20080299372 | Extra strength polymer composite construction material and process for making the same - A composite material that can be economically produced without the emission of VOCs that is extremely strong and is bonded at the molecular level. An embodiment of the present invention can be a composite of two or more layers with a first layer made from an aliphatic polymer like a polyurea and a resin like an isocyanate resin. A third layer of strengthened urethane foam can optionally be used. The composite material can be made up of layers of material with a first layer of a polyurea polymer and the second layer of an isocyanate resin chemically bonded to the first layer. The first layer can have a glossy outer surface if desired. The second layer can also optionally contain carbon fibers, nano-tubes or basalt fibers for extra strength if desired. The material can be produced in sheets of from 8 to 12 feet wide and from 40 to 60 feet long. Carbon fibers, carbon nano-tubes and Basalt fibers can be added for strength and rigidity. The optional urethane foam layer can contain carbon fibers, carbon nano-tubes or basalt or other fibers for strengthening. | 12-04-2008 |
20090118413 | Composite materials for fuel containment - An enhanced polymer for containing fuel such as in fuel tank construction that uses an one of several commercially available polymers or polymer blends and mixes or blends it with either carbon nano-tubes or carbon nano-fibers and/or with nano-sized smectite clay platelets. The polymer can be further hardened or stiffened by adding or blending or treating with a cross-linking agent. The polymers can be any suitable polymer; however, high density polyethylene, polybutylene terephtalate, polycarbonate or polybutylene terephtalate and polycarbonate blend are preferred. The carbon nano-fibers can have diameters from | 05-07-2009 |
20090199806 | Rigid primer bulb pump - A hand operated primer pump for small marine or other engines generally spark ignition engines used on stern drive boats that prevents transfer of hydrocarbons into the atmosphere. The primer generally mimics and replaces prior art rubber primer bulbs in general shape and possibly color, although it can be made in any shape or color. It generally contains a pump that delivers a precise measured amount of fuel with each stroke of the actuator. The primer can have an ergonomically designed actuator that creates the farthest distance from a fulcrum point for maximum leverage and hence, maximum ease of use. The primer is generally designed with a continuous molded fuel path to seal any source of hydrocarbon leakage as well as being made from materials that prevent transfer of hydrocarbons to the atmosphere. | 08-13-2009 |
20090294453 | Stackable low permeation fuel tank - A marine fuel tank that is stackable due to matching protrusions and recesses on the top and bottom and meets the new low hydrocarbon emission standard. In addition, the tank has side recesses that match straps and a handle that is designed to lift and pour. The tank is generally made from a polymer that has a hydrocarbon permeation of less than 15 g/sq. m/day. | 12-03-2009 |

20110308662 | Marine Fuel Tank Ullage System - A ullage system for a marine fuel tank that maintains an exact ullage space in all marine refueling situations including refueling in moving or pitching and rolling situations. The invention includes two ball valve assemblies that are inserted into a fuel tank at approximately the same level. The two assemblies typically are at opposite ends of the tank. One of the ball valves is smaller than the other in diameter. The smaller valve is coupled to an air vent; the larger valve is coupled to the filler tube. An important feature of the present invention is that it can typically be made to fit any marine fuel tank simply by changing the length of a vent tube to reach the correct ullage level for the tank at hand. The components of the present invention can be made from standard fuel valve materials. | 12-22-2011 |
20150343896 | Fuel Tank Mounted Refueling Device - A refueling device that when mounted to a marine fuel tank facilitates refueling and minimizes the propensity for both spit-back and well back while simultaneously allowing a free flowing open pathway through which vapors generated by the refueling event may pass unencumbered. | 12-03-2015 |
