Abstract: Methods and apparatus are disclosed for substantially improving the energy efficiency of swimming pools having in-floor cleaning systems. Comprehensive data is provided demonstrating the improvement in cleaning capacity realized in a typical prior art pool before and after conversion to the present invention. Methods are disclosed for the reallocation of all or a substantial part of the increase in cleaning capacity toward a proportionate reduction in energy consumption by reducing the run time or operating speed of the pool pump motor while maintaining the same or a higher level of cleaning capacity achieved by the prior art.

Abstract: An improved multi-port water distribution valve is disclosed together with the improved cam mechanism that significantly enhances the efficiency and effectiveness of the valve when used to distribute water to multiple sets of pop-up cleaning heads incorporated into the in-floor cleaning system of a swimming pool. Two forms of prior art distribution valves are disclosed as is the improved cam mechanism that, when used to replace the prior art cam in these devices, significantly improves their performance. Comparative data is provided demonstrating the results achieved with two different prior art valves operated with and without the improved cam. Embodiments of the invention suitable for use in existing six-port and five-port distribution valves are disclosed.

Abstract: One embodiment of an improved ozone generator is comprehensively disclosed by descriptions of computer generated drawings depicting the first commercial version of the invention, which combines the following features: an extruded base with longitudinal channels for receiving connections at distributed points; an extruded cover for detachably engaging the base at each opposing sides and covering a substantial portion of said base; a central baffle that is integral with the cover fro dividing the enclosed volume into a reaction chamber and a circuitry chamber; one or more ultraviolet light sources mounted to connection points on a channel within the reaction chamber; electronic circuitry mounted to connection points on a channel within the circuitry chamber for controlling and transforming an input voltage to drive the light sources; sliding end caps secured to channels in the base for separately covering apertures formed by the ends of the cover and base and for detachably connecting the cover to the base; and
