Abstract
Abstract A curved glass X-Ray reflector having a curve depth d' including a glass plate having a stiffness S 1 ; a backing plate having a stiffness S 2 and a curved surface with curve depth d; and bonding means for joining the glass plate to the curved surface, the resulting curved glass reflector having curve depth d', where d' is equal to d/R and R is the ratio of (S 1+ S 2 )/S 2 ; and a method of making such a reflector.

Claim 1
Independent Claim
87 words
A method of forming a curved, glass reflector having a curve depth d' comprising: forming, in a metal leaf spring backing plate having a stiffness S 2 , a curved surface having a curve depth d; bonding to said curved surface a flat glass plate having a stiffness S 1 ; and after bonding, permitting said bonded plates to adjust to an equilibrium curved formation in which the curve depth is d' where d'=d/R and R is the ratio of (S 1 +S 2 )/S 2 .
Claim 2
Independent Claim
87 words
A method of forming a curved, glass reflector having a curve depth d' comprising: forming, in a metal leaf spring backing plate having a stiffness S 2 , a curved surface having a curve depth d; bonding to said curved surface a flat glass plate having a stiffness S 1 ; and after bonding, permitting said bonded plates to adjust to an equilibrium curved formation in which the curve depth is d' where d'=d/R and R is the ratio of (S 1 +S 2 )/S 2 .
Claim 3
Independent Claim
85 words
A method of forming a curved, glass reflector having a curve depth d' comprising: forming, in a glass backing plate having a stiffness S 2 , a curved surface having a curve depth d; bonding to said curved surface a flat glass plate having a stiffness S 1 ; and after bonding, permitting said bonded plates to adjust to an equilibrium curved formation in which the curve depth is d' where d'=d/R and R is the ratio of (S 1 +S 2 )/S 2 .
Claim 4
Independent Claim
85 words
A method of forming a curved, glass reflector having a curve depth d' comprising: forming, in a glass backing plate having a stiffness S 2 , a curved surface having a curve depth d; bonding to said curved surface a flat glass plate having a stiffness S 1 ; and after bonding, permitting said bonded plates to adjust to an equilibrium curved formation in which the curve depth is d' where d'=d/R and R is the ratio of (S 1 +S 2 )/S 2 .
Claim 5
Dependent Claim
78 words
A curved glass reflector having a curve depth d' comprising: a flat glass plate having a stiffness S 1 ; a backing plate including a glass plate having a stiffness S 2 and a curved surface with an initial curve depth d; and bonding means for joining said glass plate to said curved surface, the joined plates having curve depth d', where d' equals d/R and R is the ratio of (S 1 +S 2 )/S 2 .
