Abstract
Abstract Equipment for the automatic determination of the chemical composition of liquids by sampling and by adding reagents, in which a plurality of sample cups are arranged in each of a plurality of magazines. The magazines move tangentially of a rotary table about whose periphery are arranged a plurality of processing containers. A transfer device reciprocates vertically and also reciprocates radially of the table to transfer liquid from the cups to the containers. The table rotates stepwise and reagents are added to the samples in the containers. Finally a suction pipe transfers liquid from the containers to the analyzer, at the same time that light shines through the cup from which the sample originated, thereby simultaneously to analyze and identify the specimen. The magazines move first in a stack perpendicular to their length, then in single file lengthwise, and finally in the reverse direction in a stack perpendicular to their length, as they are successively introduced into, moved through and ejected from the equipment.

Claim 1
Independent Claim
209 words
EQUIPMENT FOR THE AUTOMATIC DETERMINATION OF THE CHEMICAL COMPOSITION OF LIQUIDS BY SAMPLING AND BY ADDING REAGENTS, COMPRISING A PLURALITY OF LIQUID SAMPLE CUPS ARRANGED IN SAMPLE MAGAZINES WITH A PLURALITY OF SAID CUPS IN EACH OF SAID MAGAZINES, A ROTARY TABLE, MEANS FOR ROTATING SAID TABLE STEPWISE, PLURALITY OF PROCESSING CONTAINERS ARRANGED IN A PERIPHERAL SERIES ABOUT SAID TABLE, MEANS TO FORWARD SAID MAGAZINES TRANGENTIALLY OF SAID TABLE, MEANS MOVABLE VERTICALLY AND ALSO RADIALLY OF SAID TABLE FOR TRANSFERRING LIQUID FROM SAID CUPS TO SAID CONTAINERS, MEANS TO DISPENSE REAGENTS INTO SAID CONTAINERS, MEANS TO EFFECT A MEASUREMENT OF THE CHEMICAL COMPOSITION OF THE LIQUIDS IN THE CONTAINERS, MEANS TO REMOVE LIQUIDS FROM THE CONTAINERS AND TO RINSE THE CONTAINERS WITH WATER AND AIR DRY THE CONTAINERS, SAID REMOVING MEANS COMPRISING SUCTION PIPE, SAID DETERMINING MEANS RECEIVING LIQUID FROM SAID SUCTION PIPE, MEANS FOR SHINING LIGHT THROUGH SAID CUPS ON SAID FORWARDING MEANS THAT HAVE MOVED BEYOND SAID TABLE, AND FOR READING THE LIGHT THAT SHINES THROUGH SAID CUP TO IDENTIFY THE CUP THROUGH WHICH SAID LIGHT IS SHINING, SAID LIGHT-SHINING MEANS BEING SO POSITIONED RELATIVE TO SAID FORWARDING MEANS THAT THE LIQUID IN SAID DETERMINING MEANS WAS DRAWN FROM THE CUP THROUGH WHICH SAID LIGHT IS SHINING.

Claim 3
Dependent Claim
29 words
Equipment as claimed in claim 1, said rotary table having a liquid space therein into which said containers extend, and means for maintaining said liquid at a predetermined temperature.
Claim 4
Dependent Claim
21 words
Equipment as claimed in claim 1, and means for simultaneously recording data from said determining means and from said reading means.
Claim 5
Dependent Claim
87 words
Equipment as claimed in claim 1, said magazines being elongated and said cups being disposed in a series along the length of each said magazine, said forwarding means comprising means for forwarding a stack of said magazines toward said table with the longest sides of said magazines against each other, and then for forwarding the magazines past the table in the direction of the length of the magazines and in single file, with said magazines passing between said light-shining means and said reading means in single file.
