The use of a fully-hydrolyzed polyvinyl alcohol modified melamine-formaldehyde resin coating for the print sheet in a decorative laminate eliminates the necessity for an overlay sheet without thereby imparting any deleterious effects to the laminate itself.

An ohmic contact electrode is overlaid with a fritless bicomponent silver or gold composition that is alloyed or soldered so as to provide a continuous layer having low lateral resistance. The overlay is composed of a sintered mixture of metal flakes approximately one-half to one micron in size and of a very fine metal powder whose particle size is between 100-1000 A. The ohmic contact electrode is on an electrical device employing an inorganic substrate of the type having a highly electronegati...

Improved coating compositions are described for the protection of superalloys at elevated temperatures. The coatings are of the MCrAlY type where M is nickel or cobalt and are significantly improved by the addition of from 0.1-7% silicon and 0.1-2% hafnium. Coatings of the invention are preferably applied by plasma spraying and as so applied are found to be substantially more effective than prior art coatings.

A flux for overlay welding, essentially containing by weight 30-70% of CaF.sub.2, 10-30% of Al.sub.2 O.sub.3, 1-15% of CaO, 5-25% of SiO.sub.2 and 5-25% of MgO such that the total amount of CaF.sub.2, Al.sub.2 O.sub.3, CaO, SiO.sub.2 and MgO is greater than 70%, while satisfying the conditions of MgO/(Al.sub.2 O.sub.3 +SiO.sub.2).gtoreq.0.20, MgO/SiO.sub.2 .ltoreq.2.0 and MgO/Al.sub.2 O.sub.3 .ltoreq.2.0.

A keyboard has first and second nested planar members with depressions formed thereon. The upper member is transparent. The lower member may be color coded and carry replaceable key indicia in the depressions. The laminated overlay nested planar members are disposed adjacent to a conventional elastomeric diaphragm switch assembly having an upper layer of shaped protrusions abutting the lower most inner surfaces of the second or lower member depressions. Frame structure of variable form assists i...

A trimmer potentiometer includes an elongate resistive element which is screened over a portion of each end terminal pad. Each end terminal pad extends laterally from the overlay and wiper means is disposed for engagement with the lateral extensions of the end terminal pads to short out the resistive overlay portion and prevent the potentiometer from exhibiting a resistance through the thickness of the resistive element at an overlay portion. BACKGROUND OF THE INVENTION 1. Field of the Invention...

Crack and wear resistant concrete overlays for renovation or patching of deteriorated sections over a substratum can be made by incorporating 4-12 volume percent steel fibers in the concrete overlay and bonding at least a portion of the fibers directly to the substratum.

A fishing lure with a main body as a tapered fluted screw and a metal journal insert for weight and vibration through the longitudinal axis. A shaft runs through the insert to provide line and hook attachment at the ends. A shiny metal overlay is loosely mounted on the shaft on each end of the main body, with the loose fit over one vane surface providing higher vibration and slower rotation due to the fit and off-balance of the lure.

A graphic forms overlay apparatus to be used with non-impact printers requiring the use of a movable light sensitive medium such as laser printers is disclosed. Laser printers use a sweeping laser beam and a movable light sensitive medium to image data from a data processing source for printing. A graphic forms pattern is overlayed on the data imaged on the light sensitive medium for simultaneous printing of the data and pattern. To accomplish this a negative of the pattern is mounted on a hollo...

A border molding strip is placed about the perimeter of an existing window pane. A second pane is then placed upon this border material. A retaining border is then placed to retain the window pane firmly against the border material, thus creating an airtight seal between the existing window pane, the border material and the second window pane. Appropriate adhesive and sealing compounds are applied to insure an airtight seal. Thereafter, the space between the existing window pane and the suppleme...
