Abstract
Abstract This reflecting device is for use wherein the reflecting surface is subjected to heat and includes a thick backing member with channels on one surface thereof with one surface of a cover member fixed to said channeled surface forming passages. A reflecting surface is formed on the other surface of the cover member and a manifold system directs a coolant through the passages formed by the channels of the backing member and the mating surface of the cover member. The manifold system includes an inlet and an outlet which can be connected to any desired control means to achieve the proper flow. This cooling arrangement not only provides the cooling necessary to maintain the reflecting device in an operating condition but also maintains the high quality of the reflecting surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
102 words
An optical reflecting device for operating under heat comprising a thick backing member having a metallic surface of a predetermined shape, a second relatively thin metallic platelike member fixed to the surface thereof, one of said members having channels on the side facing the other member, said channels forming webs therebetween, the free faces of the webs being fixed to the other member, said channels forming passages with the other member, a coolant manifold system comprising at least two manifolds, said manifold system being connected to said passages, said free face of said second member being treated to form a reflecting surface.
Claim 2
Dependent Claim
102 words
An optical reflecting device for operating under heat comprising a thick backing member having a metallic surface of a predetermined shape, a second relatively thin metallic platelike member fixed to the surface thereof, one of said members having channels on the side facing the other member, said channels forming webs therebetween, the free faces of the webs being fixed to the other member, said channels forming passages with the other member, a coolant manifold system comprising at least two manifolds, said manifold system being connected to said passages, said free face of said second member being treated to form a reflecting surface.
Claim 3
Dependent Claim
18 words
A reflecting device as set forth in claim 1 wherein the manifold system is formed within the device.
Claim 4
Dependent Claim
28 words
A reflecting device as set forth in claim 2 wherein said thick backing member has a manifold formed iN each side thereof with said channels being connected therebetween.
Claim 5
Dependent Claim
17 words
A reflecting device as set forth in claim 1 wherein the contour of the channels is rectangular.
Claim 6
Dependent Claim
23 words
A reflecting device as set forth in claim 1 wherein means directs a coolant into said manifold system for flow through said passages.
Claim 7
Dependent Claim
29 words
A reflecting device as set forth in claim 1 wherein the ratio between the thickness of said backing member and the thickness of the second member thickness is large.
Claim 8
Dependent Claim
24 words
A reflecting device as set forth in claim 1 wherein the free face of the second member has a layer of reflective material thereon.
Claim 9
Dependent Claim
22 words
A reflecting device as set forth in claim 1 wherein the channels are formed on the surface of said thick backing member.
Claim 10
Dependent Claim
32 words
A reflecting device as set forth in claim 3 wherein the channels are formed on the surface of said thick backing member, each end of said channels intersecting one of said manifolds.
Claim 11
Dependent Claim
22 words
A reflecting device as set forth in claim 1 wherein the free faces of the webs are brazed to the other member.
