  • Patent number: 6666385
    Abstract: The plural component striping spray system and method involves mixing two spray components by pumping them under pressure from heated supply systems and converting them into a fine spray within a spray gun where they mix by impingement before being blown out through a common spray tip orifice. The initiation and termination of spray from the spray tip is controlled by a shutoff needle, and the design of the mixing chamber, needle and spray tip are such that no mixed material is allowed to stay in the spray gun to cure and freeze up the gun. When the components are a resin and a catalyst, pure catalyst is the first and last material sprayed from the spray gun. The system includes a recirculation system which can become operative when the operation of the spray gun is terminated.

  • Patent number: 6601887
    Abstract: A frame assembly for attachment to an elongated shaft of a tool. The frame assembly is arranged to increase the leverage and handling capabilities of the tool. The frame assembly comprises a generally triangularly shaped frame having a housing portion leg, a forward leg and a rearward leg. The forward and the rearward legs meet at an apex of the frame assembly. A securement mechanism secures the housing portion leg to the shaft of the tool. An articulable handle is arranged on the apex of the frame assembly to permit the tool to be leveraged by a user of the frame assembly in an enhanced manner.

  • Patent number: 5169448
    Abstract: An apparatus, for determining the degree of tackiness of a surface of a body, comprises a closed chamber with inlet and outlet openings; a support for the body within the chamber; a fan for providing an airflow directed toward the surface of the body within the chamber; a powder dispenser for releasing powder into the path of the airflow upstream of the body surface, the powder being adapted to be carried by the airflow thereby to permit the powder to impinge against the body surface; whereby the amount of powder adhering to the body surface after a period provides a measure of tackiness of the surface.
