Abstract: 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.

Abstract: A compound of formula: ##STR1##

Abstract: An apparatus and method for displaying caller identification information in a computer system. The present invention is a caller identification system for displaying caller information, the system comprises: 1) a telephone interface for receiving an incoming call from a caller, the telephone interface further receiving information indicating a caller telephone number corresponding to the caller, 2) logic for searching a caller information database for caller information corresponding to the caller telephone number, the caller information including at least the caller telephone number and a caller name, 3) logic for retrieving the caller information, and 4) logic for automatically displaying the caller information without user intervention. The caller identification system of the present invention includes logic for automatically displaying the caller information in a business card format.

Abstract: A process and apparatus for the recovery of oil from aqueous oil refinery waste involves mixing the waste with a fluidizing oil and evaporating the water from the mixture in a plurality of stages. The dewatered mixture is fed to a delayed coking system in which a conventional coker feedstock is being used. The heavy hydrocarbon portion of the dewatered mixture changes to coke and light hydrocarbon material, the inert solids become trapped in the coke, and the fluidizing oil vaporizes. A stream of heavy coker gas oil is fed from a fractionator in the delayed coking system to a fluidizing tank where it is mixed with the sludge to define the fluidizing oil. Another hot stream of hydrocarbon material from the coker fractionator is sent to the evaporator section to provide the heat for evaporation.

Abstract: A method for conditioning delayed coke includes allowing coke to form in a first chamber or coke drum, while simultaneously conditioning coke in a second coke drum by flowing through it a hydrocarbon conditioning fluid recirculated from another portion of the coking apparatus, said conditioning fluid having a temperature of more than 750.degree. F. and less than 1000.degree. F., and decoking a third coke drum. The coking, conditioning and decoding operations are sequentially switched among the coke drums.

Abstract: 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.

Abstract: 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.
