Inkjet ink compositions comprising modified pigments

Abstract: The present invention relates to an inkjet ink composition comprising a liquid vehicle and a modified pigment, which comprises the reaction product of a non- modified pigment and at least one reagent having the formula H2N-A-Y. The modified pigments themselves, as well as methods for preparing them, are also described.

Conductive polyacetal composition

Abstract: An electrically conductive polyacetal composition having improved toughness and flexibility, as well as good fluidity and processability. The composition includes an oxymethylene polymer, an elastomeric polyurethane, and an electrically conductive carbon black having a lower structure level (DBP absorption) and larger particle size (lower surface area) than conductive carbon blacks heretofore used in these compositions. The composition includes between about 65 and about 85 percent, by weight, of the oxymethylene polymer, between about 10 and about 20 percent, by weight, of the electrically conductive carbon black, and between about 10 and about 20 percent, by weight, of the elastomeric polyurethane. The electrically conductive carbon black has a surface area BET (N2) of between about 40 and about 100 m2/g, and a pore volume, DBP absorption, of between about 150 and about 350 ml/100g. The electrically conductive carbon black used in the present compositions is more easily dispersed in the composition polymers and lessens any increase in melt viscosity during compounding.

Slow Strain-Rate Technique and Its Applications to the Environmental Stress Cracking of Nickel-Base and Cobalt-Base Alloys

Abstract: The slow strain-rate technique (SSRT) was used to investigate the susceptibility of several nickel-base and cobalt-base alloys to environmental stress cracking. This technique was successful in revealing the stress corrosion cracking (SCC) tendency of a given alloy in a specific environment. Yet, the measurable quantities (percent elongation, percent reduction in area, load at failure, and the total time to failure) were not always consistent indicators of the SCC phenomenon nor of its severity. Metallographic examination allowed to quantify the susceptibility to SCC through the measurement of the average "secondary stress corrosion crack" depth. The effects of strain rate, solution temperature, and solution concentration were clearly established using the SSRT. However, the effect of cold work on the susceptibility to hydroxide stress cracking was inconclusive. Also, the SSRT was not able to distinguish the SCC phenomenon from that of a "stress assisted intergranular corrosion" occurring on sensitized material.

Methods of making cesium salts and other alkali metal salts

Abstract: A method of making a cesium salt is described and involves reacting a cesium sulfate containing solution with lime to form 1) a solution containing at least cesium hydroxide and 2) a residue comprising calcium sulfate. The method further involves removing the residue from the solution and converting the cesium hydroxide that is present in the solution to at least one type of cesium salt. The present invention further relates to uses of the cesium salt as well as methods of making cesium hydroxide using lime. Also, methods of making alkali metal salts and alkali metal hydroxides are also described.
