Abstract: A system for rapid collection of large volumes of dissolved gases from groundwater pumps the water from a large-diameter passage through a small-diameter restrictor passage, and then into a flow-through collection chamber. The small-diameter passage causes a drop in the hydrostatic pressure of the groundwater traveling therein, causing spontaneous ebullition of gas bubbles, which are then collected in the collection chamber. A treatment station within the passages selectively alters the concentration of dissolved gases within the groundwater. Testing reveals that the gases are collected in proportion to their presence in the groundwater, and thus the system allows accurate quantification of concentrations of dissolved gas in groundwater. The system may beneficially be made easily portable, thereby allowing its use in the field, as well as in laboratory settings.

Abstract: This invention provides improvements to worm drives for mechanical power transmission and roller wheels and the worm screws for use in such drives. The principal innovation is utilizing conjugate mesh between the worm screw and the roller wheel by shaping both the surfaces of the threads of the worm screw and the driven surfaces of the roller tips so that they become conjugate surfaces that accomplish the most efficient energy transfer. Previous worm drive approaches have emphasized conforming shapes for the roller tips and the worm screw as well as certain other techniques in an attempt to compensate certain inherent limitations to energy transfer between driving and driven surfaces. This has caused greater energy losses in the gearing mechanism with corresponding decreased power transfer efficiency. The use of conjugate shapes for the roller tips and the driving worm gear surface represents a significant improvement to the concept.
