A pattern former for assembling wrapped bakery products into predetermined patterns comprises a perforated vacuum turntable. The feeder is provided with shielding that prohibits the livestock from access to the feeder storage bin, and is also provided with a rechargeable solar battery power supply allowing for use of the feeder in remote rural locations where there is no electrical power. The fluid circuit has a tilted heating section essentially aligned normally to the sun irradiation for heating and vaporization of the sewage water. The multi-level pulse sequence may be produced by a switch network having at least three different input voltage levels. The connector has a first linear part, a second linear part, and a folded portion that connects the first and second linear parts. The first and second unique signals may be stacked as a first stacked output and a second stacked output by a band translating circuit.
