Title: Direct smelting plant
Inventor: BURROW ANDREW CHARLES
IPC: F27D99/00
Filed: 2001-03-15
Abstract: Direct smelting plant for producing molten metal from a metalliferous feed material induces a smelting vessel 11 to hold a molten metal and slag bath beneath a hot gas space. Solids injection lances 27 extend downwardly and inwardly through side walls of the vessel and hot oxidising gas is directed downwardly into the gas space by a central vertical gas injection lance 26. The plant layout is divided into four functional zones spaced circumferentially around vessel 11 and radiating outwardly from the vessel. Zone 1 contains an overhead hot gas delivery duct 31 supplying gas to lance 26 and an offgas duct 32; Zone 2 contains a forehearth 19 and forehearth tapping launder 34; Zone 3 contains slag notches 45 and slag launders 46; and Zone 4 contains a primary slag drain taphole and launder 48. This layout minimises the potential for interference between the transport of the hot gases, the metaliferous feed material, and the molten metal and slag.

IPC: H04B7/185

Abstract: A comprehensive system and method for uplink power control in a satellite communication system is provided. Power leveling is used to determine a reference uplink transmission power level. That is, the power of uplink signals received by a satellite (140) from a terminal (110) is compared to a power threshold. The transmission power of the uplink signals is then adjusted up or down based on the comparison of the received power with the threshold. Preferably, the power comparison is accomplished using synch bursts. Error leveling is then used to determine a traffic burst uplink transmission power level. That is, once the terminal (110) begins transmitting data using a channel (103), the error rate of the data in the channel (103) is compared to a threshold error rate and the transmission power of the uplink signals is then adjusted up or down based on the comparison. Threshold leveling is then used to evaluate the power threshold. That is, periodically, the reference uplink transmission power level and the traffic burst uplink transmission power level of the channels of the terminals (1101-1105) are compared. The power threshold is then controlled based on the comparison of the reference and traffic burst uplink transmission power levels.

Abstract: A catalytic cracking process includes more than one catalytic cracking step and integrates catalytic cracking steps with hydroprocessing in order to maximize olefins production, distillate quality and octane level of the cracked product. In the process, a hydrocarbon feed is hydroprocessed in a hydroprocessor (23) with thishydroprocessed hydrocarbon being passed to a first catalytic cracking zone (10) to form a first cracked product. This first cracked product is passed to a separator (17) in which hydrocarbon fractions including a gas oil-containing bottoms fraction are separated. This bottoms fraction is then passed to a second hydroprocessor (19) to form a second hydroprocessed hydrocarbon. This second hydroprocessed hydrocarbon is then passed to a second separator (20) to separate a hydroprocessed bottoms fraction and an unspent hydrogen fraction. The unspent hydrogen fraction is combined with the feed and the hydroprocessed bottoms fraction is passed to a second catalytic cracker (11) to form a second cracked product.

Title: Multipoint database synchronization protocol to avoid data corruption
Inventor: NOVAK LARS
IPC: G06Q10/08
Filed: 2000-02-07
Abstract: A database multipoint synchronization which allows mul-tiple clients to simultaneously access and edit a database while avoiding inadvertent data corruption and ensuring the integrity of data within the database. A database manager, which may be configured as part of a database software application, keeps track of modifications saved to a database file and increments a modi-fication change counter accordingly. When a client user accesses a database record, the database manager detects the modification change counter value. Then if that client seeks to save mod-ifications to the database record, the database manager detects the current modification change counter value to discern whether other clients have saved modifications to the record following the access by the client presently seeking to save modifications.  If the modification change counter has incremented, the client is denied authorization to save the modifications and offered a choice of alternative operations. In this way, the data within the database record is not corrupted due to inadvertenly overwritting by another client's record.
