    摘要： To provide a system for establishing communication that enables reduction of time to establishment of inter-terminal communication and reduces load on server during processing for establishing communication between host terminal and client terminal, during inter-terminal communication after establishment of communication and during reconnection processing.
    Means for Solving the Problem
    A system for establishing communication comprising a host terminal, at least one client terminal, and a server that mediates their communication, wherein the host terminal comprises host side communication request means for sending host terminal information to the server and host side management means for managing client terminal information of individual client terminals, and the client terminal comprises client side communication request means for sending client terminal information to the host terminal and client side management means for managing host terminal information, which system is configured so that, after the host terminal makes a direct session start request to the client terminal based on the client terminal information received from the client terminal, communication is established between the host terminal and the client terminal.

    摘要： The invention relates to the field of construction, in particular to systems for separation of components of the residual concrete mixture. The system for separation of the components of the residual concrete mixture comprises a frame with a rail fixed on it, on which at least one lifting device is placed, which suspends two or more vibrating sieves configured to move horizontally and vertically, as well as to change their angle of inclination, and having different mesh sizes, as well a process tank with a water placed under the vibrating sieves and having upper and lower level sensors controlling the water level in the tank. In a bottom part of the tank there is a pump connected to a conduit of a water distribution system and configured to move a water-cement mixture obtained in the process tank and previously passed through the vibrating sieves. The conduit comprises a movable control nipple configured to determine a cement concentration depending on a density of the water-cement mixture and to direct subsequently the water-cement mixture in the first tank if its density is higher or equal to a predetermined value, or in the second tank, if the density of the mixture is below the predetermined value, through a sand filter, which simultaneously serves as a sand hopper of the sand sifted on the lower sieve; a control unit configured to control an operation of the system for separation of the components of the residual concrete mixture. The technical result is to increase of the operational reliability of the system for separation of the components of residual concrete mixture.
