Title: Method for determining warp potential in wood
Inventor: STANISH MARK A
IPC: G06F9/46
Filed: 1999-09-01
Granted: 2006-06-13
Abstract: A method for determining warp potential of wood. One embodiment comprises nondestructively obtaining lengthwise shrinkage rates and grain angles of wood - such as trees, logs, or lumber - then determining warp potential of the wood based on the lengthwise shrinkage rates and grain angles. The method typically comprises measuring plural lengthwise shrinkage rates and plural grain angles to determine wasp potential. Where the wood comprises lumber, lengthwise shrinkage rate and grain angle measurements typically are made on at least one major planar surface of the lumber at at least two measuring points separated by a predetermined distance, such as at substantially one-foot intervals along the lumber. Particular embodiments of the present invention determine lengthwise shrinkage rates using electromagnetic energy, acoustic energy, and combinations thereof. Working embodiments of the method use ultrasound energy to determine lengthwise shrinkage rates and grain angles. Another embodiment of the present invention comprises providing a piece of wood having at least one major planar surface, positioning the piece of wood adjacent to a device for imparting energy through the piece of wood to determine at least one lengthwise shrinkage rate and at least one grain angle. Embodiments of the present invention are automated and can be adapted to industrial processes for commercial production of lumber o r for forest management practices. Warp potential can be determined using a finite element model (FEM).

Title: Solution polymerization process catalyzed by a phosphinimine catalyst
Inventor: DOBBIN CHRISTOPHER JOHN BROOKE
IPC: C08F110/02
Filed: 2001-05-11
Granted: 2009-09-08
Abstract: A solution polymerization process using a phosphinimine catalyst and a boron activator is conducted at a temperature of about 170°C or greater in the presence of trialkyl aluminum to produce polyethylene having a comparatively broad molecular weight distribution. The polyethylene product produced by the process of this invention is desirable because it can provide enhanced "processability" in comparison to polyethylene having a narrow molecular weight distribution. The process of this invention is advantageous in comparison to prior art processes for the preparation of "broad" polyethylene which use two polymerization reactors and/or more than one polymerization catalyst. The polymers produced by the process of this invention are potentially suitable for the preparation of plastic film. For example, a polyethylene according to this invention and having a density of about 0.93 grams per cubic centimeter and a melt index I2 (according to ASTM D 1238) of about 2 may be advantageously used to prepare cast film. In addition the present polyethylenes may be used for the manufacture of a wide variety of other goods including blow molded parts (such as tanks, drums and containers for gasoline or other liquids); extruded goods (such as profiles or hoses); and injection molded goods such as food containers.
