Filed:

Jul 30, 1992

Appl. No.:

7/921399

Inventors:

Louis A. Graham - Greensboro NC

Assignee:

Burlington Industries, Inc. - Greensboro NC

International Classification:

G01D 1518
B42D 1500
B41M 314

US Classification:

347 2

Abstract:

A method and apparatus for forestalling counterfeiting is disclosed which allows a counterfeit document to be identified relatively easily by an average person. The present invention employs a fluid jet applicator to record a unique, random pattern on each of a set of documents (e. g. , paper currency, corporate or government bonds or any other document or important paper). Thus, a fluid jet applicator is controlled to produce a truly unique pattern on a set of original documents. Any counterfeiter who merely copies one (or a number) of the genuine documents would be left with a plurality of identical (i. e. , non-unique) documents which may then be readily identified by a recipient as not being genuine.

Assignee:

Burlington Industries, Inc. - Greensboro NC

International Classification:

D06B 102

US Classification:

68205R

Abstract:

A fluid jet applicator is disclosed which senses orifice plate fluid pressure and the fabric substrate speed and electronically controls the flow of fluid by modulating fluid pressure in accordance with the speed and characteristics of the fabric substrate. In this fashion, a highly uniform solid shade is applied across the width of the fabric. The uniformity of the applied solid shade is limited only by the uniformity of the orifices in the applicator orifice plate. Additionally, by operating at higher fluid pressures than electrostatic fluid jet applicators, the present invention is significantly more productive than such electrostatic applicators.

International Classification:

C09B 6500

US Classification:

8 30

Abstract:

Carboxy substituted aromatic chromophores are reactively linked to fibers containing alcoholic hydroxyl groups, amino groups or thiol groups, such as cellulosic fibers, with the linkage produced in the presence of a cyanamide compound, such as cyanamide or dicyandiamide.

International Classification:

G01D 1518
B05C 1100
B11J 1524

US Classification:

346 11

Abstract:

Fluid jet printing apparatus having a fluid jet printhead and a pair of substrate positioning rolls for moving the substrate between a position below the printhead for printing on the substrate and a position removed from the printhead enabling access to the printhead. Two or more printing stations, each having a fluid jet printhead and substrate positioning rolls, are serially aligned in the direction of movement of the substrate to print different fluids on the substrate. Idler rolls are arranged to effect printing on opposite sides of the substrate at the respective printing stations. The direction of travel of the substrate past the printhead may be in a direction to first pass the catcher and then the droplet streams thereby minimizing or eliminating the tendency of particles to enter the region of the electrodes.

International Classification:

G01D 1518
B23P 1500

US Classification:

346 75

Abstract:

An orifice plate mounting assembly includes a manifold having an interior cavity defining an elongated slot and fluid communication therewith and a pair of exterior vertical guide surfaces bracketing a recessed substantially planar surface surrounding the elongated slot. A pair of clamping members each having a clamp body, a clamping arm extending horizontally outwardly from the clamp body and defining substantially planar contact surfaces, and hinge elements are provided to horizontally position the planar contact surface of each clamping arm in planar contact with the respective portion of the planar orifice plate laterally of the linear array of orifices. Suitable securing elements bridge the manifold assembly in each clamp body to cause each planar contact surface to exert a clamping force against the orifice plate so as to, in turn, exert a clamping force between the planar orifice plate and the recessed planar surface. In one embodiment, the orifice plate is mounted by thermally expanding the length thereof to a predetermined amount and then allowing the orifice plate to thermally contract while maintaining its expanded length so that the orifice plate is maintained in tension between its opposing ends. In an alternative embodiment, a tensioning apparatus is used to place the orifice plate under tension prior to its being clamped into position.

Abstract:

A novel class of dyes are disclosed of the formula: ##STR1## where D represents a chromophore and R represents a phosphonic or a phosphoric group. These acid groups serve both as water-solubilizing and as reactive groups to bond the dyes covalently to cellulosic substrates.

Appl. No.:

7/188701

Inventors:

Louis A. Graham - Greensboro NC

Assignee:

Burlington Industries, Inc. - Greensboro NC

International Classification:

G01D 1516

US Classification:

346 11

Abstract:

The fluid jet applicator of the present invention utilizes a piezoelectric crystal to artificially stimulate the fluid supply chamber with coherent acoustic energy to pruposely generate and exploit the acoustic standing waves therein. As a result, although sized droplets will be formed at substantially the same frequency from each orifice, individual droplets will be formed so as to be out of phase with its adjacent neighbors in accordance with the standing acoustic wave pattern. By selecting only a very short print time, e. g. , such that only one or two drops are formed within such a time and by controlling the frequency of such print time, a wide range of aesthetically appealing, unique, random interference of patterns can be created. Patterns closely simulating natural wood grains including knot holes can be readily produced by the present invention. More, the present invention allows patterns to be modified with relative ease and remarkable flexibility.
