Abstract: A medical services unit for use in health care facilities where high security is required, such as in prison and psychiatric hospitals. The unit comprises a floor-to-ceiling column with an internal medical services section to provide a plurality of medical services. The medical services section is protected by a rotating steel door that prevents access to the enclosed services. The medical services section also includes a sub-door made of a transparent, shatterproof polymer, such as polycarbonate. Thus, the clear cover panel permits visual access to the gauges and controls for the services, but prevents unauthorized physical access to them. The column is entirely enclosed in a protective casing made out of rolled steel. Doors are provided in the casing for providing access b authorized personnel only to the internal medical services section.

Abstract: An artificial stone material having an improved natural stone appearance and texture is prepared from resin, curing agent, microspheres and additives. The resin, curing agent and microspheres are mixed to form a catalyzed base material. Additives are non-homogeneously worked into the catalyzed base material to provide a catalyzed stone mixture having a desired natural stone appearance. The catalyzed stone mixture is molded or applied to a surface at the point of use and allowed to cure to form the artificial stone material.

Abstract: Certain example embodiments relate to a storm shutter assembly clip used for stitching together multiple storm shutter panels in making a storm shutter system, and/or assembly method for accomplishing the same. The clip includes upper and lower portions, with the upper portion having at least one arm extending therefrom, and the lower portion having a housing including a nut. A hole is formed in the lower portion. The upper and lower portions of the clip may be angled so as to correspond with an angle formed by intermediate portions of the storm shutter panels. The at least one arm of the clip is slipped over an end of the first shutter panel so that the hole of the clip aligns with holes of the inner and outer shutter panels. A screw is fed through the holes of the first and second shutter panels and the clip so as to engage with the nut, the shutter panels tightening together via the screw being received by the nut in forming the storm shutter system.

Abstract: A skylight shaft substrate has a film or coating on its inside surface that reflects visible light while transmitting IR to the tube substrate, which can have a satin black and/or other IR absorbing interior and anodized or other high emissivity exterior to convey heat across the tube so that light is transmitted down the tube but heat transmission is directed through the tube to minimize heating the illuminated space. Or, heat may propagate up through the tube and exit through a clear plastic dome covering the tube.

Abstract: A new connecting node set that is unique and surprisingly effective at aligning interfacing holes in connecting nodes is illustrated by their application to radial tetrahedral structures. This method of connecting one node to another requires that a left handed node be connected to a right handed node. They are called left handed or right handed because their lines of interface in at least two directions of intended use are geometrically coincident with straight line rulings of a hyperboloid of revolution of one sheet which itself consists of two families of straight line rulings, designated a left handed and a right handed family respectively. With these nodes, magnets could be placed on the lines of interface (opposite placement in a left handed one from a right handed one) and thus the magnets would always attract or repel as preferred.

Abstract: A stringer assembly includes a support element, a plurality of brackets and a plurality of alignment elements. The brackets are connected to the support element, and each bracket includes a rise indicator corresponding to a desired rise dimension and a run indicator corresponding to a desired run dimension. The alignment elements align the rise or run indicator on one of the brackets with the other of the rise or run indicator on an adjacent one of the brackets to space the brackets at a desired rise and run. The brackets each include a tread flange and a riser flange, such that a tread and a riser can be directly connected to each bracket. The brackets may include cutouts for a temporary tread system.

Abstract: It is known to assist cooling of a combustion chamber in a gas turbine by fixing an exo-skeleton tile structure to an inner annular combustion liner shell. To improve structural integrity of the exo-skeleton tile structure, each tile is formed with at least one rib extending circumferentially across the outer surface of the tile. An end of each rib projects beyond one edge of the tile, like tiles being linked at overlapping edges by the inter-engagement of a projecting rib of one tile with the rib of an adjacent tile. The inter-engaging ends of the ribs are relatively slideable circumferentially to allow thermal expansion and contraction of the exo-skeleton structure, but sockets are provided where the ribs engage so as to resist relative bending of the adjacent tiles about their linked edges and impart rigidity to the structure.

Abstract: The invention includes a work platform and support system that includes a hub and joist configuration, wherein the hubs and joists are capable of articulation, or pivoting. One method of installation allows for sections of new work platform system to be extended from an existing suspended work platform system. The system is also capable of supporting, without failure, its own weight and at least four times the maximum intended load applied to it.

Abstract: A flexible, inflatable shelter is held within a storage container. The shelter can be erected rapidly, by directing compressed gas held or produced within the container, into the flexible material which will define the finished shelter. Personnel using the shelter then enter through an air lock door located in the storage container. An air lock may be alternatively provided such that is located at least partly within the deployed shelter, and so that it does not occupy substantial space in the container. The container includes supplies necessary to sustain life for an extended period. The shelter can be used to protect personnel from harmful environments caused by accidents or explosions in mines, tunnels, industrial plants, and the like. The container is compact, but allows rapid deployment of the flexible material to produce a shelter which is of approximately the same volume, or greater, than that of the storage container.
