Abstract: An opto-acoustic gas analyzer has a black body light source, a chopper in the path of the light emitted from the light source for intermittently intercepting the light from the light source, a positive interference filter in the path of the light for filtering out light other than the wavelengths of light absorbed by the gas being analyzed, and an opto-acoustic detector which receives the filtered light and through which the gas to be analyzed is passed. A pressure change detector provided is provided in the opto-acoustic detector for detecting pressure changes in the gas and producing an electric signal corresponding such changes.

Abstract: A combined motor and rotational cell for use in an apparatus for measuring components in a gas colorimeter, smoke meter, etc. by utilizing light absorption or fluorescence. The combined motor and rotational cell has a motor with a plurality of magnetic poles around the periphery of thereof, at least one diametrically extending partition wall extending across the hollow interior for defining at least two compartments in the rotor, and optically transparent windows on the outside of the motor closing the compartments. A plate-shaped chopper is provided on one side of the rotor having a plurality of apertures therein equidistantly spaced around the chopper. A casing surrounds the rotor and supports the rotor shaft in bearings and has a plurality of coils around the inside of the peripheral wall opposed to the magnetic poles on the rotor. Apertures are provided in the opposite end walls of the casing aligned with the compartments in the rotor for passing light through the casing and the rotor.
