Abstract: The invention is directed to improved systems, methods, and media for sharing digital content through social media. More particularly, the invention provides for sharing digital content using fragments. In some embodiments, two users share digital content with one other, where each digital content being shared is obscured and overlaid by fragments. Each user will take a turn to select a fragment to be revealed from the digital content being shared, and both users continue revealing fragments until all fragments are revealed. The revealed digital content can be further updated from an obscured format to an unobscured format. The revealed digital content can be available for both users to view for a predetermined period before it is deleted or recalled.

Abstract: In a flow meter of the type comprising a rotor consisting of a spindle 12 and bearing heads 9 and 11 cooperating with seats 5 and 6 to give support of the rotor, it has been found that the flow does not split evenly between the ends. In order to improve the flow performance, the flow characteristics of the two heads 9 and 11 are chosen to be different so as to have their transitions from laminar to turbulent flow occuring sequentially. It is preferred that the turbine means on the rotor be formed by angled passages through the bearing heads 9 and 11.
