20140306069 | Method and Apparatus for Retaining Elevated Objects - An apparatus for retaining and securing elevated objects such as cement valves. A harness member is wrapped around the outer surface of an elevated object, and adjustable straps are tightened to secure the harness member in place. An elongate sling member, attached the harness member, is securely attached to a cement head assembly or other nearby support structure. The apparatus provides positive retention should an elevated object become detached, thereby preventing the object from falling and injuring personnel or damaging property. | 10-16-2014 |

20150071843 | Nanofilaments of Catalytic Materials for Chemical Process Improvements - A Haber-Bosch process including the steps of providing a reactor having a substrate with catalyst filaments formed thereon. The catalyst filaments are formed of a metal including iron. A nitrogen compound and hydrogen are injected into the reactor such that at least a portion of the nitrogen compound and hydrogen contact the catalyst filaments. The nitrogen compound and hydrogen are reacted with the catalyst filaments at a temperature of less than about 600° F. and a pressure of less than about 2000 psig. | 03-12-2015 |

20150075242 | FRICTION-STIR EXTRUDERS AND FRICTION-STIR EXTRUSION PROCESSES - A friction-stir mandrel includes a textured end portion integral with a body portion. The textured end portion is configured to friction-stir process a starting material forced across the textured end portion and through a die in a plasticized state to form a pipe. A pipe can be formed by forcing a starting material across a textured end of the mandrel and through a die in a plasticized state, so that the textured end of the mandrel breaks up existing grains of the starting material. The pipe is formed from material that is forced through the die. The friction-stir mandrel can be used with porthole die friction-stir extrusion, seamless tube friction-stir extrusion, and tube friction-stir drawing processes to provide tubing in which the grains are broken up by the textured portion of the friction-stir mandrel. The textured portion can include features, such as threads, ridges, studs, protrusions, and the like. | 03-19-2015 |

20120061586 | Method and detection system for detection of aflatoxin in corn with fluorescence spectra - A system and method for fluorescence spectral imaging of target material to detect the presence of a contaminant (such as aflatoxin in corn) is provided. An ultraviolet light source is coupled a light-excluding compartment. The fluorescence from the UV excited target passes through a filter (liquid crystal tunable, acoustic-optic tunable, a filter wheel, or other wavelength splitting device) and a lens, to a spectral imaging camera. Fluorescence spectral image data from the camera is analyzed by a computer and presented in human-readable form. Aflatoxin detection in contaminated corn kernels is based on peak fluorescence and peak fluorescence shift in the spectral range from 451 nm to 500 nm. Aflatoxin contamination level within the target material is quantified based on peak fluorescence and peak fluorescence shift and computed corn kernel pixel statistics. | 03-15-2012 |

20140348740 | DEVICE FOR MIXING AND COOLING TWO REACTIVE LIQUIDS AND METHOD OF MAKING PEROXOMONOSULPHURIC ACID WITH THE DEVICE - A device for mixing and cooling two reactive liquids, comprising a bundle type heat exchanger with parallel tubes, a head space open to one end of all tubes, a first inlet to the head space for introducing a first liquid and a second inlet to the head space with a multitude of nozzles for introducing a second liquid, the nozzles being located within the head space and oriented to direct the introduced liquid transverse to the axis of the tubes of the tube bundle, is useful for making peroxomonosulphuric acid from 85 to 98% by weight sulphuric acid introduced into the first inlet of the device and 50 to 80% by weight aqueous hydrogen peroxide introduced into the second inlet of the device. | 11-27-2014 |
20140369906 | ENRICHMENT OF METAL SULFIDE ORES BY OXIDANT ASSISTED FROTH FLOTATION - The present invention is directed to methods that can be used in the enrichment of metal sulfide ores in desired minerals in cases where the ores have sulfide-containing gangues. The method involves adding an oxidant to slurries prepared from the ores during, or immediately prior to froth flotation. | 12-18-2014 |
