    • A method for determining a rate of change of longitudinal direction of a subterranean borehole includes positioning a downhole tool in a borehole, the tool including first and second longitudinally spaced surveying devices disposed thereon. The method further includes causing the surveying devices to measure longitudinal directions of the borehole at first and second longitudinal positions and processing the longitudinal directions of the borehole to determine the rate of change of longitudinal direction of the borehole between the first and second positions. The method may further include processing the measured rate of change of longitudinal direction of the borehole and a predetermined rate of change of longitudinal direction to control the direction of drilling of the subterranean borehole. Exemplary embodiments of this invention tend to minimize the need for communication between a drilling operator and the bottom hole assembly, thereby advantageously preserving downhole communication bandwidth.
    • 一种用于确定地下钻孔纵向变化率的方法包括将井下工具定位在钻孔中,所述工具包括设置在其上的第一和第二纵向间隔的测量装置。 该方法还包括使得测量装置在第一和第二纵向位置处测量钻孔的纵向方向,并且处理钻孔的纵向方向以确定钻孔在第一和第二位置之间的纵向变化率。 该方法可以进一步包括处理所测量的钻孔纵向变化率和纵向方向的预定变化率,以控制地下钻孔的钻孔方向。 本发明的示例性实施例倾向于最小化对钻井操作者和井底钻具组合之间的通信的需求,从而有利地保持井下通信带宽。

    • An overlapping or nesting connector is provided for connecting adjacent edge restraint sections. The edge restraint includes a substantially upright section and a base section, and may include braces extending between the upright section and the base section. The connector may be formed integrally with or separate from the edge restraint sections, and includes at least an upper wall, and optionally lateral walls and/or a rear wall. The upper wall may define an opening for a spike, and the brace or coupling structure with which the connector overlaps may define a corresponding opening for receiving the spike, which openings are aligned when the connector overlaps the brace. After adjacent edge restraints have been connected via the overlapping connector/brace, the spike is driven through the aligned openings into the underlying surface to provide a strong connection between the adjacent edge restraints and between the edge restraints and the underlying surface.
    • 提供重叠或嵌套连接器用于连接相邻的边缘约束部分。 边缘约束包括基本上直立的部分和基部,并且可以包括在直立部分和基部之间延伸的支架。 连接器可以与边缘约束部分一体形成或与边缘约束部分分离,并且至少包括上壁和任选的侧壁和/或后壁。 上壁可以限定用于钉的开口,并且连接器重叠的支架或联接结构可以限定用于接收钉的对应开口,当连接器与支架重叠时,该开口对准。 在相邻的边缘约束通过重叠的连接器/支架连接之后,尖钉被驱动通过对准的开口进入下面的表面,以在相邻的边缘约束之间以及在边缘约束和下面的表面之间提供牢固的连接。

    • An inboard power boat for towing water skiers is disclosed which incorporates a wake control device. The boat has a hull configuration in which the stern portion has a flat or semi-flat bottom. The wake control device is comprised of a single flat plate which is pivotally mounted to the stern along the longitudinal axis of the hull. An hydraulic control circuit is provided for pivoting the plate about a transverse axis so that its trailing end moves between raised and lowered positions. The trailing end is moved to a selected position to selectively control the size of the wake as the trailing edge projects to a lesser or greater extent into the stream of water which moves under the hull as the boat moves forward.
    • 公开了一种用于牵引滑水者的内置动力艇,其包括尾流控制装置。 船体具有船体部分,其中船尾部分具有平坦或半平坦的底部。 尾流控制装置包括单个平板,该平板可沿着船体的纵向轴线枢转地安装到船尾。 提供液压控制回路,用于围绕横向轴线枢转板,使得其后端在升高和降低位置之间移动。 尾端被移动到选定的位置以选择性地控制尾流的尺寸,因为随着船向前移动,后缘在较小或更大程度上伸入在船体下方移动的水流中。
