Patent number: 4888317Abstract: A structure with encapsulated catalyst-agglomerate bodies which are integral to a porous structure is presented. The catalysts may be singly and/or multiply dispersed on and/or throughout a high surface area material and subsequently mixed with batch material prior to firing the structure. This results in a structure wherein encapsulated catalyst-agglomerate bodies in a porous structure exhibit the same catalytic activity as in a break in aged catalyst coated substrate.Type: GrantFiled: July 15, 1988Date of Patent: December 19, 1989Assignee: Corning IncorporatedInventors: Thomas P. DeAngelis, Irwin M. Lachman, Raja R. Wusirika

Patent number: 4876227Abstract: This invention is directed to the production of oxide-boride-silicon nitride ceramics consisting essentially of ceramic bodies of oxide and boride phases which have silicon nitride added to improve the properties of the ceramic body for use as wear material, durable interface material, and cutting tool inserts. The addition of Si.sub.3 N.sub.4 to the oxide-boride body provides a durable ceramic material which provides a range of cutting speeds that may be utilized in both turning and milling operations.Type: GrantFiled: August 24, 1988Date of Patent: October 24, 1989Assignee: Corning IncorporatedInventor: Thomas P.

Patent number: 4443313Abstract: In an electrolytic reduction cell for the production of molten metal, particularly aluminium, by electrolysis of a less dense salt monolayer of ceramic shapes is located on the floor of the cell. Such shapes are formed of a ceramic material, wettable by molten aluminium, but not wettable by the cell electrolyte. The spacing between adjacent shapes and/or the apertures in individual shapes is selected such that interfaced surface forces prevent entry of electrolyte between the shapes. The shapes may be tiles, honeycombs, cylinders, tubes, balls etc. The product metal may be collected in a sump for periodic withdrawal from the cell or withdrawn continuously or at short intervals through a selective filter that permits passage of molten metal, but not of molten cell electrolyte, at low withdrawal rates.Type: GrantFiled: June 23, 1982Date of Patent: April 17, 1984Assignee: Alcan International LimitedInventors: Adam J. Gesing, John McIntyre, Meine Vandermeulen, Edward L. Cambridge, Thomas P. DeAngelis
