Abstract: A dispenser is provided for liquids, the dispenser having a container and an outlet at a predetermined first level. The pressure in the container can be varied and a reservoir receives liquid from the outlet. A discharge passageway extends upwardly from the first level and terminates at a discharge opening at a second level, and an air relief opening is provided above the first level. The relief opening is no lower than the second level so that liquid displaced from the container flows into the reservoir and out of the passageway while air is trapped in the reservoir above the first level. Consequently any gradual increase in temperature will cause air from the reservoir to be displaced through the air relief opening to minimize the risk of temperature driven dispensing. The passageway is defined by the combination of a cup-shaped base and a sleeve within the base.

Abstract: A separator is fed with liquid from a slaughterhouse which will be a mixture of water, tallow, and solids. The tallow rises to the top, and solids go to the bottom. Nearly clean water is withdrawn between the top and bottom. The nearly clean water is withdrawn into a plenum ring which is blocked at one point and has an outlet pipe connected adjacent to the block. Therefore, the liquid in the plenum ring flows in only one direction. The cross section of the plenum ring is many times greater than the cross section of the outlet pipe so that the flow within the plenum ring is gentle.

A sump in the plenum ring adjacent to the outlet pipe draws off any solid which settle out in the plenum ring. A constant bleed is provided at the bottom of the sump to help withdraw the settling solids.
