20080251955 | METHOD AND APPARATUS IMPROVING VISION AND THE RESOLUTION OF RETINAL IMAGES - A method of and apparatus for improving vision and the resolution of retinal images is described in which a point source produced on the retina of a living eye by a laser beam is reflected from the retina and received at a lenslet array of a Hartmann-Shack wavefront sensor such that each of the lenslets in the lenslet array forms an aerial image of the retinal point source on a CCD camera located adjacent to the lenslet array. The output signal from the CCD camera is acquired by a computer which processes the signal and produces a correction signal which may be used to control a compensating optical or wavefront compensation device such as a deformable mirror. It may also be used to fabricate a contact lens or intraocular lens, or to guide a surgical procedure to correct the aberrations of the eye. Any of these methods could correct aberrations beyond defocus and astigmatism, allowing improved vision and improved imaging of the inside of the eye. | 10-16-2008 |

20090001308 | Valve to shaft assembly - A valve to shaft assembly includes a butterfly-type valve, a pair of bushings receiving the valve and holding the valve in axial position within a housing, and a shaft engaging the valve and the bushings and rotating the bushings in the housing. The bushings include features to hold the valve in position in the bore prior to assembly of the valve and, furthermore, act as rotating bearing surfaces for the valve. The valve to shaft assembly process may be simplified, especially where multiple valves are assembled to a single common drive shaft, such as in a port face charge motion control valve. Furthermore, the valve to shaft assembly provides an axial degree of freedom between valve, drive shaft, and bore, which allows the valve to float on the axis of the drive shaft, to facilitate self centering of the valve in the valve housing. | 01-01-2009 |

20130192122 | RAPID METHOD FOR PRODUCTION OF CERIUM-CONTAINING OXIDE ORGANIC COLLOIDS - Improved methods for producing colloidal dispersions of cerium-containing oxide nanoparticles in substantially non-polar solvents is disclosed. The cerium-containing oxide nanoparticles of an aqueous colloid are transferred to a substantially non-polar liquid comprising one or more amphiphilic materials, one or more low-polarity solvents, and, optionally, one or more glycol ether promoter materials. The transfer is achieved by mixing the aqueous and substantially non-polar materials, forming an emulsion, followed by a phase separation into a remnant polar solution phase and a substantially non-polar organic colloid phase. The organic colloid phase is then collected. The promoter functions to speed the transfer of nanoparticles to the low-polarity phase. The promoter accelerates the phase separation, and also provides improved colloidal stability of the final substantially non-polar colloidal dispersion. The glycol ether promoter reduces the temperature necessary to achieve the phase separation, while providing high extraction yield of nanoparticles into the low-polarity organic phase. In addition, use of particular amphiphilic materials, such as heptanoic acid or octanoic acid, enable efficient extractions at ambient temperatures without the use of a glycol ether promoter. | 08-01-2013 |
20130197107 | METHOD FOR PRODUCTION OF STABLE CERIUM OXIDE ORGANIC COLLOIDS - An improved process for producing substantially non-polar doped or un-doped cerium oxide nanoparticle dispersions is disclosed.
