Abstract: In order to make possible, with a valve having a sleeve (110) provided with a valve seat (112) and with a valve activating tube (118) which supports a spring-biased valve body (114) which can be tipped away from the valve seat (112), a high water flow rate even under low water pressure, it is proposed, instead of a support of the valve body (114) on the valve seat (112) during valve opening, which inhibits water flow and causes wear, as is the case with a valve which closes with water pressure, to provide the sleeve (110) in a valve which closes against the water pressure with an axial, annular shoulder (133), the diameter of which is larger than the diameter of the valve seat (112) and on which the frontal surface (162) of the tube (118) nearest the annular shoulder (133) is supported.

Abstract: A stable metal plate for watering tanks having a rear wall of plastic or sheet metal is disclosed. The metal plate functions to give this material the necessary strength at the attachment points such that the rear wall of the tank may be securely attached to a standpipe or wall. The metal plate engages the rear wall from the outside for attachment, and serves to secure the watering tank by clamping the rear wall thereof between the metal plate on one side and the standpipe or wall on the other side by means of a U-bolt or two dowel screws.

Abstract: This disclosure relates to an automatically-catching neck frame for cattle which is adapted to be suspended in a cattle stand. The neck frame includes an inverted essentially U-shaped main frame having a head opening and a neck opening for the animal. A closing lever is mounted on the frame such that when the animal puts his head through the head opening and then lowers its neck downwardly through the neck opening so as to reach the manger, the closing lever will be automatically actuated to close and lock in place so that the animal is prevented from pulling its head out of the frame.
