  • Publication number: 20100231251
    Abstract: The terminals of a device under test are temporarily electrically connected to corresponding contact pads on a load board by a series of electrically conductive pin pairs. The pin pairs are held in place by an interposer membrane that includes a top contact plate facing the device under test, a bottom contact plate facing the load board, and a vertically resilient, non-conductive member between the top and bottom contact plates. Each pin pair includes a top and bottom pin, which extend beyond the top and bottom contact plates, respectively, toward the device under test and the load board, respectively. The top and bottom pins contact each other at an interface that is inclined with respect to the membrane surface normal. When compressed longitudinally, the pins translate toward each other by sliding along the interface. The sliding is largely longitudinal, with a small and desirable lateral component determined by the inclination of the interface.

  • Patent number: 7762319
    Abstract: 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. An energizing ring has a C-ring captured on its outer surface. When the energizing ring is moved further into the slot, the C-ring is forced from its pocket and engages a profile on the seal ring, locking the energizing ring to the seal assembly.

  • Publication number: 20100147533
    Abstract: A seal assembly for sealing between wellhead members in a wellhead, the assembly may include a seal element and a lockdown member. The seal assembly is attachable to either one of the wellhead members by coupling the lockdown member to a locking surface on the wellhead member. The lockdown member and locking surface may include corresponding profiles for mating engagement thereby preventing relative movement between the wellhead member and seal assembly.

  • Publication number: 20080149390
    Abstract: 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.

  • Patent number: 7255576
    Abstract: A test assembly for testing electrical performance of microcircuits contained in leadless packages has Kelvin contacts. Slider contacts in a plurality of contact assemblies slide compliantly to accommodate lack of coplanarity in terminals on the package. A resilient elastomeric block may be inserted through interior spaces of the contact assembly and in interfering relation with features of a housing that supports and aligns the contact assemblies, to apply force to the slider contacts to force them against the microcircuit terminals.

  • Patent number: 6896076
    Abstract: 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.

  • Patent number: 6854981
    Abstract: An assembly contained within a housing slideably connects device leads to apparatus terminals with predetermined forces. Parallel slots through the housing contain ā€œSā€ 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.

  • Publication number: 20040033705
    Abstract: 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.
