摘要： A shaving unit for an electric shaver which comprises an outer cutter and an inner cutter associated to that outer cutter. The cutters are mounted so as to be movable relative to each other and adapted to be set in a relative motion by a drive mechanism. The inner cutter provides a plurality of cutting edges and abuts with its outer face on the inner face of the outer cutter. The outer cutter provides a plurality of teeth equipped with cutting edges. The outer cutter provides two comb elements which are disposed opposite one another and which extend according to the direction of the relative motion. The two comb elements are aligned with respect to one another such that the tips of the teeth of the first comb element are facing the tips of the teeth of the second comb element, the tips of the teeth spaced from one another.

摘要： A rotational alignment system determines the angular relationship between two or more elements of a drill string using one or more sensors that detect one or more reference objects positioned on the drill string. A control unit determines the rotational or angular offset between two or more elements on the drill string using measurements made by the sensor(s). In one application, rotational offset values are used by a surface logging computer to correlate sensor data provided by a logging tool.

摘要： A system and method provides a flow measurement system for steady-state and transient flow. A housing contains a sleeve such that the sleeve is isolated from external mechanical loads. A flow measurement element, such as a venture or nozzle, is located in the sleeve. Strains along the sleeve caused by flow pressure changes through the flow element are detected and related to fluid flow rate.

摘要： The present invention provides an electromagnetic telemetry apparatus and methods that include an insulating connector that comprises an outer metallic female member that has an inner conical longitudinal surface. In one embodiment, a tubular metallic male member is disposed in the female member, thereby crating an axial conical gap between the male and female members. A conical metallic sleeve having dimensions that substantially correspond to the axial conical gap is disposed in the axial conical gap. The outer tubular surface of the male member is coated with an insulating material, such as a ceramic material. A shoulder at one end of the male member prevents axial movement of the sleeve in one direction and a parallel key between the female member and a stabilizer member prevents rotational movement between the male and female members. The sleeve remains stationary relative to the insulated surface of the male member when the male and female members move longitudinally relative to each other. In an alternative embodiment, a double pin is connected between a lower section and an upper section. Insulation is provided at one end of the double pin. A loading sleeve disposed around the pin absorbs compressional stress and also electrically isolates the upper and lower sections.

摘要： An apparatus for drilling directional wellbores is disclosed that in one non-limiting embodiment includes a drive for rotating a drill bit, a deflection device that enables a lower section of a drilling assembly to tilt about a member of the deflection device within a selected plane when the drilling assembly is substantially rotationally stationary to allow drilling of a curved section of the wellbore when the drill bit is rotated by the drive and wherein the tilt is reduced when the drilling assembly is rotated to allow drilling of a straighter section of the wellbore, and at least one seal that isolates at least a surface of the member from outside environment. The at least one seal is lubricated by a sealed hydraulic unit

摘要： A flow-off telemetry system and method of communicating information from a downhole location in a borehole to a surface location while fluid circulation is off. A string is conveyed in the wellbore to define an inner bore and an annulus. During a flow-off condition, an inner bore sealing element closes the inner bore to create a first standing column of fluid in the inner bore, and an annulus sealing element closes the annulus to form a second standing column of fluid in the annulus. A bypass valve in the string at a downhole location between the first standing column of fluid and the second standing column of fluid is activated to generate a pressure pulse including information for performing an action. The pressure pulse is received at a pressure sensor at the surface location and a controller performs an action in response to the information in the pressure pulse.

摘要： A drilling system and method of drilling a wellbore. The drilling system includes a tubing, an orientation device affixed to the tubing, a drilling sub having a housing having a first section and a second section, wherein the first section is coupled to a movable element of the orientation device, a shaft disposed in the housing, the shaft coupled to the drive and to the drill bit, and a pivot member coupled to the first section and second section of the housing. The second section of the housing tilts relative to the first section of the housing about the pivot member when the orientation device is rotationally stationary to allow drilling of a curved section of the wellbore. Rotation of the housing via the orientation device reduces the tilt between the first section and the second section to allow for drilling of a straight section of the wellbore.
