    摘要: A stabilizer sleeve (7) for a drill string, adapted to fit about a down hole motor (1) or a drill string member, is formed with an internally threaded coupling at a lower end for releasable coupling to complimentary threads (8) formed on an upwardly extending intermediate coupling portion (15) of a bottom coupling-nut (3). The coupling-nut (3) is provided with a lower end portion (14) of larger diameter and an upper coupling portion (16) of reduced diameter. The upper coupling portion (16) is conventionally formed with an upwardly tapering form and right-hand thread whereas the intermediate coupling portion (15) is formed with a left-hand thread. The stabilizer sleeve (7) fits about the motor (1) or other body member and above the coupling-nut (3) so that the sleeve (7) may be removed upwardly from the coupling-nut (3).

    摘要: A drop-ball sub-assembly comprises a tubular casing (4) defining a flushing fluid flow passage adapted for coupling at one end (3) to an inlet pipe (1) and at the other end (23) to an outlet pipe (24). A drop-ball (17) supporting member (8) is secured within the casing (4) in the flow passage. Apertures (21) are arranged to allow fluid flow past the supporting member (8), and a further aperture (9) supports a blow-out device (13) supporting a drop-ball (17) on a side distal from the end (23). The blow-out device (13) and the apertures (21,9) are such that at a first, lower fluid rate from the inlet (3) to the outlet (23) end, fluid flows through said aperture (21) and the blow-out device is retained, and that at a second, higher flow rate the blow-out device (13) is blown out of the further aperture to release the ball (17) through the further aperture (9). The blow-out device suitably comprises a frangible disc.

    摘要: A downhole motor (19) is mounted in a drill pipe (13) above a hole enlarger (14) intermediate ends of the pipe (13). The motor drives a lower pilot bit (28). A split flow bypass device (24) above the motor (19) allows part of the flow to drive the motor and the remainder to bypass through a central passage, the divided flows rejoining below the motor (19) with a restricted flow through jet nozzles (32) to the hole enlarger cutter (15). Flow passes centrally of the output shaft (26), past a bleed valve (34) bleeding up to 5% to an outer shaft space for lubricating bearings (30), to flow restrictor jet nozzles (33) of the pilot bit (28). In use flow is controlled to drive the motor (19) to drive the pilot bit (28) at desired speed and the drill string is rotated from the rotary platform of a drill rig to drive the hole enlarger (14) so that the hydraulic requirements of the hole enlarger (14) and the pilot bit (28) are met while only allowing sufficient fluid to pass through the motor (19) to give the required output speed at the pilot bit (28).

    摘要: A method of controlling the direction of a drill bit (3) at the downhole end of a drill string (2) drilling from a surface comprises providing two steerable stabilizers (4, 5) at the downhole end of the drill string (2) at locations spaced apart in the drilling direction and adjusting the orientation of the stabilizers to create reactive forces from the bore hole (6) to deflect the course of the bit (3) in a desired direction. The stabilizers (4, 5) are suitably arranged eccentrically and circumferentially offset by 180.degree..+-.60.degree.. In normal drilling the drill string (2) is rotated such that stabilizers (4, 5) engage the bore hole (6) to support a downhole motor (1) against tilting. When off course drilling is sensed the stabilizers are rotated to a position and stopped from rotation such that drilling forces generate reaction forces to cause a desired change of direction.

    摘要: The present invention relates to a nail and fastener assembly for use in providing a stable construct for optimal fixation of the hindfoot and to methods for implanting the nail and fastener assembly. One embodiment of the nail and fastener assembly provides additional fixation, for example, in the form of one or more threaded bores, to hold the fasteners in a fixed position. Another embodiment provides angled bores to allow multi-planar and multi-axial implantation of the fasteners. In some instances, the fasteners may cross one or more articulating surfaces of the foot. For example, the fastener may traverse one or more of the calcaneo-cuboid and the talo-calcaneal articulating surfaces to aid in more secure stabilization of the hindfoot.

    摘要: A framework for providing multi-device collaboration is described herein. In one embodiment, a method for providing multi-device collaboration between first and second devices can include transferring an initializing function call to create a session object. The function call specifies a mode of the session object, a service type, and a service name. The session object can include functions to discover the second device, connect with the second device, and provide data transport between the connected first and second devices. The service name can include a truncated name, a unique identification, and a state of service of a software application associated with the first device. The method can include detecting a network and advertising the service type and the service name via the network. The service type and service name can be advertised prior to establishing the connection between the first and second devices.

    摘要: In a liquid sensing system, an RF signal is applied to a series-resonant circuit. The coil of the resonant circuit is placed proximate to a fuel tank, causing electromagnetic radiation to propagate into the fuel space. The fuel acts as an electrical load to the resonant circuit in a manner proportionate to the volume of fuel in the tank and/or to variations in electrical properties of the fuel itself. The loading effect of the fuel can change the resonant frequency and/or the Q of the resonant circuit. The loading effect of the fuel is determined by monitoring a change in one or more electrical parameters associated with the excited resonant circuit, such as a voltage across the resistor in the resonant circuit. Changes in this voltage are analyzed by a controller, the result of which is used to output a value indicative of level and/or composition of the fuel.
