| 20090205151 | Luer Cleaner with Self-Puncturing Reservoir - A luer cleaner assembly ( | 08-20-2009 |
| 20090282631 | Boiler cleaning apparatus and method - The boiler cleaning apparatus and method provides for cleaning the exterior surfaces of a heat exchanger. The apparatus includes tools for temporarily spreading and holding open a tube bank to form and gain access to tube lanes. Once access to a lane is attained, a nozzle assembly having an outlet for blowing high velocity cleaning fluid is selected from a group of nozzle assemblies. The selected nozzle assembly will have an outlet for blowing fluid in a direction that effectively cleans the tubes adjacent the opened lane. After the tubes are cleaned the tool for holding the lane opened is removed and the process is repeated for another lane. | 11-19-2009 |
| 20100095467 | Scraping tool - A stationary frame is positioned in surrounding relation with the surface of a polyethylene conduit to be prepared for scraping preliminary to performing electrofusion on the conduit by a keyhole operation in an excavated underground location. A scraper tool is mounted on the frame in a fixed longitudinal position to rotate around the surface of the conduit. A cutting blade of the scraping tool extends longitudinally a preselected length on the conduit into contact with the surface of the conduit. Rotation of the scraper tool carries the cutting blade completely around the surface of the conduit to remove a uniform layer of material from the surface of the conduit. Any out of roundness existing in the conduit is removed before the scraping operation is commenced. Uniform compression is applied by split clamps surrounding the conduit. Compression of the clamps restores the conduit to a concentric configuration preliminary to the electrofusion operation. | 04-22-2010 |
| 20100122423 | Device for Simultaneously Cleaning and Deburring Pipe - A tool simultaneously deburrs and cleans an end of a pipe. The tool may have a casing that combines a mechanically abrasive cleaning mechanism and a cutting mechanism. The casing may have the cleaning mechanism and cutting mechanism aligned on an axis with the pipe, so that the outer surface of the pipe may be cleaned while the internal diameter may be cut or deburred. Some embodiments may be hand held devices that may be gripped in the palm of a hand, while other embodiments may be mounted on a drill or other powered mechanism. | 05-20-2010 |
| 20100212094 | SANITIZING FLUID DISPENSING DEVICE - A device and method for dispensing sanitizing fluid via a ring with disjoined ends. The ring flexes to enlarge a gap between the disjoined ends for placement of the device about a shopping cart handle. The ring also flexes to reduce the gap for wiping the shopping cart handle with a moistened wipe that is retained on an inner periphery surface of the ring. The ring includes a refillable cavity forming a reservoir within the body to provide a store of sanitizing fluid that is dispersed through an opening in the inner periphery of the ring onto or through the moistened wipe. The reservoir may be refilled by opening a plug or diaphragm disposed on the outer periphery of the ring and inserting a refill needle. | 08-26-2010 |
| 20100281640 | In-situ bwr and pwr CRUD flake analysis method and tool - The invention provides a method and tool to perform an analysis of CRUD on a nuclear fuel rod. The method recites providing a nuclear fuel rod with a layer of CRUD on an exterior of the fuel rod, scraping the CRUD from the fuel rod with a CRUD scraping tool and collecting CRUD flakes from the CRUD scraping tool. The method also provides for sorting the CRUD flakes into particle fractions, and analyzing the CRUD with a scanning electron microscope, wherein the scraping tool has a blade with a rigidity that is matched to an anticipated CRUD deposit shear strength. | 11-11-2010 |
| 20110239385 | Device for the Partial Removal of Coating from Pipes, in Particular from Metal Pipes - The invention relates to a device for the partial removal of coating from pipes, in particular from metal pipes, having a base body, an accommodation area, for a pipe formed on the base body at least two supporting means, for supporting the pipe arranged on a first side of the accommodation area and a scraper head arranged on an opposite side of the accommodation area, wherein the scraper head has two prismatic scraper edges. The invention furthermore relates to the use of a device according to the invention for the at least partial removal of coating from pipes. | 10-06-2011 |
| 20110302732 | DUAL-CONNECTION RUBBER BALL FOR CLEANING AND DESCALING IN A HEAT EXCHANGE TUBE - A dual-connection rubber ball for cleaning and descaling in a heat exchange tube, which belongs to the field of cleaning and descaling in the heat exchange tube includes two solid rotatable bodies, elastic cleaning and descaling fins and an intermediate elastic connecting body, the elastic cleaning and descaling fins are disposed uniformly in the circumferential direction of the two solid rotatable bodies, the intermediate elastic connecting body is connected to the two solid rotatable bodies respectively at it two ends, the thickness of the fin is 0.6-2 mm, the ratio of height to thickness of the fin is 1.25-4, the intermediate elastic connecting body can be formed as a cylinder shaped body, a sheet shaped body or a compound body thereof, the diameter of the cylinder shaped intermediate elastic connecting body is 1/10 to ½ of the inner diameter of the heat exchange tube. The thickness of the sheet shaped intermediate elastic connecting body is 1/25 to ⅕ of the inner diameter of the heat exchange tube. The difference between the density of the conveyer fluid and the density of the solid rotatable body is not more than 8%. The present invention has the advantages of being effective in cleaning and descaling, less likely to block the heat exchange tube, and having a long service life. | 12-15-2011 |
| 20130019420 | WIPER FOR TRANSLATING RAM - A wiper for a translating ram with recessed features includes a first element conforming to the recessed features of the translating ram; and a second element conforming to the external surface of the translating ram. The first element and second element conform to the cross-section of the translating ram when placed axially adjacent. | 01-24-2013 |
| 20160114363 | PIPE CONDITIONING TOOL - A pipe conditioning tool comprising a drive unit to move the tool along a pipe and a work head rotatable about an axis of the pipe to condition a surface of the pipe, the drive unit includes a frame extending to opposite sides of the pipe, the frame having legs extending radially beyond the work head to provide support for the tool upon removal from said pipe. | 04-28-2016 |
