摘要:
A logging plug is disclosed having an internal sealing mechanism therein which provides a high degree of sealing integrity between the bore of the plug and a coiled tubing or other means of suspending wellbore equipment running therethrough. The sealing mechanism utilizes a combination of low friction, elastomerically-energized cap seals and ring seals to ensure that the sealing surfaces adapt continuously to the changing profile of the coiled tubing to provide a true dynamic seal around the coiled tubing.

A tubing conveyed tool for use in perforating a well bore utilizing abrasive perforating techniques. The perforating tool is particularly useful in non-vertical wells. The perforating tool is designed to permit running and setting a bridge plug, and then perforating the well bore without requiring the removal of the tool string. An eccentric weight bar can also be used to allow for directional perforating in non-vertical wells. The eccentric weight bar uses gravity to cause the bar to rotate to a predetermined position.

摘要:
In a press having a lower stationary platen, an upper movable platen, a hydraulic ram that travels with the upper platen, light-duty cylinders that position the upper platen, and a gate mechanism that closes above the ram to permit the ram to drive the upper platen during compression phases of operation, method and apparatus for adjusting the clearance between the upper and lower platens. A number of cylindrical spacers can be distributed, as desired, between an upper end of the ram and a spacer retaining mechanism located above the gate mechanism. The spacers are shaped to vertically interlock to form a stable stack atop the ram. The retaining mechanism extends downwardly from an upper cross-head of the press and is received in the interior of the stack of spacers. The retaining mechanism has spring-biased locking members that can locate below an internal lip of any spacer. To remove spacers, the ram is raised until all spacers seated on the ram interlock with any spacers supported by the retaining mechanism. All spacers are then raised until the locking members engage a lowermost one of the spacers to be removed. The ram is then simply lowered, retaining the a desired number of spacers. A similar procedure is followed to add one or more spacers, but a hydraulic cylinder is actuated to retract the locking members to release the spacers.

A mobile apparatus has a first articulating section comprising a leading traction control assembly including multiple points of contact inclined at a forward angle, and a second articulating section comprising an intermediate traction control assembly. A propulsion system is configured to coordinate movement of the leading traction control assembly and the intermediate traction control assembly. A connector operatively couples the first articulating section to the second articulating section, and the first articulating section is configured to articulate relative to the second articulating section in response to one or more of the multiple points of contact of the leading traction control assembly coming into contact with an obstacle. A bias assembly is configured to exert a continuous compression force against one or both of the first articulating section and the second articulating section to maximize the number of points of contact between the mobile apparatus and the obstacle.
摘要:
A silicon integrated circuit device comprising a near intrinsic silicon substrate in which there are one or more ohmic contact regions. An insulating layer lies above the substrate, and on top of the insulating layer is a lower layer of one or more aluminium gates. The surface of each of the lower gates is oxidised to insulate them from an upper aluminium gate that extends over the lower gates.

An in-vehicle entertainment system. The system is mounted on the ceiling of the vehicle and faces the rear seat. There is a housing to receive a left and right screen and a switcher mounted in the middle. The switcher has various inputs such as a DVD, music DVD or movie DVD. The audio is received in speakers or headphones in combination with the screens. There can be an auxiliary screen that can be mounted anywhere in the vehicle. The vehicle radio may be connected to the switcher in such a manner to play through the switcher audio system.
