Abstract: An assembly is disclosed for mounting on an inclined planar surface, a light fixture suspended by at least one fixture suspension cable and provided with at least one power cord. In general, the mounting assembly comprises a mounting base, and first and second suspension means. The mounting base is for attachment to a planar structure disposed relative to a reference plane, and includes at least one power cord suspension aperture. The first suspension means is operably associated with the mounting base and is adapted for attachment to one end of the fixture cable. The second suspension means is mounted through the power cord suspension aperture and is adapted for attachment to a portion of the power cord. The first suspension means and the second suspension means each permit pivotal movement of the fixture suspension cable and the power cord, respectively, that is, relative to the mounting base, and the first suspension means and the second suspension means are operable independent of each other.

Abstract: A pneumatic carrier terminal in a preferred embodiment includes a movable horizontal tray alignable with a horizontal pneumatic tube connected to the terminal. A carrier sealing ring is provided on the end of the tray and is aligned with the tube. The trailing end of a received carrier resides in the ring which surrounds the carrier's gasket. Stationary, two-stage cam apparatus within the terminal engages and pushes a carrier out of the ring when the tray is moved out of the terminal to present the carrier. Other stationary cam apparatus within the terminal engages and pushes a carrier into the ring when the carrier is replaced and the tray is retracted from the presentment position. The ring operatively seals one end of the carrier to the pneumatic tube to positively insure carrier flight when the terminal is pressurized. Alternate cam apparatus is disclosed.
