Patent number: 8814533Abstract: Flood water removal systems including a motor, a vacuum generating device, a discharge pump, and a vacuum tank can be efficiently arranged to be transversely mounted to a vehicle. Certain flood water removal systems can include a supercharger driven by the engine to generate vacuum. The systems can include a valve to prevent collapse of a vacuum tank and maintain a predetermined vacuum pressure without varying the speed of the motor. The systems can also include a two-stage exhaust that blends exhaust from the blower with motor exhaust in a silencer to reduce noise generation for operation in residential or other noise-sensitive settings. The systems can also include a vacuum tank comprising a noise reduction baffle to further reduce noise generation.Type: GrantFiled: February 23, 2011Date of Patent: August 26, 2014Inventors: Mark Exner, Bill Exner, Aaron S. Bingle, Eric A. Bingle, David Cody Sizemore

Patent number: 8800167Abstract: A pneumatic inflation device disposed within the sole of a shoe and comprising a pump with integral air release valve and which is entirely within the sole, a pump actuator which is entirely within the sole when not in use, and an inflatable bladder which is entirely within the sole and is operatively connected to the pump. Such a device can include a mechanism to lock the pump actuator within the sole such that the mechanism's cap is flush with the outer wall of the sole and finger-operable to allow the shoe-wearer to easily operate the inflation device and release air therefrom.Type: GrantFiled: September 16, 2010Date of Patent: August 12, 2014Inventor: Harold S. Doyle

Publication number: 20140205473Abstract: Dispensers, refill units and pumps are disclosed herein. The refill units include a container secured to a pump. Some exemplary refill units for dispensers include a container for holding a liquid and a post seal pump. As the post seal pump operates, a piston moves up and down over the pump seal. When the piston shaft is in a first position, fluid flows into the pump chamber and one or more apertures through the piston shaft are sealed off by the post seal. When the piston shaft is in a second position, the piston engages a wall of the pump chamber and the one or more apertures are away from the post seal to provide a fluid path from the pump chamber to the interior of the hollow piston shaft and is dispensed through an output.Type: ApplicationFiled: January 23, 2013Publication date: July 24, 2014Applicant: GOJO Industries, Inc.Inventors: Nick E. Ciavarella, Jonathan E. Fawcett, Aaron D. Marshall

Patent number: 8783663Abstract: Humidifying apparatus includes a humidifier for emitting moist air into an external environment, and a fan assembly for generating an air current within the external environment for conveying the emitted moist air away from the humidifier. The fan assembly includes a device for creating an air flow and a nozzle including an interior passage for receiving the air flow and a mouth for emitting the air flow. The humidifier is located behind nozzle, the nozzle extending about and defining an opening through which both air from outside the nozzle and the moist air emitted from the humidifier are drawn by the air flow emitted from the mouth.Type: GrantFiled: December 18, 2012Date of Patent: July 22, 2014Assignee: Dyson Technology LimitedInventors: Nicholas Gerald Fitton, John Scott Sutton, Peter David Gammack, James Dyson

Patent number: 8764408Abstract: A pump system selectably and dynamically controls the flow rate of a fluid being delivered to a patient's body over a wide range of flow rates. The pump system includes an infusion tubing, a pumping mechanism, a motor drive assembly in mechanical communication with the pumping mechanism, a user input control, and an electronic controller in electrical communication with and at least partially controlling the motor drive assembly. The electronic controller include a digital signal processing controller in electrical communication with the motor drive assembly that is configured to receive a signal from the user input control and to cause power to be supplied to the motor drive assembly in response at least partially to the signal from the user input control. The pump system may selectably deliver fluid at rates from about 1 milliliter per hour to at least about 3000 milliliters per minute.Type: GrantFiled: January 25, 2013Date of Patent: July 1, 2014Assignee: Smisson-Cartledge Biomedical LLCInventors: Hugh F.
