Title: System and method for minimizing slag carryover during the tapping of a bof converter in the production of steel
Inventor: SHARAN ALOK
IPC: C21C5/28
Filed: 1998-03-30
Granted: 2004-02-17
Abstract: A system and method for detecting molten slag in a tap stream between a steel making basic oxygen furnace (BOF) and corresponding ladle. BOFs are used in the manufacture of steel. An infrared (IR) imaging or detecting device is used to image/view the BOF-to-ladle tap stream, the steam transmitting energy indicative of whether molten steel and/or slag is in the stream at a given time. The imaging device uses mainly long IR wavelengths (e.g. wavelengths of from about 8 to 14 µm) when imaging the molten tap stream, because these wavelengths are less susceptible to being blocked or absorbed by airborne gases and particles frequently found in BOF environments. In certain embodiments, all IR wavelengths other than those greater than about 8 µm are filtered out and are not used to detect slag in the tap stream.

Abstract: We eliminate resin flow into the cells of honeycomb in sandwich structure by using an unsupported film adhesive (108), a barrier layer (110), and a scrim supported adhesive layer (112) between the composite laminate (102) and the core (106). We produce superior panels with lighter weights, improved mechanical properties, and more predictable structural performance by keeping resin in the laminate rather than losing it to the core cells. We reduce core crush and ply wrinkling in composite honeycomb sandwich structure by preventing slipping of tiedown plies relative to the mandrel and to one another during autoclave curing. We produce superior panels with lighter weights, improved mechanical properties, and more predictable structural performance. The method involves applying a film adhesive to the tiedown plies in the margin of the part outside the net trim line. During heating of the autoclave and prior to the application of high pressure to the composite structure, the film adhesive cures to form a strong bond between the plies and to the mandrel. When pressure is applied, the tiedown plies are locked together and to the mandrel to prevent slippage between any layers in the panel.

Abstract: A regenerative thermal oxidizer (10) in which contaminated air is first passed through a hot heat exchange bed and into a communicating high temperature oxidation (combustion) chamber (3), and then through a relatively cool second heat exchange bed. The apparatus includes a number of internally insulated, ceramic filled heat recovery columns (2A, 2B) topped by an internally insulated combustion chamber (3). From the combustion chamber (3), the air flows vertically downward through another column containing heat exchange media, thereby storing heat in the media for use in a subsequent inlet cycle when the flow control valves reverse. Temperature is sensed within the bed of heat exchange media in order to monitor the temperature profile and control a bypass of hot combustion gases should the temperature exceed a predetermined level.

Title: Logical mapping of data objects using data spaces

Granted: 2000-05-09
Abstract: Method and means are provided for simulating a contiguous data space within a computer memory, and for placing and accessing data objects of various sizes within the simulated contiguous data space. Multiple, sub-data spaces are concatenated in such a way that each page and each sub-data space in the contiguous data space are uniquely identified.  Data objects are placed in the contiguous data space and at the first reference to a page of the data object, only the segment containing the referenced page in the contiguous data space is mapped to the database storage disk. Once a data space page is mapped, the operating system can read the page into memory without requesting a disk operation from the database manager. On modifying a page, if the database disk page location is changed, the contiguous data space page is re-mapped without changing the page address in the data space. Also, modified data pages are re-written to the database storage disk in an ongoing manner set by the user, instead of at intervals set by the operating system.
