Abstract
Abstract An uninterrupted stream or continuous liquid bridge of an electrically conductive ink is propelled under pressure against a carrier for marking thereon. Symbol formation is effected through the agency of magnetic deflection resulting from interaction of a pair of magnetic flux fields of relative variable intensities. A first of the flux fields is induced about the ink stream by passing a current through it as it travels across the span between the nozzle from which it has been ejected to the carrier; and the second field is disposed about the first. In a preferred embodiment, the ink is an electrical conductor, being a metal or metallic composition with a melting point, such that it will flow at printing temperature but will solidify as it contacts the carrier. By providing an impervious or imperforate endless carrier, for example, of metal fabrication a formed symbol may be removed therefrom to enable reuse of the carrier and metal salvage.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
83 words
In a system for recording discernible patterns: a carrier formed in a closed loop of material of a first color; means for advancing said color; means for impelling a stream of marking material in a color contrasting with said first color toward said carrier, said marking material characterized by the ability to adhere to said carrier; means for diverting said stream to form discernible pattern on said carrier; and means positioned along the path of travel of said carrier for removing said pattern.
Claim 2
Dependent Claim
83 words
In a system for recording discernible patterns: a carrier formed in a closed loop of material of a first color; means for advancing said color; means for impelling a stream of marking material in a color contrasting with said first color toward said carrier, said marking material characterized by the ability to adhere to said carrier; means for diverting said stream to form discernible pattern on said carrier; and means positioned along the path of travel of said carrier for removing said pattern.
Claim 3
Dependent Claim
27 words
In a system according to claim 1, wherein said carrier is constructed of a first metal, and said stream of marking material comprises a molten second metal.
Claim 4
Dependent Claim
130 words
In a system for displaying intelligence patterns; a conductive recording medium; means for directing a stream of electrically conductive material of a color contrasting with the color of said recording medium toward said recording medium toward a point of impingement; means for supplying a variable electric current indicative of intelligence through said stream and said recording medium to induce a varying magnetic field about said stream, means reacting with the induced magnetic field about said stream for diverting said point of impingement of said stream on said recording medium to form intelligence patterns on said medium; means for advancing said recording medium along a path relative to the point of impingement of said stream; and means cooperating with the moving recording medium for removing the intelligence pattern from said medium.
Claim 5
Dependent Claim
130 words
In a system for displaying intelligence patterns; a conductive recording medium; means for directing a stream of electrically conductive material of a color contrasting with the color of said recording medium toward said recording medium toward a point of impingement; means for supplying a variable electric current indicative of intelligence through said stream and said recording medium to induce a varying magnetic field about said stream, means reacting with the induced magnetic field about said stream for diverting said point of impingement of said stream on said recording medium to form intelligence patterns on said medium; means for advancing said recording medium along a path relative to the point of impingement of said stream; and means cooperating with the moving recording medium for removing the intelligence pattern from said medium.
Claim 6
Dependent Claim
25 words
In a system according to claim 3 wherein said recording medium is constructed of metal and said stream of electrically conductive material comprises molten metal.
Claim 7
Independent Claim
217 words
An apparatus for generating a pattern of intelligence symbols which comprises: a reservoir for receiving an electrically conducting liquid medium; a nozzle connected to said reservoir in communication with said medium in said reservoir; means for projecting a liquid stream of said medium in electric continuity from said nozzle; an endless carrier of conductive and impervious material mounted for movement in a cyclic path in interceptive relation with said projected stream of conductive medium to receive an impingement of said stream on said carrier at a point of interception of said stream with said cyclic path of said carrier and to complete a conductive path from said nozzle through said stream to said carrier; means for passing an electric current from said nozzle, through said stream to said carrier to establish a first magnetic field about said stream; means reacting with the fIrst magnetic field for magnetically deflecting said stream of conductive medium to vary the position of said point of interception of said stream on said carrier and to generate a pattern of intelligence symbols from said carrier; and means mounted adjacent to said endless carrier for removing said pattern of intelligence symbols from said carrier to render said carrier ready to again accept information at the point of impingement of said stream on said carrier.
Claim 8
Independent Claim
217 words
An apparatus for generating a pattern of intelligence symbols which comprises: a reservoir for receiving an electrically conducting liquid medium; a nozzle connected to said reservoir in communication with said medium in said reservoir; means for projecting a liquid stream of said medium in electric continuity from said nozzle; an endless carrier of conductive and impervious material mounted for movement in a cyclic path in interceptive relation with said projected stream of conductive medium to receive an impingement of said stream on said carrier at a point of interception of said stream with said cyclic path of said carrier and to complete a conductive path from said nozzle through said stream to said carrier; means for passing an electric current from said nozzle, through said stream to said carrier to establish a first magnetic field about said stream; means reacting with the fIrst magnetic field for magnetically deflecting said stream of conductive medium to vary the position of said point of interception of said stream on said carrier and to generate a pattern of intelligence symbols from said carrier; and means mounted adjacent to said endless carrier for removing said pattern of intelligence symbols from said carrier to render said carrier ready to again accept information at the point of impingement of said stream on said carrier.
Claim 9
Dependent Claim
24 words
An apparatus as defined in claim 5 wherein said removing means comprises a scraper for physically engaging and removing the pattern from said carrier.
