    • This invention is concerned with polymorphic forms of the compound N-�1(R)-�(1,2-dihydro-1-methanesulfonylspiro�3H-indole-3,4'-piperdin!-1'-yl)carbonyl!-2-(phenylmethyloxy)ethyl!-2-amino-2-methylpropanamide methanesulfonate which is a growth hormone secretagogue that is useful in food animals to promote their growth thereby rendering the production of edible meat products more efficient, and in humans, to treat physiological or medical conditions characterized by a deficiency in growth hormone secretion, and to treat medical conditions which are improved by the anabolic effects of growth hormone. The instant polymorphic forms have advantages over the other known forms of N-�1(R)-�(1,2-dihydro-1-methanesulfonylspiro�3H-indole-3,4'-piperdin!-1'-yl)carbonyl!-2-(phenylmethyloxy)-ethyl!-2-amino-2-methylpropanamide methanesulfonate in terms of thermodynamic stability and suitability for inclusion in pharmaceutical formulations. The present invention is also concerned with processes for preparing these polymorphic forms, pharmaceutical formulations comprising these polymorphic forms as active ingredients and the use of the polymorphic form of the compound and their formulations in the treatment of certain disorders.

    • A method of producing a composite powder by providing particles of (I) tungsten, niobium, zirconium, titanium or mixtures thereof, (II) silicon and (III) carbon in a proportion relative to each other so as to possess an overall chemical composition in that segment of the ternary diagram of FIGS. 2(a), 2(b), 2(c) and 2(d) designated A, and subjecting the particles to a mechanical alloying process under conditions and for a time sufficient to produce the composite powder. Also disclosed is a method of forming a substantially oxygen-free composition of matter comprising a matrix substance of WSi.sub.2, NbSi.sub.2, ZrSi.sub.2, TiSi.sub.2 or alloys thereof having SiC dispersed therein, the method comprising consolidating the above-described composite powder. Also disclosed is a method of forming oxidation- and wear-resistant coatings by subjecting the composite powder whose composition lies in segment A to a metallurgical process such as plasma spraying. A method of forming a composite material of uniformly dispersed particles of silicon carbide in a silicide or an alloy silicide matrix is also disclosed. The matrix contains alloy silicides such as (Mo,W)Si.sub.2. The volume fraction of the silicon carbide may be varied from 10-90%. A method is also disclosed for producing hybrid composites consisting of a third phase of fibers or whiskers dispersed among a silicide/silicon carbide two-phase microstructure derived from the composite powder.
