International Classification:

B41J 2/01

US Classification:

347102000, 347093000

Abstract:

This invention relates to fast-drying RF inkjet composition and apparatus for inkjet printing RF inkjet compositions. The compositions and apparatus are useful for inkjet printing onto a variety of media including both porous and non-porous substrates. The RF inkjet composition desirably includes RF susceptors combined with polar carriers which may be activated by RF energy to generate heat within the RF inkjet composition, resulting in enhanced evaporative drying.

International Classification:

G03G 910
B32B 2502
B32B 2740

US Classification:

430108

Abstract:

Electrophotographic developer compositions containing carrier, toner and special purpose additives such as flow promoters, dry lubricants and the like are prepared by coating carrier particles with a coating selected so that the triboelectric relationship between the surface of the carrier and the surface of the additive is substantially zero.

Assignee:

Dactek International, Inc. - Van Nuys CA

International Classification:

A61B 510

US Classification:

427 1

Abstract:

Fingerprints images are formed by applying the distal portion 29 of a finger 32 to a porous pad 10 impregnated with a solution of marking compound. The finger portion may be prewetted or cleaned with cloth 30 impregnated with detergent solution. The finger 32 is then applied to a square 36 of a fingerprint card 38 impregnated with an aqueous solution of polyhydroxy developer such as 8-hydroxy-quinoline and propyl gallate containing a high molecular weight dibasic acid such as azelaic acid. A fingerprint image 40 immediately develops. Traces of the image can be removed with a cleaning solution impregnated cloth 42.

International Classification:

G03G 908
B28B 1106

US Classification:

430137

Abstract:

A free-flowing, non-spherical, fragmentary, toner particle is prepared by blending a mixture of thermoplastic resins with magnetic iron oxide. The dispersion is processed to a fine powder and dry blended with conductive carbon black which is anchored onto the surface of the particle by warm air or gas.

Louis B. Meadows - Valencia CA
Arthur S. Diamond - Ventura CA

Assignee:

Dactek International, Inc. - Van Nuys CA

International Classification:

B41K 100

US Classification:

118 315

Abstract:

A compact fingerprinting system includes an applicator comprising a sealed packet (13) containing a porous pad (12) impregnated with a solution of water-soluble, color-forming, marking compound, such as iron chloride having a controlled, optimum water content. A print of a body part, such as a finger, is formed by opening the packet (60) and wiping the distal portion of a finger (76) on the pad (62), such as a folded towelette to form a non-visible, latent image pattern. The pattern is transferred to a card (40) which can contain an area (44) impregnated with developer for the marking compound. The developer reacts with the pattern to form a dark, distinct, permanent image (84). The card (40) and packet (13) can be enclosed in an envelope (64) to form a low profile, lightweight, mailable, self-administered fingerprinting system.

International Classification:

US Classification:

128630

Abstract:

Method and apparatus for recording sweat gland activity which provides a pictorial representation thereof by physical contact of an iodide treated skin area with a dry sensitized substrate. In one preferred embodiment, the sensitized substrate comprises a sheet material which has been coated with an aqueous solution containing from 1 to 10 percent by weight of starch and from 2 to 10 percent by weight of a suitable oxidizing agent such as potassium persulfate. Alternately, the dry sensitized substrate comprises a starch-oxidizing agent mixture which has been impregnated into an absorbent base layer. With slight modification of the foregoing embodiment, the present invention also provides a method and apparatus for obtaining inkless fingerprints by forming a sensitized coating in situ on a substrate. For fingerprinting purposes, the sensitized coating is preferably formed from a quick drying starch-oxidizing agent solution including alcohol as a solvent. Accordingly, an aqueous iodide solution is applied to the skin area, and the treated skin area is subsequently contacted with the dry sensitized coating to produce the fingerprint.
