Abstract: A universal tip for an electrofusion tool including a main body configured to be electrically connected to an electrical lead of the electrofusion tool, and a contact supported by the main body being capable of transferring a voltage from the electrofusion tool to a pipe fitting. The contact is adjustable between a first configuration, in which the contact is configured to engage a first terminal having a first size, and a second configuration, in which the contact is configured to engage a second terminal having a second size that is different than the first size.

Abstract: A method of growing a FE material thin film using physical vapor deposition by pulsed laser deposition or RF sputtering is disclosed. The method involves creating a target to be used for the pulsed laser deposition in order to create a KBNNO thin film. The resultant KBNNO thin film is able to be used in photovoltaic cells.

Abstract: A ferroelectric perovskite composition, comprising a perovskite oxide ABO3, and a doping agent selected from perovskites of Ba(Ni,Nb)O3 and Ba(Ni,Nb)O3-?.

Abstract: Single-component bodies useful in fuel cells and other electrochemical devices are provided. In preferred embodiments, the single-component bodies comprise an anodic region at a first side, a cathodic region at a second, non-adjacent side, and an oxygen ion-conducting region substantially free from anodic or cathodic character disposed between said anodic and cathodic regions. The single-component bodies comprise either transition metal perovskites or oxide electrolytes such as yttria-stabilized zirconia doped with multivalent cations.

Abstract: A dispersion of finely divided particles of a magnetic material in an organic liquid containing a dispersant comprising an amine carrying a poly(carbonylalkyleneoxy) chain (PCAO chain) in which the alkylene groups contain up to 8 carbon atoms, or an acid-salt thereof. The dispersion is useful for the preparation of magnetic recording media such as video, audio and computer recording tapes and discs. Certain of the dispersants are novel, especially a polyethyleneimine carrying at least two PCAO chains.

Abstract: The present invention relates to a fluidizing agent which is a substituted ammonium salt of an N,N'-disubstituted diaminostilbene sulphonic acid wherein there is at least one organic radical containing at least 2 carbon atoms attached to the nitrogen atom of the substituted ammonium ion. The agent is useful for improving the fluidity of a dispersion of a polycyclic vat dye pigment in an organic liquid.
