Abstract: A system includes a server that converts proxies of assets into virtual assets and hosts a session to exchange the virtual assets independent of users to which the proxies belong. The server can perform a decoupled asymmetric exchange based on the virtual assets over one or more network links between a user device and the server and between the user device and an issuer of the proxies. An agent server is delegated by the server to authorize the decoupled asymmetric exchange and route communications over the separate network links based on one or more conditions being satisfied. The system can then allocate the assets to the user device, independent of the users to which the proxies belong.

Abstract: A system can receive an indication from a user of a user device to participate in a session of an electronic exchange. The indication includes an indication of interest to perform a transaction with a participant of the temporary session. The system can predict, as an output of a machine learning (ML) model, a range of values for a valuation of the asset, receive an indication that the user selected a particular value of the range of values to configure a first side of the transaction, and automatically match a second side for the transaction with the first side of the transaction. The system further can perform an exchange of the asset between the first side and the second side of the transaction based on the particular value of the range of values.

Abstract: A welding torch tip for use in welding ferrous metals with Mapp gas, and method for same. The tip is elongated and has threads in one end thereof and a gas outlet in the other end thereof and it has a gas mixing chamber centrally located in the tip and intermediate the screw threads and the outlet. The method is the steps of introducing the gas into the tip and mixing the gas in a chamber in the tip and then directing the gas through a passageway and out of the tip.
