    • A distributed features system is disclosed which permits a telecommunication network to accommodate the creation of open multimedia services. In accordance with an embodiment of the present invention, protocol extensions for a distributed feature system are disclosed which accommodate a broader range of media choices than conventional telephony. Protocols are disclosed for internal calls between modules in the distributed feature system that permit a module to open and close any number of media channels to be utilized in the communication usage. A protocol is also disclosed for internal calls between modules in the distributed feature system that is more appropriate for a packet-switched reference implementation.
    • 公开了一种分布式特征系统,其允许电信网络适应开放式多媒体服务的创建。 根据本发明的实施例,公开了分布式特征系统的协议扩展,其适应比传统电话更广泛的媒体选择范围。 公开了分布式特征系统中的模块之间的内部呼叫的协议,其允许模块打开和关闭在通信使用中使用的任何数量的媒体信道。 还公开了一种协议,用于分布式特征系统中的模块之间的内部呼叫,其更适合于分组交换参考实现。

    • A garment to be worn conveniently and comfortably over the upper body of a seagoing person to gain protection from rain, wind, and/or cold, which includes an interior deflated fluid tight enclosure, i.e. a bladder, to be very quickly inflated inside the garment in a time of emergency. The deflated fluid tight enclosure covers at least the interior upper back portion of this garment and also covers at least the interior of the right and left chest portions of this garment. An inflating subassembly is operatively secured between the deflated fluid tight enclosure and to either the right or left chest portion of this garment. This inflating subassembly has an alternatively usable mouth and lung inflatable valved air intake-discharge communicating with the deflated fluid tight enclosure, and an alternatively usable filled compressed fluid valved cylinder discharge also communicating with the deflated fluid tight enclosure and having a coilable pullable lanyard. Then a pocket like subassembly is removably secured, by using loop and hook fasteners on the exterior of the garment at either the right or left chest portion and is non removably secured to the coilable pullable lanyard. This pocket like assembly fully covers and protects the inflating subassembly, until an emergency, when the seagoing person intentionally, readily, and quickly, pulls the pocket like assembly away from the garment, causing the pulling of the lanyard to activate the valve on the compressed fluid valved cylinder. The fluid tight enclosure is then quickly inflated, creating the buoyancy needed by this seagoing person.
    • 一种穿着方便舒适地穿在海上人身上的衣服,以防止雨,风和/或冷,其包括内部放气的流体密封外壳(即,膀胱),以在服装内非常快速地膨胀 在紧急情况下。 收缩的流体密封外壳至少覆盖该衣服的内部上部后部,并且还至少覆盖该衣服的左右胸部的内部。 充气子组件可操作地固定在收缩的流体密封外壳和该衣服的右胸部或左胸部之间。 这种充气子组件具有与放气的流体密封外壳连通的可替代地使用的口和肺可充气的阀进气 - 排出口,以及可替换地使用的填充压缩流体阀缸排出口还与收缩的流体密封外壳连通并且具有可卷绕的可拉出的挂绳。 然后,通过在右侧或左侧胸部的衣服外部使用环形和钩形紧固件,可拆卸地固定口袋状的子组件,并且不可移除地固定到可卷绕的可拉出的挂绳上。 这种口袋状组件完全覆盖并保护充气子组件,直到紧急情况为止,当海上人员有意地,快速地将口袋状组件从衣服上拉出时,导致系索拉动以致压缩压缩 流体阀缸。 然后,流体密封的外壳迅速膨胀,从而产生了该海上人员所需的浮力。

    • A froth flotation machine (40) having a rotary air-supply shaft (42) vertically disposed in a vessel (41) includes an impeller (50) comprising a series of interconnected blades (52,53). Extending radially and fixedly depending from a flat impeller plate (52) is a pumping blade extending over one-half the distance from the plate outer periphery to the shaft. Blade (53) is an air-inducing vane of lesser radial length which aids in inducing air from shaft (42) to pumping blades (52). The vane has a height less than 50% of the height of the pumping blade. The pumping blade has an L/H ratio of from 0.8 to 1.4 where L is its radial length and H is its vertical height. Slurry is pumped by the blades (52) from bottom of the vessel through a central aperture in a surrounding fixed stator base (56) having stator bars (55) extending upwardly and forming parallel-sided passageways (63,64) for pumped fluid.
    • 具有垂直设置在容器(41)中的旋转空气供应轴(42)的泡沫浮选机(40)包括包括一系列互连叶片(52,53)的叶轮(50)。 从平坦的叶轮板(52)径向和固定地延伸的是从板外周延伸到轴的一半距离的泵送叶片。 叶片(53)是径向长度较小的导风叶片,其有助于将轴(42)的空气引导到泵送叶片(52)。 叶片的高度小于泵送叶片高度的50%。 泵送叶片的L / H比为0.8到1.4,其中L是其径向长度,H是其垂直高度。 浆料通过来自容器底部的叶片(52)通过周向固定定子基座(56)中的中心孔泵送,其中定子杆(55)向上延伸并形成用于泵送流体的平行侧通道(63,64)。
