Abstract: The batting practice device has a structure of a vertical member with a suspension beam attached to suspend a ball and a cross beam and leg beam to support the vertical member. An elastic cord is attached to the vertical member and routed through a corner pulley and an eyebolt to be attached to a ball line. The ball line is routed through one or more pulleys to suspend a ball from the suspension beam. The bottom attachment end of the ball line is attached to two anchor lines of which one is then attached to the cross beam right end and the other to the cross beam left end. The device may include a rotating cross beam to allow ease of storage. A beam pin is also provided to adjust the height of the ball above the ground.

Abstract: The refrigerated automatic fish feeder is an insulated cylindrical container having a removable cover and a motor driven rotating food tray. The food tray has food tray compartments to hold food and each food tray compartment has a trap door to allow dispensing of food at predetermined time intervals. The insulated container has a food drop door which opens at the same time as the trap door to allow the food to drop from the fish feeder into a fish tank. The fish feeder is cooled by use of a thermal electric device thermally connected between an external heat sink with a fan to dissipate heat and an internal heat sink. The movement of the food tray to dispense food and the operation of the thermal electric device for cooling is accomplished by an operation and control circuit having a fail safe circuit.
