Patent BR-0318226-A (BR)
Inventor: BENACHENHOU AMINE
IPC: B01D17/022
Filed: 2003-04-01
Abstract: A method and apparatus for separating immiscible liquids in a dispersion containing an aqueous liquid and at least one dispersed non-aqueous liquid by passing the dispersion through a series of absorbents, preferably polymeric. The direction of the flow through the absorbent is periodically changed. The period required before a change of the flow direction is established by the differential pressure. There is a gradual increase in the differential pressure across the absorbents which indicates a blockage due to viscous oil and/or solids. The product produced by the method and the apparatus of the invention is a polished non-aqueous phase and a polished aqueous phase both having low contaminant levels. In a preferred embodiment when solids are also present in the dispersion, a solids stream is also recovered.

Abstract: In order to allow an adjusting of the bending tools to a given diameter of the wire being bent allowing the producing of the requisite bending radius a central mandrel which forms two bending or forming, respectively, jaws is replaceable together with a shearing tool. To this end a hollow shaft is mounted at the rear of the central mandrel, which shaft is mounted to a supporting shaft by means of a screw joint. The supporting shaft is supported in turn rotationally and can be rotated by means of a motor in order to disconnect the central mandrel. By mentioned rotation the screw joint is released. A special coupling of the shearing tool to an axially movable operating shaft allows a simultaneous disconnecting of the shearing tool together with the central mandrel. A bending mandrel is mountable at locations having various radial distances from the central mandrel. A cover plate provided with a position control element operates together with proximity switches such that two defined initial angular positions of the bending mandrel is maintained independently from mentioned adjustments.

Abstract: A description is given of an articulated coupling, particularly for rail vehicles, for the transmission of the motor power from a driving hollow shaft mounted on the vehicle frame or the bogie frame to a driving axle with limited mobility surrounded by the said hollow shaft. The essential components of this coupling are a first flange (1), rigidly connected to the hollow shaft, a second flange (4), rigidly connected to the driving axle (3), and two pairs of links (9, 10 and 11, 12 respectively) and an intermediate member (15) which surrounds the driving axle in a floating manner and on which the links are supported. To achieve optimum symmetry about the centre, the two flanges (1, 4) are arranged in alignment, all the links (9, 10 and 11, 12) are of equal length and the links are arranged in such a way relative to one another that the projections of the pivot points form the corners of a square in a plane transverse to the driving axle (3). The pivoted support of the two opposite links (10, 12) on the intermediate member is in each case provided in their centre. These two links (10, 12) are bent at an obtuse angle towards the driving axle (3) such that the pivot points of the intermediate member (15) lie on a circle which runs through the corners of the abovementioned square. Rubber metal joints known per se are employed at all the pivot joints, giving the joints a limited elasticity and thus enabling them to take up annular displacement too. <IMAGE>
