| 20090120846 | Shale shakers with cartridge screen assemblies - A screening apparatus for separating components of a material by vibratory separation which, in certain aspects, includes a vibratable box connected via vibration isolators within a container, the box including screening apparatus thereon or the vibratory separator having replaceable screening cartridges within a container. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b). | 05-14-2009 |
| 20090242466 | Automatic Vibratory Separator - Methods for automatically controlling a vibratory separator, e.g., but not limited to a shale shaker for processing drilling fluid, the methods in certain aspects including: introducing material to a vibratory separator; sensing with sensor apparatus a state parameter indicative of operation of the vibratory separator; providing a signal indicative of a value of said state parameter to control apparatus; and, with the control apparatus, automatically controlling the vibratory separator based on the level of the state parameter. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 CFR 1.72(b). | 10-01-2009 |
| 20100038143 | Drill cuttings treatment systems - A thermal treatment system for receiving liquid from drill cuttings material in which a metering screw system feeds material to a vessel of a thermal reactor. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b). | 02-18-2010 |
| 20100089652 | Shale Shakers with Selective Series/Parallel Flow Path Conversion - Methods and systems are disclosed employing a shale shaker for processing a mixture of drilling fluid and solids with multiple screen assemblies and conversion apparatus for switching flow to the screen assemblies between series flow and parallel flow; and in one aspect, a screen or screens for screening lost circulation material. | 04-15-2010 |
| 20100270216 | SHALE SHAKER - A shale shaker for separating solids from solids laden drilling fluid is disclosed as having a basket with a scalping screen deck, at least one first screen deck and at least one second screen deck. The basket further may have a flow tray arranged between said scalping screen deck and at least one first screen deck, and a plurality of first ducts and a plurality of second ducts, the plurality of first ducts for directing solids laden drilling fluid to the at least one first screen deck. The second plurality of second ducts are for directing solids laden drilling fluid to said second screen deck. | 10-28-2010 |
| 20110210083 | APPARATUS AND METHOD FOR SEPARATING SOLIDS FROM A SOLIDS LADEN DRILLING FLUID - A method for operating a shale shaker to separate solids from a solids laden fluid, the shale shaker comprising a basket for holding at least one screen and a vibratory mechanism for vibrating the basket to an acceleration value, the method comprising the steps of monitoring the magnitude of the load of solids laden fluid in the basket and adjusting the acceleration value induced in the basket according to the magnitude of the load, wherein the acceleration is stepped down to a low acceleration value below a low load threshold. | 09-01-2011 |
