  • Noise insulating mounting bracket for an automobile on-board air compressor
    Patent number: 6260814
    Abstract: An air compressor 10 for an air leveling suspension system of a motor vehicle is mounted on a vibration reducing bracket 12. The bracket includes a bottom panel section 16 that has a perforated metal grid 40 embedded therein. Side walls 18 extend to an open top 20. A first set of brass inserts 24 are embedded into a plurality of tiers 22 that are spaced between the closed bottom panel section 16 and open top 20 to mount the air compressor 10.

  • Acidic glass fiber binding composition, method of use and curable glass fiber compositions
    Patent number: 5505998
    Abstract: Described is an acidic glass fiber binding composition comprising an aqueous soluble phenol formaldehyde resin having low free formaldehyde, an effective amount of a formaldehyde scavenger, and an effective amount of a strong aqueous soluble acid, wherein the composition has an acidic pH and the solids content ranges from about 1 to about 30% by weight of the total composition. Also described is a method of binding glass fibers such as newly formed warm glass fibers at junctions of the fibers by applying the composition as described above to the fibers and then drying the composition. Also described are B-staged and C-staged glass fiber compositions having a alkylamine content less than 5 ppm.
