Abstract: A mounting assembly for securing an electrically conductive rail to a support structure comprises a resilient clip configured to grasp an electrically insulating sleeve that encloses the electrically conductive rail. A longitudinal opening in the sleeve exposes the rail so as to permit sliding electrical contact along the rail by a shoe or other type of conductor for providing power to an electrically driven movable device or vehicle that travels along a track or pathway defined generally by the rail. The resilient clip is seated within a bracket, and a securing means coadunately fastens the clip to the bracket and the bracket to the support structure. A plurality of such mounting assemblies can be used to secure a plurality of such rails to the support structure in adjacent parallel disposition with respect to each other, where each mounting assembly secures a corresponding one of the rails to the support structure independently of the other mounting assemblies.

Indexing of the turret will select either the drilling carriage, the cartridge inserter or the bolt insertion carriage into an operating position, as desired.

Abstract: A system for drying and burning wet waste materials includes a multiple hearth furnace having an upper, drying zone and a lower, burning zone. Wet waste material is introduced into the upper, drying zone and dried with a stream of hot air, and the stream of air is then conveyed to a condenser to remove water. The stream of air from the condenser is then conveyed to the center column of the furnace wherein it is heated, and the hot air is then introduced into the lower, burning zone of the furnace to aid combustion. Hot gaseous products of combustion are conveyed from the burning zone to an afterburner, and the gases leaving the afterburner are transferred to a heat exchanger and then discharged. In the heat exchanger a stream of ambient air is heated, and the heated air is then conveyed to the upper, drying zone.
