MULTI-LAYERED STRUCTURE, PRODUCT COMPRISING SAID STRUCTURE AND A METHOD FOR PRODUCING SAID STRUCTURE
Publication number: 20110076439Abstract: The present invention relates to a multi-layered structure (10; 20) comprising a first and a second continuous outer skin (11; 21), and an intermediate layer (12; 22) adhered to the first and second outer skin (11; 21), said intermediate layer (12; 22) comprises substantially spherical elements (13; 23) arranged between the first and the second outer skin (11; 21) The invention is characterised in that the spherical elements (13; 23) at their contact surfaces are bounded to the adjacent spherical element or elements. The present invention furthermore relates to a product comprising the claimed structure and a method for producing said structure.Type: ApplicationFiled: May 29, 2009Publication date: March 31, 2011Inventor: Jacob Zeilon -
Publication number: 20110064907Abstract: Shaped articles made of balsa veneers, balsa chips, balsa strands or balsa strips, which are oriented in the same direction according to their grain direction, and the grain direction of the individual chips deviates by 0° to 30° from the direction of the axis of the grain. The spaces of the adjacent balsa veneers, chips, strands or strips are filled with a, for example foamed, adhesive, the density of which may be the same as or close to the density of the surrounding balsa wood.Type: ApplicationFiled: May 11, 2009Publication date: March 17, 2011Applicant: 3A TECHNOLOGY & MANAGEMENTInventor: Thomas Wolf

Patent number: 7897246Abstract: A man-made, molded article is provided. The article includes a profile including a planar wall, and an adjacent integral molded depression having a contoured wall extending downwardly from the planar wall. The contoured wall includes a bead portion, a cove portion, and a ledge between the bead and cove portions. The articles are stackable, one above another for transport, in a nestable relationship in which multiple contact zones are present between the contoured walls of an adjacently stacked pair of the molded articles. The contact zones include an arcuately extending contact interface zone between the bead exterior and interior surfaces. The depression has a substantially uniform thickness varying by no more than about +1 percent to about ?11 percent in relation to a thickness of the planar wall. Related methods and assemblies are also provided.Type: GrantFiled: April 30, 2008Date of Patent: March 1, 2011Assignee: Masonite CorporationInventor: Steven K Lynch

Publication number: 20110014414Abstract: A simulated commodity tropical hardwood-based panel includes an engineered veneer face including a first wood from one or more sustainable sources of wood. The face has a dyed coloring, a simulated grain, or a dyed coloring and a simulated grain that is substantially similar to the coloring, grain, or coloring and grain of a tropical hardwood veneer. The panel further includes a back and a core disposed between the face and back. The face, the core and back are stacked and adhered together to form a laminated panel. The face of the simulated commodity tropical hardwood-based panel has an appearance that is substantially similar to the appearance of the face veneer of a commodity tropical hardwood-based panel that includes the tropical hardwood veneer. The panel comprises no tropical hardwood from a non-sustainable source of wood.Type: ApplicationFiled: September 24, 2010Publication date: January 20, 2011Applicant: Green Rev LLCInventor: Paul D.

Patent number: 7836655Abstract: The present invention provides a 100% bamboo plank with an interlocking system and associated manufacturing methods. In one embodiment, the 100% bamboo plank comprises first, second, and third layers of 100% bamboo, wherein the layers are laminated together. The layers are independently preconditioned to control moisture content therein. Each layer can be preconditioned by alternately elevating and lowering the moisture content in a plurality of sequential cycles before the layers are laminated together. The middle layer is oriented so its grain is substantially perpendicular to the edges of the plank. The plank had joinery portions formed along the edges, and joinery includes an asymmetric upper joinery member and lower joinery member arrangement for, and at least a portion of the upper joinery member and lower joinery member portions are formed in the second layer.Type: GrantFiled: September 24, 2007Date of Patent: November 23, 2010Assignee: Teragren LLCInventors: Yongjin Chen, David Knight
