    Abstract: This invention relates to a colorimeter with a light source which through a sample to be investigated illuminates a photoelectric transducer, the output of which is connected to a measuring device for measuring the intensity of the transmitted light. The light source is operated from a supply source which is effective to intermittently energize and de-energize the light source, the de-energized periods of the light source being at least as long as the energized periods.

    Abstract translation: 本发明涉及一种具有光源的色度计，其通过待研究的样品照射光电换能器，光电变换器的输出连接到用于测量透射光强度的测量装置。 光源从供电源操作，其有效地间歇地给光源通电和断电，光源的去激励周期至少与通电时段一样长。

    Abstract: AN ANALYTICAL INSTRUMENT INCLUDING A FLAME SOURCE AND A DETECTION SYSTEM FOR THE QUALITATIVE AND QUANTITATIVE EMISSION OR ABSORPTION ANALYSIS OF A SAMPLE. THE SAMPLE IS ATOMIZED AND MIXED WITH AN APPROPRIATE FUEL GAS, AND THE MIXTURE IS LED THROUGH AN ANGULARLY DISPOSED BURNER BARREL TO A GRID FOR HOLDING THE FLAME. COMPRESSED AIR IS SUPPLIED TO THE ATOMIZER, AND A PORTION OF THE AIR IS DIRECTED TO A VENTURI NOZZLE WHICH IS CONNECTED TO A SUPPLY OF THE FUEL GAS. THE AIR IS EFFECTIVE TO DRAW THE FUEL GAS THROUGH THE VENTURI AND INTO THE ATOMIZER AT A SUBSTANTIALLY CONSTANT RATE IRRESPECTIVE OF PRESSURE FLUCTUATIONS IN A GAS SUPPLY. THE INSTRUMENT ADDITIONALLY INCLUDES A SCREEN AND BAFFLE CONSTRUCTION WITHIN THE ANGULARLY EXTENDING BARREL WHICH IS EFFECTIVE TO DIRECT LARGE DROPLETS OF SAMPLE MATERIAL AWAY FROM THE BARREL INLETS.

    Abstract: A COMBINATION TEACHING AID AND MODULAR INSTRUMENTAL ANALYSIS SYSTEM IN WHICH A PLURALITY OF MODULES ARE PROVIDED, EACH HAVING A SEPARATE FUNCTION, AND IN WHICH THE DIFFERENT MODULES ARE ADAPTED TO BE PLACE TOGETHER IN DIFFERENT COMBINATION TO PROVIDE DIFFERENT OPTICAL ANALYSIS INSTRUMENTS. THE MODULES INCLUDE A LIGHT SOURCE FOR PROVIDING LIGHT, A DETECTOR MODULE FOR RECEIVING LIGHT WHICH HAS BEEN EXPOSED TO A SAMPLE COMPARTMENT MODULE WHICH RECEIVES ONE OR MORE SAMPLES TO BE ANALYZED, AND MAY INCLUDE DISPLAY MEANS IN THE FORM OF A METER OR THE LIKE FOR READING THE OUTPUT OF THE DETECTOR MODULE. THE COMBINATION MAY ALSO INCLUDE A MONOCHROMATOR UNIT FOR PROVIDING SUBSTANTIALLY MONOCHROMATIC LIGHT, AND A FILTER MODULE WHICH IS ADAPTED TO CONTAIN ONE OR MORE FILTERS THROUGH WHICH A LIGHT BEAM MAY BE PASSED FOR OBTAINING A BEAM OF DESIRED FREQUENCY. DIFFERENT ARRANEMENTS OF THE VARIOUS MODULES WILL PRODUCE A SPECTROPHOTOMETER, A FILTER PHOTOMETER, OR A NEPHELOMETER. THE DESCRIBED MODULE UNITS ARE ARRANGED SO THAT AT LEAST SOME OF THEM MAY BE DISPOSED ON A BASE AND OPTICALLY ALIGNED BY MEANS OF COMBINATION ADJUSTING AND CLAMPING MEANS, SO THAT THE UNITS MAY BE THERE AFTER MOVED, OR REPLACED AS DESIRED WITHOUT AFFECTING THE ALINGMENT THEREOF. THE DESCRIBED UNITS ARE CONSTRUCTED AND ARRANGED SO THAT ALL THE SIGNIFICANT OPERATIONAL AND FUNCTIONAL PROPERTIES OF EACH MODULE MAY BE DIRECTLY OBSERVED BY THE STUDENT. THEREFORE, EACH MODULE IS ADAPTED TO PERFORM A MINIMUM NUMBER OF FUNCTIONS, AND THE MODULAR CONCEPT AND THE CONSTRUCTION FEATURES ARE USED AS A TEACHING AID USED TO EMPHASIZE THE RELATION BETWEEN VARIOUS SYSTEMS OF OPTICAL INSTRUMENTAL ANAYLSIS. THE FILTER COMPARTMENT MODULE AND THE SAMPLE COMPARTMENT MODULE INCLUDE HOLDER MEANS FOR HOLDING LIGHT FILTERS OR SAMPLE UNITS, AND THE HOLDER UNIT IS CONSTRUCTED SO AS TO FACILITATE INTERCHANGE OF SAMPLE HOLDERS AND FILTER UNITS, AND TO BE ADAPTED FOR USE WITHOUT CHANGE TO PERFORM DIFFERENT FUNCTIONS IN DIFFERENT INSTRUMENATAL COMBINATIONS.
