  • Patent number: 6673257
    Abstract: A thermal cutoff member and compositions used to manufacture such members are described herein as including at least two organic compounds which, when sufficiently combined, give rise to a component which has a lower melt transition temperature than the initial organic compounds prior to combining the same. The thermal cutoff member is generally utilized in a thermal cutoff construction having an electrical switching unit that changes its operating condition when the member therein melts by being heated to a certain temperature for the particular material that forms the member being utilized.

  • Patent number: 6645921
    Abstract: The invention relates to an improved process for producing organomolybdenum compositions with high molybdenum content that are highly useful as lubricant additives, in which the process involves reacting a fatty oil with a diamine, followed by reaction with a molybdenum source. The process of the present invention does not require a volatile organic solvent to promote molybdenum incorporation and produces an organomolybdenum composition having a high molybdenum content. In addition, the process can be conducted in the absence of sulfur and phosphorus-containing reactants.

  • Patent number: 6596888
    Abstract: Single imido tungsten imido precursors are described for the deposition of tungsten nitride on a substrate by processes such as metal organic chemical vapor deposition. The precursors may be employed to form diffusion barrier layers on microelectronic devices. A method for forming tungsten nitride layers includes the steps of providing a tungsten imido species having the formula LyW(NR)Xn, where R is a carbon containing group, y is an integer between 0 and 5, n is an integer between 0 and 4 and Ly and Xn are selected from the group of non-imido ligands. The single imido tungsten imido species is flowed to a surface of a substrate where the single imido tungsten imido species decomposes to form a tungsten nitride layer.
