Abstract: For separating an emulsion comprising substantially a heavier and a lighter liquid there is used a plurality of superimposed, liquid-filled, shallow separation chambers which have a lower outlet for separated heavier liquid, an upper outlet for separated lighter liquid, and an emulsion-inlet remote from the outlets. The separation chambers are maintained under an overpressure by causing the heavier and the lighter liquid, separated in the chambers by self-separation under the action of gravity, to pass from the chambers via a respective one of two pressure-holding vessels containing a respective heavier or lighter liquid. The emulsion is fed batchwise into at least one separation chamber at a time, at a temperature greater than the temperature of the liquid already present in the chamber, and in a volumetric amount which is less than the volume of the chamber.

Abstract: A thread-storage and delivery device, which includes a storage drum on which a thread is wound to form a thread storage and from which the thread is withdrawn for supply to a textile machine. The drum is formed from a plurality of elongated rods disposed in a cylindrical pattern about the drum axis. The rods define an outer peripheral surface on which the thread windings are engaged. A thread-advancing device has portions thereof projecting radially outwardly between the rods for engaging the thread windings to slide them axially along the peripheral surface. Each rod is provided with a plurality of parallel narrow grooves extending axially thereof, which grooves are separated by narrow axially extending ribs. The outer free edge of each rib defines a narrow axially elongated surface section which defines a part of the peripheral drum surface and is engaged by the thread windings.

Abstract: A transport device is provided which is driven by an electromotor and on which more than two bobbin supports are mounted and are movable in common such that the respective bobbin to be unwound can be brought into the required association with respect to a stationary thread eye. A thread scanning device is provided adjacent the unwound thread for detecting the thread as it jumps from the bobbin just emptied to the next bobbin. This thread scanning device is connected with the electromotor such that, when the thread scanning device responds, the motor moves the transport device to such an extent that the next bobbin is brought into the required association with respect to the stationary thread eye.
