    • A hand-held sail device is disclosed and includes a sail sized and shaped to define an airfoil configuration. The sail includes an upper edge, a lower edge and a leech edge. A frame supports the sail and includes a mast having front and rear end portions and is adapted for securing the upper edge of the sail, and a boom which also has front and rear end portions and is adapted for securing the lower edge of the sail. A hand gripping member is disposed on the windward side of the sail and has top and bottom end portions pivotally secured, respectively, to the rear end portions of the mast and the boom. A first connector mechanism joins the front end portions of the mast and the boom. A second connector mechanism pivotally interconnects the gripping member top end portion with the mast rear end portion, while a third connector mechanism pivotally interconnects the bottom end portion of the gripping member with the boom rear end portion. Finally, a mechanism as provided for limiting the pivotal movement of the gripping member away from the sail.
    • 公开了一种手持帆装置,其包括尺寸和形状以确定翼型构造的帆。 帆包括上边缘,下边缘和水蛭边缘。 框架支撑帆,并且包括具有前端部和后端部并且适于固定帆的上边缘的桅杆以及还具有前端部和后端部并且适于固定帆的下边缘的吊杆。 手抓部件设置在帆的迎风侧,并且具有分别枢转地固定到桅杆和悬臂的后端部的顶端部和底端部。 第一连接器机构连接桅杆和起重臂的前端部分。 第二连接器机构将夹持构件顶端部与桅杆后端部枢转地相互连接,而第三连接器机构将夹紧构件的底端部与动臂后端部枢转地相互连接。 最后,提供一种用于限制夹持构件远离帆的枢转运动的机构。

    • A paper coating system is characterized by an upstream dip roll applicator that applies an excess layer of liquid coating material onto a surface of a paper web, and an improved downstream doctor assembly for metering and leveling the coating on the web. The doctor assembly includes a doctor blade having a tip extended against and across the web and a shear plate, upstream of the blade, having a surface extending across and defining a gap with the web. An elongate chamber defined between the shear plate and blade extends across the web, and excess coating removed from the web by the blade flows into the chamber. Coating is drained from and uniformly along a lower end of the chamber at a rate to maintain an eddy current pool of coating in an upper end of the chamber immediately upstream of the blade/web nip, but to prevent formation of a liquid seal in the gap. The eddy current pool of coating rewets the excess coating on the web just prior to the blade to level and smooth streaky film split patterns that occur from dip roll application, so the blade doctors the coating very uniformly and a very uniform coating is on the finished paper sheet. To further improve uniformity, the shear plate is adjusted so that the gap is sufficiently small to prevent any outflowing coating from spattering onto the incoming web, yet large enough to prevent formation of a liquid seal in the gap.
    • 纸张涂布系统的特征在于上游浸渍辊施加器,其将过量的液体涂覆材料层施加到纸幅的表面上,以及改进的下游刮刀组件,用于计量和调平幅材上的涂层。 医生组件包括刮刀,其具有抵靠并穿过腹板的尖端,以及在叶片上游的剪切板,具有横跨并且与腹板间隙限定的表面。 限定在剪切板和刀片之间的细长室延伸穿过纸幅,并且通过刀片从纸幅移除的多余的涂层流入该室。 涂层从腔室的下端排出并沿着腔室的下端以一定的速度被排出,以便保持喷雾涡流池在紧邻叶片/腹板压区上游的腔室的上端,但是为了防止在 间隙。 涂层的涡流池在刀片之前将多余的涂层重新润湿网片上的多余涂层,从而使浸渍辊施加时产生的平滑条纹膜分裂图案,因此刀片对涂层进行了非常均匀的涂覆,并且在成品上涂抹了非常均匀的涂层 纸张 为了进一步提高均匀性,调节剪切板使得间隙足够小以防止任何流出的涂层溅射到进入的幅材上,但足够大以防止在间隙中形成液体密封。
