Abstract: A highly active and selective zeolitic reforming catalyst comprises a type L zeolite containing platinum metal and at least one promoter selected from iron, cobalt, titanium and the rare earth metals, the catalyst having a platinum to promoter metal mole ratio of less than 10:1. In one embodiment a type L zeolite is formed by combining an aqueous solution of potassium hydroxide, aluminum hydroxide, and ferric nitrate with an aqueous solution of silica to form a thickening gel in a mother liquor; heating the thickening gel to form a type L zeolite; cooling the gel containing the type L zeolite; decanting the mother liquor from the gel; filtering the type L zeolite from the gel; washing the filtered type L zeolite so that the pH of the wash is about 10.5 and drying the washed type L zeolite. The catalyst is formed by adding platinum to the dried type Lzeolite by porefill impregnation with an aqueous solution of Pt(NH 3 ) 4 (NO 3 ) 2  to form a catalyst; drying the catalyst and then calcining the dried catalyst.

Abstract: The guiding layers of optical waveguides are formed of arsenosilicate glass (ASG). By varying the arsenic content from 2 to 13 mole per cent it is possible to vary the refractive index in the range 1.45 to 1.53. Pure silica or less heavily doped ASG can be used for the cladding layers. The ASG is preferably formed as the result of a heterogeneous reaction between silane and oxygen in the presence of arsine. Such a reaction can be carried out at temperatures down to 390°C, allowing the ASG to be used on substrates of III-V compounds.

Abstract: The present invention resides in certain at least partially neutralized carboxylated acrylic polymers that are active dispersants for inorganic and metallic powders in aqueous vehicles. These carboxylated acrylic polymers are at least partially neutralized  with quaternary organic ammonium hydroxides. 
     In one embodiment, such a neutralized carboxylated acrylic polymer comprises a water-soluble polymer having an acrylic backbone and carboxyl groups disposed at spaced locations along the backbone. This polymer is at least partially neutralized with a water-soluble quaternary organic ammonium hydroxide that neutralizes at least some of the carboxyl groups. The neutralized polymer is useful in dispersing in an aqueous medium a powder that can release into the aqueous medium one or more multivalent metal cations. The neutralized polymer is stable in solution against precipitation as a metal-polymer complex, at a concentration in the aqueous medium of multivalent cation released from said powder into the aqueous medium, and a concentration of dispersant polymer sufficient to effect dispersion of the inorganic powder. 
     The invention further resides in the use of such polymeric materials as dispersants, in aqueous formulations and compositions containing them, and in shapes such as green bodies made from such compositions.
