X-ray beam intensity responsive sequential spectrometer

Claim 1

A SPECTROMETER OF THE SEQUENTIAL MEASUREMENT TYPE WHEREIN THE INTENSITIES OF A NUMBER OF PRESELECTED PARTS OF THE SPECTRUM OF A SAMPLE ARE MEASURED SEQUENTIALLY RELATIVE TO THE INTENSITY OF A BEAM OF PRIMARY RADIATION COMPRISING A RADIATION SOURCE PROVIDING SAID BEAM OF PRIMARY RADIATION HAVING A FIRST PART OF SAID BEAM OF PRIMARY RADIATION DIRECTED ONTO SAID SAMPLE FOR EXCITING SPECTRAL EMISSION OF SECONDARY RADIATION FROM SAID SAMPLE, COLLIMATING MEANS FOR COLLIMATING SAID SECONDARY RADIATION, ANALYZING MEANS FOR SPATIALLY DEFINING THE PARTS OF SAID SPECTRUM OF SECONDARY RADIATION, A SECONDARY RADIATION DETECTOR FOR MEASURING THE INTENSITY OF SAID SECONDARY RADIATION INCIDENT THEREUPON, MOTOR MEANS FOR POSITIONING SAID SECONDARY RADIATION DETECTOR AT SAID SPATIALLY DEFINED SPECTRAL PARTS, SWITCH MEANS FOR ENERGIZING SAID MOTOR MEANS, A PRIMARY RADIATION DETECTOR FOR MEASURING THE INTENSITY OF A SECOND PART OF SAID BEAM OF PRIMARY RADIATION, AN INTEGRATING COUNTER MEANS OPERATED BY SAID PRIMARY RADIATION DETECTOR, AN INTEGRATING COUNTER MEANS OPERATED BY SAID SECONDARY RADIATION DETECTOR, SIGNAL EMITTING MEANS OPERABLE BY SAID FIRSTMENTIONED INTEGRATING COUNTER MEANS UPON SAID FIRSTMENTIONED INTEGRATING COUNTER MEANS REACHING AN ADJUSTABLE PREDETERMINED TOTAL COUNT SO THAT SAID EMITTED SIGNAL ARRESTS SAID SECOND-MENTIONED INTEGRATING COUNTER MEANS, THE COUNT OF THE SECOND-MENTIONED INTEGRATING COUNTER MEANS PROVIDING A MEASURE OF THE INTENSITY OF THE PART OF SAID SPECTRUM BEING MEASURED RELATIVE TO THE INTENSITY OF THE PRIMARY BEAM INDEPENDENT OF THE INTENSITY OF THE PRIMARY BEAM, THE SPECTROMETER FURTHER HAVING AT LEAST TWO MULTIPLE-POSITION SELECTOR SWITCHES SET CORRESPONDINGLY TO THE POSITION OF SAID SECONDARY RADIATION DETECTOR, ONE OF SAID SELECTOR SWITCHES BEING SET CORRESPONDINGLY TO MAJOR POSITION SETTINGS OF SAID DETECTOR AND THE SECOND SAID SELECTOR SWITCH BEING SET CORRESPONDINGLY TO MINOR POSITION SETTINGS COMPRISING EACH SAID MAJOR POSITION SETTING A PLURALITY OF PRESET SWITCHES ARRANGED AS AT LEAST TWO SWITCH GROUPS, EACH SAID GROUP COMPRISING A NUMBER OF SWITCHES EQUAL TO THE SAID NUMBER OF PRESELECTED SPECTRUM PARTS, EACH SAID PRESET SWITCH BEING SETTABLE TO PRESELECT ONE POSITION OF AN ASSOCIATED ONE OF SAID SELECTOR SWITCHES, MEANS ACTUATED WHEN SAID SELECTOR SWITCHES ARE TOGETHER SET TO THE POSITIONS PRESELECTED BY THE ASSOCIATED SAID PRESET SWITCHES FOR DEENERGIZING SAID MOTOR MEANS, AND SEQUENTIAL SWITCH MEANS COMPRISING AT LEAST TWO MULTIPLE-POSITION SELECTOR SWITCHES RESET AFTER MEASUREMENT OF SECONDARY RADIATION INTENSITY TO SEQUENTIALLY SELECT CORRESPONDING ONES OF THE PRESET SWITCHES OF EACH SAID SWITCH GROUP, SAID MOTOR MEANS BEING ENERGIZED FOLLOWING SAID SEQUENTIAL SELECTION.
