Abstract: A device and method used for inspecting and measuring coiled tubing, production tubing or drill pipe as it enters the well. Defects such as internal and external wall loss, cracking and deformation can be detected and quantified. The axial motion of the tubing can be measured allowing for depth measurements that are more accurate and reliable than what can be obtained using an encoder wheel system.

Abstract: The present invention relates to a method and a device for controlling an ultrasound tool unit for machining a workpiece on a machine tool. For this, a plurality of parameter sets are stored on a storage device of a control device of the machine tool. When controlling an ultrasound transducer of the ultrasound tool unit received on a work spindle of the machine tool on the basis of a sensor signal input into a controller by means of a generator operated by the controller, on the basis of a first parameter set, which is associated with the ultrasound tool unit and sets the operation of the controller, an operating setting of the controller is switched by changing the first parameter set setting the operation of the controller on the basis of a second parameter set, which is associated with the ultrasound tool unit, of the plurality of parameter sets stored on the storage device.

Abstract: A vibratory compactor is provided. The vibratory compactor may include a frame coupled to a compactor plate. The frame and compactor plate are configured to vibrate to compact soil. The vibratory compactor may also include a housing having an inner volume, the housing coupled to the frame by at least one isolator with the frame and the at least one load bearing member located within the inner volume. The housing may be coupled to an arm of an excavator. A gap may be formed between the housing and the frame, wherein the gap between the housing and the frame inhibits movement of the housing with respect to the frame through the housing contacting the frame when excess forces are applied to the housing in an up/down direction, a forward/backward direction, a side-to-side direction, or combinations thereof.

Abstract: A vibratory compactor is provided. The vibratory compactor may include at least one load bearing member coupled to a load bearing base and a frame coupled to a compactor plate with the load bearing base coupled to the frame. The frame and compactor plate are configured to vibrate. The vibratory compactor may also include a housing having an inner volume, the housing coupled to the frame by at least one isolator with the frame and the at least one load bearing member located within the inner volume. The housing may be coupled to an arm of an excavator. In response to force being applied to the housing by the excavator during compaction, the housing moves with respect to the frame until a top member of the housing contacts the at least one load bearing member and compacts soil more effectively than a vibratory compactor without the load bearing member.

Abstract: A dual frequency ultrasonic and sonic actuator with constrained impact mass is presented. According to one aspect, displacement of the impact mass is constrained by cavity to which ultrasonic stress from the tip of a horn is applied. According to another aspect, the displacement of the impact mass is constrained by a spring attached to the tip of the horn. According to another aspect, the displacement of the impact mass is constrained by a flexure. The constrained impact mass converts the ultrasonic stress to lower frequency sonic stress that is coupled to a transmitting element for transmission through a surface. According to one aspect, the transmitting element is a longitudinal probe. According to another aspect, the transmitting element is a drill bit used to penetrate though the surface. According to another aspect, the transmitting element is a thumper used to transmit elastic waves though the surface.

Abstract: Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Erzeugen von Schlagimpulsen oder Schwingungen für eine Baumaschine, bei dem ein Kolben in einem Arbeitsraum in einem Gehäuse reversierend zwischen einem ersten Umkehrpunkt und einem zweiten Umkehrpunkt hin und her bewegt wird, wobei zum Erzeugen der Schlagimpulse beziehungsweise der Schwingungen der Kolben mittels eines Druckfluids in eine reversierende Bewegung versetzt wird und das Druckfluid im Bereich des ersten Umkehrpunktes und des zweiten Umkehrpunktes in den Arbeitsraum ein- und ausgeleitet wird. Nach der Erfindung ist vorgesehen, dass die Position des Kolbens mit einer Messeinrichtung erfasst wird, dass eine Steuereinheit abhängig von der erfassten Position des Kolbens mindestens ein steuerbares Ventil steuert, durch welches Druckfluid in den Arbeitsraum ein- und/oder ausgeleitet wird, wobei durch die Steuereinheit die Bewegung des Kolbens gesteuert wird.

Abstract: A novel mode of ultrasonic oscillation is generated in a Langevin ultrasonic transducer comprising a metal block, a metal block provided with a supporting means protruding in a ring shape on its side surface, and polarized piezoelectric elements fixed between these metal blocks, by connecting the ultrasonic transducer to a base via the supporting means, whereby supporting the ultrasonic transducer on the base in a restrained state, and applying to the piezoelectric elements a voltage having such frequency that the ultrasonic transducer generates an ultrasonic oscillation with back-and-forth motion in a direction perpendicular to plane surfaces of the piezoelectric elements which has no oscillation node within the ultrasonic transducer; this novel ultrasonic oscillation mode is utilized for performing ultrasonic machining methods as well as for ultrasonic transmission method.
