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.

| 5364227 | Controllable dental turbine A regulatable dental turbine includes an actuator arrangement which is provided for regulating the speed by varying the amount of an essentially constant volume stream of drive fluid striking a turbine wheel of the dental turbine. The change of the direct... | 11/15/1994 |
| 5066191 | Turbine with control system The turbine (1) has a control and regulating system with a pump (31), the pressure of which changes proportionally to the second power of the flow delivered by the pump or to the second power of the speed (n2) of the turbine (1). The hydraulic ... | 11/19/1991 |
| 4811902 | Superhigh pressure fluid injection apparatus A superhigh pressure fluid injection apparatus causes a fine jet streamline flow of superhigh pressure fluid to make a circular motion by utilizing a part of the supplied high pressure fluid. The apparatus includes an eccentric rotary member (3) for eccen... | 03/14/1989 |
| 4714402 | Mechanism for actuating deflector of Pelton wheel One end of an operating rod is connected to a deflector arm which causes a jet deflector of a Pelton wheel to open or close while the other end of the operating rod carries a spring bearing plate which is disposed in the bore of a cylinder which is movabl... | 12/22/1987 |
| 4355949 | Control system and nozzle for impulse turbines An impulse turbine system (10) includes a rotatably mounted turbine wheel (12) and a speed sensing system (40) to sense the speed of the turbine wheel (12). A flow diversion nozzle (14) normally provides a jet of driving fluid to power the turbine wheel (... | 10/26/1982 |
