Abstract: A flow rate component, such as a bypass valve with a motorized actuator, a variable speed circulation pump, or both, is controlled in realtime by an automatic controlled to regulate water flow rate through a swimming pool heater, such as a heat pump, to optimize heat transfer, minimize energy consumption, and improve life spans of components of the swimming pool circulation, filtering and heating system.

Abstract: A salt water chlorinator assembly along a closed loop water circuit incorporates a chlorinator cell subassembly and a flow switch subassembly into respective fluidly connected chlorinator assembly housing interior portions. The chlorinator cell subassembly includes an electrolysis cell controlled by a chlorinator printed circuit board. The flow switch subassembly includes a flow sensor mounted upon a printed circuit board assembly (PCBA). A flow switch cable selectively attaches to a PCBA connector. Water flow rate data generated by the flow switch sensor, communicated via an external controller to a smart circulation pump, is used to enable automatic adjustment of the pump speed based upon the flow rate data. The external controller may further alert an end user of undesirable flow rate deviations due to a condition (e.g. a clogged pump/skimmer basket and/or dirty filter) along the closed loop circuit requiring attention.

Abstract: A pool maintenance system for maintaining desired characteristics of a body of water in fluid communication therewith, includes a chlorine generator having an integral power supply input, a water circulation pump in fluid communication with the body of water and with the chlorine generator via a series of water conduits, and a heat pump in fluid communication the water circulation pump. The water circulation pump and/or the heat pump incorporate an integral power supply/transformer functioning as a single shared power source communicatively integrating the chlorine generator with the respective water circulation pump and/or heat pump. A wired and/or wireless interface is provided electrically connected to the power supply and transformer integrated with the respective water circulation pump and or heat pump.

Abstract: A tube and shell heat exchanger is formed by a shell enclosing an internal sidewall which in turn receives an internally located flow controller outer and inner heat exchange cavities are formed between the outer shell and the internal shell and the internal shell and the flow controller, respectively. Helical convolutions of the conduit are provided in each of the heat exchange cavities for counter concurrent flow of fluid medium from one cavity to another. A bottom wall closes off the outer shell.

Abstract: Calcareous materials which are very purified residues of corallinaceae particulary Lithothamnium corallioides have unusual therapeutic properties including treatment of conditions created by failure of immune regulation, for example rheumatoid or osteo arthritis, osteoporosis and other conditions involving pH control. A method for purification is provided. Also provided are compositions of the residues together with fatty acids, glycerides, polyglycols and emulsifiers. Particularly advantageous are compositions of the residues and medium chain triglycerides.

Abstract: A tube and shell heat exchanger having a transversely oriented inlet port and a spirally coiled heat transfer tube contained within an arcuate chamber created by an internal baffle in which the water to be conditioned travels along a helical pathway in which the flow has minimized water depth and high turbulence. The tube and shell heat exchanger maximizes heat transfer capability in a relatively easy to assemble design to make feasible the use of a higher cost material for the tubing such as titanium in a wide range of applications.
