Abstract: An automatic fluid control assembly comprising housing means having an inlet port and outlet port so as to permit the fluid to flow through the housing means between the ports with valve means operatively associated with input port to control the volume of fluid flow through the assembly depending on the position of the valve means relative to the inlet port, and a temperature responsive drive means mounted within the housing means in operative relation to the valve means and adapted to detect temperature changes of the fluid so as to actuate in response to temperature changes within a predetermined range, wherein the valve means is moved to automatically vary the volume of fluid flowing from the outlet port depending upon the temperature of the fluid.

Abstract: Gas-filled discharge tube for use as transient protection, with at least two electrodes separated by a discharge gap and an insulating body which is joined to the electrodes and, jointly with them, forms a discharge chamber. The sealing of the tube occurs at atmospheric pressure and a suitable temperature, in a mixture of a light and a heavy gas suitable for the purpose, after which the tube is enveloped in a suitable heavy gas at atmospheric pressure, while the temperature is adjusted in such a manner that the light gas enclosed in the tube, through diffusion and a partial pressure difference, exits through the insulating body, whereas the heavy gases can only to an insignificant degree diffuse through the insulating body. The gas diffusion brings about a reduction in the total gas pressure inside the tube and the process is interrupted when the desired pressure drop is obtained.
