  • Publication number: 20150244198
    Abstract: Provided is a self-regenerative charging device. The device includes an inverter configured to receive a direct current (DC) signal from a power supply and provide an alternating current (AC) signal to a load. The charging device also includes a charger having an input terminal configured to receive the AC signal output from the inverter, the charger including one or more output terminal pairs. The power supply includes one or more batteries, each having a battery terminal pair. Each of the one or more charger output terminal pairs is configured for connecting to only one of the battery output terminal pairs.

  • Publication number: 20080238104
    Abstract: A pressurized water powered machine that generates electrical power and is capable of driving a load which includes a waterwheel located above a water reservoir, a water pump that pressurizes water collected from the water reservoir and conveys it to a storage tank where it is stored under pressure for delivery to a water nozzle output which directs the pressurized water to the waterwheel, where the waterwheel powers a drive shaft that powers an electrical generator and is capable of being connected to a load.

  • Patent number: 5419288
    Abstract: A rotary internal combustion engine comprising a housing containing a rotatable cylinder having a circular wall containing at least two rows of radially extending circular passageways forming compression and power engine cylinders, respectively, displaced from each other along the axis of rotation. Each of the engine cylinders contains a freely reciprocal and rotatable spherical piston. A stationary cam is mounted within the housing surrounding each of the rows of engine cylinders, each cam consisting of a pair of edges circular in diameter whose axis coincides with the axis of rotation of the rotatable cylinder. Each pair of edges is in contact with all of the spherical pistons within its respective row, the spacing of the edges varying over 360 degrees of rotation so that the spherical pistons move at a uniform velocity within each cylinder.

  • Patent number: 5415135
    Abstract: An rotary internal combustion engine consisting of a rotatable cylinder made up of fuel charge and multiple working segments rotating in unison. The fuel charge and working segments each contain a plurality of radially arranged cylinders open at both ends and a spherical piston in and freely movable within each of the cylinders. A stationary cam surrounds the cylinder having cam surfaces to contact the spherical pistons within each of the cylinders causing each piston in its respective cylinder to reciprocate as the cylinder rotates. A stationary core is located within and enclosed by the rotatable cylinder for supplying and carrying away working fluid into and from the cylinders as well as igniting and delivering fuel charge to the working segments. An alternative embodiment consists of a sealing arrangement between the pistons and cylinders utilizing rings with pressure balancing to reduce friction.

  • Patent number: 5257599
    Abstract: An internal combustion engine in which various engine functions are carried out simultaneously rather than sequentially with the result that engine operation is smoother, less subject to vibrational forces, and has greater efficiency due to the elimination of the need to overlap functions. The engine comprises a rotatable cylinder made up of fuel charge, combustion, and working segments rotating in unison. The fuel charge and working segments each contain a plurality of radially arranged cylinders open at both ends and a spherical piston in and freely movable within each of the cylinders. A stationary cam surrounds the cylinder having cam surfaces to contact the spherical pistons within each of the cylinders causing each piston in its respective cylinder to reciprocate as the cylinder rotates. A stationary core is located within and enclosed by the rotatable cylinder for supplying and carrying away working fluid into and from the cylinders.

  • Patent number: 5080050
    Abstract: A rotary internal combustion engine having spherical pistons mounted in radially arranged cylinders formed in a stacked series of rotatable cylindrical members. A stationary cam surface is located around the rotatable member to maintain contact with the pistons. A stationary member located with the rotatable cylindrical member provides fresh fuel mixture, withdraws exhaust products, and provides ignition as required. Power is taken from the rotating cylindrical members at the end of the engine through a planetary gear train.
