Abstract: A swab device for cleaning the barrel of a paintball gun has a first shaft, a second shaft and a flexible connector overmolded over ends of the first and second shafts to fixedly couple the flexible connector to the first and second shafts. Absorbent material can be disposed over the first and second rods. The flexible connector can be made of rubber or silicone. The flexible connector is configured to flex and to automatically return to an original linear orientation after the flexible connector has been flexed. The flexible connector can have one or more openings on a surface thereof that facilitate flexion of the flexible connector.
Abstract: A cleaning tool for a pipe, the cleaning tool being moved inside the pipe while rotating in the main about the longitudinal axis of the pipe, and the cleaning tool including, in addition to a mount, at least two cleaning bodies which are rotatable about their respective individual shafts, the cleaning bodies being provided with an uneven surface, at least part of the external active uneven surface of the cleaning bodies facing the internal mantle surface of the pipe.
Abstract: In embodiments of the present invention, a gutter-cleaning device comprises a housing containing an impeller drive facility, the housing configured to fit into a gutter, an impeller, disposed at an end of the housing and driven by the impeller drive facility, and a transport facility for transporting the housing along the gutter.

Abstract: A compactable paintball marker squeegee adapted to compact for carrying on the playing field for paintball games. The squeegee is designed to compact into smaller arrangements while providing the capability of wiping paint out a marker barrel. The present invention is designed such that the system will lock into an elongated position and may be unlocked and flipped closed with a single hand motion for compaction during play of a paintball game. Additional improvements provide for a protective design to provide improved insertion into clothing with a protected cleaning head, and improved cleaning head movements through a pear-shaped connection aperture for the pivoting head.

Abstract: A pig for use with a tubular bore wherein the pig is comprised of a body which supports a plurality of turbine blades wherein the blades mechanically break down and remove debris from the tubular bore. The blades have a profile which allows forward movement and rotation about a longitudinal axis when acted upon by a propulsion fluid traveling through the tubular. In an alternative embodiment the blades are mounted on a stabilizer body to allow simultaneous centralization and cleaning.
