Abstract: The present invention is a compressed gas cylinder carrier for retaining and transporting a plurality of such cylinders. The carrier includes a cage or framework having a base and top interconnected by a plurality of vertical bars. The base includes slide rails on which is slideably mounted a sled that can move between opposite ends of the carrier within the framework thereof. The sled has a base and a sidewall portion integral there with and extending upward there from. The sled base and sidewall form a cylinder retaining space. One carrier end has a hinged door for providing access to the interior of the carrier. A strap extends around the sled and is engaged through an adjustable buckle secured to the door. The top end of the carrier has a roof structure for forming a forklift receiving cavity. In operation, the present invention is sized to retain a plurality of compressed gas cylinders.

Abstract: A plurality of individually adjustable flat mirrors on a common bed of a solar collector assembly reflect the sun's rays into a tubular collector where water is converted to steam for selectively either driving a motor of refrigeration system which cools a cool water tank or directly heating a hot water tank. Coils in the cool water tank supply coolant for room heat exchangers. The exhaust of the motor heats the hot water tank and is then recirculated to produce more steam. Coils in the hot water tank preheat tap water for a hot water heater and other coils therein supply heat for the room heat exchanger. The mirrors are in rows and are individually swivelly mounted and the frame of the collector assembly is pivotally mounted to track the sun. The collector assembly pivots about two divergent axes to track the sun and is counter balanced with respect to both axes.
