Abstract: A protective case is disclosed that has a preventative agent disposed therein for safely housing an object or material with an adverse characteristic such as high heat or volatility is disclosed. The preventative agent normalizes the adverse characteristic from the object or material before that characteristic can reach the outside environment.

Abstract: A means for determining the concentration of a hydrogen-rich fuel in a fuel solution within the anode reservoir of a fuel cell. The fuel concentration is determined using a float responsive to fuel solution density. As fuel is consumed, the fuel concentration decreases. As the fuel concentration decreases, the density of the fuel solution increases, causing the float to rise. A window may be included in the anode reservoir or in an attached float chamber to facilitate inspection of the position of the float. A fuel scale may be included to facilitate fuel concentration determination based on the position of the float within the fuel solution. Additionally, a valve responsive to float position may act to control fuel delivery.

Abstract: A means for determining the concentration of a hydrogen-rich fuel in a fuel solution within the anode reservoir of a fuel cell. The fuel concentration is determined using a dye mixture responsive to fuel concentration within a fuel solution. As fuel is consumed, the fuel concentration decreases. As the fuel concentration decreases, the dye changes color. The resulting color changes occur within the anode reservoir of the fuel cell, or within a dye chamber in fluid contact with the anode reservoir, and are made visible by a window. A color strip and fuel scale may be included to facilitate fuel concentration determination based on the color of the fuel solution. Additionally, a valve responsive to dye color may act to control fuel delivery.

Abstract: Production of a permanent ink-jet image with a fusible, wettable, toner and ink-jetted ink.

Abstract: An integrated system for individually labeling a recording medium at the time that digital information is recorded thereon, by recording write data with a digital recorder on the read/write surface of the CD/DVD and recording image data by inducing visible color change with a laser in laser sensitive materials on the opposite surface of the CD/DVD.

Abstract: The present invention provides a container which has multiple protective characteristics integrated into the container. The protective container for containing a material and protecting against adverse exposure to the material includes a durable outer casing; an inner casing in direct contact with the material, which is less durable than the outer casing; and at lease one layer of a preventative agent disposed between the inner and outer casings for disabling the material upon failure of the inner casing. The protective container provides improved active control to prevent accidental adverse exposure to the container contents.

Abstract: The invention relates to an improved system for inkjet printing which results in images with increased permanence as measured by transfer of color from the image when the image is subjected to mechanical and/or chemical abrasion. The invention provides a fusible material that may be combined with any or all of the color inks used to create the image, or it may be used as a colorless fluid applied pre- or post-printing. The permanence of images produced by the system are comparable to those produced by electrophotography.

Abstract: Production of a permanent ink-jet image with a fusible, wettable, toner and ink-jetted ink.

Abstract: Production of a permanent ink-jet image with a fusible, wettable, colorant-containing toner and ink-jetted clear fluid.

Abstract: The present invention relates to ink-jet inks in combination with a clear, dry toner to produce a permanent ink-jet image. In particular, this invention relates to an ink system that utilizes the addition of specific toner/developers, typically found in the laser printer field, with aqueous based in-jet inks. These dual systems produce a permanent image that is resistant to image degradation factors such as mechanical abrasion, light, water, and solvents such as the ones used in highlighter markers.

Abstract: The invention relates to an improved system for inkjet printing which results in images with increased permanence as measured by transfer of color from the image when the image is subjected to mechanical and/or chemical abrasion. The invention provides a fusible material that may be combined with any or all of the color inks used to create the image, or it may be used as a colorless fluid applied pre- or post-printing. The permanence of images produced by the system are comparable to those produced by electrophotography. The invention also relates to a printing apparatus that contains a means for fusing the image using heat applied after printed substrate is ejected from the printer. Methods for utilizing these improvements and examples of them are described.

Abstract: An inkset suitable for inkjet printing is presented which contains a polymer system which reacts with chitosan to produce a gel precipitate on a substrate. The precipitant of this invention is created by the interaction of the chitosan in one fluid, such as an ink, and a reactive fluid in another pen, typically the 5th pen. The gel form a protective film on the medium substrate and provides permanence benefits, such as increased drytime, smearfastness, smudgefastness, and waterfastness.

Abstract: The invention relates to an improved systems and methods for ink-jet printing which result in images with increased permanence as measured by transfer of black or color from the image when the image is subjected to mechanical and/or chemical abrasion. The invention provides a fusible composition that may be combined with any or all of the black or color inks used to create the image, or it may be used as a colorless fluid applied during pre-, post-, or simultaneous ink-jet ink printing, with the proviso that both the ink-jet ink and the fusible composition be mixed in a liquid form for fusion. The permanence of images produced by the system can be comparable to those produced by electrophotography.

Abstract: The present invention relates to surfactants that help improve image quality attributes, in particular chroma (i.e., color saturation), and ink-jet inks formulated with the same to produce inks exhibiting more than one of the desirable properties such as improved chroma, bleed control, edge acuity, and surface retention, thereby improving image quality. More specifically, the invention relates to surfactants that form relatively large aggregated structures (micelles) of geometry other than spherical, hence fourth referred to as lamellae forming surfactants.

Abstract: If the particle size of pigments in ink-jet inks is reduced below 500 nm, then the ink compositions achieved extraordinary stability; that is, there is no visible sediment formed after three weeks at ambient temperature and there is no sediment formed after heating to 70.degree. C. for 10 min followed by cooling to 0.degree. C. for 10 min. No dispersant is necessary, and the pigment particles having such a defined size may be incorporated into microemulsions, using a suitable oil (water-immiscible organic compound), at least one amphiphile, and water.

Abstract: The ink of the invention comprises a vehicle and a colorant. The colorant is a pigment that has been treated to reduce nozzle outs in the inkjet printers. The performance of these pigments is improved by forcing the pigment through an acute pressure valve process wherein the pigment is homogenized to a size of about 0.1 .mu.m.

Abstract: Ink compositions comprising liposome vesicles with water-insoluble dye or pigment contained therein are described. The vesicles may be unilamellar or multilamellar and may be made using standard liposome forming materials such as phospholipids or tocopherol succinate. When the present invention is used with electronic printing systems such as an ink jet printer, the generated images are sharp, fast drying, waterfast, lightfast, and of high optical density.
