Abstract: Various embodiments enable a web browser to promote the availability of an installable application that is associated with a website to which the web browser has been navigated. The web browser is configured to discover the availability of these applications and, responsively, provide a user experience through which the user can acquire and install such applications, as well as switch to applications that have previously been installed. Thus, through the various embodiments, a user is relieved of the burden of having to navigate to a particular application store and periodically search for applications associated with sites to which they browse.

Abstract: A driving device for a vortex mixing apparatus comprises holders for holding a mixing unit of a type having at each opposite end a pumping diaphragm for imposing a pulsatile flow on a liquid passing through a primary channel in the unit. Two pistons are each arranged to cooperate with a respective one of the diaphragms and to reciprocate between a retracted position clear of the unit and an extended position in which it extends into a housing of the unit and compresses the respective diaphragm. Driving mechanisms are normally arranged to reciprocate the pistons in phase at the same frequency such that when one piston is moving from its retracted position to its extended position the other is moving from its extended position to its retracted position and vice versa. Control mechanisms are arranged, upon stopping of the driving mechanisms, to cause both pistons to adopt retracted positions so that the unit may be inserted into, and removed from the holders without interference from the pistons.
