    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: A check-type valve assembly in which an annular channel is formed in a valve body. A port is formed in the inner surface of the channel and is closed by an elastic band which is positioned under tension in the channel so as to bear tightly against the inner surface thereof. The elastic band functions as a valve element for controlling the flow of fluid through passages communicating with said port and the annular channel.
