Title: Improvements in or relating to steroids and the manufacture thereof
IPC: C07J5/00
Filed: 1958-11-25
Abstract: The invention comprises compounds having the formulae <FORM:0874374/IV (b)/1> <FORM:0874374/IV (b)/2> <FORM:0874374/IV (b)/3> wherein the 1,2-carbon atom linkage is a single or a double bond linkage, Z is a halogen, and X is the carbonyl radical or the hydroxymethylene radical a process which comprises treating 6-fluoro-11-hydroxy-4-pregnene-3,20-dione with a dehydration agent to obtain 6-fluoro-4,9(11)-pregnadiene-3,20-dione, which on treatment with hypohalous acid in which the halogen is bromine chlorine or iodine gives 6-fluoro-9a -halo-11b -hydroxy-4-pregnene-3,20-dione; said 9a -halo compound is treated with a mild base to give 6-fluoro-9,11b -oxido-4-pregnene-3,20-dione which on treatment with hydrogen halide, e.g. HF, HCl, HBr gives the corresponding 6-fluoro-9a -halo-11b -hydroxy-4-pregnene-3,20-dione which can be oxidised to produce 6-fluoro-9a -halo-4-pregnene-3,11,20-trione. The 6-fluoro-9a -halo-11-oxygenated-4-pregnene-3,20-dione may then be dehydrogenated using microorganisms, e.g. Septomyxa, Corynebacterium, Didymella, Calonectria, Alternaria, etc. to obtain 6-fluoro-11b -hydroxy-1,4-pregnadiene-3,20-dione and 6-fluoro-1,4-pregnadiene-3,11,20-trione.  The dehydrogenation may also be effected chemically by means of selenium dioxide. Alternatively the D 1,4-pregnadienes are obtained by a similar series of reactions starting with 6-fluoro-11b -hydroxy-1,4-pregnadiene-3,20-dione which is obtained by dehydrogenating 6-fluoro-11b -hydroxy-4-pregnene-3,20-dione. The process of the invention is applicable to both 6a  and 6b -fluoro compounds.  The 6b  compounds are converted into 6a  compounds by treatment with hydrogen halide, e.g. gaseous HCl. Alternatively epimerisation of the 6b ,9a -di-fluoro compounds may be effected with alkali.  Specific compounds claimed are 6,9a -difluoro-11b -hydroxy-4-pregnene-3,20-dione, 6,9a  - di-fluoro-4-pregnene-3,11,20-trione, 6,9a -difluoro-11b -hydroxy-1,4-pregnadiene-3,20-dione, 6,9a -difluoro - 1,4 - pregnadiene - 3,11,20-trione, 6-fluoro-9a -bromo - 11b  - hydroxy - 4 - pregnene-3,20-dione, 6-fluoro-9a -bromo-11b -hydroxy-1,4-pregnadiene-3,20-dione, 6-fluoro-9,11b oxido-4-pregnene-3,20-dione, 6-fluoro-9,11b -oxido-1,4-pregnadiene-3,20-dione, 6-fluoro-4,9(11)-pregnadiene-3,20-dione and 6-fluoro-1,4,9(11)-pregnatriene-3,20-dione.

Title: Improvements in or relating to electric motor control systems
IPC: H02P1/20
Filed: 1930-12-16
Abstract: 365,741. Master control of motors. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and CROFT, E. H., of General Electric Co., Witton, Birmingham. Dec. 16, 1930, No. 37912. Drawings to Specification. [Class 38 (iii).] A master control system for trolley buses &c. comprises means for effecting automatic acceleration of the motors and means operable by the driver to vary the rate of acceleration. The system is described with reference to a vehicle having two series motors, the master controller having the following positions, off, first series with all armature resistance in circuit, several series positions in which acceleration proceeds automatically to the full series connection but at varying rates. and several parallel positions in which acceleration proceeds automatically to the full parallel connection with weakened field but at varying rates. In one system acceleration is controlled by a pair of relays opened alternately and closed with a delay imposed by a dashpot, the extent of opening being limited by a cam associated with the master controller in such a manner that the further the master controller is moved from its " off " position the less is the movement of the relay and hence the less is its delay in closing and thus the greater is the rate of acceleration of the motors. In this system the relays control the sequential operation of contactors. In an alternative system the sequential operation is controlled by a drum controller driven by a pilot motor, the speed of which, and hence the rate of acceleration of the main motors, is increased as the master controller is moved from its " off " position.

Abstract: 1439167 Selective signalling MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 13 Aug 1973 [12 Aug 1972 (2)] 38220/73 Heading G4H [Also in Division H3] A remote control system, more particularly for a television receiver, uses a light control signal which is modulated by a high-frequency signal itself modulated with a low-frequency signal: in the transmitter two transistors are cross-coupled to form a multivibrator which "chops" the high frequency signal generated by one of the transistors, which is back-coupled to form a high-frequency oscillator. Remote control transmitter.-Transistors 1, 2, Fig. 3a are arranged to produce high-frequency oscillations chopped at a low frequency, Fig. 2c (see Divisions H3-H5). A coupling winding 22 drives transistor 24 whose emitter circuit includes the light-emitting diode 25. The arrangement is energized by closing switch 18A; if switch 18B is closed instead, switch 21 closes with it and introduces capacitors 20A, 20B and so changes the transmitted high frequency to provide a different control function. Remote control receiver.-The modulated light signals are picked up by a photo-transistor 26, Fig. 4a, the output of which is amplified by amplifier 28 and following transistor 29. The two transmitting high frequencies are separated by tuned circuits 30, 31 each of which is followed by a detector circuit 32, 33 respectively.

Abstract: 1,188,115. Telegraphy. MARCONI CO. Ltd. 31 May, 1967 [1 Sept., 1966], No. 38987/66. Heading H4P. [Also in Division G4] In a teleprinter receiver in which the received signals are stored on bi-stable units which control respective mechanical recording members, e.g. in a printer or punch, means are provided for checking that the settings of the bi-stables and of the members correspond. In one embodiment each bi-stable has two output leads which have opposite polarities, the polarities being reversed when the bi-stable changes its setting. A switch passes one or other output to a gate common to all the switches. The switches are mechanically coupled to the respective recording members so that when a member is operated the associated switch reverses. The gate passes any, say, positive voltage. Thus if a bi-stable in the rest position gives a negative potential on the lead connected to the switch, when the bistable is set the switch reverses and so still applies a negative potential to the gate. If the recording member does not operate, however, the switch does not reverse and so a positive potential passes through the gate. The gate output feeds a second gate enabled by pulses at character rate. The output of the second gate inhibits further operation of the punch and operates an alarm. The character rate pulses are delayed somewhat with respect to the operation of the recording members to allow the members to come to rest so avoiding incorrect indication of a fault due to contact bounce. In an alternative embodiment each bi-stable has only one output lead, which is connected to the switch both direct and via an inverter.

Abstract: 1,172,009. Separating aliphatic hydrocarbon chlorination products. FARBWERKE HOECHST A.G. 30 Aug., 1967 [30 Aug., 1966], No. 39702/67. Heading B1L. [Also in Division C2] The reaction mixture from the chlorination of an aliphatic hydrocarbon having a boiling point below that of hydrogen chloride, e.g. methane, and which comprises unreacted hydrocarbon, hydrogen chloride and chlorinated hydrocarbons, e.g. methyl and methylene chlorides, chloroform and carbon tetrachloride, is separated by washing the reaction mixture in the gas phase with the liquid monochlorinated product of the hydrocarbon. As shown, reaction mixture from reactor A passes by line 1 to column C where it ascends in counterflow to mono-chlorinated hydrocarbon wash fluid entering by line 8. Generally, column C is maintained at 1-35 atmos. gauge and -50 to 20‹C. The bottom product of chlorinated hydrocarbons passes by line 3 to distillation column F where it is fractionated. Overhead gas from column C passes by line 2 to column D where it ascends in counterflow to HCl-free chlorinated hydrocarbon fed by line 7. If desired, HCl may be added to line 7 to control the HCl level of the cycle. The overhead of unreacted hydrocarbon is recycled to reactor A by line 4. Bottom product of HCl-containing monochlorinated hydrocarbon from column D is partly returned by line 8 to column C, but most passes by line 9, together with the overhead from column F in line 6, to column E. It is there separated into an overhead of pure HCl gas, and a bottom product of pure monochlorinated hydrocarbon which are recycled by line 7 to column D; part may be fed by line 10 into line 3.
