  • Patent number: 11319025
    Abstract: A marine vessel hull, and marine vessels comprising at least one such hull, comprising a non-entrapment hull having at least one partial-beam, longitudinally vented transverse step, each partial-beam, longitudinally vented transverse step comprising a transverse step with port and starboard portions that do not continuously extend from port chine to starboard chine. In one embodiment, the port and starboard portions extend inwardly to an intersection with at least one longitudinal step but do not fully extend from starboard to port across the full beam of the vessel. In another, the port and starboard portions extend between longitudinal steps across the centerline but not to the starboard and port chines.

  • Patent number: 10858069
    Abstract: A marine vessel hull, and marine vessels comprising at least one such hull, comprising a non-entrapment hull having at least one longitudinally vented transverse step, each longitudinally vented transverse step comprising a transverse step, and one or more longitudinal steps extending forward therefrom. Each longitudinal step portion has a cross-sectional profile defining a cutout into the hull relative to a line defined by a deadrise angle of the hull. The cutout defines a vertical rise starting from the line defined by the deadrise angle and a run tilted outwardly upward at a non-horizontal angle less than the deadrise angle and that extends to an intersection with the line defined by the deadrise angle.

  • Patent number: 10246162
    Abstract: A marine vessel hull, and marine vessels comprising at least one such hull, comprising a non-entrapment hull having at least one longitudinally vented transverse step, each longitudinally vented transverse step comprising a transverse step extending from starboard to port, and one or more longitudinal steps extending forward therefrom. One or more longitudinal steps may also extend aft of an aft-most longitudinally vented transverse step, and may converge to a relatively lesser depth at the stern than a maximum depth at a location fore of the stern. The one or more longitudinal steps may gradually transition to a maximum depth aft of a discontinuity introduced by a forward transverse step. The hull may also have one or more longitudinal step tunnels.

  • Patent number: 9873844
    Abstract: A hydrocarbon composition that is produced through a solvent extraction of woody tree material is provided. The composition is suitable for use as a petroleum substitute. The woody tree material is sourced from hydrocarbon-bearing trees or shrubs containing relatively low molecular weight hydrocarbons. Suitable tree species include pine and eucalyptus trees. A raw woody tree biomass is processed into solvent-permeable particles and chips. Naturally occurring hydrocarbons found in the wood particles are extracted using an organic solvent extraction process. The organic solvent utilized is a mixture of organic solvents that includes a non-polar solvent and a polar solvent. The extracted hydrocarbons are separated from the solvent mixture and may be used as a petroleum substitute, while the solvent may be reused in the extraction operation.

  • Patent number: 9139789
    Abstract: A method for producing a petroleum substitute through a solvent extraction of woody tree material is provided. A raw biomass of woody tree material is processed into solvent-permeable wood particles and chips. Naturally occurring hydrocarbons suitable for use as a petroleum substitute are extracted by a mixture of polar and non-polar organic solvents in a counterflow operation. The extracted hydrocarbon oils are then separated from the solvent for use as a petroleum substitute, while the solvent is reused in the extraction process.

  • Publication number: 20150065763
    Abstract: A preferred embodiment of the present invention is directed generally to a composition of matter and, more specifically, to a composition comprising a petroleum substitute produced from renewable, woody tree-based sources through a solvent extraction process. The woody tree sources are typically hydrocarbon-bearing trees or shrubs capable of producing significant quantities of liquid terpenes such that the process of extracting hydrocarbons from the woody tree material is economically viable. In a preferred embodiment of the invention, the woody tree material is derived from pine or eucalyptus trees, or a combination thereof. These tree species contain relatively large quantities of relatively low molecular weight hydrocarbons. A raw woody tree biomass is processed into a plurality of solvent-permeable wood particles. Naturally occurring hydrocarbons found in the wood particles are then extracted using an organic solvent extraction process.

  • Publication number: 20150020441
    Abstract: A preferred embodiment of the present invention is directed generally to a composition of matter and, more specifically, to a composition comprising a petroleum substitute produced from renewable, herbaceous plant-based sources through a solvent extraction process. The plant sources are typically hydrocarbon-bearing plants capable of producing significant quantities of liquid terpenes such that the process of extracting hydrocarbons from the plant material is economically viable. In a preferred embodiment of the invention, the plant species is Euphorbia tirucalli, a species that contains relatively large quantities of relatively low molecular weight hydrocarbons. A raw plant biomass is milled and formed into a batt of plant material having generally uniform properties. Naturally occurring hydrocarbons found in the plant material are then extracted using an organic solvent extraction process.

  • Publication number: 20120197052
    Abstract: A composition of matter with of the creation of low molecular weight hydrocarbon fluid called Phytoleum from Euphorbia tirucalli biomass and a process for the extraction and refinement in making the same composition through the creation of a batting mat and multi-phase solvent extraction. A preferred embodiment includes the steps of manufacturing a fibrous batting mat from the raw biomass, crushing the biomass, shearing the biomass with a rotating knives blade array, compressing the biomass by passing the biomass through press rollers, amalgonating the biomass into a Batting Mat, subjecting the Batting Mat to a phased multi-wash solvent system, extracting the solvents and oils liquid solution for recovery, subjecting the liquid solution to a centrifugation system to extract the Phytoleum hydrocarbon oil from the other components, and refining the final product to yield Phytoleum which is a composition of matter including Tirucallene A and Tirucallene B and other oligomerized pentenes.
