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.

Abstract: An apparatus for use in a press machine eliminates the free clearances present between the threaded portions of a screw and adjustment nut assembled in a shutheight adjustment mechanism. A hydraulic assembly directs a pressurized fluid against an outer periphery of the adjustment nut to effectively compress the adjustment nut and cause its threaded portion to be displaced into interlocking engagement with the threaded portion of the screw. Alternatively, the hydraulic assembly may be arranged to hydraulically pressurize an interior space of the screw to effectively expand the screw and cause its threaded portion to be displaced into interlocking engagement with the threaded portion of the adjustment nut.

Abstract: Apparatuses and methods for planarizing a microelectronic-device substrate assembly on a planarizing pad. In one aspect of the invention, material is removed from the substrate assembly by pressing the substrate assembly against a planarizing surface of a planarizing pad and moving the substrate assembly across the planarizing surface through a planarizing zone. The method also includes replacing at least a portion of a used volume of planarizing solution on the planarizing surface with fresh planarizing solution during the planarization cycle of a single substrate assembly. The used planarizing solution can be replaced with fresh planarizing solution by actively removing the used planarizing solution from the pad with a removing unit and depositing fresh planarizing solution onto the pad in the planarizing zone.

Abstract: The invention relates to a method and a device for forming a corner bounded on three sides from a flat plate part, in particular sheet metal, whereby the side edges adjacent to the corner are folded back across a major part of their longitudinal extension parallel with the flat plate part and shaped on a curved path in the region in which the corner is to be formed from the folded-back side edge to the plane of the flat plate part. The pre-formed blank is then pressed at the curved transition region by means of at least one roller system (42), spanning the corner region (10) between the side edges, against a tool (16) and the corner shaped by forming the material and optionally trimmed in a cutting device.

Abstract: A hay conditioning apparatus includes a first roller which is rotatably mounted in a fixed mounting and a second counter-rotating (compression) roller which is rotatably mounted in connection with a moveable mounting. The compression roller is in rolling contact with the first roller and is adapted to receive pre-cut hay therebetween for conditioning. The moveable mounting allows the compression roller to be displaced relative to the first roller as the hay passes between the rollers and also includes a hydraulic cylinder for applying a compression force to the compression roller. As the pre-cut hay passes between the rollers, it is subjected to a predetermined compression force sufficient to substantially flatten any green nodes on the hay and thereby accelerate drying of the hay.
