    Abstract: The concentration of multiple polyatomic gases are determined almost simultaneously by Raman scattering. The gas sample is placed in a sampling cell located in the resonance cavity of a laser and a polarized laser beam having sufficient intensity to produce detectable signals of Raman scattered light is passed through the cell. The scattered light is captured and redirected by means of a reflection mirror located parallel to the axis of the laser beam adjacent to and outside of the cell. Signals of both inelastic Raman scattered light and elastic laser scattered light are collected by a collection lens means opposite the reflection mirror and outside the gas cell. The collection lens is also parallel to the axis of the laser beam. The collected scattered signals are directed onto a laser line rejection filter where the scattered elastic laser signals are filtered out and the inelastic Raman scattered signals are transmitted to come in contact with a rotating filter wheel containing a series of interference filters with each filter being specific to the transmission of one Raman line. The Raman lines passing through the rotating filters are sensed sequentially by a single detector means and amplified and converted into digital electrical pulses which are processed and converted into visual readouts indicative of the concentration of each of the polyatomic molecules in the gas being determined.

    Abstract: Defects in a measurement device are detected in a biochemical analysis apparatus wherein a droplet of liquid sample is applied to an analysis medium containing a reagent, which chemically reacts with a specific constituent in the liquid sample, the analysis medium is then incubated, the optical densities of the analysis medium are determined, and concentration of the specific constituent in the liquid sample is determined from the optical densities of the analysis media thus determined. The method for detecting defects comprises the steps of irradiating light, which has passed through a plurality of interference filters by turns, to a reference density plate, and measuring the amount of light reflected by the reference density plate. Measured values representing the amounts of reflected light, which have thus been measured for the interference filters, are compared with one another. Defects in the measurement device are detected from the results of the comparison.

    Abstract: The Laser Line Identifier (LLI) is a real-time device which can indicate wavelengths of the laser radiations. LLI mainly consists of a beam splitter, narrow bandwidth transmission filters and detectors. The filters and the detectors form a unique pair so that a signal detected at a particular detector can only mean the radiation of a certain wavelength. The detectors are hardwired to a set of indicators such as a set of colored lights or a voice recording so that the wavelength of the radiation is clearly indicated even to a non-technical person.

    Abstract: The object of this invention is a double multichromatic photometer including a single light-source and a single detector, particularly for the determination of chemical and clinical analyses, in which the photometer light comes from a single light-source which radiates along three distinct optical paths that converge onto a single detector; two of the optical paths are the first and the second measuring channels, which are alternatively excluded whereas the third optical path is for reference purposes. An optical collimation assembly and a measurement cuvette are inserted into each of the two measuring optical paths or channels. Within said three optical paths is inserted a rotating drum, said drum holds a number of interference filters, allowing the third reference optical path to pass freely, and inserts one filter at a time into one or the other of the two measuring optical paths. Moreover, a rotating shutter controlled by a motor is also provided for the reference optical path, said shutter coordinately rotates with the filter-bearing drum. An opto-electronic assembly, including printed circuit boards and optical couplers are provided for the selection of filters and the measuring channel.
