Assignee:

Cytec Technology Corp. - Wilmington DE

International Classification:

C08K 534

US Classification:

524100, 524 83, 524 84, 524 92

Abstract:

This invention relates generally to a new class of benzocycle-substituted pyrimidines and triazines and the use thereof to protect coatings, polymers and organic compounds against degradation by environmental forces, inclusive of ultraviolet light, actinic radiation, oxidation, moisture, atmospheric pollutants and combinations thereof. The new class of benzocycle-substituted pyrimidines and triazines comprises a benzocycle attached to the triazine or pyrimidine ring, and preferably an additional aryl ring containing a hydroxyl group, either free or blocked to form a latent stabilizer, ortho- to the point of attachment to the triazine or pyrimidine ring.

Appl. No.:

6/159913

Inventors:

John A. Larson - Easton PA
Robert B. Fischer - Easton PA

Assignee:

Ingersoll-Rand Company - Woodcliff Lake NJ

International Classification:

C22C 3816

US Classification:

75125

Abstract:

A cavitation resistant, low carbon 12% chromium steel alloy utilizing a nominal 1. 5% copper addition which imparts strength by a precipitation reaction. The alloy exhibits a higher strength and hardness for a given carbon content and conversely is less susceptible to casting and welding cracks and stress corrosion cracking.

Assignee:

Ingersoll-Rand Company - Woodcliff Lake NJ

International Classification:

C22C 3812

US Classification:

148 36

Abstract:

A low carbon Martensite transformation induced substructure, with nickel and molybdenum providing solid solution strengthening is obtained in a low chromium-nickel casting steel consisting of less than 0. 06 percent C, 4. 75 to 5. 75 percent Cr, 2. 75 to 3. 50 percent Ni, 0. 45 to 0. 65 percent Mo, less than 1. 0 percent Mn, less than 0. 75 percent Si, 0. 05 to 0. 12 percent Al, and less than 0. 04 percent of each P and S with the remainder essentially Fe with a specific double normalize heat treat and temper in conjunction with controlled chemistry, the resulting material has excellent impact properties. The weldability and foundry handling characteristics are excellent without preheat. It has superior tensile properties and significantly higher impact properties than the present ASTM A 217 Gr. C5 alloy which it can replace.

International Classification:

C01G 5500
C01G 3900
C01G 5100
C01G 5300

US Classification:

423 22

Abstract:

Spent catalysts are extracted for removal of catalytic metals from inert supports by oxidizing subvalent metals in a solution of a ligand which forms a soluble stable complex with the oxidized metal. The ligands are salts of 1,1-dithiolate, dithiocarbimate and dithiocarbamate dianions for extraction in water and of dithiocarbamate monoions for extraction in organic solvents.

US Classification:

148 36

Abstract:

A low carbon Martensite structure is obtained in a low chrome-nickel casting steel consisting of less than 0. 06 percent C, 4. 75 to 5. 75 percent Cr, 2. 75 to 3. 50 percent Ni, 0. 45 to 0. 65 percent Mo, less than 1. 0 percent each of Mn and Si, and less than 0. 04 percent of each P and S with the remainder essentially Fe. The resulting material has excellent weldability and handling characteristics without preheat. It is superior in this regard to the present ASTM A217 Gr 56 alloy which it is intended to replace.
