Abstract: A method of reducing the pressure of a liquid includes the steps of providing a conduit containing a packing material, such that a large number of small passages are formed in the packing material, and passing the liquid through the conduit and the packing material. The amount of packing material through which the liquid flows can be varied to vary the pressure drop experienced by the liquid passing through the packing material. The reduction in pressure achieved may be stepwise (discrete) or continuous. The method may be used to reduce the pressure of an aqueous polymer solution for use in a polymer flood technique for oil extraction, and allows the pressure to be reduced without damage to the polymer.

Abstract: Some aspects of the disclosed technology can create a virtual object based on user container selections. Further aspects of the disclosed technology can provide one or more product recommendations corresponding to a current context of user activity. Additional aspects of the disclosed technology can generate and export non-fungible tokens using object recognition. Yet further aspects of the disclosed technology can augment a digital environment with NFT content corresponding to an NFT wallet.

Abstract: An exhaust system component includes a pipe having a pipe wall with an inner surface defining an exhaust gas passage and with an outer surface and a louver bridge portion formed in the pipe wall. The louver bridge portion has bridge ends transitioning from adjacent pipe wall portions to a bridge raised portion with raised side edges detached from adjacent opening side edges of the pipe wall. Each bridge side edge is radially outward of the adjacent opening side edge of the pipe wall to define a louver opening at each of two opposite sides of the louver bridge portion. Fluid communication through the two louvered openings, between the exhaust gas passage and an exterior of the component, attenuates resonant frequencies generated during operation of an exhaust system to which the exhaust system component is connected.
