  • Inertia friction weld of superalloy with enhanced post weld heat treatment
    Patent number: 9175373
    Abstract: A method of inertia friction welding a superalloy substrate, the method including: rotating and forcing a deposit material (110) against the superalloy substrate (100); plastically deforming at least one of the deposit material (110) and the superalloy substrate (100) to form a weld joining the deposit material (110) to the superalloy substrate (100), thereby forming an assembly; and heat-treating the assembly. Heat-treating includes: a post-weld intermediate stress-relief (ISR) treatment; a solutionizing treatment; and a precipitation hardening heat treatment.
    Type: Grant

  • Manufacturing automation system for nuclear fuel rod production
    Patent number: 4687605
    Abstract: An automated fuel rod production system includes a radioactive powder fabrication and processing stage, a pellet fabrication stage, a pellet processing stage, a tube preparation stage and a fuel rod fabrication and inspection stage, all of which provide a continuous (paced) mode of operation from the conversion of a radioactive gas to powder, through the fabrication of the powder into pellets, to completion of the assembly of the fuel rods. Extra capacity is designed into the system at critical points in the powder processing and pellet fabrication and processing stages to facilitate the continuous, paced mode of operation.

  • Curable organopolysiloxane compositions containing titanium esters
    Patent number: 4111890
    Abstract: An organopolysiloxane composition which is stable under anhydrous conditions, but when exposed to atmospheric moisture cures to an elastomeric solid comprising (1) a hydrocarbonoxy terminated linear organopolysiloxane having at least two hydrocarbonoxy groups per molecule, (2) an organosilicon compound or partial hydrolyzates thereof containing at least two hydrocarbonoxy groups and (3) a titanium ester or partial hydrolyzates thereof in which the hydrocarbonoxy groups linked to the organopolysiloxane, organosilicon compound and the titanium ester groups are the same.
