摘要:
The instant invention provides a method of forming a structure which includes at least two laminates each having a minor area of common overlap therebetween and a major area wherein said panels are not overlapped, which comprises the step of forming a primary, wet-to-wet resin bond between said minor areas of common overlap. The invention also contemplates at least one article of manufacture produced by the method.
摘要:
The invention concerns a patch or repair assembly for repairing vehicles, installations and parts. The assembly comprises at least one photocurable prepreg fabric, a UV transparent release film on top of the fabric and a UV blocking film over the release film. There is also disclosed a method of repairing using the assembly of the invention.
摘要:
A photocurable composition comprising the reaction products of hydroxy terminated liquid sulfide or polysulfide oligomers with photocurable ethylenically unsaturated compounds. The products provide improved sealants for air and marine vehicles.
摘要:
The present invention relates to a method for the volumetric decontamination of radioactive metals. The method includes the step of precipitating out radioactive gamma and beta emitting nucleotides and then recovering non-radioactive metal compounds.

摘要:
A fabric for chemical protective garments having at least two multilayered film laminates separated by a scrim forming a barrier chamber. The laminates are sandwiched between films of linear low density polyethylene and contain a different film from each other selected from ethyl vinyl alcohol, polyethylene terephthalate and polyamide. There is also the garment prepared with the fabric.
摘要:
A non-aqueous electrolyte for electric storage devices consisting of a nitrile solvent and a complex salt formed by the reaction of a tetraalkyl ammonium salt and hydrogen fluoride. The electrolyte may include a component which a cation of an imidazolium or quaternary tetraalkylammonium salt.
摘要:
There is provided concentrated aqueous solutions of highly pure lithium hydroxide essentially free of carbon dioxide, packaged in an inert atmosphere.
摘要:
There is provided a process for preparing tetraalkyl ammonium halide utilizing a catalytic amount of acetonitrile in a reaction under pressure and at an elevated temperature of an alkyl halide and a trialkyl halide and in which tetrafluoroborate can be subsequently prepared.
摘要:
A process for the preparation of anhydrous high purity phosphorus pentafluoride in high yield. The process uses an excess of hydrogen fluoride in a reaction with a phosphoric acid to form hexafluorophosphoric acid followed by reaction with a sulfur based acid reactant in a reaction medium containing an excess of hydrogen fluoride.
