Sizer accuracy was not greatly decreased by increased speed of chain movement up to 46 f . Of the four sizers tested, the chain sizer was the only satisfactory device for a high-capacity sys- tem. The square-link chain appeared satisfactory for accuracy, introduction-submersion character- istics, and potential capacity in these preliminary trials. Testing of Pilot Model Hydrosizer A sizing mechanism (fig. 14) similar in design and construction to the test mechanism previously described, was installed in the laboratory test tank. It was constructed so that it could be fitted with a square-link chain having openings of 24, 2, or 314 inches, or with a hexagonal chain with open- ings of 2 inches. The sizing unit was driven hydraulically. Two chain speeds were employed: 'fast', in which the linear translation of the chain was approximately 64 f ., and 'slow', approxi- mately 37 f . The water flow in the tank was adjustable; it was set so that the sizing device was kept nearly loaded with apples. A typical test of the sizer was conducted as follows: (1) The water flow was established in the tank; (2) the test apples were placed in the water in the dump and feed area; (3) the sizer was started and operated until all apples were sized; and (4) the two sizes of fruit were accumulated and evaluated for quality. Fruit Bruising Studies of fruit bruising were made with Mc- intosh apples initially bruise-free. The apples were individually selected on the tree, placed on pla
