  • Patent number: 10852104
    Abstract: A rifle scope and mount system provide a means of securely attaching a telescopic sight to a firearm such that a person installing the scope may set it at an appropriate eye relief distance at any of a number of finely spaced apart locations ahead of the shooters head and sighting eye. The scope and mount system also provides means for radial positioning of a scope within its clamp rings so that a local angular discrepancy in the alignment of horizontal datums established by the rifle as held by a user and local horizontal datums established by a mounting rail or similar scope mounting features on the rifle may be overcome by an affordance for securing the scope at an angular displacement substantially equal and opposite to the discrepancy inherent within the weapon.

  • Patent number: 10352658
    Abstract: A scope and mount block assembly for a rifle includes a scope having sets of spaced apart ribs for seating into complementary arcuate grooves in scope mount components. An underside keyseat in the scope aligns with a complementary keyseat in a scope mount block, and a key residing in the combined volume of both keyseat enforces this alignment. The scope mount blocks clamp to any standard rail such as a Picatinny rail. When the scope is removed, leaving the blocks in place, it can be reattached so that the key reestablishes its alignment to the rifle and no re-sighting of the scope is required. Also, careful selection of pitches for the scope ribs and for spaced apart features for engagement of the mount blocks to a mounting rail can offer much finer incremental location of the scope on the rifle for more precise adjustment of eye relief.

  • Publication number: 20070102686
    Abstract: A method for producing a polymeric material comprises reacting a first reactant with a second reactant. The first reactant comprises anhydrous phosphorous pentoxide and the second reactant comprises an alcohol. A method for producing a polymeric salt material comprises reacting a first reactant comprising an amine with a second reactant comprising a phosphate ester.

  • Publication number: 20060175586
    Abstract: A method for forming a fire resistant material is disclosed. The method comprises providing a plurality of expandable beads of a polymeric material. The beads are coated with an exfoliable graphite. The exfoliable graphite is adhered to the beads with a resin having a solubility parameter of the polymeric material. The beads are thereafter caused or allowed to expand and fuse.
