A process for increasing the softening point of asphalt using an eductor, preheated asphalt is mixed with an input gas in the eductor to form a gas/asphalt mixture. The gas/asphalt mixture is conducted to a heated and pressurized oxidizer vessel via piping connected to the discharge connection of the eductor, where the piping enables a bubble flow pattern to develop therein to enable reaction of the oxygen with the asphalt. The oxygen entrained asphalt mixture is discharged from an exit port of the piping in the oxidizer vessel. The resulting oxidized asphalt product stream has a softening temperature greater than the preheated asphalt feed. The process minimizes the off-gas produced to reduce the carbon footprint.

An electrically heated hair roller includes a roller body defining an exterior curling surface and a hair clamp pivotally mounted to the roller body and movable toward and away therefrom between in open position allowing hair to be wound on the body and a closed position clamping wound hair against the curling surface. An electric heater within the roller body heats the curling surface and is powered by a battery contained within a compartment formed in the clamp. Cooperative separable electrical plug and jack elements on the clamp and roller body electrically interconnect the battery to the electric heater. The connector elements also operate as a mechanical fastener for securing the clamp in the closed position. The arrangement is such that the electrical interconnection is interrupted upon release of the clamp from its closed position. The battery may be rechargeable and a combination battery charger-storage rack may be provided for holding the curler and recharging the battery without need to remove the battery from the battery compartment.
