Abstract: PRINTING IS EFFECTED BY FIRST PLACING AN ELECTRIC CHARGE OVER THE COATED SURFACE OF A ZINC OXIDE COATED WEB OF PAPER. THIS CHARGE IS NEUTRALIZED IN SELECTED IMAGE AREAS BY A PROJECTED LIGHT IMAGE. THE WEB IS THEN PASSED BETWEEN A GROUND ELECTRODE AND A SMOOTH INK BEARING CONDUCTIVE DRUM CHARGED TO A POTENTIAL ON THE ORDER OF THAT OF THE UNNEUTRALIZED PORTIONS. LIQUID INK FROM THE DRUM IS BODILY ATTRACTED FROM THE DRUM TO THE NEUTRALIZED IMAGE AREAS IN AN UNSUPPORTED COLUMN.

Abstract: INSULATIVE FILM COATINGS FORMED UPON SEPARATED METAL WIRES BY ELECTROPHORETIC DEPOSITION FROM AQUEOUS POLYMER LATEX DISPERSIONS ARE FOUND TO BE CONJOINABLE INTO SUPPORTING STRUCTURES WHICH ARE THICK BY COMPARISON TO DIAMETERS OF ENCLOSED WIRES AND WHICH HAVE PRE-DETERMINABLE DIMENSIONAL PROPERTIES WHEN SOLIDIFIED. ELECTRICAL SIGNAL TRANSMISSION LINES ARE MADE AT REDUCED COST BY THIS PROCESS. WIRES IN SUCH LINES ARE HELD CLOSE TOGETHER WITHOUT TOUCHING AT SPACING DISTANCES HELD TO TIGHT TOLERANCES. THE ELECTROPHORETICALLY APPLIED INSULATING-SUPPORTING STRUC-
TURE OF THESE LINES CAN BE PROVIDED WITH SUCH OTHER DESIRABLE FEATURES AS INTERNAL CONTINUITY (I.E. CRACKFREE, VOID-FREE), THERMAL STABILITY, ABRASION RESISTANCE, HIGH DIELECTRIC STRENGTH, FLEXIBILITY, AND UNIFORM COHESION TO THE SUPPORTED WIRES.-

Abstract: Electrically functional and decorative surface coatings- which are durable, attractive in appearance and resistant to corrosion and most importantly have long-lasting retention of foregoing properties under service conditions- are produced by reactive absorption of unsaturated oils into oxides of certain metals and metal alloys. The oil-treated oxide surfaces- especially after periods of in-service use- have lower contact impedance, higher conductivity, better retention of appearance and greater resistance to wear and corrosion than the untreated oxides. It appears that a highly stable interfacial compound is formed between the oil, the oxide coating and possibly the unoxidized basic metallic material, which differs considerably from the oxide in stability and general physical composition. Existence of this compound is evidenced by the heightened ability of the treated finish to withstand corrosion and scratching, and the tendency of the finish to actually harden and acquire greater wear resistance and permanence of appearance with age.
Abstract translation: 电气功能和装饰性表面涂层，其耐用性，外观吸引力和耐腐蚀性，最重要的是在使用条件下对前述性能的持久保留 - 是通过将不饱和油反应吸收到某些金属和金属合金的氧化物中产生的。 经过油处理的氧化物表面 - 特别是在使用期间 - 具有比未处理的氧化物更低的接触阻抗，更高的导电性，更好的保持外观和更大的耐磨性和腐蚀性。 似乎在油，氧化物涂层和可能的未氧化的碱性金属材料之间形成高度稳定的界面化合物，其与氧化物的稳定性和一般物理组成显着不同。 这种化合物的存在通过处理后的表面处理耐腐蚀和划伤的能力提高，以及涂层实际上硬化和获得更大的耐磨性和耐老化性的趋势来证明。

CPC classification number: C25D13/22
Abstract: Normally difficult to remove coatings of certain polymeric substances, including a polytetrafluoroethylene, are removed by the presently disclosed electrical stripping technique. The coatings are deposited by electrophoresis on a conductive surface of an object used as an electrode and stripped or removed from the same surface by applying a voltage of opposite polarity while the coating particles are still in an uncoalesced condition due to retention of electrolyte fluid between the particles. Certain of these coatings are strippable even after removal of the base electrode from the electrolyte medium, provided that sufficient electrolyte moisture is retained to keep the coating in a solvated condition until reimmersion and application of the reverse voltage. The deposition and stripping actions are repeatable an indefinite number of times for particular coating substances under particular conditions. This is used in a closed system to construct specific devices based on selectively variable thermal resistance effects and visual indication effects. These effects have an associated memory property in the sense that the effect persists indefinitely upon removal of the electromotive force which is depositing or stripping the coating.
