Abstract: A plant pot hanger has three or more cables, each of which cables have a first end and a second end, and wherein the three or more cables are secured together at the first ends of the respective cables. A sliding loop is formed at the second end of each respective cable. Each cable is threaded through the sliding loop of a respective adjacent cable to form a ring adaptable for running under a rim of a plant pot and supporting the plant pot. A loop or a hook for hanging the plant pot preferably extends from the respective first ends of the three or more cables.

Abstract: Disclosed herein is a method comprising imaging a network section through which flow occurs; where the flow is selected from a group consisting of fluid, electrons, protons, neutrons and holes; partitioning the image into sub-regions based on metabolic need and function; where each region comprises one or more sources and one or more sinks; where the flow emanates from the source and exits into the sinks; performing a Delaunay triangulation tessellation on one or more sub-regions by connecting one or more sources and one or more sinks; where the Delaunay triangulations maximize the minimum angle of all the angles of the triangles in the triangulation; generating a Voronoi diagram from the Delaunay triangulation by subdividing the sub-regions into Voronoi cells, where each Voronoi cell contains exactly one sink or one source; and where the intersections of Voronoi cells are Voronoi cell vertices; locating a sink endpoint centroid; connecting a source to a nearest Voronoi cell vertex; connecting at least one si

Abstract: Disclosed herein is a system and a method for analyzing apparent random pathways, patterns, networks, or a series of events and characterizing these apparent random pathways, patterns, networks, or a series of events by constructal analysis. The resulting statistical values obtained can be used to compare the apparent random pathways, patterns, networks, or a series of events with other apparent random pathways, patterns, networks, or a series of events. The comparison can yield knowledge about the apparent random pathways, patterns, networks, or a series of events as well as the neighborhood or surroundings of the apparent random pathways, patterns, networks, or a series of events.

Abstract: Methods are presented for controlling warpage during heat treatment of a 3DPBJ article having a cavity extending inwardly from an outside surface wherein a 3DPBJ article is 3DPBJ printed from a build powder as is a 3DPBJ object which is adap ted to be contactingly insertable into the cavity of the 3DP BJ article. At least a portion of the 3DPBJ article cavity surface and/or at least a portion of the surface of the 3DPBJ object is treated to prevent the 3DPBJ object from becoming bonded to the 3DPBJ article during the heat treatment. The 3DPBJ object is inserted into the 3DPBJ article cavity and the 3DPBJ article and the 3DPBJ object are heat treated to transform the 3DPBJ article into the intended article itself and the 3DPBJ object into a heat treated 3DPBJ object. The heat treated 3DPBJ object is removed from the article.

Abstract: Disclosed herein is a method for designing an organ for use in a body of a living being comprising identifying a fluid transport demand of an organ; where the fluid transport demand is the amount of fluid used by the organ to sustain itself and to sustain utility in other organs around it; and where the organ comprises a flow system comprising a network of vessels; determining a spatial density of zones of need in the organ based on a density of normal healthy tissues in the organ; identifying a nature of the flow system; and using constructal principle analysis to generate a design of the organ. Disclosed herein too is an organ manufactured by the aforementioned method.

Abstract: Petroleum coking drums and other vessels may be inspected to determine if dimensional changes or bulges have occurred in the surface of the vessel by an inspection device including a reflected laser light measuring survey apparatus and a video camera mounted on a frame which may be disposed in selected vertical positions along a central axis of the vessel and rotatably positioned by a rotary positioner interposed between a support stem for the device and the frame. Plural distance measurements and video scans are transmitted to a remote control console for recording and plotting of the contours of bulges or other dimensional anomalies surveyed by the survey apparatus. Components of the device are sealed or gas pressurized to minimize the chance of explosion in hazardous environments such as the interior of a petroleum coking drum. The system is adapted to be supported on the distal end of a coking drum drillstem and centralized by a removable clamp unit mounted on the drum manway flange.

Abstract: The transition interconnects microstrip transmission lines whose finite-width conductors are formed on the upper surface and whose ground planes are formed on the under surface of a ceramic substrate. A patternable metallizable multilayer thick film dielectric is applied to the under surface of the ceramic substrate. The transition comprises first and second vias which penetrate the ceramic substrate inside and outside a hermetic enclosure. The upper ends of the vias are connected to the finite-width transmission line conductors, and the lower ends of the vias are interconnected by a finite-width conductor formed on the under surface of the substrate. The lower conductor then forms a transmission line of either a microstrip or coplanar nature with a ground plane available on the underside of the assembly. The thick film dielectric facilitates sealing, and attachment of a metal base plate. All steps are performed using thick film processing.
