A trap chamber is formed by a cylindrical container and a head sealed to and closing the upper end of the container, which is releasable from the head by actuating a detent. Air and entrained liquid from a milk receiver are sucked into the head through a tangential inlet from which air discharges through a top outlet to a vacuum pump while separated liquid spirals down along the chamber wall to a valved drain outlet. Liquid accumulating in the chamber eventually raises a floating ball valve against a seat to close the air outlet and break the vacuum so that the chamber is drained through the bottom outlet. The ball valve is then released from its seat by an element operable to break the vacuum in the air outlet. Vacuum in the chamber draws the container upward to compress a sealing gasket against the head and thus prevent leakage.

Universal sanitary trap

An animal feeding station having an improved design to facilitate feeding of the animal. In particular, a manger that has a bottom portion approximating a hemispherical shape, side wall portions extending upward from the bottom portion as a conical tangent of the hemisphere, a front wall portion which extends vertically upward and is tangential to the aforesaid hemispherical portion and a rearwardly, upwardly sloped flat surface portion which generally conforms to the position of the animal's lower jaw when ingesting its food. Further, a shroud is provided over the manger which has a top wall sloped and disposed in a manner which restricts the vertical movement of the animal's head until the animal moves rearwardly. Another feature of the stall is the provision of slidably removable side panels, which permit the animal to eat in relative isolation and without the eye distraction caused by being able to see animals outside the stall. Further, a bar shaped in the form of an arch extends over the rear portion of the animal so as to preclude mounting of the feeding animal by stable mates. For use with electronic automatic feed control systems, there is provided a front panel through which the animal extends it head, which houses an encapsulated antenna having a metal reflector.
