    摘要: A CMR (Cellular Mobile Radiotelephone) Cell Site includes a foundation for a CMR equipment edifice. The foundation, together with the edifice, rests on a leveled surface. An antenna tower is mounted on the roof of the edifice and is secured by an antenna mounting brace embedded in the roof of the edifice. The antenna is guyed at three elevations along the antenna's height to three points on the foundation. The edifice encloses a 10-inch-square, steel support column, positioned within the edifice directly beneath the antenna mounting brace, for supporting the antenna tower. Four-inch-thick slabs of concrete are inserted between the floor of the edifice and the support column and between the support column and the roof so as to isolate the interior of the building from electrical disturbances such as lightening.

    摘要: 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.

    摘要: 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.

    摘要: 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.
