US Patent:

40778894, Mar 7, 1978

Filed:

Mar 17, 1976

Appl. No.:

5/667880

Inventors:

John Stewart Rhoades - Exton PA
Gary Kulp - Malvern PA

International Classification:

B01K 100

US Classification:

250543

Abstract:

A flexible technique for modifying various chemical substances utilizes a confined path to be followed by these substances in gaseous form or in a gaseous medium. Along this path there is positioned electrically energizeable means for establishing an electric field. Also along the path there are positioned electrically energizeable means for heating the gas to crack certain constituents into free elements; for combusting certain constituents; and for attracting certain constituents through affinity. The electrical energization of these means is controllable to provide the appropriate effect on the substances in the path.

Filed:

Sep 2, 1977

Appl. No.:

5/830329

Inventors:

John S. Rhoades - Exton PA
Patricia G. Rhoades - Marblehead MA

International Classification:

B63H 904

US Classification:

114103

Abstract:

An aerodynamic device mounted to a mainsail at the area of maximum air activity includes a venturi and a plurality of vertically disposed strips or offsets defining extending fins. The flow axis of the venturi is substantially parallel to the foot of the mainsail and the vertical fins are disposed in a substantially horizontal row along the venturi flow axis. Certain ones of the fins are positioned respectively forward and after the venturi and other ones of the fins are superimposed on the venturi. The aerodynamic device is operative to reach the free air layer beyond the zero activity and turbulent air layers for greater air drive and improved on-wind direction.

International Classification:

B01K 100

US Classification:

250543

Abstract:

Undesired emissions from such sources as automobile engines are controlled by providing a confined path to be followed by these, mostly gaseous substances to be controlled. Along this path there is positioned means for establishing an electric field. Preferably, in other portions of the path, there are positioned one or more of the following: means for heating the gas to crack certain constituents into free elements; means for combusting certain constituents; and means for attracting certain constituents through affinity.
