20080314896 | FOLDABLE PART HOLDER - A preferred embodiment of the foldable part holder is comprised of a front flap, a bottom flap, a back flap, a top flap, a prong flap, a plurality of folds, a plurality of slots, and a plurality of apertures all of which are formed from a flat sheet of polymeric material. The front flap, the bottom flap, the back flap, the top flap, the prong flap, the plurality of folds, the plurality of slots, and the plurality of apertures are all arranged on the flat sheet such that when the flat sheet is folded along the plurality of folds, the embodiment forms a three-dimensional part holder. The plurality of folds are formed by the polymeric sheet such that when folded the flaps engage each other in the appropriate manner. All of the elements formed onto the flat sheet of polymeric material through any fabrication process common for polymeric materials. | 12-25-2008 |

20090086898 | ANALYTICAL X-RAY TUBE FOR CLOSE COUPLED SAMPLE ANALYSIS - An x-ray device and method useful in performing close coupled sample analyses. The x-ray device includes an evacuated enclosure having a window and in which is disposed a cathode assembly, control grid, insulator, and anode arranged so that the anode is interposed between the electron source and the window. The anode includes a target surface oriented toward the window and the anode defines a drift tunnel which is substantially aligned with a hollow defined by the insulator. The control grid can be used to influence the energy of the electrons emitted by the filament of the cathode assembly. A high voltage field between the anode and filament causes electrons emitted by the cathode to accelerate rapidly through the insulator. After accelerating to an energy level consistent with the high voltage field, the electrons then pass through the drift tunnel without gaining any additional appreciable energy. The potential difference between the target surface and the window causes the drifting electrons to decelerate, and eventually stop, before they can strike the window. The decelerated electrons then re-accelerate, under the influence of the potential between the window and the anode, toward the target surface, striking the target surface and producing x-rays which are directed through the window so as to impact a sample. One or more detectors proximate to the sample sense the characteristic response emitted by the sample when it is struck by the x-rays produced by the x-ray tube. A computer in communication with the detectors facilitates processing and analysis of the characteristic response sensed by the detectors. | 04-02-2009 |
20090129550 | FILAMENT ASSEMBLY HAVING REDUCED ELECTRON BEAM TIME CONSTANT - A filament assembly for use in an x-ray emitting device or other filament-containing device is disclosed. In one embodiment, an x-ray tube is disclosed, including a vacuum enclosure that houses both an anode having a target surface, and a cathode positioned with respect to the anode. The cathode includes a filament assembly for emitting a beam of electrons during tube operation. The filament assembly comprises a heat sink and a plurality of filament segments. The filament segments are configured for simultaneous emission of an electron beam for impingement on the target surface of the anode, and are electrically connected in series. Each filament segment includes first and second end portions that are thermally connected to the heat sink, and a central portion that can be configured with a modified work function for preferential electron emission. | 05-21-2009 |

20120114104 | ASYMMETRIC X-RAY TUBE - An asymmetric x-ray tube. In one example embodiment, an x-ray tube includes an evacuated enclosure, a cathode assembly at least partially positioned within the evacuated enclosure and defining a first axis, and an anode assembly at least partially positioned within the evacuated enclosure and defining a second axis. The anode assembly includes a rotating anode having a focal spot. The focal spot and the second axis define a plane. The first axis is positioned beneath the plane. | 05-10-2012 |
20130182825 | X-RAY TUBE CATHODE WITH MAGNETIC ELECTRON BEAM STEERING - An x-ray tube cathode with magnetic electron beam steering. In one example embodiment, an x-ray tube cathode includes a cathode head and an electron emitter. The cathode head includes electrically conductive and non-magnetic material integrated with magnetic material. The cathode head defines an emitter slot in a portion of electrically conductive and non-magnetic material positioned between two portions of magnetic material. The electron emitter is positioned within the emitter slot. The electron emitter is configured to emit a beam of electrons. The beam of electrons is configured to be both focused by the electrically conductive and non-magnetic material and steered during beam formation by the magnetic material. | 07-18-2013 |
20140105366 | FINNED ANODE - Finned anode. In one example embodiment, an anode suitable for use in an x-ray tube includes a hub, a front side, and a target surface disposed on the front side. The hub is configured to attach to a bearing assembly and the front side substantially faces the bearing assembly. The anode further includes a rear side substantially opposite the front side, as well as two or more annular anode fins extending from the rear side. The annular anode fins are positioned radially outward from the hub to an outer periphery of the rear side. | 04-17-2014 |

20100215551 | Tyer hot gas filter and fluidized bed media cleaner - The gasifier described includes, in its preferred embodiments, a vertically elongated (“oblong”) primary gasifier chamber with an auger and a fluidized bed, allowing for large amounts of fuel input when necessary. The gasifier further includes a gas treatment chamber receiving gases discharged from the gasifier chamber. The fluidized bed in the gasifier chamber as well as the gas treatment chamber contain metallic particles, with these metallic particles circulating in a closed loop between the gasifier chamber and the gas treatment chamber. This system offers numerous benefits. Some or all of said metallic particles can serve as a catalyst in the gasification of the gasifiable materials being processed, including serving as a catalyst for a Fisher Tropsch chemical process in the gasification of said gasifiable materials. In the gas treatment chamber particularly, some or all of said metallic particles serve to clean gases produced in the gasification of said gasifiable materials. The metallic particles can have sizes chosen to provide ate least one of a selected contact area for gases in the gas treatment chamber, and a selected limit on backpressure for an adequate gas stream flow to gas stream cleaning ratio. Also, the metallic particles have a heat retention capacity and this heat retention capacity serves to stabilize the operating temperature of the gasifier. The metallic composition of the metallic particles keeps them from becoming entrained in the gases being discharged from the gasifier chamber, and it is also possible to use the metallic composition of the particles to magnetically separated them from ash issuing from the gasifier chamber (as part of their closed loop circulation). In this circulation, the metallic particles pick up residues in the gas treatment chamber (cleaning the gases passing therethrough), and are cleaned in turn when they pass back through the gasifier chamber. Finally, the overall system allows an oxygen deprived environment and an elevated pressure to be maintained in said gasifier chamber during the closed loop circulation of metallic particles between the gasifier chamber and the gas treatment chamber, promoting maximum efficiency in the gasification process. | 08-26-2010 |
