Abstract: A water-conserving system equipped to periodically rinse ultra high-efficiency urinal drainage plumbing of corrosive waste liquid and reduce associated gaseous odor is provided. A valve-controllable rinse-cycle supply of water is provided which can selectively be directed into a single drainage conduit which receives waste water from one or more ultra high-efficiency urinals. The system provides embodiments having mechanical valves, or electro-mechanical valves configured responsive to control-signals provided from one or more electronic components, or one or more types of microprocessor-enabled devices, networked devices or computer apparatus.

Abstract: A self-rinsing urinal and very low water-usage mist-dispensing means mountable in close proximity to a normally-interior portion of at least one positionable panel configured slidably or pivotally positionable from an opening of customary cabinetry of a room or a wall. The urinal is positionable from the customary cabinetry or wall opening, between a zero-footprint concealed state and a revealed-for-use state, such that an interior receptacle surface of the urinal is aligned with said very low water-usage mist-dispensing means during at least a revealed-for-use state, to receive from the mist-dispensing means a distributed misted spray aligned with the receptacle, to repel waste-liquid from and facilitate a self-rinsing of the receptacle while employing as little as single-digit ounce(s) of water, per use-cycle. Certain of the embodiments include the option to provide actuating means for positioning and/or aligning one or more urinal-related components in response to receiving a control signal.

Abstract: A wall mountable urinal having an ultra-low use of flush water, minimum material and a self-cleaning action. The urinal comprises an upright bowl that uses a flushing action provided by a misting water jet that is centered above the bowl and that provides a fine mist of water. The water mist washes the entire bowl up to its upper edge and the water droplets that accumulate upon the bowl are guided into a drain. An electrical detector that detects the user's presence is provided that is capable of initiating the flushing water mist during use and for a predetermined time thereafter.

Abstract: A fuel additive controlling and maintaining apparatus used to eliminate the loss of absorbed CO2 gas mixed into liquid hydrocarbon fuel and particularly diesel fuel. In addition to the gas-enriched fuel, a gastight bag is utilized for holding a stabilizing gas mixture of CO2 and air that is not absorbed in the fuel. This bag, which is located within a protective enclosure and is connected into the ullage of a fuel tank, via a conduit, has approximately the same volume as the fuel tank. A two product refueling means is provided so that gas-enriched fuel is delivered to the fuel tank and the CO2 gas is delivered to the gastight bag. During fuel usage, as the fuel tank ullage increases, the gas mixture from the gastight bag maintains the ullage in a substantially filled condition thus, allowing the fuel to remain gas-enriched.

Abstract: Apparatus for facilitating the mixing, absorption and/or retention of carbon dioxide ‘CO2’ in hydrocarbon fuel to economically produce a safety-enhanced and/or improved-combustion fuel. The apparatus includes at least one mixing receptacle having at least one coupling with a controllable inert gas supply; at least one coupling with a controllable hydrocarbon fuel supply; and at least one coupling with a CO2-enriched fuel fuel-line. The mixing receptacle(s) is configured to retain a volume of fuel and a volume of CO2 such that CO2-enriched fuel having a controllable gas-fuel ratio is the product of the mixing receptacle(s) and the gas of the ratio(s) exceeds 0.1 volume of CO2 per volume of fuel and is less than approximately 3 volumes per volume of fuel when conveyed from the receptacle(s). The apparatus controls the exposure of hydrocarbon fuel molecules to an optimal volume of CO2 within the receptacle(s).

Abstract: A safety-enhancing management system for storing, transporting, or transferring hydrocarbon fuel whereby inert gas conveyance provides hydrocarbon fuel receptacles with a combustion suppressing volume of inert gas which displaces potentially combustible fuel vapor/air mixtures which can otherwise collect in the ullages of such receptacles. In one embodiment the inert gas is readily stored, transported, and conveyed in an inert gas-enriched fuel that degasses inert gas from the fuel within one or more receiving receptacles ullage(s). In a second embodiment, a separate controllable supply of inert gas, such as carbon dioxide, is storable in one or more gas receptacle(s), in a gaseous or liquefied state.
