US Patent:

Filed:

Sep 28, 2000

Appl. No.:

09/672923

Inventors:

Michael Ferraro - Chicago IL 60645

International Classification:

F03D 900

US Classification:

290 55, 415 45, 244 53 R, 244 53 B, 261DIG 87

Abstract:

A wind powered generating device comprises a tube cluster, a collector assembly, and a turbine assembly. The collector assemblies utilize sails that can be rotated in the direction of the wind to direct wind down through an inlet tube to a central outlet tube. The central outlet tube is narrowed at a portion, and a turbine is mounted at this narrowed portion to take advantage of the venturi effect, which accelerates the air as it passes the turbine. This permits reliable and efficient operation in areas that were not formerly windy enough to be economically feasible. Alternative embodiments of the invention include mechanisms for dealing with violent weather conditions, a first of which allows excess wind to bleed off behind and between the sails, and a second which collapses and covers the sails with a protective sheath/sock.

Abstract:

A wind powered generating device comprises a tube cluster, a collector assembly, and a turbine assembly. The collector assemblies utilize sails that can be rotated to direct wind down through an inlet tube to a central outlet tube. The central outlet tube is narrowed at a portion, and a turbine is mounted at this narrowed portion to take advantage of the Venturi effect that accelerates the air as it passes the turbine. This permits reliable and efficient operation in areas that were not formerly considered windy enough to be economically feasible for the deployment of wind powered generating devices. Alternative embodiments of the invention include mechanisms for dealing with violent weather conditions, a first of which allows excess wind to bleed off beneath and between the sails, and a second which collapses and covers the sail with a protective sheath/sock.

US Patent:

Filed:

Jul 24, 1978

Appl. No.:

5/927282

Inventors:

Cosimo Del Prete - Chicago IL
Michael V. Ferraro - Chicago IL

International Classification:

B25B 1328

US Classification:

81111

Abstract:

An open end one way torque wrench has a wrench head recess in which a pair of articulated jaw members is adapted to receive and apply torque to a multifaced element by turning the wrench in one direction, and the jaw members automatically release and move into engagement with the next succeeding faces of the element by swinging the wrench in the opposite direction. The wrench head has a substantially semicircular track on which one of the jaw members rides. The other jaw member rides a tangential extension of the track. The jaw assembly is normally biased toward a torquing shoulder from which the assembly retreats during the release and re-engagement action of the jaw assembly.

International Classification:

H04R 102

US Classification:

179156R

Abstract:

A detachable earmuff has an entrance separation which is normally biased closed and which is resiliently flexibly openable for receiving a headband of a headset for retaining the earmuff in covering relation to a users ear and an earphone held to the users ear by means of the headband. For biasing the entrance separation, overlapping parts of a frame structure extend inwardly from the outer end of the entrance separation. In one embodiment the earmuff frame may comprise a generally flat split plastic ring. In another embodiment the earmuff frame may comprise a resilient wireform which may be constructed in one piece.
