IPC: B27M1/02
Filed: 1995-08-08
Abstract: Wood veneers having enhanced strength and/or stiffness, wood products made therefrom, and methods for manufacturing such veneers and wood products are disclosed. A treated veneer having enhanced strength and stiffness has a population of compacted wood cells extending across at least a portion of the length and width dimensions and into the thickness dimension of the veneer to confer an increased density level, and thus increased strength and/or stiffness levels, to the veneer. Interspersed in the compacted wood cells is a non-saturating loading level of a cured rigid thermoset material which maintains compaction of the compacted cells even after prolonged soaking in water. The preferred loading level is just what is required to maintain compaction of the cells. The preffered thermoset material is polyurea which is formed from a polyisocyanate resin appplied to at least one major surface of the veneer followed by hot-pressing the veneer. The strength and/or stiffness increase, compared to untreated veneer, is about 10 to 150 percent. Treated veneers can be made into various multiple-ply wood products such as laminated veneer lumber and plywood. thereby providing a way to convert relatively weak lumber from fast-grown trees into premium-grade construction material.

Title: A recirculating paint system
Inventor: HOLT EARL R
IPC: F16L37/091
Filed: 1996-07-17
Abstract: A recirculating paint supply system supplies single or multiple paint coating to paint spray stations arranged in parallel or series relation, each station including manually operated flexible monoline and coaxial conduits (102, 104) to supply paint to an improved spray gun (88). In one aspect of the invention, the improved spray gun is comprised of a polymeric material to reduce the overall weight of the spray gun thereby reducing operating fatigue and ailments caused by the use of conventional spray guns. In another aspect, the improved spray gun includes larger air passages (338) which provide for a greater volume of air to pass through the spray gun, thereby providing increased atomization of the liquid coating composition. Thus, the reduced weight, as well as the increased atomization, increases the overall finish quality of the object being painted.

Title: Wrap material with woven fabric
Inventor: TODT GREGORY L
IPC: B32B7/028
Filed: 1996-10-15
Abstract: A method and material for shrink wrapping articles includes wrapping the article with a shrink wrapping material having a shrink/stretch film outer layer and an inner layer of a woven fabric. The shrink/stretch film responds to heat by shrinking around the article being wrapped, while the woven fabric, which does not shrink or shrinks very little, forms pockets which bunch and gather up as shrinking takes place, thereby forming a cushion between the film and the object being wrapped. The woven fabric acts as a reenforcement for the film, both before and after shrinking, thus protecting the article wrapped from a hurled object and other similar hazards, and also protecting the article from direct engagement from the shrink/stretch film, which is relatively abrasive.
