Abstract: A ceramic multi-layer capacitor which uses specifically formulated electrode inks comprising a mixture of thermoplastic vehicles in combination with finely divided metal powders. The resultant thermoplastic electrode ink can be screen printed onto dielectric ware and immediately laminated, without a drying step. Multi-layer designs may be 50 or more layers wherein the thermoplastic components volatize at an appropriate time/temperature schedule to prevent slumping or delamination and to be chemically compatible with the organic binder components in the dielectric ware.

Abstract: A composite film structure which is useful as a non-brittle, impact-resistant, exceptionally durable, window pane in greenhouses and similar structures, or as storm windows, solar collector covers, etc., comprises an oriented polycarbonate support film laminated to a weather-resistant oriented film of polymethylmethacrylate.

Abstract: A hermetically sealed multiple glazing unit comprises at least one film located between spaced parallel glass panes which are attached to spacing and sealing means constituted by frame portions. The films are attached to the outer frame portions and are stretched when these frame portions are pressed against an intermediate frame portion, by virtue of the profiled confronting surfaces on the frame portions. In another embodiment of the present invention, the multiple glazing unit is not hermetically sealed, and the space between the outer pane and the outermost film is vented through a filter. A silicone coating may be applied to the inner surfaces of the panes and/or to the films to inhibit condensation onto the light-transmitting surfaces. An ultraviolet radiation blocking layer can be provided to protect the film from degradation.

Abstract: A multiple layer of plastic films is laminated in tape form in combination with a layer of aluminum foil so as to enclose the aluminum in a protective layer of plastic, the remaining layers being chosen to provide dielectric and moisture protection for the cable, and incorporating a greater width of plastic combinations than aluminum, such extra width being optionally folded over upon the section containing the aluminum, to provide contiguous faces having thermoplastic properties which will be sealed by the heat of extrusion of the cable jacket during the manufacturing process.

Abstract: A multilayer, metal/organic polymer composite exhibiting excellent resistance to delamination after thermoforming is provided by metallizing a substrate layer of thermoplastic organic polymer such as polystyrene or polycarbonate film and bonding the exposed metal surface to a structural plastic with a soft adhesive layer. Subsequently, the multilayer composite or at least a portion thereof can be shaped into an article which may be structurally reinforced by casting an elastomeric or rigid foamed polymer such as polyurethane foam into a cavity defined by the composite. The multilayer composites are useful in the manufacture of reflective and decorative parts for automobiles and other vehicles of transportation, as well as high barrier packages for foods and electroconductive elements.

Abstract: A process, and the article produced thereby, for providing a uniformly and tenaciously adhered abrasion resistant and chemical resistant non-opaque coating on polycarbonate articles. The process comprises priming the surface of the polycarbonate article with an adhesion promoting thermoplastic acrylic polymer by forming a thin film of said thermoplastic acrylic polymer on the surface of the polycarbonate article, applying a silica filled organopolysiloxane coating composition onto the primed polycarbonate article, and thereafter curing the silica filled organopolysiloxane to form a hard, abrasion and chemical solvent resistant top coat which is tenaciously adhered to the polycarbonate article. The non-opaque coated polycarbonate article produced by this process comprises a polycarbonate substrate having (i) a primer layer comprised of a thermoplastic acrylic polymer, and (ii) a thermoset silica filled organopolysiloxane top coat.

Abstract: Metal working operations, especially drawing, are facilitated by applying to the metal a composition which provides lubricity thereto, which melts at about 30.degree.-150.degree. C., and which comprises principally a polymer of a monoepoxide or monoepisulfide containing from about 8 to about 25 carbon atoms. The composition may be applied in liquid form and solidifies on cooling to ambient and normal storage temperatures. Prior to application, the composition is preferably heated to a temperature higher than its melting temperature for ease of flow and uniform dispersion thereof onto the metal.

Abstract: A heat-recoverable wrap-around device made from heat-shrinkable sheet material is provided with mechanical retaining means which co-operate with opposed edge regions of the sheet material so that after recovery about a substrate such as an electrical cable, the device lies substantially flush with the substrate without protuberances. The mechanical retaining means is preferably a buckle which is shaped to conform with the substrate and in which the sheet material is held by frictional forces.

Abstract: Cellulose materials such as paper and card stocks are provided in a generally transparent or so-called transparentized form while substantially maintaining the initial strength and stiffness of the pretreated stock. A generally opaque stock is treated with a solventless resin system which is cured by actinic radiation in order to thereby transparentize the stock without subjecting it to lengthy and relatively severe wetting conditions.

Abstract: A composition is disclosed in which a solid isocyanate compound such as toluene-diisocyanate dimer is dispersed within a polyurethane based on a hydroxy-terminated organic compound, preferably polybutadiene. The composition can be fully cured on a surface and yet provides an excess of stable material, i.e. dormant isocyanate containing groups, which are reactive on demand to strengthen interfaces with adjacent layers containing available hydroxyl groups, such as a layer of solid polyurethane-based propellant, without the need for intermediate reactive coatings.

Abstract: A mirror construction and method wherein shatter resistant optical quality first surface mirrors may be inexpensively fabricated. A styrene sheet is press polished and the polished surface is coated with a reflective layer. The press polished, reflectively coated styrene sheet may be subjected to further processing steps in order to produce a highly rigid and flat mirror. A surface of the styrene sheet is scored along a straight line to a depth that does not penetrate the front mirrored surface, but rather leaves a relatively thin region along the scored line having a minimal extent in the plane of the sheet. The styrene sheet is then folded, bringing portions on either side of the scored line towards each other and partially splitting the thin region. A membrane remains along the scored line to form a semi-flexing hinge. The ability of the membrane to withstand cracking can be improved somewhat by carrying out the folding step at a temperature generally greater than approximately 20.degree. C.
