Abstract: A tangle-free flag or banner that incorporates anti-fall back feature[s] that incorporates a weighted and flexible fly hem that is integrally built into the flag/banner that acts as a stabilizing keel. This design implementation provides much greater self-righting capabilities and prevents tangling and furling by taking advantage of the external forces of gravity in concert with the nature of the lift created by the wind and its attendant forces.

Abstract: An oil filter cartridge for internal combustion engines that employ oil filters in their operation. The input side of the cartridge is filled with microscopic solid lubricating particles of polytetrafluoroethyline (PTFE) dispersed in an oil carrier base. The microscopic particles of PTFE are of varying sizes, with the finest below the minimum given size of the filter and pass immediately into the oil circulating system. The larger sizes are gradually broken down by the high temperature, pressure and swirling flow within the filter cartridge so as to gradually pass through the filter to provide enhanced lubrication by the circulating oil during the operating life of the oil filter cartridge.

Abstract: A filter for the engine oil systems of internal combustion engines, fits into a standard oil filter cartridge or recepticle. The filter cartidge may be of any conventional type, but should be of the best quality, and able to remove as much as possible of the particulate contaminents to provide the best possible mechanical filtering function. The body of this filter cartridge is impregnated with specific chemicals of the type normally added to the lubricating oils by the manufacturer before distribution to counteract the inevitable oxidation, nitration and changes in acidity that degrade a lubricating oil in normal use. The chemicals must be impregnated into the filter in such a manner as to leach into the crankcase oil, over a period of time, in amounts that will compensate for losses in the system, and the amounts and types of chemicals can be structured for any given car, for a given mileage, and for given driving conditions.
