Patent CA-2159785-C (CA)
Inventor: AIDA TETSUO

Granted: 2003-04-08
Abstract: The present invention provides a process and equipment for efficiently and economically recovering organic sulfur compounds in a fuel oil while maintaining the original chemical structures thereof.          The fuel oil is admixed with a solvent low in solubility therein of hydrocarbons and high in solubility therein of organic sulfur compounds to effect migration of the organic sulfur compounds in the fuel oil into the solvent by making much of the nucleophilic properties of a lone pair of electrons on a bivalent sulfur atom of a sulfur-containing functional group, followed by fuel oil-solvent separation by settling out or with a centrifugal force.  Alternatively, a solvent having a boiling point not exceeding the boiling point of the fuel oil is added to the fuel oil, and the solvent and the fuel oil are then agitated and mixed together at a temperature of at most the boiling point of the solvent to effect migration of the organic sulfur compounds in the fuel oil into the solvent while lowering the viscosity of the fuel oil, followed by cooling of the fuel oil and the solvent to a temperature not exceeding room temperature and subsequent fuel oil-solvent separation by settling out or with a centrifugal force.  Subsequently, the separated solvent is distilled to recover the organic sulfur compounds.

Title: Call screening method and apparatus for use in completing telephone calls
Inventor: FOLADARE MARK JEFFREY
IPC: H04W84/02
Filed: 1996-07-17
Granted: 2000-01-04
Abstract: A system and method for providing personal communications services are disclosed.  A bridging and signaling unit implements a bridge for connecting telephone calls between a caller, a called party, and an alternate destination.  A caller who calls the personal telephone number associated with a called party is held at the bridging and signaling unit while waiting for a return telephone call from the called party.  The called party is alerted to the existence of the call through a paging system.  If the time period during which the caller is on hold exceeds a time-out period, the caller will be connected to an alternate destination, such as a secretary, an answering service, or a voice messaging system. If the called party places the return telephone call while the caller is connected to the alternate destination, the called party will be connected to the caller and the alternate destination in such a manner that that the called party can hear the conversation between the caller and the alternate destination, but the caller and the alternate destination cannot hear the called party and do not know that the called party has connected, i.e. the called party is on mute mode.  After screening the call, the called party may then indicate that he/she wishes to be connected to the caller, at which time the connection to the alternate destination is terminated and the caller and the called party are connected such that they can speak with each other.  If the called party does not wish to speak to the caller, he/she may hang up, and the connection between the caller and the alternate destination may continue.
