Abstract: A filter turning mechanism is attached to an engine in proximity to a filter (such as an oil filter), and may be used to install or remove a filter by turning the filter. The filter turning mechanism contacts a filter, and rotates the filter when the filter turning mechanism is rotated with a tool. One implementation of the filter turning mechanism includes an inner drive gear and a filter drive mechanism. The inner drive gear normally spins freely within the filter drive mechanism, but when pushed into the filter drive mechanism with a suitable tool such as a ratchet extension, the inner drive gear engages the filter drive mechanism, thereby causing rotation of the inner drive gear to rotate the filter drive mechanism as well, which in turn rotates the filter.

Abstract: An improved process and for removing NOx from exhaust gases produced by combustion-based energy sources. Catalyst-free exhaust gas is directed into one or more ducts. The gas is cooled and then passes through the duct, wherein the gas flow rate and the electron beam pulse rate are configured to cause each successive volume of gas that flows past the window to be subjected to only a single electron beam pulse in the reaction chamber. A single short, intense electron beam is fired into the exhaust through a window in the reaction chamber as the exhaust flows past the window, with some of the electrons being reflected back into the gas by a reflective plate situated opposite the window. The deposited electron energy causes NOx from the exhaust to be converted into N2 and O2 which are output into the atmosphere with the thus-scrubbed exhaust.
