Abstract: A magnetic device for magnetically coupling to a ferromagnetic body, comprises a housing having a central bore. A plurality of pole sectors arranged within an envelope of the central bore and forming a workpiece contact interface of the magnetic device, each of the plurality of pole sectors comprising a plurality of spaced-apart pole portions arranged at respective distances, wherein a recess of a plurality of recesses separates each pole portion of the plurality of pole portions, wherein a first sector forms a first pole of the magnetic device and a second sector forms a second pole of the magnetic device. A first permanent magnet. A second permanent being moveable relative to the first permanent magnet. And, an actuator operatively coupled to the at least one second permanent magnet to move the at least one second permanent magnet relative to the at least one first permanent magnet.

Abstract: An animal watering system, such as a bird bath, incorporating a water reservoir, a means to automatically maintain the level of water in the reservoir by admitting fresh water thereto, an animal access basin positioned above the water reservoir whereby water overflowing the basin enters the reservoir, an air lift pump for transporting water from the reservoir to the basin by way of a fountain head and fountain catch basin, and an air compressor for providing a source of compressed air to operate the air lift pump.

Abstract: This patent presents a method of operating an apparatus and the apparatus which is a pneumatically operated fluid pump including a compressed air driven blow chamber which forces fluid into a collecting and measuring means that is emptied via siphoning techniques to control a blow and flood regulator responsive to the weight of the collected fluid.

Abstract: A system for the collection and storage of energy, wherein compressed air from any source is utilized to make a fully automatic, sequential series of chamber-to-chamber blow-type vertical water lifts to an elevated water storage reservoir. Potential energy stored in the reservoir is extracted by means of an hydraulic air compressor located below the reservoir and functioning by virtue of the resultant pressure head.

Abstract: A system for converting a constant pressure head of water into compressed air which may be utilized to transfer the potential energy of the pressure head to remote work sites.
