The palladium complex disclosed herein is bis[tri(orthotolyl)phosphine] palladium which is produced by reacting a palladium salt with tri(ortho-tolyl)phosphine and reducing the resultant bis[tri(ortho-tolyl)phosphine] palladium salt with an alcoholic alkali. This complex is useful as a catalyst for the production of 1,3-diene oligomers.

A substantially phase insensitive complex envelope detector for continuously detecting on an analog basis the amplitude R(t) of a time varying complex vector whose base-band voltage quadrature signals x(t), y(t) are of the form R(t)=x(t)+jy(t). An approximation technique utilizes circuits which project the x(t), y(t) components parallel to vectors at angles .theta..sub.1 through .theta..sub.n, and summing circuits which combine these projections to give the approximate complex vector R(t). For a...

Novel heterogeneous, nickel-containing catalysts comprising A. a nickel carbonyl complex, and B. an acidic, solid, silica-based material are active in numerous reactive environments such as oligomerization, including homo- and co-dimerization, and polymerization of various olefins. In specific aspects, bis (triphenylphosphine) nickel dicarbonyl supported on an acidic, calcined, silica-alumina support containing a separate alumina phase, is active in, for instance, the oligomerization, particular...

In a complex sound wave wherein the information bearing group of resonances vary within different frequency regions in the sound spectrum, the detected signals derived from said group of resonances are regrouped in prearranged numerical combinations sequentially until a reference regrouping is established for neutralizing said variations.
