Abstract: A floor cleaning machine is provided. The floor cleaning machine includes a solution tank for a cleaning solution. A pre-canister sensor receives the cleaning solution and measures the concentration of any dissolved solids. A canister assembly receives a portion of the cleaning solution from the pre-canister sensor and dissolves portions of a solid chemical form into the cleaning solution thereby forming blended droplets. The canister assembly has a spray nozzle positioned vertically above the solid chemical form. A post-canister sensor receives a mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. The post-canister sensor measures the concentration of any dissolved solids within the mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. A comparison of the baseline and post-canister measurements outside of a desired range results in replacement of the solid chemical form.

Abstract: A laser system capable of producing a stable and accurate high-power output beam from one or more input beams of corresponding laser sources comprises one or more optical elements configured to receive the input beams wherein at least one of said one or more optical elements is made of high purity fused silica.

Abstract: A floor cleaning machine is provided. The floor cleaning machine includes a cleaning head configured for cleaning a floor surface with a cleaning solution. A collection mechanism is configured to collect used cleaning solution following use by the cleaning head. A conduit fluidly connects the collection mechanism with a recovery tank. The conduit is configured to convey a flow of the used cleaning solution from the collection mechanism to the recovery tank. A defoaming system is positioned proximate the recovery tank and includes a solid chemical defoaming form. The solid chemical defoaming form is configured for dissolution within the flow of the used cleaning solution. The flow of the used cleaning solution is directed over the solid chemical defoaming form and into the recovery tank.
