Abstract: An electrical discharge stock prod having a circuit that prolongs battery life by monitoring power input and modifying the prod discharge characteristics. The circuit allows the prod to deliver a consistent voltage level to discharge electrodes, even though the power sources may vary. Preferably, the circuit is operated by a micro-controller. Additionally, by virtue of an improved transformer configuration (which lowers the voltage potential between the primary and secondary cores) and strategically placed polypropylene (which reduces carbon arcing) and increased isolation between primary and secondary windings within the transformer, safety of the prod is substantially enhanced. Preferably, the voltage to the discharge electrodes of the prod can be infinitely adjusted within a predetermined range of voltages, energies, and/or pulse rates to allow the prod to be effectively used on subjects having different physical parameters.

Abstract: An animal watering system includes a storage device, that has a bottom, a top, a mouth located within the top, and a plurality of sides, and a drinking device that is designed to dispense a liquid and to receive the bottom of the storage device. The storage device includes a selectively openable and closable port system and a sealing mechanism for sealing the mouth of the storage device. A method of using an animal watering system is also provided. The method includes the steps of placing a first cap on an orifice in the storage device, filling the storage device with a liquid through a top of the storage device, sealing the top of the storage device, placing the storage device within the drinking device, and removing the first cap from the orifice.

Abstract: A bearing is described for use with a disc harrow including means for preventing dust from entering the interior thereof. The bearing comprises inner and outer bearing rings having a plurality of spaced apart ball bearings mounted therebetween. First and second ring shaped seals are positioned between the inner and outer bearing rings at the opposite sides thereof. First and second ringshaped shroud caps embrace the first and second seals, respectively, for maintaining the seals in position. A sealant material is positioned between the inner and outer bearing rings at each side thereof so as to prevent soil from entering the interior of the bearing between the shroud caps and the outer bearing ring, and from reaching the primary bearing seal area.
