Abstract: A system and method for vacuum bag assembly fabrication via the vacuum bag method which reduces the amount of trapped air. The inventive system includes a chamber adapted to contain a vacuum bag and first and second evacuating mechanisms. The first evacuating mechanism serves to evacuate the bag and vent to atmosphere. The second evacuating mechanism serves to evacuate and vent the chamber to atmosphere. Thus, generally, the inventive method includes the steps of placing a vacuum bag lay up in an air tight chamber; and evacuating the vacuum bag lay up and the air tight chamber at the same time. In practice, the assembly would consist of at least two components and a heat curable composition. The components can be parts to be bonded together or layers of cloth to be made into a laminate. In this case, the heat curable composition would be a catalyzed adhesive or resin.

Abstract: A plurality of sensor units are distributed over an area and communicate via a network with a central monitoring unit. The sensor units include sensor arrays that provide them with raw data in response to the presence of selected compounds in the ambient fluid. The raw sensor data is then processed to compute a local profile, which (a) illustrates a change in the compounds in the fluid from their normal state (change detection) , (b) indicates the presence and total concentration of foreign compounds in the fluid (presence detection), or (c) details the composition and concentrations of defined classes or individual species of compounds in the fluid (composition detection). The local profiles from the individual sensor units are then used to compute a spatial and temporal map for the compounds in the fluid.

Abstract: A soldering tool that comprises a selected salt, including Group I and II halides such as potassium chloride, for example, that is transparent to infrared energy. A selected salt is formed into a tool having a specific shape for placement during soldering. The tool is used to position and hold component leads during infrared soldering. The tool is formed into a shape that matches the shape of a component and whose leads are to be soldered. The tool is configured so that it may be disposed over the component so that the tool contacts the leads and causes them to contact pads to which the leads. The tool is reusable in that after showing signs of wear, it may be recycled, reformed, and reused. An infrared soldering method for soldering leads to pads comprises the following steps. The tool is fabricated from a material that is transparent to infrared radiation. The tool formed into a shape that matches the shape of the component and contacts the leads to cause them to contact the pads.

Abstract: A transportable ozone neutralization system (10) for neutralizing a chemical compound is provided. The neutralization system (10) includes an enclosure (12) for substantially containing a container, such as a chemical munition (28), within which the chemical compound to be neutralized is contained. The neutralization system (10) further includes a liquid phase neutralization system (62) and a vapor phase neutralization system (100) which utilize ozone manufactured from the air, to contact the liquid and vapor phase chemical compounds through a solvent. The system neutralizes the chemical compound by the action of ozone in breaking the chemical bonds with the compound.

Abstract: The generator incorporates plural tubular outer electrodes retained within a cylindrical pipe housing. The inner electrode is a metal strip with a helical twist. It is spaced from the outer electrode by a cylindrical dielectric. Circular plates are utilized for supporting and spacing the electrode tubes, and for manifolding gases to the electrode and making electrical contact with the inner electrodes. The circular plates also act as terminals for electrically connecting the electrodes across the source of high voltage.
