Abstract: An apparatus for spin coating surfaces with liquid polymer comprises a spin coating chamber having a rotatable chuck for supporting an object to be coated. A distributor introduces gases into the chamber. A solvent vapor and carrier gas supply provides a carrier gas having a controlled level of solvent vapor therein within the range of from 0 to saturation concentrations of solvent vapor. A solvent vapor sensor is positioned with respect to the coating chamber to produce signals which correspond to the concentration of solvent vapor in the coating chamber. A control means is connected to the solvent vapor concentration sensor and to the solvent vapor and carrier gas supply means for controlling the level of solvent concentration in the carrier gas supplied by the solvent vapor and carrier gas supply means. The solvent vapor level can be obtained by controlled mixing of solvent-bearing and solvent-free gas streams, or by injection of solvent into a gas stream by means of an atomizer, for example.

Abstract: A flattened tubular knitted wire mesh is passed through a bath of a slurry comprising a vermiculite binder and a high temperature lubricant powder with optional metal fibers suspended in water to form an impregnated moving slurry filled web. The slurry filled web is passed between metering bars to remove excess slurry to reduce the web to the desired thickness and then dried in an oven at a temperature in the range of about 200-400.degree. F. The web is conveyed at about 5 feet/minute and forms a continuous sheet of flexible preform with a dried filler which is wound on a take up roller driven by a motor via a controller which also operates the web drying oven. The preform is then formed into discrete preforms for article manufacture such as seals and the like by conventional die compression.

Abstract: A method for forming a supported thin layer of non-evaporable getter (NEG) material and a getter device formed thereby are provided. A suspension comprised of non-evaporable getter (NEG) material particles in a dispersing medium is prepared. The NEG material particles in the suspension have a particle size not greater than about 150 .mu.m.

Abstract: A spin coater drying cover is disclosed having unique properties and construction to enable accurate control of the drying process of an optically active lamina of a Nitrocellulose Dye Polymer solution on a Polycarbonate disc substrate. The cover is configured with an orientation platform allowing micro adjustment of the angle and distance of a porous gas filter disc of the cover in relation to the optically active layer. The filter, essentially parallel and concentric to the disc substrate, can be varied from a flat, concave or convex camber to cause gas flow over the disc substrate to be such that a variable linear ramp of the optically active lamina can be achieved, with a thicker layer at the periphery than at the center of the disc. This enables deeper data pits to be formed at the difficult to mold outer disc periphery, thus increasing yield in a disc mastering process.

Abstract: A dispense nozzle (10), having a narrow oblong orifice (14), is positioned over and near the surface of the substrate (22), close to the edge of the substrate. While the substrate is rotating, the nozzle dispenses fluid through the narrow oblong orifice onto the substrate surface, starting from near the outer edge (24) moving toward the substrate's rotational center (26). The narrow oblong orifice may have lips of unequal size to help direct fluid flow. A controlled rate of acceleration is maintained for the rate of translation of the nozzle across the substrate surface. Once the nozzle approaches the substrate's rotational center, the nozzle is raised to a higher height above the surface of the substrate while continuing to dispense fluid. Then the dispense stream of fluid is terminated, and the substrate is rapidly accelerated to a predetermined spin speed to evenly distribute the fluid over the surface of the substrate to a uniform film of desired thickness.

Abstract: In order to prevent or at least render difficult the copying of colored printed security papers, for example banknotes, the printing inks used for printing are so formulated that copies made using customary color copiers produce a markedly different color impression and can therefore easily be identified as being forgeries. This is achieved by using for the formulation of the printing inks dyes (pigments) that are as different as possible from the dyes (toners) customarily used in conventional color copiers. The choice of the dyes for the formulation of the printing inks is especially such that there is the greatest possible degree of metamerism between the printing ink in question and the match of the relevant master color using the dyes of the color copier. Preferably non-amorphous or anisotropic black dyes and effect dyes, especially fluorescent effect dyes, are co-used for the formulation of the printing inks.
