Abstract: A shelving unit including three wall clip/brackets and a shelf pivotally attached to the clip/brackets. Each clip/bracket includes a mounting engagement portion and a pair of parallel, extending arms. Each arm has a curved slot, and a pivot hole positioned above one end of the slot. The arc of the slot sets the other end of the slot higher. The shelf is pivotally bolted to the clip/bracket. A pin pivotally passes through the curved slots of the pair of arms and engages the shelf. One of the three clip/brackets has an additional vertical retention slot at the lower end of the curved slot. The shelf is pivotable to a first, substantially horizontal position with the pins at the other end of the slots, and to a second, substantially vertical position with the pin of the one of the three brackets being in the vertical retention slot of the one bracket.

Abstract: A tactical power adaptor is provided which adapts power from worldwide power sources and supplies the power to a plurality of electronic devices. A power input provides uninterruptable power to the adaptor to ensure that the input power does not interrupt the electronic device if the source is interrupted. A converter converts the input power from the worldwide sources to a power manageable by the adaptor. A plurality of connectors each supply a different variable voltage. A voltage varying circuit allows an operator to vary a voltage of the connectors and a channel selector selects between the connectors. Power switching modules supply the correct amount of power to a corresponding connector according to the voltage set by said voltage varying circuit.

Abstract: The mobile water chiller apparatus of the present invention comprises a refrigeration system, a water system and an engine for driving the water and refrigeration systems. The water system includes a thermostatically controlled blending valve to temper warm water from the water supply with cool water from the evaporator heat exchanger of the refrigeration system so as to provide a constant load to the evaporator heat exchanger inlet and an immediate source of cool water.
