  • Patent number: 4114248
    Abstract: The resiliently coated metallic finger seal described herein is formed of two metallic seal members being fixed together at one end with fingers projecting rearwardly therefrom. The fingers on each member are offset so that the slits of each metallic seal member are not aligned. The fingers of the two members are then encapsulated by a resilient coating material, such as a room temperature vulcanizing silicone rubber. The seal means is described as annular and can be constructed of one piece or a plurality of sections. In constructing the seal means the metallic seal members are cleaned, primed where it is desired to have the resilient coat permanently affixed, and the resilient coat is then applied. The resilient coat does not cover the entire fingers so that the proper flexibility at the hinge location will reamin. After curing of the resilient coating material a heat reflecting and lubricating material is placed thereon.

  • Patent number: 3972475
    Abstract: An exhaust nozzle has main flaps with seals therebetween. Each flap and seal is constructed having inner and outer members which cooperate to form a liner for passing cooling air therethrough which extends substantially around the entire circumference of the liner. The inner member of each of the seals is riveted at its forward end to a guide and support member which is in turn fixed to its outer member while the remainder of the inner member is permitted thermal growth by sliding on said guide and support member. The outer member is bolted to the guide and support means. Said guide and support means being corrugated to permit cooling flow therethrough with the heighth of the corrugations providing the proper contour for the inner member.
