Abstract: A closure system of the present invention preferably includes a flexible or rigid container having container mating surface, a stiffening ring having a first ring mating surface and a second ring mating surface, and a stopper having a stopper mating surface. The first ring mating surface is matable to the container mating surface and the second ring mating surface is matable to the stopper mating surface. In one preferred embodiment a dosing cavity is defined in the stopper mating surface. The container may be sealed to have inhalation energy stored therein. When the inhalation energy is released, dosing material within the dosing cavity is inhaled into the container. The inhalation energy is stored as inhalation means such as vacuum or the deflection of at least one panel of the container or the closure system.

Abstract: By means of a novel triple-beam spectrophotometer, the protein and fat contents in milk can be simultaneously and rapidly determined. The system is self-compensating for discrepancies in the light path and for variations in lamp intensity, thereby yielding highly accurate analysis.

Abstract: Animal carcasses are thoroughly cleaned by a single pass through a cleaning unit having a pair of oscillating spray bar assemblies, each equipped with a plurality of nozzles arranged to collectively contact all exposed surfaces of the carcass. The cleaning unit is enclosed within an open-ended chamber having at either end a vestibular system of baffles for containing the spray liquid while permitting uninhibited passage of the carcasses.
