Title: Process for the manufacture of water-soluble derivatives of cyclopentano-perhydro-phenanthrenes
IPC: C07J75/00
Filed: 1936-04-18
Abstract: Water soluble sulphonic acid derivatives of compounds of the cyclopentanoperhydrophenanthrene series are prepared by the careful sulphonation of compounds of the above series which contain a keto group in either ring A or B of the ring system.  In addition to the keto group, the starting materials may also contain further substituents such as hydroxy and alkoxy groups. Carbonyl groups and carboxyl groups may also be present in the two other nuclei of the ring system or in the side chain.  The preferred method of sulphonation is by the action of concentrated sulphuric acid in the presence of acetic anhydride at low temperature.  Specified starting materials include cholestenone, progesterone, androstendione, 7-oxocholestene, cholestanone and coprostanone.  The sulphonic acids obtained according to the present invention may be transformed into neutrally reacting salts, and also into the corresponding esters and acid amides.  In examples: (1) a solution of cholestenone in acetic anhydride is treated with a mixture of concentrated sulphuric acid and acetic anhydride at 0 DEG  C.  The sulphonic acid separates and is washed with glacial acetic acid.  It is soluble in water as also are its alkali salts in dilute solution, but which form gels in concentrated solution.  The alkaline earth and heavy metal salts are difficultly soluble in water, but readily soluble in benzene + alcohol, or chloroform.  The bismuth salt forms a clear solution in soya oil.  In a similar manner 7 - oxocholestene sulphonic acid may be obtained; (2) an acetic anhydride solution of androstendione is treated at 0 DEG  C. with a mixture of concentrated sulphuric acid and acetic anhydride.  The sulphonic acid which separates is very hygroscopic and is dried over soda lime.  In a similar manner progesterone also yields a sulphonic acid; (3) a paste of cholestanone and acetic anhydride is added to a mixture of concentrated sulphuric acid and acetic anhydride and the mixture stood on ice for 12 hours.  The sulphonic acid separates and is recrystallized from acetic acid.  Coprostanone when sulphonated as in example (3) gives a sulphonic acid which is readily soluble in all organic solvents.

Abstract: 966,679. Measuring electrically. BORGWARNER CORPORATION. March 27, 1961, No. 11184/61. Drawings to Specification. Heading G1N. A force measuring transducer includes a plurality of pairs of coaxial stretched strings, each pair being at an angle to each other pair, a force responsive element joining the two strings of each pair, means for vibrating the strings at their natural frequencies, and means for indicating the difference in frequency between the two strings of each pair to determine the magnitude and direction of the force acting on the element. An arrangement similar to that described in Specification 880, 361 is used for each axis of a triaxial accelerometer, a single force responsive element being common to all the pairs of wires and being supported solely by the wires in the present case. The outputs from the three mutually perpendicular axes are derived independently. It is stated that the device may be mounted on a stable platform in a missile, the platform being fixed relative to the absolute vertical to avoid gravitational errors. A biaxial accelerometer is also referred to. The two strings of each pair may have different natural frequencies of vibration, e.g. they may have different lengths, densities, cross-sectional areas or moduli of elasticity. The strings of each pair may also vibrate in different planes to each other to minimise mechanical coupling. Strings having ribbonlike or polygonal cross-sectional are also envisaged, and may be of non-metallic material with a conductive coating.
