Abstract: 991,355. Nose cones for projectiles. STUDEBAKER CORPORATION. Aug. 29, 1963, No. 34192/63. Heading F3A. [Also in Division B5] A nose cone 12 for a projectile is formed on a mandrel 18 of frusto-conical shape, the surface having a stepped profile. Around the lowermost step 19 is a ring 21, with a frusto-conical surface 23, bolted to a plate 24, which can be attached to a flange 28 of a rotatable shaft 29. On rotating the shaft, resin-impregnated circumferential rovings 31, of glass fibre or like filamentary material, are wound on the mandrel until an unbroken surface is obtained. Resinimpregnated fabric laminations 33 are then placed lengthwise over the windings. These laminations may be glass fibre cloth sheets, and are covered by a further layer of circumferential rovings. Further layers of lengthwise laminations 36 and windings 37 are built up and the outermost surface covered with lapped circumferential windings 38 of a tape or strip 39 made of resin-impregnated glass fibre cloth. The tape has slits 41 to permit even winding. When the winding is complete, the laminations are heated and moulded, in equipment not shown to cure the resin, which may be a phenolformaldehyde resin. The nose cone is then removed from the mandrel and finished by machining. The steps 44 on the inner surface of the cone may be used to secure internal structures in position and a nose cap 13 is attached.

Filed: 1962-09-13
Abstract: The invention comprises steroids of the general formula <FORM:1023782/C2/1> wherein R represents hydrogen or an alkyl radical and X represents a 2,2,2-trifluoroacetyl radical, or R represents an alkanoyl or alkyl radical and X represents a 2,2,2-trifluoro-1-alkanoyloxyethylidene radical, and of the general formula <FORM:1023782/C2/2> wherein R represents hydrogen or an alkyl radical and X represents a 2,2,2-trifluoroacetyl, 2,2,2-trifluoro - 1 - hydroxy - ethyl or 2,2,2-trifluoro - 1 - alkoxy - ethyl radical, or R represents an alkanoyl or alkyl radical and X represents a 2,2,2-trifluoro-1-alkanoyl-oxyethylidene, 2,2,2-trifluoroethyl or 2,2,2-trifluoro-1-alkoxyethyl radical (in the above formulae the alkanoyl, alkoxy and alkyl groups have from 1 to 4 carbon atoms). The above compounds may be prepared by condensing androstenolone or androstanolone or the corresponding 3-alkoxy compound in either case with an alkyl ester of trifluoroacetic acid in the presence of an alkaline condensing agent to introduce a trifluoroacetyl radical at the 16-position, reacting this product with formic acid or an alkanoic acid anhydride to form the corresponding enol alkanoate derived from the keto group contained in the 16-substituent and hydrogenating the enol alkanoate to form a 16-trifluoroethyl substituent at the 16-position.  The previously prepared 16-trifluoroacetyl compound may then be hydrogenated to form a trifluorohydroxyethyl group at the 16-position with simultaneous hydrogenation of a double bond at the 5-position, the saturated product may then be acylated both at the 3-position and in the 16-side chain by treatment with an alkanoic acid anhydride and the resulting 2,2,2-trifluoro-1-alkanoyloxy substituent at the 16-position may be converted to a 2,2,2-trifluoro-1-alkoxyethyl substituent by the action of alkali-strong alkali also hydrolyses a 3-alkanoyloxy group if present whereas with weak alkali the 3-alkanoyloxy group survives (the latter type of compound may also be obtained by reacylation of the 3-hydroxy compound obtained by the action of strong alkali).  Pharmaceutical compositions having an anti-inflammatory action contain as the active ingredient a steroid of one of the general formulae above.  The compositions may be applied parenterally or topically in aqueous suspensions or in innocuous organic solvents.
