  • Patent number: 9140362
    Abstract: The present invention relates generally to a composite plate produced by an alternating stack of (n+1) flexible graphite foils and (n) perforated metal reinforcing foils with spurs (where n?2). The thicknesses of the flexible graphite foils used are preferably such that any 2 mm slice of thickness of the composite plate comprises at least 3 layers of flexible graphite, and has a graphite density per unit area of at least 2.34 kg/m2. For each perforated metal reinforcing foil, the spurs present on the foil generally have a height in relation to the surface of that foil that does not exceed about 1.3 times the thickness of the thinnest of the flexible graphite layers to which it is attached. A composite plate of the present invention enables the manufacture of gaskets that resist temperatures up to 550° C. under continuous service.

  • Patent number: 9059616
    Abstract: The invention discloses an insulation system for a stator bar in high voltage electric machines, comprising an anti-corona tape that is wound uniformly and continuously over the entire length of a bare bar. The anti-corona tape comprises a thin resistive sublayer engaged to a thick insulative sublayer. The insulative sublayer provides resistance against high voltage. The resistive sublayer protects the insulation against partial discharges. These partial discharges can occur in voids, such as delamination voids, transposition crossover gaps, strand corners, slot voids, overlap voids etc. The resistive sublayer also increases the thermal conductivity hence reduces the operating temperature. Such insulation using a single-tape approach can replace several layers used in prior-art, viz., an internal corona protection layer, an external corona protection layer, a stress-grading layer and mica layers. This single-tape approach also simplifies the process of manufacturing the stator bar and reduces its cost.

  • Patent number: 9011977
    Abstract: Microencapsulated chemical(s), as water-soluble solid particles, are embedded in at least one the paint layers on the surface of a magnesium article used in an automobile. If the protective paint film is scratched or otherwise mechanically disturbed to expose the surface of the magnesium article the capsules will be ruptured. This will expose the encapsulated chemical(s) to ambient water enabling them to dissolve and form an aqueous solution capable of reacting with the exposed magnesium to form a protective passivating layer on the exposed magnesium to resist corrosion. In a second embodiment the encapsulated chemicals include a deliquescing compound for extraction of moisture from the atmosphere sufficient to induce dissolution of the passivating layer-forming chemical(s) and trigger the formation of the passivating layer in the absence of ambient water.

  • Patent number: 8592522
    Abstract: The object of the present invention is to provide an oxygen-absorbing resin composition having a high oxygen absorbability and capable of absorbing oxygen for a long period of time. The present invention provides an oxygen-absorbing resin composition comprising polyolefin resin (A) obtained by polymerizing an olefin having 2 to 8 carbon atoms, resin (B) which is other than resin (A) and which acts as a trigger for the oxidation of resin (A), and transition metal catalyst (C), wherein resin (B) is dispersed in the matrix of resin (A) so that the oxidation reaction of matrix resin (A) is caused and thus oxygen is absorbed when the oxygen-absorbing resin composition is brought into contact with oxygen. This oxygen absorbing resin composition has a high oxygen absorbability and is advantageous in cost because oxygen is absorbed in resin (A).
