Control apparatus for automatic chemical testing apparatus

Abstract

Abstract FIRST BOARD AS THE CONVEYORS INDEX WITH THE SECOND BOARD HAVING CONTACTS ELECTRICALLY CONNECTED TO AND CONTROLLING SAMPLE DISPENSING, REAGENT INJECTING AND THE READOUT MEANS AS THE SECOND BOARD INDEXES. A REAGENT SELECTION BOARD HAVING A PLURALITY OF POSITION RECEPTACLES CORRESPONDING TO POSSIBLE POSITIONS FOR INJECTING REAGENTS INTO THE TUBES AND CONNECTED TO THE REAGENT INJECTING MEANS AND ELECTRICALLY CONNECTED TO THE SECOND MOVABLE CONTACT BOARD FOR ACTUATION AS THE SECOND BOARD IS INDEXED. THE IMPROVEMENT IN A CONTROL APPARATUS IN A CHEMICAL TESTING APPARATUS IN WHICH A PLURALITY OF REACTION TUBES ARE CARRIED BY A LOOP CONVEYOR SEQUENTIALLY THROUGH VARIOUS POSITIONE WHERE SAMPLES ARE DISPENSED IN THE REACTION TUBES AT A FIRST POSITION, REAGENTS ARE INJECTED INTO THE TUBES AT PREDETERMINED POSITIONS, AND READOUT MEANS ANALYZE THE CONTENTS OF THE TUBES AT A PREDETERMINED POSITION HAVING A DISCRETIONARY PROGRAM SELECTION BOARD WITH AN ACTUATING SWITCH FOR EACH TUBE CARRIED BY THE CONVEYOR FOR SELECTIVELY PROGRAMMING CHEICAL TESTS TO BE PERFORMED ON EACH SAMPLE. A FIRST ELECTRICAL CONTACT BOARD ELECTRICALLY CONNECTED TO THE PROGRAM SELECTION BOARD, AND A SECOND MOVABLE CONTACT BOARD MOVABLY INDEXED RELATIVE TO THE
