Abstract: Apparatus for use with a conventional caulking gun for enabling a user to clean caulk from the user's finger or fingers includes an open-topped receptacle defining an upper edge and a finger-receiving cut-out portion defined within the edge. Clips are connected to the receptacle for cooperating with the caulking gun and removably holding the apparatus in fixed position with respect to the gun so that the user can wipe his finger or fingers across the edge within the cut-out portion to remove caulk from the user's finger and to neatly collect the removed caulk within the receptacle.

Abstract: A flexible radial bi-directional seal for sealing a diaphragm against a sector plate in a rotating drum-type air preheater includes a baseplate assembly having a pair of rigid baseplates. Each baseplate has a planer section and a flange, with the baseplates joined together and the flanges generally curving away from each other and forming a longitudinal slot therebetween. A replaceable pack assembly includes a pack of parallel planer leaves separated by spacers. The replaceable pack is removably attached to the baseplate assembly with engagement edges of the leaves of the replaceable pack engaging the longitudinal slot.
