Abstract: Methods, systems, and computer readable media for advertising-supported call service are disclosed. According to one method, a SIP call setup message associated with a first call from a calling subscriber to a called subscriber is received. It is then determined whether the calling subscriber subscribes to a play advertisement pay less (PAPL) service. In response to determining that the calling subscriber subscribes to the PAPL service, an advertisement is presented to the calling subscriber via the subscriber's telephone, the call is connected to the called subscriber, and a reduced charge is effected for the call based on the PAPL service.

Abstract: A method of preparing a composite body comprising a vitreous carbon substrate having a felt prepared from materials selected from the group consisting of metal, carbon and graphite bonded to a major surface thereof, wherein said method comprises(A) forming and curing a branched polyphenylene prepolymer having a number average molecular weight of between about 500 and 800 and bearing terminal acetylene functionality to form a shaped, crosslinked body; (B) preparing a solution of said branched polyphenylene prepolymer in an organic solvent in an amount ranging from about 1 to about 60 parts by weight of said prepolymer per 100 parts by weight of said solution; (C) preparing a composite of said shaped body and said felt to be bonded thereto with said solution interposed therebetween; and (D) firing said composite in an inert atmosphere at a temperature of at least about 800.degree.

Abstract: An improved secondary battery or cell of the type having (A) one or more anodic reaction zones containing a molten alkali metal reactant-anode in electrical contact with an external circuit, (B) one or more cathodic reaction zones containing (i) a cathodic reactant which, when the battery or cell is in the theoretically fully charged state, consists of sulfur and which, when the battery or cell is at least partially discharged, is selected from the group consisting of (a) a single phase composition comprising a molten polysulfide salt of said anodic reactant and (b) a two phase composition comprising molten sulfur and molten sulfur saturated polysulfide salts of said anodic reactant and (ii) an electrode of porous conductive material which is at least partially immersed in said cathodic reactant, and (c) a cation-permeable barrier to mass liquid transfer interposed between and in contact with said anodic and cathodic reaction zones, said porous, conductive material being in electrical contact with both said c
