Abstract: A mobile, self-contained, environmentally safe, cleaning apparatus, including a supply of recycleable cleaning fluids and devices for heating, filtering and pressurizing such fluids for removing, capturing and packaging for safe disposal oils, dyes, fibers, lead paint and contaminated hazardous wastes, with the apparatus equipped with a water tank, a liquid ring pump adapted to create a wet vacuum recovery system, a water heater, a waste particle/liquid separator, a demister filter, and a retractable combined fluid supply and vacuum recovery umbilical cord for attachment to external remote cleaning devices.

Abstract: A portable cleaning apparatus including means for suctioning spent cleaning fluid and recoverable debris, dirt and contaminates from the surface being cleaned, including a portable cart housing a auger type tumbler adapted to received vacuumed debris and wherein the tumbling debris is subject to blast spray cleaning liquids. A recovery chamber at one end of the tumbler provides a closed trap door that retains cleaned debris within the cart until the vacuum suction is disrupted at which time, the trap door is opened, the debris is then deposited, thoroughly cleaned onto the supporting surface.

Abstract: A decontaminating apparatus for cleaning radioactive contaminated surfaces and recovering for disposal the contaminated material, including a first recovery unit comprising a vacuum creating source in association with a second recovery unit that filters and demists the vacuum recovered contaminated material, and a third recovery unit that initially vacuum recovers the contaminated material and separates the same into fluid and air borne contaminates. The second and third recovery units each having a critical mass control responsive to the volume of contaminated material vacuumed from the surface being decontaminated.

Abstract: A lid-to-container locking assembly for lock sealing containers utilized in the transporting, storage and disposal of low level radioactive contaminated material. The locking assembly gives visual indications of a locked, sealed condition of the container through the utilization of a closure element that is ensconced in a latched position upon the lid to be secured, as well as to the container to be sealed. Detachment of the closure element at either of these points of its locking engagement with the lid and/or container will visually indicate an open and unsealed condition.

Abstract: A sealed cabinet-like work booth for use in removing contamination from reusable parts and tools. The front wall of the work booth provides a transparent inclined viewing window above sealed glove ports, with the interior of the work booth being accessible through pneumatic side doors. An air plenum provides an inlet for ambient air and cooperates with a filtered exhaust for maintaining a continuous current of air directed upon the interior surface of the viewing window for preserving an unobstructed view of the interior of the cabinet.

Abstract: A device for use in waste containers wherein the waste is packed, compressed and secured in its compact state within the container. The device comprises a rack consisting of a pair of telescoping cross bars with the opposite ends of said cross bars provided with yieldable anti spring back retainers that are adapted to be received and locked in guide channels carried by confronting interior wall surfaces of the waste container. These channels are complete with cooperating yieldable or pivotal anti spring back retainer clips positioned interiorly of the channels in the path of the respective ends of the rack's cross bars so as to secure the same in a latched depressed position against the compacted waste material within the container.

Abstract: An apparatus for removing surface material such as contaminated textures including asbestos and the like from walls and ceiling structures, and for preventing the removed material from escaping into the ambient environment. The apparatus provides a portable shroud enclosing a material removal member which could be a shredding head or an emitter of sonic, ultrasonic or ultraphonic signals. A liquid or coagulant spray mainfold will operate in close proximity to the material remover and is utilized to capture and retain air borne microscopic particles. The material remover and spray manifold are mounted on a power carrier which is adapted to reciprocally move these elements within the shroud and above a material receiving hopper. A vacuum recovery system acts in cooperation with the hopper to retrieve and retain for disposal the removed surface material.

Abstract: A waste compactor utilizing the combined forces of compression and vibration for reducing, leveling and compacting waste within a container. The pressure force is expelled through a guided hydraulic ram assembly, the pressurized movement of which is coordinated with an applied vibrating energy developed through a mechanical vibrator and/or sonic frequency emitter, the rate and intensity of which encompasses a varying range. The sonic vibrating energy generator may be carried by and movable with the compacting ram or it may be embedded in the base platform of the compactor.

Abstract: A latch assembly for a removable lid container that includes a cam lock assembly. The container to be sealed provides a removable lid that has a depending peripheral-defining flange which has hingedly attached thereto a cam lock lever that includes a cam bar which is adapted to be rotatably positioned beneath a cam lock carried by the juxtapositioned side wall of the container when the lid is placed thereon and secured thereto. The cam lever provides a means which will receive a locking pin that cooperates with a receptive structure formed on the side wall of the container by which the cam lock may be secured in a latched position.

Abstract: A lock for the lid of a container used in disposing of low specific activity, minimally contaminated waste material, with the lock so constructed so as to be releasable or permanent, and to give visual indication of either condition. The lock structure includes a lid contacting member that may be releasably or permanently connected to a latch plate insertable into a restraining member carried by the side wall of the container.

Abstract: A combination vacuum and spray head for a pressurized cleaning apparatus adapted especially for use upon open grating. The structure includes a vacuum head housing, a shielded spray head that provides a plurality of downwardly, diagonally directed spray nozzles for directing a stream of fluid against the opposite sides of parallelly extending grate slats.
