An exhaust emission control method for treating exhaust gas emitted from an internal combustion engine is provided in which an emission control device located in an exhaust gas passage of the engine stores SOx when the air / fuel ratio of exhaust gas is lean, and releases the stored SOx when the temperature of the emission control device is raised to a desulfurization temperature or higher and the air / fuel ratio of the exhaust gas becomes substantially equal to the stoichiometric air / fuel ratio or rich. In the method, a temperature control process is performed to control the temperature of the emission control device to be within a predetermined temperature range whose lower limit is substantially equal to or higher than the desulfurization temperature, and a desulfurization process is performed to release sulfur from the emission control device by controlling the air / fuel ratio of the exhaust gas to be substantially equal to the stoichiometric air / fuel ratio or rich when the temperature of the emission control device is within the predetermined temperature range. In the method, the temperature control process and the desulfurization process are repeated when sulfur is to be released from the emission control device.

A prosthetic tricuspid remodeling annuloplasty ring for use in tricuspid valve repairs to provide annular support after reconstructive valve surgery. The ring maintains an optimal annular dimension to prevent excessive dilatation of the natural valve annulus while adapting to the dynamic motion of the tricuspid annulus during the cardiac cycle. An exemplary ring features a waveform contour and may be constructed of a titanium core having a varying cross-section for selective flexibility for good Z-axis or out-of plane movement. The “waveform” contour and selective flexibility of the different segments of this ring are designed to adapt to the complex motion of the annulus. This reduces the stress on the anatomical structures and therefore minimizes the risk of arrhythmia and ring dehiscence.

A tool is provided for preventing the rotation of a downhole tool or rotary pump stator, the tool comprising a tubular housing and a jaw which is biased radially outwardly from the tool to engage the casing wall for arresting tool rotation and providing significant stabilization of a rotary pump. In doing so, the tool housing moves oppositely to rest against the casing opposite the jaw. The tool housing and the downhole tool are thereby restrained and stabilized by the casing wall. The tool's jaw is released by opposite tool rotation. Preferably, the jaw is biased outwardly from the tool housing to a casing-engaging position by a torsional member, housed along the axis of the hinge of the jaw. The tool is released from the casing by opposite tool rotation which increasingly compresses the jaw toward the housing, twisting the torsional member into torsion, which then acts to urge the jaw outwardly again. Overextension of the jaw during assembly is prevented using cooperating stops in the jaw and the housing.

A bearing temperature-monitoring device and a bearing device with the bearing temperature-monitoring device. In the bearing temperature-monitoring device, occurrence of flaws on a rotating shaft caused by contact between the shaft and a metal temperature-sensing member facing the surface of a bearing member is prevented.This prevents a reduction in bearing-load carrying ability caused by the flaws and also prevents damage on the rotating shaft induced by the flaws. As a result, reliability of the bearing temperature-monitoring device is enhanced. The bearing member has an installation hole bored in the bearing member so as to penetrate to its inner surface; the temperature-sensing member relatively movably fitted in the installation hole to cause a temperature detection end surface to face a bearing surface of the bearing member, having a projection amount-limiting section for limiting the amount of projection of the temperature-sensing member to the bearing surface side, and formed from a material having a higher heat conduction rate than the bearing member; a pressing member for pressing the temperature-sensing member to the bearing member side such that the temperature-sensing member is movable by a specific amount from a projection amount limitation position to the side opposite the bearing surface; and a temperature detector electrically connected to the temperature-sensing member and detecting the temperature of the temperature-sensing member.
