Abstract: A torque transmitting ball joint can include a spherical ball, a stem extending from the spherical ball, one or more pins coupled to the spherical ball, and a socket. The socket can define an opening sized to contain the spherical ball within the socket and one or more slots sized to accommodate a pin of the one or more pins. The one or more pins can be contained by the one or more slots and can translate within the slot as the spherical ball rotates relative to the socket about a pivot center. At least one of the one or more pins can abut a sidewall of its slot and transmit torque from the stem to the socket via the spherical ball when the stem and spherical ball rotates relative to the socket.

Abstract: A surface maintenance machine includes a body, a surface maintenance tool coupled to the body, processing circuitry supported at the body, and a light projection mechanism supported at the body and coupled to the processing circuitry. The light projection mechanism includes a light housing, a light emitting element within the light housing, and a projection lens that is configured to focus light emanating from the light emitting element. The light projection mechanism is configured to project light onto a ceiling surface that is above a floor surface along which the surface maintenance machine is configured to perform a surface maintenance task using the surface maintenance tool.

Abstract: A system and method for dispensing a treatment fluid is provided. The system includes a surface maintenance machine, a fluid reservoir, an air blower, and one or more fluid dispensing systems. The one or more fluid dispensing systems each include one or more nozzles in fluid communication with the air blower. The air blower generates an air pressure and dispenses air through the one or more nozzles while the treatment fluid is dispensed through the one or nozzles. The dispensing of air and treatment fluid dispenses the treatment fluid in a mist, fog, or spray to a surface. A method for dispensing a treatment fluid is also provided. The method includes generating an electrically charged treatment fluid and dispensing the electrically charged treatment fluid from the one or more nozzles to a surface.

Abstract: Embodiments include a surface maintenance machine, comprising a maintenance tool chamber comprising a first side, a second side, a third side and a fourth side. A rotary broom is housed in the maintenance tool chamber and substantially enclosed by the first, second, third and fourth sides thereof. The rotary broom sweeps particulate from the surface. A vacuum system generates vacuum for drawing particulate swept by the rotary broom. The vacuum system is positioned proximal to the first side. A skirt assembly extends substantially around the second, third and fourth sides of the maintenance tool chamber. The skirt assembly has a vacuum passage defined therein and in fluid communication with the vacuum system to direct air flow into the vacuum passage, thereby drawing particulate into the vacuum passage and preventing particulate accumulation at portions of the second, third and fourth sides that are distal to the vacuum system.

Abstract: Embodiments include a waste recovery system for a floor surface maintenance machine. The waste recovery system comprises a squeegee assembly having a squeegee frame, a squeegee retainer extending below the squeegee frame and a reservoir integrally defined in the squeegee retainer. The reservoir can have an inlet passage proximal to the floor surface, an outlet passage fluidly coupled to the fluid suction path and leading to the waste recovery tank, and a fluid trap portion positioned between the inlet and outlet passages. The fluid trap portion can retain backflow waste in the fluid suction path. The reservoir is positioned at a clearance distance from the floor surface in a direction normal to the floor surface such that the reservoir forms the lowest portion of the waste recovery system in the direction normal to the floor surface.

Abstract: An electrolytic cell is provided. The cell includes a housing having a liquid inlet and a liquid outlet outlet, an anode and a cathode positioned within the housing and defining a reaction chamber therebetween, and a liquid flow path, from the liquid inlet to the liquid outlet, which passes through the reaction chamber. A transition duct is positioned at the liquid outlet and has a duct inlet, a duct outlet and a transition section along which internal side walls of the transition section converge along the liquid flow path to define a smooth transition from a first cross-sectional area to a second cross-sectional area of the transition duct. The first cross-sectional area is at least two times greater than the second cross sectional area.
