The surface properties of iron or ferrous alloy are improved by borosiliconizing the surface by contact with a stream of reducing gas containing hydrogen, optionally with an inert gas, to which a gaseous halide or hydride of boron and silicon have been added, either together or sequentially. The tem ...

Emery J Carlson, John N Armor: Production of aerogels on a support. Allied Corporation, December 16, 1986: US04629652 (7 worldwide citation)

A widely applicable and simple technique has been discovered for preparing aerogels in more durable forms. By the exposure of a variety of support structures to a pregel heated to hypercritical conditions, the resulting aerogel is produced and retained on the supporting structure. Thus, the aerogels ...

Emery J Carlson, John N Armor, William J Cunningham, Addison M Smith: Chromia aerogel, method of producing same and fluorination process utilizing same. Allied Signal, Ernest D Buff, Gerhard H Fuchs, Richard C Stewart, March 27, 1990: US04912270 (7 worldwide citation)

Chromium(III) oxide and hydroxide aerogels are produced by the reaction of chromium(VI) oxide with a solvent which is reducing to chromium(VI), such as methanol, heating the solution to hypercritical conditions, and venting the solvent hypercritically. The product aerogels exhibit surface areas abov ...

John N Armor: Direct oximation of ketones. Allied Chemical Corporation, Robert A Harman, August 7, 1979: US04163756 (7 worldwide citation)

Ammonia, oxygen e.g., as air, and a ketone react in contact with a catalyst such as porous, amorphous silica or alumina which may or may not have a coating to form an oxime, at temperatures such as 50.degree.-500.degree. C. The oximes have known utilities, including uses as oxidation inhibitors and ...


Gamini A Vedage, John N Armor: Disproportionation of amines to produce secondary amines. Air Products and Chemicals, Russell L Brewer, William F Marsh, October 22, 1996: US05567847 (6 worldwide citation)

This invention relates to an improvement in a process for the production of amines and particularly secondary amines by the hydrogenation of aliphatic and aromatic nitriles and disproportionation of the resulting primary amine containing feedstock. The improvement resides in the use of a bimetallic ...

Michael E Ford, John N Armor: Decarbonylation of N-vinylformamide copolymers. Air Products and Chemicals, Mark L Rodgers, William F Marsh, July 25, 1995: US05436299 (5 worldwide citation)

Salt-free vinylamine copolymers are formed by heating the corresponding N-vinylformamide copolymer to a temperature from about 75.degree. to 225.degree. C. in non-aqueous media in the presence of a catalyst comprising a Group VIII metal.
