Patent CA-2377652-C (CA)
Title: A corrugated pipe plant
Inventor: HURLER MICHAEL
IPC: B29C48/13
Filed: 2002-03-20
Granted: 2009-06-23
Abstract: The present invention relates to an apparatus for the manufacture of corrugated pipes from thermoplastic in which mould segment halves, which complement one another in pairs, are guided together in a circuit along a mould path adjacent to an injection head, are moved apart at the end of the mould path and are returned back to its start separately from one another. The apparatus has a mould path device to move the mould segment halves along the mould path and a return conveyor to return the mould segment halves from the end of the mould path back to its start, with the mould path device comprising a machine table having a lower guide and lower drive means for the mould segment halves and a cover frame secured to the machine table having an upper guide and upper drive means for the mould segment halves. The mould path device and the return conveyor form units separated from one another, with a portal robot fixedly anchored to a base plate being provided as the return conveyor and the mould path unit being a mobile unit travelable on the base plate. The upper drive means at the cover frame have driving pinions which can be driven around a vertical axis and which can engage into racks at the upper side of the mould segment halves such that a vertical offset is possible, for example as a consequence of thermal expansion, between the mould segment halves and the driving pinions. Furthermore, a direct cooling system is provided for the better dissipation of heat from the mould segment halves which circulates coolant through coolant passages in the mould segment halves during the movement of the mould segment halves along the mould path.

Title: Improvements to laser welding system
Inventor: PERRY WARREN
IPC: B23K26/42
Filed: 2002-08-29
Granted: 2007-04-03
Abstract: Disclosed herein is a laser welding system having a travel path to carry a first blank and a second blank. An upstream clamp assembly and a downstream clamp assembly are positioned on the travel path and each of the upstream and downstream clamp assemblies are movable to an open position to allow the first blank to pass through the upstream clamp assembly to a first location within the downstream clamp assembly. A laser welding source is directed at a weld location on the travel path between the upstream and downstream clamp assemblies. At least one locating means is operable to locate the first weld edge adjacent the weld location. A first displacement means displaces the first weld edge against the locating means. The downstream clamp assembly is movable from the open position to a closed clamped position to clamp the first blank with the first weld edge adjacent the weld location. The locating means is operable to be withdrawn from the travel path. The upstream clamp assembly is movable from the open position to an intermediate position, which is selected to guide the second blank to pass through the upstream clamp assembly in a substantially coplanar relationship with the first blank so that the second weld edge makes contact with, but not past, the first weld edge. A second displacement means displaces the second blank to a location adjacent the weld location where the second weld edge abuts the first weld edge. The upstream clamp assembly is movable from the intermediate position to a closed clamped position to clamp the second blank and the - the laser welding source is operable to fuse the first and second weld edges blanks together.

Title: Temperature-controlled induction heating of polymeric materials
Inventor: SCHULER PETER
IPC: B29C65/00
Filed: 2001-05-01
Granted: 2008-11-18
Abstract: The present invention provides new polymer induction bonding technology.  Induction heating technologies are utilized to weld, forge, bond or set polymer materials. The invention provides controlled-temperature induction heating of polymeric materials by mixing ferromagnetic particles in the polymer to be heated. Temperature control is obtained by selecting ferromagnetic particles with a specific Curie temperature. The ferromagnetic particles (13,83) will heat up in an induction field, through hysteresis losses, until they reach their Curie temperature. At that point, heat generation through hysteresis loss ceases. This invention is applicable to bonding thermoplastic materials, wherein only the area to be heated has ferromagnetic particles in it; bonding of thermoset composites (17), which have been processed with a layer of thermoplastic material (19) on one side;  curing of thermoset adhesives or composite resins; or consolidating thermoplastic composites.
