Title: Conversion of drilling waste
Inventor: MALHIS SOUHEIL
IPC: C10G73/23
Filed: 2002-05-13
Granted: 2009-12-08
Abstract: Drilling waste resulting from drilling processes of oil and gas wells using hydrocarbons based drilling fluids contains not only hydrocarbons but also the separated cuttings, and other organic and inorganic additives. This kind of waste contains a considerable amount of hydrocarbons and is classified as a hazardous waste. The present invention claims a method for remediation of said drilling waste, where the drilling waste is converted to a solid fuel that is environmentally friendly for storage, transportation and incineration. The said solid fuel presents no longer clanger to the surrounding aria and groundwater and has an economical energy value. Using several treatment stages, the residual emulsifiers in the drilling waste are chemically in an acidic milieu destabilized and the soil is turned accessible to the hydrocarbons. By using a polyelectrolyte in aqueous slurry the hydrocarbon molecules are coagulated and, under normal conditions, irreversibly homogenously adsorbed on the soil particles. Finally Separation and Dewatering of the said solid fuel can be easily accomplished. The process secures immobilization of the hydrocarbons and no loss in BTU value of the original drilling waste. The BTU value of the converted fuel can be increased by separation of large particulates from the aqueous slurry before immobilization the hydrocarbons. After rinsing the separated particulates with water they become free of hycdrocarbons and can be left onsite.

Title: Method of evaluating logs to predict warp propensity of lumber sawn from the logs
Inventor: FLOYD STANLEY L
IPC: G01N3/00
Filed: 2002-10-07
Granted: 2009-12-22
Abstract: A method of predicting warp of lumber that might be sawn from any given log is disclosed. The method involves measurement of stress wave velocity in the tree stem, either as a standing tree or felled log. A scan is then made to define the exterior geometric configuration of the log. In particular, measurements relating to lack of longitudinal axis linearity (sweep) or irregularity of cross sections of the log are important. Stress wave values and selected geometric parameters are entered into a multivariate regression equation to predict warp propensity of lumber that might be sawn from the log. Separate equations are required for each species for prediction of crook and bow. The equations are originally derived by examination of a representa-tive population of logs of the particular species and locale and measurement of warp in lumber sawn from the logs. The stress wave information may be combined with the geometric characteristics in the computer associated with a log scanner at the green end of a sawmill. Logs determined to produce warp prone lumber can be iso-lated and used to produce other products such as timbers or plywood where warp is not as critical.

Abstract: The flush mount breakaway post coupler is a coupler for connecting a post to a ground anchor. The coupler has an upper section and a lower section. The upper section has a socket for receiving a post, a shear section, and an anchor attachment portion for attachment to the lower section. The shear section is hollow and cylindrical and has a groove defined about its exterior so that the wall of the shear section is thin, fracture of the coupler occurring around the annular groove. The lower section is an expansion anchor having a threaded bore for receiving a bolt, the lower section being placed in a tubular ground anchor, or a hole defined in the ground. The socket has a bottom wall, and a cylindrical bore extends through the shear section to a predetermined base in the anchor attachment portion. A bolt hole extends from the base of the bore through the anchor attachment section. A bolt connects the upper and lower sections so that the coupler is wedged into the tubular ground anchor as the bolt is tightened. The coupler is installed with the shear section coplanar with ground level. When the coupler fractures, the socket breaks off, leaving no portion of the coupler above ground, and the remaining annular edge of the shear section and the top surface of the bolt head level with the surface of the ground.
