Abstract: An apparatus using differential gearboxes to collect, combine, and transmit torque generated by multiple, interconnected rotor systems. The rotor systems are connected via a driveshaft. The driveshaft is connected to a generator gearbox, and the generator box drives an electrical generator. The torque may be converted to mechanical power by replacing the electrical generator with a mechanical power device. The rotors are activated by fluid currents such as wind or water.

Abstract: The convertible bar-puller provides a convertible tool for automatic lathes. This tool has two main parts; a housing head and a shank. The housing head is attached to the shank using an adjustable connection means allowing the housing head to be positioned vertically with respect to the shank. The shank includes flat sides and radius corners to be received in either an internal tool housing or an external tool housing on the turret of the lathe. Positioning of the head on the shank in a first position fixed with the shank even with the upper end of the housing head adapts the tool for an external tool housing while fixing the head in the middle of the shank adapts the tool for an internal tool housing. Jaws for engaging the object to be machined extend forwardly from the head and have an adjustable jaw opening. The jaws each comprise a finger portion and an end portion, the end portion received in a circular groove on a jaw setting screw internal to the head.

Abstract: A bar puller is provided having adjustable jaws comprising fingers made of a resilient material. The fingers extend forward from a housing adapted to be mounted at a tool station of a computer numerically controlled lathe having a turret. Front and side guiding surfaces are provided on the ends of the fingers to cause the jaws to deflect outwardly and grip a bar when forcibly engaged therewith. The lathe chuck releases the bar allowing the bar puller to withdraw the end of the bar a desired distance out of the chuck. The chuck is closed while the turret continues moving away from the chuck causing the bar to be withdrawn from between the jaws of the bar puller, readying the machine for its next cycle.
