A gas generating process, which is for the continuous production of energy and hydrogen for rocket and other propulsion and is also for the continuous production of hydrogen, utilizes the reaction of metallic materials, particularly aluminum, with organic materials, particularly hydrocarbons provided as jet fuel, and with water or an oxidizer which is predominantly water. In comparison with related reactions, the reaction produces hot gases containing more hydrogen and the products have a lower temperature for the same specific impulse. The process incorporates organic liquids with metallic powders to produce desirable, lower molecular weight exhaust gas products; and the increased hydrogen is desirable for use with a fuel cell and in connection with propulsion of a super-cavitating underwater device. The process is advantageous in that a metal, in powdered form, and a hydrocarbon liquid may be provided together as a slurry or gel for effective metering. The metallic material may also be provided with the organic material in the form of a binder as used in solid propellants, and the organic material and water may be provided together in the form of a water containing liquid monopropellant. The hydrogen containing product gases from the reaction may be further reacted with suitable oxidizers for production of additional energy or steam. The reaction is particularly useful for underwater vehicles where ambient water is available and the reaction products may be used for propulsion.

The invention relates to a method for producing ceramic layers by spraying. A cold gas spraying method is used to produce polymer ceramics from pre-ceramic polymers. According to said method, a cold gas stream, to which particles of the pre-ceramic polymers are added via a conduit, is generated by a spray gun. The energy for creating a layer on a substrate is produced by injecting a powerful kinetic energy into the cold gas stream, thus preventing or significantly restricting the thermal heating of the cold gas stream. This permits the heat-sensitive pre-ceramic polymers to be spray-applied as a coating on a substrate using a cold gas spraying method. Polymer ceramics can thus be used in an economic method for the rapid production of layers with a relatively large thickness. The invention allows for example armoured layers, thermal protection layers and other functional layers to be produced.

A system and method for separating air into components uses an air dehydration membrane for removing water vapor from compressed air. Dried compressed air is then directed, from the dehydration membrane, into a gas separation module which may be a membrane system, different from the air dehydration membrane, or a pressure swing adsorption (PSA) system. The air dehydration membrane is made of a hydrophilic polymer having a permeability for water vapor which is greater than its permeability for air, and having low selectivity between oxygen and nitrogen. The air dehydration membrane has a hydrophilic coating, which itself may be a polymer. The coating does not affect the selectivity of the coated dehydration membrane with respect to oxygen and nitrogen, but does increase selectivity of the membrane with respect to water vapor.

A method and apparatus are provided for recovering a product from a filling line being used to fill containers with the product. The filling line comprises at least a filler, a pump, a check valve, compressed air/gas, a water source, and a holding tank containing the product, all interconnected by a product line.

Next, using a pump, the product is transferred from the holding tank through the filler line to the filler, and then into containers. The transfer continues until the pump is no longer primed with the product. The remaining product is then pushed with the compressed air/gas through the filler line into the filler and then into containers, thereby recovering substantially all the product remaining in the filler line. The product recovery method minimizes the amount of waste product that must be discarded from a bottling line.
