| 20090280346 | METHOD FOR IMPREGNATION OF WOOD COMPONENT WITH SOLID PARAFFIN WAX, APPARATUS THEREFOR AND WOOD COMPONENT SO IMPREGNATED - A method for treating a piece of wood impregnates the piece of wood with a water repellent, wherein the water repellent is solid at ambient temperatures. The method includes the steps of providing a piece of wood to be treated; heating the piece of wood for a predetermined period of time, the piece of wood being heated at a temperature A; subsequently immersing at least a portion of the piece of wood in a bath of liquefied water repellent, the bath being at a temperature B, for a predetermined period of time. Thereafter the piece of wood is removed from the bath and allowed to cool. The temperature A is above 100° C. and the temperature B is below 100° C. but above a liquefying point for the water repellent, and a differential between temperatures A and B is at least 60° C. | 11-12-2009 |
| 20090102232 | HARDWOOD TRUCK FLOORING WITH WOOD PRESERVATIVES - A hardwood floor used for making trailers in the transportation industry is treated, at least for a portion thereof, with a water-based wood preservative. The preservative is preferably a borate-based preservative. When the floor is provided with a steel plate at a rear thereof, the wood preservative located in the vicinity of the steel plate prevents the formation of fungi and increases the useful life of the floor. | 04-23-2009 |
| 20080236704 | UTILIZATION OF COLORATION TO IMPROVE THE DETECTION OF "HIT OR MISS" DEFECTS WHEN USING SCANNER EQUIPMENT AND AN AUTOMATED SAW TO REMOVE DEFECTS IN WOOD PIECES - In a wood processing plant, planks are typically split into strips and then passed through an automated cross-cutting saw station to remove defects such as knots, cracks or flash. One defect which also occurs is the hit and miss defect caused by a planer and/or a sander. In order to improve the performance of the cross-cutting saw station, color is applied to the wood prior to being planed and sanded. The cross-cutting saw station is then modified to optically inspect the wood for the presence of color, indicating a hit and miss defect, and to remove the portions of the wood containing color. | 10-02-2008 |
