Patent number: 6802191Abstract: The doped silica core region of a core rod for an optical fiber preform is protected against unwanted fluorine doping during fluorine doping of the outer silica layer by selectively consolidating the core region prior to fluorine doping. Due to dopants in the core region, the soot in the core region consolidates before the soot in the outer undoped region. This inherent property allows the entire core rod to be heated prior to fluorine doping resulting in selective partial consolidation and preventing fluorine doping of the doped center core region. The process time required may be reduced by using incremental fluorine doping. In the incremental doping process the doping step is separated into a deposit step, where “excess” fluorine is deposited on the silica particles, and a drive-in step where atomic fluorine is distributed into the silica particles. The drive-in step is conveniently combined with the sintering or consolidation step to further enhance the efficiency of the doping process.Type: GrantFiled: April 19, 2001Date of Patent: October 12, 2004Assignee: Lucent Technologies Inc.Inventors: Yoram De Hazan, John Burnette MacChesney, Eric M.

Patent number: 6802196Abstract: A method of forming a bottle-shaped or other contoured metal container by subjecting a hollow metal preform having a closed end to internal fluid pressure to cause the preform to expand against the wall of a die cavity defining the desired shape, and advancing a punch by means of a backing ram into the die cavity to displace and deform the closed end of the preform either before or after expansion begins but before it is complete. The pressure-subjecting step is performed by simultaneously subjecting the preform in the die cavity to independently controllable internal and external positive fluid pressures and varying the difference between them to control strain rate. Apparatus for performing the method includes a split die with plural split inserts disposed in tandem to define the die cavity wall and heaters respectively inserted within the preform and arranged to heat the backing ram.Type: GrantFiled: October 31, 2002Date of Patent: October 12, 2004Assignee: Alcan International LimitedInventors: Kevin Gong, Peter Hamstra, Stuart MacEwen, Robert Mallory, James D.

Patent number: 6802197Abstract: A process for shaping a high strength container, particularly an aerosol container and a container obtained through such process. Generally, aerosol containers made of aluminum or tin are obtained by conventional embedding processes from sheet disks and have cylindrical bodies with upper tapering finishing at a curl for fixing a valve cover and are closed by convex and profiled cross section bottoms, for forming a support region for upstanding the container. The bottom of such containers is obtained before tapering by means of a blow or front shock once the cylindrical body having planar circular base is shaped, this impact causing undesirable stresses on the body side wall and material accumulation at the annular region joining with this wall since the bottom thickness is not uniform.Type: GrantFiled: January 8, 2003Date of Patent: October 12, 2004Inventor: MarĂa Eugenia Barrera
