Abstract: 300,799. Christiani, H. V. de, and Cuminatto, A. Nov. 28. 1927. Self-driving apparatus. - An apparatus designed to utilize the additional rise in temperature which, it is stated, a heated body experiences if, during its rise of temperature, the source of heat is removed, comprises as the heated body a resistance coil 25 traversed bv current led in at terminals 21, 22. The circuit is such that, as shown, when the needle 9 of a temperature indicator touches a contact 7, the circuit of an electromagnet 11 is made which causes pivoted levers 13, 18 to move so that the main circuit heating the resistance 25 is closed at the points 19, 20. The rise in temperature that results, moves the needle 9 down to a contact 8 which breaks the main circuit, and closes the circuits through the points 17 which excites electromagnets 10, the needle moving past the contact 8 owing to the effect mentioned above. As the coil cools the needle moves back to the contact 7 when the action is repeated. The additional heat due to the above effect can thus be utilized. In a modification, the pivoted levers 13, 18 are actuated separately, a bell and lamps being included in the circuit to give notice of the various stages of the process. A clock-work device may be substituted for the temperature-measuring device.
