PATENT APPLICATION OF: Roger Bennison FOR: RANDOM SAMPLING SYSTEM ABSTRACT Apparatus and process for randomly selecting articles for removal from an advancing series thereof,. An operator chooses the total number of a batch of the articles from which the random selection is to be taken, as well as the total number of samples of the articles to be taken from the batch. A series of random numbers, each representing an incremental advancement of the series of articles, is developed when a reset button is actuated by the operator which interrupts a very long sequence of numbers held in the memory of a micro-computer, thereby establishing a starting point. A sensor senses the articles as they pass a predetermined station, and those articles are removed from the advancing series which relate in the sequence to each randomly generated number. Information is displayed which relates to the number of the batch, the number of samples, and the number of articles still to pass the predetermined station immediately prior to the next article scheduled for removal. The apparatus and process can also be used to remove random samples from an advancing flow of fungible material.
