Abstract: A method for production and storage of hypochlorous acid is disclosed. The method comprises using high purity water achieved by a combination of softening and reverse osmosis steps. The shelf life is further improved by storing the hypochlorous acid in opaque PET bottles or Nylon/PE bags or nylon bags in a box. Solutions stored in opaque PET bottles exhibit the best stability. Anticipated uses of the extended life hypochlorous acid solution include sanitizer for food contact and non-food contact surfaces, a streak-free cleaner for smooth surfaces and a cut flower life extender. Other biocide uses include water treatment in oil and gas production, cooling tower, lazy river and swimming pools, process water distribution systems, drinking water, portable humidifier, fish tanks and treatment of metalworking fluids and lubricants.

Abstract: A bicycle transmission has drive pedals connected through a pedal shaft disposed in a pedal shaft hub on a bicycle frame. The shaft is selectively engageable with a series of gear pawls which are positioned to selectively engage one of a series of gears disposed about the pedal shaft. The gears are selectively engaged with an output sprocket meshed to a rear wheel sprocket. The pedal shaft includes a series of angled slots therein, in which a cam follower pin is disposed. The cam follower includes an actuator arm to cause one of the gears to engage the pedal shaft. The slots are sized so that reverse pedal rotation will cause the cam follower to axially actuate about the pedal shaft to cause disengagement and engagment of the gears.
