摘要： An offshore riser system has riser joints, each having a pin and a box. The pin has an external grooved profile that is engaged by a locking element carried by the box of another riser joint. An actuating ring engages with the locking element to move it into the locked position. A retractable spider supports the string of riser while the new joint is being made up. A makeup tool on the riser deploying floor moves the ring relative to the locking element, causing the locking element to move to the locked position.

摘要： A wellhead seal assembly forms a metal-to-metal seal between inner and outer wellhead members. A metal seal ring has inner and outer walls separated by a slot. A lock ring has grooves for locking the inner wellhead member to the outer wellhead member during installation. An energizing ring has a C-ring captured on its inner surface. When the energizing ring is moved further into the slot, the C-ring is forced from its pocket and engages the surface of the inner wellhead member, locking the seal assembly to the inner wellhead member.

摘要： A rotating drilling head seals around drill pipe while drilling. The drilling head has an outer housing that mounts to the rig floor. An inner housing is rotatably mounted in the outer housing. An annular bladder is mounted in the inner housing. An annular elastomeric gripping member is mounted in the bladder. The inner housing having a passage for delivering hydraulic fluid pressure to the outer surface of the bladder to cause the bladder to deform inwardly, thereby forcing the gripping member to deform inwardly to grip and rotate with a drill pipe. The gripping member has a first end secured to the inner housing for rotating the inner housing as the drill pipe rotates and a second end that is free to move axially to allow the bladder to elongate in response to the deformation by the bladder.

摘要： An assembly contained within a housing slideably connects device leads to apparatus terminals with predetermined forces. Parallel slots through the housing contain “S” shaped rotatable contacts. The connection force is obtained by compressing two elastomeric members extending through holes perpendicular to the slots and opposite to the contact ends by rotating the contacts. The leads and terminals are opposite and parallel to opposite ends of the contacts, and their connection is provided by this contact rotation. The contact rotations are provided by the nose ends of the contacts extending outward slightly from the slots such that, when the device under test is pressed against the housing, the contacts will be forced within the housing to rotate the contacts and compress the elastomeric members. This provides both a sliding and predetermined force electrical connection between the leads, terminals and contacts.
摘要翻译： 包含在壳体内的组件以预定的力将设备引线可滑动地连接到设备端子。 通过壳体的平行狭槽包含“S”形可旋转接触。 连接力是通过旋转接触件来压缩延伸穿过垂直于狭槽的孔并与接触端相对的两个弹性构件而获得的。 引线和端子相对并且平行于触点的相对端，并且它们的连接由该接触旋转提供。 接触转动由接触件的端部稍微从狭槽延伸提供，使得当被测试装置被压靠在壳体上时，接触件将被迫在壳体内以旋转接触件并压缩弹性体构件。 这提供了引线，端子和触点之间的滑动和预定的力电连接。
