Abstract: An aluminum alloy fin stock material comprising about 0.9-1.2 wt. % Si, 0.3-0.5 wt. % Fe, 0.20-0.40 wt. % Cu, 1.0-1.5 wt. % Mn, 0-0.1% Mg and 0.0-3.0% Zn, with remainder Al and impurities at ?0.15 wt. %. The aluminum alloy fin stock material is produced in a form of a sheet by a process comprising the steps of direct chill casting an ingot, hot rolling the ingot after the direct chill casting, cold rolling the aluminum alloy to an intermediate thickness, inter-annealing the aluminum alloy cold rolled to an intermediate thickness at a temperature between 200 and 400° C., and cold rolling the material after inter-annealing to achieve % cold work (% CW) of 20 to 40%. The aluminum alloy fin stock material possesses an improved combination of one or more of pre- and/or post-brazes strength, conductivity, sag resistance and corrosion potential. It is useful for fabrication of heat exchanger fins.

Abstract: The present disclosure relates generally to a free-standing support system and, more particularly, to a portable and adjustable free-standing support system for supporting an umbrella or the like. The stand includes at least one pole, a holding clamp connected to the at least one pole, and a base connected to the at least one pole. The base includes a hub, a plurality of legs pivotally connected to the hub, adjustment handle mechanisms connected to each of the respective legs structured to selectively lock each of the plurality of legs at a fixed position with respect to the hub, and a plurality of adjustable feet. Each the adjustable feet are connected to a respective one of the plurality of legs and include a first end including a head and a second end including a spike, wherein each of the adjustable feet rotate between a first position which has the spike in a stowed position within each of the plurality of legs and a second position, wherein the spike extending from each of the plurality of legs.

Abstract: A simulated blasting cap includes a tube and an explosive simulant disposed within the tube. The explosive simulant includes one or more inert components and has a density substantially similar to an explosive material. The simulated blasting cap further includes a bridge wire disposed within the tube.

Abstract: Disclosed herein are embodiments of simulated explosive materials and Threat Screening Kits and simulated IED Circuit Kits including simulated explosive materials. The simulated explosive materials are configured to produce an output signal consistent with the presence of an actual explosive material when scanned in an X-ray scanner.

Abstract: A double-walled metal building is provided wherein the exterior walls snap into place. The exterior walls are formed of panels which have inturned lips at each side which fit into mating slots and the bottom is provided with clips to hold the bottom of the panel in place. The panel is secured by a top cap which covers the tops of both the interior and the exterior walls, locking the structure together. The only fastening elements which must be installed by workmen are self-tapping screws holding the top cap in place.
