Patent number: 9888808Abstract: A method of making cookware containing a bonded composite comprising the steps of providing at least two layers of materials by pressurizing and heating wherein the first of the at least two layers of materials has a plurality of spaced-apart bubbles formed on its surface, defining a cooking surface of the cookware, and a second layer of two layers of material is bonded thereto, wherein the bonding between the bubbles and the second material is of a lesser degree than the bonding between the first and second layers of materials in areas intermediate the bubbles, whereby a coefficient of heat conductivity is greater in the intermediate areas than in the bubbles. The method also includes providing a plurality of sets of bonding blank assemblies by solid state processing under pressure and heat.Type: GrantFiled: June 11, 2015Date of Patent: February 13, 2018Assignee: All-Clad Metalcrafters LLCInventors: William A.

Patent number: 9756979Abstract: A device for holding a lid to a pot to permit the pouring of liquid from the pot while retaining a food product within the pot, including a pair of spaced apart hook members attached to opposed top edges of the pot and positioned off-set from a centerline of the pot. The hook members each include a horizontal top flange turned inwardly toward the pot, whereby when the pot is moved to a pouring position, the liquid forces the lid to separate from the pot and the top flanges of the hook members to engage the lid to maintain a predetermined pouring gap between the lid and the pot and also to prevent the lid from sliding forward off the pot due to their off-set positioning from the pot centerline.Type: GrantFiled: October 8, 2012Date of Patent: September 12, 2017Assignee: All-Clad Metalcrafters LLCInventor: William A.
