September 3, 2012. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent References 2661494 3306310 3436783 Method of cleaning tubular members on a rig floor Cleaner for tubular pin and box ends Thread cleaner with rotatable and adjustably supported brushes Method and apparatus for injecting foam into a pipeline, including an inflatable plug Apparatus for cleaning threaded pipe ends Tool joint cleaner Pipe thread cleaner InventorsAssigneeApplicationNo. 940306 filed on 09/03/1992US Classes:134/110, By filter or strainer only (except work-spraying head)134/167C, Conduit cleaner134/170, With means to apply fluids both internally and externally134/178Coordinated with valve thereforExaminersPrimary: Coe, Philip R.Attorney, Agent or FirmInternational ClassB08B 003/02AbstractA system for cleaning both the box and pin ends of tubular members, recovery of the fluid residue, filtering of the residue to recover the heavy solids, and disposing of each of the components of the residue in an environmentally safe manner. A first housing positionable over the end of a tubular member; a first bladder expandable from the housing to seal around the outer wall of the tubular member; a plurality of jets positioned adjacent the threads of the tubular member, so that as the jets are rotated around the threads, a high pressure fluid spray cleans the threads of the member; a second bladder expandable from the end of the jetting means for sealing the inner bore of the member beyond the threads, so that all fluid jetted into the housing from the jetting nozzles is captured within the housing and flows from the housing, and no fluid flows beyond the threaded pipe end either along the inner or outer walls of the tubular member. The fluid is then collected, filtered, and the filtrate is disposed as wastewater, and the filters containing the filtered solid is placed in environmentally safe sealed containers for disposal.Field of SearchBy filter or strainer only (except work-spraying head)With movably or flexibly mounted spray or jet applying conduits or nozzles Conduit cleaner With movable means to cause fluid motion (e.g., pumps) Conduit cleaner With means to apply fluids both internally and externally With guiding means to restrict motion to rotation, to swinging, or to an annular closed or to a curved path With motor therefor Work circumposable or opposed fluid-applying jets or plural pipes With closable work-treating chambers | |
