Abstract: Compositions containing an acrylamide functional polydiorganosiloxane, a polydiorganosiloxane having methacryloxyalkyl functionality and silicon-bonded alkoxy functionality, a photoinitiator, and an organic titanate can be improved by using organic peroxides. The improvements are observed in shelf life and pot life of the uncurd composition, and the odor of the cured product. The resulting composition has ternary cure mechanisms with two of these mechanisms being available as shadow cure mechanisms, i.e. cures in areas not exposed to ultraviolet radiation by either exposure to atmospheric moisture or by heating.

Abstract: Mixing into a combination of thermoplastic organic resin and magnetic powder used to make a toner, a silanol methylsiloxane resin readily gives a dry toner powder useful in making photocopies.

Abstract: A high-strength, cold rolled steel sheet product characterized by a rimmed surface and an aluminum killed, columbium-containing core is produced by hot rolling at a finishing temperature above its Ar.sub.3 temperature and coiling at a temperature between 1000.degree. F. and 1200.degree. F., cold rolling between 50% and 90% reduction, batch annealing to recrystallize the coil, and temper rolling between 0.75% and 2.0% temper elongation. The product is non-aging, has a 50,000 p.s.i. minimum yield strength in the temper rolled condition, good formability, and a surface quality equivalent to that of Drawing Quality Rimmed Steel.
