Abstract
Abstract A solar alignment device for positioning a solar grill so that its collector plate is perpendicular to the incoming rays of the sun. The device is comprised of a light-transmitting fiber cable with one end recessed below an aperture that faces the sun in front of the grill, and the other end affixed to the top of the grill, facing the viewer. The positioning of the individual fiber ends within the cable, in combination with the aperture, provides a simple, economical and precise means for adjusting the solar grill to obtain the maximum solar incidence on its collector plate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
133 words
On a solar grill, including an outer frame defining an opening in which an essentially flat collector plate is disposed within the frame, a display device for indicating the position of the sun, relative to a position which is perpendicular to the collector plate of such grill, comprising: an enclosure with an aperture at one end and an opening at the other end operably connected to pass light therebetween, said enclosure connected to said outer frame with the said aperture parallel to the plane of said collector plate; a flexible, light-transmitting cable having one end connected to said opening, below said aperture, said enclosure having light-absorbing interior walls and said enclosure connected to said grill frame, and said cable having a display end connected to said frame at a location suitable for viewing.
Claim 2
Dependent Claim
133 words
On a solar grill, including an outer frame defining an opening in which an essentially flat collector plate is disposed within the frame, a display device for indicating the position of the sun, relative to a position which is perpendicular to the collector plate of such grill, comprising: an enclosure with an aperture at one end and an opening at the other end operably connected to pass light therebetween, said enclosure connected to said outer frame with the said aperture parallel to the plane of said collector plate; a flexible, light-transmitting cable having one end connected to said opening, below said aperture, said enclosure having light-absorbing interior walls and said enclosure connected to said grill frame, and said cable having a display end connected to said frame at a location suitable for viewing.
Claim 3
Dependent Claim
19 words
A display device as set forth in claim 1, wherein: said light-transmitting cable is a transparent glass fiber material.
Claim 4
Dependent Claim
19 words
A display device as set forth in claim 1, wherein: said light-transmitting cable is a transparent plastic fiber material.
Claim 5
Dependent Claim
45 words
A display device as set forth in claim 1, wherein: said light-transmitting cable includes a central, light-transmitting fiber and a plurality of additional light-transmitting fibers surrounding and separated from said central fiber, said additional fibers forming at least one circular ring around said central fiber.
Claim 6
Dependent Claim
30 words
A display device as set forth in claim 4, wherein: the display end of said central fiber is of a different color than the display ends of said additional fibers.
Claim 7
Dependent Claim
53 words
A display device as set forth in claim 4, wherein: one end of said light-transmitting cable is rotated 180 degrees, and fixed to said frame in rotated position, to reverse the relative position of the ends of said additional fibers with respect to said central fiber on an axis through said central fiber.
Claim 8
Dependent Claim
44 words
A display device as set forth in claim 4, wherein: the distance between any two adjacent fiber ends within said cable end connected to said opening is less than the distance between any two adjacent fiber ends at the display end of said cable.
Claim 9
Dependent Claim
35 words
A display device as set forth in claim 1, wherein: the distance between said aperture and said cable end connected to said opening below said aperture is greater than the minimum width of said aperture.
Claim 10
Dependent Claim
28 words
A display device as set forth in claim 1, wherein: the least interior dimension of said enclosure is greater than the width of said aperture in said enclosure.
Claim 11
Dependent Claim
106 words
A display device for indicating the position of the sun, relative to a position which is perpendicular to a surface on a frame, comprising: an enclosure with an aperture at one end and an opening at the other end operably connected to pass light therebetween, said enclosure connected to said frame with the said aperture parallel to the plane of said surface, a flexible, light-transmitting cable having one end connected to said opening, below said aperture, said enclosure having light-absorbing interior walls and said enclosure connected to said frame, and said cable having a display end connected to said frame at a location suitable for viewing.
Claim 12
Dependent Claim
