The compounds are prepared by reacting a compound of formula in which either V 1 <SP>1</SP> is H, NH 2 , -NHalkyl or OH and V 2 <SP>1</SP> is a halogeno acyl group or V 1 <SP>1</SP> is a halogen atom and V 2 <SP>1</SP> is hydrogen, halogen, alkyl, alkoxy, CN, or SO 3 H with the required aminophenolsulphonic acidamide to produce a compound of Formula I where R is hydrogen and subsequently reacting this compound with an etherifying agent. Suitable etherifying agents are benzene sulphonic acid esters of formula where X is alkyl, alkoxyalkyl or cyclohexyl. Alternatively the etherifying agent may comprise a mixture of an arylsulphonic acid halide and an alcohol. In one embodiment of the process, a compound of Formula I where V 2  is SO 3 H may be reduced to split off the SO 3 H group either before or after etherification.

Title: Improvements in the control of electron discharge tubes
IPC: G05B11/01
Filed: 1951-06-19
Abstract: 695,162. Converting. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. June 19, 1951 [June 19, 1950], No. 14571/51. Class 38 (ii). [Also in Group XXXVII] Conduction of an A.C.-fed discharge tube, through which a D.C. load is supplied, is initiated by a firing signal which increases the amplitude of a high frequency carrier voltage superposed on a low frequency grid bias voltage which is in phase quadrature with the anodecathode circuit voltage. The grid circuit also includes a source of negative bias voltage which prevents conduction until the amplitude of the high-frequency voltage, which may be of, say, 1000 cycles per second, exceeds a predetermined value, after which the tube conducts progressively earlier in the anode voltage cycle with increasing amplitude of the high-frequency voltage. In the motor control system shown, the motor 1, 29, 30 is supplied over transformer winding 25 and discharge tubes 21, 22 for one direction of rotation and over winding 26 and tubes 23, 24 for the reverse direction. The quadrature voltages for the grids of the tubes are obtained from a phase-shift circuit 6 energized by a further winding 5 of the transformer. High-frequency grid-control potentials are injected in series with the quadrature voltages by windings 35, 36 of a transformer 10 and winding 59 of a transformer 55, transformer 10 being energized by a frequency converter 9 fed from a winding 8 of the main transformer and transformer 55 being excited by an amplifier 54 fed with an input signal comprising an adjustable high-frequency voltage obtained from a potentiometer 41 fed by a winding 39 of transformer 10 and a " modulated " high-frequency signal provided by a further winding 42 of the same transformer, a ring modulator 48-51 and a tachometer generator 12 driven by the motor. Negative grid bias is applied between earth and the centre tapping of winding 59 of transformer 55. Potentiometer 41 determines the speed and direction of rotation of the motor. Simultaneous energization of both pairs of tubes 21, 22 and 23, 24 is prevented by the transformer windings 35, 36, which are so connected to the transformer winding 59 that when winding 59 assists winding 35, it opposes winding 36 and vice versa. The system may be modified for operation from a polyphase supply.

Title: Improvements in or relating to the production of bis(hydroxyphenyl) compounds
IPC: G05B11/01
Filed: 1952-09-19
Abstract: Bis (hydroxyphenyl) compounds are prepared by reacting phenolic compounds with carbonyl compounds in an aqueous acidic medium containing at least twice as much water by weight as phenolic compound.  The products may be represented by the formula <FORM:0711122/IV (b)/1> where each R, which may be the same or different, is hydrogen or an alkyl, cycloalkyl, aryl, alkaryl or aralkyl radical.  The phenolic radicals may be further substituted by similar radicals. Examples of carbonyl compounds are formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, isobutyraldehyde, n-valeraldehyde, trimethylacetaldehyde and benzaldehyde.  In addition to phenol and alkyl substituted phenols, such compounds as o- and p - phenyl phenols, naphthols, phenanthrol, cresylic acid and compounds having more than one hydroxy group in the nucleus are mentioned. Examples of acidic catalysts are sulphuric, hydrochloric, acetic, p-toluene sulphonic, alkane sulphonic, phosphoric, sulphamic and hydrofluoric acids and boron trifluoride complexes.  Emulsifying agents are preferably employed.  The reaction temperature may be from 20 DEG  to 150 DEG  C. The products are obtained in a high state of purity as fine spheroidal particles which generally become smaller as the ratio of water to phenol is increased up to about 9.  They may comprise isomeric forms of a compound, and when using two or more different phenolic compounds, the resulting mixture will contain proportions of compounds wherein two different phenolic radicals are attached to a single carbon atom.  The process may be batch, continuous or semi-continuous, employing one or more reactors provided with stirrers.  In the examples: bis-(3-tert.-butyl-5-methyl-2-hydroxyphenyl)-methane is prepared from tert.-butyl cresol and formaldehyde; bis-(4-hydroxyphenyl) methane from phenol and formaldehyde; bis-(3,4-dimethyl-2-hydroxy-phenyl) methane from 2,3-dimethyl-phenol and formaldehyde; 1,1-bis-(3-tert.-butyl-6-methyl-4-hydroxyphenyl) propane from 2-tert.-butyl-5-methyl-phenol and propionaldehyde; 1,1-bis-(3 - tert. - butyl - 5 - methyl - 4 - hydroxyphenyl) ethane from 2-methyl-6-tert.-butylphenol and acetaldehyde; bis-(3 - tert. - octyl - 6 - methyl-4 - hydroxyphenyl) methane from 2 - tert. - octyl - 5 - methylphenol and formaldehyde; bis - (3 - tert. - butyl - 6 - methyl - 4 - hydroxy-phenyl) benzylidene from 2 - tert. - butyl - 5 - methylphenol and benzaldehyde; and bis-(3-tert. - butyl - 5 - isopropyl - 2 - hydroxyphenyl) methane from 2-tert.-butyl-4-isopropylphenol and formaldehyde.

Title: Method for the control of the electric power supplied from an alternating-current main to a consumer and an apparatus for carrying out the method
IPC: H02M5/257
Filed: 1978-05-26
Abstract: In regulating power by phase control, the deviations of the load current from the sinusoidal variation should be small and occur at a high frequency so that they can be suppressed by simple filters. For this purpose, the on time is controlled with high keying frequency over each half wave of the alternating mains voltage, in such a manner that the mean value of the switched current tracks a sinusoidal wave. A nominal sinusoidal voltage is generated by means of a first circuit arrangement (R5, R6, P2, R7, G2). An actual voltage is derived from a load current by means of a second circuit arrangement (R1, G3). A comparison circuit (V2) outputs an output signal when the actual voltage is greater than the nominal voltage. A pulse oscillator (10) outputs high-frequency square wave pulses to the set input of a flip flop (FF), the reset input of which is connected to the output of the comparison circuit. The output signal of the flip flop (FF) controls a semiconductor switch (T1) which is connected to one arm of a rectifier bridge (G1), the other arm of which is located in the load circuit. An output signal of the flip flop (FF), generated in the set state of the flip flop (FF), keeps the semi-conductor switch (T1) in its conducting state. <IMAGE>
