  • Patent number: 6851664
    Abstract: A self-relieving choke valve system for a carburetor of a combustion engine automatically opens a choke valve after a successful engine start up and permits the choke valve to automatically close when the engine is shut down. The self-relieving choke valve system is preferably passive in nature and preferably self contained to the carburetor. It has a vacuum motor which preferably receives a vacuum signal from a vacuum source derived from the operating engine to open the choke valve. A lost motion linkage of the self-relieving choke valve system permits the choke valve to fluctuate between a closed position and a slightly open engine start up position without any intervention by the vacuum motor while the engine is being started.

  • Patent number: 6824125
    Abstract: An apparatus, and its method of operation, are described that allow for the production of gas-filled vortex rings in a host liquid. A source of gas under pressure is connected via a tube to the inlet of a regulation valve whose outflow is connected via a similar tube to an accumulator volume. The accumulator has an outlet that feeds the gas in the accumulator to an electrically operated solenoid valve that is normally closed. The outlet of this valve leads to a nozzle that protrudes upwards into a vessel containing the liquid in which it is desired to form the rings. Upon receiving an electrical pulse of known duration, the solenoid valve opens for that duration and allows a momentary pulse of gas to flow from the accumulator into the nozzle. If the pulse duration is correctly set, a vortex bubble forms at the exit of the nozzle which self-organizes into a defined ring once the gas flow ceases.

  • Publication number: 20040124548
    Abstract: The water carbonation method and apparatus of the present invention consists of a square mixer within a carbonated chamber. The mixer is partially filled with water. Carbon dioxide is then added above the level of water. A rotating member attached to the mixing motor then mixes the water and carbon dioxide to from a carbonated solution. Varying the time for which the carbonation operation is carried on may vary the degree of carbonation.

  • Patent number: 6601832
    Abstract: The invention relates to a device for sucking air and mixing it with a liquid fuel flowing in a tubular flow duct. The device has a liquid intake duct (3) and outlet duct (4) and between them a throttle section (1), which forms a substantially reduced flow cross-sectional area for the flow. The throttle section has for the flowing liquid fuel at minimum one throttle duct (6a, 6b), which extends with substantially the same flow cross-sectional area from the point of the closest air supply orifice (21) to a distance of a downstream length (L2) which is at minimum equal to the mean diameter of the flow cross-sectional area (A2a, A2b) of the throttle ducts. The throttle section has transverse gas ducts (2), which open into the throttle ducts (6a, 6b) on the first side of a plane running through the throttle duct center line (8) and which continue as a connecting duct (7) outside the throttle ducts to the opposite side of the said plane and further to the gas/gas mixture source (20).

  • Publication number: 20030075813
    Abstract: The invention relates to a carbonating device for charging a liquid with a pressurized gas. Carbonating devices of this type are generally used for adding carbon dioxide or CO2 to tap water or so-called still water. According to the invention, the pivotal filling device can be locked into a so-called pivotal position in a manner that makes the inventive carbonating device easier to handle than commercially available carbonating devices. The invention provides that the pivotal filling device can be firstly brought into the pivotal position and locked in place by using one hand. Afterwards, the water bottle can be clamped or screwed onto the filling device by using both hands. Together with the water bottle, the filling device is then released from its locked position and placed into the so-called filling position.

  • Patent number: 6454247
    Abstract: An anti-draft shutter assembly for an axial flow fan fitted to a duct. The assembly includes at least one counterbalanced flap supported downstream of airflow from the fan when in operation, and at least one of the flaps being pivotally supported outside the perimeter of the duct. The flap is biased by a counterbalance weight toward a duct closing position to close the duct when the fan is not operating. In the preferred embodiment, at least one flap is held in the closed position by a magnetic catch on the flap.
