Abstract
Abstract A device for the cracking of organic products in liquid phase by means of a submerged intermittent electric arc wherein the electric arc is produced between stationary electrodes and movable electrodes which are secured to a rotary support at uniform angular intervals over a circumference which is cocentric with the axis of rotation of said support. The stationary electrodes and the movable electrodes which are in cooperating relation therewith are so arranged that the free extremities of the movable electrodes come successively into contact with the free extremities of the stationary electrodes in a plane at right angles to the axis of rotation of the movable electrode support.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
54 words
A device as defined in claim 1, characterized in that the movable electrodes are designed in the form of prisms having a trapezoidal cross-sectional shape, one of the bases of which constitutes the flat contact face of the electrode, said electrodes being advantageously locked in position by keying after insertion in the rotary support.
Claim 2
Dependent Claim
30 words
A device as defined in claim 1, characterized in that it comprises one or a number of pairs of movable electrodes which are adapted to cooperate with two stationary electrodes.
Claim 3
Dependent Claim
82 words
A device as defined in claim 3, characterized in that the rotary support which carries the movable electrodes is constituted by radial arms which are distributed in a number corresponding to the number of movable electrodes about a common hub, the front portions of the movable electrodes considered in the direction of rotation being inserted in the face of said radial arms which is located opposite to the stationary electrodes whilst the projecting rear portions of said movable electrodes are left free.
Claim 4
Dependent Claim
82 words
A device as defined in claim 1 characterized in that the rotary support which carries the movable electrodes is constituted by radial arms which are distributed in a number corresponding to the number of movable electrodes about a common hub, the front portions of the movable electrodes considered in the direction of rotation being inserted in the face of said radial arms which is located opposite to the stationary electrodes whilst the projecting rear portions of said movable Electrodes are left free.
Claim 5
Dependent Claim
54 words
A device as defined in claim 5, characterized in that the movable electrodes are designed in the form of prisms having a trapezoidal cross-sectional shape, one of the bases of which constitutes the flat contact face of the electrode, said electrodes being advantageously locked in position by keying after insertion in the rotary support.
Claim 6
Dependent Claim
38 words
A device as defined in claim 5, characterized in that the arms which carry the movable electrodes are designed in the form of fins each having a portion of surface which is inclined in the direction of rotation.
Claim 7
Dependent Claim
54 words
A device as defined in claim 7, characterized in that the movable electrodes are designed in the form of prisms having a trapezoidal cross-sectional shape, one of the bases of which constitutes the flat contact face of the electrode, said electrodes being advantageously locked in position by keying after insertion in the rotary support.
