Deep-hardening steel with improved fracture toughness
This technology is particularly useful in applications requiring tools that are subject to severe wear or abrasion and that are also subject to breakage. Examples of such tools include ground-engaging implements used in construction, such as ripper tips, bucket teeth, cutting edges, and mold board blades. The steel has a fine-grained microstructure that contributes to excellent fracture toughness. This alloy steel is economical to produce and does not require relatively large amounts of chromium nor the inclusion of nickel or cobalt in the composition. The alloy responds to conventional quenching and tempering operations. Parts formed from this material do not require specialized equipment or heat treatment to provide high hardness, temper resistance, and toughness in the treated article. The technology has been commercialized.

Perfumed laundry detergent containing lipase
Lipases are of great benefit in laundry detergents since such detergents are better able to deal with greasy soil on cloth. Unfortunately, such detergents have a tendency to leave residual "sick" odors on the cloth. We have discovered that certain fragrance compositions are able to effectively counter the malodor associated with lipase in detergent products and detergent products containing such perfumes.

Laser-guided loading systems
Loading heavy items by crane or machinery into confined or small areas can be a very difficult task. Even the best of operators can sometimes misjudge distances or lower an object to quickly, resulting in damage to the goods or even worse, an injury. Weyerhaeuser has solved this problem with a unique Laser Guided Loading System.

Synthesizing stable optical polymers as media for active optical components
Electro-optical components are renowned for their instability over time. The coefficient progressively degrades and the performance of the component deteriorates correspondingly. This particular technology yields highly stable electro-optic polymers. The difference between this technology and others in the field is that the electro-optic material goes through two stages. Following polymerization, the chromophores are oriented using a polarizing electric field. They are then locked in their oriented position by thermochemical or photochemical cross-linking, through bonding the anchoring functional group of the chromophores with the complementary cross-linkable functional group. The cross-linked polymer material has an excellent electro-optical coefficient and its optical characteristics display great stability at high temperature.

Thin rechargeable lithium battery
A technology has been developed which makes it possible to manufacture both small and large area THIN batteries, for mobile telephone as well as for notebook PCs on the basis of existing, mature electro-chemical components (electrodes, separator and electrolyte). Electro-chemical components, presently used for the production of cylindrical batteries, can now be used for the production of thin/flat batteries as well.

Electrically conductive epoxy-based adhesive
This technology overcomes the disadvantages of most existing adhesives by providing an electrically conductive adhesive having both good conductivity and good adhesive shear strength. This adhesive cures at room temperature and exhibits desirable high-strength and electro-conductive characteristics. It is desirable to have a room temperature curable adhesive so that no temperature stresses are placed on the materials being bonded. Combining variously shaped metallic particles with a high-strength, high temperature epoxy results in a product having strength characteristics almost twice that of typical conductive epoxies and wide-range thermal properties. This epoxy is very useful in aerospace applications where these properties are required; however, its use is not limited to these applications, but can be extended to all those applications where an electrically conductive, high-strength adhesive might be desirable.

Rounded dry toner particles are chemically prepared
Toner for electrophotographic color printers is usually made by grinding extruded polymer blends into small particles. This leads to irregular particles with varying charge-to-mass ratios and the inclusion of tiny dust particles that result in agglomeration and sticking, especially in DEP printheads. The technique in this TechPak produces dry toner particles that are rounded to a specific ratio of long axis to short axis. Prototypes have been developed, but no commercialization yet.

Compact high-voltage power supply
With the trend towards miniaturization, demand has grown for extra high tension (EHT) power supplies that combine high operational reliability with small size and weight. Typical applications include portable test equipment and miniature cathode ray tube (CRT) displays. This novel design combines high frequency operation with component integration to produce a system that is compact, lightweight and offers excellent electrical performance. This EHT power supply has been developed to the prototype stage and tested in laboratory conditions.

Heterogeneous catalyst for acidic catalyzed chemical reactions
This technology describes a process for manufacture and use of a solid acid catalyst for acidic catalyzed chemical reactions. It provides solid acid catalysts suitable for the bisphenol A synthesis with stable catalytic properties, longer lifetime, and ideal macroscopic and physical properties. These technical requirements can be fulfilled by organopolysiloxanes containing sulfonate and mercapto groups being covalently anchored to the polysiloxane matrix via organic spacer groups. The systems enjoy the advantages of an inorganic polymer backbone and have a suitable capacity for sulfonate and mercapto groups, anchorage of which is guaranteed by Si atoms incorporated in the matrix by a trivalent bond.

Shock-absorbing seat belts based on metal wires
Differential stretching and breaking of metal wires embedded in a flexible matrix offers a technology for high-impact, shock-absorbing safety seat belts. The shock absorber is constituted by at least two wires with different impact absorption qualities. The two or more different wires allow for a multiple stage working in case of impact and for a tailored design. One of these wires may be an ultra-high tensile wire, developed and commercialized for tire reinforcement. Another of these wires may be a low-carbon steel wire with a much lower tensile strength but with a much higher elongation at break. All the wires can be integrated in a polymer matrix. Feasibility proven in tests.
