摘要： The invention relates to the development of lithographic printing plates and comprises the application of a thin film of developer solution to each plate in a controlled manner using a jetting printhead. Sensors and control means activate and deactivate the jetting printhead in response to the presence or absence of a plate. The developer is allowed to dwell on the plate as it is conveyed across a support structure for a sufficient time to allow for percolation into and/or dissolution of the soluble areas of the coating and is then washed off and sent to waste.

摘要： Certain types of lithographic printing plates are activated by preheating while certain other types are post heated to harden the coating. A platen having a large mass compared to the mass of a printing plate is heated and maintained in the exact temperature range to which the printing plate is to be heated. A printing plate is brought into heat exchange contact with the platen for the period of time required to heat the printing plate to the temperature of the platen. The printing plate may be heated while resting in a fixed position on the platen or while the printing plate is carried over the platen by a continuous thin metal conveyor belt in intimate contact with both the platen and printing plate.

摘要： A substrate metal such as aluminum or titanium, usually in the form of a web, is anodized to form a porous unsealed oxide coating. An inexpensive core metal such as copper or chromium is then electrodeposited in the pores of the oxide coating to form metal nodules extending above the oxide coating in a bulbous, undercut configuration. A second metal, usually an expensive catalytic metal, is deposited onto the surface of the core metal nodules by electro or chemical deposition. A large surface area of catalyst is formed with the use of a minimum amount of catalyst metal. The nodules may be liberated from the substrate metal surface by dissolving the oxide layer and releasing discrete particles to form a fine catalyst powder.
摘要翻译：通常以网状形式的基底金属如铝或钛，被阳极化以形成多孔未密封氧化物涂层。然后将廉价的核心金属例如铜或铬电沉积在氧化物涂层的孔中，以形成在球形，底切构型中在氧化物涂层上方延伸的金属结核。通过电沉积或化学沉积将第二金属（通常是昂贵的催化金属）沉积在芯金属结核的表面上。使用最少量的催化剂金属形成催化剂的大表面积。可以通过溶解氧化物层并释放离散的颗粒以形成细小的催化剂粉末，从基底金属表面释放结节。

摘要： According to the invention there is provided an electrochemical process for applying a firmly bonded insoluble metal oxide-organic complex on a metal surface by employing the metal as anode and a water-soluble polybasic organic acid as electrolyte. The polybasic acid may be a polyphosphonic acid, polyphosphoric and polycarboxyl acid, or polysulfonic acid and is advantageously polymeric. Polyvinyl phosphonic acid (PVPA) is a preferred electrolyte. Direct current is used. The insoluble metal oxide-organic complex formed is composed of anodic oxide combined with polyacid, which forms a protective layer on the metal of improved corrosion resistance. The metal oxide-organic complex is well-suited to bond light sensitive coatings thereto. The metal may be steel, aluminum or magnesium. The process is economical and the product novel.

摘要： According to the invention there is provided an electrochemical process for applying a firmly bonded insoluble metal oxide-organic complex on a metal surface by employing the metal as anode and a water-soluble poly basic organic acid as electrolyte together with a strong inorganic acid such as phosphoric acid or further admixed with another strong inorganic acid such as sulfuric. The polybasic acid may be a polyphosphonic acid, polyphosphoric and polycarboxyl acid, or polysulfonic acid and is advantageously polymeric. Polyvinyl phosphonic acid (PVPA) is a preferred electrolyte. Direct current is used. The insoluble metal oxide-organic complex formed is composed of anodic oxide combined with polyacid, which forms a protective layer on the metal of improved corrosion resistance. The metal oxide-organic complex is well-suited to bond light sensitive coatings thereto. The metal may be steel or aluminum. The process is economical and the product novel.
