Apparatus for remote handling of materials

Apparatus for remote handling of materials are described. A closed housing is provided with first and second containers and first and second reservoirs for holding materials to be mixed. The materials are transferable from the reservoirs to the first container where they are mixed. The mixed materials are then conveyed from the first container to the second container preferably by dumping the mixed materials into a funnel positioned over the second container. The second container is then moved to a second position for analysis of the mixed materials. For example, the materials may be ignited and the flame analyzed. Access, such as a sight port, is provided in the housing at the analysis position. The device provides a simple and inexpensive apparatus for safely mixing a pyrophoric material and an oxidizer which together form a thermite type mixture that burns to produce a large quantity of heat and light

An Analysis of Residential Camp Site Structure !or Two Early Archaic Assemblages from Rose Island (40MR44), Tennessee

The site structure of two Early Archaic period assemblages is defined through spatial analysis of artifact and facility distributions at the Rose Island site (40MR44) in the lower Little Tennessee River valley. These assemblages derive from well controlled excavation of deeply buried alluvial deposits attributable to LeCroy (c. 6100-6500 B.C.) and St. Albans (c. 6600-7000 B.C.) temporal units. Spatial patterning is detected using multivariate statistical analysis of formal implement, instant tool, and debitage categories. The observed spatial patterns are interpreted through a comparison with expected spatial patterns generated from an a priori model of hunter-gatherer residential camp activity structure. The results of the analysis allow the proposal of a general model of Early Archaic residential camp site structure. The model identifies activity areas based upon densities and spatial relationships of artifact categories for an assemblage. The reconstructed activity structure describes the location of the family hearth as occurring in front of the opening of the shelter. A wide range of activities are localized around the family hearth. More specialized activities, such as flintworking, hideworking, and the roasting of game, are conducted near the shelter, but apart from the family hearth
