Abstract: 674,750. Meteorological instruments. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 20, 1950 [July 20, 1949], No. 19143/49. Class 97 (iii). [Also in Group XXXVIII] An instrument, e.g. for aircraft, for detecting conditions likely to result in the formation of ice from the atmosphere comprises two heated elements supplied with heat at constant rate, one of which is impinged directly by the air and the other by the air freed from water droplets, and each of said elements has associated therewith means responsive to the temperature thereof. A constant difference may be maintained between the temperatures of the two heated elements in air free from droplets and means may then be provided to respond to such change of this temperature difference due to the presence of water droplets in the air. As shown, the instrument comprises a casing 8, 9 divided internally by a partition 10 into front and rear portions. The front portion contains a heater 13, 14 by which its walls 8, 9 are heated and has a heated element 2 against which air may impinge directly mounted at the front of the portion. The rear portion contains another heated element 7 and is open to the ambient atmosphere at the front and at the rear thereof as by rectangular passageways or openings 17, 18, 19. The cross-sectional configuration of the casing as a whole and the openings 17, 18, 19 to the atmosphere are such that when moved forwardly through the air an aerodynamic action takes.place whereby air is drawn from the front of the rear portion through openings 17, 18 and is replaced by air having passed over surfaces 8, 9 and freed from water entering the rear portion through opening 19 so as to impinge on the heated element 7. The heated element 2 is indirectly heated from an electrical heater element 1, is such that its resistance varies with temperature and backs a thin sheet of material 3 against which the air impinges. The resistance of element 7 also varies with temperature and is electrically heated by an internal heater 6. The elements 2 and 7 may then be connected into the arms of a bridge circuit for indicating the temperature difference or alternatively thermocouples may be employed.
