Title: Method and apparatus for intermitiently applying particulate powder material to a fibrous substrate
IPC: B05B15/04
Filed: 1992-12-11
Abstract: An apparatus and method for applying particulate powder material to a moving fibrous substrate (58) is disclosed. The apparatus includes a volumetric dry material feeder (22) for forming a continuous stream of particulate powder material. The continuous stream is then transmitted through a nozzle (38) and exits at an outlet (42) thereof. The nozzle is movable between a first and second position (47, 49) by a motion control. The motion control includes an adjustable differential gear box and an encoder for synchronizing the dispensing of powder at a predetermined location of the substrate. A flow separator (41) is disposed beyond the outlet (42) of the nozzle (38) and intermediate of the first and second positions (47, 49). In operation, the motion input drives the nozzle (38) to oscillate between the first and second positions (47, 49) at a variable speed over each product cycle. As the nozzle (38) crosses a plane of the flow separator (41), the continuous stream of particulate powder material exiting the nozzle (38) is split into two intermittent streams of particulate powder material. The first intermittent stream is applied to a predetermined location of the moving fibrous substrate (58) to form a layer of particulate powder material within a predetermined portion of the substrate (58). The second intermittent stream is recirculated back to the volumetric dry material feeder (22). <IMAGE>

Abstract: 本发明涉及一种高频肖特基二极管的电化学制作方法，包括如下步骤：1)用电化学工艺在半导体表面上形成阳极氧化多孔绝缘薄膜；2)把阳极氧化多孔绝缘薄膜作为形成肖特基二极管的掩膜；3)用电化学阳极氧化腐蚀和镀金工艺首先腐蚀掉半导体表面层，然后通过镀金法在多孔氧化薄膜的孔中淀积金属，形成金属/化合物半导体肖特基接触界面和肖特基二极管。

Abstract: 为了支持空气冷却的燃气涡轮机组的冷却，本发明提出：在冷却系统的冷却空气导管中设有用于流动的冷却空气的压力升高的装置。在一个实施形式中，冷却系统(17)由一个燃气涡轮机组(1，2，3，4)的压缩机(1)的末级供给高压压缩空气。该冷却系统分出第一分支(18)，通过它使燃烧室(2)及第一级、尤其是涡轮机(3)的第一引导级冷却。第二分支(19)将冷却空气导入其它的涡轮机级。为了按需要提高通过冷却系统第一分支(18)供给的压力降，设有一个喷射器(20)。对它的驱动喷嘴(22)供给由一个余热蒸汽发生器(51)取出的新蒸汽(9)，其中新蒸汽(9)的输入可通过一个调节机构(21)调节。本发明被证实普遍地适合于灵活地构成冷却空气预压力及由此适合于构成冷却空气质量流。
