  • Patent number: 8520352
    Abstract: The present invention provides a multichannel active sensing and switching device featuring a multiple sensing and switching module configured to respond to operational conditions of different load types and provide load type sensor signals containing information about the operational conditions of the different load types, and also configured to respond to controller signals for controlling the operation of the different load types in two or more different protection configurations; and a controller module configured to respond to the load type sensor signals and provide the controller signals in order to control the operation of the different load types in the two or more different protection configurations. The controller module may be programmable and configured to provide a default circuit breaker configuration and a device specific configuration using active intelligence (AI).

  • Patent number: 8347780
    Abstract: The present invention provides a method and apparatus for separating air from a fluid, such as syrup, as the fluid enters a first chamber of a system; passing the fluid from the first chamber to a second chamber via a first device; passing the air from the first chamber to the second chamber via a second device so as to reintroduce the air back into the fluid and form a new fluid mixture having more uniform air bubbles; and discharging the new fluid out of the system.

  • Patent number: 8096320
    Abstract: A pressure regulator includes a body member for regulating pressure of a fluid flowing therein. The body member has one end for receiving the fluid and another end for providing pressure regulated fluid. The pressure regulator has two quick-disconnect devices, each arranged on a respective end of the body member, including a male quick-disconnect device for coupling to a corresponding female quick-disconnect device forming part of a hose or dispenser for providing the fluid or a pump for receiving the pressure regulated fluid; or a female quick-disconnect device for coupling to a corresponding male quick-disconnect device forming part of a hose or dispenser for providing the fluid or a pump for receiving the pressure regulated fluid.

  • Patent number: 6991192
    Abstract: The present invention provide a new and unique macerator assembly or device for coupling and decoupling to a waste disposal port of a holding tank of a recreational vehicle, train, airplane, bus, boat or other portable toilet application for emptying the same. The macerator assembly includes a pump head adaptor and a macerator pump subassembly. The pump head adaptor has means for coupling the macerator device to the waste disposal port of the holding tank, and has a pump head inlet adapter with a garden hose adapter arranged therein for receiving water from a garden hose for flushing the holding tank. The macerator pump subassembly is coupled to the pump head adapter, has an in-take port for receiving waste from the holding tank through the pump head adaptor, has a rotary blade for chopping the waste, and has a discharge port for discharging the waste to a suitable discharge waste repository.
