  • Patent number: 11101088
    Abstract: Applicant has created systems, methods, and apparatuses for controlling the power supply of a vacuum cleaner motor. The systems and apparatuses include pressure taps to detect a pressure differential within a vacuum cleaner, a float that adjusts depending on an amount of liquid stored, and a power switch that toggles based on the pressure differential created by the position of the float. Alternatively, the float can be replaced by an air chamber so that the pressure differential is created by liquid rising above the volume of air trapped in the chamber. The method can include interrupting the current supplied to an electrical circuit of a power switch based upon a pressure differential created within the vacuum. By controlling the power supply to a vacuum cleaner motor based on a pressure differential created by the amount of liquid stored within the vacuum cleaner, the vacuum cleaner can automatically disable the vacuum cleaner's motor as the vacuum approaches its maximum liquid capacity.

  • Patent number: 9604343
    Abstract: A motor, a reservoir, a recovery basket, an internal hose, an external hose, a power switch, baffle with injection nozzles and floats, a sanding head, an extended sanding head, and a corner sanding head comprises a hydro-filtration unit with a sanding heads for drywall work. The sanding heads may be used to sand drywall and simultaneously draw the dust out of the air as it is created through the sanding process. The hydro-filtration prevents dust from being released into the air. Within the reservoir, the internal hose connects at one end to the motor and at the other to the floating dust injector unit and the injection nozzles. The external hose connects the sanding heads to the motor.

  • Patent number: 9554682
    Abstract: A vacuum cleaner (1) comprises an inlet (13), an outlet, a fan (14) for creating a flow of air through the vacuum cleaner (1) by drawing air to be cleaned through the inlet (13) into the vacuum cleaner (1) and by exhausting air through the outlet outwardly of the vacuum cleaner (1) and a separator (15, 41). The separator (15, 41) is rotatably arranged around an rotation axis (21), for creating, during use, a column of rotating air to separate at least a portion of the airborne particles (10) from the flow of air. The separator (15, 41) includes a number of vanes (25, 44) for the creation of the column of rotating air, wherein each vane (25, 44) is provided with a leading face (26) and a trailing face (27). The leading faces (26) of the vanes (25, 44) are inclined with respect to the rotation axis (21) for conveying the airborne particles (10) at least in an axial direction.

  • Patent number: 9524484
    Abstract: A method for handling water and oil automatically monitors and schedules the trucking of waste water between a disposal site and multiple well sites. In some examples, the method automatically detects the presence of a tanker truck at a well site and/or at the disposal site and records the truck's arrival and departure times. In some examples, the method monitors the changing level of waste fluid collected in a waste fluid storage tank at the well site and thereby determines the volume of waste fluid transferred from the tank to the truck. In some examples, the method also estimates the volume of waste fluid transferred from the well bore into the tank while the truck is withdrawing fluid from the tank. In some examples, the method automatically generates and posts online billing information and regulatory reports associated with waste water trucking, waste water disposal and oil reclaiming.

  • Patent number: 9439543
    Abstract: A compact, self-contained servicing apparatus for onboard lavatories on private aircraft and other vehicles comprises a reservoir container with a lid coupled to a flexible hose bearing a standard lavatory clean-out coupling on its opposite end. The coupling mates with a clean-out port beneath the lavatory of the vehicle. The hose permits contents of the onboard lavatory to flow under gravity into the container. The device includes a rinse bucket for pouring rinse water through the lavatory and for refilling the lavatory with disinfect and fluid. The device also optionally contains gloves, goggles, towels and other supplies used in the self-service process, and a second lid seals the container for transporting lavatory effluent to a disposal area. In one embodiment, the components of the apparatus nest within the container to form a service kit that stores onboard the vehicle when it is not in use.
