  • Publication number: 20190257330
    Abstract: A vortex flow catalytic conversion apparatus and a method of vortex flow catalytic conversion of a fluid is provided. The apparatus includes a housing having an interior surface defining a cylindrical chamber. A helical separator is disposed within the chamber and cooperates with the interior side wall of the chamber to define a helical passageway for inducing a vortex flow. A deflector is disposed downstream of the helical separator to redirect the vortex flow exiting the helical passageway to an axial flow. A catalytic converter is disposed in the chamber downstream of the deflector. A catalyst coating is applied to at least one of the interior surface, helical separator, and catalytic converter. The method includes exposing a vortex flow of fluid to a first catalyst coating. The vortex flow is then redirected to an axial flow and exposed to a second catalyst coating.

  • Publication number: 20180066563
    Abstract: A vortex flow apparatus including a cylindrical housing that contains a fluid that flows in a swirling circular path. The apparatus may be utilized as a muffler for a combustion engine, a particle separator, or an energy conversion device that physically or chemically acts upon the fluid flow and particles contained within the apparatus. The housing defines an inlet opening that opens into the first end of the housing proximate a first end wall. An outlet tube defines an outlet opening through a first end wall. A projection is attached to a second end wall of the housing and extends into the housing. The outlet tube and projection are aligned with and centered relative to a central axis.

  • Patent number: 8468577
    Abstract: A system and method for developing websites for members of an organization include configuring and storing organization content using a server computer associated with the organization, configuring and storing member content associated with the members of the organization using the server computer, screening member content based by applying an organization policy stored on the server computer to prohibit specified information from being included in member content, and delivering a web page having the enterprise content arranged with member content in response to a request by a user for viewing a webpage having a URL corresponding to one of the members of the organization. The systems and methods may also include storing a visibility level for specified member content that limits access to the specified member content only to authorized users within the organization, in a specified group, by password, or private to the member, for example.

  • Patent number: 5482278
    Abstract: A golf course which is accessible to the physically handicapped. A clubhouse is equipped with wheelchair-accessible ramps, wheelchair-accessible toilets and necessary medical supplies and equipment. Rest houses are located on the course to provide rest, refreshment, and medical aid. The course is substantially flat to make it accessible to wheel chairs. It contains no water hazards. The surface of the greens is constructed of artificial turf. Playing hazards include boulders, concrete slabs, and sand traps. The sand traps are of such a size and arrangement so as to allow the maneuvering of wheelchairs. Blind golfers may play as the holes are equipped with buzzers which emit sounds which allow the determination of the location of the holes and additional buzzers which signal the entry of the ball into the hole.
