Patent number: 4495223Abstract: There is disclosed an improved process for phosphating asbestos fibers by reacting phosphorus chlorides with asbestos fibers in a first reaction vessel heated to a temperature within the range of the boiling temperature of the selected phosphorus chloride at atmospheric pressure and 200.degree. C. above the boiling temperature of said phosphorus chloride, then the phosphated asbestos fibers are cured in a second chamber and purged of any volatile by-product formed during the phosphating step. The products obtained possess reduced haemolytic activity.Type: GrantFiled: February 22, 1984Date of Patent: January 22, 1985Assignee: Societe Nationale de L'AmianteInventors: Jean-Marc Lalancette, Marcel Cossette, Pierre Delvaux

Patent number: 4486254Abstract: This disclosure is directed to a heat-activated patch or repair composition for metal object or surface capable of maintaining its shape at the temperatures to which it is heated to activate and set the composition and ranging from about 250.degree. to about 500.degree. F. comprising a preponderant concentration of a fibrous adhesive containing silicate, soda and asbestos fibrous cement, and lesser concentrations of iron ore and an alumina-containing air set mortar having Pier test of about 600 to about 800 p.s.i. and comprised of alumina, clay and grog (ground-up fired clay). The aforementioned heat-activated patch or repair composition is utilized in a system for repairing such metal object or surface by intimately associating said composition with asbestos cloth, preferably woven asbestos cloth, by applying said composition to one surface of said asbestos cloth and then wrapping the adhesive composition surface of the woven asbestos cloth around the exterior of the metal object or surface to be repaired.Type: GrantFiled: February 3, 1983Date of Patent: December 4, 1984Inventor: Oliver Zinimon
