  • Patent number: 6550182
    Abstract: Disclosed is an implantable aerating root pruner (IARP) formed from a pair of thin walled substantially identical rigid sheet members which are dismountably fitted together to form a stake-like conduit each of which sheet members has a plurality of apertures therein which creates a grate-like structure with a high ratio of total open area to total surface area, one end of each of which is tapered to form, when the sheet members are fitted together to form the IARP, an edge or point which facilitates insertion of the IARP into planting medium and the end portion of the other end of each thereof lacks the apertures and is adapted to project above the surface of the planting medium. The sheet members can be flat separate elements which form a box-like conduit or semi-cylindrical and joined together by hinges and which form a cylindrical conduit.

  • Patent number: 5918415
    Abstract: A multi-purpose automatic filing basin is provided for containing a selected amount of water which is used for various purposes. The water may be transferred from the basin by wicks or by a pump to water using devices such as plant pots or toys or may be provided for direct use from the basin for devices such as animal feeders and habitats. The basin is kept supplied with water from a pressurized source by a specialized valve which opens in response to a drop in water level below a first selected level and closes in response to the water level reaching as second selected level.
