Title: Method and apparatus for concurrent dbms table operations
Inventor: MIRZADEH ROSITA
IPC: G06F17/00
Filed: 1999-11-24
Abstract: Database tables are unloaded by launching a number of threads (400) corresponding to a number of export directories (320) located on separate storage devices (310) that maintain the database tables. Each thread is assigned a database table to unload (420). Data unloaded from each database table is stored in a corresponding export directory (320). The data is unloaded from each database table by reading blocks of data from each table and storing the data logs in the export directory (320). Each thread is handled by a separate process in a Symmetric Multi-Processing (SMP) environment. The process is repeated until each database table has been unloaded. The data is then loaded into database tables by first creating a number of temporary tables corresponding to the number of threads (600), reading a set of data stored in the export directory (320) and storing the data in the temporary tables.

Abstract: The invention relates to a valve for admitting atmospheric air into the waste pipe system in response to a pressure reduction in the system in order to protect the water traps in the system and to prevent discharge of contaminated air from the waste pipe system to the atmosphere. The valve consists of a valve body (10) having at least two air inlet openings (30) in communication with the atmospheric air, each of the openings (30) alternating with a passage (14) towards the waste pipe system, said openings and passages (14) being equally distributed within the valve housing (20) when considering a cross-sectional view in a horizontal plane about the valve seat level (H). The valve member (34) resting, in normal closed position, on the valve seat (24) separating said openings (30) from said passages (14) and having a substantially butterfly shaped sealing surface in case of a valve embodiment having two diametrically opposed openings (30) situated perpendicular to respectively two diametrically opposed passages (14). In order to obtain a balanced air distribution within the valve body, the total surface of the air flow passage through the open valve function elements (24, 34, 64) should be substantially equal to the total surface of the air inlet openings (30).

Title: Diamond-coated tool and process for producing thereof
Inventor: LEMMER OLIVER
IPC: C23C28/04
Filed: 2000-03-31
Abstract: The invention relates to a coated component, in particular a coated tool for machining, having a substrate and a first carbon layer, which is applied to the substrate and has a trained fraction of carbon with a diamond crystal structure. There is the problem with such a component that the adhesive strength of the first carbon layer on the substrate is unsatisfactory in many instances. This problem is solved by virtue of the fact that provision is made of a second carbon layer, which is arranged further outside with reference to the substrate than the first carbon layer, and in the case of which the fraction of carbon with a diamond crystal structure is lower than the predetermined fraction of carbon with a crystal diamond structure in the first carbon layer.  The invention also relates to a process for producing such a coated component.

Patent CA-2375505-A1 (CA)
Inventor: COSMAN MAURY D
IPC: C12M3/06
Filed: 2000-06-21
Abstract: The invention features modular cell culturing devices (1) including one or more flat - plate modules (2), and is based on the discovery that if the flows of liquid medium and oxygenated fluid are separated by a gas-permeable, liquid-impermeable membrane, and the cells are grown attached to the liquid side of the membrane, the device can be used to culture cells with transport of oxygen through the membrane (i.e., direct oxygenation), without regard for the flow rate of the liquid medium passing through the device. The new flow-through cell culturing devices (1) can thus be used to culture cells, e.g., hepatocytes, with high levels of cell function in organ, e.g., liver assist systems, for production of cells, for production of cell-derived products, such as proteins or viruses, or for systems to treat biological liquid to remove toxins, such as ammonia, or add cell-synthesized products, or both.

Title: Efficiency enhanced turbine engine
Inventor: WILSON MICHAEL A
IPC: F02C3/14
Filed: 1999-07-19
Abstract: An efficiency enhanced turbine engine and method for a turbine engine having a rotor (25) and a fluid flow path (31) that extends through compression (63), combustion (65), and expansion (67) or turbine stages with fluid flowing through the fluid flow path driving the rotor. The turbine engine has one or more stator-rotor-stator (24-25-24) assemblies, and uses a flat rotor disk with turbine blades (57/58). Capturing of fluid during combustion enables elevation of the temperature and pressure while maintaining the fluid at near constant volume during combustion. Fluid is caused to reenter the rotor a plurality of times to provide cyclic exposure of the moving parts of the turbine engine to different portions of the engine cycle for reducing the average temperature of the moving parts and thereby allow higher compression ratios and combustion temperatures.
Patent CA-2376201-A1 (CA)
Inventor: CLEMENT KATHERINE S
IPC: C08G65/26
Filed: 2000-07-07
Abstract: A poly(ethylene oxide) polymer having low and high molecular weight fractions is fractionated by dissolving the polymer in a solvent for the low molecular weight fraction. A good separation of the low and high molecular weight fractions can be obtained. When the poly(ethylene oxide) polymer contains a metal cyanide catalyst, this process also provides a good separation of the catalyst from the low molecular weight fraction. In this instance, the catalyst remains active and the high molecular weight fraction containing the catalyst can be recycled into subsequent polymerization processes.

IPC: H01T19/00
Filed: 2001-07-06
Abstract: The present invention provides an electrophotographic (EP) image-forming machine and related method having activation of a charger cleaner in a corona charger after an arcing fault. The corona charger has corona wires connected to a high voltage potential supply, preferably providing a voltage in the range of about 5 to 11 kva or in the range of about 13,000 to 22,000 volts peak-to-peak. A corona voltage detection circuit is connected to measure current changes in the high voltage potential supply. A grid has a preselected electric potential to control the charge. The grid may be grounded, but preferably is connected to a power supply providing a voltage in the range of about 300 to 900 volts. A grid voltage detection circuit is connected to measure current changes in the power supply. The voltage detection circuits provide a voltage signal to a microprocessor. When arcing occurs, the microprocessor cycles the EP image-forming machine into a standby mode.     The charger cleaning apparatus is activated to clean the charger. When the cleaning is completed, the EP image-forming machine returns to normal operation. In a further aspect of the present invention, the image-forming process stops when arcing occurs. The charger is cleaned. Any prints affected by the arcing are disposed. The image-forming process restarts at the image frame where the arc occurred.
