Abstract
Abstract The device comprises rotating shaft fixedly supporting a number of carrying discs. The discs have at their periphery radially arranged U-shaped recesses for receiving and lifting the pipes. The depth of recesses on consecutive discs is progressively varied so as to incline the pipe at an acute angle during the rotation of the discs.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
A device for emptying liquid-containing pipes, comprising a rotating shaft, at least two carrying members fixedly secured in a spaced relation one to the other on said shaft to rotate therewith, each of said carrying members being provided on its circumference with at least one recess extending radially to a distance from the axis of said shaft, said recess at respective carrying members being aligned to receive and support said pipes, and said distances of the bottom points of the recesses from the axis of the shaft being at consecutive carrying members progressively decreased in order to insure during the progress of rotation of the shaft a gradual inclination of the pipe at an acute angle to said axis of the shaft.
Claim 2
Independent Claim
122 words
A device for emptying liquid-containing pipes, comprising a rotating shaft, at least two carrying members fixedly secured in a spaced relation one to the other on said shaft to rotate therewith, each of said carrying members being provided on its circumference with at least one recess extending radially to a distance from the axis of said shaft, said recess at respective carrying members being aligned to receive and support said pipes, and said distances of the bottom points of the recesses from the axis of the shaft being at consecutive carrying members progressively decreased in order to insure during the progress of rotation of the shaft a gradual inclination of the pipe at an acute angle to said axis of the shaft.
Claim 3
Dependent Claim
11 words
The device according to claim 1 wherein said recesses are U-shaped.
Claim 4
Dependent Claim
39 words
The device according to claim 1 wherein said angle of inclination of the pipe is smaller than the friction angle of materials of supporting areas in the recesses and of supported pipes to prevent axial displacement of the latter.
Claim 5
Dependent Claim
14 words
The device according to claim 1 wherein said carrying members have equal outside diameters.
Claim 6
Dependent Claim
20 words
The device according to claim 1 wherein the pipe supporting areas in said recesses are provided with a protective coating.
Claim 7
Dependent Claim
12 words
The device according to claim 5 wherein said coating is of plastics.
Claim 8
Dependent Claim
31 words
The device according to claim 1 wherein the inlet side of each recess is provided with a small protrusion inclined into the opening to prevent the pipe from accidental radial displacement.
Claim 9
Dependent Claim
39 words
The device according to claim 1 further comprising an abutment member secured to an end of the shaft for preventing axial displacement of said pipes, said abutment member being provided with apertures for directing the outflow of said liquid.
