Abstract: The present invention relates to a hierarchical artificial neural network (HANN) for automating the recognition and identification of patterns in data matrices. It has particular, although not exclusive, application to the identification of severe storm events (SSEs) from spatial precipitation patterns, derived from conventional volumetric radar imagery. To identify characteristic features a data matrix, the data matrix is processed with a self organizing network to produce a self organizing feature space mapping. The self organizing feature space mapping is processed to produce a density characterization of the feature space mapping. The self organizing network is preferably completely unsupervised. It may, under some circumstances include a supervised layer, but it must include at least an unsupervised component for the purposes of the invention. The "self organizing feature space" is intended to include any map with the self organizing characteristics of the Kohonen Self Organizing Feature Map. The frequency vector of a CAPPI image that has been derived is a data abstraction that can be displayed directly for examination. In preferred embodiments, it is presented to a classification network, e. g. the standard CPN network, for classifying the density vector representation of the three dimensional data and displaying a representation of classified features in the three dimensional data. A novel methodology is preferably used for incorporating vigilance and conscience mechanisms in the forward counterpropagation network during training.

Abstract: An adjustable and extendible sleeve which is attachable to the pre-existing sun visor of a vehicle. The sleeve slides over the Existing sun visor allowing it to be slid along the same plane, extending the existing visor in either horizontal position blocking out the sun beyond the normal range of the existing sun visor. The sleeve is basically an envelope with the two ends cut off. The one end is shaped as to block the sun from entering the vehicle from above the central rear view mirror, thus allowing for safer operation of the motor vehicle with out a substantial additional cost and without blocking or obstructing vision through the mirror. On the top of the sleeve the folded seam would be much shorter than the bottom allowing greater travel along the horizontal plane without having to unsecured the visor from the fastening clips provided by the manufacturer. The material would be either plastic, paper, bristle or cardboard and the surface of the MOTOR VEHICLE SUN VISOR EXTENSION can be used as advertising space or corporate logo.

Title: Method for treating mineral material having organic carbon to facilitate recovery of a precious metal
Inventor: SIMMONS GARY L
IPC: C22B11/02
Filed: 1995-11-14
Abstract: Provided is a process for treating refractory precious metal-containing ores, particularly gold-bearing ores, to reduce the ability of organic carbon to interfere with recovery of the precious metal. The ore may also contain sulfide materials with which the gold is associated and from which the gold is difficult to separate. The ore is comminuted (104) to a size at which at least about 80 weight percent of the ore is smaller than about 40 microns in size. The comminuted ore is then slurried and subjected to pressure oxidation (108) at severe operating conditions. The treating temperature is greater than about 190 degrees C. When sulfide minerals are present, substantially all of the sulfide sulfur must first be oxidized prior to obtaining significant benefit from the treatment of the organic carbon. Greater than about 96 % of the sulfide sulfur must be oxidized. Neutralization (114) occurs after the oxidation treatment to prepare the slurry for CIP cyanidation (118) from which gold is then recovered (128).

Abstract: ABSTRACT The invention provides a packer wheel to be towed behind agricultural equipment such as an air seeder, the wheel being used to pack the soil in which seed or fertilizer has been placed.  The packer wheel includes a hub and a body extending from the hub to a peripheral wall.  A plurality of circumferentially spaced slots extend from the peripheral wall inwardly of the wheel body. Adjacent slots define therebetween a fin which, due to the slots, is somewhat flexible.  As the packer wheel rotates the fins will flex slightly, but enough to cause any mud, soil or debris that built up thereon to break away so that the packer wheel remains relatively clean, even in muddy conditions.  The slots are shaped so that any mud or debris that builds up therein is automatically forced axially outwardly of the slots as the wheel rotates.

Filed: 1996-05-13
Abstract: The description relates to an optical character generator (ZG) suitable for reproducting raster image data in grey-scale displays. Integrated light sources (LED) in LED arrays are aligned to form a printed line. A means for its control (IC) is allocated to each LED array. Groups of such means (IC) are formed, in which information is shifted for the switch-on time of all LEDs of a group starting with the first IC to the next ICs. The connection of the individual ICs together for transmitting the data is made directly between the ICs by bonding. There is a special ramp circuit (OPV) to prevent current surges when the LEd is switched on. The information and energy are transmitted to the IC groups via a flat unit (FBG) extending along the character generator (ZG). Special busbars ensure that the power is reliably taken to the LED  arrays.
