摘要： A method of forming a component includes depositing successive layers of a binder and first particles of a first material using a layering device to build a first green segment, depositing successive layers of the binder and second particles of a second material different than the first material using the layering device to build a second green segment, assembling the first green segment and the second green segment together to form a green component, and infiltrating the green component with a metallic infiltrant to form the component.

摘要： A method for controlling an automated drilling process on a work machine includes the steps of obtaining, from at least one input, data determining operations of the work machine; generating reference data based on the data determining previous operations of the work machine in substantially the same area; detecting a region of interest in the reference data; and controlling, in response to the work machine or its drilling process approaching a point corresponding to the region of interest in the reference data, the work machine to provide an operator with an option to manually assist the operations of the work machine at the point.

摘要： A system and method for geophysical data collection, for use with resistivity and induced polarization. The system and method include the use of a single voltage reference wire to which all voltage recorders or nodes are connected by means of a piercing wire connector, the voltage recorders providing a measurement of the potential voltage between the reference wire and the ground and allowing for calculation of relative voltage potentials between adjacent recorders.

摘要： A drill string rod and a drill string assembly includes a drill rod and a drill bit. The rod includes a threaded male end and a female end. An axially extending shoulder is provided at the male end and has an axial length greater than an outside diameter of the shoulder to provide a shoulder driven rod exhibiting enhanced guidance to achieve straighter holes and better collaring.

摘要： A retrievable core sampling assembly for latching to or relative to a rotatable tubular housing of a core sampling apparatus to allow the capture and retrieval of a core from a subterranean formation, the assembly comprising or including: a core catcher barrel for a core, the barrel being rotationally isolated from the tubular housing and cooperable with a core taking bit coupled to the rotatable tubular housing to retain a core, and a hammer for providing impact to the core taking bit along a longitudinal impact path that is or is substantially decoupled from the core catcher barrel so that when latched, rotation and impact of the core taking bit captures and passes core material from the formation to the core catcher barrel in manner that isolates a core in the core catcher barrel from rotation and impact forces.

摘要： A percussion piston for a rock drill machine having a pilot cylinder, a distributor and a pressure medium includes a control edge configurable to cause a change in the position of the distributor in a direction parallel to the axial direction of the percussion piston as the percussion piston moves in the impact direction (A) in relation to the pilot cylinder. The control edge of the percussion piston includes at least one notch provided on the outer periphery of the control edge and arranged to cause a start of a state change for the distributor before the control edge of the percussion piston passes by a corresponding control edge provided on the distributor or pilot cylinder.

摘要： An impact-driven tool includes a cylinder and a piston slidably inserted into the cylinder and has a large-diameter portion. The cylinder includes: a chamber on one end side; a chamber on the other end side; a communication path that allows the chamber on one end side and the chamber on the other end side to communicate with each other; and a valve chamber that is continuous with one end side in the axial direction of the communication path, and a valve body for piston lifting control that is incorporated so as to be movable up and down and is provided in the valve chamber.

摘要： A valve assembly for managing a flow of fluids in hydrocarbon development and production operations includes a valve body having an internal body cavity and a body bore intersecting the body cavity. A valve plug is located within the body cavity and is rotatable between an open position and a closed position. A sleeve is located between the valve plug and the valve body and is rotationally fixed to the valve body and remains rotationally static relative to the valve body as the valve plug rotates. A seal groove is located on a sidewall surface of the sleeve and circumscribes one of the sleeve openings. A seal assembly has a seal ring that is U shaped in cross section with an inner leg that engages the seal groove and an outer leg that extends out of the seal groove and engages one of the valve body and the valve plug.

摘要： The present invention is directed to a dynamic seal tube for use in pressurized fluid-driven down hole hammer drills. The dynamic seal tube is a tube that slides within the bore of the piston and the anvil portion of the drill bit and co-operatively acts to release different volumes of pressurized fluid from the lower chamber when the piston is in different predetermined positions.
