Title: Improvements in or relating to 19-halo-10-a-androstane compounds
IPC: C07J1/00
Filed: 1963-10-28
Abstract: The invention comprises steroids of the formulae <FORM:1055245/C2/1> wherein R1 is hydrogen or the acyl radical of a hydrocarbon carboxylic acid of less than 12 carbon atoms which may be substituted; R2 is hydrogen, or alkyl, alkenyl or alkynyl of at most 8 carbon atoms; Z is hydrogen, methyl, chlorine or fluorine; X is chlorine or fluorine; and Y is a double bond or a saturated linkage between C-1 and C-2.  They are prepared from the 17-acetate of 19-hydroxy-10a -testosterone, either by reaction with an a -fluorinated amine to give the acetate of 19-fluoro-D 4-10a -androsten-17b -ol-3-one, or by reaction with tosyl chloride to give the 19-tosylate and reaction of this with an alkali metal halide to give the acetate of 19-fluoro- or 19-chloro-D 4-10a -androsten-17b -ol-3-one, which on saponification give the corresponding 17-ols. The D 4-3-ketones, on reaction with ethyleneglycol give D 5-3-ketals, these on oxidation give the corresponding 17-ones, these with an alkyl Grignard reagent or an alkali metal alkynyl compound give the 17a -alkyl or -alkynyl-17b -ols, and these are converted to the D 4-3-ones by acid hydrolysis, or to 5a ,6a -oxido compounds by reaction with an organic per-acid.  The oxido compounds are reacted with methyl Grignard reagents and the products treated with a mineral acid and then with thionyl chloride in pyridine to give 19-halo-6b -methyl-D 4-10a -androsten-17b -ol-3-ones which are converted to the 6a  isomers by alkali metal hydroxide treatment.  With hydrogen chloride, or hydrogen fluoride followed by acid treatment, the 5a ,6a -oxido compounds give 19-halo-6a -chloro and fluoro - D 4 - 10a  - androsten - 17b  - ol - 3 - ones. Conversion of the D 4-3-ones to D 3,5-3-enol ethers and reaction of these with N-chloroamides or -imides or perchloryl fluoride in dimethylformamide gives the 6b -chloro or fluoro-19 - halo - D 4 - 10a  - androsten - 17b  - ol - 3 - ones. 17a -alkenyl compounds are prepared by reduction of 17a -alkynyl compounds.  D 4,6-compounds are prepared by reaction of the D 3,5-3-enol ethers with approximately 1 mole of 2,3-dichloro - 5,6 - dicyano - 1,4 - benzoquinone in the presence of an acid catalyst. Prolonged refluxing of the D 4-3-ones with this quinone gives the corresponding D 1,4-3-ones, while under similar conditions the D 4,6-3-ones are converted to D 1,4,6-3-ones.  17-Esters are prepared by conventional acylation procedures.  Examples are given.  19 - Hydroxy - 10a  - testosterone 17 - acetate is prepared by heating the 17-ol with trityl chloride in pyridine and reacting the product with acetic anhydride.  The 19-halo-10a -androstane compounds of the invention, which are stated to have anabolic-androgenic properties and anti - estrogenic activity, to lower the blood, liver and adrenal cholesterol levels, and to be useful in the control of fertility and psychotic conditions and as appetite stimulants, may be made up into pharmaceutical compositions with suitable carriers.

Abstract: 973,806. Lubricating systems. TECALEMIT Ltd. Dec. 4, 1961 [Dec. 22, 1960], No. 44052/60. Heading F2A. [Also in Divisions F1 and H2] A lubricating system wherein lubricant is delivered to different points in a motor vehicle comprises a solenoid-operated pump 3 which receives lubricant via a supply pipe 5 from a reservoir 4, and a control switch 1 of the rotary cam type which is driven from a rotating port of the vehicle e.g. the gear-box and which effects energization of the solenoid to actuate the pump. Located coaxially in the body 8 of the pump are primary and secondary windings of the solenoid, connected in series, and a reciprocating armature 10 having a spring-loaded rod 12, located coaxially therein, the lower end of which contacts a piston formed by a rod 26 which in turn is biased by a spring 27 so that piston and armature remain in axial contact. The stem portion 9 of the body 8 houses a cylinder 18 within which the piston 26 is slidably located and which carries a spring- loaded ball type check valve 23 which closes the axial bore in the cylinder 18. Lubricant is supplied to the cylinder from the reservoir 4 via port 20 and is discharged through ports 21 via the check valve 23 by the reciprocating action of the piston when the solenoid is energized. The lubricant discharge ports 21 communicate with an annular chamber 22 between disc-shaped plates 29, 30. The lower plate 30 houses a number of lubricant connectors 32 and pipes 33, connecting the pump to the various points in the system. The upper plate 29 is provided with an aperture 34 to receive an air vent line. The operation of the rotary switch 1 energizes the primary winding of the solenoid which draws the armature 10 and rod 12 upwards. At the upper limit of its travel the rod 12 opens the shorting switch 15 to permit energization of the secondary winding to reduce the current flow. The rotary switch 1 subsequently breaks the circuit and the piston and armature are forced downwards by the spring 16 to discharge lubricant through the ports 21 and pipes 33 to the points in the system.

Abstract: 1362836 Radio signalling MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 29 Sept 1971 [2 Oct 1970] 45417/71 Heading H4L In a system for receiving signals from mobile radio stations, such as motor vehicles, a number of fixed receiving stations are provided which are distributed at known positions within the service area, and which are divided into groups each associated with a respective relay station. Each receiving station has an individual transmission line to its relay station, and each relay station has an individual transmission line to a central station. The lines from each relay station to the associated receiving stations are successively scanned, and the output from each relay station is processed in the central station. As described, a message from a motor vehicle comprises an identification number and such information as whether or not it has a passenger. A feature is, that the message may be sent at a repetition frequency which is proportional to the speed of the vehicle (Fig. 1, not shown). At a relay station the lines from its receiving stations are successively scanned by a circuit 11, Fig. 4, controlled from the central station by a synchronizing signal and by clock pulses which correspond in number to the greatest number of receiving stations coupled to a relay station, and which have a period at least equal to the time required for a mobile station signal to be received at the central station. The transmission lines from the relay stations are connected at the central station to the inputs of respective demodulators 21 to 24, Fig. 5, which provide outputs to a central processing section 15. This reads out and stores the information from the mobile station signals and operates peripheral circuitry, which may comprise printing means, so that, for example, it it known which receiving station is in contact with which mobile station at a particulr time. The processing section 15 also sends out, on a line "e", the synchronizing and scanning control signals to the relay stations.
