Title: Method for The Production of Bare (Non- Functionalized) Multiple-Element Magnetic Nanoparticles and Their Use in Fast Detection and Removal of Pathogenic Bacteria from Water Resources.
Inventor: D KHALED NAJEEB ABD AL-QADER AL SHREDAH
Filed: 2008-02-28
Granted: 2008-10-09
Abstract: The invention provides cheap, and a non-water consuming physical method for the production of Multiple-element Magnetic Nanoparticles (MMN), from fly ash collected from chimneys of iron and steel factories in Jordan, and the use of these MMN for the fast detection and efficient removal of bacterial pathogens from contaminated water resources. Wet sieving of fly ash was performed, magnetic particles separated using a magnet and mixed with sodium chloride salt to provide for a good dispersion and harvested by a magnet while attached dust was blown away using a small air pump, and nanoparticles obtained using a centrifuge. Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM) and Atomic Absorption revealed sizes of MMN of <100 nm and main chemical components of iron and Zinc. Small amounts of Bare MMN (4-6 mg/ml) without any surface modifications were used for fast detection and removal of bacterial pathogens from naturally contaminated water resources such as wastewater and grey water. Bacterial pathogens were drastically reduced by a factor of 103-104 for wastewater, and 102-103 for grey water using a magnet after aggregating with MMN (some MMN penetrated inside bacterial cells as viewed under TEM). The MMN had no effect on bacterial growth and viability

Title: Method for damping the pressune oscillation in ehaust gas flow
Inventor: CURTIL R
IPC: F02B37/00

Granted: 1982-05-17
Abstract: Pressure oscillations in exhaust manifold(6) of multicylinder I.C. engine are smoothed out by opening the exhaust valves as the associated pistons approach bottom dead center. The flow of exhaust gas from the cylinders is throlled by reducing the cross-section of the flow area by a factor between 0.3 & 0.8 in a connecting pipe (8) between the valves & the manifold. The gas flow is accelerated as it passes from the pipes to the manifold by restricting the cross-sectional flow area in the manifold to a valve lower than the bore area of the cylinders.
