Patent DE-4022262-A1 (DE)
Inventor: PFLAUM ECKHARD DR ING
IPC: H01H33/59
Filed: 1990-07-12
Abstract: In order to make synchronous switching possible in the operation of a high-voltage power switch fitted with a hydraulic drive by means of a triggering control device (16), the available hydraulic pressure in the hydraulic drive system (2) is used as a correction factor to determine the triggering delay. The hydraulic pressure in the hydraulic system repeatedly falls within a pump cycle (12) to a minimum, to be brought up to the maximum again by pumping in hydraulic fluid from a tank (7). As the pressure drop occurs according to a certain time function, it is possible to calculate the hydraulic pressure from the time elapsed since the beginning of the cycle. This obviates the need for continuous measurement of the hydraulic pressure. The invention may be advantageously used in synchronous switches.

Title: 2-Equiv. coupler prodn. from 4-equiv. coupler - by introducing leaving gp. using selenium or tellurium cpd. for preliminary electrophilic reaction
Inventor: BERGTHALLER PETER DR
IPC: C07D401/04
Filed: 1990-12-18
Abstract: Prodn. of a 2-equiv. coupler Cp-Nu (I) involves reacting a 4-equiv. coupler Cp-H (II) or a corresp. coupler with a COOH, CHO or SO3H gp. in the coupling position with either (a) a cpd. (IV) contg. positive Se or Te and (the anion) of a cpd. Nu-H (III) or (b) a prim. prod. formed from (III) and (IV) and eliminating Se or Te or a Se or Te cpd. of low valency. Nu = the gp. of a cpd. (III) released during colour development, the H atom of (III) being attached to O or N. (I) is useful in colour photographic materials, e.g. negative and reversal film and colour paper. Introduction of Se or Te in the coupling position by electrophilic reaction makes it possible then to introduce O- or N-fugitive gps. by addn. of nucleophilic exchange. In an example, a soln. of 25 g. 1-trichlorophenyl-3-(2-chloro -5- tetradecanoylamino)-anilinopyrazol-5-one in 400 ml. i-PrOH was treated with 2.8 g. fine SeO2 powder and stirred 10 hrs. at room temp. 300 ml. toluene at 50 deg.C were added then the dark suspension was evapd. to dryness in vacuo. The residue was taken up in 100 ml. anhydrous dioxane and treated with 6 g. phenyl benzotriazole-5-carboylate and 4 g. tetramethylguanidine. The resultant blood-red soln. was heated 40 min. at up to 90 deg.C, then evapd. to dryness in vacuo. The residue was worked up and purified, giving an isomer mixt. of the 2-equiv. coupler. Crystallisation from acetonitrile gave 7.1 g. of the DIR coupler 1-trichlorophenyl-3-(2-chloro-5-tetradecanoylamino) -anilino-4- (phenoxycarbonyl-benzotriazol-1-yl)-pyrazol-5-one, m.pt. 148-152 deg.C.
