Abstract: A pitch training system for indicating whether a thrown baseball has passed through a strike zone includes a zone assembly for detecting a baseball passing through the zone assembly. The zone assembly indicates when the baseball passes through a strike zone as determined by the zone assembly. A backstop is aligned with and positioned a distance from the zone assembly. The backstop intercepts the baseball thrown through the zone assembly.

Abstract: A lime processing apparatus has a transportable base and a reaction vessel mounted on the base. The reaction vessel has an inlet end for receiving a pressurized flow of water and lime and has a discharge end. A mechanical agitator is rotatably mounted within the vessel interior for mixing the water and the lime within the vessel to form a slurry product and to move the slurry product through the vessel to continuously discharge product from the discharge end. An elevator mechanism on the transportable base elevates the discharge end of the reaction vessel whereby any unreacted solids in the slurry product are collected at the inlet end for removal through a solids discharge conduit.
