US Patent:

44132328, Nov 1, 1983

Filed:

Feb 11, 1981

Appl. No.:

6/233672

Inventors:

Lynn W. Most - Lakeland MN
Allen F. Most - Hastings MN

International Classification:

G01R 3312
G01N 2772

US Classification:

324236

Abstract:

A device for detecting metallic objects in a container having a substantial quantity of non-metals therein including a frame having a verticle portion with respect to the ground. Metal detecting means are mounted on the verticle portion of the frame such that the metal detecting means defines a plane of detection. This plane of detection has a length defined as "L" which is substantially equal to the length of the detecting means, and the plane has a width extending parallel to the ground and away from the detector equal to distance "R". A container means of non-metallic material may be provided for holding a quantity of non-metal which might contain metallic objects therein. The container has an effective or operative length less than or equal to L and a diameter less than 2R. Container means may be provided to rotate the container means about an axis of rotation parallel to length L and less than distance R from said detecting means. Alarm means for signalling the presence of a metallic object passing through the plane of detection during rotation of the support means is also provided.

Abstract:

A device for detecting metallic objects in a container having a substantial quantity of non-metals therein including a frame with metal detecting means mounted on the frame such that the metal detecting means defines a plane of detection. This plane of detection has a length defined as "L" which is substantially equal to the length of the detecting means, and the plane has a width equal to distance "R". A container means of non-metallic material is provided for holding a quantity of non-metal which might contain metallic objects therein. The container has a length less than or equal to L and a diameter less than 2R. Rotating support means for positioning the container in the plane of detection is adapted to rotate the container about an axis of rotation parallel to length L and less than distance R from said detecting means. Alarm means for signalling the presence of a metallic object passing through the plane of detection during rotation of the support means is also provided.
