62results about How to "Avoid longitudinal displacement" patented technology

Devices and methods are provided for reducing the lateral displacement of an endovascular device, e.g. a stent graft, within an aneurysm sac. A stabilization system comprising one or more stabilizing elements is inserted within the aneurysm space between an implanted device and the vessel wall. Filling this space prevents changes in curvature of the implanted endovascular device, and prevents longitudinal displacement, thereby providing for improved long-term stability and durability of endovascular repair.

A protector (10) has two half members (20, 40) forming a tubular shape upon being assembled. One half member (20) includes a pair of temporary fixing ribs (26A, 26B) projecting more than a contact edge (23) with the other half member (40) and standing up at the opposite sides of each of corrugated tubes (80A, 80B), each pair of temporary fixing ribs (26A, 26B) are shaped to be insertable into grooves (81A, 81B) of the corresponding corrugated tube (80A, 80B), and stand-up ends (27A, 27B) of the pair of temporary fixing ribs (26A, 26B) are bent to approach each other along the groove (81A, 81B) of the corrugated tube (80A, 80B).

For oil production systems, an interior two-part seal ring of resilient material is disposed within a coupling sleeve which receives threaded tubing ends in its opposite ends. The seal is asymmetric, with tapered ends of different lengths and taper angles. A length for mill end engagement is shorter than the length for field end engagement which may be made up and disconnected repeatedly. The seal configuration includes a principal body with a inwardly directed ridge between its tapered ends and a reinforcing ring of different, less permeable material, abutting the ridge and closing off one or more radial ports in the wall of the body. The central body also includes a circumferential gas groove about is periphery, which together with the radial ports, facilitates collection and release of gases permeating the seal body under high down-hole pressures.

A corrosion-resistant tension member, particularly a tendon for prestressed concrete, comprising a bundle of tension elements arranged inside a sheathing, has at its ends anchoring devices each with an anchor plate. On the side of the anchor plate facing away from the open air side, a seal having tension elements running through it and having a sealing plate are arranged, the sealing plate being fixed in place on the side facing away from the anchor plate opposite the anchor body against longitudinal displacement. Between the anchor plate and a pressure plate butting against the sealing plate, pressure-transferring means, for example, a pressure tube, are provided, having a length calculated in such a way that a longitudinal displacement of the anchor plate that occurs when the tension elements are being tensioned, actuates the exertion of surface pressure to the sealing plate for activating the seal.

An improved method and structure for connecting a prescribed number of solar battery modules in series. Corresponding electrical connectors are attached to the terminal ends of cables extending from each solar battery module in the system and to the ends of relay cables that are joined in series to form a relay cable assembly. The relay cable assembly is thus able to provide a sequential series of connector pairs whose number equals the number of solar battery modules to be connected. The series joined relay cables in the relay cable assembly are connected to the output cables of each solar battery module in the system, thus providing an improved method of connecting a prescribed number of solar battery modules in series.

Tools and techniques for providing protection to a foot and leg with a shin guard compression sleeve underlying a shin guard are presented. A shin guard compression sleeve may comprise a toe shoe having individual toe apertures and pockets intended to contain the toes of a foot received therein, and, an elastic tubular liner operatively associated with the toe shoe. The elastic tubular liner may compressively receive a portion of a leg and have a length sufficient to extend beyond the top of a shin guard receiving the sleeve, such that the tubular liner defines a first layer under the shin guard, and a second layer overlapping the first layer when folded over. The second layer may hook over an end portion of the shin guard, thereby sandwiching the shin guard between the first and second layers of the elastic tubular liner.

Rear engageable surfaces (16B) of engageable portions (16) face communicating portions (37) and are inclined to produce forces for pushing another housing (11) forward in a connecting direction with one housing (21) upon receiving resilient restoring forces of leg portions (51) when a pair of connectors (10, 20) reach a properly connected state. A fitting portion (27) of the second connector (20) is formed with slanted surfaces (46) inclined to reduce the width of the fitting portion (27) toward the back side of the fitting portion (27). The slanted surfaces 46 and the first connector (10) are set to come into contact at a position where a clearance is defined before the first connector (10) in the connecting direction with the second connector (20).

A tool includes a tool body and a cutting portion detachably mounted thereon, the tool being rotatable about a longitudinal center axis. The tool body includes flutes formed in an outer surface thereof, and a pair of forward projections at a front end thereof. The cutting portion includes front flutes formed in an external side thereof, and a pair of recesses extending circumferentially in communication with respective ones of the front flutes. To connect the cutting portion to the tool body, the cutting portion and tool body are converged longitudinally so that the projections enter the front flutes. Then, relative rotation is produced between the cutting portion and tool body to align the front flutes with the rear flutes while causing the projections to enter the recesses and form therewith a bayonet coupling.

A flexible member air spring has an end section of the flexible member attached to a connecting part by a clamp ring. The connecting part has a slot having a truncated cone-shaped cross section.
