  • Patent number: 6634578
    Abstract: A mechanical system that separates bundles of paper and presents the separated paper on a conveyor in a single layer fashion, for further processing. The paper is accumulated in a hopper and fed into the mechanical separating mechanism in a batch mode. When sufficient volume has been admitted to the container, the inflow port is closed and the mechanical separating impeller are activated to rotate in the same direction, imparting bidirectional forces on compacted bundles of sheets or shreds, causing them to deaggregate. Upon completion of the separation cycle, the separated sheets are expelled through an outlet port and conveyed to a drop chute for further singulation, from which the singulated sheets may be deposited onto one or more conveyor belts for sorting.

  • Patent number: 6622950
    Abstract: A separating or deboning machine, for separating soft material such as meat from hard material such as bone, includes a separating chamber through which a flighted auger extends. The separating chamber has a series of perforations in a side wall, through which soft material passes upon rotation of the auger. Pressure is maintained within a flow passage defined by the separating chamber, which forces the soft material through the separations to the exterior of the separating chamber. The separating chamber is preferably formed so as to have a parallel-type wall structure, to provide a high throughput of material. The perforations are in the form of specially configured slots which provide low pressure passages for enabling soft material to pass from the flow passage to the exterior of the separating chamber. The slots are inclined in the direction of auger rotation in an upstream-to-downstream direction.

  • Patent number: 6619575
    Abstract: An apparatus for the continuously recycling of synthetic plastics material, preferably polyester, has a first receptacle (2) for the material in which movable tools (9) are disposed which comminute and/or mix the material. Pre-processed material is conveyed from this receptacle (2) through a vacuum-tightly closable conduit (18) into a second receptacle (19), the interior of which can be evacuated. Within this second receptacle (19) are movable tools (22) for processing the material. The material is conveyed from the second receptacle (19) by means of a screw (30). Another screw (15) is bearingly supported within the channel (18) and the screw volutions of this screw convey the material from the first receptacle (2) into the second receptacle (19). Between the screw volutions (52) of this further screw (15) and the second receptacle (19) there is at least one damming element (39) in the channel (18), which is disposed in the flow of the conveyed material.

  • Patent number: 6616075
    Abstract: A compact and efficient spice grinder having a centrally disposed post configured for engaging a spice seed in the grinding chamber. The spice seed is initially “fractured” by a “pestle-like” seed fracturing structuring at the top of the post. When a user thereafter rotates the dome-like cover of the grinder with respect to the base, spice fragments are grated against interior blades positioned along the sidewall of the chamber adapter/extender. A dome cover is gradually lowered by a user as the spice in the grinding chamber becomes depleted. The grinder is lightweight and may be attached conveniently to a key ring or to a chain and carried as a novelty item.

  • Patent number: 6601788
    Abstract: An apparatus and method are described for creating rubber crumb from rubber vehicle tires. The method provides for the soaking of a vehicle tire in a solvent, removal of the tire from the solvent, movement of the tire by a conveyor to an apparatus that applies physical pressure to the tire, while situated upon a circular screen which allows the physical pressure applied to fragment the tire into its component parts, pressing the rubber components through the screen with any remaining liquid and allowing the non rubber components to be removed for recycling purposes or to be discarded. The apparatus applies physical pressure to separate the rubber and non rubber components from one another.

  • Patent number: 6588689
    Abstract: An apparatus 10 for crushing materials such as rock, ore, coal, stone and the like includes two rolls 16A and 16B which are mounted in parallel to define a gap 18 therebetween. Chunks of material to be crushed are fed by a conveyor 12 into the nip 14 between the rolls. Each roll 16A and 16B is similar and includes longitudinally extending steps provided by outwardly extending faces and smoothly curved surface segments between the steps. When the rolls are counter-rotated at the same speed, the gap 18 is maintained substantially constant and effectively transversely reciprocates in location between limits defined by the outer extremity of the face of a step on one roll being located opposite the inner extremity of the face of a step on the opposite roll. Compared to smooth roll crushing the invention provides for greater reduction ratios to be achieved at slower rotational speeds and using smaller diameter rolls.

  • Patent number: 6588691
    Abstract: A mobile shredding system is used mounted on a vehicle. The system has a hopper, for receiving material to be shredded, a shredder communicating with the hopper, and a holding space for shredded waste into which the shredder feeds shredded material. A bin lifting mechanism with at least one chain onto which a carriage is attached is mounted on a side of the vehicle. The carriage has an engagement mechanism for attaching a bin and the chain is movable by means of a drive mechanism from a lowered position, in which the carriage is adjacent the ground on which the vehicle is standing, and a raised position, in which the carriage is adjacent an inlet of the hopper and the contents of the bin are emptied into the hopper via the inlet. The carriage has a weight measuring mechanism such as a load cell incorporated therein to measure the weight of the bin when the bin is attached to the engagement mechanism. The system further has a weight indicating display, and also a electronic storage of the measured bin weight.

  • Patent number: 6585177
    Abstract: The data destruction machine is a desk-top, portable unit with a short (under 10 second) cycle time, pluggable into a wall outlet. Upon insertion of a disk (such as a CD or split DVD) into the machine, which is fully automatic, data is removed. The machine converts the data-storage layer into residue consistent with security destruction standards from which no data is retrievable. A single machine may be used for declassifying CDs and split DVDs. Splitting DVDs in preparation for inserting them into the data destruction machine may be accomplished quickly and simply.
