Abstract: An improved soil analysis is provided which provides accurate data representative of actual physical conditions of the soil. Preferably, the method involves first obtaining a core sample of soil having an essentially undisturbed naturally occurring compaction and stratification and subjecting at least a portion of this undisturbed core sample to one or more physical tests such as water permeability, water holding capacity and porosity tests. Thereafter, the sample portion is divided into vertically aligned strata and the latter are individually tested for organic content, silt and clay content and sand content.

Abstract: There is provided an apparatus and method for detecting molten salt in molten metal. A pair of electrically conductive probes are immersed in the molten metal. The probes are connected to an electrical circuit which includes a voltage source and a current detector. The entire immersed portion of one of the probes is coated with an electrically nonconductive porous material which is wetted by molten salt but is not wetted by molten metal. If molten salt is present, the circuit will be completed and a substantial electrical current will flow between the probes, which current is detected by the current detector. If no salt is present, the circuit will not be completed and essentially zero current will be detected.

Abstract: This invention relates to a sampling system for collecting a sample in a septum closed container. It provides for a reservoir of a predetermined volume which captures a sample and it further provides for routing of the captured sample from the reservoir to the septum closed container.
