    摘要: A mechanically roughened substrate is conveyed through an electrolytic bath and is given a superposed electrochemical roughening, which is carried out by means of electrodes which are arranged in the electrolytic bath at a specific spacing from the substrate. The electrodes are connected to corresponding windings on the secondary side of a three-phase transformer. The corresponding windings on the primary side of the three-phase transformer are connected to a three-phase frequency converter, to which three-phase current is applied via leads. The three-phase frequency converter transforms the line frequency of the three-phase current supplied into a frequency range of about 50 to 300 Hz at a voltage of between about 1 and 380 V.

    摘要: This invention relates to a method for freely suspending a moving web of material in a gaseous medium, which comprises impinging a stream of the gaseous medium over the entire width of one surface of the web in order to produce a first stationary stable pressure zone, forming at least one stationary stable suction zone adjacent said first stationary stable pressure zone, deflecting the gaseous medium passing beyond the edges of the web in order to produce a second stationary stable pressure zone on the opposite side of the web, and regulating said pressure and suction zones in order to maintain the web in a freely suspended state. The invention also includes an apparatus for performing the method.

    摘要: Disclosed is a process for the manufacture of a series of photoconductor webs spaced apart from each other on a carrier web by electrically conductive spacing strips extending transversely of the carrier web, comprising (a) transporting a carrier web having an electrically conductive surface disposed thereon in a feed direction across a backing member and in close proximity to a slot die arranged transversely to the feed direction; (b) pumping a photoconductive coating solution into the slot die; (c) flowing the photoconductive solution intermittently from the slot die orifice onto the carrier web for periods of time sufficient to produce the spaced photoconductor webs, the flow of the coating solution being substantially uniform during each coating period and the entire quantity of coating solution required for each coating photoconductor web being extruded from the slot die orifice in the form of a substantially uniform stream; (d) maintaining the distance between the carrier web and the die orifice constant and so small that the coating solution issuing from the die orifice forms a bridge between the orifice of the slot die and the carrier; and (e) drying the coated material. Also disclosed is an apparatus for carrying out the foregoing process.
