Abstract: A security apparatus for preventing opening of a hinged door from the inward swinging side, the door being received in a door frame having a door facing on the outward swinging side, the door including a door knob extending from the outward swinging side, the door knob having a shaft portion, the apparatus having a web portion having first and second spaced ends, a first flange portion depending in a first direction from the first end of the web portion and generally transversely thereto, the first flange portion having a first notch for receiving the shaft portion, a second flange portion depending in the second direction from a second end of the web portion and generally transversely thereto, the second flange portion having an inner surface which faces in a direction toward an imaginary plane passing through the first flange portion transversely to the web portion such that when the door is closed and the shaft position of the door knob on the outward swinging side is received in the notch of the first fla

Abstract: A CMR (Cellular Mobile Radiotelephone) Cell Site includes a structurally compact and easily transportable 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.

Abstract: 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.
