  • Patent number: 10323443
    Abstract: A vehicle includes a first member and a second member moveable relative to the first member. A compliant member is compressible between the first member and the second member. A compression control device is attached to one of the first member and the second member for engaging another of the first member and the second member, or the compliant member. The compression control device is moveable between a first position and a second position. When disposed in the first position, the compression control device is not engaged with the first member, the second member, or the compliant member, and allows compression of the compliant member into a first compressive state. When disposed in the second position, the compression control device is engaged with one of the first member, the second member, or the compliant member, and is operable to compress the compliant member into a second compressive state.

  • Patent number: 7892515
    Abstract: Carbon with mesopores (about two to fifteen nanometers in average pore size) is made using sucrose as a source of carbon, and silica and phosphoric acid as templates for the mesopore structure in the carbon. A silica sol is prepared in a water/ethanol medium and sucrose is dispersed in the sol. Phosphoric acid may be added to the sol to control pore size in the mesopore size range. The sol is dried, carbonized, and the silica and phosphate materials removed by leaching. The residue is a mesoporous carbon mass having utility as a catalyst support, gas absorbent, and the like.
