The mark obtained by this process is erasable with an appropriate acid or base.

Abstract: A method for manufacturing a keyboard which can be utilized in a keying structure is described. It consists of layering a flat fixed plate with a conductive paint, masking a preformed insulating rubber keyboard, laying the keyboard on the conductive paint surface and thereafter applying pressure to the rubber keyboard to the extent that certain portions of the rubber keyboard are put in contact with the conductive paint.

Abstract: Densified regions are formed in a low integrity dry-formed nonwoven fibrous web by embossing a front surface of the web with spaced-apart raised surfaces of an embossing roll. The web is embossed to the extent that the densified regions will transmit a treating fluid completely through their thickness to the front surface of the web while non-densified or high loft regions will not. Simultaneously with the embossing, treating fluid from a treating fluid conveying surface is applied to a rear surface of the web. The fluid migrates completely through the thickness of the web to the front surface in substantially only the densified regions of the web.The product of this invention is a dry-formed web having a basis weight in the range of about 0.5 oz./yds..sup.2 to about 8.0 oz./yds..sup.2. A surface of the web has an undulate profile including high loft regions and valley regions. The density of the web in the high loft regions is less than about 0.10 gr.

Abstract: Low cost decorative award plaques are provided which use a plastic laminate article capable of being hot stamped with desired lettering or designs. The plaque is made by a process of repeatedly imprinting with different colors and surface effects. The process includes forming and cutting the plastic on a rigid backing, especially one simulating a fine, hardwood panel.

Abstract: Method of formation of lenses at optical fiber ends to increase the coupling efficiency thereof. In a first embodiment, the end of the optical fiber is masked with a substance non-soluble in the etching reagent. The portion of the coating at the very end of the fiber is then removed and the fiber end immersed in an etching reagent. The etching reagent serves to dissolve the uncoated portion of the fiber. By controlling the amount of time that the fiber end is in the reagent, different lens shapes may be formed. In a second embodiment, the fiber end is dipped into a liquid epoxy compound whereby a portion of the epoxy is deposited onto the fiber end. The surface tension of the portion deposited thereon draws the liquid epoxy into the desired lens shape. The epoxy is then hardened to form a permanent lens structure on the fiber end.

Abstract: A method of forming a recording disc having a smooth groove suitable for recording video information from a disc having irregularities along the peaks between adjacent groove convolutions by replicating the grooved disc to produce a negative reproduction of the groove and applying an excess of deformable or removable material such as electron beam sensitive material to the surface of the replicated disc while rotating the disc rapidly only long enough to drive off the excess material and allowing the remaining material to dry, partially filling the groove and providing a continuous coating over the wall and valley portions thereof.

Abstract: A phosphor screen for converting x-rays to light includes a large number of discrete columns of the phosphor material, say doped CsI, with the spaces therebetween preferably filled with a reflective substance, which itself may be phosphor (e.g., Gd.sub.2 O.sub.2 S or La.sub.2 O.sub.2 S). Because of the resulting inhibition of lateral spread of light within the phosphor screen, it may be made thicker than conventional screens while achieving at least as high resolution and contrast, thereby increasing brightness (and thus requiring lower x-ray "doses"). A method for making the screen includes using a patterned substrate and wide-angle vapor deposition (as in a hot-wall evaporator) so as to deposit the phosphor only on the raised portions of the substrate.

Abstract: Mineral or wood fiberboard is provided with a disrupted or embossed decorative surface, painted overall with a paint containing yellow pigment grade ferric oxide pigment, and the high areas contacted with a heated surface at a temperature such that the ferric oxide pigment is heated to drive off the water of hydration and convert it to a red ferric oxide, thus achieving a two-toned decorative painted board product.

Abstract: A novel adhesive material comprising a plastic foam having at least a surface layer of open cells in which the surface layer of cells contains a pressure-sensitive adhesive composition formed by applying the adhesive to the foam, while the foam is maintained under pressure sufficient to cause the cell walls of the surface layer of cells to be exposed and be relatively flat so as to receive the adhesive. Upon the release of pressure, the cellular structure returns to its normal state and does not exhibit a tacky surface but will adhere to itself upon the application of pressure sufficient to expose the adhesive-containing cell walls.

Abstract: The instant invention relates to a method of decorating an extruded plastic strip which is used for ornamental purposes. In the method of the invention, a plastic strip is passed through a pair of rollers which emboss the face thereof to be decorated with a raised design. The entire decorative face is then covered with a release agent from the top surface of the raised design. A coloring material is then applied to the entire decorative surface. Excess coloring and the release agent are thereafter washed, peeled, or otherwise removed from the strip. The design is then highlighted by the coloring material thereupon.

Abstract: A method is disclosed for continuously applying a resinous wear-resistance surface of finish coating to a traveling web substrate which comprises moving the web into a free hanging loop, continuously feeding the liquid resin coating composition into the loop at a rate so as to maintain at least a slight overflow of the composition at the sides of the loop, withdrawing the web upwardly from the loop with a thin coating of the resin applied thereto, and then heating the coated web for drying the coating.

Abstract: Particles of metallic sodium or potassium are placed on a wood substrate which has been pre-heated. When the wood substrate is introduced subsequently into a steam zone the sodium or potassium, as the case may be, reacts exothermally with the water vapor, melts and burns, charring the wood in localized regions. The particles of sodium or potassium are confined by grains of sand which are subsequently brushed away with any loose charcoal to produce a distressed surface to the wood.

Abstract: A method, and a machine for performing the method, for treating wood panels to develop a relief therein, and including subsequent staining, comprising brushing a panel to develop a relief, and then flooding the panel with liquid stain, and after drying, again brushing the panel surface, resulting in a contrasting and attractive panel surface.

Abstract: Impregnating porous material such as sealing materials by introducing a viscous liquid impregnating material under high pressure into the surface of a limited zone of said porous material.

Abstract: A method for preparing coatings, particularly imaged surfaces such as photoresists, printing plates, etc. which includes coating the surface of a substrate with a solid curable composition containing liquid polyene and solid styrene-allyl alcohol copolymer based polythiol components, curing the composition by exposing selected areas thereof to a free radical generating source, e.g. actinic radiation and removing, e.g., by dissolving, the uncured, unexposed areas of the curable composition to bare the underlying substrate. The solid polythiol is a reaction product of a copolymer of styrene-allyl alcohol and a mercaptocarboxylic acid, e.g. .beta.-mercaptopropionic acid.

Abstract: Fused silicide coatings for protecting niobium alloy substrates are modified by providing dispersed nucleation sites in the form of discrete particles in the coating. The discrete particles have a thermal expansion coefficient lower than that of the fused silicide material. This alters the microstructure and reduces the thermal expansion coefficient of the coating so as to minimize the number of tensile cracks.
