Abstract: A system enables universal remote media control across multiple platforms, devices, and users. A protocol allows a cast controller to have access to media operations and a state(s) associated with media content. The system receives commands from a cast controller, provides the commands to a media player, loads new media content into the media player, based on the commands, and receives state notifications from the media player. Another cast controller can receive the state notifications from the media player and control the media player based on the media operations and state(s) associated with media content.

Abstract: Prior to carrying out a gaseous phase chemical reaction, a liquid phase organic compound which is prone to degrade is vaporised at elevated pressures with the aid of a second compound. In one embodiment of the invention, vaporisation is effected by co-vaporising a mixture of the two compounds in a vaporiser. In another embodiment, the first compound is injected into a hot gaseous stream and undergoes atomisation into droplets which then vaporise within the gaseous stream. The second compound is used to assist the atomisation process and/or to sweep atomised droplets of the first compound away from hot surfaces where the first compound would otherwise tend to undergo degradation if the droplets are allowed to reside in contact with such surfaces.

Abstract: Prior to carrying out a gaseous phase chemical reaction, a liquid phase organic compound which is prone to degrade is vaporized at elevated pressures with the aid of a second compound which together with the organic compound produces a mixture having a boiling point less than that of the organic compound. In one embodiment of the invention, vaporization is effected by co-vaporizing a mixture of the two compounds in a vaporiser. In another embodiment, the first compound is injected into a hot gaseous stream and undergoes atomization into droplets which then vaporize within the gaseous stream. The second compound is used to assist the atomization process and/or to sweep atomized droplets of the first compound away from hot surfaces where the first compound would otherwise tend to undergo degradation if the droplets are allowed to reside in contact with such surfaces.
