Abstract: The system includes a first magnetic plate mounted in a generally upright position at a first location adjacent a conveyor and adapted to hold thereagainst a plurality of objects each having a magnetizable material therein. The plate has two slots therein and a movable finger in each slot which is adapted to engage the top side of the object for sequentially moving objects downwardly onto the conveyor. A second magnetic plate is mounted in a generally upright position at a second location downstream from the first location and adjacent the conveyor. A vertically reciprocal ram powered by a pneumatic cylinder is situated at the second location and is adapted to move upwardly to sequentially move objects from the conveyor onto the second plate as each object reaches the second location.

Abstract: A mixing device adapted to bubble air through a sample solution in a reaction tube without disturbing the tube and without carrying any contaminating portion of the sample solution into the next tube whose sample solution is to be mixed by the same device. The device includes a cylinder having a piston connected with an air injecting probe adapted to be lowered into the reaction tube and to inject bubbles and thereafter to be retracted into the cylinder while at the same time wiping the exterior of the probe by means of a cylindrical curtain of air. Means are provided to retain the probe in retracted position until the next mixing cycle.
