Abstract
1,044,371. Acoustic gas analysis. COAL INDUSTRY (PATENTS) Ltd. Oct. 5, 1962 [Oct. 6, 1961; March 19, 1962], Nos. 36017/61 and 10423/62. Heading H4D. An acoustic gas analyser comprises two electro-acoustic transducers acoustically coupled by the gas and electrically coupled via an amplifier the frequency of the resulting resonant oscillations of the system being indicative of the composition of the gas. In accordance with the invention the relationship between the frequency and loop gain of the system is made such, by the use of an electrical filter and by adjustment of the phase shift and/or gain of the amplifier, that modes of resonant oscillation other than the half-wavelength mode (measured in the gas between the two transducers) are prevented from occurring. Details of the constructional features of two embodiments each comprising a pair of electro-acoustic transducers positioned at either end of a gas sample tube a plurality of which may be connected at different respective positions on a gas pipe line system (e.g. a methane drainage gas main) are given with reference to Figs. 2 and 3 (not shown). A transistorized amplifier incorporating the filter and the phase-shift and gain control arrangement is described with reference to Fig. 4 (not shown).
