Patent ES-368953-A1 (ES)
Title: Control systems including a safety circuit for direct current electric motors
IPC: H02P7/28
Filed: 1969-06-30
Abstract: A series motor 4 is supplied from battery 1 through thyristor 7 having a commutating arrangement comprising capacitor 22 coupled between rectifiers 7,21, which are triggered alternately, the charge on the capacitor being increased by the action of transformer 25. Triggering signals for the rectifiers 7, 21, are derived from an astable multivibrator, the passage of triggering pulses for the thyristor 7 being prevented when a reactor is saturated by coil 6 in series with the motor. The level of armature current to produce saturation is varied by adjusting the position of a permanent magnet. The trigger network for the rectifier 21 comprises a control transistor which is coupled to the trigger network for the rectifier 7. When the latter conducts, the control transistor also conducts, the next succeeding pulse to the thyristor 21 being prevented whereby the period of conduction of the thyristor 7 is maintained provided that the armature current remains below a predetermined level. Coils 13, 14, of reversing contactors 9, 10, are in parallel with the thyristor 7, so that, if the conduction period of the thyristor is prolonged, the current through the coils decays and the voltage across resistor 17 decreases. A signal is then developed to prevent the passage of triggering pulses to the thyristor 7.

Title: Indeneacetic acids
IPC: C07C315/04
Filed: 1977-01-25
Abstract: 5-Fluoro-2-methyl-1-(p-methylsulphinylbenzylidene)indenyl-3-acetic acid or its salts are prepared. The said acid is obtained by condensing 5-fluoro-2-methyl-1-R1-benzylindene, where R1 is p-methylthio or p-methylsulphinyl, with glyoxylic acid, its salt or ester to give the corresponding 5-fluoro-2-methyl-1-(p-methylthio- (or methylsulphinyl)benzyl)indenylidene-3-acetic acid, its salt or ester. If R1 is p-methylsulphinyl, the indenylidene compound is isomerised to indenyl-3-acetic acid. If R1 denotes methylthio, then the resulting indenylidene-3-acetic acid is isomerised to 5-fluoro-2-methyl-1-(p-methylthiobenzylidene)indenyl-3-acetic acid and the p-methylthio radical is then oxidised to the p-methylsulphinyl group. However, the oxidation can also be carried out first and the isomerisation subsequently. The said compounds can be used as active agents in anti-inflammatory medicaments.
