Pressure Equalizing Fluidborne Sound Projector
Pressure Equalizing Fluidborne Sound Projector
US Patent:
7136324, Nov 14, 2006
Filed:
Oct 28, 2004
Appl. No.:
10/975111
Inventors:
James M. Quigley - Philadelphia PA, US
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01V 1/137
US Classification:
367143, 367167
Abstract:
A solid metallic piston of a fluidborne sound projector is provided with a plurality of parallel spaced fluid passages extending between opposite axial end faces of the piston so as to equalize fluid pressures exerted thereon within a chamber enclosed within an end portion of a conduit having an end wall attached thereto through which a solid piston rod extends from the piston to an acoustical power source from which acoustical energy is mechanically transmitted as displacing forces applied to one of the axial end faces of the piston. Displacement of the piston within the chamber is limited in one axial direction by abutment of the rear end face thereof with the conduit end wall and in the other axial direction by abutment of a larger diameter section of the piston with a forward stop on an annular seal fixed to the conduit end portion, through which a smaller diameter section of the piston extends from the larger diameter section.

US Patent:
7278514, Oct 9, 2007
Filed:
Oct 17, 2003
Appl. No.:
10/693849
Inventors:
James M. Quigley - Philadelphia PA, US
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
F01N 1/22, F01N 1/24, F16L 55/027, F16L 55/04
US Classification:
181256, 181252, 181222, 181249, 181255, 181277, 181278, 181250, 181273, 181276, 181212, 181219, 181227, 181233, 181248
Abstract:
An acoustic filter is provided with a single flow chamber for exposure of a flexible rubber layer to liquid undergoing flow through the flow chamber with noise producing acoustic energy therein. The flexible rubber layer is supported on a cylindrical drum with slanted holes therein through which the exposure to the liquid in the flow chamber is effected. An axially sectioned drum with dimensionally different diameters, radial thicknesses and slanted holes therein is positioned over the rubber layer within an outer casing to establish a plurality of gas-filled cavities of different axial lengths and separated from each other along the axial length of the liquid flow chamber which is connected at its opposite axial ends by pipe sections to a piping system from which the liquid within the flow chamber is derived.
