Did You Know...
...that Charles Goodyear performed some of his experiments on rubber while in debtor's prison? He was there so often he referred to it as his "hotel". Chronically in debt because of poor business sense and ill health, Goodyear depended on the generosity of friends and family. Even after he unlocked the secret to vulcanizing rubber, he was unable to improve his financial situation. When he died, his estate was $200,000 in debt.

| 6813533 | Method for simulation of laser material deposition A method for simulation of laser free form fabrication of parts and laser cladding with metal powder or wire includes absorption of laser beam at the surface exposed to metal powder particle jet, enthalpy influx into the part surface due to powder injection, 3D tran... | 11/02/2004 |
| 6493411 | Method for producing formed bodies of high temperature superconductors having high critical currents Thermal neutron irradiation of superconducting body compositions into which Li or B has been incorporated as a unit cell external or internal dopant introduces by the nuclear reaction of the dopant pinning centers which substantially improve the critical ... | 12/10/2002 |
| 5199999 | Ion implantation in metal alloys A method for ion implantation of relatively high concentrations of alloying elements into a metal target without sputtering the target, in which the target is precoated with a layer of preselected thickness of a light, low sputtering yield element such as... | 04/06/1993 |
| 4746373 | Method of manufacturing compound superconductors A powder having a predetermined composition is filled in a tube. The tube is drawn to obtain a wire and the wire is rolled to obtain a tape-like starting body. Then, a laser beam is irradiated on the part of the tape to heat and melt the part of the tape.... | 05/24/1988 |
| 4729801 | Process for producing superconducting compound tape or wire material by electron beam irradiation A process for producing a superconducting compound tape or wire material, which comprises irradiating electron beams at an acceleration voltage of 5 to 150 KV on a starting tape or wire material consisting essentially of constituent elements of a supercon... | 03/08/1988 |
