Abstract: A modular aeroponic growing column has an elongated first body, a fluid receiving cap, a fluid draining base cap, and a plurality of growing receptacles. The elongated first body includes a fluid receiving end, an opposite fluid draining end, an interior receiving space extending between the fluid receiving end and the fluid draining end, and a plurality of growing receptacle receiving openings positioned on the first body. The plurality of growing receptacles is positioned in the growing receptacle receiving openings.

Abstract: An artificial shingle adapted for mounting on substantially any roof surface (e.g., spaced slat- or solid sheathing-type construction) whereupon conventional shingles might alternatively be mounted, wherein the artificial shingle provides superior cost, wear, fire resistance, weight, or other characteristics while presenting a substantially realistic appearance and resemblance to a natural material (e.g., slate, cedar). The artificial shingle comprises a top surface and a bottom surface. A lower top exposure portion of the top surface and an upper bottom exposure portion of the bottom surface are both provided (e.g., stamped, molded, imprinted) with a relief or three-dimensional pattern substantially resembling the natural material of which conventional shingles are constructed. Other features include a midline groove with a cuttable end tab, and a portion of reduced thickness with strengthening corrugations.

Abstract: A bearing-like device using magnetic force to both passively facilitate and actively aid or enhance a turning, spinning, or other movement of an attached shaft or other member. In a preferred embodiment, the device comprises a conical male component spirally wrapped in magnetic material outwardly presenting a magnetic pole of a particular orientation and received within a correspondingly shaped female component including magnetic material outwardly presenting a magnetic pole having the same particular orientation, such that the male component is both magnetically repelled from the female component and magnetically induced to turn or spin relative to the female component.
