IPC: C07J75/00
Filed: 1958-10-13
Abstract: The invention comprises (1) a process for preparing steroids having an aromatic ring A, a 1-methyl group and a 3-acyloxy group wherein a D 1,4-3,11-diketo-steroid is reacted with a carboxylic acid anhydride in the presence of a strong acid catalyst, either under mild conditions to yield a 1-methyl-3-acyloxy-D 1,3,5(10)-11-keto-steroid having a 9a -hydrogen atom or under forcing conditions to yield a 1-methyl-3,11-di-acyloxy-D 1,3,5(10),9(11) -steroid; (2) the new steroids of the formula <FORM:0934714/IV(a)/1> wherein R1 is a ketonic oxygen atom or a dihydroxy-acetone side chain or a mono- or di-ester thereof and R2 is a hydrogen atom or an acyl group, the 9-hydrogen atom having the a - or b -configuration but not the a -configuration when R1 is a dihydroxy-acetone side chain or a di-ester thereof; and (3) the new steroid 3,11,17a ,21-tetra-acetoxy-1-methyl-19-norpregna-1,3,5(10),9(11) -tetra-en-20-one.  The starting material in process (1) preferably has the formula <FORM:0934714/IV(a)/2> in which R1 is as defined above, keto groups in it being protected if necessary, and the process may then be combined with the further steps of hydrolysing the 3-acyloxy-9a -#H-11-ones to the 3-hydroxy compounds and with the further step of treating either of these with a strong acid or base to yield 3-hydroxy-9b -#H-11-ones or of reacting the 3-acyloxy-9a -#H-11-ones with a carboxylic acid anhydride in the presence of a strong acid catalyst under forcing conditions to yield 3,11-diacyloxy-D 9(11)-steroids which may then be hydrolysed to yield the 3-hydroxy-9b -#H-11-ones.  It is stated that although the 9b -epimer is the predominant product of these processes, some of the 9a -epimer is usually also formed.  Mild conditions are defined as low concentrations of catalyst and/or short reaction times and/or low reaction temperatures, but it is stated that whatever conditions are employed, a mixture of products is frequently obtained, these being separated by chromatography.  Keto groups may be protected by semicarbazone formation or formation of bis-methylenedioxy derivatives. Unprotected keto groups are enolacylated in the process involving acid anhydrides and free hydroxy groups are generally acylated. Hydrolysis of 3-acyloxy compounds may simultaneously involve hydrolysis of 17- and 21-acyloxy groups.  Hydroxy groups may subsequently be reacylated.  Acid anhydrides referred to are those of acetic, propionic and butyric acids, and strong acids mentioned are sulphuric, perchloric and toluene-p-sulphonic.  Detailed examples are given.  The Provisional Specification describes steroids of the formula <FORM:0934714/IV(a)/3> where R is hydrogen or an acyl group; R1 is hydrogen or an alkyl group; R2 is hydrogen, a hydroxy or acyloxy group, a ketonic oxygen atom, an acetyl group, a hydroxy or acyloxy-acetyl group, a dihydroxy-acetone chain or a mono- or di-ester thereof; R3 is hydrogen or a hydroxy or alkyl group and R4 is hydrogen or an alkyl group or a fluorine atom, the 9-hydrogen atom having the a - or b -configuration.

Patent GB-962245-A (GB)
Title: Mobile dispensing freezer
IPC: A23G9/22
Filed: 1961-09-14
Abstract: 962,245. Refrigeration. SWEDEN FREEZER MANUFACTURING CO. Sept. 14, 1961 [Sept. 19, 1960], No. 32954/61. Heading F4H. A dispensing freezer 5, e.g. in a motor vehicle, has a rotary dasher 11 which is driven from the output shaft 44 of a power source, e.g. I.C. engine 35, through a normally disengaged clutch 42 which automatically engages at a given output shaft speed. In the arrangement shown, the engine 35 is normally idling at low speed under control of governor 38, but energization of solenoid 26 actuates throttle arm 36 to step up the engine speed to a higher level. Before the speed reaches this level, the centrifugal clutch engages and drives both the dasher shaft 49 and shaft 50 of refrigerator compressor 6 through the reduction belt and pulley connections shown. In the refrigerating system for the freezer, the compressor output passes via condenser 7, liquid receiver 8 and expansion valve 29 to evaporator jacket 15 and return pipe 16. When the temperature in jacket 15 rises above a predetermined level, thermostat 30 closes switch 27 to energize both the solenoid 26 and solenoids 23, 24 which open normally closed valves 21, 22 in the refrigeration circuit. Solenoid 26 is energized also by closure of switch 28 when the gate 32 in dispensing head 13 is opened; this ensures that the dasher operates when dispensing of the frozen mix required. If, at this time, valves 21, 22 are closed, the resulting low pressure on the suction side of compressor 6 causes a valve 20 to open automatically and allow refrigerant to be fed back through by-pass pipe 19 from the condenser 7. In a modification, the engine 35 is normally switched-off and solenoid 26 actuates starting mechanism. In an alternative arrangement (Fig. 3, not shown), including a secondary refrigeration load e.g. a cold storage container, the compressor 6 and dasher 11 are driven through separate speed-responsive clutches, the second clutch enabling the engine to be started free of load. At the lower engine speed, the compressor is driven at sufficient speed to satisfy the requirements of the secondary load, while at the higher speed both the compressor and the dasher are driven as in the arrangement shown. Specification 779,446 is referred to.

Title: Improvements in voice-operated switching arrangements for transmission systems
IPC: H04B1/46
Filed: 1958-10-16
Abstract: 892,636. Two-way transmission. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 16, 1958 [Oct. 19, 1957], No. 33053/58. Class 40 (4). In an arrangement connecting a two-wire circuit a to a four-wire circuit E, R, suppression means are controlled jointly by a circuit B responsive to incoming signals over the circuit R and a circuit A connected in the twowire line a and arranged to provide an output only if the signals passing therethrough have originated from the two-wire line, the arrangement comprising a network having two terminals, the relative phases of signals thereon being different according to the direction of the signal, the terminals being connected to a phase comparator which gives the desired output. As shown, the suppression means comprises relay contacts I 1  controlled by opposing coils c and d energized by A and B respectively. The relay may have an additional winding (not shown) connected to contacts I 2  arranged to have current flowing in such a direction as to tend to maintain the relay in whichever position it happens to be. The details B, Fig. 3, (not shown), comprises a conventional amplifier followed by a push-pull detector and limiter. This detector cannot be affected by speech from a due to the presence of the intervening one-way amplifier G. The device A, Fig. 4, comprises two transformers whose primary windings A 1 , A 2  are connected respectively to the handset side a and the contacts I 1  of Fig. 1. The secondaries are interconnected by a resistance network from which two tappings leading to the grids of V 5 , V 6  are taken, the connections being such that for signals on A 1 , A 2  the signals or the tappings are in anti-phase or in phase respectively. The respective signals are amplified by valves V 5 , V 7  and V 6 , V 8  and fed to a phase comparator comprising diodes D 4 , D 5  and a lowpass filter C 11 , C 12 , R 27  arranged to give a positive output in the case of in-phase signals due to an input over A 2  from the receive side, and a negative output in the case of out-ofphase signals due to an input over A 1  from the two-wire side. In the first instance the positive output is suppressed due to the back-biasing of diode D 6  which receives a positive threshold bias from source U 4 . In the second instance, if the negative output is sufficient to overcome the threshold bias it passes to the output terminal though subjected to a maximum numerical value by a limiting diode D 7 . The fourwire circuits E and R may be connected to a radio transmitter and receiver respectively.
