Tamper-Evident Packaging for Consumer Products

Tamper-evidence properties are often achieved by adding secondary packaging such as foil seals or heat-shrink seals that inflate the cost of the container. This invention provides a proven technology to produce an injection-molded, tamperevident plastic lid for a container that can be used in the absence of a foil lid, and yet provides an effective hermetic seal. Even after its initial opening, the lid reseals air- and water-tight. It is available in 1,000-ml and 500-ml sizes, but can be molded to requirements. This product is ideal for yogurt, ice cream, sauce, and even non-food items such as washing powder, paint, and products where protection against moisture is required after opening. Most containers that have a foil seal also have a secondary lid that fits loosely on the tub after the foil seal is removed. Such lids do not offer water– and air–tight sealing. Secondary seals such as foil seals add to the cost of the packaging and prevent the product from being screened by metal detectors to detect metal parts in the final product.

Dissolvable Paper/Packaging Material

A company is searching for a disruptive technology relating to dispersible packaging materials. The material should easily dissolve in cold water and be 100% biodegradable in a short space of time, without compromising the strength and performance of the material for its given application. While paper-based products are expected as potential solutions, the material could also be polymer-based, a film, or bio-based. It should be manufactured from sustainable raw materials and have low toxicity for both final product and processing aids.

Anchoring Technology to Hold an Active Ingredient Within a Targeted Depth of Soil

A company seeks technologies that enhance the duration that herbicides, insecticides, fungicides, and similar products are held at a targeted depth within the top layers of soil. Duration should be between 30 and 60 days. The targeted depth varies with the crop plant, soil type, and pesticide, but is usually between the surface and 3-4" deep. The technology should not be persistent and should not affect the following crop. It must degrade chemically or biologically in the soil.

Real-Time Dogfight Guiding System

Successful performance of BFM (Basic Flight Maneuvers) presents the greatest challenge facing combat pilots. Acquiring and maintaining the required skills for dogfights is a long, complicated and costly process. The solution is a system that provides automatic assessment of a situation and automatic recommendation guidance to the pilot. Re c - ommended guidance on the Helmet Mounted Sight/Head Up Display Solution allows different BFM methods and simulates activation of various missiles. The software performs accurate, real-time situation assessment and provides a dynamic guidance to the pilot. These guidance and recommendations will help to enhance the performance of the crew during the participation in a closein maneuvering air combat training. A data link provides real-time relevant data of the trainer aircraft. Aircraft and weapon system performance and limits are input to system software. The system provides constant assessment of the BFM, and a unique algorithm analyzes and provides the realtime solution.

Fluorinated ZDDP Improves Mileage and Reduces Engine Wear

This technology takes ZDDP — Zinc Dialkyl Dithiophos - phate, an anti-wear oil additive — and enhances it by adding fluorine to the chemical backbone. The resulting new molecule improves engine fuel economy by 3%, reduces engine wear from that available with conventional ZDDP, and contains from 100 to 250 ppm of phosphorus to prolong the life of catalytic converters. It contains about a third of the phosphorus in conventional ZDDP, and the phosphate compounds it does produce bind to the fluorine and become embedded in the tribofilm deposited on the contact surfaces. The additive is a liquid, and presents no suspension issues. In grease and in similar lubrication applications, the new molecule is effective at both low-load/high-speed applications and at high-load applications. Fluorinated ZDDP has application in all internal combustion engines; in gasoline, diesel, and natural gas generators; in transmissions and differentials; and in grease and lubrication applications (such as wheel bearings, CV joints, journal boxes, and automated machinery).

Rocket Engine Altitude Simulation Technologies

John C. Stennis Space Center is embarking on a very ambitious era in its rocket engine propulsion test history. The first new large rocket engine test stand to be built at Stennis Space Center in over 40 years is under construction. The new A3 Test Stand is designed to test very large (294,000 lbf thrust) cryogenic propellant rocket engines at a simulated altitude of 100,000 feet.
