Abstract: A water wheel pet fountain includes a lower basin that holds water, a water wheel that lifts water from the lower basin and delivers it to a collector that has an outlet or spout that allows the water to exit the collector and fall back down into the lower basin in an exposed stream accessible to pets for drinking. A motor is removably carried on the basin and a removable cowl covers the water wheel. The fountain can be taken apart for cleaning and the electronics and motor can be separated from the components being cleaned. The parts that contact water have large fillets and can be made with an antimicrobial plastic.

Abstract: A rotary pump that utilizes falling water to produce useful energy. The pump is a conduit in a spiral form mounted on an axis that is set at an angle whereby when rotated, water flows into the inlet end of the conduit and is transported to an elevation. The conduit is powered by an impeller wheel that rotates by falling water.

Abstract: This invention is about water carrying lift that enables water to be used in watering fields (agricultural fields), energy production, etc by increasing the level of water in places like rivers, streams, creeks etc.

Abstract: A material classifier for classifying a liquid-solid mixture containing solid material to be separated. The material classifier includes a tank and an angularly mounted scoop wheel for scooping solid material which has settled on the bottom of the tank.

Abstract: A tower-like transfer device includes a cylindrical tower post having an upper post portion and a lower post portion constituted by connecting post constituent members of one kind or two kinds or more, a lift installed liftably to the tower post, an upper post lift for lifting the upper post portion, an integration device for integrating the post constituent member between the upper post portion disconnected from the lower post portion and the lower post portion and holding the upper post portion disconnected from the lower post portion in removing the post constituent member at an upper end of the lower post portion and a transfer lift installed liftably to the tower post.

Abstract: A system for evacuating sand, paraffin, and other particulate matter from an oil well, while simultaneously lifting the oil to the surface and stimulating its rate of production, comprises a series of transport units attached to an endless belt. The belt is positively driven between a wellhead station at the surface and a downhole module which is self centering within the well casing, thereby avoiding damage and wear to the casing. Preferably, the belt comprises a roller chain which enables the depth and rate of production of the evacuation system to be easily adjusted. The transport units are replaceably mounted on the belt and are specially designed to agitate and accumulate the particulate member in the oil well.

Abstract: A device for elevating water by means of a vertical chain (5,21) of buckets (10,20) supported and driven by an upper reversing wheel (7,25), the lower part of the bucket chain (5,21) running through a filling tank (1,15) having a height adjustable overflow edge (4,18) over which water from the lower level (2,19) may flow into the passing buckets (10,20). Structure (11,25') is provided for discharging the buckets (10,20) at the higher level (13,39). The bucket chain (21) in its entirety preferably is adjustable in the vertical direction.

Abstract: Horizontal basket extractors with a continuous conveyor with spaced baskets or cells are arranged with traveling splitters movable along the top and/or bottom runs of the conveyor synchronously with the baskets arranged to divert a continuous flow of solids and/or liquids from a preceding basket to a following one, thereby eliminating the intermittent feeding of the material being charged in succession but avoiding passage of the material through the spaces between the baskets.
