  • Patent number: 6875469
    Abstract: The present invention provides an adhesive filament-bearing adhesive tape comprising an adhesive substrate adapted to be releasably adhered to a surface to be coated, and a filament releasably adhered to an edge of that substrate, that is useful in trimming a coating applied to a surface. The invention further provides a method of trimming a coating applied to a surface comprising applying to the surface to be coated a masking material to define the area to be coated and a filament of material of sufficient tensile strength to cut the coating material; applying coating material to the surface; allowing the coating material to dry or cure until it obtains sufficient strength to hold a cut edge; and drawing the filament through the coating to cut the coating.

  • Patent number: 6755348
    Abstract: A method and system are provided for dispensing a colored polymerizing composition. Two reactive components and one color component are pumped from respective containers at a metered volume. The color component, which is preferably a low-viscosity automotive paint is injected into either the first or second stream of reactive component at a point immediately prior to mixing all components in a dispensing device for dispensing the resulting colored fluid mixture onto a surface to be coated. The mixture may be dispensed by pouring or spraying onto the surface. The method and system are particularly useful for mixing and dispensing colored polyurethane or polyurea coatings, such as for spray-on truck bed liners.

  • Patent number: 6131823
    Abstract: A dispensing gun for atomizing a fluid under pressure with pressurized air includes a body having two fluid inlet structures and an air inlet structure defined in the body. An elongate barrel housing projects outwardly from the body. A longitudinal air passageway communicating with the air inlet structure, and a longitudinal fluid passageway communicating with the fluid inlet structure are defined within the barrel housing. An atomizing structure for atomizing the fluid under pressure with the air under pressure is connected to the distal end of the barrel housing.

  • Patent number: 5388761
    Abstract: An apparatus and method for mixing and delivering plural liquid components in a selected volume ratio. For each component, a separate motor drives a separate rotary gear pump that delivers the component to a common mixing and delivery device (spray gun). The speed of each motor, and correspondingly the volume of fluid delivered by that pump, is determined by a respective programmable computer. The individual computers are interlinked, with one master computer and the rest slave(s). Desired motor speeds are input into the computers in a selected ratio. A change in the speed of the master motor therefore produces a corresponding change in the speed of a slave motor according to the ratio. Actual motor speed is monitored and transmitted to the respective computer for feedback control. A simple manual ratio test is provided for calibration of the system. Each pump is magnetically coupled to its respective motor drive shaft.
