  • Publication number: 20230194165
    Abstract: Wood kilns, electrode systems for wood kilns, and methods of using the systems for the radiofrequency (RF) drying and phytosanitizing of wood are provided. The electrode systems are based on a three-electrode design in which a central plate electrode having winged edges is disposed between a pair of ground plate electrodes. The winged edges of the central electrode improve the uniformity of heating during the phytosanitizing process, relative to a five-electrode parallel plate system, or a three-electrode parallel plate system having a conventional planar central plate electrode.

  • Publication number: 20220288809
    Abstract: A method for treating wood packaging materials using Radio Frequency heating includes the steps of heating wood packaging materials using RF heating and applying a pressure before the heating or incrementally applying a pressure during the heating. The wood packaging materials are heated in a RF operating unit that has a sealed chamber with an inner surface and a liner cover a majority of the inner surface, the liner having a heat-reflective inner face and an insulation layer between the inner face and the inner surface.

  • Patent number: 10898599
    Abstract: A method for treating wood packaging materials using Radio Frequency heating includes the steps of heating wood packaging materials using RF heating and applying a pressure before the heating or incrementally applying a pressure during the heating until a temperature of the wood packaging materials reaches at least 60° C. and that temperature is maintained for at least 1 minute.

  • Publication number: 20040074183
    Abstract: A wood deck connection system and a method for the installation of wooden deck panels using the system is disclosed. The reliable shear withdrawal connection system comprises a headed connector mechanically fastened to a steel, concrete or wooden girder, a wood-based deck panel having a receiver hole bored therein, and a grout agent deposited throughout the receiver hole. The deck connection system enables top-side installation of deck panels and provides improved shear strength, withdrawal resistance, reliability and fatigue behavior of the wooden deck system.
