Abstract:

This disclosure provides for alpha olefin oligomers and polyalphaolefins (or PAOs) and methods of making the alpha olefin oligomers and PAOs. This disclosure encompasses metallocene-based alpha olefin oligomerization catalyst systems, including those that include at least one metallocene and an activator comprising a solid oxide chemically-treated with an electron withdrawing anion. The alpha olefin oligomers and PAOs prepared with these catalyst systems can have a high viscosity index combined with a low pour point, making them particularly useful in lubricant compositions and as viscosity modifiers.

US Classification:

585 18, 585520, 585533

Abstract:

This disclosure provides for olefin wax oligomer compositions, methods of producing olefin wax oligomer composition, and methods for oligomerizing olefin waxes. This disclosure encompasses metallocene-based olefin wax oligomerization catalyst systems, including those that include a metallocene and an aluminoxane, a metallocene and a solid oxide chemically-treated with an electron withdrawing anion, and a metallocene, a solid oxide chemically-treated with an electron withdrawing anion, and an organoaluminum compound. The olefin wax oligomers prepared with these catalyst systems can decreased needle penetrations, increased viscosity, and an increased drop melt, making them useful as an additive in candles, stone polishes, liquid polishes, and mold release formulations.

Appl. No.:

12/958385

Inventors:

Qing X. Yang - Hummelstown PA, US

International Classification:

A61B 5/055
G01R 33/48
G01R 33/28

US Classification:

600420, 324318

Abstract:

Layers or coats of materials with high dielectric constant or permittivity with very low conductivity are inserted in between radiofrequency (RF) coil or coil's conductive elements and the sample to enhance the signal to noise ratio (SNR), improve image contrast, and reduce the specific absorption rate (SAR) of magnetic resonance imaging or magnetic resonance spectroscopy instruments. The embodiments of the present invention can be used as an auxiliary device to the standard pre-constructed RF coils or incorporated with RF coil constructions for enhancing RF coil performances in both transmission and reception.

International Classification:

G01R 33/565
A61B 5/00
G01R 33/28
A61B 5/055

Abstract:

A method for enhancing the performance of an imaging system that includes providing a magnetic resonance imaging system; providing an object to be imaged, wherein the object has a shape, includes a region of interest therein, and has a first dielectric constant; providing a pad that conforms to the shape of the object and contains a material having a second dielectric constant that is higher than the first dielectric constant; surrounding the pad and the object being imaged with at least one radio frequency coil; using the at least one coil to generate a magnetic field having an intensity of 3 T that extends through the material of the pad and into the region of interest of the object being imaged, and wherein positioning the at least one coil to surround the pad and the object increases the intensity of the magnetic field produced by the at least one coil within the region of interest of the object; using the at least one coil to detect the magnetic field generated in the region of interest of the object being imaged and to convert the detected magnetic field into detectable electrical signals; and increasing signal to noise ratio of detected electrical signals and decreasing required power input to the at least one coil through the placement of the at least one coil around the pad.
