Abstract
Abstract Process and apparatus adapted to supply sequentially a series of samples, normally liquid, at a sampling station for further processing such as by a conventional analyzer, wherein the samples are stirred or agitated magnetically to maintain them substantially in a homogenous condition. For this purpose, minute dipolar magnets are freely contained in the samples, and the supply device contains recovery means for recapturing the magnets after the samples have passed the sampling station. Dipolar master magnets are passed relatively to the freely-held magnets to induce their rotation. In a preferred form, a turntable carries the master magnets, and belt drive means jointly supports and rotates the turntable.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
113 words
Stirring or agitating apparatus including a container adapted to hold material to be stirred or agitated, a first dipolar magnet freely held within said container for independent movement to provide a stirring action by such Movement of the magnet itself, a plurality of second dipolar magnets supported seriatim and in fixed relationship to each other along a path, and means to move the container and said path of second dipolar magnets relatively to each other, so that the poles of said first dipolar magnet are magnetically coupled to the poles of successive ones of the second dipolar magnets along said path to induce said movement of the first dipolar magnet within the container.
Claim 2
Dependent Claim
113 words
Stirring or agitating apparatus including a container adapted to hold material to be stirred or agitated, a first dipolar magnet freely held within said container for independent movement to provide a stirring action by such Movement of the magnet itself, a plurality of second dipolar magnets supported seriatim and in fixed relationship to each other along a path, and means to move the container and said path of second dipolar magnets relatively to each other, so that the poles of said first dipolar magnet are magnetically coupled to the poles of successive ones of the second dipolar magnets along said path to induce said movement of the first dipolar magnet within the container.
Claim 3
Dependent Claim
50 words
The apparatus of claim 1 wherein said container is stationary, and said second dipolar magnets are so supported along said path to move the opposite poles thereof in tandem along said path successively to attract and repulse the poles of said first dipolar magnet and induce a rotary movement thereof.
Claim 4
Dependent Claim
54 words
The apparatus of claim 1 wherein said container is stationary, and said second dipolar magnets are so supported along said path to move like poles thereof in tandem along said path successively to attract the pole of said first dipolar magnet that is opposite to said like poles and induce a reciprocable movement thereof.
Claim 5
Dependent Claim
71 words
The apparatus of claim 1 wherein a plurality of said containers, each freely holding a first dipolar magnet, are arranged in essentially a circle, said plurality of said second dipolar magnets is carried on a periphery of a rotatable turntable mounted for rotation essentially concentric with and adjacent to said circle of containers, and said means to move the containers and second dipolar magnets relatively to each other rotates the turntable.
Claim 6
Dependent Claim
19 words
The apparatus of claim 1 wherein said first dipolar magnet is plastic-coated to minimize inadvertent adherence to said container.
Claim 7
Dependent Claim
76 words
A process for stirring material within a container comprising placing a first dipolar magnet in said container for free, unimpeded movement therein, successively passing a plurality of second dipolar magnets relatively past the container, successively magnetically attracting the poles of said first dipolar magnet by the relative passing of the poles of said second dipolar magnets to induce movement of said first dipolar magnet within the container and thereby impart a stirring movement to said material.
Claim 8
Dependent Claim
76 words
A process for stirring material within a container comprising placing a first dipolar magnet in said container for free, unimpeded movement therein, successively passing a plurality of second dipolar magnets relatively past the container, successively magnetically attracting the poles of said first dipolar magnet by the relative passing of the poles of said second dipolar magnets to induce movement of said first dipolar magnet within the container and thereby impart a stirring movement to said material.
Claim 9
Dependent Claim
45 words
The process of claim 6 wherein like poles of said plurality of second dipolar magnets are moved in tandem along said path successively to attract the pole of said first dipolar magnet that is opposite to said like poles and induce a reciprocable movement thereof.
Claim 10
Dependent Claim
43 words
The process of claim 6 wherein alternately arranged north and south magnetic poles of said plurality of second dipolar magnets are moved along said path successively to attract and repulse the poles of said first dipolar magnet and induce a rotary movement thereof.
Claim 11
Dependent Claim
36 words
The process of claim 6 wherein a plurality of said containers is arranged along a predetermined path, each container having a first dipolar magnet, and said plurality of second dipolar magnets is moved along said path.
