    • CMR (Cellular Mobile Radiotelephone) equipment is disposed in a configuration that facilitates both transportation to a cell site and, at the site, rapid installation of the CMR equipment and accompanying antenna tower. The CMR equipment incorporates a foundation that includes (i) a rectangular center structure formed from a front horizontal section, a rear horizontal section, a left vertical section, and a right vertical section, and (ii) a nose structure attached to and extending vertically from the front horizontal section. A self-contained CMR equipment edifice, having four walls, a floor and a roof, is secured to the rectangular center structure of the foundation by a plurality of flanges positioned at predetermined locations on the edifice and affixed to both the foundation and walls of the edifice. Several antenna tower sections are attached to the edifice by a number of identical antenna mounting assemblies. Each of the antenna mounting assemblies comprises a bracket attached to a wall of the edifice and a pipe strap removably affixed to the bracket. Left and right crossmember sections are attached to walls of the edifice by the above-mentioned flanges. The left and right crossmember sections are, in turn, respectively secured to top plates of the left vertical and right vertical sections, thereby securing the edifice to the foundation. Left and right leg sections, pivotably attached to opposite ends of the rear horizontal section, are folded into proximity with, respectively, the left vertical section and the right vertical section. In a preferred embodiment, the rear horizontal section includes a left bracket plate pair, disposed at the left end of the rear horizontal section, for accommodating the pivotable attachment of the left leg section. A right bracket plate pair is similarly disposed at a right end for the right leg section.
    • CMR(蜂窝移动无线电话)设备被布置成便于运输到小区站点,并且在现场快速安装CMR设备和伴随的天线塔。 CMR设备包括一个基础,其包括(i)由前水平部分,后水平部分,左垂直部分和右垂直部分形成的矩形中心结构,以及(ii)连接并垂直延伸的鼻部结构 从前面的水平部分。 具有四个墙壁,地板和屋顶的独立的CMR设备建筑物通过位于大厦的预定位置处的多个法兰固定到基座的矩形中心结构,并且固定到基座和墙壁上 大厦。 几个天线塔段通过多个相同的天线安装组件连接到建筑物。 每个天线安装组件包括附接到建筑物的壁的支架和可拆卸地固定到支架的管带。 左右交叉部分通过上述法兰连接到大厦的墙壁。 左和右横梁部分又分别固定在左垂直和右垂直部分的顶板上,从而将大楼固定在基础上。 可枢转地附接到后水平部分的相对端的左腿部分和右腿部分别分别折叠成左垂直部分和右垂直部分。 在优选实施例中,后水平部分包括设置在后水平部分的左端的左托架板对,用于容纳左腿部分的可枢转附件。 右支架板对同样地设置在右腿部分的右端。

    • An apparatus for reclaiming no-bake foundry sand is provided, in which a fluidized stream of pneumatically conveyed particles of no-bake coated sand grains traveling at velocity sufficient for transport is discharged against a target to fracture the no-bake rigid coatings from the sand grains on impact. Certain of the fractured coatings are removed and the sand grains along with any remaining fractured coating particles are directed through a passageway having a fluidizing air stream induced therein. The air stream entrains and carries off the fractured coatings and the fine sand grains so that only sand grains of desired particle size pass through the air stream for subsequent reuse. Advantageously, the velocity of the air stream is controlled by regulating the cross-sectional area of the passageway at the point at which the air stream is induced.
    • 提供了一种用于回收无烘烤铸造砂的设备,其中以不足以运输的速度行进的无烘烤涂覆的砂粒的气动输送颗粒被排放到靶上,以从砂中破坏无烘烤的刚性涂层 谷物对冲击。 去除某些断裂的涂层,并且砂粒以及任何剩余的断裂涂层颗粒被引导通过其中引入流化气流的通道。 空气流夹带并带走破裂的涂层和细砂粒,使得只有所需粒度的砂粒通过空气流才能再次使用。 有利地,空气流的速度通过调节在引导空气流的点处的通道的横截面面积来控制。

    • A tool for turning a screw, nut, bolt or other rotatable workpiece includes a bottom housing carrying a workpiece engageable part and, above the housing, a handle engageable by the hand of a user. The handle is axially and angularly shiftable relative to the housing and is angularly connectable to the housing through both a torque spring and through sets of angular stops on the housing and on the handle which stops are brought into and out of engagement with one another as the handle is shifted axially relative to the housing. The tool may be used as an ordinary screw driver or wrench whereby hand torque is transmitted directly from the handle to the housing, as a torque measuring tool whereby hand torque is transmitted from the handle to the housing through the torque spring, and as a preloaded tool whereby a given amount of torque is loaded into the tool prior to application to the workpiece and then, after application of the tool to the workpiece, is released and used to rotate the workpiece without the handle being rotated by the user.
    • 用于转动螺钉,螺母,螺栓或其它可旋转工件的工具包括承载工件可接合部分的底部壳体,并且在壳体上方具有可由使用者的手接合的手柄。 手柄相对于壳体轴向和角度地移位,并且通过扭矩弹簧和壳体上和手柄上的一组角度止挡件可角度地连接到壳体,该止动件彼此之间被引入和脱离接合 手柄相对于壳体轴向移动。 该工具可以用作普通螺丝刀或扳手,其中手扭矩从手柄直接传递到壳体,作为扭矩测量工具,由此手扭矩通过扭矩弹簧从手柄传递到壳体,并且作为预加载 工具,由此在施加到工件之前将给定量的扭矩装载到工具中,然后在将工具施加到工件之后被释放并用于旋转工件,而不会使用者旋转手柄。
