Abstract: A pair of spaced-apart cam disks disposed along a common power shaft, with a pair of cam followers disposed within channels formed in opposing inner surfaces of the cam disks, forms a balanced arrangement for creating linear reciprocating motion from the rotation of the pair of cam disks. A linear motion shaft is coupled to the cam followers. As the cam disks synchronously rotate and the cam followers trace the path formed by the paired channels, this rotational motion is converted into linear, reciprocal motion that provides the translational movement of the linear motion shaft.

Abstract: An inlet arrangement for a tray-based grit removal system utilizes a set of separate inlet hoses to connect the vertical stack of trays to a horizontally-disposed inlet chute, thus eliminating the inlet duct utilized in prior art configurations. Each hose is configured to have about the same length and diameter, providing an essentially uniform influent pressure at the input to each tray. The hoses are directly connected between the trays and the inlet chute, where each tray may be formed to include a hose coupler of the same diameter as the hose. The inlet chute may take the form of a trough or tube (or other suitable geometry), with the plurality of hoses all terminating along a common, horizontal output face of the chute.
