Abstract: An Apparatus for applying cushion gum to a periphery of a tire casing without cement includes a conveyor having a forward roller near the tire casing. The conveyor is mounted on a carriage that is movable relative to its base so that the conveyor can be moved to contact the tire casing. The conveyor moves the cushion gum below an infrared heater to heat an interface side of the cushion gum to increase its tack and then moves the heated cushion gum between the forward roller and the tire casing. The forward roller of the conveyor applies the cushion gum to the periphery of the tire as the cushion gum exits the conveyor and first contacts the tire casing. A supply roller is provided to move the cushion gum from a supply roll to the rear end of the conveyor. A cutting mechanism is provided between the supply roller and the conveyor to selectively cut the cushion gum.

Abstract: An improved method for removing sodium salts from mixtures of such salts and polyaryloxyphosphazene or polyalkoxyphosphazene or polyalkoxyaryloxyphosphazene polymer solutions is provided. The method involves first treating the mixture with an acid to neutralize any excess alkoxide or aryloxide. Then, water is added to the mixture to extract the sodium salts therefrom resulting in an at least partial separation of the mixture into a polyphosphazene polymer solution phase and a brine phase comprising water and the sodium salts. Following addition of the water to the mixture, a sulfated fatty acid ester of a natural non-petroleum based oil is added to the mixture to effect a more complete separation of the mixture into the polyphosphazene polymer solution phase and the brine phase. The polyphosphazene polymer solution phase is then separated from the brine phase.
