  • Patent number: 6517591
    Abstract: An apparatus and method for treating a cathode material provided on a surface of a continuous thin-film substrate and a treated thin-film cathode having increased smoothness are disclosed. A web of untreated cathode material is moved between a feed mechanism and a take-up mechanism, and passed through a treatment station. The web of cathode material typically includes areas having surface defects, such as prominences extending from the surface of the cathode material. The surface of the cathode material is treated with an abrasive material to reduce the height of the prominences so as to increase an 85 degree gloss value of the cathode material surface by at least approximately 10. The web of cathode material may be subjected to a subsequent abrasive treatment at the same or other treatment station. Burnishing or lapping film is employed at a treatment station to process the cathode material. An abrasive roller may alternatively be used to process the web of cathode material.

  • Patent number: 6037019
    Abstract: The present invention relates to a process for adhering a powder to a substrate. The process includes the steps of: a) providing an oscillating magnetic field, b) continuously introducing into the magnetic field coating material, a substrate, and a means of affixing the coating material to the substrate by forming a fluidized bed of at least the coating material and providing sufficient force to cause the coating material to adhere to the surface of the substrate, and c) continuously collecting the coated substrate.
