    • A storage and drinking container for pressurised beverages comprises a drinking vessel (1) having a lip (3) and a lid formed from a cap (5) and retaining ring (12). The cap (5) seals with a sealing surface (4) on the inside of the neck of the drinking vessel and is retained in place by fingers (8) engaging under a lip (3). The fingers 8 are retained in position by a retaining ring (12). Cooperating sets of cammed surfaces (10) and (13) on the cap (5) and retaining ring (12) act on rotation of the retaining ring to axially separate the retaining ring (12) from the cap (5), releasing the fingers 8 from under the lip (3) and permitting the lid to be removed. The invention provides a drinking vessel with a wide neck which can be reliably sealed without the necessity to provide screw threads on the outer surface of the drinking vessel (1).

    • Fiber optic collimators are disclosed for use in fiber optic rotary joints (20) providing for improvement in insertion loss performance. One embodiment of the fiber optic collimator has a gradient-index rod lens (61 ) possessing a pitch of less than one-quarter. Improvement in insertion loss arises due to the increase in the effective focal length of the lens as the pitch is reduced, allowing the collimator to achieve a longer working distance. The increase in the effective focal length is accompanied by an increase in the back focal length of the lens, compared to the zero back focal length of the more typical quarter-pitch gradient-index rod lens. The increased back focal length can be filled by a cylindrical glass spacer (64), to which an optical fiber (68) is attached, resulting in a collimator with very similar form factor to the usual quarter-pitch gradient-index rod lens collimator. The increased back focal length can also be filled by a form of right-angle prism (71 ), to which an optical fiber is attached such that the fiber is oriented at 90 degrees to the optical axis of the lens useful for applications of pancake-style hybrid slip rings wherein the desired direction of fiber ingress to the rotary joint is perpendicular to the rotation axis of the rotary joint.
    • 公开了用于光纤旋转接头(20)中的光纤准直器,用于提高插入损耗性能。 光纤准直器的一个实施例具有梯度指数棒状透镜(61),其具有小于四分之一的间距。 插入损耗的改善是由于间距减小而导致的透镜的有效焦距的增加而引起的,从而允许准直器实现更长的工作距离。 与更典型的四分之一间距梯度折射率棒透镜的零背焦距相比,有效焦距的增加伴随着透镜的后焦距的增加。 增加的后焦距可以由安装光纤(68)的圆柱形玻璃间隔件(64)填充,导致与通常的四分之一间距梯度折射率棒状透镜准直器非常相似的形状因子的准直器。 增加的后焦距也可以由直角棱镜(71)的形式填充,光纤被附接到该直角棱镜(71),使得光纤相对于用于煎饼的镜片的透镜的光轴成90度定向, 其中纤维进入旋转接头的所需方向垂直于旋转接头的旋转轴线。
