    • Valve boxes of this invention comprise a housing including an inner chamber that extends axially through the housing from a housing base. The housing chamber includes a diameter that is defined by a housing sidewall surface that extends outwardly from the base, forming a chamber opening. The chamber opening includes a seal surface that is positioned radially inwardly towards the chamber. The valve box further includes a lid that is positioned over the housing chamber opening. The lid includes a concave center section and a seal surface disposed radially therearound. The lid seal surface is positioned radially towards the chamber, and is placed opposite the chamber opening seal surface. An annular seal is interposed between the housing chamber and lid seal surfaces. The chamber and lid seal surfaces are configured generally perpendicular to the chamber opening, such that internal pressure within the chamber causes the concave center portion to impose a radially outwardly directed pressure onto the lid, thereby further compressing the annular seal to ensure a leak-tight seal.
    • 本发明的阀箱包括壳体,该壳体包括从壳体基部轴向延伸穿过壳体的内腔。 容纳室包括由从基座向外延伸的壳体侧壁表面限定的直径,形成腔室开口。 腔室开口包括朝向腔室径向向内定位的密封表面。 阀盒还包括位于容纳室开口上方的盖子。 盖子包括一个凹入的中心部分和一个放置在其周围的密封表面。 盖密封表面径向地朝向腔室定位,并且与腔室开口密封表面相对放置。 环形密封件插入在容纳室和盖密封表面之间。 室和盖密封表面大致垂直于室开口配置,使得室内的内部压力使得凹入的中心部分将径向向外的压力施加到盖上,从而进一步压缩环形密封件以确保密封 密封。

    • An improved sensor array for a mobile vehicle. The vehicle includes a centerline parallel to a vehicle velocity vector. The sensor array comprises a first sensor mounted to the mobile vehicle at a maximum lateral distance from the centerline near a first side of mobile vehicle and a second sensor mounted to the mobile vehicle at a maximum lateral distance from the centerline near a second side of the vehicle opposite the first side. The first sensor transmits a forward pointing first beam and the second sensor transmits a forward pointing second beam, both beams for detecting an object in the path of the vehicle. A plurality of first oblique beams are pointed to intersect the first beam and a plurality of second oblique beams are pointed to intersect the second beam. The oblique beams, in conjunction with the first and second beams form zones of overlapping beam coverage for better localization of objects in the path of the vehicle.
    • 一种用于移动车辆的改进的传感器阵列。 车辆包括平行于车速矢量的中心线。 所述传感器阵列包括安装在所述移动车辆上的第一传感器,所述第一传感器在距离所述移动车辆的第一侧附近的所述中心线的最大横向距离处安装有第二传感器,以及安装到所述移动车辆的第二传感器, 车辆与第一侧相对。 第一传感器传输前向指向的第一光束,第二传感器传输前向指向的第二光束,两个光束用于检测车辆路径中的物体。 多个第一倾斜光束被指向与第一光束相交,并且多个第二倾斜光束指向与第二光束相交。 斜梁与第一和第二波束结合形成重叠波束覆盖的区域,以便更好地在车辆路径中定位物体。

    • An apparatus for determining an area of a surface which is traversed and treated by an object during a unit of time is configured for use with a moveable object that has a first axis of a known length. The object is capable of movement along a second axis and the first and second axes define an angle between them which is other than 0.degree.. A signalling means includes a sensor which may be mounted in a motion-sensing relationship to the object for providing a motion signal when the object moves a distance along the second axis. The motion signal has a predetermined relationship to that distance. A timing means repetitively provides a plurality of timing signals, each sequential pair of which defines an interval of time of known duration. A computing means is coupled to the timing means and to the signalling means for receiving at least one sequential pair of timing signals and at least one motion signal. The computing means thereby initiate a display of the area of the surface which is traversed by the first axis per unit of time and therefore treated as the object moves along the second axis.
    • 一种用于确定在一个单位时间内由对象穿过和处理的表面的面积的装置被配置为与具有已知长度的第一轴的可移动对象一起使用。 该物体能够沿第二轴线移动,并且第一和第二轴线在它们之间形成一个不为0°的角度。 信号装置包括传感器,当传感器沿着第二轴线移动距离时,传感器可安装在与物体的运动感应关系中,以提供运动信号。 运动信号与该距离具有预定的关系。 定时装置重复地提供多个定时信号,每个定时信号的每个顺序对限定已知持续时间的时间间隔。 计算装置耦合到定时装置和信令装置,用于接收至少一个顺序的定时信号对和至少一个运动信号。 因此,计算装置开始显示由第一轴每单位时间穿过的表面的区域,并因此当物体沿着第二轴移动时被处理。
