Abstract: A magnetic power generating machine, including a central magnet, which is configured to traverse a path having first and second ends, and is connected by a linkage to rotate a shaft as the central magnet traverses the path, first and second side magnets, which are respectively disposed adjacent to the first and second ends of the path and are oriented to repel the central magnet, so that a magnetic force between the central magnet and the first and second side magnets causes the central magnet to oscillate between the ends of the path, thereby rotating the shaft and first and second shutter assemblies, each including at least one ferromagnetic shutter and a mechanism which is arranged to open the at least one ferromagnetic shutter as the central magnet approaches the shutter assembly, thereby modulating the magnetic force synchronously with oscillation of the central magnet.

Abstract: A toilet cleaning system, using a bifurcated communicating pipe which provides cleansing material to a toilet bowl. The system is provided as a component of a water closet, which is inexpensive to manufacture, and is capable of delivering a limited amount of cleanser to the toilet, while preventing accidental flushing of the cleanser unit into the toilet bowl. The bifurcated communicating pipe has an angled branch and allows a portion of the cleanser unit seated in the angled branch to project into the central channel of the communicating pipe for contacting the flush water, to provide cleansing action. The flush water passing through the communicating pipe dissolves or disperses a certain amount of the cleanser and therefore provides cleansing of the flush water. Optionally, a removable cap is present for sealing the angled branch, to prevent the flush water from exiting the angled branch. Anchoring means are provided for anchoring a cleanser unit within the angled branch.
