| 摘要 | The present invention relates to a method for stabilizing the temperature of an instrument which consists in that the instrument whose temperature has to be stabilized, is brought into contact with a container containing a temperature stabilizing element which presents, in the considered temperature range, at least one transformation point, so that the latent heat of transformation, which produces an elevation of the calorific capacity at the time of the passage through the transformation point, stabilizes the temperature of the instrument. | ||||||
| 权利要求 | 1. Method for stabilizing the temperature of a timepiece to permit it to operate within its normal working temperature range which comprises introducing the timepiece into a container having therein a body of a temperature stabilizing medium which exhibits at least one heat transformation point, whereby the latent heat of transformation absorbed or emitted by said medium at the time of passage through its transformation point produces a rise or fall in the temperature of said timepiece thereby stabilizing it. 2. The method of claim 1 in which the temperature stabilizing medium is selected from the group consisting of caesium, gallium, mercury and water. 3. The method of claim 1 in which the temperature stabilizing medium is composed of two materials exhibiting two different transformation Points whereby said timepiece is stabilized with respect to both rising and falling temperatures. 4. The method of claim 1 in which the temperature stabilizing medium comprises gallium and water. 5. Method for stabilizing the temperature of an instrument to permit it to operate within its normal working temperature range which comprises introducing the instrument into a container having therein a body of a temperature stabilizing medium which exhibits at least one heat transformation point, whereby the latent heat of transformation absorbed or emitted by said medium at the time of passage through its transformation point produces a rise or fall in the temperature of said instrument thereby stabilizing it, said instrument being a timepiece adapted to be carried by an astronaut. |
