摘要： A process for making printing plate material suitable for imaging by laser radiation. A metal substrate is electrocoated in a bath containing a polymeric resin and laser-sensitive particles, thereby depositing a laser ablatable layer on a principal surface of the metal substrate. In one embodiment, the laser-ablatable layer is treated with a corona discharge for a time sufficient to render the layer non-ink wettable. In other preferred embodiments, the laser-ablatable layer is overcoated with an overlayer such as a non-ink wettable silicone layer or a water-wettable layer comprising an organophosphorus polymer, preferably a copolymer of acrylic acid and vinylphosphonic acid.

摘要： In a process of fragmenting and segregating metallic components fabricated from different aluminum alloys, a method of removing tramp impurities therefrom is provided. The method comprises the steps of providing a feedstock comprised of the metallic components having mixed therewith tramp impurities, the alloys having different incipient melting temperatures. The feedstock is heated to effect incipient melting of the component having the lowest incipient melting temperature and is then agitated sufficiently to cause the component having the lowest incipient melting temperature to fragment. The agitation also causes the fragmented component to scour tramp impurities from the unfragmented feedstock. The fragmented components and tramp impurities are segregated from the unfragmented feedstock and fragmented components are separated from the tramp impurities.

摘要： Magnesium is produced by a thermal reduction process in a reaction-condensation system having a reaction zone and a condensation zone. According to this process, a reducing agent containing a mixture of ferrosilicon and at least 25 wt. % aluminum skim is contacted or reacted in the reaction zone with a calcium-silicon-aluminum-magnesium oxide slag to produce magnesium vapor. The magnesium vapor is transported from the reaction zone to the condensation zone and condensed therein.

摘要： A continuous process is disclosed for the recovery of an aluminum alloy from aluminum scrap containing more than one alloy. The recovery is made in a manner which will conserve energy. The process comprises providing a feedstock containing at least two components therein comprised of different aluminum alloys, the components having at least parts thereof joined to each other. The feedstock is treated to cause the joined components to become detached from each other. One of the detached components is separated from the remainder of the feedstock, melted and thereafter continuously cast without substantially upgrading the composition thereof to provide a cast alloy having a composition substantially the same as that from which the separated component was fabricated. The treating may be accomplished by heating the feedstock to a temperature sufficiently high to render fracture sensitive the component having the lowest incipient melting temperature.

摘要： A method for purifying aluminum that contains impurities, the method including the step of introducing such aluminum containing impurities to a charging and melting chamber located in an electrolytic cell of the type having a porous diaphragm permeable by the electrolyte of the cell and impermeable to molten aluminum. The method includes further the steps of supplying impure aluminum from the chamber to the anode area of the cell and electrolytically transferring aluminum from the anode area to the cathode through the diaphragm while leaving impurities in the anode area, thereby purifying the aluminum introduced into the chamber. The method includes the further steps of collecting the purified aluminum at the cathode, and lowering the level of impurities concentrated in the anode area by subjecting molten aluminum and impurities in said chamber to a fractional crystallization treatment wherein eutectic-type impurities crystallize and precipitate out of the aluminum. The eutectic impurities that have crystallized are physically removed from the chamber. The aluminum in the chamber is now suited for further purification as provided in the above step of electrolytically transferring aluminum through the diaphragm.

摘要： A printing apparatus has an array of cartridges for printing a web of e.g. paper passing through the array, and one or more units containing printing medium. The cartridges each are capable of transferring the printing medium from the unit(s) to the web. The unit(s) and the cartridges of the array are relatively movable, to allow the unit(s) to interact successively with at least two of the cartridges. In this way it is possible to change printing from one cartridge to another, allowing changes to be made to what is printed, without halting the movement of web significantly. The present invention also proposes that the cartridges may have printing cylinders of different sizes, and furthermore that a mobile unwind stand may be used to move web material to the printing apparatus, and the web output from the printing apparatus processed by sheet folding techniques.

摘要： The apparatus comprises two parallel and spaced apart conveyor belts and a toothed take-along belt guided parallel to and interposed between the two conveyor belts. The take-along belt has a thickened or otherwise rigidified section providing an engagement region. The belt runs at constant speed, faster than the conveyors. The engagement region runs slightly beneath the conveying surface of the conveyors until it reaches an engagement location, at which it may halt and then be instantaneously raised and restarted in response to a signal indicating an adjacent batch or leaves to lift the leaves off the conveyor belt and cause them to be moved with greater velocity than the conveyor belts to the delivery end thereof where they are stacked.

摘要： A rotatable furnace for treatment of metallic scrap is fed metallic scrap comprising at least two metallic components having different incipient melting temperatures. The furnace is heated to a temperature at least equal to the lowest incipient melting temperature of the metallic components but less than the incipient melting temperatures of other components in the scrap while rotating the furnace to agitate the scrap. The combination of heating to the incipient melting temperature and agitating the scrap serves to fragment the metallic component having the lowest incipent melting temperature. The scrap is then removed from the furnace, and the scrap is segregated by particle size. Fines representing dirt and other impurities may also be separated therefrom.
