Non-Fluoro-Based Textile Repellency Treatment

A company seeks a ready-to-use, non - fluorochemical - based repellent solution for oil- and water-borne stains for application on textiles. The textiles may be cotton, wool, or synthetic, or a blend of natural and synthetic fibers. This material may be fully formulated or partially formulated in a solventfree delivery solution.

One-Megapixel Infrared Light Detector

A company seeks a detector array for the infrared region to detect two-dimensional radiation patterns. The sensor should have 1000 x 1000 pixels (or at least 512 × 640 pixels), which are individually addressable. The detector array is comparable to a high-speed CCD chip, but must have high sensitivity in the infrared around 1,300 nm.

Cooler, Quieter Jet Engine for Light-Sport Aircraft and Ultralights

A small jet engine is suitable for light-sport, ultralight, and experimental aircraft, and can replace the vibrating piston engine and propeller combination used in most sport aircraft. Exhaust heat is minimized for safety to 750 °C, so that a suitably insulated cowling can be touched. By minimizing the heat, sound absorbers can be used so that sound output of the engine is also minimized to about 200 dB or less at a measured distance from the exhaust. The engine provides much less vibration than does a conventional propeller and piston engine combination. The engine provides about 500 N (almost 370 foot-pounds) of thrust using a small compressor diameter and a high rotation speed. This engine produces inherently less noise, and in addition uses sound attenuation such as glass fibers and other materials formed as part of the exhaust tube, boundary layers, and other techniques. Using such sound attenuation, as well as bypass air, also serves to insulate the heat-producing portions of the engine from pilot, passengers, and ground personnel.

Low-Cost Engineered Properties for Non- Wovens, Films, and Laminates

A suite of nonwoven technologies offers low-cost mechanical processes that impart specific engineered properties to commodity-priced nonwovens, films, and laminates, and even to non-polymeric materials. A wide range of textures, controllable permeability, aperturing, multilayer composites, elasticity without elastic chemistry, and other features comprises various aspects of the suite. Many of the technologies operate at room temperature, without adhesives, and are suitable to high-speed lines (in excess of 500 FPM). They are compatible with production lines that may need to start and stop. They enhance the performance of low-cost materials — adding strength, puncture resistance, stretch, texture, permeability, and more — in ways that melt-based systems can achieve. They open potential new markets such as a new category of disposable fabric home goods (sheets, curtains, and pillows), new packaging options, and agricultural products.

Binder Solutions for the Manufacture of Molds and, Cores in Metal Castings

Binders used for molding are typically self-setting, so that after mixing two or more binder components into sand, there is a short delay before the mixture starts to set hard. Binders used for core-making are typically gas-cured. A company seeks an environmentally acceptable binder system that could be based on inorganic, “clean” organic, or hybrid derivatives, and offers an immediate advantage over current systems in terms of health, safety, and environmental issues.

Moisture Release Technologies

A company seeks technologies enabling a woven or nonwoven substrate to contain liquid/fluid that can be released by applying pressure (to yield a moist/wet substrate). They are interested in solutions that will enable water or other liquids/ fluids to be contained within a substrate and then released under moderate pressure (for example, by squeezing the substrate in your hand). The technology solution must be able to incorporate sufficient liquid content in the substrate so that when pressure is applied, approximately 75% of that substrate unit becomes moist.
