Patent number: 4402779Abstract: In a method for at least partly metalizing the surface of a laminated component, the layer of material which is to form part of the surface of the component is first metalized; then it is coated, as are the other layers of non-metalized material, with a polymerizable resin; and lastly the coated layers are stacked on the lower part of a mould, which is then subjected to pressure, possibly under heat.Type: GrantFiled: July 17, 1981Date of Patent: September 6, 1983Assignee: Avions Marcel Dassault-Breguet AviationInventor: Fernand J.

Patent number: 4403000Abstract: The present invention is a method for forming a cohesive display object and associated display items. The invention contemplates a display object which is at least partially covered with flock (crushed fiberous material, such as rayon) and at least one display item which back side is at least partially covered with flock. The method comprises the steps of coating at least part of the surface of the display object and the back of the display item with a non-drying adhesive; then covering the coated surface with flock. Contact of the adjacent flock-coated surfaces of the display object and items will create a cohesive force and removably secure the display item to the display object.Type: GrantFiled: October 19, 1981Date of Patent: September 6, 1983Inventor: Victor Gates

Patent number: 4394416Abstract: Disclosed is a film-paper fiber layer laminate comprising a film and a very thin paper fiber layer bonded to the surface of the film. This laminate is prepared by bonding films to both surfaces of a paper so that the adhesive bond strength between the film and the paper is higher than the failure strength of the paper fiber layer and separating the films by delamination. This film-paper fiber layer laminate is excellent in the transparency and dimension stability, and the tearing strength of the film per se is completely retained and the laminate is suitably used as a tracing paper.Type: GrantFiled: May 26, 1981Date of Patent: July 19, 1983Assignee: Azona Co., Ltd.Inventors: Yoshikazu Shimizu, Kathuhiro Yamaguchi

Patent number: 4391853Abstract: The disclosed adhesive products include a carrier sheet bearing a polymeric film and an adhesive layer, overlying the film as in dry transfers or underlying the film in products such as wire markers and other labels, or there may be adhesive layers both over and underneath the polymeric film. A constituent initially contained in the polymeric film layer migrates into an ordinarily non-tacky precursor of the adhesive layer, thereby rendering the precursor tacky. The precursor layer becomes adhesive only where it is opposite the polymeric film, being non-tacky outside the area of the film. In important applications, the common area of film and adhesive layers does not cover the whole carrier sheet. Both the adhesive precursor layer and the polymeric film may include portions extending outside the common area.Type: GrantFiled: December 10, 1979Date of Patent: July 5, 1983Assignee: The Datak CorporationInventor: David W. Pointon

Patent number: 4381998Abstract: An improved rigid filter plate for sludge dewatering is comprised of a filter element of two or more sizes within the range of 8 to 100 grid of jagged, irregular hard particles of aluminum oxide or similar materials, and of a supporting element of larger particles all bonded with an adhesive bonding agent. The particles in the filtering element increase in average diameter progressing from the upper surface to the lower surface of the element. A process for manufacturing the improved rigid filter plate is also set forth.Type: GrantFiled: August 27, 1981Date of Patent: May 3, 1983Assignee: U.S. Environmental Products, Inc.Inventors: Robert L. Roberts, Felix G. Janssen

Patent number: 4364892Abstract: A process for the continuous modification of the surface portion only of a foamed plastic web to impart high mechanical resistance with retention of air permeability and elasticity comprises preheating the web to a temperature below its melting point, passing the preheated web through the nip of a calendar and withdrawing the web from the calender under tension. The calendar comprises a pressure roller heated to a temperature above the melting point of the web and a backing roller which is not heated.Type: GrantFiled: July 20, 1979Date of Patent: December 21, 1982Inventors: Helmut Rehlen, Jurgen Roellinghoff
