Abstract: An apparatus for cleaning floors which recycles waste heat and water to provide greater efficiency. An internal combustion engine is used to power the apparatus. Heat from the engine's lubricant is used to heat the wash solution applied to the floor. Heat from the engine's cooling air, radiator, and catalytic converter is used to dry the cleaned floor. A drying brush is also used to accelerate drying. Used rinse water is recycled for use as wash solution. Exhaust from the engine is used to preheat the floor to be cleaned. The engine may be used to propel the apparatus.

Abstract: An apparatus for use on a surface and responsive to an operator. A head assembly is adapted to carry a device for engaging the surface. An actuator raises and lowers the head assembly relative to the surface. A position control responsive to operator input indicates a head position of the device relative to the surface or range of head positions of the device relative to the surface. The head position or the range of head positions indicates a distance or range of distances, respectively, between the device and the surface. A controller responsive to the position control selectively actuates the actuator to maintain the device in the head position or within the range of head positions as indicated by the position control. As a result, a repeatable position or range of positions of the brush head is obtained, the relative engagement between the head assembly and surface is controlled and the treatment of the surface by the head assembly is controlled.

Abstract: A system for monitoring carbon monoxide in an environment which includes an apparatus emitting carbon monoxide, such as an internal combustion engine. A carbon monoxide sensor measures a concentration of carbon monoxide in the environment and provides an electrical signal to a processor that is representative of the measured concentration of carbon monoxide. The processor determines the concentration of carbon monoxide corresponding to the electrical signal, provides an output signal at or above predetermined carbon monoxide concentration thresholds, calculates an estimated carboxyhemoglobin level for the operator corresponding to the carbon monoxide concentrations calculated over time, and provides an output signal at or above predetermined carboxyhemoglobin thresholds. The signals are then received by one or more devices which provide textual, visual, and/or audible warnings indicating that environmental concentrations of carbon monoxide have caused a predetermined warning threshold to be met or exceeded.

Abstract: A solenoid valve and timing module kit for use with a floor treating apparatus. The apparatus includes a reservoir for holding a cleaning solution, a flow control valve, a head assembly adapted to carry a floor treating device, a fluid flow line for delivering the liquid supply to a supply point adjacent to the floor treating device, an operator control, and a timing module for continuously opening and closing the flow control valve in response to the operator control.

Abstract: An apparatus for use on comprising a vehicle adapted to move across a surface and responsive to an operator. A head assembly connected to a support on the vehicle is adapted to carry a device for engaging the surface. An actuator on the vehicle raises and lowers the head assembly support relative to the surface. A position control responsive to operator input indicates a head position of the device relative to the surface or range of head positions of the device head assembly relative to the surface support. The head position or the range of head positions indicates a distance or range of distances, respectively, between the device and the surface. A controller responsive to the position control selectively actuates the actuator or maintain the device head assembly in the head position or within the range of head positions as indicated by the position control.
