| 摘要 | 1. An underwater vehicle including apparatus for generating steam for propelling same, comprising; A. A CLOSED THIN WALL CONTAINER HAVING A VOID SPACE AT ITS UPPER END, B. A MELTABLE SALT MIXTURE FILLING SAID CONTAINER BELOW SAID SPACE, SAID MIXTURE HAVING SUBSTANTIALLY ZERO COEFFICIENT OF EXPANSION AT ITS SOLIDIFYING TEMPERATURE, THE SOLIDIFYING TEMPERATURE BEING IN EXCESS OF 212* F, c. the outside of said container being in contact with and subjected to water at ambient pressure, D. MEANS FOR PRESSURIZING SAID SPACE TO AMBIENT WATER PRESSURE WHEREBY THE SALT MIXTURE, WHEN MELTED, SUBJECTS THE INSIDE OF SAID CONTAINER TO AMBIENT WATER PRESSURE, E. A STEAM GENERATING COIL DISPOSED WITHIN SAID SALT MIXTURE HAVING A WATER INLET AT ITS LOWER END AND A STEAM OUTLET AT ITS UPPER END ADAPTED TO EXTRACT HEAT FROM THE SALT MIXTURE AND CAUSE IT TO SOLIDIFY, FIRST AT THE BOTTOM OF THE CONTAINER, AND THEREAFTER IN SUCCEEDING LAYERS THEREABOVE, AND F. A SOURCE OF SUPERHEATED STEAM FOR MELTING SAID SALT MIXTURE DISPOSED AT THE SURFACE OF THE WATER AND MEANS FOR CONNECTING SAID COIL TO SAME. | ||||||
| 权利要求 | 1. AN UNDERWATER VEHICLE INCLUDING APPARATUS FOR GENERATING STEAM FOR PROPELLING SAME, COMPRISING; A. A CLOSED THIN WALL CONTAINER HAVING A VOID SPACE AT ITS UPPER END, B. A MELTABLE SALT MIXTURE FILLING SAID CONTAINER BELOW SAID SPACE, SAID MIXTURE HAVING SUBSTANTIALLY ZERO COEFFICIENT OF EXPANSION AT ITS SOLIDIFYING TEMPERATURE, THE SOLIDIFYING TEMPERATURE BEING IN EXCESS OF 212*F, C. THE OUTSIDE OF SAID CONTAINER BEING IN CONTACT WITH AND SUBJECTED TO WATER AT AMBIENT PRESSURE, D. MEANS FOR PRESSURIZING SAID SPACE TO AMBIENT WATER PRESURE WHEREBY THE SALT MIXTURE, WHEN MELTED, SUBJECTS THE INSIDE OF SAID CONTAINER TO AMBIENT WATER PRESSURE, E. A STEAM GENERATING COIL DISPOSED WITHIN SAID MIXTURE HAVING A WATER INLET AT ITS LOWER END AND A STEAM OUTLET AT ITS UPPER END ADAPTED TO EXTRACT HEAT FROM THE SALT MIXTURE AND CAUSE IT TO SOLIDIFY, FIRST AT THE BOTTOM OF THE CONTAINER, AND THEREAFTER IN SUCCEEDING LAYERS THEREABOVE, AND F. A SOURCE OF SUPERHEATED STEAM FOR MELTING SAID SALT MIXTURE DISPOSED AT THE SURFACE OF THE WATER AND MEANS FOR CONNECTING SAID COIL TO SAME. 2. Apparatus in accordance with claim 1, including porous heat insulation surrounding said container, and means surrounding the heat insulation for preventing sea water from penetrating the insulation. 3. Apparatus in accordance with claim 1 wherein said means for pressurizing said space comprises a conduit having one end communicating with ambient water and its other end communicating with said space, an intermediate portion being in heat exchange relation with said salt mixture and adapted to generate steam from ambient water for pressurizing said space to ambient water pressure. 4. Apparatus in accordance with claim 3 including a flexible wall within said space, one side of said wall being in contact with the entire upper surface of the salt mixture, the other side being pressurized to ambient pressure through said conduit, whereby entry of the salt mixture into said tube is prevented. |
