  • Patent number: 6689199
    Abstract: A method of introducing small amounts of a refractory element into a vapor deposition coating. A second material (30), containing at least two elements which are desired to be deposited as a coating on a base material, has placed over it a first material (20) substantially comprising such two elements and a refractory element. The first material (20) is adapted to permit transport of the at least two elements in the second material (30) through the first material (20) when the first (20) and second (30) material are in a molten state and in touching contact with the other so as to permit evaporation of the two elements and the refractory element from an exposed surface. Heat is supplied to the first (20) and second (30) materials to permit evaporation of the at least two elements of second material (30) and the refractory element in the first material (20), and the resulting vapors are condensed as a deposit on a base material (50).

  • Patent number: 6682513
    Abstract: A tampon showing improved leakage protection through improved expansion characteristics is disclosed. The tampons disclosed demonstrate these improved expansion characteristics particularly in the width dimension without introducing new drawbacks. Preferred tampons are described which are compressed to an initial size comparable to current tampons, but which expand to a width exceeding that achieved by current tampons. Such increased expansion is preferably accomplished without an increase in the total absorbency of the tampon. Tampons of various absorbencies are disclosed having increased total expansion in the width direction compared to current tampons. Additionally, tampons of various absorbencies which expand to a greater degree in the width direction under pressure are also disclosed. Tampons of various absorbencies which expand at a rate exceeding that achieved previously are also disclosed.

  • Patent number: 6660339
    Abstract: The present invention relates to a process, preferably a continuous process, of coating a substrate, which allows water vapor and preferably air permeation, with a hydrophobic coating. The process preferably uses a thin film vacuum condensation step to create a monomer coating which is cured in situ after the coating. The process has the benefit of allowing continuous operation and providing an alternative to existing processes for hydrophobic coating. The substrates are coated such that the water vapour permeation sites are not blocked by the coating to maintain the desired breathability. The static water contact angle on the surface of such substrates is more than 95°.

  • Patent number: 6613248
    Abstract: Strontium, calcium, strontium calcium, strontium calcium magnesium, calcium magnesium aluminates, and strontium borates activated with Pr3+ exhibit characteristics of quantum-splitting phosphors under VUV excitation. A large emission peak at about 405 nm under VUV excitation is used conveniently to identify quantum-splitting phosphors. Improvements may be achieved with addition of fluorides or boric acid as a flux during the preparation of the phosphors. It is also possible to predict improvement in quantum efficiency by observing the ratio of emission intensities at about 480 nm and about 610 nm.
