  • Patent number: 4380566
    Abstract: A technique is disclosed for protecting integrated circuits from alpha particles. A central portion of a radiation resistant insulating substrate upon which electrically conductive leads are disposed is positioned in proximity to the integrated circuit. When the leads are electrically connected to the integrated circuit, the central portion of the substrate is allowed to remain over the integrated circuit to protect the integrated circuit.

  • Patent number: 4379797
    Abstract: An automatically expanding pop-up decoration for use in gift-wrapping a package is capable of assuming a compact folded orientation suitable for storage in a limited area, yet expands automatically upon application to a package so as to create a substantially upstanding portion. The decoration comprises an ornament having a pair of opposed end members and an expansible structure pivotally joining the end members together. It further comprises an elastic cord operatively engaging the opposed ornament end members so that application of the cord about a package so as to tension the cord automatically causes the ornament end members to pivot into a substantially edge-to-edge relationship with the expansible structure standing substantially upright from the package.

  • Patent number: 4377613
    Abstract: This disclosure describes transparent glass window structures of the type bearing a coating of infra-red reflective material which is advantageously less than about 0.85 microns in thickness and wherein the observance of iridescence resulting from such a reflective coating is markedly reduced by provision of a very thin coating system beneath said infra-red reflective coating. The thin coating system forms means to reflect and refract light to interfere with the observation of iridescence. A particular advantage of the invention is the ability of the thin coating system to be coated in a fraction of time presently required to coat anti-iridescent interlayers of the prior art.

The decoration comprises an ornament having a pair of opposed end members and an expansible structure pivotally joining the end members together. It further comprises an elastic cord having the opposite ends thereof secured to the opposed ornament end members so that application of the cord about a package so as to tension the cord ends automatically causes the ornament end members to pivot into a substantially edge-to-edge relationship with the expansible structure standing substantially upright from the package.

  • Patent number: 4374183
    Abstract: A low cost coating protects metallic base system substrates from high temperatures, high gas velocity ovidation, thermal fatigue and hot corrosion. The coating is particularly useful for protecting vanes and blades in aircraft and land based gas turbine engines.A lacquer slurry comprising cellulose nitrate containing high purity silicon powder is sprayed onto the superalloy substrates. The silicon layer is then aluminized to complete the coating.The Si-Al coating is less costly to produce than advanced aluminides and protects the substrate from oxidation and thermal fatigue for a much longer period of time than the conventional aluminide coatings. While more expensive Pt-Al coatings and physical vapor desposited MCrAlY coatings may last longer or provide equal protection on certain substrates, the Si-Al coating exceeded the performance of both types of coatings on certain superalloys in high gas velocity oxidation and thermal fatigue.

  • Patent number: 4371574
    Abstract: The present application relates to enclosure members consisting essentially of solid, non-aromatic polymers that have a linear carbon to carbon backbone structure and having a plurality of free hydrogen atoms attached to the carbon atoms with a permeability to wet solvents and fuels of less than 1/50, optionally less than 1/200 of the permeability of untreated enclosure members having a thickness of 1 mm. Said low permeability is due to the presence of a coating on at least the inner surface of said enclosure members, having a portion of the hydrogen atoms replaced by sulphonic acid or sulphonate groups, consisting of a cured thin layer (of at least 2 .mu.m) of condensation products of formaldehyde and melamine of formaldehyde and urea. Evidently the application relates also to a method of preparing said enclosure members.

  • Patent number: 4371422
    Abstract: Disclosed is the continuous processing of flat workpieces such as printed circuit boards which are suspended by a hanger conveyorized for continuous horizontal transport. More specifically, the conveyorizing passes the workpieces through a plurality of chambers having slotted-end members, one such chamber spraying to remove the photoresist, and another such chamber spraying etching solution to remove the copper cladding. Each station has a slotted cover, and the conveyor suspends a plurality of workpiece holders, each of the holders being joined by chain links of an inert material which overlie the slot in the covers for the chambers. The photoresist chamber is provided with a continuous filter for continuously removing and filtering the sludge, thereby reducing the tendency of the removal solution to dilute and become ineffective. All of the chambers are modularized, and the system is compatible with continuous processing for the plating of the printed circuit boards.
