Abstract: In one aspect, the present invention provides an advertisement distribution system for distributing advertisements to a multiplicity of client devices via a communications network, which system includes at least one ad server that stores the advertisements to be distributed to the client devices, each advertisement being stored in a storage location designated by a source address, and at least one playlist server that provides at least one playlist for each client device. Preferably, the at least one playlist provided for each client device identifies advertisements to be downloaded by that client device.

Abstract: A method for operating a client device that is configured for communications via a communications network includes steps for effecting an advertisement download communication link between the client device and an advertisement distribution server system, via the communications network, at selected advertisement download times, effecting a data communication link with a data communications service provider, via the communications network, wherein the advertisement download communication link and the data communication link are separate communication links, downloading advertisements from the advertisement distribution server system via the advertisement download communication link, storing downloaded advertisements on a storage medium associated with the client device, and displaying at least selected ones of the stored advertisements, in accordance with ad display parameters prescribed by the advertisement distribution server system.

Abstract: A client device that is configured for communications with a multiplicity of other client devices via a communications network, includes a first device for effecting an advertisement download communication link between the client device and an advertisement distribution server system, via the communications network, at selected advertisement download times, a second device for effecting a data communication link with a data communications service provider, via the communications network, wherein the advertisement download communication link and the data communication link are separate communication links, a third device for downloading advertisements from the advertisement distribution server system via the advertisement download communication link, a fourth device for storing downloaded advertisements on a storage medium associated with the client device, and a fifth device for displaying at least selected ones of the stored advertisements, in accordance with ad display parameters prescribed by the advertise

Abstract: A playlist server system for supplying a playlist response to a client device which exchanges information with an information server system and which receives ads from an ad server over a communications network, includes a playlist response generation device for generating a playlist response identifying a plurality of selected ads to be presented by the client device, and a first communications device that effects a playlist response send communications link with the client device via the communications network over which the playlist response is transmitted to the client device, wherein the information server system and the playlist server are independently controlled.

Abstract: A method of operating a regenerative glass furnace for melting glass for the manufacture of shaped glass articles so as to minimize emission of NOx in waste gases leaving the furnace, the furnace having sealed regenerators which act as heat exchangers, the method including supplying fuel in excess of that required for stoichiometric combustion to ensure that glass of the required quality at the required production rate is obtained, and that the waste gases leaving the furnace through the regenerators contain combustible material, and reacting the combustible material with sufficient air to ensure that the waste gases exiting to atmosphere contain permissible levels of combustible material and contain permissible levels of NOx. Alternatively, the furnace may be operated at substantially stoichiometric conditions and fuel is supplied to waste gases as they leave the melting chamber. The invention also relates to a regenerator glass furnace for use in the method.

Abstract: A method of operating a cross-fired regenerative glass furnace for melting flat glass so as to minimize emission of NOx in waste gases leaving the furnace, the furnace having sealed regenerators which act as heat exchangers, the method including supplying fuel in excess of that required for stoichiometric combustion to ensure that glass of the required quality at the required production rate is obtained, and that the waste gases leaving the furnace through the regenerators contain combustible material, and reacting the combustible material with sufficient air to ensure that the waste gases exiting to atmosphere contain permissible levels of combustible material and permissible levels of NOx.
