    Abstract: A system employing individual sample capsules, each of inexpensive hollow body, open bottom construction with end tabs and cups formed in the body, a pair of horizontal rails on which the capsules are conveyed side-by-side past processing stations in stop and go fashion by the up-and-down action of the rails and to-and-fro movement of a pair of racks having teeth-engaging within the capsule body and moving the capsule in one direction when the rails are down, the teeth being free of the capsule to move in the opposite direction when the rails are up, with automatic means for dropping a capsule onto the rails, transferring a sample from a container to one of the cups in the capsule, adding reagents, filtering the reacted sample, transferring fluid from one cup to another, incubating the sample, performing a colorimetric reading and removing fluid from all cups prior to discard of the capsule, the system being essentially pneumatically operated using pneumatic logic controlled by triggers associated with the various components of the system.

    Abstract translation: 采用单个样品胶囊的系统，每个便宜的中空体，具有末端突出部的开放底部结构和形成在体内的杯子，一对水平轨道，胶囊以并排方式传送过去处理站， 通过轨道的上下动作和具有齿接合在胶囊主体内的一对齿条的往复运动，并且当轨道向下时使胶囊沿一个方向移动，齿不含 胶囊在轨道向上移动时以相反的方向移动，具有用于将胶囊放置在轨道上的自动装置，将样品从容器转移到胶囊中的杯中的一个中，加入试剂，过滤反应的样品，将流体从 一个杯子到另一个，孵化样品，在丢弃胶囊之前执行比色读数和从所有杯子中除去流体，该系统基本上气动地使用由触发器控制的气动逻辑 s与系统的各种组件相关联。
