An LED coupled to a large core plastic optical fiber light guide with a tubular connector having a first bore into which the light guide is inserted, a second bore into which the LED and its attached wires are inserted and a third bore adjacent to the first bore, extending between the first and second bores and into which the LED is positioned so that when illuminated the LED transmits light into the guide with the first bore. The connector includes helical threads formed in the first bore into which the guide is threaded to securely retain the guide within the first bore and which form a seal to prevent contaminants from entering the region in the first bore adjacent the LED. Alternatively, the connector includes one or more internal channels extruding around the inner periphery of the bore and into which one or more O-rings are positioned so that the guide is securely retained within the first bore and that a barrier is formed to prevent contaminants from entering the region in the first bore adjacent the LED. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of the claims.

A towing hitch extension is provided that is adapted to protect the rear bumper, especially a plastic bumper, of a towing vehicle. The hitch extension includes a tow bar with front ends and rear ends. The front end couples to the rear towing hitch of the towing vehicle. The rear end is mounted to a transversely extending, horizontally oriented, enlongated cross bar medially an also to a trailer hitch receiver hitch receiver that is somewhat above the tow bar. A pair of guard projections, such a pair of tow hooks for example, upstand from the cross bar on either side of the tow bar. Braces, preferably metal plate members, are preferably mounted to the tow bar and the cross bar to strengthen the position of the cross-bar relative to the tow bar.

An improved fuel tank and method of forming a fuel tank utilize reinforced porous metal composite materials. In one embodiment, the composite material includes a fully dense, fluid-impermeable skin combined with a porous metal baffle. The skin and baffle may be formed as a single monolithic system via electrodeposition of a nanolaminate material into at least a portion of open, accessible void space within a porous preform (e.g., a metal foam preform) and on the exterior surface of the preform to form the fluid-impermeable skin.

A insulated masonry wall system having insulation blocks between structural and face blocks to provide structures that are strong, inexpensive, avoid thermal bridges, and resist transmission of heat. The walls are attractive and versatile, and an enormous variety of decorative face members may be utilized. The face blocks are attached to the structural blocks to prevent facing materials from falling even if fire destroys the insulation blocks between the structural blocks and the facing. The system resists water penetration and effectively drains water that does penetrate any portion of the system.

The present invention involves a roofing assembly of a plurality of structural components arranged unattached as a frame in a mold. The frame is sprayed with foam and the structural components are encapsulated within the foam.

The invention relates to the inhibition of crystallization in rosin and rosin-based materials through the use of crystallization inhibitors. More specifically, the crystallization inhibitor is selected from the group consisting of carboxylic acids and the salts of carboxylic acids. The invention also relates to the process of inhibiting crystallization in rosin and rosin-based materials.

The wall are filled with an energy absorbing material. The lower ends of the vertical studs are connected to a lower track.

Fibrous sheets are coated or impregnated with a biodegradable composition to render the sheets more resistant to penetration by liquids. Biodegradable polymer blends suitable for use in coating or impregnating a fibrous sheet can be manufactured from at least one type of polyhydroxybutyrate, optionally in combination with at least one additional biodegradable polymer (e.g., a “hard” biodegradable polymer having a glass transition temperature of at least about 10° C. and / or a “soft” biodegradable polymer having a glass transition temperature less than about 0° C. Sufficient inorganic filler may be included so as to render the treated sheet microwaveable. The biodegradable polymer compositions are especially well-suited for coating or impregnating paper sheets, e.g., 12-15 lb / 3000 ft2 tissue paper to yield food wraps. Food wraps will typically be manufactured to have good “dead-fold” properties so as to remain in a wrapped position and not spring back to an “unwrapped” form.

A dispenser is provided for viscous condiments. The dispenser includes a tubular sidewall having opposite ends. One opposite end is open and can receive a plunger or piston therein for applying force to condiment contained within a compartment inside of the sidewall. The other end of the sidewall includes a dispenser valve assembly comprising a member secured to an inturned flange portion of the sidewall with the flange portion being generally normal to the sidewall. The dispenser valve assembly is suitably secured to the flange portion as by heat sealing to form a composite laminated structure that is resistant to the penetration of liquids from the condiments. A bead of hot melt can be provided to seal an exposed outer edge of the dispenser valve assembly and to seal the dispenser valve assembly to the sidewall. The dispenser valve assembly includes a valve plate having one or more selectively openable discharge openings formed therein that will open and close under the influence of pressure applied to the condiment within the dispenser.

A canine protective suit comprising a face mask, a upper body protector and a lower body protector, wherein the face mask is removably secured to the upper body protector, and wherein the lower body protector is removably secured to the upper body protector. The upper body protector comprises elastic bands, wherein the elastic bands secure at least two front leg panels. Similarly, the lower body protector comprises elastic bands, wherein the elastic bands secure at least two back leg panels. To use, a canine's two front legs are placed into the two front leg panels as the upper body protector is placed on the canine. Similarly, the canine's rear legs are inserted into the back leg panels as the lower body protector is installed on the canine. The face mask is then disposed on the canine's face and secured to the upper body protector.
