Patent number: 8146893Abstract: Apparatus and methods for generating and tracing vortices include an actuator that is moved through a fluid is such a fashion as to produce a difference in pressure between two faces, so that the fluid is drawn from an area of higher pressure into an area of lower pressure around an edge of the actuator, thereby producing a vortex. A vortex generator produces vortices in air or other fluid, without an external chamber being required. The rotational velocity of such a vortex is greater than the rotational velocity of the actuator. The shape, size, and strength of the vortices can be controlled by varying one or more of the size, shape, and speed of the apparatus' actuator including its leading and trailing edges, height of the actuator above the surface, and the angles between the plane of the actuator and the motion through the fluid. A vortex may be visualized easily using a tracing material which is introduced into the vortex.Type: GrantFiled: November 19, 2008Date of Patent: April 3, 2012Inventor: Timothy Allen Zapalski

Patent number: 8128741Abstract: A dissolving apparatus has a cylindrical tubular container closed at both ends with its center axis being inclined to the horizon. A center of an interface between a gas and a liquid in the container is positioned at a center in a lengthwise direction of a side wall of the container. Two inner spaces of the container above and below the interface are referred to as a gas section and a liquid section. An injection inlet for injecting a gas-liquid mixed fluid into the container is provided at a level corresponding to, or lower than, the interface. A liquid outlet for discharging the liquid is provided near a bottom of the liquid section of the container. Since the container is inclined, the interface can have an area large enough to promote dissolution of the gas into the liquid. Since the depth of the liquid in the liquid section is sufficiently deep, the liquid can be prevented from being discharged through the liquid outlet with large gas bubbles being present therein.Type: GrantFiled: May 28, 2007Date of Patent: March 6, 2012Assignee: Panasonic Electric Works Co., Ltd.Inventors: Yasunari Maeda, Shigeyuki Yamaguchi, Kazumasa Rokushima, Naoki Shibata, Hitoshi Kitamura, Noriyuki Kitachi, Yoshihiro Itou, Takaya Niu

Publication number: 20110127682Abstract: The device is of the frustum dispersion type having a housing forming a conical cavity, sealed at its large end, tapering to a discharge orifice at the other end. There is a fluid inlet, which tangential to the cavity near the sealed end. There is a hollow, tapered helix cut cone shape in the center of the cavity, affixed to the sealed end, with the point thereof axially aligned with the discharge orifice to help enable the continuous swirling motion of the contained fluid and to act as a gas inlet port to start the formation of a gas vortex. As fluid in the cavity approaches the discharge orifice, it is accelerated because of the reduction of area inside the cavity as it tapers. The change in specific gravities between the fluid and the gas causes a swirling centrifugal force on the liquid and a centripetal inner swirling of the gas. The result is at the point of discharge, the fluid is heavily loaded with small bubbles of gas.Type: ApplicationFiled: February 23, 2009Publication date: June 2, 2011Applicant: BLUE PLANET ENVIRONMENTAL INC.Inventors: David Burns, Jason Yeo, Richard Lonetto

Patent number: 7628924Abstract: The invention relates to an apparatus and method for more effectively dissolving a gas into a liquid stream. A gas is introduced into a liquid stream, at atmospheric pressure, to create a mixed/dissolved stream.

The intimately mixed/dissolved stream is then directed to a pressure retention vessel where the liquid is held at a predetermined pressure for a predetermined time period for effectively treating, disinfecting and/or clarifying said intimately mixed/dissolved stream. The treated intimately mixed/dissolved stream can then be directed to further processing steps.Type: GrantFiled: October 21, 2005Date of Patent: December 8, 2009Inventors: Nels Robert Ladouceur, Peter Douglas Jack

Publication number: 20070278702Abstract: A humidifier which creates a visually entertaining helical flow of mist generally includes a base unit defining a reservoir for holding a quantity of water, a water tank supported on the base unit for supplying water to the reservoir, a humidification device, such as an ultrasonic transducer, in communication with the reservoir for vaporizing the water held in the reservoir to produce a mist, a vortex unit supported on the base unit and a nozzle and a vortex creator positioned in the vortex unit. The vortex unit has an opening disposed above the base unit reservoir to permit the mist produced by the humidification device to rise upwardly into the vortex unit.Type: ApplicationFiled: June 1, 2006Publication date: December 6, 2007Inventors: Jon French, Johnson Hsu

Patent number: 7300040Abstract: An apparatus and method are described that allows for the production of vortex-ring bubbles in a liquid. The device is an inverted cup with a short nozzle protruding through the center of its end face such that the nozzle lower opening is at a higher level than the open end of the inverted cup. When the immersed cup is pressurized with an inflow of gas, the liquid level of the confined gas in the cup will fall, and peel away from the nozzle open end. The gas will enter the nozzle when the pressure has built up within the cup sufficiently to break the liquid surface tension at the nozzle opening. The gas then self accelerates up through the nozzle and self organizes into a gas-filled vortex ring at the nozzle exit. The liquid level in the cup rises back up and re-enters the nozzle in a unique self-siphoning action shutting off further gas flow out the nozzle.Type: GrantFiled: December 23, 2004Date of Patent: November 27, 2007Inventor: Andrew Sydney Withiel Thomas

Patent number: 7261283Abstract: The swirling type micro-bubble generating system according to the present invention possesses a container main unit having a cylindrical space with bottom or a frusto-conically shaped space, a liquid inlet provided in a tangential direction on a part of a circumferential surface of an inner wall of said space, a gas introducing hole provided on the bottom of said cylindrical space or opening of said frusto-conically shaped space, and a swirling gas-liquid mixture outlet arranged at the opposite end of said cylindrical space or opening of said frusto-conically shaped space. According to this system, it is possible to readily generate micro-bubbles in an industrial scale, and the system is relatively small in size and has simple structure and can be easily manufactured. The system can be used in applications such as purification of water quality in ponds, lakes, marshes, man-made lakes, rivers, etc.Type: GrantFiled: May 15, 2000Date of Patent: August 28, 2007Inventor: Hirofumi Ohnari

Patent number: 7240897Abstract: Mixing apparatus is disclosed suitable for the mixing and/or aeration of large bodies of water e.g. lakes or reservoirs. One particular use is in causing controlled destratification. Another area of use is in the aeration or oxygenation of liquid waste. The mixing apparatus has a draft tube (1) with an open interior, and gas injectors (6) to drive an upward flow of liquid through the draft tube (1). An arrangement of angled vanes (4) at the intake of the draft tube imposes swirl on the flow, which then rises unobstructed through the draft tube (1). No moving parts are involved.Type: GrantFiled: January 28, 2003Date of Patent: July 10, 2007Inventor: Anthony G. Wynes
