Since bristles [330] made from these metals cannot be secured firmly by soldering or epoxy, they are folded over a retaining member [350], or wrapped around the retaining member ... 11/01/07 - 20070251038 - Cleaning bullet A cleaning bullet for use in a pipe or track includes a compressible body. In one embodiment, a sheet draped over the body is engageable with interior walls of the pipe or track to clean small contaminants. In another embodiment, the body is formed from an absorbent material that absorbs ... 09/20/07 - 20070214590 - Pipeline pig A device for travelling along a pipeline having fluid flowing along it comprises means for extracting power from said fluid flow and using that power to move the device along the pipeline against the fluid flow. The device is arranged in a series of coupled modules. ... 08/02/07 - 20070174983 - Apparatus There is described a novel apparatus for use in connection with pipe cleaning and monitoring systems. The apparatus is a suspension system adapted to fit a pipeline pig shaft, the pig being provided with a plurality of wheels. The wheels are concentrically mounted around a biasing means which is operable ... 07/05/07 - 20070151055 - Pipeline pig brush and brush assembly A brush useful in pipeline pigs, for example, in magnetic flux leakage tools or cleaning tools, a method of making the brush and pipeline pig comprising the brush. The brush has a metal bristle holder and a plurality of bristles, the ends of which are held in the bristle holder ... 05/24/07 - 20070113362 - Structured foam pig The present invention relates to a device intended to be passed through a pipeline of variable diameter, propelled by a liquid flowing inside said pipeline. The device has an elongated cylindrical body (2) made of polymer foam, with a number of deep channels (5) equally spaced from each other, coiled ... 09/14/06 - 20060200923 - Hydraulically dynamic mono-pig scraper The invention concerns a pig scraper for cleaning the inside wall of a coating agent conduit. The pig scraper includes a body insertable in the conduit and at least one sealing lip that seals against the inside wall of the conduit and extends parallel to a longitudinal axis of the ... 03/30/06 - 20060064829 - Pipeline pig Vehicle parts of a pipeline pig are connected by a pivotable joint. The joint comprises first and second part-spherical hollow shells joined together, each shell having an aperture therein, said apertures being aligned, said first shell being mounted in a curved recess in said first vehicle part to the pivotable ... 03/02/06 - 20060042033 - Device for moving a pig through a conduit, such as a pipeline A pig towing device is adapted for movement through a conduit having bends and open T intersections. The pig has a front leading cup and a rear trailing cup adapted to seal with the conduit for propelling the device through the conduit. The leading and trailing cups are spaced apart ... 12/29/05 - 20050283930 - Metal brush and method therefor A metal brush useful in pipeline pigs, for example, in magnetic flux leakage tools or cleaning tools, a method of making the brush and pipeline pig comprising the brush. The brush has a metal bristle holder and a plurality of metal bristles, the ends of which are held in the ... 10/20/05 - 20050229342 - Tractors for movement along a pipeline within a fluid flow A tractor comprises a tractor module (10) coupled at opposite ends to a cleaning or inspection module (11) and a power generation module (12), the three modules being arranged in line within a pipeline (14) such that traction elements (15) on the tractor module (10) engage the wall of the ... 10/13/05 - 20050223510 - Hydraulically dynamic mono-pig scraper The invention concerns a pig scraper for cleaning the inside wall of a coating agent conduit. The pig scraper includes a body insertable in the conduit and at least one sealing lip that seals against the inside wall of the conduit and extends parallel to a longitudinal axis of the ... ### FreshPatents.com Support |
