Abstract: The disclosure of the invention is directed to a site survey ground vehicle based apparatus and method for automatically detecting source materials, such as radioactivity, marking the location of the source materials, such as with paint, and mapping the location of the source materials on a site. The apparatus of the invention is also useful for collecting and analyzing samples. The apparatus includes a ground vehicle, detectors mounted at the front of the ground vehicle, and individual detector supports which follow somewhat irregular terrain to allow consistent and accurate detection, and autolocation equipment.

Abstract: A machine is described for accurately elevating and aligning large ceiling panels for placement in an overhead ceiling. The machine includes a frame supported by wheels which permit horizontal transport of the machine between panel receiving and panel placing positions. Elevating outriggers are provided to elevate the frame and wheels at the panel placing location and to partially advance the panel vertically toward placement. A series of elevating stages which are slidably mounted upon guides fixed to the frame elevate the panel to its final elevation for placement. Hydraulic cylinders are provided to elevate the stages. A pair of carriages are provided, mounted on the elevating stages, slidably adjustable along stage frame members, for shifting the panel into transverse and longitudinal alignment for placement. An upper carriage includes a turntable bearing upon which is mounted a base for supporting the panel.
