Abstract: The present invention discloses a support for securely holding an exhaust catalyst in a combustion and exhaust system. The support of the invention includes a flexible refractory mat adapted to surround the exhaust catalyst and a metal foil having a plurality of protrusions disposed over the flexible refractory mat. The present invention also discloses an exhaust system in which a catalyst is held in place with the support of the invention. Finally, methods for securing a catalyst to an exhaust system are provided.

Abstract: A sensor (24) having a metal shell (30) joined to a sleeve (96) to locate a heater (92) in a thimble of an electrolyte member (72). A sealed joint is produced between the sleeve (96) and metal shell (30) to define a sealed reference chamber (118). A porous filter (112) in the sleeve (96) prevents water in environmental air from entering the reference chamber (118). Leads (106') and 106") which pass through the porous filter (112) are connected to terminal (164 and 164'). Terminals (164 and 164') located in a terminal member (120) position a heater (92) within chamber (118) and the electrolyte member (72). Leads (106 and 106.sup.n) which pass through the porous filter are connected to contact rings (142 and 144). Contact rings (142 and 144) are connected to an external and internal coating (80 and 82) on the electrolyte member (72).
