A method and apparatus for establishing a voice call to a PSTN extension for a networked client computer, and routing the voice call off of the network, is provided. In a first embodiment, the apparatus comprises a storage medium having stored therein a plurality of programming instructions for implementing a set of communication services for facilitating establishment of the voice call to the PSTN extension, and an execution unit, coupled to the storage medium, for executing the plurality of programming instructions. The set of communication services include services for receiving a Push-To-Talk™ request from the networked client computer, requesting the voice call, and in response, determining the PSTN extension. The Push-To-Talk™ request includes identification information of an originating web server of the Push-To-Talk™ option, and the determination of the PSTN extension is made in accordance with the originating web server's identification information.

In accordance with a method and appatatus for synchronization information browsing among multiple systems, a bridgeport system receives identifiers for data requests received in a first hardware system and automatically transmits the identifier of the requested data to one or more additional hardware systems. Each of these one or more additional hardware systems then retrieves the identified data, thereby keeping the data being provided in these hardware systems in synchronization.

A delayed coking process and a solvent deasphalting process are combined so that an asphalt mix of asphalt and solvent from the solvent deasphalting process is sent as feedstock to the delayed coking process to form coke and intermediate hydrocarbon vapor and liquid products. The vaporization of the solvent in a delayed coker heater assists the flow of the asphalt mix through the heater, and a portion of the asphalt mix is directed to a delayed coking fractionator so that the flow of solvent through the delayed coking heater can be adjusted by varying the relative amounts of asphalt mix sent to the delayed coker heater and to the fractionator. A deasphalted oil mix of deasphalted oil and solvent from the solvent deasphalting process is heated by hotter fluid products from a fractionator in the delayed coking process, and makeup solvent to a solvent deasphalting section is heated by vapors in the fractionator overhead. The solvent is recovered from the deasphalted oil mix to yield deasphalted oil, which is stripped in the same vessel as products from the fractionator of the delayed coking process. Condensation of the vapors from the fractionator overhead produces sufficient lean oil that a separate lean oil still may not be required for the economic recovery of coker liquefied petroleum gases. Solvent may be recoverd from the lean oil and naphtha products to supplement the makeup solvent.

A method and apparatus for establishing a voice call to a PSTN extension on behalf of a networked client computer, and routing the voice call off of the network, is provided. In a first embodiment, the apparatus comprises a storage medium having stored therein a plurality of programming instructions for implementing a set of communication services for facilitating establishment of the voice call to the PSTN extension, and an execution unit, coupled to the storage medium, for executing the plurality of programming instructions. The set of communication services include services for soliciting inputs from one or more other apparatuses on one or more operating characteristics associated with the establishment and support of the voice call to the PSTN extension, and selecting either the apparatus itself or one of the other apparatuses to place the voice call to the PSTN extension.

A central processing unit (CPU) is coupled both to a display that displays graphic and other data and to a pointer control device that permits a user to selectively position a pointer at a desired location on the display, and to signal the CPU of user selections. The CPU displays a parent window including a plurality of child windows which comprises a video conference application having a control panel window, a remote window and a local window as child windows. A function in the control panel, identified as a "ungroup" button function, may be selected by a user. The placement of the pointer over the ungroup button function and activation of the button function results in the CPU creating two new top level windows. The CPU reparents the remote and local child windows to the two new top level windows and displays the top level windows with the child windows on the display, thereby ungrouping the three child windows originally disposed within a single top level window. In the multiple window mode, a "group" button function may be selected by a user, the activation of which results in the CPU hiding the top level windows which will lose their child windows in the grouping operation. The CPU then reparents the child windows to a single top window. The remote and local child windows are reparented back to the top level window including the control panel child window. The CPU then displays the single top level window with the associated child windows disposed therein.

The present invention provides a method of quenching heated coke in a coke drum. Quench water is fed into the coke drum to cool the coke, and the stress in the coke drum wall is monitored during the quenching. The rate of feeding the quench water into the coke drum is regulated to prevent the stress in the coke drum wall from exceeding a predetermined limit. The stress is monitored by measuring either the longitudinal thermal gradient or the rates of change in the drum wall temperature over time.
