Claim 2

The combintion of two juxtaposed, non-ductile, non-metallic components and a continuous body of material disposed between and separating said components and bonded thereto for limiting stresses on said components, said material being a low strength, glass or metallic adhesive that will flow under changing supra-ambient temperature conditions while remaining a continuous body and bonded to said components when subjected to stresses lower than those capable of causing fractures in said components.

Claim 3

A combination as defined in clain 1 in which the material disposed between the non-ductile components is time-load sensitive.

A combination as defined in claim 1 in which the material disposed between the non-ductile components is a load-sensitive compliant interlayer.

Claim 6

A combination as defined in claim 1 in which the material disposed between and in bonded relationship with said non-ductile components to provide a seal therebetween consists essentially of one of the group consisting of copper/silver alloys, stainless steels, austenitic steels, silicide coated columbium, and high glass silicon nitrides.

Claim 7

A combination as defined in claim 1 in which the material is a glass adhesive and in which said glass adhesive is essentially free of devitrification promoting additives and comprises at least one strong glass former.

Claim 8

The combination of a device having two non-ductile, non-metallic components; means for changing the temperature of said components from a first to a second temperature; and means for attenuating stresses in said components as their temperature changes and differential expansion or contraction of the component occurs, said last-mentioned means comprising a glass or metallic adhesive of sufficient plasticity to permit said components to move relative to each to attenuate the stresses generated by said differential expansion or contraction, said adhesive being disposed in a continuous body between and interfacing in bonded relationship with said components to provide a seal therebetween.

Claim 9

The combination of a device having two non-ductile, non-metallic components; means for changing the temperature of said components from a first to a second temperature; and means for attenuating stresses in said components as their temperature changes and differential expansion or contraction of the component occurs, said last-mentioned means comprising a glass or metallic adhesive of sufficient plasticity to permit said components to move relative to each to attenuate the stresses generated by said differential expansion or contraction, said adhesive being disposed in a continuous body between and interfacing in bonded relationship with said components to provide a seal therebetween.

Claim 10

A combination as defined in claim 6 in which the material disposed between the non-ductile components is time-load sensitive.

Claim 11

A combination as defined in claim 6 in which the material disposed between the non-ductile components is a load-sensitive compliant interlayer.

Claim 12

A combination as defined in claim 6 in which the material disposed between the non-ductile components consists essentially of one of the group consisting of copper/silver alloys, stainless steels, austenitic steels, silicide coated columbium, and high glass silicon nitrides.

Claim 13

A combination as defined in claim 6 in which the material disposed between the non-ductile components is a glass adhesive and in which said glass adhesive is essentially free of devitrification promoting additives and comprises at least one strong glass former.

Claim 16

A method as defined in claim 11 in which the material disposed between the non-ductile components is time-load sensitive.

Claim 17

A method as defined in claim 11 in which the material disposed between the non-ductile components is a load-sensitive compliant interlayer.

Claim 18

A method as defined in claim 11 in which the material disposed between the non-ductile components consists essentially of one of the group consisting of copper/silver alloys, stainless steel, austenitic steels, silicide coated columbium, and high glass silicon nitrides.

Claim 19

A method as defined in claim 11 in which the material disposed between the non-ductile components is a glass adhesive and in which said glass adhesive is essentially free of devitrification promoting additives and comprises at least one strong glass former.

Claim 20

The combination of two non-ductile components; a material disposed in a space between and interfacing with said components to provide a seal therebetween, said material being plastic and remaining a continuous body providing a seal between said components under conditions involving changing supra-ambient temperature conditions and a differential expansion of the non-ductile components, whereby said components can move relative to each other to inhibit the build-up of stresses in said components without disrupting the seal therebetween; and reservoir means in at least one of the non-ductile components from which material expelled from the joint can be replenished; said reservoir being filled with said material and being in communication with the space between said components.

Claim 21

The combination of two non-ductile components; a material disposed in a space between and interfacing with said components to provide a seal therebetween, said material being plastic and remaining a continuous body providing a seal between said components under conditions involving changing supra-ambient temperature conditions and a differential expansion of the non-ductile components, whereby said components can move relative to each other to inhibit the build-up of stresses in said components without disrupting the seal therebetween; and reservoir means in at least one of the non-ductile components from which material expelled from the joint can be replenished; said reservoir being filled with said material and being in communication with the space between said components.
