Abstract: A method for tracking modifications to tables or relationships. In one embodiment, the method includes updating a first value stored in a first field of a record in a table in response to a database system receiving a first structured query language (SQL) statement from a customer relationship management (CRM) application. A first record is inserted into a history table in response to the first SQL statement, wherein the first record comprises a foreign key field that stores a copy of the primary key of the record, a field that stores a copy of the first value after it is updated, a field that stores a name of the first field, and a first date field. The first date field stores either the date when the first SQL statement was received by the database system, the date of the day that immediately follows the date when the first SQL statement was received by the database system, or a date that was entered into a field of a user interface.

Abstract: This invention exploits the concept of Staged Heat and Mass Transfer (SHMT) to enhance operability, control robustness and intrinsic safety in preventing corrosion while recovering material, and energy if desirable, in process waste streams. Two applications illustrating the improvements based on the SHMT concept are given. One application illustrates novel design features to recover vent from a steam boiler deaeration system, positively eliminating the risk of oxygen and carbon dioxide accumulation in deaerator. The other application illustrates process adaptations of the same SHMT concept to recover steam, steam condensate, and fugitive emissions involving particulate materials if desirable, from any process vents from vessels that are opened to the atmosphere. Again, without the risk of corrosion by atmospheric oxygen.

Abstract: This invention pertains to a method for treating a human with human immunodeficiency virus infection which comprises administering to the human a therapeutically effective amount of a thymidine analog, which analog acts as an inhibitor of viral reverse transcriptase necessary for viral replication of human immunodeficiency virus, and a thymidylate synthase inhibitor, or pharmaceutically acceptable salts thereof.

Abstract: A system for separating products from reactants within a reactive distillation column is revealed. Reaction products heavier than reactants are discouraged to re-enter the reaction zone by a rectifying section in between the reaction zone and the stripping section. Reaction products lighter than reactants are discouraged to re-enter the reaction zone by a stripping section in between the reaction zone and the rectifying section.

Abstract: This invention provides cost-effective alternatives to reduce the cost associated with customary blowdown from steam generating equipment. By selectively recycling process blowdown streams using secondary vaporizers, the net result is a partial replacement of wastewater stream with almost an equivalent quantity of clean steam condensate. The heat transfer is carried out by indirect contact devices, such as shell and tube heat exchanger and the like, without mixing of the two process streams to allow condensate recovery while avoiding cross contamination. This invention carries economic as well as environmental credits. A condensate recovery apparatus can be designed to enable easy connection to existing equipment already in service, as well as easy removal, without causing process disruption.

Abstract: A fully thermally coupled distillation structure designed to overcome hydraulic limitations in the past has been revealed for separating a multi-component feed stream into three product streams. The fractionation apparatus is equipped with at least one condenser and one reboiler to provide fractionation efficiency surpassing the PETLYUK system. Further, the fractionation apparatus includes innovative designs to enable hydraulically balanced and energy efficient operation at various feed rates, compositions and product specifications.

Abstract: Embodiments of the present invention are directed to an In-Context Launch Wrapper (ICLW) module which provides a comprehensive generic interface for automating integration of device management applications (applets) into existing Enterprise management console(s) installed at a host system of a network for centralized remote device management of remote network devices on a network.

Abstract: The audio manager provides an interface between one or more upper-level conferencing drivers of the conferencing system and one or more lower-level audio drivers of the conferencing system to isolate the conferencing drivers from the audio drivers. The audio manager is adapted to perform a plurality of functions called by the conferencing drivers. The audio manager comprises a local audio stream state machine and a remote audio stream state machine.

Abstract: Conferencing nodes transmit messages back and forth to negotiate characteristics for their conferencing session. The messages identify different sets of conferencing capabilities supported by the conferencing nodes. A first node transmits a request to a second node, wherein the request identifies a first set of conferencing capabilities of the first node. The second node transmits a response to the first node, wherein the response identifies a second set of conferencing capabilities of the second node and the second set is a subset of the first set. The first node and second node conduct conferencing based on the second set.

Abstract: Two sequences of signal packets are played. Each signal packet of a first type of signals has been stamped with a sequence number corresponding to the position of the signal packet in the first sequence. Each signal packet of a second type of signals has been stamped with a corresponding sequence number of the first sequence. The playing of the second sequence is synchronized with the playing of the first sequence by comparing the sequence numbers of the second sequence to the sequence numbers of the first sequence. In a preferred embodiment, the two types of signals are audio signals and video signals, and the video signal packets are stamped with sequence numbers for the audio signal packets. Each video signal packet of the video sequence is processed for display based on a comparison of the sequence number for the video signal packet and the sequence number for the current audio signal packet.

Abstract: A method is disclosed for the manufacture of a novel chenille upholstery fabric and chenille decorative throw. The chenille yarn contains a continuous filament binder yarn comprising a polymer selected to have a melting point which allows melting to occur at maximum speeds either in a tenter frame or in a heat setting machine. The chenille yarn comprises a pile, a core and the continuous filament binder yarn. The chenille fabric is woven from the chenille yarn and the binder yarn is melted to bind the pile to the core. In one embodiment the melting occurs in a tenter frame during the curing of a latex backing for the fabric. In a second embodiment, the melting occurs in a heat setting machine prior to weaving. As part of both embodiments, the core is air textured together with the binder yarn.

Abstract: A computer system for transmitting two or more types of signals. Each type of signal is assigned a priority level. Signals of a particular type are transmitted as they become ready for transmission, unless signals of a different type having a greater priority become ready for transmission. In that case, the transmission of the low-priority signals is interrupted to allow transmission of the high-priority signals. The transmission of the low-priority signals is resumed after the transmission of the high-priority signals is complete. In a preferred embodiment directed to conferencing systems, audio signals are assigned higher priorities than video, data, and control signals in order to provide a high-quality to the audio portion of a conferencing session.
