Abstract: A small-engine vehicle including a plurality of wheels, an internal combustion engine having a drive shaft interconnected to drive at least one of the wheels, and a generator. The generator includes a stator having a core disposed next to the engine and a winding disposed on the core. The generator further includes a flywheel-rotor apparatus surrounding at least a portion of the stator and having an aperture that receives the drive shaft. The flywheel-rotor apparatus is operable to magnetically interact with the stator to produce a first high-voltage, alternating-current signal in the winding, and to provide an inertia to the internal combustion engine. The generator further includes power circuitry electrically connected to the winding. The power circuitry receives the high-voltage, alternating-current signal and controllably generates a second high-voltage, alternating-current signal.

Abstract: A vehicle including a plurality of wheels, an internal combustion engine having a drive shaft interconnected to drive at least one of the wheels, a stator having a core disposed next to the engine and a plurality of wires disposed on the core in a three phase winding arrangement, and a flywheel-rotor apparatus surrounding at least a portion of the stator and having an aperture that receives the drive shaft. The flywheel-rotor apparatus is operable to magnetically interact with the stator to produce a three-phase alternating current in the wires, and provides an inertia to the internal combustion engine. The vehicle further includes power circuitry electrically connected to the wires. The power circuitry receives the three-phase alternating current and controllably generates a single-phase alternating current.

Abstract: The invention provides a stator for a three-phase induction motor including a core having a plurality of slots that receives wire. The stator further includes a first phase winding wound on the stator having first and second wires electrically connected in parallel. The first wire forms a first group of coils having a first pattern and the second wire forms a second group of coils having a second pattern different than the first pattern. The invention further provides a winding method for the stator.

Abstract: A method of forming fractures from a highly deviated or horizontal well bore penetrating a subterranean formulation. A well bore is drilled horizontally into a formation and the deviation in the direction of the well bore from the direction of the least principal horizontal stress is determined. Perforations or notches then are produced in casing cemented in the well bore. The notching is effected in such a manner that the direction of the perforation or notch is made perpendicularly to the direction of the least principal horizontal stress in the subterranean formation. A fracturing fluid then is introduced into the well bore at a predetermined rate and pressure to fracture the formation at the fracture initiation points created by the notches whereby fracture reorientation is minimized or eliminated.

Abstract: Lifting device which is a compact, pantographic-type jack with arms forming a pantograph, and driven by a central spindle. Lower arms are suitably linked to a base, with the upper arms suitably linked with respective lower arms. One of the upper arms is longer than the other of the upper arms, with the longer arm being provided with a movable support at a free end thereof, in turn having a device for fitting into or against an object to be lifted, such as an automobile. Furthermore, a support linkage is suitably secured between the movable support and the shorter upper arm.

Abstract: An improved method of forming a plurality of spaced substantially parallel fractures in a subterranean formation from a deviated well bore penetrating the formation is provided. The method comprises drilling a substantially vertical well bore into the formation and forming an initial fracture therein by applying hydraulic pressure to the formation. The in situ least principal stress direction in the formation is determined from the initial fracture and a deviated well bore is then drilled from the substantially vertical well bore into the formation at an angle and in a direction substantially parallel to the in situ least principal stress direction in the formation. Casing is placed in the deviated well bore, and a plurality of spaced fracture initiation points are created therein by forming a set of perforations of predetermined number and size through the casing and into the formation at the location of each of the fracture initiation points.
