Patent number: 9920228Abstract: The disclosed composite wood particulate products, adhesives contained in such wood particulate products, and methods of making the adhesive and the wood particulate products employ an aldehyde-free adhesive, and more specifically a formaldehyde-free adhesive. The aldehyde-free adhesive includes an inert additive that extends a resin, such as an isocyanate resin, and forms an evenly dispersed, less expensive polymeric adhesive admixture. The extender-filler of the resin is mixed with water to form a slurry. The slurry can then be mixed with a resin, like the isocyanate resin, to form the adhesive. Various rheology modifiers can be added, if desired, to the extender-filler or the slurry. The adhesive can be blended with wood particles to form a mat that is then pressed into a composite wood particulate product.Type: GrantFiled: March 17, 2017Date of Patent: March 20, 2018Assignee: The Willamette Valley Company LLCInventors: Philip N. Cote, Omar Tiba, Wallace K. Rowland, Robert J. Rubash, Randall C. Zenke, Sudip Chowdhury

Publication number: 20100022687Abstract: A method for producing a lignocellulosic board product is provided. The method comprises providing lignocellulosic material. Furthermore, an adhesive binder system is provided comprising (a) an adhesive binder resin and (b) an extender and/or filler material comprising particularized bran material. The extender and/or filler material does not have an undesirable effect on the chemical and/or the physical properties of the adhesive binder resin to which the extender and/or filler material is added. It also does not impede the performance of the adhesive binder system during subsequent use in producing the lignocellulosic board product. Substantially no flour balling is present in the extender and/or filler material and in the adhesive binder system, respectively. Then, the lignocellulosic material and the adhesive binder system are combined. Finally, the combined lignocellulosic material and adhesive binder system are formed into the lignocellulosic board product.Type: ApplicationFiled: July 22, 2009Publication date: January 28, 2010Applicant: WILLAMETTE VALLEY COMPANYInventors: Wally Rowland, Tim C.

Patent number: 7632557Abstract: This invention provides a method for restoring at least one means defining a railroad spike hole located in a used railroad tie. In this way, the restored railroad tie can be reused in subsequent rail replacement operations. The restored railroad tie is capable of having a railroad spike penetrate and be retained within the confines of the restored railroad spike hole without substantial bending problems. The used railroad tie provided has at least one spike hole located therein. In each the means defining a railroad spike hole is formed a polymeric plug. The polymeric plug comprises a polymeric plug formed of a polymeric material including a plurality of flexible, readily deformable micro-inclusions which allow the formation of spike insertion pathways that track the insertion forces of the railroad spike as it is driven into a material thereby facilitating introduction of the railroad spike into said polymeric plug.Type: GrantFiled: May 17, 2006Date of Patent: December 15, 2009Assignee: Williamette Valley CompanyInventors: Craig B. Stolarczyk, Paul D. Rogers, Philip N. Cote

Patent number: 7399798Abstract: A process is provided for producing lignocellulosic board panels. The process comprises providing lignocellulosic material and an adhesive system. The adhesive system comprises (a) a base adhesive resin and (b) an extender and/or filler material comprising sugar beet material. The adhesive system (i) retains substantial moisture in the lignocellulosic material, and/or (ii) creates a relatively higher initial viscosity, and/or (iii) maintains a substantially stable viscosity thereof over time. The lignocellulosic material is combined with adhesive system. The combined lignocellulosic material and adhesive is then formed into the lignocellulosic board panels.Type: GrantFiled: December 3, 2004Date of Patent: July 15, 2008Assignee: Willamette Valley CompanyInventors: Tim C.
