Abstract: THIS invention relates to a method of disposing of residues from the comminution and processing of ores. The method includes the steps of classifying the processing residues into a water permeable sand fraction and a tailings fraction and depositing the tailings fraction and the sand fraction to form a multilayer structure contained by at least one containment wall (14) with the sand fraction forming continuous channels (12) through the tailings fraction (10) to allow water contained in the tailings and sand to flow by gravity, through the sand channels, to water discharge points (16), and recovering the water (18) from the water discharge points.

Abstract: Some embodiments are directed to a shaped charge liner including an apex end and a base end and defining a main liner axis that passes through the apex and base ends, the liner being rotationally symmetric about the main liner axis wherein the liner has discrete rotational symmetry about the main liner axis.

Abstract: An oil and gas well shaped charge perforator capable of providing an exothermic reaction after detonation is provided, comprising a housing (2), a high explosive (3), and a reactive liner (6) where the high explosive is positioned between the reactive liner and the housing. The reactive liner (6) is produced from a reactive composition which is capable of sustaining an exothermic reaction during the formation of the cutting jet. The composition is a pressed i.e. compacted particulate composition comprising at least two metals, wherein one of the metals is present as spherical particulate, and the other metal is present as a non-spherical particulate. There may also be at least one further metal, which is not capable of an exothermic reaction with the reactive composition, present in an amount greater than 10% w/w of the liner. To aid consolidation a binder may also be added.

Abstract: A method is provided for dynamically adding customized advertisements with media content on digital media storage devices. A user may provide identification data to an automated machine or salesperson selling the media content at a retail location. Based upon the identification of the user, advertisements may be selected to be added to the media content. The selection of advertisements may be based upon previous transaction data, the genre of the media content, or characteristics identified for the user. Users may also select to change the quantity of advertisements to view based upon fees paid by the user for the media content. The user may pay additional fees to view less advertisements and the user may pay fewer fees and have more advertisements included with the media content.

Abstract: A multi-regime continuously variable ratio transmission has a transmission input shaft, a transmission output shaft, and a ratio varying unit having a rotating input and a rotating output, the rotational axes of the input and the output being coaxial. A shunt having first and second epicyclic gear sets is connected across the ratio varying unit. One gear set has an input driven by the input shaft and an input driven by one side of the ratio varying unit and the other gear set has an input from the first gear set and an input from one side of the ratio varying unit. The gear sets rotate about a common axis and are offset with respect to, and parallel to, the rotational axes of the input and output of the ratio varying unit. A clutch is operable to selectively connect the output of the second gear set to the output shaft.
