Abstract: A free ink roller ball pen for dispensing low viscosity inks containing pigments that are prone to sedimentation. The instrument contains an ink reservoir chamber, a nib chamber provided with a roller ball socket assembly, a pressure equalization overflow chamber for the low viscosity ink, and a special agitation system for the ink reservoir and nib chamber. The agitation system comprises a weight, with a cross section smaller than the interior of the nib chamber, connected to a wire having a diameter smaller than the back inner diameter of the ball socket assembly. The length of the weight and its confinement are selected to provide for a predetermined stroke, on shaking the pen, that sweeps out the internal space of the nib and also the back of the roller ball assembly, to re-disperse any pigment that has precipitated.

Abstract: An improved product for transferring an inkjet printed graphics to a receiving surface comprising in combination (1) a water-absorbing porous back sheet (2) a water-soluble resin coating applied to the backing sheet, (3) a waterproof film forming resin coating, and (4) a waterproof inkjet receptive coating. The combination of the foregoing results in a high quality printing and easy transfer to a receiving surface after soaking in water.

Abstract: The problems of applying ink jet inks to various known coating surfaces so as to overcome smearing, poor resolution and attack by water etc., is overcome by the use of the new ink jet receptive media. The media comprises in combination: (1) a waterproof ink jet receptive coating, (2) a primer coating, (3) a non-porous substrate, (4) a pressure sensitive adhesive coating, (5) a silicone coating and (6) a backer layer. The receptive coating comprises the combination of: (1) binder, (2) charge control agent, (3) cross-linking agent, (4) adhesion enhancing agent and (5) dispersant. The absorption of the ink jet ink to the substrate is maximized, thus attracting and fixing the ink and providing a waterproofing effect.

Abstract: A flexible printed circuit, sometimes referred to as a flexible membrane circuit, is screen printed onto one surface of a tightly woven polyester or nylon taffeta fabric. The opposite side of the fabric is coated with a long life pressure sensitive adhesive, protected until use by a suitable release sheet, or coated with a long life heat activated adhesive also protected with a suitable release sheet. The adhesive side of the fabric is applied to the underside of upholstery fabric, for example, the underside of an automobile seat. This provides an economical and functionally effective means of providing complex circuitry for sensing the presence of a person on the seat and/or detecting the weight of such person, etc. Significant savings are realized over conventional circuit-forming techniques.

Abstract: Conventional methods of manufacture of transfer decalcomanias utilizing traditional solvent evaporative ink and adhesive technology are replaced by the present process utilizing ultraviolet (U.V.) cure inks and adhesive technology to produce a better product in a simpler, less costly manufacturing operation.

Abstract: An electrically functional adhesive transfer for use in the manufacture and/or the design of flexible membrane circuits. Electrical circuit elements, instead of being printed directly upon polyester film substrates, are printed upon a carrier sheet. A pressure sensitive adhesive is applied over the exposed surfaces of the printed circuit pattern on the carrier sheet and covered by a release paper. The circuit later is applied to any desired substrate by peeling away the release paper and mounting the circuit by means of the pressure sensitive adhesive. The carrier sheet typically is peeled away after the circuit is adhesively bonded to the substrate. The carrier sheet desirably is transparent or translucent in order to facilitate visual alignment of the circuit pattern with the substrate to which it is being bonded.

Abstract: A process for a production basis relief decorating of ceramic articles. In place of conventional, manual application of relief features, the process provides for a special technique for screen printing of relief features onto the surface of a transfer decal sheet, typically a decal sheet that has previously been printed with a conventional, two-dimensional primary design. The new process includes a screen printing stencil of unusual thickness, at least 0.015" and up to as much as 0.125", characterized by having unrestricted non-convergent through openings. Ceramic inks are formulated to heavy viscosity, having a characteristic comparable to peanut butter, with a viscosity in excess of one million cps. The ink is flow resistant in character, and is forced through the stencil openings by a slow-moving squeegee. The squeegee action is such as to provide increased dwell time of the ink with the surface of the transfer decal paper, before lifting of the stencil.

Abstract: A transfer sheet for applying images to glass, plexiglass and the like to simulate the look of an etched surface is prepared by a three-step screen printing process wherein a polystyrene or release coated paper base is first coated with nitrocellulose and then heated. Thereafter a further coat comprising a combination of nitrocellulose, a silica flattening agent and mica/silica is applied followed by further heating. A screen printable solvent based adhesive suitable for polystyrene or paper is then applied, then heated and, thereafter a slip sheet applied to the adhesive side to permit stacking.
