  • Patent number: 9356387
    Abstract: A connector assembly comprises front and rear connector bodies, a wire grommet with wire passages, and a nut. Tightening the nut forces a rearward portion of the grommet into a tapered segment of a passage through the rear connector body, thereby radially compressing the grommet and sealing the wires passing therethrough.

  • 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: 7472430
    Abstract: A laminar flow waterfall in the form of a single or multiple streams of water, each exiting from a nozzle in the top edge of a spa. The laminar water stream is created by a venturi nozzle located in a plenum chamber. The inlet side of the nozzle has a cover with a plurality of small holes forcing the water flow to enter the nozzle as laminar flow. A flow divider inside the venturi nozzle, from the inlet to the restriction of the nozzle, maintains the flow laminar through the nozzle. Light is injected into the flow divider at the inlet and is carried by the flow divider to be injected into the water flow at the restriction of the nozzle.

  • Patent number: 7219690
    Abstract: A two-stage fluid pressure control valve has five components. An inlet socket with separate fluid flow orifices sealably engages an outlet socket which also has separate fluid flow orifices. A pressure check piston having a fluid flow orifice along its longitudinal central axis slidably engages the inlet socket and the outlet socket. A spring located along the central axis of the outlet socket biases the pressure check piston in an open position, allowing fluid to flow through all orifices. Fluid flow through the control valve may impact the pressure check piston to overcome the spring force, moving the pressure check piston to a closed position, whereby fluid flows only through the orifice in the pressure check piston.

  • Patent number: 7140051
    Abstract: A dry suction fitting assembly is provided for drawing water from a spa, whirlpool bathtub or other suitable water tub to a pump, featuring a suction body for arranging in relation to a wall of the spa, whirlpool bathtub or other suitable water tub. The suction body is arranged in relation to a wall of the spa, whirlpool bathtub or other suitable water tub, has a suction inlet for coupling to the pump, and has an internal surface with an equilibrium tube arranged therein with three openings, a first opening that acts as a water flow inlet, a second opening that is open to the atmosphere via a connection hose or other suitable connection device and that is filled with water during normal operation, and a third opening that is a safety orifice coupled to the suction inlet. During normal operation water flows from the first opening, through the equilibrium tube, and out the third opening.
