  • Patent number: 11795679
    Abstract: A wastewater leaching chamber having asymmetric corrugations running transversely along the length of the chamber, where each transverse corrugation has a wide section on one side and a narrow section on the opposed side of the chamber, such that the corrugation walls run at an angle to the longitudinal axis of the chamber. The widest corrugation side of the chamber has a large straight sidewall, and the corrugation forms an arch which curve across and downward from the top of the straight sidewall to the narrow side of the corrugation at the opposing base of the chamber. The asymmetric arch is comprised of a multi radius curve from the top of the straight side to the opposing base footer.

  • Publication number: 20230257986
    Abstract: An overlapping joint coupling system for septic chambers where the end of one chamber is designed to fit over the opposite end of an adjoining chamber of like construction, and where the overlapping end coupling section includes a retention pocket for receiving a flexible snap locking member formed in the underlying end coupling section, and the connection of the end coupling sections forms a joint which enables one chamber to pivot in a horizontal plane relative the other chamber of like construction.

  • Publication number: 20210015057
    Abstract: An aeroponic basket system and method of use in is disclosed herein. The aeroponic basket system for use in aeroponic plant growth includes a germination basket having a basket area including at least four sidewalls defining at least four openings, and a base portion, coupled to the at least four sidewalls, the base defining at least one opening, the germination basket comprising compostable material. The germination basket further having an interface lip extending around a periphery of the basket area opposite the base portion, the interface lip configured to interface with an aeroponic plant growth surface, the interface lip comprising a u-shaped channel that extends around a periphery of the basket area, the u-shaped channel oriented toward the base portion. The aeroponic basket system for use in aeroponic plant growth includes an organic germination media configured to be housed within the basket area.

  • Patent number: 9469071
    Abstract: A fused filament fabrication system and method comprises a motor for moving the system along a linear rail during operation, a drive gear coupled to the motor. The drive gear rotates in the direction of the motor during operation and selectively operatively engages first or second idler gears during operation of the system. The system also comprises first and second filaments for the selective passage of material to corresponding first and second extruders, the first filament is positioned between the first idler gear shaft and idler bearing and the second filament is positioned between the second idler gear shaft and idler bearing.
