Abstract:
Provided is a real-time content providing method. The real-time content providing method includes: providing page data to a plurality of user terminals; receiving an action request from a manager terminal or from one or more user terminals; determining a type of the action request; and transmitting action response data to the manager terminal or the one or more user terminals based on the determined type of the action request, wherein the action response data is one of first action response data about a setting change of the page data and second action response data about additional data for updating the page data, and the second action response data is used to request additional response data from a server different from a server determining the type of the action request.
Abstract:
A line card for use in a key telephone system with numerous telephone services provides for electrical isolation between the ring and tip lines and the control circuitry by using a photomodule and blocking capacitor. The control circuitry includes a variable time-out circuit having a plurality of selective resistors, a plurality of NOR gate logic circuits, and a plurality of relays on the card. A zener diode provides a regulated, durable, and surge resistant power supply for the line card, and a light emitting diode provides a positive and continuous indication at the line card of the energization thereof and the seizure of the telephone line.
Abstract:
A PROCESS IS DESCRIBED FOR SIMULTANEOUSLY SCRUBBING FLY ASH AND SULPHUR OXIDES FROM FLUE GASES. THE FLUE GASES ARE TREATED WITH AN AQUEOUS MIXTURE OF A METAL OXIDE HYDROXIDE OR CARBONATE WHICH FORMS A SUSPENSION OF AN INSOLUBLE OR PARTIALLY SOLUBLE METAL SULFITE AND FLY ASH THEREBY REMOVING SAID SULPHUR OXIDES AND FLY ASH FROM THE FLUE GASES. THE INSOLUBLE SULFITE IS CONVERTED TO THE SOLUBLE BISULFITE TO FACILITATE SEPARATION OF THE SOLID FLY ASH AND INSOLUBLE IMPURITIES AND THE SULFUR OXIDE AND METAL OXIDE ARE SUBSEQUENTLY RECOVERED FROM THE BISULFITE SLUTION.
