Title: Flexible window management on a computer display
Inventor: DAWES ANTONY J O
IPC: G06F3/048
Filed: 1988-08-19
Granted: 1992-06-09
Abstract: ABSTRACT      A technique is described for managing windows in a display system.  The window manager allows a user to mark an area on the display to define the dimensions and contents of a resized window.  All non-hidden text and attributes within the enclosed area are incorporated into the resized window; however, the original windows do not lose their original characteristics.  The marked area may span multiple windows, so multiple windows may be incorporated into the newly resized window.  For each position within the newly resized window, a check is made for a window below.  If no window exists below this position, the default, or background, character and attribute are incorporated into the newly resized window.  If there exists a window below, a determination is made as to whether the window below is visible or hidden.  If hidden, the system continues to look for a visible window until no further window is found below, at which point the default character and attribute are incorporated into the newly resized window.  When a visible window is found below the newly resized window, the character and attribute from its corresponding position and read and incorporated into the newly resized window. This process continues until all of the information is processed from the marked area. In this manner; a window can be enlarged to incorporate the contents of several windows by enclosing several windows in the marked area.

Title: Process for detoxifying a bottoms draw-off from a high temperature chlorination reactor
Inventor: SCHNEIDER WOLFGANG W
IPC: A62D3/00
Filed: 1989-01-16
Granted: 1993-02-23
Abstract: PROCESS FOR DETOXIFYING A BOTTOMS DRAW-OFF FROM A HIGH TEMPERATURE CHLORINATION REACTOR                 ABSTRACT OF THE DISCLOSURE Under certain operating conditions, an emulsion of an acidified unfiltrable tarry bottoms stream from a reactor for the chlorination of ethylene to 1,2-dichloroethane can be demulsified and separated in a phase separation tank. The presence of FeC13 in an amount more than 5 ppm Fe in the separated organic waste, fouls the reboiler and lower internals of a "heavies" column in which the separated organic waste is concentrated, and deactivates the cata-lyst in a Catoxid fluid bed reactor in which the concen-trate is burned. By maintaining an iron salt chlorination catalyst in a concentration which results in 2000 ppm to 4000 ppm of Fe in the HTC reactor bottoms, and operating the HTC reactor at a temperature in the range from about 90°C to 120°C and a pressure in the range from 9 psig to 12 psig, an unfiltrable reactor bottoms drawoff is produc-ed which may be acidified without forming an emulsion. Formation of an emulsion is avoided by mixing each volume of the HTC bottoms drawoff with at least 50 volumes of dilute aqueous HCl in a concentration range from 2 to 4% so as to demulsify the emulsion into aqueous acid and organic phases. The mixture is gravity-separated in a phase separation tank by decantation. The lower layer (60-70% by wt EDC, the remainder being heavies) is concentrat-ed by recovering EDC overhead and producing a bottoms concentrate in which the Fe is present in no more than 50 ppm. The concentrate may be economically disposed of in a Catoxid reactor using a support free gamma alumina cata-lyst found to be highly sensitive to iron.

Abstract: Abstract of the Disclosure A top  open ball  valve assembly  which in-cludes a pair of camming plates,  one at the top and one at the bottom of the plug.  The camming plates are oval and in their minor axis are clear of the floating valve seats.  There are lost motion slots to allow the plug to travel between an open and closed position without moving the camming plates.  In the event it is required to  retract the  valve  seats,   the  plug  is rotated more than 90°  so as  to engage the camming plates to move them so that the major axis of the oval camming plates is aligned with the flow passage of the inlet and outlet ports,  and the camming plates engage and retract the floating valve seats.  Annular grooves are provided in the valve seat recess and in the valve seat whereby they are radially aligned when the valve seats are retracted,  and an elongated coil spring can be inserted in the passage formed by the grooves to block the valve seats in their retracted position.
