Abstract: An improved distribution feeder of circular disc type, for receiving articles at the central portion and exhausting them from a plurality of outlets at the periphery, having the upper surface provided with a slope highest at the center and slanting down toward the periphery and a vibrator for imparting vertical and rotational vibration to the distribution feeder, thereby facilitating free movement of the articles to eliminate undesirable accumulation of the articles at the closed outlets.

Abstract: A combination weighing machine, which is typically used for packing a plurality of articles in each bag or the like so that the total weight of each bag becomes nearly equal to a predetermined target weight, including a plurality of weighing balances for weighing the articles at the same time, arithmetic means for selecting some of these balances so that the total weight of the articles thereon meets with a predetermined condition and means for unloading the selected balances to collect the articles thereof and then loading them with new articles, respectively, to initiate the next cycle of operation; each balance being accompanied with at least two holding hoppers and corresponding memories, and means for distributing each batch of articles weighed by the corresponding balance to each hopper and supplying the weight of each batch to the corresponding memory, thereby subjecting all batches of articles in all holding hoppers to the combination selection of said arithmetic means with the contents of the corresp
