Abstract: A water treatment system for a poultry chiller including a chiller tank is described herein. The system includes a float holding tank at a downstream section of the chiller tank; a fan at the downstream section of the chiller tank that is configured to blow float formed on a surface of the water in the chiller tank into the float holding tank; and a float removal mechanism at the float holding tank that is configured to remove the float from the float holding tank. Related methods are also described.

Abstract: An improved audio-visual apparatus for projecting visual information segments carried by a transparency holder in an audio-visual cartridge, and for reproducing corresponding narrative and control information recorded on a movable storage medium carried by the cartridge. The apparatus includes an optical projector for projecting a selected one of the visual information segments onto a screen and a first drive mechanism for supporting the holder and selectively driving it to align specified visual segments with the optical projector. A second drive mechanism supporting the storage medium and selectively moving it independently of the holder to permit reproduction of recorded information is provided, and a playback device is mounted in operative relationship with the storage medium to produce signals corresponding to the stored information.
