B is a vessel supplying the liquid to be raised to thecistern C by means of compressed air supplied by thepipe T;i. On the vertical limb of this pipe, within thevessel A, is a float X, which closes the pipe T3, unless it isbuoyed up by liquid, and when raised by the liquid whichenters the vessel A closes the inlet from the pipe T2. Theaction is as follows : When the vessel A is being filled by. Self-Acting Apparatus for RaisingCompressed Air. LlQtin BY liquid from the pipe T2, air escapes by T, until the floatX closing Tj and T2 opens T3. Compressed air nowenters A, and forces the liquid up the pipe T until A isemptied of liquid, and air escapes up T, relieving thepressure in A, whereupon the float X drops, closing T3 andopening T, and T2; and the action is repeated.—J.

The object of this invention is to provide means by which— 1. The temperature indicated by the thermometer maybe read off directly. 2. This indication may be registered at a distant room orstation. 3. The thermometer may be adjusted for any temperatureso that a rise or fall of the mercury of 1°—2° C. alsomay be indicated at a distant station. The details of the invention cannot be described withoutr
