Abstract: A chemical dispensing system for delivering a chemical dose into a water resource is provided herein. The system includes a dispensing housing, a support feature, and an electrical circuit. The dispensing housing includes at least one compartment that is adapted to retain a chemical dose. The compartment is substantially sealable from an ambient environment that is outside of the compartment. The compartment is independently openable and closable to directly expose the compartment to the ambient environment and enable release of contents retained therein in the open position and to substantially prevent release of the contents retained therein in the closed position. The support feature facilitates suspension of the dispensing housing above a surface of the water resource. Opening of the compartment is controllable through the electrical circuit.

Abstract: An instrument to produce ionizing radiation includes a high voltage source of charge and ionizing radiation; a housing filled with insulating gas and containing the high voltage source; an insulator to which the high voltage source is mounted so that the source is spaced from the housing; one or more collector electrodes arranged in the housing such that the high voltage source preferentially discharges to the collector electrode(s); a control system which determines a level of ionization of the insulating gas through the amount of discharge to the collector electrode(s); and/or discharge rate limiting means controllable by the control system to deionize the insulating fluid at a controlled discharge rate and thereby maintain the maximum rate of discharge below a predetermined current. In this way, breakdown events can be inhibited.
