Hydrocyclone/Filter for Concentrating Biomarkers From Soil

This apparatus could detect biomarkers or chemical waste in soil. The hydrocyclone- filtration extractor (HFE), now undergoing development, is a simple, robust apparatus for processing large amounts of soil to extract trace amounts of microorganisms, soluble organic compounds, and other biomarkers from soil and to concentrate the extracts in amounts sufficient to enable such traditional assays as cell culturing, deoxyribonucleic acid (DNA) analysis, and isotope analysis. Originally intended for incorporation into a suite of instruments for detecting signs of life on Mars, the HFE could also be used on Earth for similar purposes, including detecting trace amounts of biomarkers or chemical wastes in soils.

Linear Motors and Actuators Meets Automation Needs

Linear motors and actuators are now cost-competitive with ball screws and belt drives and offer distinctly superior agility and bandwidth for advanced positioning applications. New micromotors and actuators are helping to automate tasks not previously feasible. Direct linear drives are increasingly replacing servo-controlled pneumatic cylinders, contributing reliability and controllability, free from the cost, noise, and upkeep of air compressors.
