Abstract
THIS is a simple and automatic milk steriliser for domestic use. It is made in three forms; in one, which is intended for use on an ordinary fire, a tube which carries an alarm bell at the top is inserted through the lid of the saucepan. When the desired temperature (85° C.) is reached, a trigger contained in the tube is automatically released, and the bell rings, thus warning the attendant to take thetpan off the fire. In a second form the action is automatic. A saucepan containing the sensitive trigger is placed on a gas stove, and when the proper temperature is reached the release of the trigger causes the supply of gas to be automatically cut off. A third form is arranged for use with a spirit lamp. In each case, the automatic mechanism is actuated through the melting of an easily fusible alloy.
