Patent number: 5156880Abstract: A method and apparatus for electrostatically spraying conductive coating material onto objects, primarily large extended objects, by charging with a relatively large charge the space behind the surface to be coated. With hollow objects, such as automobile bodies, the space within the body is charged. The space is charged by spraying an electrostatically charged atomized water mist into the space which evaporates charging the space and object surface. An electrostatic field is produced between the surface and the gun which, along with the supply of conductive material to which it is connected, is grounded. The gun discharges a film of coating which is atomized into droplets. The field inductively charges the film fringe and thus the droplets which are then attracted onto the large charged surface.Type: GrantFiled: February 19, 1991Date of Patent: October 20, 1992Assignee: Nordson CorporationInventor: Ion Inculet

Patent number: 5153025Abstract: There is disclosed a method for the continuous marking of electric strands with which annular markings, which are limited in axial direction, are applied to the surface of the strands by means of color jets. The color jets emerge under pressure from at least one nozzle which is driven by an electrical oscillation system, the frequency of which is controlled proportionally to a rate of withdrawal of the strands. For an easy changing of the axial distance between the markings, square pulses are fed to the oscillation system from a converter which converts electrical d.c. voltage into a square waveform signal at a specific frequency. The square waveform drives the oscillation system at the specific frequency. As a desired value, the converter is fed a d.c. voltage which is proportional to the rate of withdrawal of the strand.Type: GrantFiled: November 30, 1990Date of Patent: October 6, 1992Assignee: Kabelmetal Electro Gesellschaft mit beschrankter HaftungInventors: Wolfram Klebl, Rainer Brunn

Patent number: 5147681Abstract: The method of the present invention begins with the unloading of the garments delivered by the customer. After unloading, the garments are sorted and counted and then placed on moveable racks for transportation to a separate storage area nearby. Selected garments are then moved from the storage area to a temporary receiving area near zones known as painting cells, where the garments are taken and hung from hooks attached to a variable speed electronically operated overhead track conveyor. The conveyor moves the garments along an oval shaped track pattern at a constant speed as paint is applied by workers stationed at various locations along the conveyor route. Various paint application methods are utilized during this stage of the operation, including the use of spray bottles and airbrushes.Type: GrantFiled: April 13, 1990Date of Patent: September 15, 1992Assignee: L.A. Air Line, Inc.Inventor: Dennis J. Maroney

Patent number: 5145527Abstract: Apparatus particularly adapted for applying foamed treating liquor to a flat width of a traveling non-woven textile substrate includes a longitudinal tubular foam distribution nozzle one side of which has a plurality of closely-spaced staggered apertures for engaging and applying pressurized foam widthwise across the substrate and a driven drum opposed to the nozzle engaging widthwise the opposite side of the substrate for imparting traveling movement to the substrate. The drum and nozzle cooperate to compress the substrate therebetween in covering relation over the apertures to prevent lateral escape of the foam therefrom and to confine the emission of foam therethrough, thereby to uniformly control foam application across the substrate width as it travels by the nozzle. Limited contact of the apparatus with the substrate prevents frictional pulling and structural damage thereto. The drum is perforated for escape of the air component of the foam and to enhance foam penetration of the substrate.Type: GrantFiled: April 9, 1982Date of Patent: September 8, 1992Assignee: Owens-Corning Fiberglas CorporationInventors: Graham F. Clifford, James K. Turner, Mack W. Spurrier

Patent number: 5141774Abstract: The present invention discloses an apparatus and process for coating hollow objects at precise bands within the internal cavity of the object. The process utilizes centrifugal force to apply the fluid to the object. A probe is moved from underneath the object thereby utilizing gravitational forces to prevent spillage of the material from the probe. A computer controls the pumping rate, the vertical movement of the probe and the rotational speed of the probe to allow the machine to precisely coat a band on the internal cavity of an article. The computer controlled operation eliminates the necessity to waste material. One application of the invention is in the coating of the threads of nuts with Teflon.Type: GrantFiled: January 13, 1989Date of Patent: August 25, 1992Inventors: Michael W. Prittinen, Scott A. Hale, Scott Bellinger, Steve Nisbett, Gary Mulder, Timothy Gaipa

Patent number: 5135774Abstract: A method to impart coffee stain resistance to polyamide fibers such as those found in textile substrates (e.g., carpets). The method includes preparing an aqueous dispersion of charged microfine beads of either (i) a copolymer selected from the group consisting of a hydrolyzed aromatic-containing vinyl ether maleic anhydride copolymer, a half ester of an aromatic-containing vinyl ether maleic anhydride copolymer, and mixtures thereof, or (ii) an aromatic-containing acrylate copolymerized with an acid selected from the group consisting of acrylic acid and maleic acid, immersing the polyamide fiber in the aqueous dispersion so that the beads contact and coat the fiber via an electrostatic attraction. The aqueous dispersion is prepared by dissolving the polymer into a water-soluble solvent to form a solution, injecting the solution into water, and evaporating the solvent.Type: GrantFiled: March 27, 1990Date of Patent: August 4, 1992Assignee: Allied-Signal Inc.Inventors: Lidia T.
