摘要： A nosepiece for directing a charge into a crucible of a furnace. The nosepiece comprises a completely enclosed sleeve which more accurately directs the charge into the crucible. The sleeve has a distal portion that deflects the charge toward a center area of the crucible, thereby minimizing impact of the charge on the top edge of the crucible and its refractory liner. In addition, the nosepiece is split so that the distal portion is movable, thereby to provide access to an interior of the nosepiece. As a result, any bridging in the charge may be addressed by moving the distal portion to an open position.

摘要翻译： 用于将电荷引导到炉的坩埚中的鼻梁。 喷嘴包括一个完全封闭的套筒，可以更精确地将电荷引导到坩埚中。 套筒具有使电荷朝着坩埚的中心区域偏转的远端部分，从而最小化电荷对坩埚及其难熔衬里顶部边缘的影响。 此外，鼻梁被分割，使得远端部分是可移动的，从而提供对鼻梁的内部的通路。 结果，可以通过将远端部分移动到打开位置来解决充电中的任何桥接。

摘要： An exciter mass assembly for vibratory processing equipment includes an exciter frame and at least one resilient member connecting the exciter frame to the vibratory processing equipment. A motor is supported by the exciter frame so that the exciter frame and motor define a frame center of gravity. The motor includes a rotating shaft defining a shaft center of gravity. The prime mover is positioned with respect to the exciter frame such that the shaft center of gravity is substantially coincident with the exciter mass center of gravity, thereby to minimize movement of the exciter mass assembly in unintended directions.

摘要： An annular heat exchanger suitable for a gas turbine engine includes a first continuous sheet of material arranged in a spiral and a second continuous sheet of material arranged in a spiral. A first axially extending passage is defined between the first surface of the first sheet and the third surface of the second sheet and a second axially extending passage is defined between the second surface of the first sheet and the fourth surface of the second sheet. The first passage is closed at its axial ends by spiral seals between the first sheet and the second sheet. The second passage is open at its axial ends. A plurality of radially extending passages are provided to supply a first fluid at a first end into the first passage, to remove the first fluid from a second end of the first passage and to interconnect adjacent turns of the first passage. The passages extend radially through the second passage.
