Abstract
Abstract A cooling device for electron tubes, exploiting the vaporization of a liquid contained in sealed tanks, surrounding the tube anode. The vaporization of the liquid is controlled by a valve associated with the tanks. The blowoff pressure of this valve is equal to the vaporization pressure at the selected temperature of operation.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
132 words
A cooling arrangement for dissipating heat generated by an electron tube in motion with longitudinal and radial accelerations, out of reach, said arrangement comprising: a tight enclosure for a predetermined amount of cooling liquid in thermal contact with said tube, said enclosure comprising a valve opening out into the environment at one of its two ends; means for adjusting the blowoff pressure of said valve as a function of the vaporization pressure of said liquid at a predetermined temperature, a pipe positioned within said enclosure and having an input and an output, said output being tightly connected to said valve at the other end of said valve, said input being disposed such that, for any position of said arrangement during said vaporization, said input is free from any contact with said liquid.
Claim 2
Dependent Claim
132 words
A cooling arrangement for dissipating heat generated by an electron tube in motion with longitudinal and radial accelerations, out of reach, said arrangement comprising: a tight enclosure for a predetermined amount of cooling liquid in thermal contact with said tube, said enclosure comprising a valve opening out into the environment at one of its two ends; means for adjusting the blowoff pressure of said valve as a function of the vaporization pressure of said liquid at a predetermined temperature, a pipe positioned within said enclosure and having an input and an output, said output being tightly connected to said valve at the other end of said valve, said input being disposed such that, for any position of said arrangement during said vaporization, said input is free from any contact with said liquid.
Claim 3
Dependent Claim
41 words
A cooling arrangement as claimed in claim 1, wherein said valve is obturated at said end opening out into the environment by a cap sealed with a sealing material, the melting point of said sealing material being below said predetermined temperature.
