Abstract
Abstract A solar heat collector including a panel having a coating of PbO 2 electrodeposited from a tartrate bath and a second coating of oxygen-deficient PbO 2 , such as α-PbO 2 or β-PbO 2 , heat being absorbable thereby and transferable to a liquid or gas for operating heating or cooling system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
68 words
A solar energy collector system comprising a heat transfer member, a first electrodeposited coating from a tartrate-containing bath of semiconductor PbO 2 on said member, a second electrodeposited coating of semiconductor oxygen-deficient PbO 2 having a high α and low ε on said first coating, means feeding fluid into heat transfer relation to said member, and means for feeding fluid from said member to a zone of utilization.
Claim 2
Dependent Claim
68 words
A solar energy collector system comprising a heat transfer member, a first electrodeposited coating from a tartrate-containing bath of semiconductor PbO 2 on said member, a second electrodeposited coating of semiconductor oxygen-deficient PbO 2 having a high α and low ε on said first coating, means feeding fluid into heat transfer relation to said member, and means for feeding fluid from said member to a zone of utilization.
Claim 3
Dependent Claim
17 words
A solar energy collector system as claimed in claim 1 wherein the tartrate is sodium potassium tartrate.
Claim 4
Dependent Claim
18 words
A solar energy collector system as claimed in claim 1 wherein the first coating is substantially void free.
Claim 5
Dependent Claim
19 words
A solar energy collector system as claimed in claim 1 wherein the second coating is from a non-tartrate bath.
