Patent number: 6783007Abstract: A device enabling the timely removal and subsequent recycling of residues remaining in a pouring chute through which the load of a cement from a mixing drum of a mobile delivery vehicle was discharged. A strainer on a movable arm attached to the vehicle is placed under the chute to receive an effluent which results from spraying the inside of the nozzle with water. Solid particulates are retained by the strainer and a slurry which emerges from the strainer is pumped into the mixing drum, allowing the separated materials to be recycled when the vehicle returns to its base.Type: GrantFiled: March 12, 2002Date of Patent: August 31, 2004Inventor: Cataldo S. Arbore

Patent number: 6763949Abstract: A waste recovery station for a beach cleaner for recovering waste raked up by a beach cleaner. A waste recovery station for a beach cleaner includes a pair of station members arranged in parallel with each other through a required spacing. Each station member is provided with a pair of support posts with a foot such as, for example, a circular or square flat plate fixed to a lower end of each support post and is also provided with a guide member fixed to upper ends of the support posts. In the guide member, a longitudinally intermediate portion is formed as a horizontal portion and front and rear end sides are formed as slant portions and are bent downwardly at an obtuse angle. The beach cleaner A is lifted by the guide members while passing between the station members, whereby waste caught on rakes is allowed to drop onto the sand.Type: GrantFiled: October 4, 2001Date of Patent: July 20, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takashi Ohzeki, Yoshihiro Kimura, Yasuji Hashimoto, Yoshinobu Itani, Takashi Shinozaki

Patent number: 6726025Abstract: A system and method for sorting recyclable materials is portable, modular, and easy to install and/or remove. Generally, a variety of sorting equipment is placed upon a portable platform that may be loaded or unloaded from a roll-off truck. When at the desired location, the portable platform may be removed and the sorting equipment set up for use. The sorting equipment may include an infeed conveyor, a sorting conveyor, and a variety of automatic sorting equipment such as an aluminum blower, a magnet separator, and an eddy-current separator. The platform may be simply placed on the floor or ground at the desired location or it may be elevated by a plurality of supports.Type: GrantFiled: March 4, 2002Date of Patent: April 27, 2004Inventor: Michael Huskey

Patent number: 6722505Abstract: Aggregate mixtures such as dirt, sand, rock, concrete, etc. are separated into piles according to size by continuous agitation of the mixture and by gravitational and centrifugal forces exerted thereon. A container for the material, such as the bucket of a backhoe, has the bottom thereof at least partially open. An adjustable, hydraulically-driven rotating disk attaches to and covers the open portion of the bottom of the container, the combination having a gap, or a selected spaced-apart relationship, between the stationary container and the rotating disk. The mixture is agitated by the rotating disk and by contact with the other particles in the container. Particles smaller than the selected gap distance are thrown out through the gap between the disk and the open portion of the container by centrifugal force. Material larger than the selected gap size remains in the container.Type: GrantFiled: January 31, 2002Date of Patent: April 20, 2004Inventor: Herbert S. Kobayashi

Patent number: 6712218Abstract: A soil screening device includes a screen frame having a screening surface, and a supporting frame. The supporting frame may have rearwardly disposed rigid uprights supporting the screen frame. The screen frame is pivotally mounted to a first upper member mounted at an upper end of the uprights, for pivoting between a lowered position and an elevated position. The supporting frame has a base frame extending forwardly of the uprights. Upper members of the base frame have at least one wedge selectively positionably mounted thereon, for example atop the upper member of the base frame. The wedge or wedges are positionable to engage a lower edge of the screen frame when in the lowered position bearing down on an upper inclined surface of the wedge or wedges. The wedge or wedges are selectively positionable relative to the upper members of the base frame so as to selectively adjust an angular orientation of the screen frame relative to the uprights.Type: GrantFiled: July 31, 2002Date of Patent: March 30, 2004Inventor: Klaas Nierop

Patent number: 6698594Abstract: A mobile screening machine with a frame on tracks, having a hopper and a main conveyor mounted to a frame. The main conveyor conveys particulate matter from the hopper to a screening device positioned beneath the upper end of the main conveyor. The particulate is screened into three grades of coarseness, with the coarsest falling into a chute, the middle coarseness falling onto one lateral conveyor and the finest falling onto an underscreen conveyor, which preferably is driven downhill onto another lateral conveyor. The tracks permit the machine to be driven around the work site and onto and off of a trailer, and the entire machine can be remotely controlled. The downhill conveyor permits loading of the hopper from both sides of the frame.Type: GrantFiled: March 18, 2002Date of Patent: March 2, 2004Assignee: Ohio Central Steel CompanyInventors: Douglas J. Cohen, Steven A. Cohen
