    • A radiosonde is conformable for use either as a disposable sonde in which the device will ascend vertically to a predetermined altitude and when the balloon from which it is suspended bursts at a maximum altitude the sonde will automatically flip over and autogyrate at a reduced rate of descent back to earth; or may be used as a tethered radiosonde in which it is suspended from a tethered balloon in such a way as to be freely rotatable about a substantially horizontal axis. In either version, the sonde is characterized by a generally helicoidal propeller construction having thermistor-receiving end tips and whereby the propellers will impart sufficient spin or rotation to the sonde as to cause the desired degree of aspiration to provide accurate wet bulb psychometric measurements; and further the propeller construction is such as to permit freefall at a reduced controlled rate of speed without the assistance of a parachute.

    • An instrument for indicating wind chill temperature has a temperature responsive means producing an indication of temperature and a wind velocity responsive means. Means operatively couples the wind velocity responsive means and the temperature responsive means for altering the indication of temperature produced by the temperature responsive means in accordance with wind velocity. The invention may utilize, e.g., a thermistor, a liquid column thermometer, or a bimetallic element as the temperature responsive means. The indication of temperature may be modified to give the wind chill temperature by a piezoelectric element, a heat transfer surface receiving a predetermined quantity of heat, or a member applying wind force to modify force produced by the bimetallic element, respectively.

    • A wet bulb thermometer. A temperature sensor which can function in a moist environment is placed in such a location that it will be within the mist of water produced by a nozzle when pressurized water is supplied to the nozzle. Preferably, the temperature sensor is placed somewhat below the nozzle to account for the effect of gravity upon the mist of water. Also, preferably, the temperature sensor produces an electrical signal that is indicative of temperature and that can be read by a computer. Accuracy of the determination of the wet-bulb temperature of the air is assured by the redundancy of this device. Evaporation from droplets in the mist assure that the temperature of the air within the mist is at the wet-bulb temperature as, independently, does the evaporation from the film of water which forms on the surface of the temperature sensor. Avoiding confining the spray and conducting liquid water from a reservoir to the temperature sensor eliminates potential external sources of heat which could prevent an accurate determination of the wet-bulb temperature.
    • 一个湿球温度计 能够在潮湿环境中起作用的温度传感器被放置在这样一个位置,当加压水被供应到喷嘴时,其将被喷嘴产生的水雾中。 优选地,将温度传感器放置在喷嘴稍微低于喷嘴处,以解释重力对水雾的影响。 此外,优选地,温度传感器产生指示温度并且可以由计算机读取的电信号。 通过该装置的冗余来确定空气湿球温度的确定精度。 从雾中的液滴蒸发确保雾中空气的温度处于湿球温度,独立地是从温度传感器表面上形成的水膜蒸发。 避免限制喷雾并将液体水从储存器传导到温度传感器消除了潜在的外部热源,这可能阻止湿球温度的准确测定。

    • A method for determining the relative humidity in an interior space without using a special humidity sensor, the method including passing a flow of air of known temperature and humidity through the cooling coil of a known air conditioning system for a pre-determined period of time. The temperature of the air exiting from the cooling coil after the pre-determined period of time is measured. A reference temperature differential is determined by subtracting the exiting temperature from the known temperature of the entering air. A flow of air for which it is desired to know the relative humidity is then passed through the cooling coil for the same pre-determined period of time. The temperature of the air entering the cooling coil and exiting from the cooling coil at the end of this pre-determined period of time is determined. The exit temperature is subtracted from the entering temperature to provide the temperature differential for the air of unknown relative humidity. The reference temperature differential is then compared to the calculated temperature differential. If the temperature differential is smaller than the reference temperature differential the air is then known to be more humid than the known relative humidity. If the temperature differential is the same, the relative humidity is the same, and, if the temperature differential is greater the air is less humid than the known relative humidity.
