Title: Packaging memory image files
Inventor: SHIPTON PETER DUNCAN
IPC: G06F9/445
Filed: 1999-03-30
Granted: 2003-10-14
Abstract: In typical Java and other interpreted programming language environments, the code is stored in ROM in a semi-processed state, .class files containing byte codes. When the device is turned on, a virtual machine resolves references and links the .class file in RAM to permit desired applications to be run. In the invention, the .class files are further pre-processed to select the data which will not change or require updating. This data is packaged into memory image files containing internal data pre-linking this data. The memory image files are stored in ROM and are accessible from ROM by the virtual machine at runtime. Only elements that will be updated, such as the objects themselves, must be instantiated in RAM at runtime. This reduces the amount of RAM needed to run the application. In an environment with memory constraints, the reduction in RAM  requirements permits more RAM to be made available for application use.

Inventor: OOMMEN BASANTKUMAR JOHN
IPC: G06F17/30
Filed: 1999-07-30
Granted: 2012-10-23
Abstract: This invention provides a novel means for creating a histogram for use in minimizing response time and resource consumption when optimizing a query in a database, and other like structures, the histogram being created by placing ordered elements into specific range until the next element to be considered for inclusion in the range is a predetermined distance from the (generalized) mean value associated with the elements within the range, whereupon that next element is placed in the following range. Similarly, the following ranges are closed when the next element to be considered for inclusion in the range is greater than a predetermined distance from the (generalized) mean value associated with the elements in that range, whereupon that next element is placed in the following range. For each range, the location and size of the range is recorded with, for example, the mean value, the slope or other attribute characterizing one or more elements in the range. The invention has also applications in pattern recognition, message routing, and in actuarial sciences.

Title: Separation of minerals
Inventor: SENIOR GEOFFREY DAVID
IPC: B03B1/00
Filed: 2000-03-02
Granted: 2012-05-15
Abstract: A process for floating fine particles containing metal values of an iron-bearing sulphide mineral ore including the steps of conditioning the aqueous pulp of ore at a pH of between about 7 and about 10 with a reducing agent which is preferably oxy--sulphur compound which dissociates to form oxy-sulphur ions having the general formula:-S n O y z-where n is greater than 1; y is greater than 2; and z is the valance of the ion. A suitable collector is then added to the conditioned aqueous pulp to further condition the pulp and the pulp potential of the pulp raised to a sufficient level for the collector to adsorb onto the sulphide mineral ore. Gas is then bubbled through the aqueous pulp to subject the pulp to froth flotation. The froth from the flotation process is recovered to produce a concentrate of fine sulphide mineral and other metal values.   By conditioning the aqueous pulp at a pulp potential which dissolves the iron hydroxide film from the surface of the metal sulphide inclusions in the ore and subjecting the ore to froth flotation at a suitable pulp potential before the iron hydroxide can reform, the recovery of metal values in the fine ores can be greatly enhanced.
