Claims (4)

Patent claims:
I. clock with isotope source, thereby indicates that the isotope source (6) in a radiation density, evacuated, from a shell (4) and a firmly connected to it Lid (5) existing capsule is housed, and that over an opposite impact or pressure sensitive insulation bushing (7, 21) through a capsule wall (5) a protective plate (8, JS) is arranged, which is designed as an intermediate floor is. 2. Clock according to claim I, characterized in that the shell (4) is part of the bottom of the watch case forms. 3. Clock according to claim I ₇
shows that the shell (12)
Clock case forms. 4 clock according to claim 1, characterized thereby gekenden bottom of a The watch according to F i g, I has an annular central part of the case 1, with which a threaded ring is screwed 11, which is part of the housing bottom forms. The threaded ring 11 has an outwardly projecting flange 23 which against the seal 3 is applied. The watch glass is not shown, as is the actual movement. The clock has a source of nuclear isotopic energy. With this type of energy source, the radioactive radiation is converted directly into electrical energy. It has a tight capsule that at the same time forms a shield so that any harmful radioactive radiation to the outside is prevented. The isotope source has according to FIG. 1 has a capsule formed by a shell 4 and a lid 5 is, wherein the cover 5 is pressed or soldered into the shell 4 in a sealing manner. In uem between shell 4 and cover 5 formed cavity are located active elements of the source, which are not shows that the protective plate (8, 15) is shown with the ao NEN and generally denoted by 6. With V / nnd of the shell (4, 12) is connected. 7 is a glass or crystal bushing insulation denotes that after melting an opening evacuating the cavity of the capsule 4.5. The bushing insulation 7 is also connected tightly to the cover 5. One above the isolation 7 attached protective plate 8 is in any suitable manner over a shoulder of the wall of the Shell 4 attached. This protective plate 8 has an opening 9. by soft, for example, the axis The present invention relates to an isotope source clock. The purpose of such a clock is to realize an electrically operated movement whose voltage equilibrium, so the battery, practically an unlimited one Has lifetime. I> crartiüc clocks, especially such chipming sources. are known, like this from the »Schweizer Uhr ", No. 14 of July 15, 1957, p. 9, where a battery is described whose active ma- 30 of a wheel of the clockwork can pass. the Plate8 is used for the isolation? mechanically closed protect, and it forms an intermediate floor Conductor 21 connects the active part 6 of the power source with the movement of the electrically operated clock. This lerial consists of promethium, which is coated with phosphorus 35 conductor is melted in insulation 7 over welmisch! and in a transpaiciHc plastic mass rather he by an isolacingcbcttct inserted into the plate 8 will. The electrical energy is generated when the tube 22 is passed through. The isolation 7 with in that the emitted eleclions, the phosphorus forms an insulation layer on the conductor 21 or to shine, whereupon this light in an insulation bushing of the isotope source attached outside of the plastic compound containing silicon capsule 40. The insulation bushing hlekiriKKniluss triggers. This ar! of energy conversion is, however, very important could never be made of plastic, but it is in every case there is a sensitive part that cannot withstand blows or pressure. That makes a special one Protection by plate 8 required The Sdiale4, which is part of the capsule of the energy source forms, is arranged in the ring 11 and forms part of the bottom of the watch case, during the Ring Il forms the other IViI of the soil. In the second embodiment according to FIG. 2 borrowed and \ hastily economical. Hs is the object of the present invention, a To create clockwork, the isotope battery achieves good efficiency and is economical.
