20150300501 | MAGNETIC FLUID SEAL WITH PRECISE CONTROL OF FLUID VOLUME AT EACH SEAL STAGE - A magnetic fluid seal includes a pole ring having an inner diameter, a rotatable shaft having an outer diameter, the rotatable shaft configured to extend along the inner diameter of the pole ring between an atmosphere side and vacuum side, at least one magnet coupled to the pole ring, the at least one magnet configured to emit a magnetic field having a strength and a shape, and grooves formed on either the inner diameter of the pole ring or the outer diameter of the shaft, the grooves capable of containing ferromagnetic fluid. The ferromagnetic fluid contained the grooves varies so as to improve the performance of the magnetic fluid seal. | 10-22-2015 |
20130164457 | METHOD OF MANUFACTURING PATTERNED X-RAY OPTICAL ELEMENTS - A pulsed laser beam engraves a groove pattern on substrate of material relatively transparent to the laser beam. The grooves of the pattern are filled with a filling material of different density or different electron density. The pattern of grooves filled with material of different density creates a spatial density modulation that forms the basic structure of various optical elements. By adjusting the flux density of the laser beam to exceed a material break-down threshold only in specific locations, the material ablation can be reduced to a diameter smaller than the diameter of the laser beam itself. The grooves fabricated in this manner can be filled with a deformable material under vacuum with subsequent exposure to air pressure or higher pressure. It is also possible to fill the grooves with nanoparticles of different density and secured by heat application or with a coating. | 06-27-2013 |
20130101091 | Sealed Detector Array for the Collection of Both Wide Angle and Small Angle X-Ray Scattering - A detector system for capturing and resolving WAXS and SAXS beams is provided along with a device for determining structural information of a material incorporating said detector system and a method for examining the structure of a material using said detector system. The detector system generally comprises a sample capable of interacting with the incident x-ray beam, a primary detector and a secondary detector. Upon interaction with a sample of the material, the incident x-ray beam is scattered into wide angle x-ray scattering (WAXS) beams and small angle x-ray scattering (SAXS) beams that are captured by the primary or secondary detectors. | 04-25-2013 |
20120248345 | NANOTUBE BASED DEVICE FOR GUIDING X-RAY PHOTONS AND NEUTRONS - A nanotube based device for guiding a beam of x-rays, photons, or neutrons, includes a beam source and at least one nanotube. Each nanotube has an optical entrance positioned in a manner that a projection of the direction of the central axis at the optical entrance intersects with the beam source. Each nanotube may have an interior diameter that varies along the length of the nanotube. to point the entrances of a bundle of nanotubes toward a point-shaped beam source, the bundle can be grown as an array of multilayer nanotubes from a spherical growth plate. The clear aperture of the bundle is enhanced by providing a smaller number of wall layers of each nanotube near the growth plate than at a distance from the growth plate. | 10-04-2012 |
20110317814 | X-RAY OPTICAL SYSTEMS WITH ADJUSTABLE CONVERGENCE AND FOCAL SPOT SIZE - An x-ray optical system includes a multiple corner optic assembly including an adjustable aperture assembly located in close proximity to the optic assembly. The adjustable aperture assembly enables a user to easily and effectively adjust the convergence of an incident beam of x-rays or the optic focal spot size. The adjustable aperture assembly may further enable a user to condition x-rays of one wavelength and block x-rays of another wavelength and thereby reduce the amount of background radiation exhibited from x-rays of more than one wavelength. | 12-29-2011 |
20110188636 | Multi-Beam X-Ray System - A multi-beam x-ray system includes an x-ray source which emits x-rays and a housing with a first part and a second part. The second part is moveable relative to the first part and includes a plurality of optics of different performance characteristics. Each optic, through the movement of the second part relative to the first part, is positioned to a working position so that the optic receives the x-rays from the x-ray source and directs the x-rays with the desired performance attributes to a desired location. | 08-04-2011 |
