Publication number: 20140209126Abstract: Pigs (10) are propelled forwards by a propulsion fluid in a pipeline (21). The pigs (10) have an upstream end (13), a downstream end (11), and an intermediate section (12). The intermediate section has a variable geometry chamber (16) associated therewith and one or more outwardly extending external pawl teeth (15). The pawl teeth are automatically displaceable outwardly relative to a longitudinal axis (9) in response to a pressure differential between a downstream pressure and an upstream pressure. The pig is configured such that a change in a geometry of the chamber in response to the pressure differential between the downstream pressure and the upstream pressure causes the one or more pawl teeth to automatically displace outwardly when the upstream pressure is less than the downstream pressure. When the pawl teeth are deployed, upstream displacement of the pig is inhibited. Various related systems (5) and methods are also disclosed.Type: ApplicationFiled: August 30, 2012Publication date: July 31, 2014Inventor: Ian Doig

Patent number: 8496471Abstract: Pilot light gas line connector assemblies and methods for cleaning a pilot light orifice are disclosed herein. An exemplary connector assembly for coupling to a pilot light gas line and cleaning a pilot orifice has a first fitting end, a second fitting end, and a passageway therebetween. The first fitting end is adapted to receive a first end of the pilot light gas line and the second fitting end is adapted to receive a valve capable of directing forced air from a forced air source into the second fitting end. Methods of cleaning a pilot orifice of a pilot light system include removing the pilot light gas line from a gas port and coupling the pilot light gas line to a pilot light gas line connector assembly. Then forced air is directed into the connector assembly and through the pilot light gas line, thereby cleaning the pilot orifice.Type: GrantFiled: May 4, 2010Date of Patent: July 30, 2013Inventor: Daniel B. Griffith

Publication number: 20130167732Abstract: When, according to the invention, various hot and cold beverages are made from ingredients in a preparation part (1), the dispensing may take place via an outlet pipe (4) with an outlet head (5), to which the beverage ingredients are supplied, and where they are mixed immediately before or at the same time as the beverages are dispensed. This ensures a high quality, as the dispensed beverages will be fleshly produced with the best possible flavour. The supply channels (16, 16a, 16b) for milk are flushed with water after each dispensing for hygienic reasons.Type: ApplicationFiled: September 7, 2011Publication date: July 4, 2013Applicant: SCANOMAT A/SInventor: Kim Vibe Petersen

Patent number: RE44518Abstract: This application discloses an automated apparatus for scarifying the interior surface of a pipe or other similar elongated passageway. The apparatus includes a vehicle that propels itself down the inside of the pipe. A scarifying assembly is removably secured to the vehicle and uses arms to reach the walls of the pipe. At the end of each arm there is a fluid nozzle assembly equipped with fluid nozzles. The fluid nozzle assembly rotates or oscillates to scarify the pipe surface. The arms and fluid nozzle assembly interchange with other such scarifying assemblies depending on the shape or type of pipe and the desired scarifying technique. The apparatus is tethered to a source of fluid under pressure and a power source, both of which are located off-board the apparatus at a remote location.Type: GrantFiled: May 2, 2007Date of Patent: October 8, 2013Assignee: Mac & Mac Hydrodemolition Inc.Inventors: Gerard MacNeil, David MacNeil, Gordon MacNeil, Vernon Bose
