Abstract: A pliable refractory metal carrier (46) may have coated thereon an anchor layer (47) to improve adherence to the carrier (46) of a catalytic coating (48). The conformable catalyst member (26, 82, 82?, 126, 226, 326) may be bent to conform to a curved or bent exhaust pipe (20, 220, 320) within which it is mounted. The pliable metal carrier may be in the form of a tube such as carrier (46) having perforations (54) formed therein, or it may be a metal strip (76) which is folded into accordion pleats (80) and has perforations (78) formed therein. The perforations (54, 78) serve to permit the passage of exhaust gas therethrough. A series of interior closures (58) and annular baffles (60) may be provided to import a serpentine flow path to gases flowed through an exhaust pipe (22) containing a conformable catalyst member (226) therein. A mounting member (68) may be supplied to fasten one end of the conformable catalyst member (226) to the discharge end of an exhaust pipe (220).

Abstract: A tool for removing a cap from a pest control device includes a hub and at least four fingers depending from the hub in circumferentially spaced relationship with each other to cooperatively define a socket for receiving the cap within the tool. The fingers are resiliently moveable transversely outward relative to the hub upon receiving the cap into the socket whereby the fingers are biased transversely inward against a sidewall of the cap when the cap is received in the socket. A plurality of stops extends from fewer than all of the fingers laterally inward of the socket. The stops are adapted for contacting a top of the cap upon receipt of the cap within the socket such that the fingers and stops cooperate to orient the tool on the cap.
