Abstract: A barium carboxylate-based heat stabilizer for CPVC compounds and the CPVC compounds containing these stabilizers is disclosed. The compounds containing these stabilizers exhibited extended decomposition time, enabled lower torques for the case of processing and increased their impact resistance.

Abstract: A thermal oxidizer including an oxidation mixer, an oxidation chamber, and a retention chamber forming a fluid flow path for thermal oxidation of a waste gas. The thermal oxidizer also includes first and second electric heating elements. In operation, the first and second electric heating elements pre-heat portions of the thermal oxidizer. Once a threshold temperature has been reached, the oxidation mixer facilitates a combustible mixture of the waste gas and an oxidant into an combustible waste gas stream, the oxidation chamber facilitates a primary combustion reaction of the combustible waste gas stream into an oxygenated waste gas stream, the retention chamber facilitates a secondary combustion reaction of the oxygenated waste gas stream into oxidized gases and the heat dissipator reduces the temperature of the flow of oxidized gases within the heat dissipator.

Abstract: In one aspect, a method is provided for controlling access to a facility including a movable barrier and a plurality of loading docks. The method includes receiving, from a user device associated with a vehicle, a check-in communication that includes a check-in identifier. The method includes receiving a verification communication that verifies a presence of the vehicle relative to a sensor associated with the movable barrier. The method further includes causing a movable barrier operator associated with the movable barrier to move the movable barrier between closed and open positions in response to the check-in identifier indicating authorization to access the facility and in response to receiving the verification communication. Further, the method includes selecting a particular loading dock from the plurality of loading docks and communicating a loading dock identification representative of the particular loading dock to the user device to direct the vehicle to the particular loading dock.
