Abstract: An upper magnet and a lower magnet respectively above and below the objects to be degaussed/demagnetized. They are arranged with their fields mutually transverse, and both at 45.degree. angles to a conveyor carrying the objects between the magnets. Either or both magnets may be rotated, selectively, and they are rotated in opposite directions.

Abstract: The articles to be degaussed are carried along on a conveyor under which is a magnet rotating on an axis extending through the conveyor and the articles.

Abstract: A machine having a conveyor for carrying a workpiece to be magnetized therethrough. It includes two demagnetizing magnets arranged at a mutual angle of 90.degree. and both at 45.degree. to the direction of travel on the conveyor. The magnets are arranged respectively above and below the conveyor, and hence above and below the workpiece on the conveyor, and are spaced apart in the direction of travel of the conveyor. The conveyor, structurally, includes a stationary base, and endless belts carrying paddles, the paddles engaging the workpieces and moving them along the base. The workpieces "float, " capable of moving to any position according to the condition of magnetism in them and the position and shape of the demagnetizing magnets, and upon encountering the field of the demagnetizing magnet that is disposed above the workpieces, the workpieces are capable of being attracted up to that demagnetizing magnet, off of the base of the conveyor.

Abstract: A fill belt (conveyor) carries boxes successively to a fill position where the magnetic articles (steel needles) are introduced into each box. They are fed from a vibrating bowl, controlled by a solenoid actuated gate. As the articles approach the box in a spout, they are demagnetized to facilitate flow thereof. As they are placed in the box they are magnetized in the box to align them in proper position. This magnetizing alignment is performed in a series of steps, and they are demagnetized after each step, including the final step when they are in their final condition for use. The quantity of articles in a box is sensed by a Hall generator sensor which utilizes the magnetic field in the articles for producing a control signal. While the articles are being deposited in the box, the spout is reciprocated along the path of the fill belt through the range of the box.
