  • Patent number: 6886615
    Abstract: A portable power planer for planing the top surface of a workpiece. The portable power planer includes a base, which defines a reference surface, a cutting blade, which defines a cutting plane, and a setting mechanism may be employed to prevent a distance between the reference surface and the cutting plane from being adjusted to a dimension that is smaller than a height dimension that is selected from a group of predetermined dimensions. The setting mechanism includes first and second stop members, one being coupled to the base and the other being associated with the cutting blade. One of the stop members includes a plurality of differently dimensioned sectors or contact points that may be selectively positioned inline with the other stop member to inhibit movement of the cutting blade toward the base if the dimension therebetween is equal to a dimension associated with a given one of the contact points.

  • Patent number: 6883422
    Abstract: A binding arrangement and a process for the control of a binding arrangement is described that includes a binding material delivery arrangement, a cutting arrangement and a braking arrangement for the binding material, where the brake can be controlled and generates a variable braking force. To improve the binding process for harvested crop, brakes for the binding material are applied with which a binding material tension is generated or is increased to cause the binding material to be retarded during the binding process in opposition to the flow of the binding material. The brakes are controlled such that only a low binding material tension is caused at the beginning of the binding process to increase the tension to as large a value as possible during the continuing binding process and to reduce the tension upstream of the cutting arrangement again at the end of the binding process.

  • Patent number: 6874411
    Abstract: A method of and an apparatus for compressing the grinding sludge, which is effective to compress the grinding sludge to provide an intended rigid briquette even though the grinding sludge contains ground chips of hardened iron and/or steel materials and an oil-based coolant and also to facilitate reuse of the briquette (B1) as material for production of steel. The grinding sludge containing the oil-based coolant and hardened component parts such as steel component parts that are used in bearings is compressed. To this end, the grinding sludge produced from a grinding line (1) is filtered by a filtering unit (4) to provide a concentrated sludge which is subsequently compressed by squeezing by a briquetting machine (5) to provide the briquette (B1). The briquette B1 so obtained can be reused as steel material. The coolant separated from the grinding sludge during filtering and squeezing is returned to the grinding line (1) through recovery passages (7, 8).

  • Patent number: 6874412
    Abstract: A bale shape monitoring system for a round baler for detecting a misshapen bale during bale formation. The system includes a pair of spaced apart rollers mounted to a movable member located within the bale-forming chamber, and which are normally engaged with spaced apart baler belts when the bale has a uniform diameter in the vicinity of the rollers. A rotation sensing arrangement detects the rotation of the rollers, caused by engagement of the rollers with the belts during normal bale formation. In the event the bale is formed with a lesser diameter in the vicinity of one of the rollers, the associated belt moves out of contact with the roller, and the lack of roller rotation is sensed so as to provide a signal to the operator to steer the baler to supply crop material to the lesser diameter area of the bale. Once a uniform diameter is again obtained, both rollers continue to rotate so as to indicate to the operator that the bale has a uniform diameter.

  • Patent number: 6871583
    Abstract: The method of the present invention for handling scrap tires, includes a step of providing a compacting apparatus to a scrap tire generator, such as a tire retailer. Before compacting the tires, the tire can be marked with a unique identifier assigned to every tire generator. By marking the scrap tires with a unique identifier, the scrap tires can be tracked on their way to the final destination. The compacting apparatus provides volume reduction of the scrap tires individually into a form that can have a reduction of at least fifty percent of original cubic volume. The tires can be pinched to maintain the compacted tire in the compacted form and prevent the compacted tire from regaining its original shape. The compacted scrap tires can be accumulated inside a tire collection enclosure, such as a trailer or dumpster. The collected tires can be transported with much more weight efficient loads of the tires to a transfer station, a recycling facility, or an end user.
