  • Patent number: 4919798
    Abstract: A method and apparatus for sorting articles passing an inspection station and subsequently removing selected articles from a transporting track.

A signal is generated by the pointer for removing the article from the track. The position of the article is determined by the pointer and at least two fixed points on either side of the inspection station. The pointer and the fixed points are fitted with an ultrasonic transmitter and a receiver, respectively, or the other way round, or with a combined transmitter/receiver.
