Abstract
Abstract A device for measuring the current amplitude in busbars and other current feeders to the electrodes of a cell for the electrorefining of copper, comprises a Hall generator which can be set with a yoke upon the conductor or bar and which is provided with an amplifier or discriminator circuit operating a display preferably in the form of a linear array of light-emitting diodes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
In an electrolysis system in which a current carrier is connected between a current source and an electrode, a device for monitoring the amplitude of the current in said carrier, said device comprising: a Hall generator; means for mounting said Hall generator on said carrier; a direct current source connected to said Hall generator for energizing same; an amplifier and discriminator circuit connected to said Hall generator and responsive to an output thereof representing a magnetic field around said carrier; a display connected to said amplifier and discriminator circuit for displaying the current in said carrier; and means for automatically connecting said source upon the mounting of said Hall generator on said carrier.
Claim 2
Dependent Claim
113 words
In an electrolysis system in which a current carrier is connected between a current source and an electrode, a device for monitoring the amplitude of the current in said carrier, said device comprising: a Hall generator; means for mounting said Hall generator on said carrier; a direct current source connected to said Hall generator for energizing same; an amplifier and discriminator circuit connected to said Hall generator and responsive to an output thereof representing a magnetic field around said carrier; a display connected to said amplifier and discriminator circuit for displaying the current in said carrier; and means for automatically connecting said source upon the mounting of said Hall generator on said carrier.
Claim 3
Dependent Claim
26 words
The device defined in claim 1, further comprising means for automatically disconnecting said source from said Hall generator upon dismounting said Hall generator from said carrier.
Claim 4
Dependent Claim
31 words
The device defined in claim 1, further comprising means for automatically disconnecting said source from said Hall generator following a predetermined time period after mounting said Hall generator on said carrier.
Claim 5
Dependent Claim
137 words
In an electrolysis system in which a current carrier is connected between a current source and an electrode, a device for monitoring the amplitude of the current in said carrier, said device comprising: a Hall generator; means for mounting said Hall generator on said carrier; a direct current source connected to said Hall generator for energizing same; an amplifier and discriminator circuit connected to said Hall generator and responsive to an output thereof representing a magnetic field around said carrier; an iron yoke having segments flanking said Hall generator and at least partially surrounding said carrier for concentrating said magnetic field around said carrier; a display connected to said amplifier and discriminator circuit for displaying the current in said carrier; and means for automatically connecting said source upon the mounting of said Hall generator on said carrier.
Claim 6
Dependent Claim
137 words
In an electrolysis system in which a current carrier is connected between a current source and an electrode, a device for monitoring the amplitude of the current in said carrier, said device comprising: a Hall generator; means for mounting said Hall generator on said carrier; a direct current source connected to said Hall generator for energizing same; an amplifier and discriminator circuit connected to said Hall generator and responsive to an output thereof representing a magnetic field around said carrier; an iron yoke having segments flanking said Hall generator and at least partially surrounding said carrier for concentrating said magnetic field around said carrier; a display connected to said amplifier and discriminator circuit for displaying the current in said carrier; and means for automatically connecting said source upon the mounting of said Hall generator on said carrier.
Claim 7
Dependent Claim
26 words
The device defined in claim 4, further comprising means for automatically disconnecting said source from said Hall generator upon dismounting said Hall generator from said carrier.
Claim 8
Dependent Claim
31 words
The device defined in claim 4, further comprising means for automatically disconnecting said source from said Hall generator following a predetermined time period after mounting said Hall generator on said carrier.
