Patent CA-2397221-A1 (CA)
Title: Chemical-mechanical process to reduce the contamination caused by gases and products resulting from the combustion of fossil fuels, petroleum and its by-products
Inventor: VIDAL FERNANDEZ RAFAEL
IPC: F01N13/02
Filed: 2002-08-08
Abstract: A chemical-mechanical process whereby the contamination occurring through combustion of fossil fuels, petroleum and its by-products is reduced by altering the final chemical composition of the resulting gases; by reducing the totality of gases: SOx, NOx, VOC or HC, CO and CO2 and particle matter comprising the effluent and releasing a greater quantity of oxygen into the atmosphere than the one resulting post-combustion. A liquid chemical solution intervenes in this process, comprised of distilled water, sodium bicarbonate and urea, a mechanical device containing it that allows this solution to enter into contact with the gases from combustion, washing them, and also one or several filtering elements that are part of the mechanical device, comprised of a polymeric hydrocarbon fiber that chemically reacts in the presence of carbon, which produce the chain reaction of the resulting harmful gases in internal combustion engines, boilers, stacks, stationary or mobile sources, reducing their emissions and retaining the greater part of the solid elements and hydrocarbons inside the device and returning a gas effluent into the atmosphere that is richer in oxygen and has a very small amount of the remaining gases and particle matter than what was contained in the original effluent.
Patent CA-2397515-A1 (CA)
Title: Electrode component thermal bonding
Inventor: MCBENNETT MICHAEL C
IPC: H05H1/34
Filed: 2002-08-12
Abstract: An electrode for supporting an arc in a plasma arc torch is provided and includes an emissive element for supporting the arc, which may be formed of hafnium; a relatively non-emissive member comprising a first metal including silver, which is positioned to circumscribe a front surface of the emissive element; and a metallic holder for holding the non-emissive member. The holder is in one embodiment made of a copper alloy including a major portion of copper and a minor portion of another metal, such as nickel. After assembly, the electrode is subjected to a heat treatment that causes a thermal bonding between the relatively non-emissive member and the metallic holder, which, during subsequent operation of the electrode, provides good thermal conduction away from the emissive element and improves the consumable life of the electrode. Advantageously, during the heating step, the nickel attenuates the eutectic reaction between the copper and the silver that would otherwise occur and allows bonding over a wide range of temperatures and heating cycle durations. In addition, the temperature at which bonding occurs between the non-emissive member and the holder is also raised. As a result, if desired, a thermal bond can also be formed between the hafnium emissive element and the non-emissive member during the same heating cycle, thus further promoting thermal conductivity of the electrode. In alternative embodiments, other metals and other configurations, such as the use of an intervening plating, powder or sleeve are used to raise, and provide a greater range for, the temperatures over which bonding occurs between the non-emissive element and the holder.

Title: Histogram-based virus detection
Inventor: NACHENBERG CAREY S
IPC: G06F1/00
Filed: 2001-03-13
Abstract: A virus detection system (VDS) (400) uses a histogram to detect the presence of a computer virus in a computer file. The VDS (400) has a P-code data file (410) for holding P-code, a virus definition file (VDF) (412) for holding signatures of known viruses, and an engine (414) for controlling the VDS. The engine (414) contains a P-code interpreter (418) for interpreting the P-code, a scanning module (424) for scanning regions of the file (100) for the virus signatures in the VDF (412), and an emulating module (426) for emulating instructions in the file. The emulating module (426) contains a histogram generation module (HGM) (436) for generating a histogram of characteristics of instructions emulated by the emulating module (426) and a histogram definition module (HDF) (438) for specifying the characteristics to be included in the generated histogram. The emulating module (426) uses the generated histogram (500) to determine how many of the instructions of the computer file (100) to emulate. The emulating module (426) emulates (712) instructions and the HGM  (436) generates a histogram of the instructions until active instructions are not detected. When active instructions are not detected (714), a P-code module is executed (722) to analyze the histogram (500) and determine whether a file (100) contains a virus. The P-code can also decide to extend (728) emulation.  The HGM (436) is also used to detect (822) the presence of dummy loops during virus decryption.
