A printing ink comprises a clear, transparent, polymeric carrier material and uniform, colloidal size charged color particles evenly dispersed therein. The carrier and the particles are adhesively bonded to one another so as to form a matrix which can collectively respond to an externally imposed electrostatic field to promote co-movement of a "bite" of ink to an imaging medium without change of the bulk particle/carrier ratio. During the printing process, the ink is melted and exposed to electrostatically charged latent image areas on a heated image cylinder, resulting in the transfer of the ink thereto in proportion to the electrostatic field strength. The ink exhibits a relatively sharp liquid-to-solid transition, thereby enabling rapid ink solidification and complete transfer from the imaging medium to the relatively cool printing substrate. Also disclosed is a printing method and apparatus that facilitate continuous, variable and on-demand color printing in conjunction with the ink. Use of essentially monodispersed, color-coated, colloidal size, spherical particles in the ink results in excellent color purity and chromaticity range.

A method of making a gas-impermeable, chemically inert container wall structure comprising the steps of providing a base layer of an organic polymeric material; conducting a pair of reactive gases to the surface of the base layer preferably by pulsed gas injection; heating the gases preferably by microwave energy pulses sufficiently to create a plasma which causes chemical reaction of the gases to form an inorganic vapor compound which becomes deposited on the surface, and continuing the conducting and heating until the compound vapor deposit on the surface forms a gas-impermeable, chemically inert barrier layer of the desired thickness on the surface. Various wall structures and apparatus for making them are also disclosed.

A method of electrophotographic color reproduction by forming sequentially superimposed toner images of each color successively on the photoconductive surface of an electrophotographic recording member. The photoconductive surface is charged uniformly by a corona generator to a predetermined charge level. The charged surface is exposed to a first color radiation pattern from a source thereof to form a latent electrostatic charge image on said surface. The resulting latent charge image is toned with one color toner to produce a first toner image. The resulting toner image is dried. Thereafter, a charge is applied uniformly to the same photoconductive surface including those portions thereof carrying the dried first toner image in a manner so that the generated charged ions effectively tunnel through the dry adjacent toner particles defining first toner image to reach the photoconductive surface. The resulting charge potential is uniformly distributed over the entire photoconductor surface, including the toned and untoned areas thereof. Thereafter, the entire charged surface is exposed to a second radiation color pattern from a source thereof, the radiation penetrating the first toner image to produce a second latent electrostatic charge image on said overall surface.

A proofing system incorporates an image member having a dielectric surface and a write head for writing a pattern of electrostatic image dots on the surface. A controller is provided for controlling the write head in response to digital data representing an original document so that the image dots of the pattern may have variable field strengths and form a latent electrostatic image of the document on the surface. The controller also controls the areas of the image dots written on the surface in accordance with the digital data. An inking head presents an electrostatic ink to the surface whereby the surface acquires ink only at the image dots thereon in amounts proportional to the field strengths of the image dots so as to develop the latent image on the surface. A printing substrate is supported and pressed against the image member surface so that the ink is released from the surface to the substrate thereby producing a proof copy of the original document consisting of a pattern of print dots with variable gray scale values and/or sizes so that the system may produce proof copies composed of patterns of dots which emulate the printing structure produced by an offset press or a gravure press.

Radiation-absorptive materials, suitable for fabrication into packages, sheets, inks, paints, decorative surface treatments, lotions, creams, and gels are disclosed. The materials exploit certain optical properties associated with uniform, spherical, nanosize particles to provide complete radiation absorption, over a selected bandwidth, at low concentration. One type of particle exhibits an "absorption edge" at a chosen wavelength, transmitting radiation whose wavelength exceeds the characteristic bandgap wavelength, while effectively absorbing all radiation with wavelengths smaller than that minimum. Another type of particle exhibits "optical resonance," which causes radiation of a characteristic wavelength to interact with the particles so as to produce self-reinforcing internal reflections that strongly enhance the amplitude of the radiation trapped within the particle.

An electrophotographic color proofing apparatus is provided including a copyboard carrying a color separated positive and capable of being positioned into intimate contact with a charged photoconductive coating of an electrophotographic member. The engaged members are exposed to light, discharging the coating in increments to form a latent electrostatic image thereon. The copyboard is withdrawn and the exposed electrophotographic member rotated 180 degrees facing toward a toning assembly consisting of a row of plural toning units, each carrying a different color toner and arranged in line for linear translation below the exposed electrophotographic member with a selected one toning unit thereof being activated to apply a selected color toner to the latent electrostatic image. The toned member again is revolved 180 degrees. A pre-wet transfer medium in the form of print paper stock is engaged with the toned member for transfer of the toned image, preferably by drawing a roller across said member while employing a simultaneous electrical bias.

A latent electrostatic image is formed on an electrophotographic member having a crystalline, stable coating of wholly inorganic photoconductive material which is of the order of 0. 2 to 2 microns thick. This is effected by moving a corona needle energized by a corona power source and a laser beam modulated from digital information together over the photoconductive coating in a progressive manner at high speed. The latent electrostatic image so formed is then developed.

An electrostatic method of making transparencies and apparatus for practicing said method. An endless electrophotographic belt is charged, imaged and toned with a liquid toner suspension. The belt with the toned image is brought into close proximity to a precisely dimensioned gap defined by a transfer roller along with a sheet of transfer material comprising a transparent substrate polyester carrying a thin ohmic layer bonded thereto and a thin overcoat of a compatible resinous material on the ohmic layer and bonded thereto. An electrical bias is applied across the gap between the belt and the overcoated ohmic layer. The toner particles migrate electrophoretically toward the transfer sheet. Subsequent to transfer, heat is applied to the transfer sheet sufficient to soften the overcoating embedding the transferred toner particles of the toner image within the resin. The transfer material is cooled.

Women's high heel shoes and men's shoes are provided with unidirectionally compressible resilient heels and internal cushioning pads that absorb shock forces when the shoes are worn while walking, thereby reducing stress on the wearer's feet and legs and on the shoe heels themselves. The stiffness or compliance of the heels can be selected or adjusted to suit the wishes of the wearer.

A digital positioning system has a carrier in the form of a belt with a work surface and arrays of first and second conductors extending under that surface generally parallel to one another, each second conductor being spaced close to a first conductor to define a narrow gap between them. A voltage source applies a potential difference between the conductors to produce electrostatic fields which can attract and hold a substrate to said carrier work surface. Sensors are provided to enabling the longitudinal and lateral positions of the belt to be monitored to produce control signals to shift work elements operating on selected locations of the substrate at successive work stations to compensate for unwanted movements of the belt.
