Abstract: A pneumatic reciprocating fluid pump for pumping a fluid includes at least one check valve assembly that includes a check valve body insert, a ball within the valve body insert, and an annular sealing ring member disposed within a seat ring receptacle. The sealing ring member has dimensions smaller than corresponding dimensions of the seat ring receptacle, such that the sealing ring member is capable of moving within the seat ring receptacle. The ball is configured to slide back and forth between a first position and a second position within the check valve body insert responsive to forward and reverse flow of fluid therethrough. In one position, the ball is seated against the sealing ring member and prevents reverse flow of the fluid through the check valve assembly, and forward flow of the fluid through the check valve assembly is enabled when the ball is in another position.

Abstract: A water level detection system in a pool, spa, fountain or water feature, the water level detection system being provided with a tap line coupled to a plumbing line on a suction or supply side of a filtration system and admitting water from the pool, spa, fountain or water feature such that the change in level of the water in the tap line corresponds to a change in level of the water in the pool, spa, fountain or water feature. A sensing module has at least one sensor for detecting the height of a column of water or the pressure of a column of air in the water tap line. A controller is coupled to the sensing module and adapted to collect the data from the sensors that detect changes in the level of the water level of the pool, spa, fountain or water feature, communicate the detection of such a change, and report such a change to initiate addition or removal of water from the pool, spa, fountain or water feature body of water to adjust the water level in the body of water to a set point.

Abstract: A seed treatment composition which efficiently applies a seed treatment material such as a bacterium or plant protein to a seed by using a talc-based carrier material. The seed treatment composition generally includes a carrier material which is mixed with a seed treatment material and applied to a seed such that the carrier material and seed treatment material both adhere to and uniformly coat the exterior surface of the seed. The carrier material will generally include talc which mixes with the seed treatment material and adheres to the exterior of the seed. The seed treatment material may comprise any solid, particulate material which would benefit a seed, such as an inoculant, bacterium, plant proteins, insecticide, and/or fungicide.

Abstract: A pH balancing solution dispenser having an upper body portion and a lower dispenser body portion.

Abstract: A system for controlling a load control relay (LCR) supplying power to a thermostat of a heating, ventilating, and air conditioning (HVAC) system includes a controller programmed to maximize the amount of time that a load of the HVAC system may receive power. The controller operates by measuring a thermostat delay time of the thermostat and modifying cycle shed and restore times for controlling the LCR based on the measured thermostat delay time. By controlling the LCR according to the modified cycle shed and restore times, the controller compensates for the thermostat delay time, and the load is able to be active for a longer period of time than it otherwise would be when operating under demand-response controls.
