A joint assembly (1; 1'; 1") for joining a ceramic membrane (2; 2'; 2") of tubular form to a tube sheet (3) used in supporting the ceramic membrane (2; 2'; 2") within a reactor. The ceramic membrane (2; 2'; 2") is received within a fixture (10; 32; 50) connected to the tube sheet (3) and a follower (12; 44; 54), extending into the fixture (10; 32; 50) exerts a force on a high , temperature sealing element (16; 42; 72) located between the fixture (10;32;50) and the ceramic membrane (2; 2'; 2") to effect a seal and to hold the ceramic membrane (2; 2'; 2") in place. The force can be exerted directly on the sealing element (16, 72) or on the ceramic membrane (2') itself.

Why it's free to use
- Filed March 19, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 19, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 19, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
