Title: Heated die lips system
Inventor: BENTIVOGLIO ALFREDO
IPC: B29C48/10
Filed: 1997-05-06
Granted: 2001-06-05
Abstract: This invention of Heated Die Lips System is specifically designed for use in Film Extrusion Dies. Use of such a system allows Film Extruders to be run at higher production rates with narrower die gaps, while eliminating the melt fracture properties. This Heated Die Lips System, is installed in the final die land area of the extrusion die, on each side of the die gap. It applies direct heat to the polymer melt as it exits the die lips, and reduces the melt viscosity. Thus the 'Critical shear stress' value of the melt is reduced. This results in postponement of the melt fracture property of the film and higher production rates are achieved without melt fracture. Furthermore, this system has been designed so as to insulate it from the main block of the die, minimizing heat dissipation and providing an enclosed system for uniform heating of the die lips.

Patent CA-2224338-C (CA)
Inventor: CAMPBELL SCOTT THOMAS
IPC: C22C1/08
Filed: 1997-12-10
Granted: 2001-05-01
Abstract: The method of the invention produces nickel structures from nickel-coated polymer substrates. The nickel-coated polymer substrate has a nickel outer layer and initially has a temperature where the outer nickel layer lacks burst openings. Rapidly exposing the nickel-coated polymer substrate to a temperature of at least about 600°C thermally decomposes the polymer substrate and bursts holes through the outer nickel layer. The gases resulting from the thermally decomposed polymer substrate escape through the holes through the outer nickel layer to leave a nickel structure. Finally, annealing the nickel structure increases strength of the nickel structure to produce a ductile foam product.
