Patent CA-2448461-A1 (CA)
Inventor: WILLIS CHARLES C
IPC: A43B23/02
Filed: 2003-11-06
Abstract: A slip-on footwear system including an upper that defines an elasticized gore in the heel portion of the footwear. In the heel portion of the footwear, one or more upper panels cooperate to define a recess, also referred to as a gore, which is bounded by a perimeter. An elastic panel is secured along the perimeter and cooperates with the one or more upper panels to further define an opening through which a foot is inserted into the upper. The elastic panel is stretchable and resilient so that when a user inserts their foot into the footwear, the gore opens-up, which in turn enlarges the opening. A heel flap may be secured to the upper panels in the heel region below the gore to conceal the gore and elastic panel, without inhibiting the stretch of the elastic panel. The heel flap may also add structural rigidity to the footwear.

Title: Method and system for the treatment of betula wood
Inventor: HUARD MICHEL
IPC: B27K5/00
Filed: 2004-04-07
Abstract: A method and a system for treating betula wood to change the coloration thereof to resemble that of Cherry wood or heartwood of birch is described. The betula wood is introduced in treatment chamber which is under atmospheric pressure. Hot steam from a steam generator is introduced in the treatment chamber in a lower section thereof for subjecting the betula wood to be treated to a hot water vapor environment. The temperature and humidity levels in the treatment chamber are controlled over a time span until the betula wood is completely saturated with water and has obtained a desired color transformation. This color transformation is uniform throughout the thickness of the wood and thereby hi-lights the grain in the betula wood while at the same time changes its color whereby it resembles Cherry wood or heartwood of birch. The treated wood is then cooled in the treatment chamber and removed therefrom for further processing.
