"To place a man in a multi-stage rocket and project him into the controlling gravitational field of the moon where the passengers can make scientific observations, perhaps land alive, and then return to earth--all that constitutes a wild dream worthy of Jules Verne. I am bold enough to say that such a man-made voyage will never occur regardless of all future advances."
Lee deForest, American radio pioneer ; 1957

| 5547487 | Amorphous metal alloy and method of producing same A process is described for producing amorphous metal alloys wherein impure ferrophosphorus slag, a by-product from a phosphorus-producing electric furnace, is used to supply phosphorus, chromium, vanadium and iron values to such alloys by mixing it with i... | 08/20/1996 |
| 5518518 | Amorphous metal alloy and method of producing same A process is described for producing amorphous metal alloys wherein impure ferrophosphorus slag, a by-product from a phosphorus-producing electric furnace, is used to supply phosphorus, chromium, vanadium and iron values to such alloys by treating the fer... | 05/21/1996 |
| 5425800 | Recovery of precious metal values from refractory ores A hydrometallurgical process is described for recovery of precious metals from ores refractory to treatment by lixiviating agents by crushing the ore to no finer than a nominal 1/4 inch size, treating the ore with about 100% to about 300% of the stoichiom... | 06/20/1995 |
| 5364605 | Recovery of cyanide from precious metal tailings Process for recovering cyanide values from a mill tailings stream remaining after gold and silver have been leached from an ore, by treating the tailings stream containing both ore insolubles and remaining cyanide leachant, without a preliminary filtratio... | 11/15/1994 |
| 5283054 | Process for producing sodium salts from brines of sodium ores A process for producing valuable sodium-based chemicals from a brine containing sodium carbonate and sodium bicarbonate, such as those containing from about 8% to about 20% total alkali obtained by contacting water with an underground trona formation by h... | 02/01/1994 |
| 5262134 | Process for producing sodium salts from brines of sodium ores A process is described for producing sodium-based chemicals from a brine containing sodium carbonate and sodium bicarbonate by heating the brine to evaporate water and drive off carbon dioxide and obtain a solution that will crystallize sodium sesquicarbo... | 11/16/1993 |
| 5238664 | Soda ash production Process for disposing of insoluble tailings that remain when solubilizing uncalcined or calcined trona in the process of producing soda ash, in which the tailings are slurried with water or waste solutions of sodium carbonate and/or sodium bicarbonate, ad... | 08/24/1993 |
| 5232620 | Sodium tripolyphosphate composition and method of producing it A granular STPP suitable for detergent compositions which is non-caking in non-agitated water is produced by wetting anhydrous phase II STPP granules and drying the granules to remove free water. The resulting granules, when incorporated in detergent comp... | 08/03/1993 |
