Abstract: A system is described for the treatment of aircraft toilet waste water to permit discharge of the treated water to the atmosphere during flight, utilizing the pressure differential that is created between the aircraft's cabin pressure and the external atmosphere. The system includes a filter to remove suspended solids and other contaminants from the waste water, and may also include means to purify the water to potable water standards and means to recirculate the treated water for reuse on the aircraft.

Abstract: A method and system are described for the treatment of aircraft toilet waste water to permit discharge of the treated water to the atmosphere during flight, utilizing the pressure differential that is created between the aircraft's cabin pressure and the external atmosphere. The system includes a filter to remove suspended solids and other contaminants from the waste water, and may also include means to purify the water to potable water standards and means to recirculate the treated water for re-use on the aircraft.

Abstract: A removable, self-powered trash compactor particularly suited for aircraft tray carts. The compactor includes a rechargeable battery to power a motor that drives a screw drive connected with a scissor type extension linkage attached to a platen designed to permit the passage of liquids around said platen to minimize pressure exerted on walls and floor of container, carts and carriers. The food service tray guides support a plastic or fiberboard sheet to restrain resilient waste matter from returning to its original shape and permitting a disposable flexible liner to interfold underneath the compactor and surround the compactor until the first cycle wherein the liner unfolds and encompasses the cart, carrier or container space, thereby obtaining the compactor to support the disposable liner and permitting the fitting of an interfolded cover over the entire compactor inside the liner to permit the compactor to compress waste and keep waste matter from contact with the compactor mechanisms.

Abstract: An emergency escape apparatus for speedily evacuating workers or others from a high level platform or the like comprising a longitudinally folded tubular escape chute slidably connected to an angularly disposed cable, the chute being held in folded condition by a cover that may be speedily opened to release the chute for unfolding deployment down and along the cable, and the chute being of multisleeve construction with the outer layer of fire resistant material. The apparatus may be used for other purposes than emergency escape, for example as a slide chute in an amusement park.
