  • Patent number: 6598816
    Abstract: A chip detangler is provided for a machine having a discharge trough for collecting fluid containing metal chips. An auger disposed along a longitudinal axis of the trough advances the fluid and chips downstream through an exit area. The detangler preferably comprises a snagging bar fixed relative to the machine and disposed at least partially within the trough to engage nests of chips traveling past the snagging bar. The forces induced by the auger tears apart nests engaged with the snagging bar into smaller, more suitable sizes.

  • Patent number: 6595123
    Abstract: A baler for making rectangular crop bales has a generally horizontally disposed fore-and-aft extending baling chamber. The pickup of the baler is disposed underneath the baling chamber in line with the path of travel of a reciprocating plunger in the overhead chamber. An in-line transfer duct leads generally upwardly and rearwardly from the pickup to the bottom of the chamber. An enclosed crop flow passage is defined from a point immediately behind the pickup to a point located at the opening in the bottom of the baling chamber and presents a forwardmost cutting zone, a packing zone behind the cutting zone, and an accumulating zone behind the packing zone. Cutter apparatus within the cutting zone reduces the crop materials into smaller pieces as they flow through the cutting zone, whereupon a separate packer takes the materials from the rear side of the cutter apparatus and packs them in a downstream direction toward the accumulating zone where they form into a charge.

  • Patent number: 6561878
    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.

  • Patent number: 6547503
    Abstract: A method for manufacturing a pressurized two-chambered container in the form of an aerosol can, in which a housing is provided with an opening that can be sealed tightly by a spray or aerosol valve. A product chamber and a propellant chamber are formed separately fluid-tight from each other by a flexible diaphragm in the housing. The product chamber can be charged with a product which can be release through said valve. The propellant chamber can be charged, on the other hand, with a compressed propellant. The product chamber communicates with the product-release opening. At least one end of a blank is left open to constitute subsequently the housing. The diaphragm is inserted into the blank through the open end, and the blank then is formed into the housing. An edge of the open end of the blank is reformed to narrow it into an integral mouthpiece that accommodates the product-release opening.

  • Patent number: 6546856
    Abstract: A pressing machine, particularly a fast operating pressing machine equipped with a pressing head forced into longitudinal jigging motion in a working range over a bench (46) by an eccenter disk (8), having an eccentric shaft, through a crank arm (9). The pressing head (12) has a lower pressing block (13) removable from the work range above the bench (46) and an upper pressing block (14) arranged slideably in relation to the lower and forced into jigging motion by the crank arm (9) and there is a connecting element (15) joining the lower pressing block (13) to the upper pressing block (14).
