Metalized Dielectric Substrates For Eas Tags
US Patent:
6835412, Dec 28, 2004
Filed:
May 2, 2002
Appl. No.:
10/137195
Inventors:
Thomas F. Burke - Wayland MA
Assignee:
Micrometal Technologies, Inc. - Newburyport MA
International Classification:
B05D 512
US Classification:
427116, 427101, 427124, 427411, 427554
Abstract:
A metallized substrate, such as used to make a resonant circuit tag with inductive and capacitive elements in series, has a thin inorganic or polymeric dielectric layer formed on a metal layer. The inorganic layer may be formed by anodizing a surface of the metal layer. The organic layer may be formed by flexographic printing. In both cases, a via hole is formed through the dielectric layer. A second layer of very thin conductive metal is deposited on the dielectric layer and in the via hole. The substrate is subsequently patterned with an etch resist and then etched to form the inductor coil and the capacitor plates, which are interconnected via the metallized via hole.
Electrical Shielding Material Composed Of Metallized Stainless Steel Monofilament Yarn
US Patent:
2012026, Oct 25, 2012

James E. Haller - Haverhill MA, US
International Classification:
H05K 9/00
US Classification:
174394
Abstract:
A yarn or multi-fiber formed of a plurality of micron diameter stainless steel monofilaments which have been rendered more conductive by one or more coatings of electrolytically-deposited metal or metal alloy materials. The metallized yarn provided by the invention has a very low electrical resistance, with consequent benefit in electrical performance, and is particularly useful as an RFI/EMI shielding material.

Electrical Shielding Material Composed Of Metallized Aluminum Monofilaments
US Patent:
2013000, Jan 10, 2013
Filed:
Jul 3, 2012
Appl. No.:
13/540944
Inventors:
Thomas F. Burke - Wayland MA, US
International Classification:
B32B 15/14, H05K 9/00
US Classification:
174390, 428605
Abstract:
A conductive multi-fiber of aluminum/aluminum alloy monofilaments each of which has been completely and substantially uniformly coated with at least one layer of corrosion-resistant metal or metal alloy materials. The monofilaments are less than 150 microns in diameter that have been drawn separately, then bundled together and lightly twisted, for transport through a low tension electroplating process. The multi-fiber creates an RFI/EMI shielding material with low DC resistance and low weight. The metallization process includes a zincating process that prepares the monofilaments for electroplating and an electroplating process that incrementally builds up the metallized layers.

International Classification:
C25D 554, B05D 304, B05D 118, D06M 102
US Classification:
205159
Abstract:
A polymeric yarn to be coated with electroless nickel is pretreated with an acid and a surfactant to render the yarn surfaces water wettable and not substantially mechanically degraded. All surfaces of yarn formed of polymeric monofilament fibers are coated with a layer of electroless nickel which can also include an electrolytic metal such as copper on the nickel. The yarn is passed through an electroless Ni aqueous bath under little or no tension so that the electroless Ni can coat all of the monofilament surface substantially uniformly. The nickel coated yarn then can be coated with electrolytic metal such as copper in an electrolytic metal plating step.

Diced Retroreflective Sheeting
US Patent:
4202600, May 13, 1980

Assignee:
Avery International Corporation - San Marino CA
International Classification:
G02B 5122
US Classification:
350103
Abstract:
Retroreflective sheeting having a plurality of retroreflective cube corner prisms distributed over one of its surfaces is described. The prisms are disposed in a planar array having a plurality of zones of prisms having differing angular orientations such that the zones have differing retroreflective brightness when illuminated by a light beam at a high angle of incidence. The zones are small enough to be substantially unresolvable by the unaided human eye at the expected viewing distances, so that the sheeting appears to have uniform retroreflective brightness when viewed at a high angle of incidence.
