Abstract: Solution production devices, systems, and methods. The system includes a base portion configured to receive a vessel containing a liquid. Upon the base portion receiving the vessel, liquid is transferred from the vessel and into the base portion where it undergoes an electrochemical reaction to produce a cleaning solution. The cleaning solution is then circulated back into the vessel.

Abstract: To solve problems in a conventional cap opening apparatus wherein it is uneconomical and requires a large storage space to prepare dedicated cap opening apparatus to open the caps of various cans and bottles sealed by different systems and, in a conventional cap opening apparatus having cap opening functions for different applications at both ends of a single output shaft, when one of the functions is set to develop a proper capacity, the other develops an excessive or a sufficient capacity. This cap opening apparatus comprises a speed changing portion 50 having a gear train for matching the output of a motor to the purposes of a plurality of output shafts and an output power changing section for the gear train. Since the speed changing portion transmits optimum torques to the output shafts 133 and 140 and can selectively drive only one output shaft through the output power changing section, safety can be increased.
