A display system is easily attached to the safety bar of a chair on a chair lift system at the beginning of a season. The display system includes brackets formed of rails holding clamp portions that may be fastened together to clamp the display system to a chair, such as to the safety bar across the lap of a rider. At the end of a season, the display system may be removed from each chair, the clamp portions removed, and the display systems stacked. In one simplified system, adjacent displays may be stacked back to back, and such adjacent pairs may be stacked with the displays in adjacent pairs positioned face-to-face. Thus, metal brackets on the backs need not scratch up the reading faces or surfaces. Meanwhile, the displays may be stored in minimal space, with great stability, while minimizing wear and damage.

A general purpose support system adaptable to a ski rack, bicycle rack, barricade, bench, table, advertising display, or the like, is formed of two tubular members, typically of steel tubing each bent in a single piece to form a leg portion at each end with an intermediate transverse portion therebetween. In service, at least one transverse portion may extend between the tops of the two respective leg portions. Each leg portion is attached to the opposite legs of the other tubular member. Two transverse members may be spaced apart from one another to form a yoke for carrying and to increase the capacity of the support for bicycles, skis and the like. The racks may be stackable for storage, and light enough to be moved to an inside storage location daily. Each leg portion is bent to form a knee portion located proximate the top thereof and near the transverse portion. The two tubular members may be anchored separately or may be joined at each end to be free-standing.

A ski security system includes a moveable rack for supporting pairs of skis when not it use. The rack is formed of two tubular members of galvanized steel tubing each bent in a single piece to form a leg portion at each end with an intermediate transverse portion therebetween. In service, each transverse portion extends between the tops of the two respective leg portions, which are themselves attached to the opposite two legs of the other tubular member. The transverse members are spaced apart from one another to form a yoke for carrying. The racks are stackable for storage, and light enough to be moved to an inside storage location daily. Each leg portion is bent to form a knee portion located proximate the top thereof and near the transverse portion. The two tubular members are joined at each end, being connected at the respective knee portion of each, the legs extending away therefrom upward and downward as well as outward. The transverse portion of each tubular member is provided with a continuous filament formed into alternating slots and loops.

A system and adjustable apparatus for applying COgas to improve Cannabis production. The system includes upstream and downstream stages or subsystems. The upstream subsystem receives and stores gas, particularly CO2 gas. It monitors the environment of the downstream subsystem, determines when and how to apply gas to plants growing in the downstream system, acquires gas stored in the upstream subsystem, and distributes it to the downstream system. It also has various monitoring, command and control, management, and reporting features. The downstream subsystem includes one or more plant growth areas or plots, gas distribution means, such as gas conduits, tubes or lines from the midstream subsystem, and the high efficiency, adjustable gas applicator, and various sensing and monitoring devices communicatively connected to the upstream subsystem. Also disclosed are odor mitigation and humidity control features.
