Abstract: An archery bow includes a main riser frame with limbs extending therefrom. Each of the limbs has forward ends extended from the main riser frame. A bowstring has wound ends that are wound onto each of wheel cams that are attached to the limbs. The bowstring has a middle section that is not wound onto the wheel cams and that begins and ends at points on the wheel cams that are proximate to the farthest points along the wheel cams from the main riser frame. An elongate tube is mounted to the main riser frame through the central bore, and has a front handle attached to the elongate tube outer surface, and positioned between the first and second pairs of limbs. A push rod is slidably mounted at least partially inside the elongate tube, and has a rearward handle disposed outside the elongate tube rearward end.

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.
