Abstract: Described is an improved process for producing chemically treated fillers by using a certain combination of functionalizing and hydrophobizing agents in an aqueous suspension of inorganic oxide having a pH of 2.5 or less and increasing the pH of the suspension after chemically treating the filler.

Abstract: Described is an improved process for producing chemically modified fillers by using a certain combination of functionalizing and hydrophobizing agents in an aqueous suspension of inorganic oxide having a pH of 2.5 or less and increasing the pH of the suspension after chemically treating the filler.

Abstract: Described is an improved process for producing hydrophobic particulate inorganic oxides useful for reinforcing polymeric compositions, e.g., rubber, by using a certain amount of hydrophobizing agents in an aqueous suspension of inorganic oxide having a pH of 2.5 or less and increasing the pH of the suspension after hydrophobizing the filler.

Abstract: A key telephone management controller system enabling telephone customers to control and implement changes to customer key telephone systems served by a telephone switching system. Apparatus and a method interactive with telephone customers records customer-selected key telephone button and line features and controls the telephone switching system to assign the customer-selected button and line features to telephone sets of the customer key telephone system.

Abstract: A flowable, room temperature vulcanizable silicone composition is obtained by mixing 100 parts by weight of hydroxyl endblocked polydiorganosiloxane, 0 to 150 parts by weight of a nonacidic, nonreinforcing filler, 2 to 20 parts by weight of methylvinyldi-(epsilon-caprolactamo)silane and 0.25 to 7 parts by weight of an aminoxysilicon compound having 3 to 10 aminoxy groups per molecule. The composition cures on exposure to moisture to a low modulus silicone elastomer which is useful as a sealant for horizontal joints such as in highways or outdoor patios.

Abstract: Pressure sensitive adhesives which require no cure to develop maximum adhesive properties are obtained from mixtures of (1) from 30 to 70 weight percent of block copolymers of A styrenic monomers and B polydimethylsiloxane in which the styrenic blocks account for from 5 to 25 percent by weight of the total weight of the block copolymer and (2) from 30 to 70 percent by weight based on the total weight of (1) and (2) of a copolymer of Mw.sub.3 SiO.sub..5 and SiO.sub.2 units in which the mol ratio of Me.sub.3 SiO.sub..5 to SiO.sub.2 is from 0.6:1 to 0.9:1. A typical example of (1) is a block copolymer of styrene and dimethylpolysiloxane.

Abstract: Silacyclopentyl-bis-epsilon-caprolactam, ##STR1## is useful as a chain extender for hydroxyl compounds, especially hydroxyl endblocked polydimethylsiloxanes.

Abstract: Curable polyorganosiloxane compositions are obtained from mixtures of a vinyl endblocked polydiorganosiloxane having a viscosity of from 20,000 to 100,000 centipoises, a benzene soluble resin copolymer ofR.sub.3 SiO.sub.1/2 units and SiO.sub.4/2 units,an organopolysiloxane having silicon bonded hydrogen atoms and a platinum catalyst. The cured compositions are useful as pressure sensitive adhesives having high tack, good adhesive strength, and an exceptional resistance to creep, even at elevated temperatures.
