Filed: 1952-10-13
Abstract: 4 - Halo - 21 - acyloxy - 17a  - hydroxypregnane - 3 : 11 : 20 - triones are prepared by halogenation of 21 - acyloxy - 17a  - hydroxypregnane-3 : 11 : 20-triones in tertiary butyl alcohol which may contain up to eighteen per cent of water by volume. Specified halogenating agents are chlorine, bromine, N-bromoacetamide, N - bromosuccinimide, N - chloro - succinimide, 3 - bromo - 5 : 5 - dimethyl hydantoin, 1 : 3-dibromo-5 : 5-dimethyl hydantoin, hypobromous acid and hypochlorous acid. The 21-acyloxy radicals preferably contain from one to eight carbon atoms inclusive and may carry halo, alkyl or alkoxy groups as non-reactive substituents. Traces of mineral acids expedite the reaction, which is preferably conducted below about 50 DEG  C. In examples (1) 21 - acetoxy - 17a - hydroxypregnane - 3 : 11 : 20-trione in tertiary butyl alcohol containing a trace of aqueous hydrogen bromide is treated with N-bromoacetamide to produce 4-bromo - 21 - acetoxy - 17a  - hydroxypregnane - 3 : 11 : 20-trione.  Other examples illustrate the halogenation of the 21-acetoxy-trione using each one of the agents specified above. Further examples relate to the formation of 4-bromo-21-propionoxy-, 4 - chloro - 21 - octanoyloxy - and 4 - chloro - 21 - butanoyloxy - 17a  - hydroxy - pregnane-3 : 11 : 20 - one, and many other 21 - acyloxy-4-halocompounds are listed.  The required intermediate 21-acetoxy-17a -hydroxypregnane-3 : 20-trione is prepared from 3 : 17a  - dihydroxypregnane - 11 : 20 - dione by bromination to yield the 21-bromo compound followed by treatment with potassium acetate in acetone, and finally oxidation with N-bromoacetamide in basic solution.

Abstract: 958,996. Air cushion vehicles. VICKERSARMSTRONGS Ltd. July 18, 1962 [July 18, 1961; Dec. 22, 1961], Nos. 26069/61 and 46080/61. Heading B7K. An air cushion vehicle has on its underside a skirt extending downwardly from the peripheral part of the vehicle body for encircling the air cushion, the skirt being of flexible material and at least part of the skirt being formed by discrete flexible members which depend from the underside of the vehicle body, adjacent flexible members of the skirt being substantially contiguous thereby to minimize escape of the air from the cushion. The vehicle may be of the plenum-chamber or peripheral fluid-curtain type, the flexible skirt being formed of a plurality of elements of the form shown in the base plan view of Fig. 1, though the end curtains only may be so constructed, the side skirts being flexible but continuous. The joints between contiguous elements may be covered by closing panels. As shown in Fig. 4, the individual elements 4 of the skirt are located outside the air curtain 8, though air curtains may be located one inside and another outside the skirt, or, as described in the first Provisional Specification, a pair of skirts may form a channel and nozzle for the air forming the curtain. The skirt elements may be hinged to the body and spring-loaded against outward movement caused by cushion pressure or they may be mounted on discrete inflatable supports, or they may be so constructed that cushion pressure tends to move them inwards. Other embodiments for use over water incorporate a planing surface which on contact with the water, causes its supporting skirt member to deflect rearwardly, rather than to dig in to the water or the skirt may comprise discrete elements each comprising verticallyspaced solid members secured to a flexible support which deflects when in contact with the water. In further embodiments the skirts may be hinged, or moved bodily, for and aft or sideways to provide a means of controlling pitching or rolling movements of the vehicle. The individual skirt members may be constructed from a solid flexible member of one hollow flexible member of one material, e.g. rubber sleeving another flexible member of steel or nylon. They may be of uniform or tapered section or they may be formed with a distinct change in section. The vehicle may be supported in part only by the air cushion and propulsion may be effected by either raising a part of the rear skirt or forming it with controllable apertures.
