摘要： 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.

摘要： 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.

摘要： A hydraulic vale 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 drive 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.

摘要： A Single Piezo-Actuator Rotary-Hammering (SPaRH) Drill includes a horn actuator having high power piezoelectric materials and a flexure pre-stress to increase the actuators effectiveness. The drill is a low mass, low power, compact coring drill measuring 20-cm high by 7-cm diameter and having a total weight of 2 kg including drive electronics. Using an average power of 50-Watts, the drill basalt is expected to cut basalt at a rate of 0.2 cm/min down to depth of 10-cm and create cuttings and an intact core. The drill is expected to operate under different environments including Martian ambient (6 Torr and down to −50° C.), and liquid nitrogen temperatures (77 K) and low pressure (

摘要： The design of the free-mass in an ultrasonic driller/corer (USDC) has been refined in order to improve the performance and operational reliability of the system. In one embodiment, the improvements in performance and operational reliability include decreasing the impact surface area of the free-mass to increase the transfer of impact energy from the piezoelectric transducer and reductions in the likelihood that the system will jam.

摘要： 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.

摘要： The present invention provides an ultrasonic and sonic mechanism of deep drilling (USMOD) that is driven by a vibrating actuator and operates in a similar manner to the gopher with regards to drilling debris removal. The actuator induces vibration in the form of a hammering actuation. The mechanism consists of a penetration bit with a diameter that is the same or larger than the actuator. The embodiment of the invention that is disclosed herein emulates a gopher. This ultrasonic gopher is lowered down into the produced borehole, cores the medium, breaks and holds the core, and finally extracts and deploys the core.A USMOD device consists of power drive and a drill-head. The power driver generates ultrasonic pulses to activate the USMOD mechanism and it allows optimized use of power by duty cycling the signal. The drill-head consists of an actuator, free mass and a penetration bit. The actuator consists of a vibration source and a horn that amplifies the amplitude of the vibration. The horn has a cylindrical cross-section to produce a drill-head that has cylindrical configuration and eliminate undesirable trapping of extracted soil and powdered cuttings. A cavity inside the tubular-shape horn provides space for packaging miniature instrumentation and sensors. The actuator activates an integrated free-mass that hammers the penetration bit, where the free-mass operates as a transformer to lower the vibration frequency to produce the hammering action. In one implementation of the USMOD it is designed to contain a trap for collection of upward traveling dust, debris and powdered cuttings.

摘要： A system and method for monitoring the properties of a fluid, such as water, in a steam pipe without mechanically penetrating the wall of the pipe. The system uses a piezoelectric transducer to launch an ultrasonic probe signal into the pipe. Reflected ultrasonic signals are captured in a transducer, which can be the same transducer that launched the probe signal. The reflected signals are subjected to data processing, which can include filtering, amplification, analog-to-digital conversion and autocorrelation analysis. A result is extracted which is indicative of a property of the fluid, such as a height of the condensed fluid, a cavitation of the condensed fluid, and a surface perturbation of the condensed fluid. The result can be recorded, displayed, and/or transmitted to another location. One embodiment of the system has been constructed and tested based on a general purpose programmable computer using instructions recorded in machine-readable non-volatile memory.
