Publication number: 20090144029Abstract: Aspects of the present invention are directed at determining whether a structure's braced wall layout complies with building code bracing requirements. In accordance with one embodiment, a method is provided that obtains input describing the geometry of the braced wall line. Then, the applicable building codes that define the wall bracing requirements for the structure are identified. Each bracing member in the braced wall line is selected and processed so that the method may compile data that identifies the location of each bracing member and quantifies the bracing provided in the aggregate. Then, a determination may be made regarding whether the aggregate amount and location of bracing that is provided is a sufficient to satisfy the applicable building codes.Type: ApplicationFiled: November 30, 2007Publication date: June 4, 2009Applicant: Weyerhaeuser Co.Inventors: Christopher W.

Patent number: 7530197Abstract: A method and system for automatically harvesting and screening plant embryos in multiple stages to identify those embryos that are suited for incorporation into manufactured seeds are provided. The method includes generally three steps. First, plant embryos are automatically sorted according to their rough size/shape and also singulated into discrete embryo units, for example by vibrational sieving. Second, the sorted and singulated plant embryos are classified using a first classification method. For example, each embryo may be imaged by a camera and the image is used to ascertain the embryo's more precise size/shape. Third, for those embryos that have passed the first classification method, a second classification method is applied. For example, a pre-developed classification algorithm to classify embryos according to their putative germination vigor may be applied to the same image used in the first classification method, to identify those embryos that are likely to germinate.Type: GrantFiled: May 24, 2004Date of Patent: May 12, 2009Assignee: Weyerhaeuser Co.Inventors: Roger Timmis, Edwin Hirahara, Harry G.

Publication number: 20090084833Abstract: The embodiments of the present invention provide a blank of foldable material that is configurable to form a container. When formed, the container includes air cell structures that allow for the container with a constant outside volume to have a variable inside volume. The air cell structure of this container functions to prevent telescoping of vertically stacked containers for strength and stability. The relative size of the panels used in forming the air cell portion from one container to the next is variable to allow for a single outside volume, but differing inside volumes.Type: ApplicationFiled: September 28, 2007Publication date: April 2, 2009Applicant: Weyerhaeuser Co.Inventors: Walter D. Keefe, JR., Richard G. Wachter

Publication number: 20090084056Abstract: A shear brace assembly is provided which laterally braces wall lines within a structure, such as a house or other residential construction, while also providing vertical and out-of-plane load carrying capacity. The assembly consists of one or more wood-based panel(s) which are rigidly connected to concrete, masonry or wood support material directly below or above the shear brace assembly bearing surface. The term “wood-based” should be interpreted to mean that the panel may be constructed from a natural wood, or partially or wholly from an engineered wood, such as Timberstrand®, Parallam®, or the like. Ductile anchorage assemblies are used below, and in some applications, above the individual panels.Type: ApplicationFiled: September 27, 2007Publication date: April 2, 2009Applicant: Weyerhaeuser Co.Inventor: Thad Scott Robertson

Publication number: 20090084834Abstract: A container is provided that is generally rectangular in shape, thereby forming side walls, end walls, a top, and a bottom. The container includes a pocket located on the interior of one of the walls adjacent the bottom. The container further includes an access flap formed in the wall corresponding to the pocket. The access flap acts like a door for selectively providing access to the pocket from the exterior of the container.Type: ApplicationFiled: September 27, 2007Publication date: April 2, 2009Applicant: Weyerhaeuser Co.Inventor: Alan J.

Publication number: 20090082903Abstract: Provided is a system for cutting and sorting of engineered wood products. Using appropriate software, a designer may model an entire house's structural frame. The dimensions and labeling for individual members of the structure are extracted from the model and captured by the software. The software may batch and optimize the products to be cut on the saw and develop sawing control instructions. The instructions are used by the saw to process the parts according to the house structure design. As the parts are processed by the saw, they are discharged and sent to an outfeed system that will stack the engineered wood products according to the parameters defined by the workstation operator. The system can handle the multiple lengths and widths of engineered wood parts from the saw and stack them in the order the software may specify.Type: ApplicationFiled: September 24, 2007Publication date: March 26, 2009Applicant: Weyerhaeuser Co.Inventor: George H. Sander

Publication number: 20090001629Abstract: A process and material therefrom is described where a material comprised of a continuous orientable polymer matrix with one or more discontinuous or continuous second phases is stretched in the solid state using more than one device to apply force to the unoriented material to form a material that consists of a continuous oriented polymer matrix with one or more other phases. At least one of the phases releases from the oriented polymer matrix forming voids during the orientation process, thereby reducing the density to less than that of the original unoriented mixture. One or more of the phases may stay bonded to the continuous oriented polymer phase, acting as a reinforcing agent and forming no voids. Methods for forming such a material allowing for the control of the final shape and affecting the final density independent of the composition are also disclosed.Type: ApplicationFiled: June 29, 2007Publication date: January 1, 2009Applicant: Weyerhaeuser Co.Inventors: William R.
