    Abstract: A flow control valve for use in oil well bore holes is described. The flow control valve includes a plurality of flow paths connected in parallel. The flow control valve operates by successively opening different flow paths, starting with a flow path that requires a reduced force to operate its inlet valve. The flow rate through the flow control valve is conveniently controlled by opening and closing different ones of the plurality of flow paths individually or in combination. A flow path that allows fluid to flow at substantially the full flow rate of the valve is provided as one of the parallel paths. A simple mechanical design using poppet valves and at least one cam is described. The flow control valve provides advantages including digital control of the flow rate, low operating power requirements and abrasion resistance in the presence of particulates in the fluid.

    Abstract: A hydraulic valve controller that uses an existing pressure differential as some or all of the power source for valve operation. In a high pressure environment, such as downhole in an oil or gas well, the pressure differential between the inside of a pipe and the outside of the pipe may be adequately large to drive a linear slide valve. The valve is operated hydraulically by a piston in a bore. When a higher pressure is applied to one end of the bore and a lower pressure to the other end, the piston moves in response to the pressure differential and drives a valve attached to it. If the pressure differential is too small to drive the piston at a sufficiently high speed, a pump is provided to generate a larger pressure differential to be applied. The apparatus is conveniently constructed using multiport valves, which can be rotary valves.

    Abstract: A mechanism for drilling or coring by a combination of sonic hammering and rotation. The drill includes a hammering section with a set of preload weights mounted atop a hammering actuator and an axial passage through the hammering section. In addition, a rotary section includes a motor coupled to a drive shaft that traverses the axial passage through the hammering section. A drill bit is coupled to the drive shaft for drilling by a combination of sonic hammering and rotation. The drill bit includes a fluted shaft leading to a distal crown cutter with teeth. The bit penetrates sampled media by repeated hammering action. In addition, the bit is rotated. As it rotates the fluted bit carries powdered cuttings helically upward along the side of the bit to the surface.

    Abstract: The present invention provides a source of plurality of radiation types using a single source that is made of ferroelectric material in the form of a cathode. The generated radiation types consist of ion and electron beams, X-ray, visible light and ultraviolet radiation. These types allow testing the surface and bulk of the same medium while placed in the same location and are providing confirmation and independent measurements of the material properties. The cathode is made with a continuous electrode on one side and a grid shape electrode on the other. This cathode is supported with fixtures that are used to produce various radiation types. Also, control elements are used to define the shape and directivity of the emitted beam. The present invention eliminates the need for plurality of instruments for obtaining required properties of test materials covering both the surface and the bulk of the test medium. The disclosed source emits multiple types of charged particles and radiation using switchable electromechanical elements. The source performance is enhanced by use of a ferroelectric wafer with a high dielectric constant, and the control of the driving pulse shape. A set of stacks and arrays of multiplexed ferroelectric cathode wafers are used to offer various options in the design of the Ferrosource.

    Abstract: A monolithic ultrasonic horn where the horn, backing, and pre-stress structures are combined in a single monolithic piece is disclosed. Pre-stress is applied by external flexure structures. The provision of the external flexures has numerous advantages including the elimination of the need for a pre-stress bolt. The removal of the pre-stress bolt eliminates potential internal electric discharge points in the actuator. In addition, it reduces the chances of mechanical failure in the actuator stacks that result from the free surface in the hole of conventional ring stacks. In addition, the removal of the stress bolt and the corresponding reduction in the overall number of parts reduces the overall complexity of the resulting ultrasonic horn actuator and simplifies the ease of the design, fabrication and integration of the actuator of the present invention into other structures.
