International Classification:

G03G 2100

US Classification:

399353

Abstract:

A photoreceptor cleaning brush for an electrostatographic imaging apparatus contains individual fibers provided with a finishing agent that is a water-miscible aliphatic organic compound containing a plurality of alcoholic hydroxy substituents. The finishing agent is selected from the group of compounds having a molecular weight of up to about 250 and polyethylene glycols having a number-average molecular weight of about 1000 to about 200,000. In an electrostatographic imaging apparatus, the photoconductive imaging element includes the described photoreceptor cleaning brush and a photoconductive surface portion that contains a polycarbonate binder resin. The cleaning brush removes toner from the photoconductive surface portion of the element without damaging it.

B41M 3/14

US Classification:

400 76, 101483

Abstract:

A process is disclosed for printing a document such as a negotiable instrument in a first and a second color for increasing the security of the document. A major portion of the document is printed with a first information in a first color from a first printer. A second information is created from at least a portion of the first information for proving a security pattern. The security pattern is printed over a minor portion of the document in the second color from a second printer to increase the security of the document. The process may be used for printing a check in a magnetically readable first color and a non-magnetically readable second color including colors having a color spectrum located outside of the color spectrum range of a conventional color photocopier.

Appl. No.:

12/807907

Inventors:

James Maher - Tampa FL, US
James Walling - Dunedin FL, US
Timothy Armstrong - Riverview FL, US
Sean Maher - Raleigh NC, US

International Classification:

G06K 15/02

US Classification:

358 328

Abstract:

An improved security system is disclosed for material printed on a substrate comprising a primary marking printed on the substrate for conveying information. A secondary marking provides security to the primary marking. The secondary marking may include a variation in optical properties, a variation in magnetic properties or a variation in both in optical properties and magnetic properties of the primary marking. A method is disclosed comprising printing a primary and a secondary marking on a substrate with the primary marking conveying information and with the secondary marking providing security to the primary marking.

US Classification:

435 5

Abstract:

A rapid and direct assay for detecting of a virus having a characteristic enzyme in clinical samples in which (1) the clinical sample is contacted in solution with a substrate for the enzyme which includes a chromogen that is cleaved from the substrate by the enzyme and a precipitating agent that reacts with the liberated chromogen to form a precipitate (2) filtering the solution to concentrate the precipitate and (3) visually observing the concentrated precipitate for the characteristic color of the chromogen.

International Classification:

US Classification:

435 5

Abstract:

A kit for visually detecting the presence of a virus in a direct clinical specimen is provided. The kit employs a rapid and direct assay for visually detecting a virus having a characteristic enzyme in a direct clinical sample without the need for any culturing step, This assay contains the following steps: (1) the clinical sample is contacted in solution with a substrate for the enzyme which includes a chromogen that is cleaved from the substrate by the enzyme and a precipitating agent which reacts with the liberated chromogen to form a precipitate, (2) the precipitate is concentrated, and (3) the concentrated precipitate is visually observed for the characteristic color of the chromogen. The observance of the characteristic color confirms the presence of the virus in the clinical specimen. The kit contains (a) a buffer solution for extraction of the characteristic enzyme from the clinical sample; (b) a substrate for the characteristic enzyme, where the substrate contains a chromogen that is liberated by reaction between the characteristic enzyme and the substrate, if the characteristic enzyme is present in the clinical sample; (c) a precipitating agent which reacts with the liberated chromogen in the buffer solution to produce a colored precipitate if the characteristic enzyme is present in the clinical sample; and (d) a device for concentrating the colored precipitate sufficiently to provide a distinct, visibly detectable spot of the colored precipitate if the characteristic enzyme is present in the clinical sample.
