    Abstract: PURPOSE:To miniaturize the apparatus by saving thermostatic chambers, reduce calibration time and improve working efficiency in the measurement of HCl gas, etc., by heating liquid for gas absorption by the use of specific heated double pipes and flowing liquid for calibration from specific spare tanks. CONSTITUTION:In an apparatus of measuring gas densities from the potential difference of the electrodes in a reference chamber 1a and a measuring chamber 1b in a measuring part provided with the chambers 1a and 1b, a heating device 5 composed of only the heat conduction pipes 11 is disposed in a measuring target gar (for example, HCl gas) sampling part 2 from sample gas such as exhaust gas of incineration furnaces, without using any thermostatic chamber. One end of the heating device 5 is connected to the sampling part 2, and the other end forms double pipes 11a, 11b. After gas absorbing liquid L passes the outer pipe 11a, it passes the inside pipe 11b, and the liquid L' having absorbed the gas is sent into the measuring chamber 1b via a flow passage 6 and a heat exchanger 4. In this way, dewing of moisture on the walls of the pipes 11a, 11b is obviated. Calibrating liquid of the volume necessary for substituting the liquid in the flow passage 6 and the measuring chamber 1b is beforehand stored in the tanks 12, 12' and is quickly supplied therefrom for to substitute the absorbing liquid.

    Abstract: PURPOSE:To reduce secular changes of the rate of feed by providing a flexible and non-extensible tape on the inner side of a tube such that it intervenes between an urging roller and the tube so as to absorb temsile force exerted to the tube by the urging roller. CONSTITUTION:A plurality of urging rollers 12 are rotatably provided on the periphery of a rotary disk 11 at a predetermined interval. The tube 13 is held in a tube receptacle 14 in such a manner that it is partly urged by the tube rollers 12. On the inner side of the tube 13, a tape 15 consisting of a metal plate or the like, which is flexible and non-extensible and has high mechanical strength, wear resistance and high durability, is provided. The tape 15 intervenes between the roller 12 and tube 13, and its opposite ends are secured to a frame 16. With this construction, tensile force exerted to the tube 13 is absorbed by the tape 15 with frictional contact with the rollers 12. Thus, secular changes of the rate of feed are less prone, and an excellent constant feed character can be obtained.
