Abstract: A reel for a life-line comprising a frame, a winding member rotatably journalled in said frame and damping means connected on the one hand with the frame and on the other hand with the winding member for counteracting the rotation of the winding member, said damping means comprising at least two piston pumps axially arranged side by side in a pump housing and cam discs, the cylinder chambers of said piston pumps communicating with one another by an axial channel forming a restriction and the pistons being in contact with the surfaces of the cam discs relatively off-set by half a cam interval, said winding member extending around the damping means, said cam discs being formed by rings and each piston pump being radially arranged inside a ring, while the axial channel is in line with a bore extending from a head face of the pump housing.

Abstract: The invention relates to a reel for a life-line comprising a frame, a winding member journalled in said frame so as to be rotatable about a rotary axis, damping means connected on the one hand with the frame and on the other hand with the winding member and counteracting the rotation of the winding member, said damping means comprising at least one cam member and a plurality of piston pumps rotatably co-operating herewith along a relative path of movement with respect to one another and each having a cylinder and a piston displaceable therein and being in contact with the cam member, while of each pair of pumps, whose pistons are moved in opposite senses by the cam member, the cylinders communicate with one another through a channel having a restriction.

Abstract: An apparatus for separating a mixture of liquids of different specific gravities, e.g. oil and water, comprising a vessel containing a settling chamber, an upper chamber and a movable partition between said chambers for controlling the process, conduits for the supply of mixture and the separate discharges of the component liquids and a second vessel containing a collecting chamber and a final liquids separating device and associated therewith conduits for the component liquids.

Abstract: An apparatus for separating a mixture of liquids of different specific gravities, e.g. oil and water, comprising a vessel containing a settling chamber and associated with conduits for the supply of mixture to be separated and the separate discharges of the components of the mixture, respectively, and with means to suppress completely or to reduce considerably turbulences occurring in the settling chamber.

Abstract: An apparatus to separate a mixture of liquids of different specific gravities, e.g. oil and water, in which in a settling vessel for liquids the buoyancy of the lighter liquid (oil) is used to move a diaphragm upwards to control the discharge of lighter liquid from said vessel and means are provided to check temporarily or to slow down the downward movement of said diaphragm during said discharge.
