  • Patent number: 11835079
    Abstract: A bolt has an axis and a bolt plane perpendicular to the axis. The bolt has male bolt threads. Each male bolt thread has a bolt root and a bolt crest. Each male bolt thread forms axially interior and exterior male surfaces extending radially exteriorly away from the axis and forms a first angle with respect to the bolt plane. A nut has an axis and a nut plane perpendicular to the axis. The nut has female nut threads. Each female nut thread has a nut root and a nut crest. Each female nut thread forms axially interior and exterior female surfaces extending radially interiorly toward the axis and forms a second angle with respect to the nut plane.

  • Patent number: 5644801
    Abstract: A toilet system for reducing or eliminating the splash and noise normally associated with human waste as it falls and penetrates the surface of the water contained in a toilet bowl (10). This system includes a floating object or deflector (20) positioned at the surface of the water which functions to deflect the fall of the waste matter. An electrical circuit (1-6) generates an electromagnetic field, which interacts with the magnetic influenceable material of the deflector and/or a permanent magnet connected to the floating deflector. Interaction between the electromagnetic field and the magnetic influenceable material (e.g. iron) or permanent magnet allows the floating object to be maintained at a pre-determined, centralized and depth position on the surface of the water.
