Abstract: A reciprocating lubricator assembly for a die press employs a non-linear travel path and a mechanical advantage to permit the use of an actuator having a very short stroke to move a lubricating nozzle into and out of alignment with the dies, thereby permitting very rapid operation and increasing the press's production rate. The design of the lubricator assembly may depend upon the size of the press. Relatively small presses employing dies on the order of 6" can accommodate a lubricator assembly the nozzle of which is reciprocated by a glide arm assembly which causes the nozzle to move a stroke on the order of 51/2-7" with a 3" actuator stroke. Larger presses having dies on the order of 14" or larger are better suited for accommodating a swing arm assembly the nozzle of which traverses a stroke of 10" or more with an actuator stroke of 3".

Abstract: The invention provides a method for heat treating aluminum-base alloys. The method increases stress corrosion resistance after heating of the alloy to temperatures between 100.degree. C. and 150.degree. C. A dispersion strengthened aluminum-base alloy containing lithium and magnesium is shaped to form an object of substantially final form. The dispersion strengthened aluminum-base alloy is heated to a temperature between 160.degree. C. and 250.degree. C. for at least 3 hours. The heat treated object has increased stress corrosion resistance after exposure to temperatures between 100.degree. C. and 150.degree. C.

Abstract: A nickel-chromium-molybdenum-niobium alloy affords high resistance to aggressive corrosives, including chlorides which cause crevice corrosion and oxidizing acids which promote intergranular corrosion, the alloy also being readily weldable and possessing structural stability at very low as well as elevated temperatures. The alloy consists essentially of, (by weight), 19-23% Cr, 12-15% Mo, 2.25-4% W, 0.65-2% Nb, 2-8% Fe, balance Ni.

Abstract: A homogenizaton heat treatment for enhancing crevice and pitting corrosion resistance minimizes the formation of Mu phase in nickel-base alloys of high combined percentages of chromium, e.g., 19 to 23% and molybdenum, e.g., 14 to 17%, particularly together with tungsten. Also described is an advantageous alloy composition containing less than 2.5% iron, low carbon and a titanium to carbon ratio greater than 1 which is particularly adapted to be effectively treated by the homogenization heat treatment.

Abstract: A heat treatment of alloy 617 generally including 732.degree. C.-927.degree. C. (1350.degree. F.-1700.degree. F.) for about one hour. The resultant discontinuous carbide network in the grain boundaries inhibits stress corrosion crack growth in polythionic acid environments.

Abstract: An austenitic, age-hardenable nickel-iron-chromium alloy exhibiting high-strength, good corrosion and polythionic acid resistance and having a low work hardening rate. The economic alloy is useful for industrial vessels such as heat exchangers, chemical and petrochemical equipment and, more particularly, tubes. The alloy includes about 25-29.5% nickel, about 14.5-17.5% chromium, about 2-3.5% molybdenum, about 2-5.5% copper, about 1-5% titanium plus aluminum, up to about 1.5% manganese, up to about 0.1% cerium, and the balance mostly iron.

Abstract: A process for heat treating certain nickel-chromium-iron alloys is disclosed which involves annealing the alloys over the temperature range of 1750.degree. F. to 2150.degree. F., preferably in a continuous annealing furnace, for short periods of time, such as 30 minutes to 2 hours, the time being sufficient to precipitate carbides at the alloy grain boundaries. The alloys are useful in nuclear reactor environments.

Abstract: Changing the jets of a Holley carburetor is greatly simplified by an L-shaped adapter which permits the jets to face upward. The jets are removed through access holes drilled in the upper wall of the float bowl by a special screwdriver/gripping tool.
