Title: Method for processing sulfide minerals and concentrates
Inventor: FOKIN KONSTANTIN SERGEEVICH
IPC: B01D53/56
Filed: 2003-04-16
Abstract: The method is referred to hydrometallurgical process and serves for recovery of nonferrous, rare and precious metals from sulfide minerals and concentrates. The invention is aimed at creating conditions for the most complete extraction of metals, preventing formation of elementary sulfur. The objective is attained by means of the following: the hydrometallurgical method of sulfide minerals and concentrates processing, which involves sulfide minerals oxidation in aqueous medium using nitrogen oxides, envisages that the sulfide materials containing slurry are subjected to oxidation of the sulfide and the oxidation is realized under controlled conditions of the slurry acidity, i.e. with constant neutralization of sulfuric acid formed as a result of the sulfides oxidation, moreover, sulfuric acid is neutralized to acidity level, at which no formation of elementary sulfur occurs, while natural or artificial substances, such as CaC03, MgC03, Ca(OH)2, CaO, NaOH, CaHP04 etc., are used as acidity neutralizers; the choice of a specific neutralizer is dictated by the necessity of formation of slurry neutralization products with assigned physicochemical properties: filterability, slurry thickening, arsenic substance insolubility, non~toxicity and other required properties. Oxidation of sulfide minerals is realized under agitation providing sufficient mass exchange and efficient occurrence of chemical reactions. Oxidation is realized in the temperature range of 20-90~C, mainly in the range of 65-85~C. The liquid-to-solid ratio may vary from 1:1 to 5:1, depending on effectiveness of the required precipitate formation and proceeding of sulfide oxidation reactions. Nitric and nitrous acids, as well as their oxides, mainly nitrous acid, HN02, and its oxide, N203, are used as oxidizing agents. Regeneration processes of NO to N203 are also described.

Patent CA-2538077-A1 (CA)
Inventor: CHINI ALESSANDRO
IPC: H01L31/072
Filed: 2004-09-09
Abstract: A process for fabricating single or multiple gate field plates using consecutive steps of dielectric material deposition/growth, dielectric material etch and metal evaporation on the surface of a field effect transistors. This fabrication process permits a tight control on the field plate operation since dielectric material deposition/growth is typically a well controllable process. Moreover, the dielectric material deposited on the device surface does not need to be removed from the device intrinsic regions:  this essentially enables the realization of field-plated devices without the need of low-damage dielectric material dry/wet etches. Using multiple gate field plates also reduces gate resistance by multiple connections, thus improving performances of large periphery and/or sub-micron gate devices.

Patent CA-2548886-A1 (CA)
Inventor: CANAN STEVEN M
IPC: F25C5/08
Filed: 2006-05-30
Abstract: A circuit is disclosed for detecting and eliminating the buildup of snow and/or ice on the viewable face of an LED traffic signal lens. The circuit measures the ambient temperature within the LED signal, and when the temperature falls to a level where snow and/or ice accumulation can occur, the circuit begins looking for snow and/or ice buildup on the lens of the LED signal. An infrared LED transmits a signal which is reflected when snow or ice is present on the lens of the traffic signal. When the reflected signal is received by an infrared receiver, it sends a signal to a microcontroller, which analyzes the signal to determine if it is a valid signal. If it is, a heater is turned on until the ice and snow are removed.
