Abstract: ABSTRACT        Process for Production of Oxidation-Resistant Hydrocarbon Oil Composition, and Oxidation-Resistant Composition made thereby An oxidation-resistant hydrocarbon oil composition is made by catalytically hydrogen-refining under relatively severe conditions a hydrocarbon oil basestock boiling in the lube oil boiling range and separately catalytically hydrogen-refining under relatively mild conditions a hydrocarbon fraction boiling in the lube oil range and having an aniline point   at least     60°C and a sulfur content of at least 2.0 wt %.  The resulting severely-refined basestock has a sulfur content not greater than 0.10 wt % and the resulting mildly-refined fraction has a sulfur content of at least 1.0 wt %, and the desired oxidation resistant composition is a blend comprising 85 to 99.9 wt % of the former and 15 to 0.1 wt % of the latter.

Abstract: Abstract of the Invention A plasma reactor includes a series of parallel disposed electrodes carried in a vacuum vessel chamber. The series of electrodes is adapted to have alternate polarities.  Supporting brackets are provided for positioning workpieces, such as multilayer printed circuit boards, parallel to and between electrodes of alternate polarities.  The supporting brackets are electrically isolated from the electrodes.  Furthermore, a uniform gas flow is directed across the surfaces of the workpieces upon their being subjected to a gas discharge plasma, by providing the plasma reactor with a parabolically-shaped door defining a parabolic surface within  the vacuum vessel chamber, as well as vertically disposed baffle plates and at least three radial gas inlets located equidistantly about said chamber. The radial gas inlets have discharge ends directed at the parabolic surface of the door and are located between the baffle plates and the parabolic door surface.  Parallel arrangement of electrodes, as well as the elements utilized in directing a uniform gas flow, provide uniform conditioning of workpieces positioned within the gas discharge plasma of the plasma reactor.

Abstract: HIGH-SELECTIVITY PLASMA-ASSISTED   ETCHING OF RESIST-MASKED LAYER            Abstract of the Disclosure In a VLSI device fabrication process, erosion of a patterned resist layer  during dry etching of an underlying layer can significantly limit the high-resolution patterning capabilities of the process.  As described herein, a protective polymer layer is formed and maintained only on the resist material while the underlying layer is being etched.  High etch selectivities are thereby achieved.  As a consequence, very thin resist layers can be utilized in the fabrication process and very-high-resolution patterning for VLSI devices is thereby made feasible.

Abstract: : A pattern generator locates a workpiece to be machined into a desired pattern shape in a vacuum. This workpiece is irradiated with a laser beam condensed to a fine point. The beam is scanned to depict the desired pattern shape, whereby the workpiece is directly machined in conformity therewith. Used as a workpiece is a shading film, e.g., chromium film deposited on a transparent glass substrate. By irradiating it in a vacuum, the irradiated parts of the film are vaporized to fabricate a shading mask pattern of good quality. The process is faster and of higher precision than prior art methods.

Abstract: Abstract of the Disclosure A door-casing element comprises an elongated inner metallic profile, an elongated outer metallic profile parallel to and spaced outwardly from the inner profile, an elongated thermally relatively nonconductive connector between and engaging both of the profiles, and ratchet formations securing the profiles in spaced-apart relationship to the connector.  The inner and outer profiles are spaced so it is possible to form them of aluminum, which can be made with an attractive anodized finish and which can be used in outdoors applications without danger of rust.  The thermally nonconductive connector, which can be made of rigid and fire-resistant gypsum fibers, will not transmit heat effectively between the two profiles so that the resultant casing can easily be of high firecode rating.

Abstract: ABSTRACT OF THE DISCLOSURE       A new tent construction employs four first wall-forming triangular shaped panels and four second wall-and-roof  forming trapezoidal panels seamed together.  Thus, the first panels are disposed with their apices uppermost, each panel being folded about a longitudinal line constituting the respective wall corner.          Each second panel comprises a wall triangular portion disposed with its apex downwards, and a roof triangular portion disposed with its apex upwards and inwards, the junction of these two triangular portions constituting the wall horizontal upper edge or eave.         Thus, the tent corners and eaves are formed by folds and not by seams, and the seams are only in flat panels resulting in a strong construction.  If made in panels of complementary colours an attractive appearance is also achieved.

Abstract: Abstract The invention relates to a method and apparatus for reeling a web of material onto a core by glueing the leading end of the web of material to the core and by rotating the core until the roll is of the desired thick-ness, by cutting off the web of material and by attaching the trailing end of the cut-off web of material to the roll.  The method uses a core base onto which so many layers of the web of material are glued that the thick-ness, and thereby the strength, of the thus formed core is sufficient for reeling and for the further handling of the roll.            In the apparatus according to the invention, a web of material (2) coming from a slitting machine (4), a sheet cutter or an unreeling frame is reeled onto a core (10),the apparatus having members (9) supporting and rotating the roll (11). As seen in the travel direction of the web of material, in front of the members (9) supporting and rotating the roll (11), there are members (8) which extend across the web of material (2) and are aimed at least at that side of the web of material which in the roll (11) faces inwards, i.e. towards the core (10), for applying a fluid substance, such as glue, water, color and/or various additives to the web of material being reeled.       The invention also relates to a roll of a web of material, around which there is a wrapping composed of two layers of the web of material, glued to each other, and to a method of forming such a wrapping during the reeling of the web of material.
