Abstract: A method for sharing digital content includes determining whether a first computing device is physically located within a defined geographical area, if the first computing device is physically located within the defined geographical area, providing access of shareable digital content to the first computing device, instantiating a tethering object associated with the shareable digital content, the tethering object including at least a first endpoint at the first computing device and a second endpoint at a second computing device remote from the first computing device, and providing access of at least a portion of the shareable digital content, via the tethering object, to the second endpoint at the second computing device remote from the first computing device. Other example methods and computer systems for implementing content sharing methods are also disclosed.

Abstract: A valve housing has three ports with butterfly valves mounted in two of the ports with stems coupled to the valve disks and extending through opposite sides of the housing. A linkage couples the valve stems together at one side of the housing, while an actuator is coupled to at least one of the valve stems on the opposite side of the housing. The linkage and control mechanism can be reversed such that valves can be mounted in an installation either as a left hand or a right hand valve.
