Abstract: A battery water level detector assembly for a battery operated device comprising a control unit configured for use with a battery of the device, with the control unit including an electronic sensor operative to provide a signal indicative of the water level within the battery and with the control unit being operative to provide a control signal in response thereto. The electronic sensor is operative to detect when a visual indicator operably connected to the battery provides a display that the water level within the battery has decreased below a desired level. The control signal in turn may be used to generate an alert, including a remotely transmitted alert, and/or alter operational functionality of the battery operated device.

Abstract: A chemical metering system for providing efficient access and replacement of chemical metering devices. The chemical metering system generally includes a chemical injector, a first tube fluidly connected to the chemical injector, a second tube adapted to be fluidly connected to a chemical supply, a releasable tube coupling removably and fluidly connected to the first tube and the second tube, and a metering device is adapted for controlling a flowrate of liquid chemical into the chemical injector from the chemical supply. The metering device is accessible for repair or replacement by removing the releasable tube coupling from either the first tube or the second tube for efficient access and replacement of the metering device.

The elbow has a pressure channel and a suction channel there through. The length of the apparatus from the elbow to the housing is short enough to be passed into the bunghole of a vessel, e.g. a wine barrel, while racked. A flexible suction hose is connected to a suction line in the apparatus for removing spent cleaning fluid from within the vessel.

Abstract: A tire dressing system for efficiently and accurately applying tire dressing to vehicle tires. The tire dressing system generally includes a support unit, a spray unit movably positioned within the support unit, an actuator unit connected to the spray unit, a tire sensor to determine the size of a vehicle tire, and a tire position sensor to determine the location of the vehicle tire.

After the size of the vehicle tire is determined, the proximity of the hollow cone nozzle is adjusted to apply the desired spray pattern to the sidewall. The hollow cone nozzle then applies the dressing to the sidewall of the vehicle tire as the vehicle moves by the spray unit.
