In order to safely and conveniently assemble and service new design spring brake actuators having power springs located in the middle of the actuator, the actuator’s rear chamber cover must be able to withstand high localized forces from tools such as power spring compression rods. The midsole includes a plurality of cells that extend generally upward from a generally flat support structure and provide the ability to selectively attenuate the ground reaction forces that result when one engages in activities associated with the application for which the shoe midsole is designed. The resisting member is aligned with a pin of the connector and attached to a first end of the connecting member. The filtering section, black signal generating section and tone processing section execute processes in accordance with the recognition signal from the third recognition section. This invention further relates to apparatus and methods for growing microbes on-site at a wastewater treatment facility, and for economically inoculating sufficient microbes to solve various treatment problems rapidly. The other colorant is selected from a pigment, a dye, and combinations thereof.
