20130022176 | MULTI-STEP CONTRAST SENSITIVITY GAUGE - An X-ray contrast sensitivity gauge is described herein. The contrast sensitivity gauge comprises a plurality of steps of varying thicknesses. Each step in the gauge includes a plurality of recesses of differing depths, wherein the depths are a function of the thickness of their respective step. An X-ray image of the gauge is analyzed to determine a contrast-to-noise ratio of a detector employed to generate the image. | 01-24-2013 |

20090090307 | ANIMAL PROTECTIVE DEVICE AND METHOD - An animal protective device and method are provided for preventing contact of the animal's head with other parts of the animal. The device includes a body formed in a truncated cone shape. A pressure strap maintains contact with the upper portion and back portion of the animal's head in order to keep the device aligned with the nose and mouth area of the animal. An integral attachment strap is provided that is routed around the neck of the animal to further stabilize the device on the animal. The device may be adjusted at the attachment strap as well as the body to ensure that the device is correctly fitted to the animal. The device is of one-piece construction and does not require use of a separate collar, such as the identification collar of the animal. | 04-09-2009 |

20130292114 | Methods For Containment and Improved Recovery in Heated Hydrocarbon Containing Formations By Optimal Placement of Fractures and Production Wells - A method for containing and capturing liquids and gases generated during in situ pyrolysis that migrate through pyrolysis generated or natural fractures includes placing a row of horizontal hydraulic fractures above and below the heated zone and completing production wells within the horizontal hydraulic fractures. The method serves at least two purposes: 1) provides a local zone of weak mechanical strength to blunt the propagation of vertical pyrolysis generated fractures and 2) provides a drainage point for fluids to relieve pressure in the formation and improve recovery. Preferably, the organic-rich rock formation is an oil shale formation. | 11-07-2013 |

20110244384 | CARBON BLACK GRANULATE, METHOD FOR PRODUCING CARBON BLACK GRANULATE, AND USE THEREOF - The invention relates to carbon black granulates having an APC value, measured at a conveying speed of 8 m/s and a solid load of 27 g/kg, less than or equal to 20 and a 25 [mu]m pressure filter value of less than 5 bar cm2/g. The carbon black granulate is produced by carbon black powder being pre-granulated in a first mixing granulator with addition of a granulation liquid with or without binders and being granulated to a finished state in a second mixing granulator without further addition of granulation liquid. The carbon black granulate can be used as a filler, reinforcing filler, UV stabilizer, conductive carbon black, pigment, or reducing agent. | 10-06-2011 |
