Abstract: A method for recovering NiSO4.6H2O crystals from a nickel rich organic phase is provided. The method includes contacting a nickel rich organic phase with an aqueous strip solution of sufficient H2SO4 concentration to extract nickel from the organic phase and of sufficient Ni2+ concentration to precipitate NiSO4.6H2O crystals and form a nickel lean organic phase. Also provided are methods for recovering NiSO4.6H2O crystals that include preceding processing steps, including low temperature pressure oxidation (LTPOX) autoclaving of a nickel sulphide concentrate to afford a pregnant leach solution (PLS).

Abstract: A device for checking the quality of extensible film for wrapping purposes available in reels, operatively associable to a wrapping machine. The device supports at least one reel of extensible film, including at least one storage memory of a plurality of wrapping programs of a palletized load, each characterised by different operating parameters to carry out the wrapping operation, and detects at least one parameter representative of the quality of the film on the reel and measures instant by instant, the present diameter of the reel. An electronic processor, operatively associated with the storage memory, is provided suitable for selecting and/or changing a given wrapping program according to at least the parameter representative of the quality of the film on the reel. A method to inspect the quality of the packaging stretch film available in reels.

Abstract: The present invention relates to a head for wrapping loads, particularly for palletized loads, including at least one support framework for at least one reel of extensible material, the support framework including at least one pair of plates connected to each other through a longitudinal plate extending along a longitudinal axis (x-x) of the framework, the reel being supportable by the support framework parallel to the axis (x-x) and the extensible material, in use, can be unwound from the at least one reel along a delivery plane (P), at least means for the return of the extensible materials supported by the at least one support framework along the longitudinal axis (x-x). The wrapping head includes at least one group for folding the extensible material, downstream of the return means, the folding group being predisposed, in use, to engage and fold at least one peripheral portion (p) of such extensible material on itself, hence obtaining a double layer band (F) of such extensible material.

Abstract: A system for wrapping sets of products with a stretch film has a first conveyor belt with the incoming products, a second outgoing conveyor belt with the products wrapped in the stretch film, and one or more devices for wrapping the products with a stretch film, each device being provided with a handling robot with a handling end, to which a wrapping and gripping assembly is fixed that includes a wrapping head for wrapping the stretch film and gripping elements for gripping and rotating the products while the stretch film is wrapped.

Abstract: A memory having variable interleaving levels and associated configurator circuit which provides for the optimum level of interleaving based on the memory configuration. A number of independently addressable storage modules may be installed in the memory, the modules having various capacities which are usually multiples of a basic capacity. The configurator circuit receives a first field (ALOW) of least significant bits from the address for the desired memory entry and a second field (AHIGH) of bits of greater weight from the memory address. According to the number of the modules present in the memory and their capacities, the configurator circuit generates a module selection signal for selecting from the various modules present and a plurality of signals (MBIT) representing the memory module address bits. The configurator circuit thereby configures the memory with the highest levels of interleaving allowed by the capacity of the modules installed and properly addresses the selected module.
