Abstract
Abstract Solar sensor with linear concentration with a fixed receiver and movable mirrors. The solar sensor with a linear concentration comprises a system of elementary segmental mirrors arranged along the generating lines of a cylinder portion and directs the solar rays towards a zone located in the vicinity of a generating line of said cylinder and a receiver having a linear configuration arranged in said zone, wherein the receiver is stationary and means are provided for giving the mirror system a rotational movement without sliding so that the zone at which the reflected rays are directed remains fixed and the direction of the reflected rays remains unchanged when the sun's position changes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A solar sensor with linear concentration comprising: a system of elementary segmental mirrors arranged along the generating lines of a cylinder portion and directing the solar rays to a zone located in the vicinity of a generating line of said cylinder portion, and a receiver of linear configuration located in said zone, said receiver being stationary, and means for ensuring that the mirror system is subject to a rotational movement without sliding movement in such a way that the zone towards which the reflected rays are directed remains fixed and the direction of said reflected rays remains unchanged when the position of the sun changes, said means comprising the first cylinder portion which supports the mirrors and a second fixed cylinder portion whose radius is equal to the diameter of the first cylinder portion and whose axis coincides with the receiver.
Claim 2
Dependent Claim
141 words
A solar sensor with linear concentration comprising: a system of elementary segmental mirrors arranged along the generating lines of a cylinder portion and directing the solar rays to a zone located in the vicinity of a generating line of said cylinder portion, and a receiver of linear configuration located in said zone, said receiver being stationary, and means for ensuring that the mirror system is subject to a rotational movement without sliding movement in such a way that the zone towards which the reflected rays are directed remains fixed and the direction of said reflected rays remains unchanged when the position of the sun changes, said means comprising the first cylinder portion which supports the mirrors and a second fixed cylinder portion whose radius is equal to the diameter of the first cylinder portion and whose axis coincides with the receiver.
Claim 3
Dependent Claim
28 words
A solar sensor according to claim 1, wherein the mirrors are cylindrical and have a radius equal to double the diameter of the cylinder portion supporting the same.
Claim 4
Dependent Claim
37 words
A solar sensor according to claim 1, wherein the said means are able to move a point of a generating line of the mirror supporting cylinder along a diameter of the fixed cylinder having a double radius.
Claim 5
Dependent Claim
16 words
A solar sensor according to claim 3, wherein said means comprise a rack and pinion assembly.
Claim 6
Dependent Claim
164 words
A solar sensor with linear concentration comprising: a system of elementary segmental mirrors arranged along the generating lines of a first cylinder portion and directing the solar rays to a zone located in the vicinity of a generating line of said cylinder portion and a receiver of linear configuration located in said zone, said receiver being stationary, and means for ensuring that the mirror system is subject to a rotational movement without sliding movement in such a way that the zone towards which the reflected rays are directed remains fixed and the direction of said reflected rays remains unchanged when the position of the sun changes, said means comprising the first cylinder portion supporting the mirrors, and a second cylinder portion integral with said first cylinder portion and whose radius is double that of the first cylinder portion and which is tangential to the first cylinder portion,, and also comprising means which permit the rotation of said second portion on a plane without sliding.
Claim 7
Dependent Claim
164 words
