset. The method also includes forming a plurality of time-windowed trace pairs from the simulated and the observed seismic datasets, and forming an objective function based on a penalty function and a cross-correlation between the members of each pair. The method further includes determining a seismic velocity increment based on the extremum of the objective function and forming an updated seismic velocity model by combining the seismic velocity increment and the seismic velocity model, and forming the image of the subterranean region of interest based on the updated seismic velocity model.

  • Publication number: 20240125955
    Abstract: A method for forming an image of a subterranean region of interest, using an observed seismic dataset, a seismic velocity model and a simulated seismic dataset based in part, on the seismic velocity model is provided. This method includes forming trace pairs from the simulated and observed seismic dataset, wherein each of the trace pairs comprises of an observed trace and a simulated trace. An objective function is formed based on a penalty function and a phase cross-correlation between the observed and simulated seismic trace of each of the trace pairs. This method further includes determining an extremum of the objective function and a seismic velocity increment based on the extremum. The seismic velocity model is updated by combining the seismic velocity increment and the seismic velocity model and the image of the subterranean region of interest is formed based in part, on the seismic velocity model.

  • Publication number: 20240081418
    Abstract: A liquid injection device includes: an accommodating cavity for detachable mounting of an electronic vaporization device; a liquid storage tank; a liquid supply mechanism; and a control assembly. The control assembly is connected to the liquid supply mechanism and detects whether the electronic vaporization device is mounted in the accommodating cavity. The liquid supply mechanism is in communication with the liquid storage tank to: be connected to the electronic vaporization device and supply liquid to the electronic vaporization device when the electronic vaporization device is mounted in the accommodating cavity, and be disconnected from the electronic vaporization device and stop supplying liquid to the electronic vaporization device when the electronic vaporization device is removed from the accommodating cavity.
