An animal identification and feeding apparatus having a plurality of tags, one suspended from each animal, each tag having a plurality of pockets into which either permanent magnets or non-magnetic filler strips are press fit to form a code. The code is detected by a plurality of spaced reed switches having field modifying magnets interposed between the reed switches. The tag magnets and the field modifying magnets are polarized along an axis of magnetization which is perpendicular to their interfacing surfaces and they are aligned with repelling poles facing each other.

Identification and animal feeding apparatus

An optical inspecting apparatus for detecting the absence of an object from a cavity of a slat filling machine. The inspector detects the empty cavity, determines the container which will be short filled and tracks the container and causes the ejection of the container from the production line. Discrete photodiodes lined along the cavity path are actuated in sequence and phototransistors detect whether light passes through the slat. The control computer using data in its memory analyzes the result of scanning through the diodes to determine the short filled bottle and causes its ejection as it passes an ejection station.
