Abstract: A method and system for removing a surface layer contaminated with radioactive and/or hazardous material and subsequently treating the waste to remove contaminants and provide an essentially contaminant-free final effluent. The contaminated material is removed by blasting the surface with a pressurized stream of air and sodium bicarbonate abrasive media, and the media is dissolved in water subsequent to the blasing operation. The resulting waste is treated in a sequence of steps including adjustment of pH, aeration and separation into primarily solid and liquid phases by precipitation of solids, which are removed for appropriate disposal. The primarily liquid phase is successively passed through a particle filter, a granulated activated carbon filter and a polishing unit to produce the clean final effluent.

Abstract: Apparatus for feeding an insulated electrical wire, or the like, axially with respect to a transverse plane in which a single pair of blade cutting edges are supported for movement toward and away from the axis of the wire. Each blade has a continuous cutting edge forming the periphery of an opening through the blade. The wire is advanced a predetermined distance through the aligned blade openings by a pair of conveyors on opposite sides of the plane of the blade edges. The blades are moved in opposite directions to sever a premeasured length of wire from the supply by first portions of each blade edge. The severed wire portion is then moved by the conveyors to a second axial position and the blades are again moved to cause second portions of the cutting edges to pass partially through the layer of insulation, stopping before contacting the conductor. Axial movement of the wire then causes the engaged blades to sever a slug of insulation and strip it partially or fully from the conductor.

Abstract: Apparatus for picking up leaves and other loose material from a lawn or other surface and compacting such material in a bag for disposal. As in prior art apparatus of this type, the material is propelled by a rotating paddle wheel into the forward section of a housing, and from a rear housing section to an auger compactor which feeds the material into a bag positioned upon and against side and end support walls. In the present apparatus, better compaction is achieved by inhibiting rotation of the material within the bag due to rotation imparted by the auger. This action is provided by protrusions on the end and side walls of the support walls which indent the flexible bag as it is filled. As a further safety feature, a skirt carrying pivoted obstruction members prevents objects from being propelled forwardly of the apparatus.

Abstract: Apparatus for severing and stripping a portion of a coating material from an elongated member such as an insulated electrical conductor, or the like, utilizing a pair of overlapping blades having cutting edges formed at the junction of two planar surfaces meeting at an acute angle. The blades are moved relative to one another, radially of the conductor, to cause the cutting edges to move radially partially through the layer of insulation. Relative movement of the blades and conductor axially of the conductor completes the severing of a slug of insulation, all in accordance with the prior art. The present apparatus is distinguished by making the planar surface portions immediately adjacent the cutting edges of the overlapping blades and engaged with the portion of the insulation to be stripped, i.e., the portions of the blades which apply the axial severing force, at equal angles, either 90.degree. or an acute angle, to the direction of relative movement.

Abstract: A device for retrieving and disposing of animal waste in a bag and method of use thereof wherein no parts of the device come into contact with the waste and the operator need not manipulate or otherwise touch the bag after it has contacted the waste. A clean bag is placed over a pair of spring-biased scoop members carried on the distal end of an elongated shaft. The scoop members and bag are placed in a hollow sleeve, open at both ends, where the scoop members are retained with terminal edges thereof in closely adjacent relation by the sleeve walls. As the bag and scoop members are advanced out of the lower end of the sleeve, the scoop members are moved to spaced relation by spring biasing, and the closed end of the bag is placed over the waste. Moving the lower end of the sleeve back over the scoop members turns the bag inside-out, and the waste-containing bag may then be discarded by again advancing the scoop members out of the sleeve.

Abstract: Apparatus for cutting, severing and stripping a portion of a covering layer, such as insulation, from the end of a filamentary core material, such as an electrical conductor. The apparatus includes means for clamping the workpiece to restrain axial movement thereof and a pair of blades which move radially of the workpiece to cut the insulation and then axially to complete the severing operation and strip the severed slug fully or partly from the conductor. The apparatus is powered by a pneumatic cylinder and includes means for automatically varying the clamping force on the workpiece commensurately with the axial pulling force exerted by the blades during severing and stripping. Unique mounting and moving means for the blades and workpiece clamping members are provided to permit pivotal mounting of the blade and clamping member supports while constraining reciprocal movement thereof radially of the workpiece to a linear path.
