Abstract: Adhesive/adherend systems {10) of this invention comprise a siloxane-modified adhesive component (14) and a siloxane-modified adherend component (12, 16). The siloxane-modified adhesive component (14) is prepared by combining an epoxy resin with an organosilane ingredient, a polysiloxane resin, an amine hardener, an organometallic catalyst, a base catalyst, and any thickener and extender pigment. The siloxane-modified adherend component (12, 16) is prepared using a polysiloxane resin and may also contain other resins suc as epoxy, phenolic, polyester, vinyl ester, polyurethane, polyamide, melamine, furan, acrylate, thermoplastic polyvinyl chloride, polyethylene, polycarbonate, ABS, polystyrene, ethylene vinyl acetate, polyvinyl acetate, polyamide, and polypropylene resins. When placed into contact with one another, the siloxane groups in the siloxane-modified adhesive (14) and siloxane-modified adherend components (12, 16) form Si-O-Si bonds between themselves to form an attachment force that both occurs at ambient temperature within a reasonable amount of time, and that is greater than otherwise possible using adhesive/adherend systems having unmodified adhesive and/or adherend components.

Abstract: A safety or traffic marker is capable of providing a continuous physical border between two locations.  A housing, or one of several adapters, are employed in a conventional traffic cone to dispense an elongated strip of tape therefrom.  In one embodiment, the housing is physically incorporated into the interior of the marker, and is adapted for easy insertion and removal of a tape or safety material dispenser.  In order to achieve easy insertion of the tape dispenser into the housing, the upper portion of the marker is split into separable sections.  Since the marker is fabricated from a deformable material, the upper portion can be manually separated into an opened position for insertion of the tape dispenser therein.          Hook and loop fasteners may be used to fasten together the two sections into a closed position.  Adapters may also be used in conjunction with conventional traffic markers for creating a continuous physical border between two or more locations.

Abstract: Plant sterols have been shown to be cholesterol-reducing agents in human serum. In the present invention, plant sterols, plant stanols, plant sterol esters and other non-toxic sterols are micromilled with emulsifiers in a solvent (water or edible oil) to produce dispersion which can be incorporated into full-fat, reduced-fat, low-fat, fat-free and triglyceride- free food products. Such water-based or edible oil-based dispersions can be used to incorporate relatively high levels of such sterols/stanols in food products without the adverse organoleptic effect normally associated with the use of such plant sterols and plant stanols.
