Abstract: Polymer compositions for making a stabilized polymeric articles that are resistant to discoloration upon exposure to UV-C light having: (i) an organic polymeric material; and (ii) a hindered phenol, organic phosphite, or a combination thereof, with the provisos that: (a) the OH group on the aromatic ring of the hindered phenol is flanked by two tertiary hydrocarbyl groups, and (b) the organic phosphite does not have any-OAr group linked directly to the P atom of the phosphite, wherein Ar represents an unsubstituted or substituted aryl group, are provided herein. Reduced discoloration is associated with the use of specific hindered phenols and the organic phosphites compared to other hindered phenols and organic phosphites, even in the absence of other polymer additives including UV absorbers, hindered amine light stabilizers (HALS), metal oxides and/or barium salts. Methods of reducing discoloration of an organic polymeric material upon exposure to UV-C light are also provided, wherein such methods include the step of adding to the organic polymeric material a stabilizing amount of hindered phenol, organic phosphite, or a combination thereof.

Abstract: A receiver for irregularly shaped bricks cast from non-volatile bituminous material includes a receiver with a specialized storage chamber that can receive viscous bituminous material and a concave lid preferably modified with a radiant heating system that can accept and melt or soften arriving bricks. The lid includes multiple openings or other delivery routes that funnel the melted bituminous material to the chamber below. The radiant heating system can be electrical where cables or grids are embedded in the lid or where conductive materials coat or are distributed throughout the lid. Alternatively, the radiant heating system can be hydronic where channels or conduits are embedded in the lid to circulate heated liquid such as water or water mixed with propylene glycol. The receiver can also include blenders, skimmers, and additional heaters to further skim, blend, or process the bituminous material collected in the chamber.
