Inventor: RICHAUD JOHAN
IPC: B22D11/10
Filed: 2002-03-22
Abstract: In the continuous casting of molten metal, the invention describes a refractory article for reducing deposition of inclusions on a surface contacting the stream of molten metal. The article comprises a first composition and a second composition on at least a portion of the contacting surface. The second composition includes a resin-bonded refractory composition comprising a refractory aggregate and a reactive metal.

Title: Automated system for modeling faulted multi-valued horizons
Inventor: VASSILEV APOSTOL TODOROV
IPC: G01V1/30
Filed: 2002-06-05
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.

Title: A universal light-switchable gene promoter system
Inventor: QUAIL PETER H
IPC: C12N1/19
Filed: 2002-08-23
Abstract: An artificial promoter system that can be fused upstream of any desired gene enabling reversible induction or repression of the expression of the gene at will in any suitable host cell or organisms by light is described. The design of the system is such that a molecule of the plant photoreceptor phytochrome is targeted to the specific DNA binding site in the promoter by a protein domain that is fused to the phytochrome and that specifically recognizes this binding site. This bound phytochrome, upon activation by light, recruits a second fusion protein consisting of a protein that binds to phytochrome only upon light activation and a transcriptional activation domain that activates expression of the gene downstream of the promoter.

Filed: 2004-02-23
Abstract: This is game/toy intended for kids from age 6-12 and yet parents are going to have fun as well as there are 3 games that are available. One is self evident as it presents a strike zone for a pitcher. I believe this may be the first net game that does just that.      My other two games can involve a number of people (four is comfortable). All three games are intended to provide a level of accuracy to throwing to a target area. Safety is high as tennis balls are to be used or light foam type balls. My games are unique and are copyrighted.   Many types of throws make this game multi-faceted. Being an out of door game that is easily transportable makes it fun for the cottager as well.      Cheap plastics are not used and the net is heavier cord. The net on this frame will be supported on the ground with extended cpvc legs or into 2 plastic bases that provide the necessary support.

Title: Flat magnetron sputter apparatus
Inventor: CLARKE PETER J
IPC: H01J37/34
Filed: 2002-09-06
Abstract: An electric field is provided in a first direction between an anode and a target having a flat disposition. A magnetic field is provided such that the magnetic flux lines are in a second direction substantially perpendicualr to the first direction. The magnet structure may be formed from permanent magne ts extending radially in a horizontal direction, like the spokes of a wheel, an d from magnetizable pole pieces extending vertically from the opposite ends of the spokes. The permanent magnets and the pole pieces define a well. The target is disposed in the well so that its flat disposition is in the same direction as the magnetic flux lines. Molecules of an inert gas flow through the well. Electrons in the well move in a third direction substantially perpendicular to the first and second directions. The electrons ionize molecules of the inert gas. The ions are attracted to the target and sputter atoms from the surface of the target. The sputtered atoms become deposited o n a substrate. Reflectors in the well near the radially outer walls of the magnet structures, and also in one embodiment near the radially inner walls of the magnet structures, prevent the electrons from striking the permanent magnets. The reflectors and the anode are cooled by a fluid (e.g. water). Th e resultant magnetron sputters as much as 65% of the material from the target on the substrate in contrast to a sputtering of approximately 35% of material from the targets on substrates in the prior art.

Abstract: An apparatus for concentrating and collecting one or more analytes in a flowing liquid stream of a carrier solvent composed of one or more solvent components is provided, which includes a transfer tube which forms a bore having an inlet and an outlet, the inlet being adapted to accept the flowing liquid stream, and the outlet being adapted to form continuously replaced, hanging droplets of the liquid stream, and a collection device mounted below the outlet of the transfer tube for collecting the droplets. The apparatus includes a device for heating the liquid stream in the transfer tube to a temperature sufficient to cause partial evaporation of the carrier solvent from the hanging droplets but not exceeding the boiling point of the carrier solvent, and a device for heating the collection device to a temperature sufficient to cause further evaporation of the carrier solvent from the collected droplets. Also provided is a method for concentrating and collecting one or more analytes in a flowing liquid stream of a carrier solvent composed of one or more solvent components. The method includes the steps of introducing the liquid stream into a transfer tube which forms a bore having an inlet and an outlet, the inlet being adapted to accept the flowing liquid stream, and the outlet being adapted to form continuously replaced, hanging droplets of the liquid stream, and heating the liquid stream in the transfer tube while controlling the temperature of the liquid stream in the transfer tube to be sufficient to cause partial evaporation of the carrier solvent from the hanging droplets without exceeding the boiling point of the carrier solvent. The method allows the droplets to dislodge from the outlet, and the droplet is collected on a collection device mounted below the outlet of the transfer tube. The collection device is also heated to a temperature sufficient to cause further evaporation of the carrier solvent from the collected droplets.
