    摘要： An optically-active air-clad fiber (30) includes a core (34, 84) that facilitates doping with an ion optically excitable and having a three-level optical transition when pumped at a first end (28) of an optical cavity (46) by a multimode pump source (72) at a pump wavelength (64) for lasing at a signal wavelength (66) different than the pump wavelength (64) at a second end (29) of the optical cavity (46), the core (34, 84) having a refractive index, wherein the core (34, 84) is transformed from the first end to proximate the second end (29) thereof such that the optically-active fiber (30) is multimode at the pump wavelength proximate to the first end (28), and is single-mode at the signal wavelength proximate to the second end (29). An air-clad (36, 86) surrounds at least one portion of the core (34, 84) and has a lower effective refractive index than the refractive index of the core (34, 84).

    摘要： A dual position handle and cam stop assembly is provided which is adapted for limiting rotational movement of an associated valve sealing element such as a ball for a ball valve. However, the assembly is applicable to other types of valves such as butterfly and plug valves. The assembly comprises a cam disc and a valve handle having associated first and second handle stop and direction indicators. The indicators are disposed relative to the cam disc for engagement against the disc at first and second handle stop limit locations, respectively. The locations are selectively positionable by rotation of the cam disc while maintaining a constant relative angular spacing for limiting the rotational movement of the valve handle to the constant relative angular spacing. The cam disc has a cardioid-like contour about its peripheral wall for a constant angular displacement of the stop limit locations per a unit degree of cam rotation. The handle stop and direction indicators preferably comprise a symmetrical flat-faced cam follower.

    摘要翻译： 提供了一种双位置手柄和凸轮停止组件，其适于限制相关联的阀密封元件（例如用于球阀的球）的旋转运动。 然而，该组件适用于其他类型的阀，例如蝶阀和旋塞阀。 组件包括凸轮盘和具有关联的第一和第二手柄止动件和方向指示器的阀手柄。 指示器相对于凸轮盘布置，用于分别在第一和第二手柄停止极限位置处与盘接合。 这些位置可以通过凸轮盘的旋转选择性地定位，同时保持恒定的相对角度间隔，以将阀把手的旋转运动限制为恒定的相对角度间隔。 凸轮盘围绕其周围壁具有心形状轮廓，用于每单位凸轮旋转程度的停止极限位置的恒定角位移。 手柄停止和方向指示器优选地包括对称的平面凸轮从动件。

    摘要： A ball valve is disclosed having an improved seat ring particularly adapted for sealing a ball member in an end-loaded or top-loaded valve body. The ball is mounted for selective rotation and limited axial movement in a valve body passageway. The seat rings are disposed on diametrically opposite sides of the ball about valve inlet and outlet openings. Frusto-conical disc springs interposed between each seat ring and an associated valve body shoulder urge the seat rings into engagement with the ball. A rigid reinforcing ring is disposed intermediate of the flexible seat ring for integral movement with the seat ring and for reinforcing the seat ring against collapse under pressure. The reinforcing ring is received in an annular channel about the periphery of the seat ring and preferably comprises a split metal ring in a stressed and expanded condition.
