Abstract: Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include an inner member having a stent receiving region, a stent disposed along the stent receiving region, a deployment sheath axially slidable relative to the inner member, the deployment sheath having a proximal end region, a handle coupled to the deployment sheath, a rod coupled to the handle, the rod having a distal end region, a proximal end region and a first threaded portion extending from the distal end region to the proximal end region and a coupling member configured to couple the rod to the deployment sheath, the coupling member having an engagement portion. Additionally, the first threaded portion of the rod is designed to engage the engagement portion of coupling member and rotation of the rod is designed to translate the coupling member along the rod.

Abstract: A sealant spreader device fills voids around a drilled hole with sealant in glued-in-rod (GIR) structures. A liquid sealant may be applied to the base of a drilled hole. A sealant spreader device is then inserted to the base of the drilled hole, through the sealant. The sealant spreader device is then withdrawn while rotating. The sealant spreader device includes winged sections having contours which force the sealant radially outward toward walls of the hole, into any voids around the circumference of the drilled hole, and leaves a thin layer of sealant around the circumference of the drilled hole.

Abstract: A vacuum sealing device includes a plug which is thrust into the port of an insulated steam injection tubing for closing an annular space of the tubing which confines a vacuum. The plug is mounted for movement within a first mounting element and for movement within a bellows having an end connected to the first mounting element. A second mounting element is connected to the opposite end of the bellows and carries a rod which is fixed to the plug. By moving the two mounting elements together, the bellows is compressed and the plug is thrust by movement of the rod. The first mounting element is connected to an upper clamping section which cooperates with a lower clamping section to engage around a tubular to be plugged. The upper section can be correctly centered with its plug over the port of the tubular by momentarily compressing the bellows to extend the plug. The plug is provided with a shank portion and a breakable tab for breaking the plug away from the shank portion.

Abstract: A thermal overload relay characterized by a housing containing a plurality of pole units, two pairs of spaced terminals on the housing, one terminal of each pair comprising a stationary contact within the housing, a movable contact mounted on and extending from the other of each terminal and being biased in one of the open and closed positions of the stationary contact, a slide within the housing for moving the movable contact between said positions, latch means on the slide for latching the slide in one of said positions and being spring biased in the other position, reset means for moving the slide to a latched position, each pole unit having a bimetal element responsive to current flow to effect heating thereof, and means associated with the latch means for unlatching the latch means.

Abstract: A thermal overload relay characterized by a plurality of pole units, stationary and movable contacts, a slide within the housing for moving the movable contact between open and closed positions, a movable contact mounting arm on the slide, latch means on the slide for latching the slide in one of said positions, resetting means for moving the slides to the latched position, each pole comprising a bimetal element responsive to current flow to effect heating thereof, a crossbar associated with the bimetal element to effect unlatching of the latch means, and the housing being an integral single unit into which the several foregoing elements are inserted in place.
