  • Patent number: 11931671
    Abstract: A three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields is provided, which is applied to quick degassing of a gas-liquid two-phase flow. The three-stage tubular T-shaped degassing device adopts a quick degassing technology combining a microbubble uniform mixed rotational axial flow field and a spiral runner conical spiral flow field with layered jet collision reversing depth degassing. A microbubble uniform mixer is configured to adjust gas-liquid two-phase flow containing big bubbles into microbubble uniform mixed axial flow. A microbubble cyclone is configured to adjust the microbubble uniform mixed axial flow into multiple strands of rotational axial flows containing microbubbles. A rotational axial flow degasser implements the horizontal type microbubble uniform mixed multiple strands rotational axial flow degassing operation to remove most microbubbles to form axial flow gas and axial flow liquid.

  • Patent number: 11706301
    Abstract: Methods and terminal devices, including computer programs encoded on computer storage media, for selecting a server node. According to one of the methods, a terminal device first sends a connection request to one server node, and then sends a connection request to another server node after a time interval T. The terminal device first sends a connection request to a first server node. If the terminal device receives, within a first preset duration T, response information fed back by the first server node, the terminal device does not need to send a connection request to another server node. This helps save resources. In addition, the terminal device may establish a connection to a server node corresponding to received response information, and does not need to wait for feedback from another server node. This helps reduce a delay in establishing a connection between the terminal device and a server node.

  • Patent number: 11222104
    Abstract: A device and a mobile terminal detect that a local end is connected to a peer end by using a data cable. If the mobile terminal detects a first operation action that is performed by a user on a touch display screen of the mobile terminal, the device gains access to the mobile terminal. The device displays a first screen if the mobile terminal detects a second operation action that is performed by the user on an input apparatus different from the touch display screen of the mobile terminal. The first screen is used to prompt the user to enter a screen unlock password of the mobile terminal on the device.
