Transcript of Process for coating hollow objects
Apparatus for Electrolytic Treatment of Wire U.S. Patent 5,478,457. Dec. 26, 199.5 M. Catteeuw, Zwevegem and P Cosaert, Kortrijk, both of Belgium
An apparatus for the continuous electro- lytic treatment of wire-shaped objects com- prising an elongate tank enclosing an elec- trolyte bath; and means for moving at least one object in a treatment direction through the bath past a succession of electrodes.
Sputtering Apparatus U.S. Patent 5,478,459. Dec. 26, 1995 R. Latz, assignor to Leybold AG, Hanau, Germany
A plasma sputtering apparatus with mi- crowave enhancement.
Method of Regenerating Nickel Sulfamate Plating Baths U.S. Patent 5,478,461. Dec. 26, 1995 6. Sala et al, assignors to Framafome, Courbevoie, France
A method of regenerating a passivated nickel plating electrolytic bath containing nickel sulfamate, prior to nickel plating, comprising subjecting the bath to a reduc- tion treatment until the bath is unable to be used for electrolytic nickel plating; and slowly oxidizing the bath and stopping the
oxidation when the bath is appropriate to be used for nickel plating.
Process For Forming Polyimide- Metal Laminates U.S. Patent 5,478,462. Dec. 26, 1995 D.P Walsh, assignor to Polyonics Corp. Inc., Newbuvport, Mass.
A process for coating at least one surface of a polyimide sheet with copper in the absence of an adhesive comprising contact- ing with a one-phase solution comprising a diamine at a temperature sufficient to ren- der at least one surface uniformly and sub- stantially completely hydrophilized; treat- ing with a catalyst to render the surface receptive to the electroless deposition of nickel or cobalt; depositing nickel or cobalt by electroless deposition; and depositing copper by electrolytic deposition to form at least one exposed copper coating on the polyimide sheet.
Paint Stripper U.S. Patent 5,478,491. Dec. 26, 1995 CI? Jarema, assignor to Specialty Environmental Technologies Inc., Auburn Hills, Mich.
A paint stripper having a long shelf life and improved odor, consisting essentially of 10 to 55% by weight of d-limonene; 45 to 90% N-methyl pyrrolidone; and an ef-
fective amount of an evaporation inhibiting agent, which is at least partially insoluble in the composition and forms a film upon exposure to air.
Apparatus to Control Zinc Phosphate Solution U.S. Patent 5,478,529. Dec. 26, 1995 T Sobata and K. Takeshita, assignors to Nippon Paint Co. Ltd., Osaka, Japan
An activity control apparatus for con- trolling zinc phosphate treatment solution in a prescribed range, comprising a treat- ment vessel containing zinc phosphate treatment solution comprising complex hy- drofluoric acid as an activity material; and means for adding simple fluoride solution to thereby control the activity of the zinc phosphate treatment solution.
Process for Coating Hollow Objects U.S. Patent 5,478,597. Dec. 26, 1995 K. Jbrgens, Wuppertal, Germany
A continuous process for coating cans, each can having a central axis and an open- ing, using a submersion bath filled with a liquid coating having a surface, the sub- mersion bath having fluid coating nozzles and air nozzles submerged in the liquid.
