Publication number: 20080243424Abstract: Methods are provided for predicting warp of a lumber product at a given condition, such as relative humidity, temperature, moisture content, or the like. Note that this methodology may apply to any of crook, bow, twist, cup, or combinations of these quantities. The method involves measuring an original warp of a first wood product at a known condition; changing the condition of the first wood product to a new condition; measuring a second warp of the first wood product at the new condition; developing a prediction model based on data from the original warp and condition and the second warp; measuring an original warp and condition of the given wood product; and inputting data from the original warp and condition of the given wood product to the prediction model to determine warp at a given condition.Type: ApplicationFiled: March 27, 2007Publication date: October 2, 2008Applicant: Weyerhaeuser Co.Inventors: John E.

Publication number: 20080220562Abstract: A low channel length organic field-effect transistor can be produced in high volume and at low cost. The transistor structure includes successively deposited patterned layers of a first conductor layer acting as a source terminal, a first dielectric layer, a second conductor layer acting as a drain terminal, a semiconductor layer, a second dielectric layer, and a third conductor layer acting as the gate terminal. In this structure, the transistor is formed on the edge of the first dielectric between the first conductor layer and the second conductor layer. The second conductor layer is deposited on the raised surfaces formed by the dielectric such that conductive ink does not flow into the trough between the dielectric raised surfaces. This is accomplished by coating a flat or rotary print plate with the conductive ink, and applying the appropriate pressure to deposit the materials only on the raised surfaces of the dielectric. The second metal is automatically aligned to the layer beneath it.Type: ApplicationFiled: May 20, 2008Publication date: September 11, 2008Applicant: Weyerhaeuser CompanyInventors: Klaus Dimmler, Robert R.

Publication number: 20080216981Abstract: System for conveying, mixing, leveling, and flaking dewatered pulp to produce pulp flakes suitable to be used in a dryer. The system produces a consistent flow rate of pulp and uniform pulp flakes in terms of pulp flake size and pulp flake moisture content. The system includes a rotating shaftless screw conveyor for mixing and conveying dewatered pulp. The system includes a belt conveyor. The pulp is deposited from the screw conveyor onto the moving belt conveyor through a chute. The system includes a rotary doctor. The pulp is leveled with the rotary doctor located above the belt conveyor to produce a substantially even rate of mass flow of pulp along a length of belt conveyor. Uniform and consistent quantities of pulp per unit time can then be fed from the belt conveyor to a pulp flaker that then translates into an even rate of pulp mass flow to the dryer.Type: ApplicationFiled: May 19, 2008Publication date: September 11, 2008Applicant: Weyerhaeuser Co.Inventors: Ramon C.
