This invention provides a noble gas storage and delivery system for ion propulsion using an adsorption bed coupled with a primary storage vessel containing compressed gas or two-phase fluid to control the flow and pressure to a thruster component. The adsorption bed component is lighter weight than conventional flow and pressure control devices, and the system can provide in situ gas cleanup and stable flow from two-phase storage. The use of the adsorption bed allows for independent and isolated operation of multiple thruster components such as refill from the primary storage vessel, throttling, and multiple setpoint flow rates. The pressure and flow is controlled using a flow restrictor and low wattage heat. Flow rates of about 2-50 sccm can be controlled to within about 1.2% or less, and the flow can be throttled by varying the pressure. This noble gas storage and delivery system can be used for earth orbit satellites, and lunar or planetary space missions.

Noble gas storage and flow control system for ion propulsion

A method and system for storing and delivering a noble gas for an ion propulsion system where an adsorbent bearing a noble gas is heated within a storage vessel to desorb the noble gas which is then flowed through a pressure reduction device to a thruster assembly. The pressure and flow is controlled using a flow restrictor and low wattage heater which heats an adsorbent bed containing the noble gas propellant at low pressures. Flow rates of 5-60 sccm can be controlled to within about 0.5% or less and the required input power is generally less than 50 W. This noble gas storage and delivery system and method can be used for earth orbit satellites, and lunar or planetary space missions.

Noble gas storage and delivery system for ion propulsion

Metal powders or granules, comprised of at least 2 alloyed metals selected from the group consisting of alkaline metals, alkali metals, transition metals, metalloids, and rare earth metals are coated with an organic monomer, oligomer, polymer, or other organic compound. The metal powders or granules are in hydride, oxide, or reduced form. The coated metal powders or granules are used to decompose and/or immobilize organic compounds containing at least one hetero atom.

Method for coating reactive metal alloy powders and their use in

Method and compositions for reducing or removing ice formation from surfaces where the compositions consist essentially of (i) one or more polyhydric alcohols and (ii) one or more non-potassium, low carbon percentage organic compounds, and optionally one or more non-potassium, non-halide inorganic compounds and/or monohydric alcohols, whereby the freezing point of the composition is depressed.

Composition and method for de-icing and anti-icing surfaces

A method and system decomposes or immobilizes organic wastes using a metal alloy agent comprised of at least two metals selected from transition metals, alkaline metal and/or and rare earth metals. The method first uses hydrogen and oxygen, with and without mechanical agitation, to decrepitate and activate the metal alloy powders. The organic waste compounds are then introduced to the activated metal alloys. This method of decomposing organic materials effectively destroys organic compounds which contain halogens, sulfur, phosphorous, oxygen, and higher order bonds.

Method and system for the destruction of hetero-atom organics using

A process and system recycles and reuses gray water generated by dishwashers, showers, carwashes, and clothes washers while maintaining the same cleaning performance as current systems. Hollow-fiber membrane ultrafiltration is used to reduce fresh water supply demands and gray water generation where voluminous quantities of the latter are generated. For a clothes washer, the gray water reuse or recycle system consists of a closed-loop water recycle which can be redirected to a storage tank for other applications, or directly used in situ with a clothes washer for subsequent rinse cycles. The process uses, at a minimum, 50% less water than conventional residential and commercial washers, and also decreases detergent requirements by 30% because a portion of the rinse water can be re-used for subsequent wash cycles.

Process and system for recycling and reusing gray water

A process and apparatus for treating and detoxifying salts-hydroxides scrubber wastes containing nitrite salts or sulfite salts so that the final product has low nitrite or sulfite content, a neutral pH and is usable either as a base blend or as a stand-alone liquid product for agricultural applications. One approach is to have a continuous flow oxidation of the waste solution by ozone followed by a neutralization step with MKP. Another approach is to perform oxidation and neutralization in one step by the addition of hydrogen peroxide and MKP.
