Abstract: A scraper for removing deposits from the exterior of a tubular member includes elements defining an outer jacket which has an inwardly open circumferential recess and two aligned axial openings, and a scraper element in the form of an elongate resilient wire bent to define a series of integral, concatenated, resilient segments, each pair of adjacent segments being connected through a bend or geniculation. All geniculations are received within the recess, and each segment of wire extends generally along a chord of the aligned axial openings. The positions of the chords are distributed around the circumference of the axial openings such that, in order for the tubular member to be accommodated through the aligned openings, the various segments must be deformed outwardly, whereby the resilience of the thus deformed segment urges it inwardly against the tubular member, and causes it to clean the tubular member as the scraper moves axially.

Abstract: The invention includes a method of cleaning a paint roller. The cleaning tool used in this method includes a flat, disc-shaped main body (10) having cleaning apertures (11a,b,c,&d) located thereon. Cleaning apertures (11a,b,c,&d) have diameters suitably smaller than the outside diameter, including the nap covering, of various popular roller sizes and nap thicknesses, such that a friction fit between the nap covering of such a roller and a cleaning aperture (11a,b,c, or d) is provided. Four access notches (12a,b,c,&d) extend from the circumference of cleaning apertures (11a,b,c,&d) respectively, to the circumference of main body (10). In this method, a cleaning tool is placed over the handle end of a roller, with the wire portion of the handle passing through one of the access notches (12a,b,c, or d) and into the center of one of the cleaning apertures (11a,b,c, or d).

Abstract: A tube cleaning article removes material from a tube in a well. A resilient member defines an encompassing path around a portion of the outer surface of the tube. The resilient member has a metallic inner surface biased toward the tube when the member is mounted on the tube such that the metallic inner surface scrapes material from the outer surface of the tube in response to reciprocating the tube relative to the resilient member. The metallic inner surface preferably presents more than two metallic edges along a longitudinal path of the outer surface of the tube. A particular implementation includes a split metallic ring. The split preferably extends at a transverse angle to the axial length of the ring. A spacer can be used with the ring. The spacer mounts on the tube such that the ring, when mounted on the tube, is between upper and lower portions of the spacer.

Abstract: A tool for distributing electrically conductive particles, and optionally abrasive particles, on the surface of a male, electrical jack connector and a tool for distributing electrically conductive particles, and optionally abrasive particles, on the surface of a female, electrical jack connector which tools can be interfitted so that each acts as a removable cover for the other. The tools can simultaneously clean while distributing particles. A method for using each of the tools.

Abstract: A safety valve to stop flow in the flow pipe (3), the safety valve including a drilling device (8) with its frame (6) to drill a hole in the flow pipe, a winding device (7) fixed to the frame of the drilling device and a band (4) wound with a winding device. The safety valve includes a sleeve to which sleeve a drilling device (8) and a winding device (7) have been fixed and the sleeve has been equipped with systems to fix it to the outside surface of the pipe (3).

Abstract: A rigging cable cleaning device primarily, although not exclusively, adapted for use on sailboat rigging cables, such as main sail cables, lanyard cables, and the like. The rigging cable cleaning device comprises an outer flexible fabric cover and an inner cleaning pad which can be folded or wrapped about a sailboat rigging cable. Holes with grommets are located on the ends of the outer fabric cover for receiving a releasable locking mechanism to thereby hold the cable cleaning device on a rigging cable. In this way, the device can be physically moved up and down or along the cable for cleaning same. The cleaning pad is removably attached to the inner surface of the fabric cover so that one type of cleaning pad can be substituted for another.
