  • Patent number: 6485281
    Abstract: The invention relates to repair devices for repairing impact resistant glass such as windshields and vertical glass. The repair device can be used to repair many types of damage to glass including cracks, bulls-eye breaks, star breaks, and angle wing breaks. For repairing breaks, the repair device removes air from the break before the resin is applied to the air-evacuated break. For repairing cracks, the repair device pushes resin into the crack while the device is slid along the crack. The repair device has a piston assembly including a piston, a piston casing, and a piston casing receiver; a mounting bracket; and a suction unit, including a manual vacuum pump. A resin is loaded into the piston assembly and delivered to the break or crack by hydraulic pressure, pneumatic pressure, and/or vacuum mode.

  • Patent number: 6458230
    Abstract: A process for preparing recyclable fiber composites, comprising bonding fibers with a polymeric bonding agent applied as an aqueous polymer dispersion to said fibers, the polymeric bonding agent comprising at least one addition polymer which, in the state of an aqueous dispersion, has a film forming capability at the temperature at which the addition polymer is combined with said fibers, and said aqueous polymer dispersion, when subjected to a change in pH, is converted into an aqueous solution of the addition polymer. The aqueous addition polymer of the addition polymer dispersion can contain protic acid groups, and the state of the dispersion can be converted to an aqueous addition polymer solution by raising the pH of the aqueous medium. Alternatively, the addition polymer may contain basic groups, in particular, amino groups, and its state as a dispersion can be converted into an aqueous addition polymer resolution by lowering the pH of the aqueous medium.

  • Patent number: 6454889
    Abstract: A structural member for reinforcement of asphalt and concrete roadways and other products, and which comprises a gridwork of warp strands and weft strands which are disposed at right angles to each other and so as to define an open structure. In one embodiment, the gridwork is impregnated with a thermosettable B-stage resin so as to interlock the strands at their crossover points and maintain the gridwork in a semi-flexible state, and after being applied to the product to be reinforced, the resin is heated to convert the same into a fully cured composite to thereby rigidize the gridwork and reinforce the product. In cases where the product to be reinforced is heated, such as asphalt paving, the heat of the product provides the heat necessary to fully cure the resin in situ. In another embodiment, the resin is fully cured to rigidize the gridwork prior to its being applied to the structure to be reinforced. A method of producing the resin impregnated gridwork is also disclosed.
