Title: Separator for low density liquid from water - has automatic valve preventing entrainment of water in separated liquid
Inventor: AMEND KARL-HANS
IPC: E03F5/16
Filed: 1975-09-18
Abstract: Low density liquid separator has inlet and outlet for the liquid to be cleaned and drain for the separated low density liquid. The separation chamber rises to water surface in separation chamber. The low density liquid is removed only and its flow path is opened by a sensing device. This ensures that no water is entrained. The outlet opening (10) of the drain (9) is opened by the low density liquid sensing device (12) which operates the closing element (11). The sensor of the device is immersed in the low density liquid and it also actuate a warning system. The sensor can be a float (5) which closes the draining channel automatically.

Title: Rolling mill with automatic thickness control - has roller gap controlled by tension in rolled material
Inventor: WEBER ERNST ING GRAD
IPC: B21B37/48
Filed: 1976-03-02
Abstract: The rolling mill consists of five separate structures mounted on rollers. Each structure has a pair of rollers for reducing the thickness of the material in successive stages.
