Title: Catalytic metal additive concentrate and method of making and using
Inventor: VALENTINE JAMES
IPC: C10L1/18
Filed: 2003-03-21
Abstract: Delivery of metallic combustion catalysts to internal combustion engines and other combustion devices is improved by dosing units that have the ability to effect the slow and positive supply of metallic additives, including platinum and/or cerium containing catalyst compositions, to fuel. The invention provides additive dosing materials and methods for simply and effectively supplying catalytic metal fuel additives to fuel in suitable low concentrations as are effective. The dosing units can be used with devices made to contact diesel fuel. In one approach, a catalytic metal additive concentrate (CMAC) is prepared in normally solid, semisolid or viscous form.  The CMAC will preferably be encapsulated with a solid polymer. The encapsulation can be accomplished by embedding or dispersing the CMAC in a suitable polymer. If desired, the CMAC can be dispersed in one polymer and then the resulting composite can be embedded in the same or a different polymer. In an alternative form, a dosing unit can comprise a semisolid CMAC, which could be similarly held in contact with flowing fuel.

Abstract: The present invention provides a seismic exploration and imaging system for producing seismic survey reports of subsea geological structures. The exploration system provides a method in which both P-waves and S-waves are detected without the need for placing detection apparatus in contact the seabed. A seismic event is applied (12) to the earth~s surface (13), and the detected response including P-waves and S-waves in the earth~s. The detectin g apparatus comprises a means for monitoring and recording the response to the seismic event in the form of movements of particles at the earth~s surface, from a position spaced from the earth~s surface. Particles at the surface wi ll respond both to P-wave and S-wave stimulation and so their movements will be representative of the two waves. These movements are detected from a distanc e.

Title: Light emitting diode package providing phosphor amount control
Inventor: SCHERBAKOV VALENTIN
IPC: H01L33/50
Filed: 2004-02-11
Abstract: Light emitting diodes are prepared with specialized packages which provide a dosing feature with respect to a phosphor wavelength converting medium.  Elements of the device package form a specially shaped cavity when coupled together. The shape and size of the cavity operates to control the dosing of phosphor spiked medium of soft gel. The gel fills the cavity such that light emitted from a semiconductor die is exposed to a similar cross section independent of the exact direction of light propagation. In this way, 'white' LED systems are formed from blue emitting diodes as highly controlled phosphor dosing permits precise amounts of blue light to be converted to yellow light without problems with angular uniformity observed in competing technologies.

Inventor: GIVENS GEORGE E
IPC: E21B33/04
Filed: 2000-09-29
Abstract: A liner hanger assembly has a slip actuation system which is locked for run- in. A piston assembly bolts onto the mandrel in a sealable manner to actuate a mechanical lock. Upon release of the lock, a plurality of springs actuate a sleeve which is in turn attached to the slips to move them relative to their slip seats. The slip seats are preferably mounted to the mandrel without welding and have longitudinal spaces for mud or cement flow therebetween. Load is distributed from each slip through its slip seat into the mandrel without interaction from an adjacent slip or slip seat. A rupture disk ensures that a predetermined pressure is built up before the piston can actuate to defeat the lock. The lock can come in a variety of configurations. One of which is a sliding sleeve over a dog and another is a yoke over a split ring which, when shifted, allows the split ring to expand, thus unlocking the parts. The slips can also be configured to allow flow of mud or cement behind them, thus reducing the resistance to flow of such materials.
