| 20110042084 | IRREGULAR PATTERN TREATMENT OF A SUBSURFACE FORMATION - A method of heating a subsurface hydrocarbon containing formation includes providing heat flux per volume to a first portion of a subsurface hydrocarbon containing formation. The heat flux per volume is provided by two or more first heat sources positioned in the first portion. Heat flux per volume is provided to a second portion of the subsurface hydrocarbon containing formation with the heat flux per volume being provided by two or more second heat sources positioned in the second portion. The heat flux per volume provided by the two or more second heat sources is greater than the heat flux per volume provided by the two or more first heat sources. The second portion is positioned below the first portion. | 02-24-2011 |

| 20090119047 | QUALITY ASSURANCE SYSTEM AND METHOD FOR POINT-OF-CARE TESTING - An improved quality assurance system and method for point-of-care testing are disclosed. The present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care without the need for running liquid-based quality control materials on the analysis system. Quality assurance of a quantitative physiological sample test system is performed without using a quality control sample by monitoring the thermal and temporal stress of a component used with the test system. Alert information is generated that indicates that the component has failed quality assurance when the thermal and temporal stress exceeds a predetermined thermal-temporal stress threshold. Alternatively, the present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care by minimizing the need for running liquid-based quality control materials on the analysis system. | 05-07-2009 |

| 20100252286 | METHOD AND APPARATUS FOR HARVESTING AND PICKING UP SOD - A method of harvesting and handling sod includes cutting an elongated sod slab and cutting said sod slab into two sod sections, but leaving uncut at least one small sod connection between said two sod sections, thereby to tie together said sod sections in a stack containing said sod sections. | 10-07-2010 |
| 20110100275 | METHOD AND APPARATUS FOR IN SITU TREATMENT OF GRASS - An apparatus for spraying a treatment liquid onto grass growing on a ground surface includes a plurality of rotatable discs spaced laterally apart across the path of travel. Each disc has a plurality of cutters which are adapted to penetrate the ground surface and to cut holes therein as the apparatus travels forwardly. The holes are spaced apart along the path of travel and are also spaced apart laterally. The apparatus also includes a set of nozzles positioned on the apparatus above the grass such that each nozzle is spaced rearwardly along the path of travel from its associated disc but is aligned along the path of travel with such disc. The nozzles are adapted to spray the treatment liquid. The apparatus also including a controller for causing the nozzles to spray the treatment liquid into the holes. | 05-05-2011 |

| 20090071573 | PHOSPHATING SOLUTION WITH HYDROGEN PEROXIDE AND CHELATING CARBOXYLIC ACIDS - The invention relates to a phosphating solution and a process for the phosphating of metallic surfaces with aqueous, acidic phosphating solutions that comprise zinc and phosphate ions, at least one source of peroxide and one or more aliphatic chelating carboxylic acids containing 2 to 7 carbon atoms; the phosphating solution having a free acid content of one point or less. | 03-19-2009 |
| 20090255608 | ZR-/TI-CONTAINING PHOSPHATING SOLUTION FOR PASSIVATION OF METAL COMPOSITE SURFACES - The present invention relates to an aqueous composition and to a method for the anticorrosion conversion treatment of metallic surfaces, particularly metallic materials which are assembled into composite structures, comprising steel or galvanized or alloy-galvanized steel and any combinations of these materials, the composite structure being composed at least in part of aluminum or the alloys thereof. The aqueous composition according to the invention is based on a phosphating solution and contains, in addition to water-soluble compounds of zirconium and titanium, a quantity of free fluoride in a ratio that both permits phosphating of the steel and galvanized and/or alloy-galvanized steel surfaces and determines low pickling rates with regard to the aluminum substrate with simultaneous passivation of the aluminum. The metallic materials, components and composite structures conversion treated in accordance with the underlying invention are used in automotive body construction, in shipbuilding, in construction and for the production of white goods. | 10-15-2009 |
| 20090288738 | PROCESS FOR OBTAINING DESALTED WATER FROM ZIRCONIUM-CONTAINING WASH WATER - A method for recovering demineralized water from zirconium-containing rinse water having a pH lower than 6.0, wherein a) the rinse water has added to it an aqueous solution of Ca(OH) | 11-26-2009 |
| 20110041957 | OPTIMIZED PASSIVATION ON TI/ZR-BASIS FOR METAL SURFACES - The present invention relates to a chromium-free aqueous agent based on water-soluble compounds of titanium and/or zirconium and a source of fluoride ions, copper ions and metal ions selected from the group consisting of calcium, magnesium, aluminum, boron, zinc, iron, manganese and/or tungstene and to a method for the anti-corrosive conversion treatment of metal surfaces. The chromium-free aqueous agent is suitable for the treatment of various metal materials, joined in composite structures, amongst others of steel or galvanized steel or the alloys thereof or any combinations of said materials. Furthermore, surfaces of aluminum and alloys thereof can be treated in an anti-corrosive manner using the agent according to the invention. The anti-corrosive treatment is intended in particular as a pretreatment for a subsequent dip-coating. The invention further relates to a metallic substrate that was treated according to a predefined method sequence with the chromium-free agent according to the invention and to the use thereof, particularly in the automotive production of vehicle bodies. | 02-24-2011 |
