Abstract: A cooler cabinet having a refrigeration system, and particularly devised to maintain articles to-be-cooled, such as milk cartons and the like, and permit the continuous entry into the cabinet enclosure for the removal of the articles is disclosed as having a main chamber for the articles, an upper, separated chamber for enclosing the evaporator for the refrigeration system and a lower, separated chamber for enclosing condenser and compressor. Air distribution fans are positioned in the upper chamber and are arranged to produce circulatory air movement across the evaporator to be cooled thereby in the upper chamber, then downwardly along the front wall of the main chamber then across the floor of the main chamber, then upwardly along the back wall of the chamber in an air return path and back to the vicinity of the evaporator for continued recirculation. Wire grates are positioned on the floor and the front wall along which air is moved downwardly.

Abstract: Coating compositions and pellets coated therewith which are adaptable for oral administration to ruminants are disclosed. The coating protects the core material of the pellets in the rumen and releases it postruminally. The coating is a specific mixture of a film-forming polymeric material, hydrophobic material and flake material.

Abstract: A post-rumen effective composition for oral administration to ruminants containing a bioactive substance molecularly dispersed with a basic polymer. The bioactive substance is miscible with the polymer and may be a vitamin, antibiotic, peptide or anti-inflammatory agent. The basic polymer contains from about 1 percent to about 25 percent by weight of nitrogen and is resistant to a pH of greater than about 5 and soluble or swellable at a pH of less than about 3.5.
