Patent EP-1099290-B1 (EP)
Inventor: UNDERWOOD THOMAS C
IPC: H02J3/40
Filed: 1999-08-26
Granted: 2003-04-23
Abstract: An integrated system for comprehensive control of an electric power generation system utilizes state machine control having particularly defined control states and permitted control state transitions. In this way, accurate, dependable and safe control of the electric power generation system is provided. Several of these control states may be utilized in conjunction with a utility outage ride-through technique that compensates for a utility outage by predictably controlling the system to bring the system off-line and to bring the system back on-line when the utility returns. Furthermore, a line synchronization technique synchronizes the generated power with the power on the grid when coming back on-line. The line synchronization technique limits the rate of synchronization to permit undesired transient voltages. The line synchronization technique operates in either a stand-alone mode wherein the line frequency is synthesized or in a connected mode which sensed the grid frequency and synchronizes the generated power to this senses grid frequency. The system also includes power factor control via the line synchronization technique or via an alternative power factor control technique. The result is an integrated system providing a high degree of control for an electric power generation system.

Granted: 2003-03-26
Abstract: A microprocessor (10) incorporating a modified Harvard architecture connected to two memory banks (100) and (114). The main CPU also includes two pushdown stacks (104, 108). One of the stacks has its top two items connected directly to an arithmetic-logic unit (103). In addition hardware is provided to perform seven operations on the top three stack elements. The instruction length of the microprocessor is 8 bits and most instructions execute in a single clock cycle. A unique feature of the instruction set is that 128 of the 256 possible bytecodes are user-programmable. Some regular instructions can be "folded" with the "return from subroutine" instruction. This allows the efficient implementation of a wide variety of virtual machines, such as the Java Virtual Machine. The microprocessor also contains dedicated registers and circuits for the efficient implementation of dynamic variables (112), 32-bit immediate constants (109 and 110), interfaces to dedicated co-processors and interfaces to local area networks allowing dynamic upgrades of application software.

Title: Portable bending machine for light metal sections
Inventor: BRUNETTA BRUNO
IPC: E04C/
Filed: 1995-10-09
Granted: 1997-12-18
Abstract: The technological sector to which the invention relates mainly concerns that of construction, in particular that of the infrastructure required in order to support plasterboard work. Such work is often performed with shapes having a curvilinear surface and therefore suitably shaped structures (metal frames) are required. This equipment makes it possible to bend the structure's section on site from a minimum radius of 300 mm to infinity without any break in continuity. This innovation helps plasterers in that there is no risk of calculating incorrect radiuses of curvature, as the radius can be adjusted by testing directly on site and the number of arched profiles necessary can quickly be made immediately, avoiding loss of time and waste. <IMAGE>

Abstract: En vandig oppløsning av fritt hydroksylamin. fremstilles ved behandling av et hydroksylammoniumsalt med ammoniakk ved hjelp av motstrømsmetoden i en strippekolonne ved hjelp av en fremgangsmåte hvori hydroksylamin frigis og sam- tidig den oppnådde oppløsning separeres ved destillasjon i en vandig hydroksylaminoppløsning og en saltfraksjon. Den nye fremgangsmåte kan gjennomføres på en enkel og skånsom måte og i en større målestokk. Faren for spalting ned- settes til et minimum på grunn av den lave termiske belastning, den lave konsentrasjon av hydroksylamin og den korte oppholdstid i prosessen.

Abstract: In a method for modeling a reservoir having a horizon surface with a reverse fault, a volume of the reservoir is partitioned into fault blocks. A bounding surface of each of the fault blocks includes a portion of the reverse fault. The interior of each of the fault blocks includes only single valued horizon surfaces. Horizon data describing the reservoir is partitioned into patches, each patch corresponding to a fault block. A horizon surface patch model is derived from the data patch in the interior of each fault block. The horizon patch model includes an up-thrown or down-thrown fault trace, which defines the intersection of the surface patch with the bounding reverse fault. Continuity constraints are defined to ensure that horizon surface patch models on the opposite sides of the reverse fault coincide outside of the real fault.
