Abstract: An apparatus for inserting a venturi tube having an inlet, an aspirator inlet and an outlet directly within a fluid flow stream, with the aspirator inlet not in contact with the fluid flow stream is disclosed. A plate having a first aperture leading to the venturi inlet, and a series of second apertures both supports the venturi within a conduit and divides the fluid flow stream into a first stream which flows through the venturi tube and a second stream which flows around the venturi tube. A variety of adjusting mechanisms are disclosed for varying the cross sectional area of the second apertures relative to the cross sectional area of the venturi tube. The apparatus is adapted to allow the back pressure within the venturi tube (which increases as the fluid flow rate increases) to force an increasing proportion of the flow stream to flow around the venturi tube in order to maintain a relatively constant aspiration rate within the venturi tube.

Abstract: A computer system modeling tool generates a working user interface from the entities, attributes and relationships of a data model while assuring referential data integrity and and enforcing cardinality.

Abstract: A process and reactor for chemical conversion is taught. The process allows the selective breaking of chemical bonds in a molecule by use of fast rise alternating current or fast rise pulsed direct current, each fast rise portion being selected to have a suitable voltage and frequency to break a selected chemical bond in a molecule. The reactor for carrying out such a process includes a chamber for containing the molecule and a generator for generating and applying the selected fast rise current.

Abstract: A generator is taught which uses alternating current or pulsating direct current to produce ozone from oxygen. The generator comprises a high voltage and ground electrode separated to form a gap for accommodating a dielectric member and gas to be reacted. The generator includes many features which may be used alone or in combination to provide an energy efficient and safe apparatus.
