  • Patent number: 11932521
    Abstract: A system and method for quickly and efficiently installing a toilet using a hoist. The toilet hoist includes a hoist base, at least one leg, a drive system, a power system, and at least one support mechanism. The at least one leg is coupled to the hoist base. The power system controls actuation of the drive system; when actuated, the drive system alters the vertical position of the support mechanism. The support mechanism is configured to secure a toilet for hoisting.

  • Patent number: 10302382
    Abstract: A system and method for quickly and safely inserting multiple rounds of ammunition into a magazine. The system is adjustable for various sizes of magazines and calibers of cartridges. Users depress a plunger that applies a force to the exposed cartridge in the magazine thereby compressing the spring inside the magazine and providing room for another round to be inserted into the magazine. The plunger is then released and the process can be repeated until the magazine is filled or the user is done.

  • Patent number: 10131560
    Abstract: A system and method includes an aeration subsystem that excites enzymes in the liquid waste passing through the septic system along with a bypass system that directs liquid waste during power outages. The bypass system utilizes a mechanically activated bypass valve moved by a float. The aeration subsystem includes a compressor section that compresses the liquid waste. The method includes mixing enzymes into the fluid waste material, compressing the fluid waste material with the compressor, injecting air into the compressed fluid waste material, and determining whether the fluid waste material is at a desired cleanliness, and if not, recirculating the fluid waste material through the compressor.
