5614. Fr÷hlich, B. March 15. Acetylene. - T h e tank a has a lower extension b in which is a spring c. The spring forces upwards a carbide container d into a water layer f. The gas, as generated, may pass away through a tap or be allowed to accumulate. The pressure in the latter case forces t h e carbide tank downwards, against the action of the spring, till it is entirely beneath the water layer, and is surrounded by a layer e of an inactive liquid, such as chloroform or carbon bisulphide. On the pressure falling, the carbide container again rises.
