Abstract: An integral, monolithic mounting bracket supports a corner of a photovoltaic module. The bracket includes a ballast tray for holding one or more ballast blocks, and includes a plurality of monolithic support legs that are disposed at acute angles from a plane of the ballast tray and that are integral with the ballast tray. The bracket can be manufactured by stamping at least two identical sections of metal from the sheet and then bending-up each section on its remaining uncut fourth side into a near-vertical position, so that each bent-up section forms a monolithic support leg.

Abstract: A tubular body supports a fluid actuated tubular piston connected to operate a coupling mechanism for releasably securing the body to a valve or inlet fitting on a refrigerant or coolant receiving system. The body encloses components which define a center passage connected to the fitting for first evacuating air from the system and then for directing liquid refrigerant or coolant into the system. In one embodiment, the passage receives an elongated valve opening member which is fluid actuated to a position opening the valve fitting, and a movable valve member closes the passage to the flow of refrigerant. The fluid actuated coupling mechanism provides for convenient and simple insertion of the tool assembly onto the fitting with no insertion force and also for automatic release of the tool assembly from the fitting after charging is completed. A fluid actuated valve member minimizes the loss of coolant or the volume of residue refrigerant which vaporizes when the tool assembly is removed from the fitting.
