Abstract: Pivoting brush heads and associated machines in which cleaning of interior tube surfaces occurs by a forward non-cleaning pass of a pivoting brush head through a tube followed by a reverse cleaning pass where the pivoting brush head engages and cleans the interior surface. The pivoting brush head has a first position for the forward pass producing minimum engagement of interior tube surfaces, and a second position for the reverse pass of full cleaning engagement with the interior tube surfaces.

Abstract: Apparatuses and methods for filling bags are provided. Some apparatuses include a shovel and an elongate lever arm that may be arranged in a bagging or pivoting orientation, a storage orientation, and a shovel orientation. In the bagging orientation, the elongate lever arm may be rotatably coupled to the shovel. In the storage orientation, the apparatus may be configured for compact storage. In the shovel orientation, the elongate lever arm may extend proximally from the shovel to function as an extension of the shovel arm.

Abstract: There are disclosed embodiments for a paintball swab. For example, a disk is pivotably and slidably attached to the distal end of a rod so there is a proximal and distal limit along the rod. When the disk is at the distal limit, it is perpendicular to the longitudinal axis of the rod. When the disk is at the proximal limit, it is angled with respect to the longitudinal axis of the rod.

Abstract: A device for cleaning a chimney preferably includes a rod assembly, cleaning arms, fan blades, a camera, and a stabilizing/positioning assembly. The cleaning arms are provided on an assembly that includes a rotatable hub with the cleaning arms extending from the hub. The fan blades may also extend from the hub or they may be provided separately. The camera is continuously rotatable around the longitudinal axis to allow an uninterrupted 360° scan of the chimney. The stabilizing/positioning assembly is effective to position the cleaning assembly hub a pre-selected stabilizing/positioning distance from an interior wall of a chimney while the hub rotates in the chimney. The cleaning and fan hub(s) is driven by a cable surrounded by a casing that allows the cable to rotate in the casing without rotating the casing. Controls allow the operator to control the speed and direction of the cleaning arms and the camera.

Abstract: Applicant has disclosed a rotating cleaning tool to clean chimneys, ductwork, venting and pipe. In the preferred embodiment, the tool includes a cylinder having: two curved channels in its bottom or proximal face; and two curved channels in a distal or upper surface. Separate strands of monofilament line and/or wire can be placed in the channels with the ends of the strands sticking out from both ends of the channels and the cylinder. An animal nest remover—a flat (or round) bar with upturned ends—can be mounted onto a central post extending from the cylinder. The remover can be used with or without the strands. Upon bolting the tool together, the strands and/or bar are held in place. By attaching the tool to a pole or rod, and rotating the rod after being inserted into the chimney, creosote and other unfriendly materials can be removed from chimneys.

Abstract: The present invention relates to coating of tubes, and more particularly to a system and method for coating and/or renovating deteriorated or pitted tubes to extend tube life and enhance performance. Using this system and method a thin coating is applied to the interior of a tube such that the coating is uniform in thickness and covers all regions of the tube. The coating material may be selected to minimize changes in heat transfer or may be selected to provide for the change in working fluid within the tube such that the working fluid does not negatively interact with the tube material.

Abstract: Applicant has disclosed a rotating cleaning tool which uses multiple strands of monofilament lines or strands of wire or chains to clean chimneys, ductwork, venting and pipe. In the preferred embodiment, the tool comprises multiple components. One preferably is a cylinder having: two curved channels in its bottom or proximal face; and two curved channels in a distal surface. Separate strands of monofilament line and/or wire can be placed in the channels with the ends of the strands sticking out from both ends of the channels and the cylinder. Upon bolting the tool together, the strands are held in place. By attaching the tool to a pole or rod, and rotating the rod after being inserted into the chimney, creosote and other unfriendly materials can be removed from chimneys. Applicant prefers to connect his tool by the quick connect, coupling device disclosed in U.S. Pat. No. 6,688,800 to Kresge.

Abstract: An apparatus and method are provided to remove matte-sticking adhered to an inner surface of an inclined rear jacket of an exhaust gas hood for collecting exhaust gas discharged during the converter operation in copper smelting. Scraping means 10a˜10f are each provided with a scraping part 20 for scraping off matte-sticking by moving slidably across the inner surface of the rear jacket 8 by driving means 11 from a sidewall of the exhaust gas hood to at least over the centerline L of the width of the rear jacket 8. The scraping means are arranged in pairs at both right and left sidewalls of the exhaust gas hood 6 in multiple levels along the inclination of the rear jacket 8, thereby allowing the matte-sticking adhered to the rear jacket 8 to be removed over almost its entire surface.

Abstract: An attachment (10) for an inlet pipe (14) to a wet scrubber or other device comprises a sleeve (16) having an open end (18) adapted to be detachably connected to a flanged end (12) of the inlet pipe (14). A shaft (30) is moveable within the sleeve (16), and a scraper (34) is attached to one end of the shaft (30). The shaft (30) forms part of a pneumatic cylinder (40) attached to the other end of the sleeve (16). In use, the shaft (30) is reciprocally moved to cause the scraper (34) to dislodge particulates deposited within the pipe (14). Heated gas such as nitrogen or dry air is injected into the sleeve (16) to prevent scrubbing liquid from condensing within the sleeve (16) and thus inhibit particulate deposition therein.

Abstract: Attachment apparatus and method for interlocking attachment of a scraper blade with a drive shaft of a scraped surface heat exchanger includes a blade having dual attachment beams and a central locking member, and at least one pin having dual fingers each for interlocking with a respective attachment beam.

Abstract: Disclosed is a pipe cleaner apparatus that is attached to a pipe fusion machine. The pipe cleaner removes dirt, snow, mud, and other debris from the outer surface of pipe sections prior to the butt fusion process. The pipe cleaner may be a wiper through which the pipe slides, or may be a multi-piece scraper with spring loaded flaps that clean the outside surface of the pipe.

Abstract: A metal-debris magnetic scavenging tool useable inside a buried, horizontal metallic pipeline through an access opening which has been cut into the upper wall portion of the pipeline overhead where the resulting debris has collected. A raiseable/lowerable and rotatable array of magnets, surface exposed, and operating moveably as a unit, agitate and collect debris principally within an area-footprint which allows for clearance lifting and removal of collected debris through the access opening.

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.

Abstract: A tool for safely dislodging packed material from a discharge chute which includes an elongated shaft having a handle at one end and a probe tip at the other end.

Abstract: An apparatus for cleaning a chamber is disclosed. Scraping blades are rotatably mounted within a chamber and parallel to a longitudinal axis of the chamber. The scraping blades are rotated circumferentially within the chamber, scraping the inner surface of the chamber to prevent the buildup of particulate matter. An annular gear assembly provides mounting support for the scraping blades. A pneumatically operated pushrod assembly rotates the scraping blades circumferentially within the chamber. The annular gear assembly and pushrod assembly do not obstruct a direct path through the chamber.
