Abstract: A garment having a sleeve, the sleeve including a cuff movable between a retracted position in which an end of the retracted cuff rests proximate the wrist of the user, and an extended position in which the end of the cuff extends over at least part of the hand of the user, the cuff including an attachment region for attaching a protective device thereto. The attachment region of the cuff is exposed when the cuff is in the extended position and allows a protective device, such as a puck, to be releasably attached to the cuff. The protective device facilitates sliding during skateboarding by placing the protective device into contact with the ground, the protective device slides over the ground while providing protection to the hand of the user. The cuff may be secured in place with a loop in the cuff that can be tightened.

Abstract: A method of producing a film having a diffractive surface pattern in selected areas by processing a precursor film having a diffractive surface relief throughout one or more zones together defining a target area of the precursor film; the method comprising applying material to a selected zone of the diffractive surface relief so as to nullify the diffractive effect of the surface relief in the zone.

Abstract: The present invention relates to a process for treating wood and other cellulosic materials to render the resistance to wood attacking organisms, such as termite, fungi and insects. More particularly, the present invention relates to a process for treating wood with borate preservatives which contain at least one boron-containing component and at least one organic component capable of retaining impregnated borate inside the treated wood even upon contact with water. The organic borate-retaining components are lignin-based materials, alcohol-based materials, protein, and wood extracts.
