摘要:
The invention relates to an analyzer for the identification of explosives and/or chemical warfare agents, with a neutron source which causes the emission of characteristic &ggr; quanta, whereby the analysis system consists of a mobile frame to which a neutron source and a detector as well as a holder for the object are attached, with a neutron generator which contains deuterium as the target, generates neutron pulses by periodically repeated, pulsed bombardment of the target and is controlled so that short neutron pulses are emitted and repeated periodically, whereby the detector is controlled so that in cycles it detects &ggr; quanta promptly emitted from the object due to inelastic neutron scattering and neutron capture, within at least two consecutive temporal measurement windows, whereby the first measurement window at least partially overlaps temporally the neutron pulse and the subsequent second measurement window does not, whereby in the first measurement window &ggr; quanta are essentially detected due to inelastic neutron scattering and in the second measurement window they are detected due to neutron capture.

A flexible, high pressure, tubular storage vessel for storing and dispensing a compressed gas. The vessel has a gas impermeable inner core member comprising a flexible material and defining an inner diameter of a fluid-carrying channel adapted to store the compressed gas. A flexible reinforcing material is circumferentially disposed about the inner core member. The flexible reinforcing material is surrounded by an air-tight gas barrier wrapping defining an outer diameter. The vessel is configured to be coiled or shaped having a plurality of bends. The bend areas may have a variable inner diameter and are preferably provided with additional reinforcing material.

An electrochemical engine for a vehicle comprises a storage tank containing hydrogen-retention material which reversibly takes-up and stores hydrogen at a hydrogen-storage temperature and releases it upon heating to a release temperature. A fuel cell stack using the released hydrogen produces electricity and heat by-product. A primary coolant flow circuit extends from a radiator, through the fuel cell stack and the storage tank, and back to the radiator, and has a coolant-distribution valve intermediate the fuel cell stack and the storage tank. A bypass coolant flow line extends from the coolant-distribution valve to the radiator. During operation, the heat by-product of the fuel cell stack is transferred via the primary coolant flow circuit to the storage tank for heating the hydrogen-retention material to release hydrogen for fueling the fuel cell stack. The electrochemical engine further comprises a heat generator within a superheater coolant flow loop having a bypass valve intermediate the storage tank and the radiator operable to keep coolant within the superheater coolant flow loop and a secondary pump to circulate the coolant. Coolant in the superheater coolant flow loop is heated by the heat generator and circulated through the storage tank to further release hydrogen gas from the hydrogen-retention material.

A process for producing borazane from boron-nitrogen and boron-nitrogen-hydrogen containing BNH-waste products. The process includes reacting the BNH-waste products with a hydrogen halide, having the formula HX, wherein X is selected from the group consisting of F, Cl, Br, I, and combinations thereof, to form any of the following: a boron trihalide, having the formula BX3, an ammonium halide, having the formula NH4X, and hydrogen. The boron trihalide is then reacted with the hydrogen to form diborane, having the formula B2H6, and hydrogen halide. The ammonium halide is then converted to ammonia, having the formula NH3, and hydrogen halide. The diborane is then reacted with the ammonia to form borazane, having the formula BH3NH3.

摘要:
A cryogenic gas storage system for optimal desorption of adsorbed gases, wherein a gas storage material is subjected to enhanced, ample selected recirculation of gas of the same type as the adsorbed gas, at suitable temperature and pressure, so as to supply of heat energy to the material and thereby provide optimal desorption of the gas. Output gas is heated by ambient heat or dissipation heat utilizing at least one heat exchanger. A portion of the output gas goes to a gas consumer, the remainder is fed back to the container.

摘要:
A gas storage system that stores a gas by cryo-adsorption on high surface materials. The gas storage system includes an outer container having insulated walls and a plurality of pressure vessels disposed therein. Each of the pressure vessels includes a high surface material. A manifold assembly distributes the gas under pressure to the pressure vessels where the gas is adsorbed by cryo-adsorption using the high surface materials. A cooling fluid is provided within voids between the pressure vessels to remove heat as the pressure vessels are being filled with the gas.

ECD with a non-radioactive electron source for generation of ions in a reaction chamber. The reaction chamber consists of two partial chambers, of which one is evacuated and contains the electron source, and the other contains connections for the feeding in of analysis gas as well as a collector electrode for detecting ions. The partition between the two partial chambers is permeable for electrons from the source but impermeable for gas molecules. The electron source may be a thermoemitter or a photocathode, which is irradiated from the outside through a window. In this way, contact between the analysis substance and the electron source is prevented, which increases measurement stability.
摘要:
Ion mobility spectrometer with a non-radioactive electron source to generate ions inside a reaction chamber. The reaction chamber consists of two partial chambers, one of which is evacuated and comprises the electron source, and the other one is connected to the drift chamber of the IMS via a shutter grid. The partition wall between both partial chambers is transparent to electrons but impermeable for gas molecules. The electron source may comprise a thermoemitter or a photocathode, which is illuminated from outside through a window. In this way, any contact between analyte and electron source is avoided, thereby improving the measuring stability and enabling operation in positive and negative mode.
