Abstract: An air handling unit (AHU) comprises a shell defining a cavity and comprising at least an air ingress on a shell surface and an air egress on another shell surface, a condensing coil disposed with the cavity, a cooling coil disposed between the air ingress and the condensing coil, and an energy recovery coil disposed between the condensing coil and the air egress.

Abstract: An air handling unit (AHU), comprising: a shell defining a cavity and comprising at least an air ingress on a shell surface and an air egress on another shell surface; a condensing coil disposed within the cavity; a cooling coil disposed between the air ingress and the condensing coil; and an energy recovery coil disposed between the condensing coil and the air egress.

Abstract: A hopper car of a dump train for transporting material includes a hopper and a conveyor for loading the hopper with material. The loading conveyor includes a frame, a first pulley, a second pulley, and a continuous belt. The frame is attached to the car above the hopper. The first pulley is attached at one end of the frame adjacent an end of the hopper car. The first pulley has a motor positioned therein such that when the motor is operated the first pulley is rotated. The second pulley is attached at another end of the frame adjacent another end of the hopper car. The continuous belt is positioned on the first and second pulleys such that rotation of the first motorized pulley moves the continuous belt around the frame. A plow assembly is positioned on the frame and is operable to screed material off the continuous belt and into the hopper. The plow assembly includes a rotatable rod attached to the frame and includes a plow attached to the rotatable rod by an arm and a joint.

Abstract: A combination of a cable raceway section with a cable exit box, wherein the raceway section is C shaped with one side having a gap in it. A cable exit box at the gap in the side of the raceway section. The box has an opening in one wall overlying the gap in the side of the raceway section and both the gap and the opening are of a length enabling a wide radius turn of cable out of the raceway section and into the box. The box is deeper than the raceway. The box has an open interior defined by sides shaped for supporting a wiring device in the opening, to which wiring device cables exiting from the raceway section are attached.
