Filed:

Jun 15, 2011

Appl. No.:

13/161423

Inventors:

Ben L. DeJesus - Carson CA, US

International Classification:

F01D 5/14

US Classification:

416241 R

Abstract:

A device having a pair of blades spinnable about a spin axis. The pair of blades includes a first blade and a second blade, with the first blade canted about a first-blade canting axis at a first-blade canting angle and the second blade canted about a second-blade canting axis at a second-blade canting angle. The first-blade canting axis is oriented at a first-blade canting axis angle relative to a first-blade radial and the second-blade canting axis is oriented at a second-blade canting axis angle relative to a second-blade radial, each canting axis angle being other than 90 degrees. The first-blade radial is oriented perpendicular to a first chord plane that passes through the first blade and contains a first-blade chord, and the second-blade radial is oriented perpendicular to a second chord plane that passes through the second blade and contains a second-blade chord. The first-blade chord is oriented at a first-blade chord pitch angle determined at least in part by the first-blade canting axis angle and the first-blade canting angle. The second-blade chord is oriented at a second-blade chord pitch angle determined at least in part by the second-blade canting axis angle and the second-blade canting angle.

Appl. No.:

7/560063

Inventors:

Ben L. DeJesus - Carson CA

International Classification:

G02B 308

US Classification:

359742

Abstract:

An optical system is provided for magnifying the image on a television receiver to viewers in a room. The system is comprised of a plano-convex lens disposed in front of the viewing screen of a television set and a fresnel lens interposed between the viewing screen and the plano-convex lens. The fresnel lens has a smooth surface and an opposite surface configured with a pattern of concentric dioptric ridges facing the plano-convex lens. The magnification achieved by the combination of lenses allows viewers within the room to view a magnified image on the television receiver. Preferably, the planar surface of the plano-convex lens and the smooth surface of said fresnel lens are both disposed to face the television screen so that the television screen can be viewed without significant aberrations or distortion from a wide range of viewing distances.

Appl. No.:

16/171964

Inventors:

Ben L DeJesus - Carson CA, US

International Classification:

A63B 53/04

Abstract:

The head of a golf iron having an improved profile that enables a golfer to accurately align the club head with a golf ball so that the club head will strike the ball at the sweet spot located on the club face. The club head has a top edge which runs above the club face and includes first and second portions that extend in first and second directions. The boundary line between the first and second portions at the top edge of the club head lies in a vertical sweet spot reference plane with the center of the sweet spot. The boundary line at the top edge of the club head is visible to the golfer looking down at his club head so as to provide the golfer with an indication of the location of the sweet spot on the club face at which to strike the golf ball during his swing.
