  • Wide short ski
    Patent number: 5603522
    Abstract: A wide short ski preferably has a length within the range of 148 to 173 centimeters, The forward, shovel portion of the ski has a maximum transverse width in the range of 110 to 120 millimeters. The ski also has a rearward, heel portion with a maximum width in the range of 105 to 115 millimeters. Both the shovel and tail portions taper into a narrower waist portion where ski bindings are mounted. The ski has symmetrical sidecuts in the range of 14 to 28 meters. The ranges just specified produce an optimized, energy-efficient ski for a broad range of snow conditions.

  • Polymer blend composition of fluorinated elastomers, thermoplastic polymers and thermoplastics elastomers
    Patent number: 5371143
    Abstract: Fluorine-containing thermoplastic elastomeric compositions comprising: (A) a continuous phase comprising: (1) about 0 to 90 weight percent of thermoplastic polymer having a melt temperature or glass transition temperature greater than about 150.degree. C., and (2) about 10 to 100 weight percent of block thermoplastic elastomer having a melt temperature greater than about 150.degree. C.; and (B) a disperse phase comprising particles or domains of cured, fluoroelastomer composition. Such compositions are preferably prepared by dynamically vulcanizing the ingredients of the fluorine-containing thermoplastic elastomeric composition.
