With this device, when the temperature of the room tails, current, is switched on. ami when Hie temperaturo tiscs abovG a coi’tain point the cuiront is' switched off. A similar control has now been applied to gas fires ami Violators through the ingenuity of a British enginein'. He has devised -a regulating valve which contains « /'"Psmo filled with a volatile Imiiid. Waen the (einpe.ruture of the room rises the liquid expands and presses on a diaphragm, which consequently rises and closes the valve. Similarly, when the temperature falls the pressure of tho vapour is reduced the diaphragm is released, and the gas flows fi'eolv. Bv means ot a simple pointer this little valve can ho adjusted to operate at any desired temperature. A by-pass is fitted in order to prevent the How of gas being absolutely Hopped when the valve closes 51, , 1 1’” |ar appliance has been devised by the same, inventor for controlling the temperature of ea=-heated ovens for domestic or industrial uses. . It is expected that the adoption of this valve will be of ndvnntaire not only in industrial processes, but also with the domes ic oven in assisting the cook to use the oven economically.
